SEHException outside VS and no problem in debug mode running from Visual Studio

P/Invoke Problem

Security

I have .Net project where I’m calling C++ DLL. It is working fine than I run it in Visual Studio Environment (debug mode). If I run the same code outside Visual Studio I’m getting External component has thrown an exception. System.Runtime.InteropServices.SEHException. The same problem exist if I run this process outside VS and attach VS de**** to this external process.

Any ideas

I think this may relate to a security, I added

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]

To my method but it did not help

It's not .NET security, you're getting an unmanaged exception. There are just a million different ways in which a C++ DLL can throw SEH exceptions. The typical reasons are heap corruption problems and bad pointers. You'll need a good unmanaged de**** to trap this exception and a working understanding of assembly code. Look at the Debugging Tools for Windows.

Well, the real question is why it is working fine in IDE but not outside of IDE I do not get any exception while running in VS.< xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Interesting thing. the real question was not answered. Than I posted it again without security issue and ask why it would work in IDE and not outside, my post was simply deleted!!!!

Nice work at Microsoft!!!
