Err.Raise in EnterpriseServices Component

Here is the situation.

I have custom err.raise statement Err.Raise(vbObjectError+9000, src, desc) in an ES component. And when the client tries to trap the error, the error number that is returned is always 5, but I can get src and desc values. Is there any known problem with errors raised from ES component

Thanks.

    The workaround is throw COM exception like this:

    throw New COMException(Err.Exception, vbObjectError + 9500)

    there is a marshaling problem if you use Err.Raise(vbObjectError + 9500) in ES component.

    Note: You can use Throw inside On Error Goto block, and it works.

    actually we are in the process of migrating vb6 components into .NET, and concentrating more on the VB6 biz components to be migrated properly; so we are kinda struck with the vb way of error handling for the time being... however if there is no solution for error 5 problem, then we would rather go with exceptions!

    thanks.

    I would throw an exception instead of using err.raise

    I'd saied that not would but u MUST throw exceptions.
    .NET is type-based system, we should forgot about code errors at all.
    I recomend author to read this article about Exception Management http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnbda/html/exceptdotnet.asp
