[QUOTE="chemelli, post: 633746, member: 25221"] Dukus, I think you should also do a call to "SendMessage" to notify the OS that a new font is installed. Sample code: [CODE] Ret = FontInstall.AddFontResource(FontPath); Res = FontInstall.SendMessage(HWND_BROADCAST, WM_FONTCHANGE, 0, 0); Ret = FontInstall.WriteProfileString("fonts", FontName + " (TrueType)", FontFileName); [/CODE] function definition: [CODE] [DllImport("kernel32.dll", SetLastError=true)] static extern int WriteProfileString( string lpszSection, string lpszKeyName, string lpszString) ; [DllImport("user32.dll")] public static extern int SendMessage(int hWnd, // handle to destination window uint Msg, // message int wParam, // first message parameter int lParam // second message parameter ); [DllImport("gdi32")] public static extern int AddFontResource(string lpFileName); [/CODE] Simone EDIT: Const definition: [CODE] const int WM_FONTCHANGE = 0x001D; const int HWND_BROADCAST = 0xffff; [/CODE] [/QUOTE]
