Question

This may be a debugger issue, but here goes:

I have this piece of code:

Private Function Connect() As Boolean
    Try
        sessionBegun = False
        connectionOpen = False

        rp = New RequestProcessor2()

        rp.OpenConnection2("","EZSystem", QBXMLRPConnectionType.localQBD) 

        connectionOpen = True 
        ticket = rp.BeginSession("", QBFileMode.qbFileOpenDoNotCare)
        sessionBegun = True 

        Return True
    Catch e As COMException
        exceptionHandler.HandleConnectionException(e)
        **Throw New QuickBooksConnectionException(e.Message)**
    End Try
End Function

My intention is to ‘convert’ the low level exception into something more meaningful, so I throw an exception of my own creation. I want this to bubble up to a place where I can handle it.

However what is happening is my debugger breaks and tells me that an exception of type “QuickBooksConnectionException” was thrown.

I know that, I just threw it, why are you catching it?

From what I’ve read, this ought to work, and there doesn’t appear to be an analogous Java throws keyword, so perhaps it is my debugger.

I am using SharpDevelop.

Thanks,

As written, your code throws an unhandled exception, which is always going to cause the debugger to balk. You just have to catch the QuickBooksConnectionException in the code that invokes this method. (And you’re right, there’s no equivalent in C# to the throws Java keyword.)
