把VC对话框设为半透明

在 OnInitDialog 中加入：

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); }
