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.

I'd say the form's resource file has become corrupted. You could try right-clicking the form in the Solution Explorer and selecting Exclude From Project, then right-clicking the project and selecting Add Existing Item to re-add the form to the project and (hopefully) regenerate the resource file. If this doesn't work, you could do the same thing again but this time delete the RESX file for the form before re-adding it. You might want to make a backup copy of the solution folder before trying this, just in case. 2007-2016 Why is my data not saved to my database? | MSDN Data Walkthroughs MSDN "How Do I?"

The limit seems to error creating window be 1000 windows but as you can imagine it's really hard to think that someone could write a program that uses 1000 opened windows. The problem is that somewhere in your code you think you have closed forms and released controls but they're just hidden and continue to occupy memory and handlers. I had this problem with a software developed by my company, RYHAB Solutions, and we lost a lot of time to figure out where the problem was. At the end we understood what was going on. We had in our code something like this: public sub CloseWindow() if typeof(me) is mybaseclass then me.visible=false else me.close() end if end sub We used this sub in a base class so all the classes that hinerited by this returned "mybaseclass" when calling typeof(me).
