透明窗口

在OnInitDialog()加入:
//加入WS_EX_LAYERED扩展属性
SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE,
GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000);
HINSTANCE hInst
= LoadLibrary("User32.DLL");
if(hInst)

{

typedef
BOOL (WINAPI *MYFUNC)(HWND,COLORREF,BYTE,DWORD);
MYFUNC
fun = NULL;
//取得SetLayeredWindowAttributes函数指针

fun=(MYFUNC)GetProcAddress(hInst,
"SetLayeredWindowAttributes");
if(fun)fun(this->GetSafeHwnd(),0,128,2);

FreeLibrary(hInst);

}
