    Errors

    I tried to make my window trasparent using layers and look what compiler says


    F:\C\Trasnparent\MakeWindowTransparent.cpp(57) : error C2065: 'WS_EX_LAYERED' : undeclared identifier
    F:\C\Trasnparent\MakeWindowTransparent.cpp(67) : error C2065: 'LWA_COLORKEY' : undeclared identifier
    F:\C\Trasnparent\MakeWindowTransparent.cpp(67) : error C2065: 'LWA_ALPHA' : undeclared identifier


    I am using VC++ 6 under windows xp pro

    Time to download the new version of the SDK!

    If that will take too long you could always;

    Code:
    #define WS_EX_LAYERED           0x00080000
    #define LWA_COLORKEY            0x00000001
    #define LWA_ALPHA               0x00000002
    That should allow it to work

    Or you could try #define _WIN32_WINNT 0x0500 before #including <windows.h>

    You should still get up to date with the latest SDK as Fordy has recommended.
