Again? You can't delete an image that is in use. And it remains in use until you: - remove all references to it (as in ListBox.Items) - AND call Dispose() on that image And please show code snippets inside PRE tags. :)

So, what is the error message and what is the value of
makestr1when it gives the error? It would be easier to read if you use <pre> tags to formatsonic747 wrote:

Yikes, publishing someone's e-mail address is very naughty. He could still have removed it in his message, but he can't change yours though. It is *not* fair. :|

Yes, Luc, you're right. Thanks for pointing that out -- I've modified my message. I honestly wasn't paying attention.
