Window Styles The following are the window styles. After the window has been created, these styles cannot be modified, except as noted. WS_BORDER 0x00800000L The window has a thin-line border. WS_CAPTION 0x00C00000L The window has a title bar (includes the WS_BORDER style). WS_CHILD 0x40000000L The window is a child window. A window with this style cannot have a menu bar. This style cannot be used with the WS_POPUP style. WS_CHILDWINDOW 0x40000000L Same as the WS_CHILD style. WS_CLIPCHILDREN 0x02000000L Excludes the area occupied by child windows when drawing occurs within the parent window. This style is used when creating the parent window. WS_CLIPSIBLINGS 0x04000000L Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, the WS_CLIPSIBLINGS style clips all other overlapping child windows out of the region of the child window to be updated. If WS_CLIPSIBLINGS is not specified and child windows overlap, it is possible, when drawing within the client area of a child window, to draw within the client area of a neighboring child window. WS_DISABLED 0x08000000L The window is initially disabled. A disabled window cannot receive input from the user. To change this after a window has been created, use the EnableWindow function. WS_DLGFRAME 0x00400000L The window has a border of a style typically used with dialog boxes. A window with this style cannot have a title bar. WS_GROUP 0x00020000L The window is the first control of a group of controls. The group consists of this first control and all controls defined after it, up to the next control with the WS_GROUP style. The first control in each group usually has the WS_TABSTOP style so that the user can move from group to group. The user can subsequently change the keyboard focus from one control in the group to the next control in the group by using the direction keys. You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use the SetWindowLong function. WS_HSCROLL 0x00100000L The window has a horizontal scroll bar. WS_ICONIC 0x20000000L The window is initially minimized. Same as the WS_MINIMIZE style. WS_MAXIMIZE 0x01000000L The window is initially maximized. WS_MAXIMIZEBOX 0x00010000L The window has a maximize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. WS_MINIMIZE 0x20000000L The window is initially minimized. Same as the WS_ICONIC style. WS_MINIMIZEBOX 0x00020000L The window has a minimize button. Cannot be combined with the WS_EX_CONTEXTHELP style. The WS_SYSMENU style must also be specified. WS_OVERLAPPED 0x00000000L The window is an overlapped window. An overlapped window has a title bar and a border. Same as the WS_TILED style. WS_OVERLAPPEDWINDOW (WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX) The window is an overlapped window. Same as the WS_TILEDWINDOW style. WS_POPUP 0x80000000L The windows is a pop-up window. This style cannot be used with the WS_CHILD style. WS_POPUPWINDOW (WS_POPUP | WS_BORDER | WS_SYSMENU) The window is a pop-up window. The WS_CAPTION and WS_POPUPWINDOW styles must be combined to make the window menu visible. WS_SIZEBOX 0x00040000L The window has a sizing border. Same as the WS_THICKFRAME style. WS_SYSMENU 0x00080000L The window has a window menu on its title bar. The WS_CAPTION style must also be specified. WS_TABSTOP 0x00010000L The window is a control that can receive the keyboard focus when the user presses the TAB key. Pressing the TAB key changes the keyboard focus to the next control with the WS_TABSTOP style. You can turn this style on and off to change dialog box navigation. To change this style after a window has been created, use the SetWindowLong function. For user-created windows and modeless dialogs to work with tab stops, alter the message loop to call the IsDialogMessage function. WS_THICKFRAME 0x00040000L The window has a sizing border. Same as the WS_SIZEBOX style. WS_TILED 0x00000000L The window is an overlapped window. An overlapped window has a title bar and a border. Same as the WS_OVERLAPPED style. WS_TILEDWINDOW (WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_THICKFRAME | WS_MINIMIZEBOX | WS_MAXIMIZEBOX) The window is an overlapped window. Same as the WS_OVERLAPPEDWINDOW style. WS_VISIBLE 0x10000000L The window is initially visible. This style can be turned on and off by using the ShowWindow or SetWindowPos function. WS_VSCROLL 0x00200000L The window has a vertical scroll bar.

Henrik Haftmann 8/23/2012 Low 16 bits? When I look at all the windows, I find many with bits set in the low 16 bits, but none of the flags are defined for those bits. That is on Windows 7. What do these bits mean? Answer: Edit Control Styles (e.g. ES_CENTER = 0x0001L, ES_RIGHT = 0x0002L, ES_MULTILINE = 0x0004L, etc. declared in "winuser.h") details at: "http://msdn.microsoft.com/en-us/library/bb775464(v=vs.85)" Button Control Styles (e.g. BS_DEFPUSHBUTTON = 0x00000001L, BS_CHECKBOX = 0x00000002L, BS_AUTOCHECKBOX = 0x00000003L, etc. declared in "winuser.h") details at: "http://msdn.microsoft.com/en-us/library/bb775951(v=vs.85)" Static Control Styles (e.g. SS_CENTER = 0x00000001L, SS_RIGHT = 0x00000002L, SS_ICON = 0x00000003L, etc. declared in "winuser.h") details at: "http://msdn.microsoft.com/en-us/library/bb760773(v=vs.85)" Detail about these and other controls are at: "http://msdn.microsoft.com/en-us/library/bb773169(v=vs.85)". The appropriate header file is stated at each control's styles page in the Requirements section. Zdenek Velisek 7/1/2012 WS_CHILD prevents CS_DROPSHADOW If you're hoping to make a temporary popup control in your window and want to use CS_DROPSHADOW to reinforce the fleeting nature of the popup, you can't use it with WS_CHILD -- it just ignores CS_DROPSHADOW. You'll need to make your control be WS_POPUP and then position it where you want it when it opens. Thomas Lee 1/25/2012 No library tree node This page has no corresponding MSDN Library tree node. Consider adding one like for STATIC controls - see tag. ------------ If you are connected in other languages than English, This thing will be happen.

WS_EX_NOACTIVATE or WS_DISABLED tends to make the window inactivated, but on Windows XP, if you set a WS_VISIBLE(or any combination with that ) to CreateWindow[Ex]()'s dwStyle parameter, the window, however, looks as it is activated, but actually is not. So Don't set this flag at the very first, use ShowWindow() later to make it visible in this case. On Windows 7, no difference this flag is initially set or a ShowWindow() is called, the caption(title bar) is darker(meanwhile the window looks inactivated as well as it is). YumeYao 4/12/2010 Errors in WS_DLGFRAME and WS_SYSMENU styles "WS_DLGFRAME Creates a window that has a border of a style typically used with dialog boxes. A window with this style cannot have a title bar." This is wrong. If you create a window with just this style, you get a window with a caption and a border. "WS_SYSMENU Creates a window that has a window menu on its title bar. The WS_CAPTION style must also be specified." Again, if you create a window with just this style, WS_SYSMENU, you get a window with a caption and a border.
