View 1 RepliesExceptions Must Be Exclusive - Exceptions Will Ever Occur Simultaneously ?
Dec 26, 2009I've just skipped around a few inbuilt VB classes' methods which throws exception. of all that i've came across, methods may throw multiple exceptions but ALL of them are exclusive, meaning there is no way 2 exceptions will ever occur simultaneously, yea and i was trying to make my class throw 2 exceptions simultaneously, hence this question, must all exceptions be exclusive?

.net - Old Classic ASP Pages Getting Caught In MVC Route?
Dec 17, 2011I am converting an existing classic ASP website to (VB) MVC and I don't want any of the existing URLs to break. I have read many posts (like this one: Routing Classic ASP Requests To .NET - SEO Redirects) about how to do the proper 301 redirect. With the latest MVC release, I've gathered that
Response.RedirectPermanent(objRedirect.new_url, True)is all that is needed.
I have entered all of my old URLs in a database table with a corresponding column of the new URL. I have added code in my custom 404 page to get the original URL:
Dim strURL As String = Request.RawUrl.Substring(Request.RawUrl.IndexOf("aspxerrorpath=") + 15).ToLower()
so I can look it up in the database. (Interesting sidenote, MSDN's documentation here - Redirect Mode - seems to say that if I set RedirectMode=ResponseRewrite in the CustomErrors section of my web.config, I won't have to worry about doing the above, but when I've tried that, I get IIS errors saying it won't serve an ASP page?The problem I am encountering is that any of my old, Classic ASP URLs that have the same directory as a new MVC route are somehow being partially routed. For example, "/test/default.asp" shows up as "/test/test" in the above strURL variable of my error page.

C# - Design Time Exception Not Caught In WinForms
Oct 4, 2010I have a form that is used at design-time to configure various properties. I've tried two ways to do a form-level catch all exception:
(1) I add a handler to Application.ThreadException in the constructor.
(2) I wrap the Show method, of the form, in a Try/Catch block
Both of these work at run-time when I test by adding a property grid to a form and set my component as the SelectedObject. However, at design-time the form simply closes with no message whatsoever; neither my message nor any message explaining that there is an unhandled exception. This is not about debugging at design-time. It's about how to present the user with a friendly message when my type editor encounters an unhandled exception.

VS 2008 - Send Email But Stuck With The GeneralFailure Error Caught With Try And Catch
Jun 3, 2010I am currently trying to send Email but am stuck with the GeneralFailure error caught with try and catch. I got the sample code somewhere off the internet last week and modified it when I have the chance.
The following is the code I am working on for now.
Private Sub btnSend_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSend.Click
Dim message As System.Net.Mail.MailMessage
Dim mailClient As New System.Net.Mail.SmtpClient("smtp.live.com", 25)
[CODE]...
Is there anything unnecessary, missing or am I on the wrong track? Right now I am trying to test send a mail from hotmail to gmail or another live account. Also, I have tried searching through the internet for a solution and some said I need to have IIS which I had it installed for it to work. Another said I need to add a reference but did not specify it. Those were pretty old messages though.
Thrown Custom Exception Is Immediately Caught In The Same Catch Block It Is Thrown From?
May 13, 2012This may be a debugger issue, but here goes:I have this piece of code:
Private Function Connect() As Boolean
Try
sessionBegun = False[code].....
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.

Log Exceptions In VB, On An ASP.NET Application?
Apr 6, 2009I'm working on an ASP.NET web application, written using Visual Basic, and I'm trying to track down an error message that I'm getting.I'd like to get it to log the exception to a file (or the event log) so I can see it, as the error only occurs on the production server, and not on the development environment (therefore VS isn't installed on there...).
Does anyone have any thoughts as to best practice as to how to do this ?
Swallowing All Exceptions
Dec 25, 2010Why is the net filled with examples like this? Why do people just chuck try catch around any expression with out the slightest thought about pre-validation?
i would never just add try catch and not handle the exception. I tell people this is basically on error resume next in disguise.
Is an exception ever unimportant to just use try catch but with out any message?I really want to progress as a programmer but have i been approaching all this wrong?

View 3 RepliesCatching Exceptions In Soapclient?
Feb 24, 2012Take the TripPriceService.wsdl from this link Add a service reference(ServiceReference1) to a windows application, by giving the wsdl from the mentioned wsdl file saved in local folder. My question has two parts
1) Is the below fault message a valid soap fault as per the wsdl(TripPriceServiceException)?
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:trip="http://trip.price.service">
<soapenv:Header/>
<soapenv:Body>
[code]....
2)Now How to handle and catch the detail tag, when the response is a soap:fault?
Imports windowsapp1.ServiceReference1
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim obj As New ServiceReference1.TripPriceServiceFacadeClient
[code]....
The line obj.getTripPrice, invokes the service. However will it throw an exception if the response is a soap fault(of type TripPriceServiceException)? How to handle such cases, do we need to use ServiceReference1.TripPriceServiceException? We are in a need to handle such faults in our webservice client.
