SharePoint Configuration
The control accepts one or more of the following configuration settings. Configuration 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.SPDocuments Configuration Settings
CheckInType: The type of check-in performed.This configuration option allows the check-in type to be specified when CheckIn is called. The valid arguments are:
The UseSOAP configuration option must be "true" for this option's use. | |||||||
CheckOutToLocal: Whether the file is to be checked out for offline editting.When this configuration option is set to True, the file checked out by CheckOut will be marked as
checked out for offline editting. This option defaults to False.
The UseSOAP configuration option must be "true" for this configuration option's use. | |||||||
DocComment: Used to set the first comment when adding a document.If the library to which the document is being added supports versioning, the comment associated with the initial addition may be set by specifying a value for this setting. | |||||||
DocMetaInfo: Specifies the metadata to be associated with a document when it is added.This may be set before calling Add to associate metadata with a document.
The format expected is "name1;value1;name2;value2" and so on.
For example, to specify the title and a custom column value you could do:
SPDocuments1.Config("DocMetaInfo=vti_title;SW|My New Title;MyColumn;New Value"); If you wish to set metadata on an existing document the UpdateItems method of the SPList control may be used. | |||||||
DocumentAuthor[i]: The author of the document indicated by index i.When StoreDocumentList is True, this setting returns the author of the document indicated by the index i returned by a
call to the List method.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentCheckedOutBy[i]: The user who has checked out the document indicated by index i.When StoreDocumentList is True, this setting returns the user who has checked out the document indicated by the index i
returned by a call to the List method. If the document is not checked out, this setting will be an empty string.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentCount: The number of documents returned by a call to List.When StoreDocumentList is True, this setting returns the number of documents returned by a call to the List method. | |||||||
DocumentCreated[i]: The date and time the document indicated by index i was created.When StoreDocumentList is True, this setting returns the date and time the document indicated by the index i
was created. The date/time will be formatted as "YYYY-MM-DD hh:mm:ss:".
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentFileName[i]: The filename of the document indicated by index i.When StoreDocumentList is True, this setting returns the filename of the document indicated by the index i.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentFileReference[i]: The file reference of the document indicated by index i.When StoreDocumentList is True, this setting returns the file reference (the path and filename) of the document indicated by the index i.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentIsFolder[i]: Whether the document indicated by index i is a folder.When StoreDocumentList is True, this setting returns whether the document indicated by the index i is a folder or not.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentModified[i]: The date and time the document indicated by index i was last modified.When StoreDocumentList is True, this setting specifies the date and time the document indicated by the index i
was last modified. The date/time will be formatted as "YYYY-MM-DD hh:mm:ss:".
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentSourceControlVersion[i]: The source control version of the document indicated by index i.When StoreDocumentList is True, this setting returns source control version of the document indicated by the index i.
Valid index values are from 0 to DocumentCount - 1. | |||||||
DocumentIndex: Selects a document.When StoreDocumentList is True, this configuration setting may be set to a value between 0 and DocumentCount - 1 in order to select a document. Once set, the following configuration settings will be populated: | |||||||
DocumentFieldCount: The number of fields for the current document.This configuration reflects the number of fields in the current document. This is relevant when setting DocumentFieldName and DocumentFieldValue configuration settings. | |||||||
DocumentFieldName[i]: The name of the field at the specified index.When queried outside of the Document Event, and StoreDocumentList is True, this setting returns the name of the field at index i for the document specified by DocumentIndex. Within the Document Event, setting the StoreDocumentList configuration is not necessary and this setting will return the value of the field at index i for the current document.
Valid index values are from 0 to DocumentFieldCount - 1. | |||||||
DocumentFieldValue[i]: The value of the field at the specified index.When queried outside of the Document Event, and StoreDocumentList is True, this setting returns the value of the field at index i for the document specified by DocumentIndex. Within the Document Event, setting the StoreDocumentList configuration is not necessary and this setting will return the value of the field at index i for the current document.
