You need to pass Handle to display Messagebox on Screen, You can use HWND WINAPI GetDesktopWindow(void); function to get the Handle of Desktop and pass this in MessageBox () function.
You can get more help from

GetDesktopWindoe retrieves a handle to the desktop window. The desktop window covers the entire screen. The desktop window is the area on top of which other windows are painted. So this will work for OpenGL as well.
