    ShowMessage(Format('%d Icons', [NumberOfIcons]));
    // Extract the first 5 icons
    
for i := 1 to do
    begin
      
// Extract an icon
      
icon.Handle := ExtractIcon(Handle, PChar(ExtrFileName), i);
      // Draw the icon on your form
      
DrawIcon(Form1.Canvas.Handle, 10, i * 40, icon.Handle);
