OData Control

Properties   Methods   Events   Config Settings   Errors  

The OData control implements the Open Data Protocol (OData). It can be used to query, parse, and update or modify data contained within an OData service.

Syntax

OData

Remarks

The OData Control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The OData component allows you to easily query OData services and create, update, and delete entries within a service. To query a service, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to query. Optionally you can set the Query*** properties to filter the results. QueryService can then be called to retrieve the results (which can be viewed via the Entry*** properties).

Example 1. Query a Service: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.QueryService()

To create a new entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the collection within the service that you wish to add the entry to. The Entry*** properties can be set to the values you wish to use to create the entry. CreateEntry can then be called to create the entry.

Example 2. Create a New Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products" OData1.EntryProperties OData1.CreateEntry()

If you wish to update an entry, you can set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to update. The Entry*** properties can be set to the values you wish to update. UpdateEntry can then be called to update the entry.

Example 3. Update an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" // Index 1 is the "Name" property. OData1.EntryProperties[1].Value = "MyNewName" OData1.UpdateEntry()

Deleting an entry requires that you first set the ServiceRootURI to the service's root URI and ResourcePath to the specific entry you wish to delete. DeleteEntry can then be called to delete the entry.

Example 4. Delete an Entry: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.ResourcePath = "Products(1)" OData1.DeleteEntry()

In addition to querying a service and manipulating its containing data, the OData component also allows you to retrieve the schema (metadata document) to determine the structure of a service. After setting ServiceRootURI to the root URI of the service, GetSchema can be called to retrieve the metadata document. The Schema*** properties will be populated upon successful retrieval of the metadata document allowing you to identify the structure of the service.

Example 5. Retrieve the Scheme: OData1.ServiceRootURI = "http://services.odata.org/OData/OData.svc" OData1.GetSchema()

Authorization Property (OData Control)

This property includes the Authorization string to be sent to the server.

Syntax

odatacontrol.Authorization[=string]

Default Value

""

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

Data Type

String

AuthScheme Property (OData Control)

This property specifies the authentication scheme to use when server authentication is required.

Syntax

odatacontrol.AuthScheme[=integer]

Possible Values

authBasic(0), 
authDigest(1), 
authProprietary(2), 
authNone(3), 
authNtlm(4), 
authNegotiate(5), 
authOAuth(6)

Default Value

0

Remarks

This property will tell the control which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the control will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the control.

For security, changing the value of this property will cause the control to clear the values of User, Password, and Authorization.

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

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.

Config Method (OData Control)

Sets or retrieves a configuration setting.

Syntax

odatacontrol.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.

CreateEntry Method (OData Control)

This method creates a new entry within the specified OData service resource.

Syntax

odatacontrol.CreateEntry 

Remarks

The component will use the items contained within EntryProperties to create a new entry within the feed service resource by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

Upon a successful creation, all previous entries contained by the component, before the CreateEntry call, will be cleared and replaced with the response entry data. EntryIndex will then be set to 0 (the first entry within the response), populating the EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, and EntryProperties properties. OtherHeaders will also be cleared and thus will need to be reset accordingly with each call made.

CustomRequest Method (OData Control)

This method sends a request to the specified URL using the HTTPMethod and PostData provided.

Syntax

odatacontrol.CustomRequest HTTPMethod, URL, PostData

Remarks

This method sends a custom request to the specified URL. The type of request sent is determined by HTTPMethod (e.g., POST) and the data sent are determined by PostData. If a custom request does not require data to be sent, simply set the PostData parameter to an empty string.

Note: All values specified are taken as entered.

OtherHeaders can be used to specify any additional headers you would like to be sent in the custom request.

The search results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the TransferredHeaders property as well as through the Header event.

The control will then attempt to parse the search results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex also will be set to 1, thus populating EntryProperties.

DeleteEntry Method (OData Control)

This method deletes an entry within an OData service resource.

Syntax

odatacontrol.DeleteEntry 

Remarks

The component will delete the entry, of an OData service resource, specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath).

An "If-Match" header will be sent in the delete request with the value contained within EntryETag.

Upon a successful entry deletion, all previous entries contained by the component, before the DeleteEntry call, will be cleared. OtherHeaders also will be cleared and thus will need to be reset accordingly with each call made.

GetEntryProperty Method (OData Control)

This method gets an OData entry property.

Syntax

odatacontrol.GetEntryProperty XPath

Remarks

This method is intended to extend the functionality of the OData control and will retrieve the value of the entry property specified by XPath. XPath is the XPath of the element or attribute according to the following convention: entry[x]/element@attribute. The @attribute part is optional. When EntryIndex is set to an index greater than or equal to zero, a relative path also can be used: property or property@attribute. When a relative path is specified, the value of the specified XPath will be returned for the entry identified by EntryIndex.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element, and attribute can be any attribute of that field. If an attribute is not supplied, the GetEntryProperty method will return the text portion of property.

Example 1. Attribute Not Supplied: ODataControl.GetEntryProperty("entry[5]/content/properties/ID") ODataControl.GetEntryProperty("entry[5]/content/properties/ID@type")

Example 2. Relative Path: In the following example, a relative path is used to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.GetEntryProperty("ID") ODataControl.GetEntryProperty("ID@type") ODataControl.GetEntryProperty("Address/State")

GetSchema Method (OData Control)

This method retrieves the schema for a service.

Syntax

odatacontrol.GetSchema 

Remarks

This method will retrieve the schema (metadata document) of the service specified by ServiceRootURI.

