    Unhappy SetLayeredWindowAttributes not recognized!

    HI all,

    I am trying to use the function SetLayeredWindowAttributes() but unfortunately MSVC doesn't recognize it
    I use VC++v6.0 with Windows Server 2003 SP1 SDK installed.
    i have also include windows.h, user32.lib as defined in MSDN, but no hope.

    What could be the problem?

    SetLayeredWindowAttributes is defined in winuser.h inside a conditional statement. Define _WIN32_WINNT to be at least 0x0500 and it should work.

    You are welcome.
    Don't forget that layered windows only work on Windows 2000, XP or later.
