[janine <ja...@cl...>]

I'm using Dev-C++ 4, and I really don't understand why I'm getting an,

"undefined reference to 'GetStockObject@4' " message? Below is how I've =
registered the class

//Register Main Window Class
    winclass.style =3D CS_HREDRAW|CS_VREDRAW;
    winclass.lpfnWndProc =3D FrameWinProc;
    winclass.cbClsExtra =3D 0;
    winclass.cbWndExtra =3D 0;
    winclass.hInstance =3D hInstance;
    winclass.hIcon =3D LoadIcon(NULL, IDI_APPLICATION);
    winclass.hCursor =3D LoadCursor(NULL, IDC_ARROW);
    winclass.hbrBackground =3D (HBRUSH)GetStockObject(WHITE_BRUSH);
    winclass.lpszMenuName =3D DefaultMenu;
    winclass.lpszClassName =3D FrameClass;

    if((RegisterClass(&winclass)) =3D=3D 0 )
        return 0;

Can anyone please help?