Valid index values are from 0 to DocumentFieldCount - 1. | |||||||
IncludedFields: The fields to request when calling List.This configuration setting accepts a comma separated list of field names that will be requested when calling List. The default value
is "LinkFilename,Created Date,Last Modified,Editor,CheckoutUser,owshiddenversion,FSObjType", and the control uses these values to
populate the Document Event parameters, as well as their corresponding configuration settings when StoreDocumentList is True. If the default fields are not requested, these values may be empty.
To obtain the values of the requested fields outside of the Document Event, StoreDocumentList must be set to True before calling List.
Then, set DocumentIndex, and use the DocumentFieldName and DocumentFieldValue configuration settings to obtain the name value pairs, like so:
int count = Int32.Parse(docs.Config("DocumentCount")); for (int i = 0; i < count; i++) { docs.Config("DocumentIndex=" + i); int fieldCount = Int32.Parse(docs.Config("DocumentFieldCount")); for (int j = 0; j < fieldCount; j++) { Console.WriteLine(docs.Config("DocumentFieldName[" + j + "]")); Console.WriteLine(docs.Config("DocumentFieldValue[" + j + "]")); } }Within the Document Event, setting the StoreDocumentList and DocumentIndex configuration settings is not necessary, and the DocumentFieldName and DocumentFieldValue configuration settings may be queried to obtain the values of the requested fields for the current document. | |||||||
IncludeFieldsWithViewId: Indicates whether to use the IncludedFields setting when using the ViewId setting.This configuration setting indicates whether to use IncludedFields when ViewId is set. By default, this setting is false. | |||||||
IncludeOrderById: Whether to request that results are ordered by Id when listing documents.When calling List this setting controls whether the results are ordered by Id. If ViewId is set to a view that does not include Id as a column this should be set to False so that the view results are returned correctly. The default value is True. | |||||||
LastModified: A date in RFC 1123 date format representing the date and time of the last modification to the file.If this configuration option is set, the server will compare the submitted lastModified value with the stored lastModified value during CheckOut.
If the values do not match, the CheckOut fails and an error is returned.
The UseSOAP configuration option must be "true" for this option's use. | |||||||
PagingId: Used to check for paged results from SharePoint.This configuration setting can be queried to see if more pages of results are available from SharePoint. If this setting returns a non-empty string, the List* method can be called again to fetch the next page of results. The RowLimit setting should be used to set the page size for paged results. | |||||||
Query: The query to be used while listing documents.This configuration setting is used by the List method.
Detailed information about the CAML Query Schema can be found at this URL: http://msdn.microsoft.com/en-us/library/ms467521.aspx | |||||||
RawEntry: Returns the raw entry for the listing inside.While in the Document event, this setting will provide the full XML entry for the current document. | |||||||
ResolveLibraryNames: Controls whether or not library names will automatically be resolved.Some Document Library names (such as those containing non-ASCII characters) will have an internal name different than their Display Name, and some operations on the Document Library require that the internal name is used rather than the Display Name. When this configuration option is set to "true" the control will automatically attempt to resolve the Display Name to the internal name when needed. The default is false. | |||||||
RowLimit: Limits the rows returned by ListItems.This configuration will limit the number of rows returned by a call to ListItems. If this is not specified, the default value is set by SharePoint. | |||||||
SiteURL: The complete URL for a service.The control will normally use the URL property to construct the URL for a specific service. This setting overrides the value of this URL. | |||||||
Scope: Sets the scope for the View used by the List method.This configuration can be used to set the Scope of the View that the List method uses to retrieve items from the list.
Valid input options are:
| |||||||
SOAPResponse: The response from the last request.This configuration setting will contain the entire SOAPResponse, or other HTTP response, that is received from the SharePoint Server. | |||||||
SOAPRequest: The contents of the request sent to the server.This setting will provides the full contents of the SOAP packet or other data sent to the server during a transaction. | |||||||
StoreDocumentList: Whether or not to store the Documents returned by the List method.When this setting is true the control will store the document details returned by List in memory. When false (default), the document details will only be accessible in the Document event. | |||||||
Subfolder: The subfolder of the specified document library.This configuration is used by the control when List is called to limit the file listing to
files in the specified Subfolder. When not set, all files in the document library will be
listed.
