.net hang on Application.DoEvents

One of our legacy products is the Winforms application, and instead of using background threads, it does everything on the main user interface thread. It has a constant loop running in this main thread that calls Application.DoEvents () every 20 ms. From time to time, the application simply freezes when calling DoEvents. My question is, how do I know when the call queue causes code to hang?

PS Does anyone know a tool that I can use to get a stack trace for each thread in a process?

In addition, this only happens on the production client, and we need to get a fix. Unable to install VS on client.

I found the tool I was looking for. Windbg

It can get a stack trace for the current Windows process. However, this application requires PDB files.

You can do this in the visual studio, just join the process, cancel execution and open the thread windows.

Menu: Debug-> Windows-> Themes
