SAM_DDE_DataChange is sent to all objects in a DDE client application. It is sent when a DDE server has sent data to the client. When a DDE server sends an item to the client, the data appears automatically in the window that the client specified in SalDDEStartSession. The client application does not need to perform any action to receive the data. However, if the client application wants to know when the server sends an item, it can process the SAM_DDE_DataChange message. Note that SAM_DDE_DataChange is sent after the server sends the data to the client. Message Variables hWndForm Handle of a top-level window. hWndItem Object handle. wParam Unused. IParam Unused. Example Multiline Field: mlString1 ... Message Actions On SAM_DDE_DataChange Set dfStatus1 = 'Server data changed'