Note: This must contain the path to the folder which will include the document library name. | |||||||
FormBasedCookies: Holds the security cookies for Form-Based Authentication.This setting is automatically populated when AuthScheme is set to form based
and a method is called. If this setting is populated before calling a method, the control
will use the specified cookies.
If the cookies specified in this setting become invalid, set this to an empty string to clear the cookies before re-attempting authentication. | |||||||
SPOnlineSecurityCookies: Holds the security cookies for SharePoint Online.This setting is automatically populated when AuthScheme is set to SPOnline
and a method is called. If this setting is populated before calling a method the control
will use the specified cookies.
If the cookies specified in this setting become invalid, set this to empty string to clear the cookies before re-attempting authentication. | |||||||
SPOnlineSSO: Whether to use Single Sign On (SSO) with Active Directory Federation Services (ADFS).This setting may be set to True to use Single Sign On with Active Directory Federation Services (ADFS) to authenticate to SharePoint Online.
This is only applicable when AuthScheme is set to SPOnline. URL should be set to the SharePoint Online site URL.
For instance:
list.URL = "https://mycrm.sharepoint.com"; list.User = "test@test.com"; list.AuthScheme = SplistAuthSchemes.authSPOnline; list.Config("SPOnlineSSO=true"); list.Config("FollowRedirects=1"); list.List = "MyCustomList"; list.ListItems();You may also generate and use SPOnlineSecurityCookies. For instance: list.URL = "https://mycrm.sharepoint.com"; list.User = "test@test.com"; list.AuthScheme = SplistAuthSchemes.authSPOnline; list.Config("SPOnlineSSO=true"); list.Config("FollowRedirects=1"); String cookie = list.Config("SPOnlineSecurityCookies"); ... list2.URL = "https://mycrm.sharepoint.com"; list2.Config("HttpCookies=" + cookie); list2.AuthScheme = SplistAuthSchemes.authNone; list2.Config("FollowRedirects=1"); list2.List = "MyCustomList"; list2.ListItems(); The default value is False. | |||||||
SPOnlineSTS: The URL of the online STS.This setting specifies the URL of the online STS. The default value is "https://login.microsoftonline.com/rst2.srf". | |||||||
SPOnlineADFSAuthScheme: The HTTP authentication scheme used when working with SSO.This setting controls the HTTP authentication scheme used when connecting to SharePoint online using SSO.
This is only applicable if SPOnlineSSO is set to True. Possible values are:
| |||||||
SSODomain: Specifies the federation domain configured in Office 365.SSODomain should be set to "OneLogin" when authenticating SharePoint Online via Office 365 through OneLogin Single Sign-On. | |||||||
UseSOAP: Whether to use SOAP or RPC calls for SharePoint operations.SharePoint supports two methods for performing actions on the SharePoint server called RPC and SOAP. Setting this configuration option to "true" will cause the component to issue SOAP requests. When set to "false" RPC requests are used. The default is "false". This configuration option is currently only effective for the CheckIn and CheckOut requests. | |||||||
VersionURL: Used to retrieve a specific past version of a document from SharePoint.A previous version of the file can be retrieved by specifying this configuration setting prior to calling the Get method.
This should be set to a valid version URL, which can be obtained using the ListVersions method.
Note: When this configuration setting is specified, the parameter passed to the Get method is ignored. After the file is retrieved, the VersionURL value is cleared. | |||||||
ViewID: The GUID of a view to use when listing documents.This setting may be set to the GUID of a view associated with this document library. When specified the view will be applied when returning results from List. This provides an easy way to determine which fields will be returned. | |||||||
EncryptionIV: The initialization vector to be used for encryption/decryption.When encrypting or decrypting a file this may be set this to the initialization vector.
