The Get Partial Presentation Space function returns all or part of the session presentation space to the client.

Note: The client must set the start PS position and either the PS length or End of Field (EOF) flag by using the Set Presentation Space Service Condition function before using this function. If the EOF flag is set to PCS_EFFECTEOF, the function will return the entire field specified by the start PS position

The client sends the following command to get the presentation space.

PostMessage( hServerWnd,
             WM_DDE_REQUEST,
             hClientWnd,
             MAKELPARAM(cfFormat, aEPS) );

where:

cfFormat: Identifies the format for the presentation space. Valid values are CF_TEXT or CF_DSPTEXT. The structure of the presentation space, in these two formats, is shown below.
aEPS: Identifies the session presentation space as the item.
