SYMPTOMS

The REQUEST function does not work correctly with Excel. The request message is received, however, Excel does not process the WM_DDE_DATA message that is sent back.

RESOLUTION

The fResponse bit must also be set in the WM_DDE_DATA message (bit 12). This bit tells Excel that the data message is in reply to a REQUEST function and not an ADVISE function. If "lpddeup->fResponse=1" is added, the REQUEST function should work correctly.
