DDERequest Function

Microsoft Access Visual Basic

DDERequest(channum, item)

The DDERequest function has the following arguments.

Argument Description
channum A channel number, the integer returned by the DDEInitiate function.
item A string expression that's the name of a data item recognized by the application specified by the DDEInitiate function. Check the application's documentation for a list of possible items.

Remarks

The channum argument specifies the channel number of the desired DDE conversation, and the item argument identifies which data should be retrieved from the server application. The value of the item argument depends on the application and topic specified when the channel indicated by the channum argument is opened. For example, the item argument may be a range of cells in a Microsoft Excel spreadsheet.

The DDERequest function returns a Variant as a string containing the requested information if the request was successful.

The data is requested in alphanumeric text format. Graphics or text in any other format can't be transferred.

If the channum argument isn't an integer corresponding to an open channel, or if the data requested can't be transferred, a run-time error occurs.
