PRB: Windows REQUEST Function Not Working With Excel

Last reviewed: November 2, 1995
Article ID: Q26234

The information in this article applies to:

Microsoft Windows Software Development Kit (SDK) for Windows versions 3.0 and 3.1

Microsoft Win32 Application Programming Interface (API) included with:

    - Microsoft Windows NT versions 3.5 and 3.51
    - Microsoft Windows 95 version 4.0

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.
