ICommunicate ??

Yes indeed^_^ It's still on the server, but don't expect to much of it. It's merily an example on how interfaces can be usefull to grant access to certain functionality. Look in the post A.L. pointed and copy/paste the URL

Do you refer to the "Multiple forms windows applications" thread? If so, ICommunicate is the name of an interface made by mr. nobrainer in a sample zip file uploaded on his server. If it's still there, try and get it and you'll see what's it about. It's a very helpful sample for beginners.
