refresh/redraw winForm 1

[cjburkha]

Hi, I have a simpl form, with one button on it. When you click the button, some things happen that take maybe 3 minutes. How can I return control to the form during this time?

That is, during this time, the form can't be moved, and I update a lable with a counter indicating progress, but if you click a different window and come back, the form is not redrawn.

Any ideas?

Thanks

CJB

Put your long-running process in it's own thread.

Be sure not to update the form from that other thread -- you can only touch a WinForm from the thread that created it.

Thanks Chip. I've never done multi-threads before, but I can figure it out with some help from Google.

Any suggestions on how to update the form then? I could have some timer that checks to see if the thread is still running, but I would like to display the iterations that the thread has completed.

thanks,

CJB

Thanks, I think I found all that I need, including calling the parent thread here
