I don't know if I am asking the question correctly, but I want to keep a program I use all the time in memory (running).

So instead of closing the program (main form), I would like to simply set it's visible =false. This is easily done and works.

Then on restart (I already know how to check to see if it is running) I would like to attach to it and make that running version's main form be visible again.

Since this happens on many programs it's probably easy, and I am using the wrong wording when I search for "How to attach..."

Thanks for your help.
