davelt99 Member Licensed User Longtime User Jan 22, 2013 #1 I'm placing ProgressDialogShow with message just before a number of layered Do While loops that perform some extensive calculations taking an average of 10 seconds. At the end of the loops I'm placing the ProgressDialogHide. My problem is that the dialog never appears unless I'm in debug mode and stop it at that line. It doesn't seem to be running asynchronously. Not sure what I'm doing wrong. Thank you

JonPM Well-Known Member Licensed User Longtime User Jan 23, 2013 #5 Erel, it seems that this issue comes up on occasion. Would it be cumbersome to combine the DoEvents logic with ProgressDialogShow behind the scenes? That way it is called automatically every time Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Jan 24, 2013 #6 Calling DoEvents once is not enough as the progress bar will only show as a static dialog. You need to call DoEvents inside your loop. I usually do something like: Code: Copy For i = 0 To 100000 'this is the original loop that is required for the task If i Mod 100 = 0 Then DoEvents ... Next Such logic cannot be added to ProgressDialogShow. Upvote 0
