Some notes on finding the cause of a .NET app generating a “application has generated an exception that could not be handled”
Posted by jpluimers on 2012/11/15
A while ago, one of the users at a client got an error in a .NET 1.1 app of which the sources were not readily available:
“application has generated an exception that could not be handled”
I think it is a e0434f4d exception.
This particular site has very strict rules about what you can and cannot do as a developer. Which means that on a production system, you basically cannot do anything.
A few links that should help me finding the solution, and escalate far enough upstream to get someone with local admin rights to assist me:
- Common Language Runtime Debugging Services Application has generated an exception that could not be handled.
(requires a local admin to install .NET 1.1 SDK) - Kofax Forums • View topic – VRS 4.1 Installation Problems.
(requires a local admin to install Process Monitor) - Download: Debug Diagnostic Tool v1.2 – Microsoft Download Center – Download Details.
(requires a local admin to install) - dllimport – KERNELBASE.dll error running c# app on Windows Server 2008 R2? – Stack Overflow.
(requires a local admin to run WinDbg, and a way to get through the company proxy with that in order to load the symbols from the microsoft server)
If WinDbg is allows to be ran, these should help me:
- c# – How to solve this error that is shown on Windbg? – Stack Overflow.
- Troubleshooting an InvalidProgramException.
- c# – Using WinDbg to Inspect Method Parameters In Raw Memory from Crash Dump – Stack Overflow.
- Windows Debuggers: Part 1: A WinDbg Tutorial – CodeProject.
- Getting started with windbg – part I – Speaking of which… – Site Home – MSDN Blogs.
