JIT Debugging failed with the following error: 0x800405a6

[harish]

Hello all,

I am trying to use C# assembly /dll (which has public methods and events),
... trying to use it through a VB6 client..

I get the error,
JIT Debugging failed with the following error: 0x800405a6
what seems to me is like the error occurs when an event is fired from .net
code... since i observe the error only when its possible for an event to
occur.

When I test the c# assembly with a .net client the error doesn't occur.. i
believe its because of the com interop related code. Below is my code..

Thanks for your time and help

I solved this..

There was no problem with the .net code below..
I had used different objects or actually different interface entry points
for accessing the methods of the object and the events, through a vb
client.. this i did to allow intellisense when coding through vb (or to use
early binding through vb).

Now in my client code i use the object's instance for accessing both the
methods and events rather than any interfaces i made available through code
below.

This solved the problem.
In effect i lose early binding and intellisense in the vb client.. but code
works great.

Thanks,