Normally the control will derive this value using the value specified in EncryptionPassword, however
if a specific value is required it may be set here instead.
This setting accepts a hex encoded value. | |||||||
EncryptionKey: The key to use during encryption/decryption.When encrypting or decrypting a file this may be set this to the key.
Normally the control will derive this value using the value specified in EncryptionPassword, however
if a specific value is required it may be set here instead.
This setting accepts a hex encoded value. |
XML Configuration Settings
ParseCustomResponse: Whether to automatically parse the response from the SendCustomRequest() method.If the SharePoint site uses SOAP for its communication protocol, this configuration option can be set to "true" to automatically parse the SOAP response.
When this configuration option is set to "true" the control will automatically parse the SOAP response from the SharePoint server and the XML configuration options below can be used to navigate the XML structure of the response. This configuration option should be set to "true" only if the SharePoint site uses the SOAP protocol for communication. This configuration option will not function for the RPC protocol. The default value is "false". | |||||||||||||||||||||
XPath: Provides a way to point to a specific element in the returned XML response.XPath implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents.
The path is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location.
The following are possible values for an element accessor:
| |||||||||||||||||||||
XText: The text of the current element.The current element is specified in the XPath configuration option.
This configuration option is read-only. | |||||||||||||||||||||
XElement: The name of the current element.The current element is specified via the XPath configuration option.

The current element is specified via the XPath configuration option. This configuration option is read-only. | |||||||||||||||||||||
XAttributesPrefix[x]: The attribute prefix.Provides the prefix of the x'th attribute in the collection of attributes for the current element.
If the attribute does not have a prefix, this will return an empty string.
The current element is specified via the XPath configuration option. This configuration option is read-only. | |||||||||||||||||||||
XChildrenCount: The number of child elements of the current element.The number of child attributes of the current element. The XChildren configuration options will be indexed from 0 to XChildrenCount-1.
The current element is specified via the XPath configuration option. This configuration option is read-only. | |||||||||||||||||||||

element does not have a prefix, an empty string is returned.
The current element is specified via the XPath configuration option. This configuration option is read-only. |
HTTP Configuration Settings
AcceptEncoding: Used to tell the server which types of content encodings the client supports.When AllowHTTPCompression is true, the control adds an "Accept-Encoding: " header to the request being sent to the server. By default, this header's value is "gzip, deflate". This config allows you to change the value of the "Accept-Encoding" header. NOTE: The control only supports gzip and deflate decompression algorithms. | |
AllowHTTPCompression: This property enables HTTP compression for receiving data.This is the same as the AllowHTTPCompression property. This setting is exposed here for use by controls that inherit from HTTP. | |
AllowIdenticalRedirectURL: Allow redirects to the same URL.By default the control does not allow redirects to the same URL to avoid redirect loops. In some cases the server may intentionally redirect the client back to the same URL. In that case this setting may be set to True to allow the redirect to be followed. The default value is False. | |
Append: Whether to append data to LocalFile.This setting determines whether data is appended when writing to LocalFile. When set to True downloaded data will be appended to LocalFile. This may be used in conjunction with Range to resume a failed download. This is only applicable when LocalFile is set. The default value is False. | |
Authorization: The Authorization string to be sent to the server.
If the Authorization property contains a non-empty string,
an Authorization HTTP request header is added to the
request. This header conveys Authorization information to the
server.
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]". | |
BytesTransferred: Contains the number of bytes transferred in the response data. Returns the raw number of bytes from the HTTP response data, prior to the component processing the data, whether it is chunked and/or compressed. This returns the same value as the Transfer event, by BytesTransferred. | |
EncodeURL: If set to true the URL will be encoded by the control.The default value is false. If set to true the URL passed to the control will be URL encoded. | |
FollowRedirects: Determines what happens when the server issues a redirect.This option 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 1 (always), the new URL for the object is retrieved automatically every time.
