ITsSbClientConnection::PutContext method (sbtsv.h)

  • Article

Can be used by plug-ins to store context information specific to the connection.

Syntax

HRESULT PutContext(
  [in]            BSTR    contextId,
  [in]            VARIANT context,
  [out, optional] VARIANT *existingContext
);

Parameters

[in] contextId

A BSTR variable that contains the context ID. We recommend using unique identifiers as context IDs to avoid collisions between plug-ins. A client connection object can be used by more than one plug-in.

[in] context

The context information to store.

[out, optional] existingContext

Existing context information for the supplied context ID, if any, is returned in this parameter. The existing information is overwritten.

Return value

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Plug-ins can use the client connection object to store context information that is specific to a connection request. This allows plug-ins to remain stateless and rely exclusively on state information stored by connection requests. Plug-ins that use this method can also register for connection request notifications. Contexts can be deleted upon receipt of CONNECTION_REQUEST_FAILED, CONNECTION_REQUEST_TIMEDOUT, or CONNECTION_REQUEST_SUCCEEDED notifications. These notifications indicate that the connection request is about to be deleted.
