Remarks

An example of extended style:

Extended style code are as follows (note that all Windows SDK codes are shown):

Definition	Bitwise	Description
WS_EX_ACCEPTFILES	0x00000010	The window accepts drag-drop files.
WS_EX_APPWINDOW	0x00040000	Forces a top-level window onto the taskbar when the window is visible.
WS_EX_CLIENTEDGE	0x00000200	The window has a border with a sunken edge.
WS_EX_COMPOSITED	0x02000000	Paints all descendants of a window in bottom-to-top painting order using double-buffering. For more information, see Remarks. This cannot be used if the window has a class style of either CS_OWNDC or CS_CLASSDC.
WS_EX_CONTEXTHELP	0x00000400	The title bar of the window includes a question mark. When the user clicks the question mark, the cursor changes to a question mark with a pointer. If the user then clicks a child window, the child receives a WM_HELP message. WS_EX_CONTEXTHELP cannot be used with the WS_MAXIMIZEBOX or WS_MINIMIZEBOX styles.
WS_EX_CONTROLPARENT	0x00010000	The window itself contains child windows that should take part in dialog box navigation. If this style is specified, the dialog manager recurses into children of this window when performing navigation operations such as handling the Tab key, an arrow key, or a keyboard mnemonic.
WS_EX_DLGMODALFRAME	0x00000001	The window has a double border; the window can, optionally, be created with a title bar by specifying the WS_CAPTION style in the dwStyle parameter.
WS_EX_LAYERED	0x00080000	The window is a layered window. This style cannot be used if the window has a class style of either CS_OWNDC or CS_CLASSDC.
WS_EX_LAYOUTRTL	0x00400000	If the shell language is Hebrew, Arabic, or another language that supports reading order alignment, the horizontal origin of the window is on the right edge. Increasing horizontal values advance to the left.
WS_EX_LEFT	0x00000000	The window has generic left-aligned properties. This is the default.
WS_EX_LEFTSCROLLBAR	0x00004000	If the shell language is Hebrew, Arabic, or another language that supports reading order alignment, the vertical scrollbar (if present) is to the left of the client area. For other languages, the style is ignored.
WS_EX_LTRREADING	0x00000000	The window text is displayed using left-to-right reading-order properties. This is the default.
WS_EX_MDICHILD	0x00000040	The window is a MDI child window.
WS_EX_NOACTIVATE	0x08000000	A top-level window created with this style does not become the foreground window when the user clicks it. The system does not bring this window to the foreground when the user minimizes or closes the foreground window. The window does not appear on the taskbar by default. To force the window to appear on the taskbar, use the WS_EX_APPWINDOW style.
WS_EX_NOINHERITLAYOUT	0x00100000	The window does not pass its window layout to its child windows.
WS_EX_NOPARENTNOTIFY	0x00000004	The child window created with this style does not send the WM_PARENTNOTIFY message to its parent window when it is created or destroyed.
WS_EX_NOREDIRECTIONBITMAP	0x00200000	The window does not render to a redirection surface. This is for windows that do not have visible content or that use mechanisms other than surfaces to provide their visual.
WS_EX_OVERLAPPEDWINDOW	WS_EX_WINDOWEDGE WS_EX_CLIENTEDGE	The window is an overlapped window.
WS_EX_PALETTEWINDOW	WS_EX_WINDOWEDGE WS_EX_TOOLWINDOW WS_EX_TOPMOST	The window is palette window, which is a modeless dialog box that presents an array of commands.
WS_EX_RIGHT	0x00001000	The window has generic “right-aligned” properties. This depends on the window class. This style has an effect only if the shell language is Hebrew, Arabic, or another language that supports reading-order alignment; otherwise, the style is ignored. Using the WS_EX_RIGHT style for static or edit controls has the same effect as using the SS_RIGHT or ES_RIGHT style, respectively. Using this style with button controls has the same effect as using BS_RIGHT and BS_RIGHTBUTTON styles.
WS_EX_RIGHTSCROLLBAR	0x00000000	The vertical scrollbar (if present) is to the right of the client area. This is the default.
WS_EX_RTLREADING	0x00002000	If the shell language is Hebrew, Arabic, or another language that supports reading-order alignment, the window text is displayed using right-to-left reading-order properties. For other languages, the style is ignored.
WS_EX_STATICEDGE	0x00020000	The window has a three-dimensional border style intended to be used for items that do not accept user input.
WS_EX_TOOLWINDOW	0x00000080	The window is intended to be used as a floating toolbar. A tool window has a title bar that is shorter than a normal title bar, and the window title is drawn using a smaller font. A tool window does not appear in the taskbar or in the dialog that appears when the user presses *Alt+Tab*. If a tool window has a system menu, its icon is not displayed on the title bar. However, you can display the system menu by right-clicking or by typing Alt+Space.
WS_EX_TOPMOST	0x00000008	The window should be placed above all non-topmost windows and should stay above them, even when the window is deactivated.
WS_EX_TRANSPARENT	0x00000020	The window should not be painted until siblings beneath the window (that were created by the same thread) have been painted. The window appears transparent because the bits of underlying sibling windows have already been painted.
WS_EX_WINDOWEDGE	0x00000100	The window has a border with a raised edge.
