Which language are you using ?. Have you checked the documentation (see the
"try" statement) ?

Else please be a bit more explicit on what you are looking for...

Hello Ashutosh

Yes, .NET has the capability and support for SEH. In fact, the CLR
implements its exception handling on top on Window's native
Structured-Exception-Handling (SEH) model.

Take VB.NET as an example,

Structured Exception Handling Overview for Visual Basic
http://msdn.microsoft.com/en-us/library/8a9...
<quote>
Visual Basic supports structured exception handling, which you can use to
create and maintain programs with robust, comprehensive error handlers.
Structured exception handling is code designed to detect and respond to
errors during execution by combining a control structure (similar to Select
Case or While) with exceptions, protected blocks of code, and filters.
Using the Try...Catch...Finally statement, you can protect blocks of code
that have the potential to raise errors. You can nest exception handlers,
and the variables declared in each block will have local scope.

Hi,
Thanks for the reply. I think I didn't make my question very clear.

I know how the C++/C# try-catch-finally are implemented internally. The
catch block is implemented as the exception filter of the SEH.

My question here is, is there any support to directly use the SEH and
not the C++/C# try-catch-finally in C#? The documentation of .Net
doesn't have any keyword as __excpet

Thanks & Regards,
Ashutosh

Hello Ashutosh,

May I ask why you would need to directly use the SEH and not through the
C++/C# implementation? Given a specific scenario, I may be able to help to
find out some solutions. At the moment, I do not know a way to use SHE
directly, but I will do my best to perform researches and help you with the
issue.

Thanks,

Hi,
Thanks for the reply!!

I am not having any issues. It's just that if I could use it my life
(and the code) will be much more simple...if I use the
EXCEPTION_CONTINUE_EXECUTION feature...

Thanks & Regards,
Ashutosh
