| Dynamic data exchange (DDE) is an older technology that is not secure. If possible, use a more secure alternative to DDE, such as object linking and embedding (OLE). |
If it is successful, the DDEInitiate method returns the number of the open channel. All subsequent DDE functions use this number to specify the channel.
Example
This example initiates a DDE conversation with the System topic and opens the Microsoft Office Excel workbook Sales.xls. The example terminates the DDE channel, initiates a channel to Sales.xls, and then inserts text into cell R1C1.
