VB6 program hangs until action is taken

[tammy104]

Hi All
I have a VB6 program that inconsistantly hangs at a specific point in the program. It will sit there forever until an action is taken like clicking the mouse in the program or someone even just hitting ctrl-alt-del. Then it resumes normally.

I foud a way to avoid the problem when I was troubleshooting and I was using a remote control program to view the system. When I am remotley viewing the system from another computer using pcanywhere it never hangs.

The problem happens on several OS and hardware types.

Any ideas ??
Thank you.

More information please:

a) Is your project a stand alone exe? If not, what is it?

b) If it is, then is the "StartUp Object" (in the "Project Properties") a form or a Sub Main (without a form)?

c) If it is a form, is it completing the form's Load and Activate events?

d) Describe the architecture of the "StartUp Object"

Cheers ... Greg.

Sounds like you are doing a lot of processing in a loop or two. Perhaps a DoEvents every so many iterations may help.

Good Luck

Check that you dont have any explicit SetFocus commands in there. I have seen this kind of behaviour when validation code keeps playing 'focus tennis' between input controls.
