Any application that adds or removes fonts from the system font table should notify other applications of the change by sending a WM_FONTCHANGE message to all top-level windows in the operating system (OS). The application should send this message by calling the SendMessage function and setting the hwnd parameter to HWND_BROADCAST.
When an application no longer needs a font resource that the application loaded by calling the AddFontResource function, the application must remove the resource by calling the RemoveFontResource function.
Windows CE 2.0 and later support systems that use either TrueType or raster fonts, but not both. The OEM chooses the font type at system design time, and applications cannot change the font type.
AddFontResource can add raster fonts if the GDI raster font component is built into the system, or TrueType fonts if the GDI TrueType font component is built into the system.
Note that AddFontResource will not work for raster fonts if the GDI TrueType font component is added to the system by the OEM, and will not work for TrueType fonts if the GDI raster font component is added to the system by the OEM.
Windows CE 1.0 and 1.01 support only raster fonts.
