Thread: 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?

Chances are your Platform SDK is either out of date or you've installed it somewhere that Visual C++ isn't looking. Try searching your include directory for the function and seeing if it turns up or not.

Although it's preferable to set the macro value within your project settings/options.

Hi Ken,

Your suggestion worked!
actually i set the value within Project settings...

Thanks
