Not showing up

[vbgladiator]

Hey,

I have an application that is ran on several computers by the client. However, on some of them, the main window does not show up when started by either shortcut or by double clicking the executable itself. THey're running Windows 2000.

I haven't seen it or be able to reproduce it. They're telling me that the application is running in the background but is not visible on the screen. They see it in the task manager.

Any advice is appreciated,

Thanks,

Is it consuming resources?

[vbgladiator]

It's running as they can see it in Task Manager so I'm assuming that yes.

I had the same problem some time ago. Unfortunately, I don't remember exactly what the cause was, but I think it was some files on the user's computer that needed updating. You may want to make sure they have the latest run time files, mdac etc. I'll try to catch up with the guy that helped me solve and see if he remembers what the deal was.

Actually, it was some dll's I had not packaged with the program. I just made a new install package and made sure all required dll's were there.
Hope that helps

Hi,

Well, it works on 95% of the computers and not on 2. They're all Windows 2000 and all installed using the same setup package so I'm pretty all the required files are being installed. It worked until 1 day it just stopped appearing on the screen.

Thanks,

Sometimes VB's installer packages fails to properly register the DLLs and OCXs.



Try to regsvr32 them manually, or make a script to do it after installation.

Do you have any App.PrevInstance code in your program? If so it could be that you are not ending your program properly and the second time the program is run it finds and "restarts" the fragment process that is still running.
