//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);
}
