The style of the dialog box. This member can be a combination of window style values (such as WS_CAPTION and WS_SYSMENU) and dialog box style values (such as DS_CENTER).
If the style member includes the DS_SETFONT style, the header of the dialog box template contains additional data specifying the font to use for text in the client area and controls of the dialog box. The font data begins on the WORD boundary that follows the title array. The font data specifies a 16-bit point size value and a Unicode font name string. If possible, the system creates a font according to the specified values. Then the system sends a WM_SETFONT message to the dialog box and to each control to provide a handle to the font. If DS_SETFONT is not specified, the dialog box template does not include the font data.
The DS_SHELLFONT style is not supported in the DLGTEMPLATE header.
