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.

My problem is that i need log the stack call. I know that i can put a breakpoint in code and choose the debug menu option "call stack", But that is not a solution for me, because i need all the methods called by the application, not only the last until the breakpoint.

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.

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.

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?

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.

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.

This probably has an easy answer, but I haven't been able to find one yet. I was wondering if there was a simple solution to exporting the page-level trace results of trace.axd to a log file of some sort.

I have a .NET DLL that writes to the Trace. But it seems that when I call my DLL from a VB6 EXE the trace is not working. I have created an myApp.config file in the EXE folder with the trace configuration, but this does not solve the issue. I've also tried creating the Trace objects in code, but doesn't work:

I was just wondering why there isn't a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are being executed in an application. This feature is a part of log4J. I know I can create a custom level like is talked about here but I don't want to put time and effort in something I feel should be part of the library itself. Do you know about a log4net extension library which implements this or why this wasn't a part of the port to .net ?

I have a property ProjNum that when equal to 10 should have city = 'Richland'. I have placed some if statements in the code with breakpoints for ProjNum = 10. When using [F10] to go through code city stays Richland but when object is shown in a grid at the end of the process the value is not Richland. Is there away to find out when the city value changes?

I have a winform that is taking too long to load. The form has a gazillion of controls and I would like to see how much time each control takes to load.If it were a web app, I would have just turned the trace on, but I can not find anything similar in winforms.

Working through trace tables and wanted to check to see if my results where correct, I have designed the following code to check each stage of the loop, but the code keeps throwing up an error about casting when i try to run it. I can see when the error comes back that the writeline is holding info but what have i done wrong.

I have been making a order processing system for a friends company and have 99% completed it. i was going through everything double checking all the components and i put a "DotNetBar" component on the form but then deleted it as i didnt need it. i only have a trial version of the dotnetbar and do not plan on publishing the software with the component on.
so after i deleted the component from the form i built a test version of the system and installed it on a different computer but when installing an error appeared saying something along the lines of dotnetbar component cannot be found. i couldn't find any trace of the component in the page.designer.vb file.
im by far no expert in vb (this is the first real program i have developed for actual use), i cannot find any way of getting all traces of the component of the project.

im looking to do a trace route to an ip (specified in a text box) and have the results displayed in a textbox. I know that this has been brought up in the forums before but im yet to find a version thats compatible with vb 2008 express edition. The vb.netmvps example is exactly the functionality im looking for but it throws up 80 +errors(*** is no longer supported etc)[URL]the host resolution isnt an issue becasue i already have the list of ip's and corresponding host names that i would be tracing in a db.
does anyone have a tracert app that is compatible with this version of vb or indeed know where i could find one ?

How can you trace the amount of memory used by each variable, process in a program? I tried CLR 2.0 but am not sure how to read the results. Are there any really good articles on CLR 2.0 that describes what I am looking for?

In my case, I'd like to output to a ListView or TextBox or for that matter, any control which can accept text. For this purpose, I'd like to have a general purpose Trace/Debug listener which I can hook to in order to process the messages (convert to a ListViewItem or something) before outputting it. Is there any way I can achieve this or do I have to build my own Trace Listener? If it's worth noting, I run VS2010 ultimate & VS2008 professional. Solution should be in preferably be in VB.NET but C# is okay.

This may be more of an OOP concept question, but here's what I'd like to do.I have an application that outputs debug information using System.Diagnostics.Trace.WriteLine so it can be viewed with DebugView.I'd like to override/extend (not sure of the proper terminology) this method to log the text to a file instead, or maybe in addition to the Trace output. This would allow me to write a new WriteLine method for my app, and I could leave all my other System.Diagnostics.Trace.WriteLine statements unchanged throughout the rest of the application.?
