WinApi AddClipboardFormatListener and WPARAM Value in Message/Getting the Format of the new Clipboard Content RRS feed

  • Domanda

  • Dear Community,

    MSDN says:

    https://docs.microsoft.com/de-de/windows/win32/dataxchg/wm-clipboardupdate?redirectedfrom=MSDN

    WPARAM and LPARAM must be 0 in the WM_CLIPBOARDUPDATE Message. Now I have made a Format Listener and I used Visual C++ Debugger. I realized that there is a value inside WPARAM.

    Is WPARAM unused or  is the description outdated?

    My second question is:

    The Clipboard can contain text, pictures and other data. How to find the best way to get the Format of the new clipboard data?

    Greetings
