18. Styles Common to All Classes
Base Window Styles
The following window styles are shared by all windows, regardless of their class. They generally describe the window's general appearance, although many of the styles apply best to non-control windows (particularly overlapped windows).
Styles

The window has a thin-line border.
WS_CAPTION
The window has a title bar.
WS_CHILD, WS_CHILDWINDOW
The window is a child window. These windows cannot have menu bars nor can have the WS_POPUP style.
WS_CLIPCHILDREN
For a parent window, exclude the areas occupied by child windows when drawing within the window (to avoid drawing on any child windows).

The window is maximized.
WS_MAXIMIZEBOX
The window has a maximize button. This cannot be used on windows having the WS_EX_CONTEXTHELP extended window style. The WS_SYSMENU window style must also be specified.

Constant Definitions
Below is a list of the extended window styles. The main difference between these and regular window styles is that these are specified as a separate value. (For example, a call to
CreateWindowEx takes one parameter for extended window styles and a second parameter for "regular" window styles.) These styles can be applied to any type of window, although many of them apply best to overlapped windows.
