The CreateStatusWindow function calls the CreateWindow function to create the window. It passes the parameters to CreateWindow without modification and sets the position, width, and height parameters to default values.
The CreateWindowEx function creates an overlapped, pop-up, or child window with an extended window style; otherwise, this function is identical to the CreateWindow function. For more information about creating a window and for full descriptions of the other parameters of CreateWindowEx, see CreateWindow.
