    WM_COPYDATA

    Hi,

    I am trying to find if there is a structure in VB.NET that uses
    COPDATSTRUCT.
    In interfacing to an existing application, the application uses WM_COPYDATA
    message
    extensively, between applications.
    I was able to capture the message loop within a VB.Net application using
    WndProc() method,
    and was receiving message 74 for WM_COPYDATA message.
    The issue I am running into is that the internal message I am looking for is
    in the COPYDATASTRUCT
    dwData.
    So I am looking for a way to reference the message within the
    COPYDATASTRUCT from
    the WndProc() method.

    Example of C++ application...

    within message received function
Working...
