Dear All,

I am using an un-managed code in my VB.Net application and some times
a native exception occured which is not captured by the Try/Catch
block.
How I may capture the native exception?

Regards,
Muhammad Arif

Exceptions cannot be marshalled across the native/managed boundary.

Dear Chris,
Thanx for the reply .... but what is the solution of this problem. Any
alternated which may capture the native exception and prevent my
application to be crashed.

Muhammad Arif

The "solution" is to make sure your native code handles all error
conditions. You shouldn't be throwing exceptions to external callers.

Dear Chris,
The native code is provided by my vendor in the form of a dll and I
can't handle the exception in native code. Is it possible to do some
thing with my code to capture this exception.

Muhammad Arif

Not that I'm aware of. The best you can do is to try to not pass data or
call methods during a time that might cause an exception. I'm very
surprised their DLL throws exceptions - I'd call that a bad design. You
might talk with the vendor and see what they suggest.

Maybe you could write your own DLL which sets up exception handling for
unmanaged code and calls the real DLL on behalf of your managed code?
