Personal Communications supports the DDE system topic so that a client application can connect to the system topic and retrieve information about Personal Communications and the status of the sessions that Personal Communications is managing.

The Get System SysItems function returns the list of data items available in the Personal Communications system topic. The client application sends the following message to get the system topic data items:

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

where:

cfFormat: Identifies the DDE format for the data item requested. The value used is CF_TEXT.
aSYSITEMS: Identifies SysItems as the data item requested.