Upon successful retrieval of the schema, set SchemaEntityIndex to retrieve the names of the entities contained within the schema along with their keys, properties, and navigation properties.

Additional details about the schema can be retrieved via XPath.

HasXPath Method (OData Control)

This method determines whether a specific element exists in the document.

Syntax

odatacontrol.HasXPath XPath

Remarks

This method determines whether a particular XPath exists within the document. This may be used to check if a path exists before setting it through XPath.

This method returns True if the xpath exists, and False if not.

See XPath for details on the XPath syntax.

QueryService Method (OData Control)

This method queries an OData service using the specified parameters.

Syntax

odatacontrol.QueryService 

Remarks

This method queries an OData feed specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath) using the query options specified in the Query*** properties and OtherQueryOptions. To retrieve an OData feed, without performing any filtering, you can leave Query*** and OtherQueryOptions empty and call QueryService.

The query results are delivered in the TransferredData property, as well as through the Transfer event. The response headers can be retrieved through the ParsedHeaders property as well as through the Header event.

The control will attempt to parse the query results. Upon successfully parsing the response, Channel will be set with their associated feed element values and EntryCount will be populated with the total number of entries contained within the feed. EntryIndex will also be set to 1, thus populating EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, EntryProperties, and ResourcePath.

Reset Method (OData Control)

This method resets all of properties of the control.

Syntax

odatacontrol.Reset 

Remarks

The Reset method resets all properties to the control's default settings. This is an easy way to clear all of the property values before repopulating the OData feed.

SetEntryProperty Method (OData Control)

This method is used to set an OData entry property.

Syntax

odatacontrol.SetEntryProperty XPath, Value

Remarks

This method is intended to extend functionality of the OData control and will set the value of the entry property (specified by XPath) to the specified Value. Therefore, the value of the corresponding property will be updated within EntryProperties.

XPath is the XPath of the element or attribute according to the following convention: entry[x]/element. When EntryIndex is set to an index greater than or equal to zero, a relative path can also be used: property. When a relative path is specified, the control will use the specified EntryIndex along with the property specified to update the EntryProperty value.

entry[x] is the feed's xth entry (or any other root-level child), where the indexer x starts at 1.

property is any child of the property's element.

Example 1. Set Properties: ODataControl.SetEntryProperty("entry[5]/content/properties/Name", "MyNewName") Example 2. Retrieve Properties:

The following example uses a relative path to retrieve properties of the first feed entry: ODataControl.EntryIndex = 1 ODataControl.SetEntryProperty("Name", "MyNewName") ODataControl.SetEntryProperty("Address/State", "NC")

SetSchemaEntity Method (OData Control)

This method sets the schema entity.

Syntax

odatacontrol.SetSchemaEntity Name

Remarks

The control will set the schema entity to the Name specified. Once set, you can view the keys (via SchemaKeys), properties (via SchemaProperty), and navigation properties (via SchemaAssociation) contained within the specified entity.

SetSchemaProperty Method (OData Control)

This method sets the schema property.

Syntax

odatacontrol.SetSchemaProperty Name

Remarks

The control will set the schema property to the Name specified. Once set, you can view the details of the property (via SchemaProperty) along with the complex type details (via SchemaTypeField); provided that the property is derived from the complex type.

SetSchemaType Method (OData Control)

This method sets the schema type.

Syntax

odatacontrol.SetSchemaType Name

Remarks

The control will set the schema type to the Name specified. Once set, you can view the details of the complex type (via SchemaTypeField).

UpdateEntry Method (OData Control)

This method updates an OData entry.

Syntax

odatacontrol.UpdateEntry 

Remarks

The control will update the OData entry specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath). It also will update the OData entry with the elements specified by EntryProperties.

Upon a successful update, all previous entries contained by the component, before the UpdateEntry call, will be cleared and replaced with the response entry data. EntryIndex will then be set to zero (the first entry within the response), populating the EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, EntryProperties, and ResourcePath properties. OtherHeaders will also be cleared and thus will need to be reset accordingly with each call made.

UpdateProperty Method (OData Control)

This method updates an OData entry property.

Syntax

odatacontrol.UpdateProperty XPath, Value

Remarks

The control will update the OData entry specified by ServiceRootURI and ResourcePath (ServiceRootURI/ResourcePath). It will update only the single entry property specified by XPath with the specified Value.

Upon a successful update, all previous entries contained by the component, before the UpdateProperty call, will be cleared and replaced with the response entry data. EntryIndex will then be set to zero (the first entry within the response), populating the EntryAuthor, EntryETag, EntryTitle, EntrySummary, EntryUpdated, EntryLinks, EntryProperties, and ResourcePath. OtherHeaders will also be cleared and thus will need to be reset accordingly with each call made.

Connected Event (OData Control)

Fired immediately after a connection completes (or fails).

Syntax

Sub odatacontrol_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.

Fired when a connection is closed.

Syntax

Sub odatacontrol_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 (OData Control)

This event fires when a document finishes transferring.

Syntax

Sub odatacontrol_EndTransfer(Direction As Integer)

The entry links are provided through EntryLinks.

Error Event (OData Control)

Fired when information is available about errors during data delivery.

Syntax

Sub odatacontrol_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 (OData Control)

Fired every time a header line comes in.

Syntax

Sub odatacontrol_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 (OData Control)

Fired once for each log message.

Syntax

Sub odatacontrol_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"

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.

Sub odatacontrol_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 (OData Control)

Fired when secure connection progress messages are available.
