In Microsoft Excel, you can discover which of your currently open programs are capable of dynamic data exchange (DDE) by using the DDEInitiate method in a Microsoft Visual Basic for Applications macro.

You can display a DDE dialog box that lists all of the open programs and topics to which Excel can open a DDE channel.

TIP: You can then use the DDEExecute method to send commands to another program.
