I have a silverlight application elevated trust deployed at my company and some errors I get the "debugging resource strings are unavailable" I was wondering if there was any way currently for silverlight 4 to get the full error message without installing the developer version of silverlight on every single machine.
View 2 Replieswhere can I find the full list of VB.Net Exceptions? I saw one similar question in this forum, but couldn't find the answer.
View 1 RepliesI'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?
View 1 RepliesI have a LOB app written in VB.NET with a WinForms front-end and SQL back-end. After many months weighing up how to get onto the Web, I decided last month to use Silverlight 2. Now, Silverlight 3 Beta is out, but there is no end-user runtime.
Does anyone know when the runtime will be available for deployment of SL 3 apps onto client sites?
My dev timeline is about 3 months: should I persist with SL 2 and then u/g to SL3, or jump straight in to SL3?
I have made quite a nice and tidy little game. Its based around space invaders and works quite well. however because i have finished my college project almost 2 weeks ahead of the assignments release date, my tutor has asked me to tweak my project and make it better.So far i have added a full main menu to the game and a full splash screen. I would like to add in a section for recorded high scores but have no idea how to attempt this at all.
View 3 RepliesI need to write a program that indicates the larger of two variables using exceptions.I'm not sure if this is an acceptable code. I'm new at this and attempted with this code here:
[Code]...
I normally wouldn't use an exception but I am asked to use one, I'm just not sure what kind of exception would work best.
I'd like some advice on building in known errors. Let's say I have a Windows form that needs to set the source path of an image in an object. It must be:
A valid path
An image
A PNG
[code].....
I have a class that has a method A and a helper method B, method A internally calls method B. method B throws few exceptions to the caller also method A throws it's own exceptions, Assume method A throws "NotImplementedException" and Method B throws "SQLException", in the XML of each method, one which method that should put "NotImplementedException" and "SQLException" in <exception cref></Exception >
Should i put both exceptions on the XML of method A?
I'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 ?
Why 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?
But what if you can not think of the exception that could be thrown?for example
Private Sub ListCurrentlyRunningProcesses()
Dim ActiveProcesses() As Process = Process.GetProcesses()
Try
[code].....
When you use Try Catch for Exceptions, will
Catch ex As Exception
Catch any possible error that could occur or do you have to catch each exception separately?
Is there a way to catch these Exceptions? (I am not looking for "just put try/catch or on error goto around them"). I am trying to find out if these errors can be caught by something outside of them.[code]...
View 1 RepliesI am trying to implement multibinding in Silverlight using VB.Net. I have found a very good reference for an implementation in C# here. I spent some time trying to use various converters to migrate it into VB.Net but I still didn't get it working properly. So..
I'm looking for some references that exemplify how MultiBinding can be done in VB.Net. Also an example using Silverlight 5 beta would be fine (I read in a post right here on Stack Overflow that it supports multibinding).

View 3 RepliesTake 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.
I would like to turn of this exception in the debug menu but I am not sure how or which one to uncheck or check.."ObjectDisposedException was unhandled"
View 6 RepliesI'm creating a class library that contains a series of functions with Try...Catch blocks to handle errors. When i run another application that uses the class library, and call a function in the library using parameters that i know should cause an error (i.e. divide by zero), i don't get an exception thrown.
Can you not use Try.. Catch blocks in external libraries? If not, how are you suppose to handle errors in these functions?
I have a application in which dll of another project added,
In my dll's I have several exceptions defined, and when specific errors occur
I throw these exceptions with the assumption that the main application will catch and handle them if the DLL does not.
but when any specific error occurs in dll main application cant able to catch it and whole aplication get closed. i have added an snapshot which appears when any error appears in dll
how do i handle the exception raise in dll from main project
Is there a way to configure the debugger or write code in such a way as to get more information when first chance exceptions happen? I understand they are generally not harmful and I do quite a bit of exception handling in code but when I'm doing database operations it's to know when first chance exceptions occur. Of course I can see them in the Immediate Window in VS but I would like a full stack trace, not ust a line saying "A first chance exception..."