If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same, otherwise the control fails with an error. Note that following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for 'GET' or 'HEAD' requests. Other methods could potentially change the conditions of the initial request and create security vulnerabilities. Furthermore, if either the new URL server and port are different than the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case 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 0 (Never). In this case, redirects are never followed, and the control fails with an error instead. Valid options are:
| |
GetOn302Redirect: If set to true the control will perform a GET on the new location.The default value is false. If set to true the control will perform a GET on the new location. Otherwise it will use the same HTTP method again. | |
HTTPVersion: The version of HTTP used by the control. Possible values include "1.0", and "1.1". The default is "1.1". | |
IfModifiedSince: A date determining the maximum age of the desired document.This is the same as the IfModifiedSince property. This setting is exposed here for use by controls that inherit from HTTP. | |
KeepAlive: Determines whether the HTTP connection is closed after completion of the request.If true, the component will not send the 'Connection: Close' header. The absence of the Connection header indicates to the server
that HTTP persistent connections should be used if supported. Note that not all server support persistent connections. You may
also explicitly add the Keep-Alive header to the request headers by setting OtherHeaders to 'Connection: Keep-Alive'.
If false, the connection will be closed immediately after the server response is received.
The default value for KeepAlive is false. | |
MaxRedirectAttempts: Limits the number of redirects that are followed in a request.When FollowRedirects is set to any value besides frNever the control will follow redirects until this maximum number of redirect attempts are made. The default value is 20. | |
OtherHeaders: Other headers as determined by the user (optional).This configuration option can be set to a string of headers to be appended to the HTTP request headers.
The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF (Chr$(13) & Chr$(10)) . Use this configuration option with caution. If this configuration option contains invalid headers, HTTP requests may fail. This configuration option is useful for extending the functionality of the control beyond what is provided. | |
ProxyAuthorization: The authorization string to be sent to the proxy server.Similar to the Authorization config, but for proxy authorization. If this config contains a non-empty string, a Proxy-Authorization HTTP request header is added to the request. This header conveys proxy authorization information to the server. If ProxyUser and ProxyPassword are specified, this value is calculated using the algorithm specified by ProxyAuthScheme. | |
ProxyAuthScheme: The authorization scheme to be used for the proxy.This is the same as ProxyAuthScheme. This setting is provided for use by controls that do not directly expose Proxy properties. | |
ProxyPassword: A password if authentication is to be used for the proxy.This is the same as ProxyPassword. This setting is provided for use by controls that do not directly expose Proxy properties. | |
ProxyPort: Port for the proxy server (default 80).This is the same as ProxyPort. This setting is provided for use by controls that do not directly expose Proxy properties. | |
ProxyServer: Name or IP address of a proxy server (optional).This is the same as ProxyServer. This setting is provided for use by controls that do not directly expose Proxy properties. | |
ProxyUser: A user name if authentication is to be used for the proxy.This is the same as ProxyUser. This setting is provided for use by controls that do not directly expose Proxy properties. | |
TransferredDataLimit: The maximum number of incoming bytes to be stored by the control.If TransferredDataLimit is set to 0 (default), no limits are imposed. Otherwise this reflects the maximum number of incoming bytes that can be stored by the control. | |
TransferredHeaders: The full set of headers as received from the server.This configuration setting returns the complete set of raw headers as received from the server. | |
UseChunkedEncoding: Enables or Disables HTTP chunked encoding for transfers.
If UseChunkedEncoding is set to true, the control will use HTTP chunked encoding when posting if possible.
HTTP chunked encoding allows large files to be sent in chunks instead of all at once.
If set to false, the control will not use HTTP chunked encoding. The default value is false.
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding. | |
ChunkSize: Specifies the chunk size in bytes when using chunked encoding.This is only applicable when UseChunkedEncoding is true. This setting specifies the chunk size in bytes to be used when posting data. The default value is 16384. | |
UserAgent: Information about the user agent (browser).This is the value supplied in the HTTP User-Agent header. The default
setting is "/n software IPWorks HTTP/S Component - www.nsoftware.com".
