About Controls

Controls, like other windows, each belong to a window class, either predefined or owner-defined. The window class and the corresponding window procedure define the properties of the control, its appearance, behavior, and purpose. An application can create controls individually by specifying the name of the window class when calling the CreateWindowEx function. An application can also direct the system to create controls for a dialog box by specifying the controls in the dialog box template.
