DDEExecute Method [Access 2003 VBA Language Reference]

You can use the DDEExecute statement to send a command from a client application to a server application over an open dynamic data exchange (DDE) channel.

expression.DDEExecute(ChanNum, Command)

expression Required. An expression that returns one of the objects in the Applies To list.

ChanNum  Required Variant. A channel number, the long integer returned by the DDEInitiate function.

Command  Required String. A string expression specifying a command recognized by the server application. Check the server application's documentation for a list of these commands.


For example, suppose you've opened a DDE channel in Microsoft Access to transfer text data from a Microsoft Excel spreadsheet into a Microsoft Access database. Use the DDEExecute statement to send the New command to Microsoft Excel to specify that you wish to open a new spreadsheet. In this example, Microsoft Access acts as the client application, and Microsoft Excel acts as the server application.

The value of the command argument depends on the application and topic specified when the channel indicated by the channum argument is opened. An error occurs if the channum argument isn't an integer corresponding to an open channel or if the other application can't carry out the specified command.

From Visual Basic, you can use the DDEExecute statement only to send commands to another application. For information on sending commands to Microsoft Access from another application, see Use Microsoft Access as a DDE Server .
