   [System::Runtime::InteropServices::DllImportAttribute("gdi32.dll")]
   static IntPtr GetStockObject( int fnObject );

public:
   void FromHfont_Example( PaintEventArgs^ e )
   {
      // Get a handle for a GDI font.
      IntPtr hFont = GetStockObject( 17 );

      // Create a Font object from hFont.
      System::Drawing::Font^ hfontFont = System::Drawing::Font::FromHfont( hFont );

      // Use hfontFont to draw text to the screen.
      e->Graphics->DrawString( "This font is from a GDI HFONT", hfontFont, Brushes::Black, 0, 0 );
   }
