Please note that for my situation, the Form must be mode less. I am starting to read about threads, but am hoping that you will have a faster solution.

Hello Viv,

Thank you very much for your reply.

What I am doing is indexing through a collection of classes, and each class has a property that tells me if a certain action/calibration is required. If so then I want to stop the loop, display the form corresponding to the action/calibration that is required and when finished, the form will close itself and the loop will continue. I know that this would be easy to achieve when using model forms, but what happens is that I have timer that monitors the state of the equipment and displays a message if there are any error conditions such as the serial connection being lost and I want the error message to be displayed immediately.

Maybe I don't need to use threads here?

That's about the best I can explain it, I hope this helps.

Thank you

Gary