Override the default with the name and version of your software. | |
KerberosSPN: The Service Principal Name for the Kerberos Domain Controller. If the Service Principal Name on the Kerberos Domain Controller is not the same as the URL that you are authenticating to, the Service Principal Name should be set here. |
IPPort Configuration Settings
ConnectionTimeout: Sets a separate timeout value for establishing a connection.When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the control will use Timeout for establishing a connection and transmitting/receiving data. | |||||||||
FirewallAutoDetect: Tells the control whether or not to automatically detect and use firewall system settings, if available.This is the same as FirewallAutoDetect. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
FirewallHost: Name or IP address of firewall (optional).If a FirewallHost is given, requested connections will be authenticated through the specified firewall
when connecting.
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned. NOTE: This is the same as FirewallHost. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
FirewallPassword: Password to be used if authentication is to be used when connecting through the firewall.If FirewallHost is specified, the FirewallUser and FirewallPassword settings
are used to connect and authenticate to the given firewall. If the authentication fails, the control fails with an error.
NOTE: This is the same as FirewallPassword. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
FirewallPort: The TCP port for the FirewallHost;.Note that the FirewallPort is set automatically when FirewallType is set to a valid value.
NOTE: This is the same as FirewallPort. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
FirewallType: Determines the type of firewall to connect through.The appropriate values are as follows:
NOTE: This is the same as FirewallType. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
FirewallUser: A user name if authentication is to be used connecting through a firewall.If the FirewallHost is specified, the FirewallUser and FirewallPassword
settings are used to connect and authenticate to the Firewall. If the authentication fails, the control fails with an error.
NOTE: This is the same as FirewallUser. This setting is provided for use by controls that do not directly expose Firewall properties. | |||||||||
KeepAliveTime: The inactivity time in milliseconds before a TCP keep-alive packet is sent.When set, TCPKeepAlive will automatically be set to true.
By default the operating system will determine the
time a connection is idle before a TCP keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many
cases a shorter interval is more useful. Set this value to the desired interval in milliseconds.
Note: This value is not applicable in Java. | |||||||||
KeepAliveInterval: The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.When set, TCPKeepAlive will automatically be set to true.
A TCP keep-alive packet will be sent after a period of inactivity as
defined by KeepAliveTime. If no acknowledgement is received from the remote host the keep-alive packet
will be re-sent. This setting specifies the interval at which the successive keep-alive packets are sent in milliseconds.
This system default if this value is not specified here is 1 second.
Note: This value is not applicable in Java or MAC. | |||||||||
Linger: When set to True, connections are terminated gracefully.This property controls how a connection is closed. The default is True.
In the case that Linger is True (default), there are two scenarios for determining how long the connection will linger. The first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP protocol timeout expires. In the second scenario, LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection. The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data is sent (even after your application closes). Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (by a client acknowledgment, for example), setting this property to False might be the appropriate course of action. | |||||||||
LingerTime: Time in seconds to have the connection linger. LingerTime is the time, in seconds, to leave the socket connection linger. This value is 0 by default, which means it will use the default IP protocol timeout. | |||||||||
LocalHost: The name of the local host through which connections are initiated or accepted.
The LocalHost setting 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 multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface. If the control is connected, the LocalHost setting 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 multi-homed hosts (machines with more than one IP interface). | |||||||||
LocalPort: The TCP port in the local host where the control binds.
This must be set before a connection is
attempted. It instructs the control to bind to a specific
port (or communication endpoint) in the local machine.
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established. LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error. This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems. | |||||||||
MaxLineLength: The maximum amount of data to accumulate when no EOL is found.MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL
string.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset. If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset. The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes. The maximum value is 65536 bytes. | |||||||||
MaxTransferRate: The transfer rate limit in bytes per second.This setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default this is not set and there is no limit. | |||||||||
RecordLength: The length of received data records.If set to a positive value, this setting defines the length of data records to be received. The control will accumulate data
until RecordLength is reached and only then fire the DataIn event with data of length RecordLength.
