CardDAV Control

Properties   Methods   Events   Config Settings   Errors  

The CardDAV control makes it easy to access, share, manage, upload, and download contact data based on the vCard format within a CardDAV server.

Syntax

CardDAV

Remarks

The CardDAV control allows management of address books and their contacts. Capabilities include creation, deletion, updating, listing, copying, and moving of contacts and address books. The following sections provide additional details about common operations.

Authentication

This control may require authentication via OAuth 2.0 depending on the provider. For example Google requires OAuth 2.0. Perform OAuth authentication using the OAuth control or a separate process. Once complete, you should have an authorization string which looks like:

Bearer ACCESS_TOKEN_VALUE

Addressing Resources

The CardDAV control allows resources to be addressed using a resource URI. There is no standard format for a resource URI, though in most cases the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name".

Google uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" to access the default address book. Below is an example of using the GetAddressbookReport method, which makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

To add, delete, update, copy or move a contact from an address book, add its file name at the end of the address book URI, which typically has a vcf extension. Usually the filename of a contact is the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources.

Listing Address Books

ListAddressbooks lists all address books that the current user can access. When this method is called the control will automatically perform a series of requests to obtain the calendar list. First, the control will send a PROPFIND request to the specified base URL to obtain the current-user-principle. Once the current user has been found, the control will then use that information to send a second PROPFIND request to get addressbook-home-set for the user. The addressbook-home-set is then used by the control to make a final PROPFIND request to get the list of address books for the user.

Once this method returns, the control will populate the Addressbook* properties. For example:

cardDAV.ListAddressbooks("https://mydavserver/.well-known/carddav/Address_Book_Name"); for (int i = 0; i < cardDAV.Addressbooks.Count; i++) { string url = cardDAV.Addressbooks[i].URL; string displayName = cardDAV.Addressbooks[i].DisplayName; }

Managing Address Books

To create an address book use the CreateAddressbook method. The resource URI would be similar to "https://mydavserver/.well-known/carddav/New_Address_Book" and it should be unique. The last part of the URI is not the display name of the address book, but is needed to retrieve/update/delete the addressbook. Specify the display name and the description as arguments when calling CreateAddressbook.

To update an address book iterate through Addressbooks to find the index of the address book to be updated. Set the properties of the address book to the desired values and then make a call to UpdateAddressbook.

To delete an address book use the DeleteAddressbook method and provide the URI of the address book. The following example shows how to create, update and delete an address book: //create an address book cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/New_Address_Book", "display_name", "description"); //update the address book cardDAV.Addressbooks[0].DisplayName = "display_name_updated"; cardDAV.Addressbooks[0].Description = "description_updated"; cardDAV.UpdateAddressbook("https://mydavserver/.well-known/carddav/New_Address_Book", 0); //delete the address book cardDAV.DeleteAddressbook("https://mydavserver/.well-known/carddav/New_Address_Book");

Listing Contacts

To retrieve the contacts of an address book, invoke the GetAddressbookReport method, which sends an addressbook-query request to the address book located at the specified ResourceURI. The response to an addressbook-query report will be parsed by the control, and information about the individual contacts will be provided in the ContactDetails event.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

• AddressLabels
• Addresses
• Agent
• Anniversary
• BirthDay
• Categories
• Classification
• ContactURL
• CustomProperties
• Depth
• EMails
• FormattedName

For example: cardDAV.User = "myusername"; cardDAV.Password = "mypassword"; cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/user@gmail.com/lists/default"); The following code inside the ContactDetails event will print the formatted name, phone number and email for each contact: Private Sub CardDAV_ContactDetails(ResourceURI As String, ResponseStatus As String, ETag As String, ContactData As String) Debug.Print cardDAV.FormattedName + " " + cardDAV.PhoneNumbers[0].Value + " " + cardDAV.EMails[0].Value End Sub The output from the above code will look like this:

John Smith  123-456-7890  john@example.com
Jane Doe  555-555-5555  jane@example.com
Alice Johnson 987-654-3210  alice@example.com 

Managing Contacts

The CreateContact, UpdateContact, DeleteContact, CopyContact, and MoveContact methods provide a way to manage individual contacts within an address book.

When calling CreateContact it is necessary to specify at least the formatted name of the object the contact represents. Additional information can be added to the contact by setting additional properties. Please refer to the CreateContact documentation for a complete list of applicable properties.

When calling UpdateContact set the properties to change for the contact and then make a call to UpdateContact.

When calling MoveContact or CopyContact specify the URI of the contact to be copied or moved, and the destination URI. When calling DeleteContact specify the URI of the contact to delete.

The example below shows a few possible operations: cardDAV.User = "username"; cardDAV.Password = "password"; //create a contact cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.EMails.Add(new CardCustomProp("email", "john@gmail.com")); CardCustomProp address1 = new CardCustomProp("address", ";;123 Main Street;Any Town;State;1234;Country Name"); address1.Attribute = "TYPE=home"; //optional cardDAV.Addresses.Add(address1); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); //update the contact cardDAV.NickName = "Johny"; cardDAV.PhoneNumbers[0] = new CardCustomProp("tel", "0123456789"); cardDAV.UpdateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); //move the contact cardDAV.MoveContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf", "https://mydavserver/.well-known/carddav/Another_Address_book/123456789.vcf"); //delete the contact cardDAV.DeleteContact("https://mydavserver/.well-known/carddav/Another_Address_book/123456789.vcf");

Creating and Retrieving Contacts using vCards

Another way to create a contact is by using ImportVCF to import all the data from a vCard object. For example: String vCard = File.ReadAllText("path/to/vcf/file"); cardDAV.ImportVCF(vCard); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); Retrieve a contact by using GetContact, then make a call to ExportVCF, which will convert the retrieved data to a vCard object. This can later be written to a standard VCF file. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); File.WriteAllText("path/to/vcf/file", cardDAV.ExportVCF());

Data Type

String

FollowRedirects Property (CardDAV Control)

Determines what happens when the server issues a redirect.

Syntax

carddavcontrol.FollowRedirects[=integer]

Possible Values

frNever(0), 
frAlways(1), 
frSameScheme(2)

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the control returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same; otherwise, the control fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the control fails with an error instead.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

The headers must follow the format Header: Value as described in the HTTP specifications. Header lines should be separated by CRLF (Chr$(13) & Chr$(10)) .

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for extending the functionality of the control beyond what is provided.

For CardDAV, the "If-Match" header is extremely useful. After adding a contact with CreateContact or retrieving a contact with GetContact, the ETag property will contain a value indicating the current state of the contact. If you wish to update the contact, you may pass this returned ETag in an "If-Match" header. If the contact on the server has been modified since you retrieved it (and the ETag on the server has changed), then the CreateContact will fail with an HTTP Protocol Error: "409 Conflict", which indicates there is a conflict between the version you're trying to update and the current version on the sever. For instance: cardDAV.OtherHeaders = "If-Match: 1900-1900\r\ n";

The SSLServerCertStoreType property denotes the type of the certificate store specified by SSLServerCertStore. If the store is password-protected, specify the password in SSLServerCertStorePassword.

SSLServerCertStore is used in conjunction with the SSLServerCertSubject property to specify client certificates. If SSLServerCertStore has a value, and SSLServerCertSubject or SSLServerCertEncoded is set, a search for a certificate is initiated. Please see the SSLServerCertSubject property for details.

Designations of certificate stores are platform dependent.

The following designations are the most common User and Machine certificate stores in Windows:

When the certificate store type is cstPFXFile, this property must be set to the name of the file. When the type is cstPFXBlob, the property must be set to the binary contents of a PFX file (i.e., PKCS#12 certificate store).

To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertStoreB.

This property is read-only.

CardDAV.Reset() CardDAV.AddCustomProperty("propname1", "propvalue1") CardDAV.AddCustomProperty("propname2", "propvalue2") Example using Custom Property arrays: CardDAV.Reset() CardDAV.CustomPropertyCount = 2 CardDAV.CustomPropertyName (0) = "propname1" CardDAV.CustomPropertyValue(0) = "propvalue1" CardDAV.CustomPropertyName (1) = "propname2" CardDAV.CustomPropertyValue(1) = "propvalue2"

Config Method (CardDAV Control)

Sets or retrieves a configuration setting.

Syntax

carddavcontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CopyContact Method (CardDAV Control)

Copy contact to a new location.

Syntax

carddavcontrol.CopyContact SourceResourceURI, DestinationResourceURI

Remarks

The CopyContact method will copy the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.

Note that neither Yahoo nor Google CardDAV servers support copying, or moving address book resources.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

CreateAddressbook Method (CardDAV Control)

Creates a new address book collection resource.

Syntax

carddavcontrol.CreateAddressbook ResourceURI, DisplayName, Description

Remarks

The CreateAddressbook method creates a new address book collection resource. A server MAY restrict address book collection creation to particular collections.

Creating address book collections is not supported by all CardDAV servers. Some address book stores only support one address book per user (or principal), and those are typically pre-created for each account.

The DisplayName and Description parameters should be set to a human readable display name and description of the address book.

To successfully create an address book, the ResourceURI cannot already exist, and must point to a valid location where a new address book can be created. The DAV:bind privilege MUST be granted to the current user on the parent collection of the specified ResourceURI.

The following example shows how to create a simple new address book collection resource. cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/TestAddressbook1", "My Display Name", "My Addressbook Description");

Note that Google does not support creating a new address book through CardDAV.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

CreateContact Method (CardDAV Control)

Adds a contact resource at the specified ResourceURI using the CardDAV PUT method.

Syntax

carddavcontrol.CreateContact ResourceURI

Remarks

This method adds a new contact to the address book collection at the specified ResourceURI. The ResourceURI must be a fully qualified URL to the location on the CardDAV server to which this contact will be saved. If the ResourceURI already exists, the contact at that URI will be overwritten.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

DeleteAddressbook Method (CardDAV Control)

Deletes an address book collection resource.

Syntax

carddavcontrol.DeleteAddressbook ResourceURI

Remarks

This method deletes an address book collection resource specified by ResourceURI. To successfully delete an address book, the ResourceURI should already exist, and must point to a valid location where an address book can be deleted. The DAV:bind privilege MUST be granted to the current user on the parent collection of the specified ResourceURI.

The following example shows how to delete an address book collection resource: cardDAV.DeleteAddressbook("https://mydavserver/.well-known/carddav/TestAddressbook1"); In a NextCloud server, if all address books are deleted, a new address book "Contacts" is automatically created.

Note that Google does not support deleting an address book through CardDAV.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

DeleteContact Method (CardDAV Control)

Deletes a resource.

Syntax

carddavcontrol.DeleteContact ResourceURI

Remarks

This method is used to delete the resource specified by ResourceURI. ResourceURI is first removed from any collection in which it is contained, it is then removed from the server.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name".

Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

DoEvents Method (CardDAV Control)

This method processes events from the internal message queue.

Syntax

carddavcontrol.DoEvents 

Remarks

When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.

ExportVCF Method (CardDAV Control)

Generates a contact from the properties in the vCard format.

Syntax

carddavcontrol.ExportVCF 

Remarks

The ExportVCF method is used to create a contact and export it in the vCard/VCF format, which can then be saved to disk and imported using any other software, even those that do not support CardDAV. The ExportVCF method will create the exact same data as the CreateContact method sends when adding or updating a contact to an address book.

Note that if ExportVCF is called immediately after a successful GetContact, the unmodified data returned from the CardDAV server will be returned. However if any properties are changed between the GetContact and ExportVCF calls, the control will generate and return a brand new contact.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

GetAddressbookOptions Method (CardDAV Control)

Retrieves options for the ResourceURI to determine whether it supports address book access.

Syntax

carddavcontrol.GetAddressbookOptions ResourceURI

Remarks

This method sends a request to the indicated ResourceURI. The server's response is available in the Header event. If a server supports CardDAV address book access, the "DAV" header will contain the string "address book". The allowable CardDAV and WebDAV methods may also be returned in the "Allow" header.

For instance, the following headers may be returned from a call to the GetAddressbookOptions method:

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book.

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

GetAddressbookReport Method (CardDAV Control)

Generates a report on the indicated address book.

Syntax

carddavcontrol.GetAddressbookReport ResourceURI

Remarks

This method is used to send a request to the address book located at the specified ResourceURI. The ReportFilter can be used to filter out and return only the contacts you wish to receive. The response to an addressbook-query report will be parsed by the control, and information about the individual contacts will be provided in the ContactDetails event.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

For example: cardDAV.User = "myusername"; cardDAV.Password = "mypassword"; cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/user@gmail.com/lists/default"); The following code inside the ContactDetails event will print the formatted name, phone number and email for each contact: Private Sub CardDAV_ContactDetails(ResourceURI As String, ResponseStatus As String, ETag As String, ContactData As String) Debug.Print cardDAV.FormattedName + " " + cardDAV.PhoneNumbers[0].Value + " " + cardDAV.EMails[0].Value End Sub The output from the above code will look like this:

John Smith  123-456-7890  john@example.com
Jane Doe  555-555-5555  jane@example.com

Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

GetContact Method (CardDAV Control)

Retrieves a single contact from the CardDAV server.

Syntax

carddavcontrol.GetContact ResourceURI

Remarks

This method retrieves a single contact from a server. The ResourceURI points to the exact location of the vCard (*.vcf) file you wish to retrieve. (If you do not know the URL of the contact you need, you can use GetAddressbookReport along with the ReportFilter property to find it.)

The contact will be retrieved using the WebDAV GET method. The full response is delivered through the Transfer event and the HTTP response headers through the Header event. After a contact is retrieved with this method, the control parses the contact data into properties. You may then edit these properties and use UpdateContact to update the contact resource.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

ImportVCF Method (CardDAV Control)

Imports contact data (contained in a VCF file) into the control's property list.

Syntax

carddavcontrol.ImportVCF ContactData

Remarks

This method is used to load contact data from an external source into the control. You may then submit this data with a call to UpdateContact or CreateContact. If you edit any of the control properties between importing and calling UpdateContact or CreateContact, the control will re-generate the request itself. If no properties are changed, the imported data will be submitted unaltered when calling UpdateContact or CreateContact.

As the contact data is imported, the control will scan ContactData for any contacts. Each time a contact is discovered, the ContactDetails event will fire, and the contact properties will be updated.

After ImportVCF completes, the contact properties will be set to the most recent contact found in ContactData.

Interrupt Method (CardDAV Control)

This method interrupts the current method.

Syntax

carddavcontrol.Interrupt 

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListAddressbooks Method (CardDAV Control)

Lists all address books that the current user can access.

Syntax

carddavcontrol.ListAddressbooks baseURL

Remarks

This method lists all address books the user can access.

The BaseURL parameter must be set to the base CardDAV URL for the server. For instance in the case of Google this is https://www.googleapis.com/carddav/v1/principals/. Other servers may use a format like https://mydavserver/.well-known/carddav/.

When this method is called the control will automatically perform a series of requests to obtain the calendar list. First, the control will send a PROPFIND request to the specified base URL to obtain the current-user-principle. Once the current user has been found, the control will then use that information to send a second PROPFIND request to get addressbook-home-set for the user. The addressbook-home-set is then used by the control to make a final PROPFIND request to get the list of address books for the user.

Once this method returns, the control will populate the Addressbook* properties. For example:

cardDAV.ListAddressbooks("https://mydavserver/.well-known/carddav/Address_Book_Name"); for (int i = 0; i < cardDAV.Addressbooks.Count; i++) { string url = cardDAV.Addressbooks[i].URL; string displayName = cardDAV.Addressbooks[i].DisplayName; }

MoveContact Method (CardDAV Control)

Moves one contact resource to a new location.

Syntax

carddavcontrol.MoveContact SourceResourceURI, DestinationResourceURI

Remarks

This method will move the resource indicated by SourceResourceURI to a new location under the resource indicated by DestinationResourceURI.

Note that Google CardDAV servers do not support copying, or moving contacts.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

Reset Method (CardDAV Control)

Reset the control.

Syntax

carddavcontrol.Reset 

Remarks

This method will reset the control's properties to their default values.

SendCustomRequest Method (CardDAV Control)

Sends a custom request to the server.

Syntax

carddavcontrol.SendCustomRequest HttpMethod, Url, RequestBody

Remarks

Allows users to send personalized HTTP commands to a CardDAV server.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• PATCH
• PROPFIND
• PROPPATCH
• MKCOL
• COPY
• MOVE

The value passed for URL is used as the location the request is made to. The RequestBody parameter is used to provide the component with the request body for the request. If no request body is needed for the request, the RequestBody parameter should also then be set to an empty string. Here is an example of how to create a contact: string contactData = @"BEGIN:VCARD PRODID:/n software IPWorks CardDAV Component - www.nsoftware.com UID:20240307T160700Z ANNIVERSARY:19961212 FN:John NICKNAME:John PHOTO:TestURI EMAIL:test@test.com TEL:123456789 END:VCARD"; cardDAV.SendCustomRequest("PUT", "https://mydavserver/.well-known/carddav/AddressbookName/contact.ics", contactData);

UpdateAddressbook Method (CardDAV Control)

Updates an address book collection resource.

Syntax

carddavcontrol.UpdateAddressbook ResourceURI, ABIndex

Remarks

This method updates an existing address book collection at the specified ResourceURI. To successfully update an address book, the ResourceURI should already exist, and must point to a valid location where an address book is saved. First iterate through Addressbooks to find the index of the address book to be updated. Set the properties of the address book to the desired values and then make a call to UpdateAddressbook.

The following example shows how to update an address book collection resource: cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/TestAddressbook1", "display_name", "description"); cardDAV.Addressbooks[0].DisplayName = "display_name_updated"; cardDAV.Addressbooks[0].Description = "description_updated"; cardDAV.UpdateAddressbook("https://mydavserver/.well-known/carddav/TestAddressbook1", 0);

Note that Google does not support updating an address book through CardDAV.

There is no standard format for a resource URI. Google for instance, uses "https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default" address to access the default address book. Here is an example of using the GetAddressbookReport, that makes a REPORT request to the given URI in the CardDAV server. cardDAV.GetAddressbookReport("https://www.googleapis.com/carddav/v1/principals/username@gmail.com/lists/default");

Generally, the URI format would be something like "https://mydavserver/.well-known/carddav/Address_Book_Name". To add, delete, update, copy or move a contact from an address book, you can add its file name at the end of the address book URI, which typically has a vcf extension (not always). Usually the filename of a contact would be the same as the UID of the contact plus the vcf extension, but this depends on the way the CardDAV server manages resources. This is the resource URI you must use to retrieve the contact with GetContact. For example: cardDAV.GetContact("https://mydavserver/.well-known/carddav/Address_Book_Name/1234567890.vcf");

The examples below show a few possible transactions: cardDAV.User = "username"; cardDAV.Password = "password"; cardDAV.CreateAddressbook("https://mydavserver/.well-known/carddav/Address_Book_Name/", "My Address book", "My Address books"); cardDAV.FormattedName = "Mr. John Q. Public\, Esq."; cardDAV.PhoneNumbers.Add(new CardCustomProp("tel", "123456790")); cardDAV.CreateContact("https://mydavserver/.well-known/carddav/Address_Book_Name/123456789.vcf"); cardDAV.GetAddressbookReport("https://mydavserver/.well-known/carddav/Address_Book_Name/"); NextCloud's ResourceURIs always start with "http://www.nextcloud.com/remote.php/dav/addressbooks/users/" plus your user name, plus the name of your address book. For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

UpdateContact Method (CardDAV Control)

Updates a contact at the specified ResourceURI.

Syntax

carddavcontrol.UpdateContact ResourceURI

Remarks

This method updates an existing contact to the address book collection at the specified ResourceURI. The ResourceURI must be a fully qualified URL to the location on the CardDAV server to which this contact is saved.

The following properties are used when calling CreateContact, UpdateContact or ExportVCF, and will be filled after calling GetContact or ImportVCF. These will also be available from inside the ContactDetails event, which is fired for each contact received from the CardDAV server in response when calling GetAddressbookReport.

