QuestionThe old DoEvents and UserControls Pin

Hi again.

I am curious about a problem I am having with DoEvents. Now, I know DoEvents() is old school, and was only included in vb6 because vb6 did not support threading, at least not without a lot of difficulty. But the problem I have, is that I have ported a vb6 program over to vb.Net and there were a fair amount of DoEvents() lines due to a bunch of loops. These DoEvents lines were necessary because I had a Pause button that needs to stop execution when the user desires it.

This worked OK in .Net, too...Until I included a TreeView usercontrol. Now, a fair amount of time is spent in the usercontrol since as the program scans folders, the TreeView is constantly updating to show the progress. In itself, that is a very inefficient way to show progress due to the amount of time processing the TreeView updates. But it looks rather cool as it progresses and I want to keep that look. The problem is that, I know that threading is the way to handle interruption of processing, but on the other hand, I just want this thing running as quickly as possible with the DoEvents lines...I can switch over to threading at some later date.

But no matter where I put the DoEvents lines, they do not let the Pause button Click event to fire. My question is, does entering a usercontrol cause DoEvents in the stack to get cleared out? Or does it simply disregard any DoEvents lines altogether, whether they are inside the user control or not?

Many thanks for any help on this. Smile | :)
