Throw An Existing Exception While Preserving Its Stack Trace In VB?

Nov 18, 2011

If I have an existing exception object (I'm not in a catch block, I just happen to have been given an exception object), is there any way (re)throw it while preserving it's stack trace?

The context for asking is that I'm writing a RunWorkerCompleted handler. If an error happened while running the background task, then this will have shown up in the Error property of the RunWorkerCompletedEventArgs. To keep the code simple I want to use the same error handling code to trap this, or any error that happens later during the handler. That means I need code like this:

Private Sub OnDone(ByVal sender As Object, ByVal e As RunWorkerCompletedEventArgs)

[Code]...

I don't think that using an InnerException here (ie. saying something like Throw new Exception(ex)) will work because then I have the problem that my Catch block has no way of knowing whether the exception it's supposed to be handling is the outer one or an inner one. StackOverflow seems to have various similar questions, but I've not found anything that describes this particular situation.

Find Exception Stack Trace Outside Of Visual Studio?

Mar 11, 2010

I have my .net app running on my home machine, and at one point it threw an exception.Problem is, Windows doesn't tell me what the exception is, just says that it stopped responding and closed it.I want to find the exception and stack trace so I can debug it, since I can't to reproduce the problem inside visual studio.The machine is running Windows 7 x64. I found in the event viewer some minor information:

Problem signature:
P1: server info.exe
P2: 1.4.0.0

[code].....

So based on that I can see there was a null reference. I remember way back when I was on XP, when the application crashed it would show the whole exception stack. Can I find that information somewhere?

Can't Get Stack Trace From OjbectDisposedException

Jan 7, 2009

We have this funky little ObjectDisposedException happening now and again. But only on production machines, of course ... can't recreate the issue on my dev unit. So I trotted on out to the Microsoft site to see what members of this exception I could use to figure out what's going on. Microsoft says that one of the members is StackTrace. I double and triple checked that I'm looking at .Net 1.1 information as I'm pretty sure that's what I'm using (how can I check that?). Here's the page I found - [URL]

So I go back to my program to write something useful to the event log so I can figure out what's going on. And when I look at the members of the ObjectDisposedException available to me I only see the following: GetBaseException, GetType, InnerException, Message, ObjectName, ToString.

what happened to my StackTrace member? I sure could use it if I could figure out how to get to it.

How To Get A Stack Trace In .NET In Normal Execution?

Jul 15, 2010

In VB .NET, I know I can get a stack trace by looking at the value of ex.StackTrace when handling an exception. How can I get the functions on the stack when I am not handling an exception? I am looking to implement a logging system of some sort to record the steps the user takes prior to a crash to assist in debugging.

Getting Stack Trace Information From A Dynamically Loaded?

Oct 26, 2009

My goal here is to get stack trace information from a dynamically loaded assembly. If the dynamically loaded assembly just throws the error back to the caller, the stack trace information doesn't tell you the location in the dynamic assembly where the error occurred. If I throw my own exception, passing in the original exception, it will get added as an inner exception and will have the information need. I'm trying to avoid changing all my dynamic assemblies to throw new exceptions.

Public Class ErrorPlugin
' Example Function from plug in DLL
Public Function SimpleExample() As Double
Dim RentedUnits As Double = 42

Catch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception

May 8, 2009

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

VS 2010 More Extensive Error Logging "stack Trace"?

Dec 16, 2011

I created a class that I use for error logging. I have one method that accepts a parameter as an exception. With that exception, I created the error log and I write the message as well as the stack trace. With this, I'm finding that I'm not always getting detailed information. Usually, the stack trace shows me line number in which the error occurs, which allows me to pinpoint the issue.

Catch / Handle And Then Again Throw Exception?

Jun 26, 2009

I ran into an interesting dilemna today. I have a function that handles information and checks for duplicate values, then returns the next number that is not a duplicate. So, I have something like this:

Public Function GetNextNonDuplicateNumber(NumberToCheck as Long) as Long
//the non-duplicate the function will return
Dim NonDuplicate as Long
'duplicate
If CheckForDuplicate(NumberToCheck) = True Then
Throw New DuplicateException()
[Code] .....

As you can see, I want to handle the exception specifically, but I also want to throw it when I'm done because I want to alert other code outside the function. The problem is that simply throwing it exits out of the function with a null value.

VS 2005 - Throw An Exception When Print To The Printer Using The PrintDocument

Oct 29, 2009

When I print to the printer, using the PrintDocument, I want it to be able to throw an exception if there is a problem. Currently, if I print to a printer that has a jam, is offline, or doesn't even exist, VB still thinks it printed fine. I never get an error. How can I have the printer report back to my program so that if I print to a printer that doesn't even exist, it wont let me do it? I just tried adding a LPT1 printer to my computer (and there is no local printer). I called it some random printer and installed some random driver. Then used my program to print to that printer and never got an error.

Make The Exception Propagate Up The Call Stack?

Mar 4, 2011

I have created a UserControl and I'm using a simple app to test it. However, when my code in the control throws an error, such as:

If ColumnIndex < 0 Then
Throw New System.IndexOutOfRangeException("ColumnIndex cannot be less than zero.")
Else

the debugger opens the module of the UserControl in the IDE of the testing application and highlights the code above, instead of highlighting the call made by the testing application itself, e.g. LG.Add(-1, ...).How do I make the exception propagate up the call stack?

Preserving Variables Through Postback?

I'm creating a Website and I noticed that when the page reloads due to a postback, My variables all are unloaded so I have a Null variable,

For Example I'd Declare a String With an initial value of "" then later in the code set it to "Some Value", when a button is clicked to cause a postback, this value then becomes "" again

Is there some way to preserve variable so their values remain the same after a postback

Asp.net - Preserving Dynamic UserControl On PostBack?

Feb 5, 2012

I'm dynamically loading User Controls into a div, which I need to preserve on postback in order to call a Save method once the user is done editing them. The div and all the User Controls have the EnableViewState = True.

ASPX Div Declaration

<div id="dynamicDiv" runat="server" enableviewstate="true">
</div>[code]......

So... the controls load fine, but I can't find a way to preserver them on postback, I can't reload them because the user has already input data into the usercontrol (which is what I need to save).

P.S. I tried adding them to a list and then adding the list to the ViewState, but I haven't been able to properly serialize the control. I implemented ISerializable for the userControl's code behind but then it says the ASCX is mot marked as serializable with

Type 'ASP.controls_userControlType_ascx' in Assembly 'App_Web_pn5vxhpw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
