Several times per day, I have instances of this application that crash (seemingly at random, but always after being used for almost a day). I've searched and read many forums and even questions asked here on Stack Overflow about this particular problem. What I've determined is that this is related to a memory leak and usually points to either the handles exceeding 10,000 or the objects exceeding the limit. I've downloaded the memory pro filer and have used it to locate and fix several memory leaks in the program but that hasn't seemed to slow down the daily crash count. My program uses a global error catcher to log these events and store information about them in the database. I've now got about 2 months worth of data but the error message doesn't really help point me in any kind of direction. I've recently added the ability for this global error catcher to log the handles that the application has and so far it has been far below the 10,000 handle threshold. Usually it is under 1,000. Long story short, my question is this. Is there some way to log the GDI object count so I can determine if that is causing my program to crash? Are there other 'objects' that might be causing the memory leak and crash besides these two and can I log those some how? I've tried reading as much as I can and I just can't get a good grasp on this so I appreciate any direction you can give me. It seems like these types of problems plague a lot of programs. Hopefully someone can help me and this can help others in the future. A little more information about my program and environment. It mostly runs on Windows 7 64 bit machines (although some vista and XP machines are present), it is running on .NET 4.0 framework. The project consists of a few hundred forms, classes, and custom controls (built specifically for this projec

If not, select those columns to be viewed (Task Manager choose View->Select Columns... Then run your app and take a look at those columns for that app and see if one of those is growing really large. It might be that you've got UI components that you think are cleaned up but haven't been Disposed. Here's a link about this that might be helpful. Good Luck! share|improve this answer answ

Are you using the latest version of Elegant.UI? Is it fully error creating windows licensed? Maybe better to go to the tool providers support forum. 0 nick.crane 342 5 Years Ago If you are still having trouble with this then you need to find out where the error is coming from. If the debugger is not breaking in your code then you might benefit from trapping the first time exceptions. To do this use menu Debug/Exceptions... then check Common Language Runtime Exception to break when first thrown. Now when you debug your program it should break immediately the error occurs at the point in your code where it happens. You should now try to fix the problem by understanding what causes it, then prevent it from happening. For those occations when it is not possible to fix the problem then it is possible to trap the error using the try {} catch {} statement. Note that the first time exception trapping will still break even if you use try-catch. To test
