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.
[Code]...
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.
View 3 RepliesWe 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.
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.
View 3 RepliesMy 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.
Most examples I have found use Trace.WriteLineIf e.g.Trace.WriteLineIf(mySwitch.TraceError,"my error");'but using Trace.TraceError("my error"); appears to give the same result (when sent to a TextWriterTraceListener)

Additional note: My function does need to work for UNC paths also (local and/or network).
could you tell me, why I get the stack overflow error on this code?
Dim ev As Double = datum.Year * 365 * 24 * 60 * 60
Dim honap As Double = datum.Month * 30 * 24 * 60 * 60
Dim nap As Double = datum.Day * 24 * 60 * 60
Dim masodpercek As Double = ev + honap + nap
The double datatype should be enough.
This code worked fine in WinForms under .NET 3.5, but since I've started using WPF and .NET 4.0, it no longer works (although I'm not sure if this is a coincidence or not).

View 7 RepliesI'm converting some C# code to VB, but the VB code gives me an 'unbalanced the stack' error.A call to PInvoke function 'Application.WinPcap:: pcap_ findalldevs' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.This works fine. [code] Here I get the 'unbalanced the stack' error on the line: "If pcap_findalldevs(tmpptr, err) = -1 Then".The only difference I see is "ref tmpptr" in the C# code, but I'm not sure how to translate that to VB.

I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.

Possible Duplicate:How can I handle a Validation.Error in my ViewModel instead of my View's code behind?The usual examples of how to use Data-Validation in WPF usually only involves defining an error template for the control and displaying the error message in the control tooltip.

I've declared it as follows:

Now I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..
I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?
