.net - Building A True Error Handler?
Jun 4, 2010
I am trying to build an error handler for my desktop application. The code Is in the class ZipCM.ErrorManager listed below.What I am finding is that the outputted file is not giving me the correct info for the StackTrace.Here is how I am trying to use it:
Try
'... Some stuff here!
Catch ex As Exception
Dim objErr As New ZipCM.ErrorManager
[code]....
What is happenning is the .GetFileLineNumber() is getting the line number from 'objErr.Stack = New System.Diagnostics.StackTrace(True)' inside my Try..Catch block. In fact, it's the exact line number that is on. how I can catch the real line number the error is occuring on?

While I'm trying to build a solution after I've changed a little in its code it gave me an error and even when I've removed the code the same error appears.
"Unable to find manifest signing certificate in the certificate store." (That is the Error and it either stop building or run last successful build.)

I am getting an "ArgumentOutOfRangeException" on parameter index whenever I try to instantiate a session factory in nHibernate. The error comes from a procedure deep in the bowels of nHibernate. This is on a fresh project with a pretty simple three tier architecture. The data layer maps the nHibernate classes to simple interfaces which are implemented by the business layer.Currently there is only one interface set and mapping file being used by nHibernate. Hopefully my issue is easy to spot.
Here is the function where I build the sessionFactory.
Private Shared Function SessionFactory() As ISessionFactory
If _sessionFactory Is Nothing Then
Dim config As New NHibernate.Cfg.Configuration
config.Configure()
[code]....
Edit2: When I remove the discriminator I no longer get this error. Am I not doing that right?
Edit 3: When I download the source code for nHibernate, build it on my own, link to it's debug output and run it, I get a completely different error about ProxyFactoryFactory not being configured.

There is definitely a Building entity in the pbu_housingEntities?

I am planning to use a shared variable to implement a logging facility. Have a look at the code below:
Imports System.IO
Public Class TestClass
Public Shared objError As New StreamWriter("C:Test.txt")
End Class
[Code]....
I think I have found my answer here: [URL] "A static variable continues to exist and retains its most recent value. The next time your code calls the procedure, the variable is not reinitialized, and it still holds the latest value that you assigned to it. A static variable continues to exist for the lifetime of the class or module that it is defined in."
I am not convinced that this is the best way to create a logging facility.

i have a method SaveRecord() in teh data access layer (DAL) that should return the status of the query execution to the Business Layer (BL)
There are three possible messages the DAL could return to BL: 1. Successfull Execution --> error NO: 12. Error: record already exist --> Error no:23. Error: SQL Errors while executing con.Open() or cmd.ExecuteNonQuery() --> Error No: 3
I'm planning to return error no to the business layer so that appropriate error message can be assignedd.
Is there any issue that my current technique might face becasue i'm not creating a seperate ErrorHandler class to assign those error numbers and error messages?
Should i create a seperate error handler class? If i need to create a error handler class should i create it in the DAL or BL?

I've tried several variations of this. If the Cancel button is clicked on the dialog, an exception occurs, and a crash in an executable. I thought the "Exit" statement would take care of it. Not true. What I need is an error handler. In VB6, I used "On Error". I would prefer to not do that here.

i made a .exe launcher, i was able to launch a program named minecraft using the process.start. But this certain program generates error usually, so what i tried to do was get the window title of the minecraft and categorize if its an error or the actual game.
This is what i did:
Code:
So this transfers the window title of the launched program to a textbox then the "if statement" compares it and if its the error, it kills the error and relaunch the program. This is already a working program but i want to make the launching faster, the problem is if i hasten the interval of timer 2, it sometimes kill the non, error program that successfully launched. If anyone can help me, Hide the error or remove it please do help me. Im not yet an expert on vb.net but i want to learn from the best.

My job is requiring some visual basic programming and i've only programmed in C#.So i have this code:
Public Custom Event Command As JQDialogEventHandler
AddHandler(ByVal value As JQDialogEventHandler)
commandHandler += value[code].....
I'm getting the error: Operator '+' is not defined for types 'ControlesModificados. ControlesModificados.JQDialogEventHandler' and 'ControlesModificados. ControlesModificados.JQDialogEventHandler'. How can i write this code "commandHandler -= value" in other way so the error goes away! or how can i defined those operators for the eventhandler.
Namespace ControlesModificados
Public Class JQDialogButton
Inherits Button[code]....
As you can see the DialogCommand is using another JQDialogHandler, so i can't just use
Public Custom Event DialogCommand As JQDialogEventHandler

I have a Windows Form application that has a global error handler to display unexpected errors.
Namespace My
Class MyApplication
Delegate Sub ProcessParametersDelegate(ByVal sender As Object, ByVal args() As String)
[code]....
1) for the same deployed code, I SOMETIMES get line number in the displayed StackTrace error message and sometimes do not, even when the error message includes source code that I have written rather than a referenced binary. The project is compiled with a DEBUG configuration.
2) The application strangely minimizes to the tray when the error occurs (I thin it is unlikely that anyone can diagnose this issue w/o my more code posted, but I'll mention it anyways)
3) When I try to intentionally raise an error by, for example, dividing by zero hoping to test by global error handler, I get a dialog error message from the interactive debugger rather than jumping into my global error handler (which i want to debug because there is more to it than I posted.) Do you have any idea how to triggerand force teh execution of the global event handler?

I began setting up a TeamCity server a couple days ago for use in automated testing and CI. We mainly do VB.net web apps and up until now, it had been checking out things and building just fine.
A problem came up when I tried to add actual deployment into the mix. I saw this article: [URL]
referenced all over the place as a good guide, so I followed the steps relating to setting up a Web Deployment project and rigging TeamCity to run it. Basically, it recommends setting up a new build configuration in VS2010 called "Deployment" which builds the Web Deployment project, then creating a build configuration in TC that targets it.
The issue is that the web deployment project won't compile when run under TeamCity. The regular build works just fine, but if I set MSBuild to use the build configuration that includes the Web Deployment project, it crashes halfway through and gives an error about attempting to load the System.Data.OracleClient assembly in an incorrect format. I assume this means a 32-bit/64-bit error, especially since my development machine is a 32-bit box, and the build server is 64, but I don't know why this is happening, especially when the regular build works, and nothing in my project involves using an Oracle database.
I saw in the log that there's a warning about missing reference assemblies for the 4.0 framework, so I headed off to the MS website and downloaded the SDK, but that didn't change anything. At this point, I'm stuck, and I didn't see anything already here on Stack Overflow that looked quite like this. I'll attach the log below. Have I missed something simple?
[10:46:05]: Project "MyTools.sln.teamcity.patch.tcprojx" (TeamCity_Generated_Build target(s)):
[10:46:05]: [Project "MyTools.sln.teamcity.patch.tcprojx" (TeamCity_Generated_Build target(s)):] Project "MyTools.sln" (Rebuild target(s)):

I have written a program that if all if statements are true then it closes out with me.close() without displaying the form. If a if statement is false, then the form shows with some text as to why it failed.The program works perfectly....until I change the form setting "top most" to true, if the if statements are true, instead of the form closing as it should, I receive ObjectDisposedException was unhandled Cannot access a disposed object. Object name: 'Form1'.

I know that
Public Incognito As Boolean
is a variable called "Incognito" that is class-wide that is a boolean.My question is that is there a form-wide variable form that can like communicate with different forms. So if a variable in form1 is "True" than, how can you make a variable in form2 turns to "True" too?
