We have just converted a large VB6 desktop app to VB.NET 2008. First via the VB 2005 (opened the project), then days of fixing errors, etc. Then opened the VB 2005 in VB 2008 so now it is a 2008 solution. There are about 30 forms with code behind and about 40 other modules.

We have just converted a large VB6 desktop app to VB.NET 2008. First via the VB 2005 (open project), then days of fixing errors, etc. Then opened the VB 2005 in VB 2008 so now it is a 2008 solution.The more we try to test the worse it gets. It did start and crash with typical errors but now it does not even get off the ground.[code]The more we try to fix the earlier it crashes. The 1st form load does not even start (break point not stopped on but it did before and failed on AppFrameWorkOn = True where AppFramWorkOn is just a boolean in another module.Except same code works in other programs.We have written several dozen other VB.Net 2005 programs but this one just doesn't make sense.There is also no Configuration Manager in the Build menu.
View 11 RepliesThe Type Initializer for <Module> threw an exception?What does this error mean.
View 11 RepliesWe have a VB .Net windows application developed with VS 2005, framework 2.0.
The executable when run on a different machine throws the above error. It cannot be caught with the IDE due none of the developers experiencing it.
I have project which is implemented in VB.Net using VS 2008. I install build on Win 7 64 bit machine an see a splash screen after which it thorws exception saying "The type initializer '<class name>'for threw an exception". The class is NotInheritable and the method which I'm trying to access is shared. The same project works fine on win 7 32 bit machine. The build is also compiled using x86.
View 2 RepliesI am creating a medium/largish program in VB Express 2008. To keep it more simple i have created each section of the program in individual projects/solutions and then when they all work well, copy the code from each project into one Big project. Everything was fine, but when i put the global variables all together in 1 module, i get the following error:'The type initializer for 'WindowsApplication1.Module1' threw an exception.' This appears everytime a line of code is ran that reads/writes to a var in the module.

I've been writing an application, and all has been going smoothly; I tried to debug my application, after many previous debugging sessions and from nowhere, I received an error. I've not changed the module in which the error is coming from, but I can't narrow the error down either.
Here's the error: The type initializer for 'HG520b.MHProgramming' threw an exception.
This occurs any time I attempt to debug my application and linked to a function, property or enum which resides in my module.I don't know where to start looking for this error seen as it's all random...

I'm using express 2008 build the windows app. and in the app, it calls a webservice which was built by VS2003.It works fine on most PCs. however, there is one PC, it always shows this error:
System.TypeInitializationException: The type initializer for 'System.ServiceModel.ClientBase' 1' threw an exception
....
System.configuration.ConfigurationErrorException: Configuration system failed to initialize ---> System.Configuration.ConfigurationErrorsException:
Unrecognized configuration section system.serviceModel
.....
however, the configuration file was generated by express 2008, and it seems there is no error.
I encountered this exception when I trying to load a certain page. It doesn't show me which line of code has problem, which makes me kind of dizzy now..What is a type initializer? What is it used for? and how can I troubleshoot this problem?
View 1 RepliesException Message happens when my splash screen shows: The type initializer for 'App_Name.GlobalThings' threw an exception GlobalThings is not a class, but just a module name (Module Globalthings). I get the error above at run time (.exe) but not during debug.Because I am brand new not only to visual studio and to visual basic, but also to programming, I have no how to figure out what is actually throwing this error since it occurs only at run time.

View 1 RepliesIs there a way I can catch and handle two different exceptions within the same exception type? For example:
Try
' My code
Catch ex As System.Net.WebException

I have 2 different exceptions that are System.Net.WebException. I want to handle them different ways. Problem is the catch block above catches them both. Is there a way I can determine if which of the two it is and handle them differently?
I have a large project where we have 2-3 dll projects that are converted from VB6 to VB.NET. We have fixed all the issues that caused compilation errors, and most of obvious issues in running, so now we have basically a program up and running. The exe is created from scratch in VB.NET, using a lot of functionality from the converted dll's (including GUI forms). What I wonder is when I run the program in debug mode, I get a bunch of warnings in the "Immediate Window" saying:
A first chance exception of type 'System.Exception' occurred in Microsoft.VisualBasic.dll
...and some of other type (but most of them in Microsoft.VisualBasic.dll).I was wondering if this is common in projects converted from VB6, or if it is caused by bad design in our code...
I'm trying to catch a user defined permission exception - i.e. a user does something their level of system access won't allow, permission exception is thrown. My problem is, the exception is caught and then rethrown as a genertic System.Exception.Is there any way I can deduce the original exception type, without resorting to string comparisons, like if ex.ToString.Contains("Permission denied"
View 2 RepliesWhen catching an exception in .net, you can have as many type-specific exception blocks as needed. But I usually try to have at least one "general" exception catch block. But is there a way to get the type of the "real" exception thrown that is caught by the generic exception handler, perhaps using reflection?For example, if I have
Catch ex As System.ServiceModel.FaultException(Of InvalidUser)
ProcessModuleLoadException(Me, ex)
Catch ex As System.ServiceModel.FaultException(Of SQLExceptions)

I just tried to run a project of mine that has a wpf control in it and i get the error:Exception of type 'System.ExecutionEngineException' was thrown.The error automatically closes after about 3 seconds When I create a new WPF project visual studio closes down - no error messages, also just closes with no errors if I create a form application and add a WPF control to it. Also compiled applications just bring up the "xxx has stoped working" error - even apps that are not mine such as Microsoft Pivot that use WPF?

View 2 RepliesI have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
I am using VB.NET 2005 to create a Windows forms application. I have a procedure named SendMail that creates an instance of Outlook.Application, to send an email from my application. I found the code on this forum, I think.The procedure works fine, but I can't use error handling with it.I call the procedure from a button click event.
