You can use the DDETerminate statement to close a specified dynamic data exchange (DDE) channel.
For example, if you have opened a DDE channel to transfer data between Microsoft Excel and Microsoft Access, you can use the DDETerminate statement to close that channel once the transfer is complete.
DDETerminate channum
The argument channum specifies the channel number to close. It refers to a channel opened by the DDEInitiate function. An error occurs if channum isn’t an integer corresponding to an open channel.
Once a channel is closed, any subsequent DDE functions or statements performed on that channel cause an error.
The DDETerminate statement has no effect on active DDE link expressions in fields on forms or reports.
Tip If you need to manipulate another application’s objects from Microsoft Access, you may want to consider using OLE Automation.
