  4. In the meantime, you can useMemory Profiler to check for a possible memory leak.I hope to hear from you soon.
  5. There's not doubt that you can find other approaches.The first thing you should do in my opinion is building your applications around use cases and scenarios.
  6. As I already noticed,this exception in most cases occurs because the application creates too many handles.

Here is how we're doing this in my client's application: We use TabControls and we create the content of each tab on the fly, when it becomes visible; We use expandable/collapsible Which does something unfortunate, it again changes the HideSelection property. In our case, we were getting the dreaded "Error creating window handle" exception before the total number of User Objects in the current session reached 11,000. This repeats over and over again when your GotFocus event handler yet again runs for the new native control.

Also include PC name, currently open forms count (and their names), process start time (and time running), disk/CPU/RAM usage and all the counter values mentioned above. Perhaps it is creating too many window handles?
