Adding an icon to the Windows About dialog

Answer:

If you want to bring up the standard Windows 'About..' dialog box, then you can use 
ShellAbout() from the ShellAPI unit and customize the appearance by adding your own 
text, application name and an icon.

The downside to this technique is that it will say '(c) Microsoft' in the box.

The upside is that you see the registered user and some system parameters (free 
space..). It's a quick-and-dirty solution for an About-box.

2     Windows, ShellAPI;

4   procedure TForm1.About1Click(Sender: TObject);
5   begin
6     ShellAbout(Application.MainForm.Handle,
7       'Address Book Application',
8       'Version 1.23.3beta' + #13#10 +
9       'Compiled 2001-08-03 15:25:10',
10      Application.Icon.Handle);
