Hi all I'm having the following issue in my VS 2003, .net framework 1.1, vb.net wsmq application and haven't been able to find a similar one addressed on the forum:
When I try to instantiate a queue manager and it fails, the exception is caught in the following block -
1. Catch ex As Exception
2. Dim mqexception As MQException
3. mqexception = CType(ex, MQException)
4. strResponse = ex.Message & " " & IIf(ex.InnerException Is Nothing, "", ex.InnerException.Message) & " " & mqexception.ReasonCode
5. End Try
Ideally, I would execute all the above lines and get a nice strResponse string. However, when I step through, lines 1 and 2 execute, and then I jumnp out of debugger and focus goes to the web page, which has been rerouted to an http 500 error page.
Does anyone know why lines 3-5 are skipped?
Thanks. |

So I've discovered that the cast to mqexception is an invalid one, so that's throwing an exception.
So how do I access the mqexception.reasoncode? I can't catch these exceptions as mqexception for some reason. That's why after catching it as an exception, I'm casting it to an mqexception...
Any advice? |

Got it! It appears I needed to do the cast as follows:
CType(ex, IBM.WMQ.MQException)
I'm not entirely sure why, though, since "Dim mqexception As MQException" had no problem, and thus MQException was in scope.
Oh well, hope this helps somebody else! |
