I'm trying to set up an auto-run program for a cd that I'm creating for a friend.  I'd like to be able to access outside applications, ie Windows Explorer off of buttons.  I'm not sure how to do this, seeing as how I haven't been programming in Delphi very long.

You can use WinExec('c:\...\ExeName',SW_SHOW);

This code will open windows explorer starting in Program Files. Change explore to open if you want views like the ones that appear when you double click My Computer on the desktop.

ShellExecute(Application.Handle,
                        PChar('explore'),
                        PChar('c:\program files'),
                        PChar(''),
                        PChar(''),
                        SW_SHOWDEFAULT);

Don't forget to add ShellApi to your uses clause.

Cheers,
Phil.

my other question with this is how can I detect where it's running from, for example I know in Java (the last language I was programming in) there's the command getDocumentBase() where you can retrieve the directory where the .java file is located.

Do you mean that you want to extract 'c:\mydir\' from 'c:\mydir\javafile.java'?
If so, use ExtractFilePath and add SysUtils to the uses clause.
