The AddFontResourceEx function adds the font resource from the specified file to the system. Fonts added with the AddFontResourceEx function can be marked as private and not enumerable.
int AddFontResourceExA( LPCSTR name, DWORD fl, PVOID res );
A pointer to a null-terminated character string that contains a valid font file name. This parameter can specify any of the following files.
To add a font whose information comes from several resource files, point lpszFileName to a string with the file names separated by a | --for example, abcxxxxx.pfm | abcxxxxx.pfb.
The characteristics of the font to be added to the system. This parameter can be one of the following values.
Reserved. Must be zero.
If the function succeeds, the return value specifies the number of fonts added.
If the function fails, the return value is zero. No extended error information is available.
This function allows a process to use fonts without allowing other processes access to the fonts.
When an application no longer needs a font resource it loaded by calling the AddFontResourceEx function, it must remove the resource by calling the RemoveFontResourceEx function.
This function installs the font only for the current session. When the system restarts, the font will not be present. To have the font installed even after restarting the system, the font must be listed in the registry.
A font listed in the registry and installed to a location other than the %windir%\fonts\ folder cannot be modified, deleted, or replaced as long as it is loaded in any session. In order to change one of these fonts, it must first be removed by calling RemoveFontResource, removed from the font registry (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts), and the system restarted. After restarting the system, the font will no longer be loaded and can be changed.