For instance: "http://www.nextcloud.com/remote.php/dav/addressbooks/users/username/Contacts" for the default address book. Contact resources are located directly under the "username/Contacts" or "username/My_Addressbook" path. Here the filename doesn't have to be identical to the UID.

Connected Event (CardDAV Control)

Fired immediately after a connection completes (or fails).

Syntax

Sub carddavcontrol_Connected(StatusCode As Integer, Description As String)

Remarks

If the connection is made normally, StatusCode is 0 and Description is "OK".

If the connection fails, StatusCode has the error code returned by the Transmission Control Protocol (TCP)/IP stack. Description contains a description of this code. The value of StatusCode is equal to the value of the error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

ConnectionStatus Event (CardDAV Control)

Fired to indicate changes in the connection state.

Syntax

Sub carddavcontrol_ConnectionStatus(ConnectionEvent As String, StatusCode As Integer, Description As String)

Remarks

This event is fired when the connection state changes: for example, completion of a firewall or proxy connection or completion of a security handshake.

The ConnectionEvent parameter indicates the type of connection event. Values may include the following:

ContactDetails Event (CardDAV Control)

Fires for each contact received.

Syntax

Sub carddavcontrol_ContactDetails(ResourceURI As String, ResponseStatus As String, ETag As String, ContactData As String)

Remarks

This event fires for each VCARD contact received in response to a GetAddressbookReport request. The ResourceURI parameter indicates the location of this particular contact on the CardDAV server, and the ETag parameter is used to indicate the current state of the contact. If the ETag is different from the value you have cached for the current ResourceURI, it means the contact has changed on the server since the last time you updated your cache. ResponseStatus indicates the HTTP status of CardDAV server received when attempting to retrieve this particular ResourceURI when it was building the report. The ContactData parameter contains the raw contact entry as returned by the CardDAV server. This data is also parsed into the following properties, and are valid for the current ResourceURI only inside this event.

Note that for a large address book you may not wish to return the full contents of each contact, as this could be a substantially large amount of data. In this case, set the ReportFilterReturnContactData property to false, and only the ResourceURI, ResponseStatus, and ETag parameters will be returned by the CardDAV server for each contact. The contents of the contact will not be returned, and the ContactData parameter will be empty.

Disconnected Event (CardDAV Control)

Fired when a connection is closed.

Syntax

Sub carddavcontrol_Disconnected(StatusCode As Integer, Description As String)

Remarks

If the connection is broken normally, StatusCode is 0 and Description is "OK".

If the connection is broken for any other reason, StatusCode has the error code returned by the Transmission Control Protocol (TCP/IP) subsystem. Description contains a description of this code. The value of StatusCode is equal to the value of the TCP/IP error. The corresponding Visual Basic error code can be obtained by adding 15001 to this value.

Please refer to the Error Codes section for more information.

EndTransfer Event (CardDAV Control)

This event is fired when a document finishes transferring.

Syntax

Sub carddavcontrol_EndTransfer(Direction As Integer)

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (CardDAV Control)

Fired when information is available about errors during data delivery.

Syntax

Sub carddavcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Header Event (CardDAV Control)

Fired every time a header line comes in.

Syntax

Sub carddavcontrol_Header(Field As String, Value As String)

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (CardDAV Control)

Fired once for each log message.

Syntax

Sub carddavcontrol_Log(LogLevel As Integer, Message As String, LogType As String)

Remarks

This event is fired once for each log message generated by the control. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

Redirect Event (CardDAV Control)

Fired when a redirection is received from the server.

Syntax

Sub carddavcontrol_Redirect(Location As String, Accept As Boolean)

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the control fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.

SetCookie Event (CardDAV Control)

Fired for every cookie set by the server.

Syntax

Sub carddavcontrol_SetCookie(Name As String, Value As String, Expires As String, Domain As String, Path As String, Secure As Boolean)

Remarks

This event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SSLServerAuthentication Event (CardDAV Control)

Fired after the server presents its certificate to the client.

Syntax

Sub carddavcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (CardDAV Control)

Fired when secure connection progress messages are available.

Syntax
