Problem with VS.NET 2003I'm having a problem with a VB.NET project that I'm building in VS.NET 2003 (7.1.3088). As my project has increased in size (the executable is now about 2.5MB), I am experiencing a lot of instability in the IDE. I have been working on this project for about 6 months now and have only recently started experiencing these problems. The first thing that I noticed was that when switching from the code view to the designer view, more than 50% of the time I get an error saying Object Reference not set to an instance of an object. I have to close the designer view, then re-open it, and everything is fine. This is quite annoying, but as I'm almost finished with the project, I just dealt with it. Well, the problems have moved up to a new level! Now, after I receive this message, close and re-open the designer, there are controls missing! The code for the controls is still there, but the control itself is missing from the form. If I try to re-add the control (using the same name), I get an error saying that an object with that name already exists (which, in code it does, but on the form it doesn't). So, I have to go to the code, remove the references to the control, then go back to the form and re-add it. I thought this was a one time occurance. I lost about 15 controls. But, as I was adding them back (switching back and forth between code view and design view), I got the same error message. I closed the designer, re-opened it, and the controls that I had just added, plus 3 more were missing!! I'm running on a dual P4 (3GHz) machine, with 2GB RAM and 400GB of disk space. I've de-fragged everything, shutdown, restart, and even sweet-talked my computer a bit, but nothing seems to help. I'm running McAfee AV and Firewall, and I regualrly check for Adware/Malware, etc. I don't know exactly how many controls I'm actually using in the project, but to say the least, it's a large project. Is there any limitation to the number of controls / forms / lines of code / etc. in a VB.NET project? Has anyone experienced this before? Any suggestions would be greatly appreciated!! I don't want to do any more work on the project, as I don't want to lose any more controls!! TIA Lee Hi,
Try reinstalling vs.net and the dot net framework 1.1 service pack 1.

I actually expected at least one response suggesting a re-install. It's on my list of things to try. And it's not really a big deal to do it. But, if it solves the problem, I'd like to know why. As I mentioned, I've been working on this app for several months. I have installed new software, but nothing recently. I work on this app 7 days a week, close to 16 hours a day, and I haven't installed anything new in the past 24-48 hours. I'm curious as to how an installed software package (like vs.net or the framework) could become somewhat corrupted and require an re-install if nothing else has changed on the computer.

In addition to Ken's suggestion. I think you may try to copy the project on another fine machine to see if the project is corrupted. Also I think you may try to create a new blank project and add the file ino the project to see if helps. Based on my experience, sometime the antivirus software or improper shut down machine/IDE may have influence, just a guess. If you want to know the root cause, I think you may need to contact MSPSS which will do the dump analysis or live debugging. If you still have any concern, please feel free to post here.

I ended up deleteing the project file and created a new one then reimported all my files. After that it ran in debug in a less than a minute. I have had the 'missing controls' problem both in VS2002 and VS2003
what happens is that for some reason the section of code that assigns the control to its parent (in the 'Windows Forms designer' section gets dropped, you can just re add it in there. I do not know the reason for it, but once it happens for a given form it is likely to reoccur. The only way to reduce the likelihood of it happening is to close the form as soon as you have made any changes to it - never leave it open - as it opens when a form is open in the designer. hth guy Show quoteHide quote "lgbjr" wrote: > Hi All, > > I'm having a problem with a VB.NET project that I'm building in VS.NET 2003 > (7.1.3088).
