I've got some code which errors and I'm using the stacktrace to find out what the line number is but it seems to be giving me the wrong number
[Code]...
It seems to give me the line number of where the StackTrace is starting rather than the line number of what is causing the exception
Is there a way to show the line number of the line of code that caused an exception within a Try...Catch block?
View 5 RepliesI'm trying to show the line numbers with a stack trace when an exception is thown in my app.
This code is in the UnhandledException of ApplicationEvents:
e.Exception.StackTrace.ToString
It currently returns:btnOK_Click(Object sender, EventArgs e) at with no line number at the end.
I have set the project to create debugging info in Project Properties > Compile > Advanced compile options > Generate Debug Info = pdb-Only, and deployed the PDB file with the app, but still I don't get any line numbers.
I'm using VS2008 Standard, vb.net.
I have an application and I want to use the "Line Numbers" to error catch.
So how do you call the line number of the exception?
It is SO useful for me to know the line number where an exception occurred. I inherited a project someone else created and I suspect he has some inherited Project properties from his initial Visual Studio Express solution. Where do I go to restore that critically important feature?[code]...

For debugging purposes, I would like to create a log file showing each function that gets entered. I understand everytime a function is entered, it is added to the stack trace. Is it possible to get events from the stacktrace everytime a new function gets added so that I can log it? I don't want to write log messages to every one of my functions in code, I would like to automate it. OR, is there another way? (I am using VB 2008 Pro)

but when I use that, it acts funny. I have it in my textbox's.keydown event. So if I were to use the arrow keys to navigate around text then it gets thrown off very easily. How would I do this?
Is there a way in .NET (VB.NET or C#), when an exception happens, to dump the stacktrace of each thread? Basically I would like to reproduce what happens in Visual Studio's Debug->Threads window to see what each thread was doing when the exception happened
View 2 RepliesI just did some analysis by using a global function which is called GetCallingMethod in my case.
Mostly it works great. But some cases the application is blocked. It is blocked when closing the application. When going to "pause" in Visual Studio, it stays on the new StackTrace line forever.
In my application I am using third party references, multithreading and several classes. But all that should not be a problem and should not lock the tracer class as far as I imagine. I am using Visual Studio 2010 Ultimate in this case.
This line will never be left in development area. Application will is frozen. Try/Catch will not force the procedure.

I've recently converted some VB 6 code over that used the old non-structured exception handling. I also have some .NET classes that raise custom exception classes. When the code was VB6 I used to expose my .NET classes using COM interop and errors raised from .NET classes were being caught correctly in VB6. Now that everything is .NET the old non-structured exception handling is still there in the converted classes. But now the Err.Number is not reflecting the HResult of the error raised. I wrote a simple little Windows Application form with 2 buttons to simulate the problem. Here is the code snippet:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo ErrHandler
Err.Description = "Test Error"
[code]....
If you click Button1 you get the following message:
-2147215379 : Test Error
If you click Button2 you get the following message:
5 : Test Exception
i got an error when i simulate the thing. To write in a file any "billet" generate the error is : Invalid CastException was unhandled: The conversion of the chain "[" in 'Double' was invalidAlso, i don't know how to make a series of random number between 1 to 49 for each number of a Billet object
Here's my code
Public Class Billet
Dim _num1, _num2, _num3, _num4, _num5, _num6 As Integer

i want to know what are the methods in order for me to extract the information that is stored in the exception. i also would like to know how do i extract the code line that caused the exception to occur.

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:

I wanna put the snippet to a class, everytime I call logMsg method to log my message with line number in source code.But I found if I put the snippet above into a class, the line number was always same, that's the line which I new 'st'.The function is exact same with _LINE macro in C++.
