SetLayeredWindowAttributes not recognized!

[leojose]

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?

did u install the latest Platform SDK ?

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

Hey MarcG,

Your suggestion worked!


Thanks :)

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