STYLE styleThe STYLE statement defines the window style of the dialog box. The window style specifies whether the box is a pop-up or a child window. The default style has the following attributes: WS_POPUP, WS_BORDER, and WS_SYSMENU.
style
Specifies the window style. This parameter takes an integer value or predefined name. The following lists the predefined styles:
| Style | Meaning |
| DS_LOCALEDIT | Specifies that edit controls in the dialog box will use memory in the application's data segment. By default, all edit controls in dialog boxes use memory outside the application's data segment. This feature can be suppressed by adding the DS_LOCALEDIT flag to the STYLE command for the dialog box. If this flag is not used, EM_GETHANDLE and EM_SETHANDLE messages must not be used since the storage for the control is not in the application's data segment. This feature does not affect edit controls created outside of dialog boxes. |
| DS_MODALFRAME | Creates a dialog box with a modal dialog box frame that can be combined with a title bar and System menu by specifying the WS_CAPTION and WS_SYSMENU styles. |
| DS_NOIDLEMSG | Suppresses WM_ENTERIDLE messages that Windows would otherwise send to the owner of the dialog box while the dialog box is displayed. |
| DS_SYSMODAL | Creates a system-modal dialog box. |
| WS_BORDER | Creates a window that has a border. |
| WS_CAPTION | Creates a window that has a title bar (implies the WS_BORDER style). |
| WS_CHILD | Creates a child window. It cannot be used with the WS_POPUP style. |
| WS_CHILDWINDOW | Creates a child window that has the WS_CHILD style. |
| WS_CLIPCHILDREN | Excludes the area occupied by child windows when drawing within the parent window. Used when creating the parent window. |
| WS_CLIPSIBLINGS | Clips child windows relative to each other; that is, when a particular child window receives a WM_PAINT message, this style clips all other top-level child windows out of the region of the child window to be updated. (If the WS_CLIPSIBLINGS style is not given and child windows overlap, it is possible, when drawing in the client area of a child window, to draw in the client area of a neighboring child window.) For use with the WS_CHILD style only. |
| WS_DISABLED | Creates a window that is initially disabled. |
| WS_DLGFRAME | Creates a window with a modal dialog box frame but no title. |
| WS_GROUP | Specifies the first control of a group of controls in which the user can move from one control to the next by using the arrow keys. All controls defined with the WS_GROUP style after the first control belong to the same group. The next control with the WS_GROUP style ends the style group and starts the next group (that is, one group ends where the next begins). This style is valid only for controls. |
| WS_HSCROLL | Creates a window that has a horizontal scroll bar. |
| WS_ICONIC | Creates a window that is initially iconic. For use with the WS_OVERLAPPED style only. |
| WS_MAXIMIZE | Creates a window of maximum size. |
| WS_MAXIMIZEBOX | Creates a window that has a Maximize box. |
| WS_MINIMIZE | Creates a window of minimum size. |
| WS_MINIMIZEBOX | Creates a window that has a Minimize box. |
| WS_OVERLAPPED | Creates an overlapped window. An overlapped window has a caption and a border. |
| WS_OVERLAPPEDWINDOW | Creates an overlapped window having the WS_OVERLAPPED, WS_CAPTION, WS_SYSMENU, WS_THICKFRAME, WS_MINIMIZEBOX, and WS_MAXIMIZEBOX styles. |
| WS_POPUP | Creates a pop-up window. It cannot be used with the WS_CHILD style. |
| WS_POPUPWINDOW | Creates a pop-up window that has the WS_POPUP, WS_BORDER, and WS_SYSMENU styles. The WS_CAPTION style must be combined with the WS_POPUPWINDOW style to make the System menu visible. |
| WS_SIZEBOX | Creates a window that has a size box. Used only for windows with a title bar or with vertical and horizontal scroll bars. |
| WS_SYSMENU | Creates a window that has a System-menu box in its title bar. Used only for windows with title bars. If used with a child window, this style creates a Close box instead of a System-menu box. |
| WS_TABSTOP | Specifies one of any number of controls through which the user can move by using the TAB key. The TAB key moves the user to the next control specified by the WS_TABSTOP style. This style is valid only for controls. |
| WS_THICKFRAME | Creates a window with a thick frame that can be used to size the window. |
| WS_VISIBLE | Creates a window that is initially visible. This applies to overlapping and pop-up windows. For overlapping windows, the y parameter is used as a parameter for the ShowWindow function. |
| WS_VSCROLL | Creates a window that has a vertical scroll bar. |
