call DDEExecute ( ConvID_IV, Command_SV, DataLength_IV, Status_IV )
•ConvID_IV is an integer value representing the conversation ID assigned by the DDE DLL.
•Command_SV is a string value representing the command that the server executes. The DDE protocol does not define the format of these commands, although the DDE protocol definition document does suggest a format. For more information, consult the documentation for the particular server for which the commands are intended.
•DataLength_IV is a string value representing the length of the command.
•Status_IV must be 0.