This allows data to be received as records of known length. This value can be changed at any time, including within the DataIn event.
The default value is 0, meaning this setting is not used. | |||||||||
TCPKeepAlive: Determines whether or not the keep alive socket option is enabled.If set to true, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically
to maintain the connection. Set KeepAliveTime and KeepAliveInterval to
configure the timing of the keep-alive packets.
Note: This value is not applicable in Java. | |||||||||
UseIPv6: Whether to use IPv6.When set to 0 (default), the control will use IPv4 exclusively.
When set to 1, the control will use IPv6 exclusively. To instruct the control to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0.
Possible values are:
| |||||||||
TcpNoDelay: Whether or not to delay when sending packets.
When true, the socket will send all data that is ready to send at once. When
false, the socket will send smaller buffered packets of data at small intervals.
This is known as the Nagle algorithm.
By default, this config is set to false. |
SSL Configuration Settings
ReuseSSLSession: Determines if the SSL session is reused.
If set to true, the component will reuse the context if and only if the following criteria are met:
| |||||||||||||||||||||||||
SSLCipherStrength: The minimum cipher strength used for bulk encryption.
This minimum cipher strength largely dependent on the security modules installed
on the system. If the cipher strength specified is not supported,
an error will be returned when connections are initiated.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event. Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application. When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting. | |||||||||||||||||||||||||
SSLEnabledProtocols: Used to enable/disable the supported security protocols.Used to enable/disable the supported security protocols.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting. TLS 1.1 and TLS1.2 support are only available starting with Windows 7. | |||||||||||||||||||||||||
SSLProvider: The name of the security provider to use.
Change this setting to use security providers other than the system default.
Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application. The special value "*" (default) picks the default SSL provider defined in the system. Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed. | |||||||||||||||||||||||||
SSLSecurityFlags: Flags that control certificate verification.The following flags are defined (specified in hexadecimal
notation). They can be or-ed together to exclude multiple
conditions:
This functionality is currently not available when the provider is OpenSSL. | |||||||||||||||||||||||||
OpenSSLCADir: The path to a directory containing CA certificates.This functionality is available only when the provider is OpenSSL.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. | |||||||||||||||||||||||||
OpenSSLCAFile: Name of the file containing the list of CA's trusted by your application.
This functionality is available only when the provider is OpenSSL.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by -----BEGIN CERTIFICATE----- ... (CA certificate in base64 encoding) ... -----END CERTIFICATE----- sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details. | |||||||||||||||||||||||||
OpenSSLCipherList: A string that controls the ciphers to be used by SSL.
This functionality is available only when the provider is OpenSSL. The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH". | |||||||||||||||||||||||||
OpenSSLPrngSeedData: The data to seed the pseudo random number generator (PRNG).
This functionality is available only when the provider is OpenSSL.
By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG. |
Socket Configuration Settings
AbsoluteTimeout: Determines whether timeouts are inactivity timeouts or absolute timeouts.If AbsoluteTimeout is set to True, any method which does not complete within Timeout seconds
will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.
Note: This option is not valid for UDP ports. | |
FirewallData: Used to send extra data to the firewall.When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g. headers for custom authentication schemes). | |
InBufferSize: The size in bytes of the incoming queue of the socket.
This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be receiving. Increasing the value of the
InBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small. | |
OutBufferSize: The size in bytes of the outgoing queue of the socket.This is the size of an internal queue in the TCP/IP stack.
You can increase or decrease its size depending on the amount
of data that you will be sending. Increasing the value of the
OutBufferSize setting can provide significant improvements in
performance in some cases.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small. |
Base Configuration Settings
CodePage: The system code page used for Unicode to Multibyte translations.
The default code page is the Active Code Page (0).
The following is a list of valid code page identifiers:
