Type Initializer For Threw An Exception

Aug 15, 2011

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.

Error: The Type Initializer For 'HG520b.MHProgramming' Threw An Exception

Jun 22, 2012

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...

Error - A First Chance Exception Of Type 'System.Exception' Occurred In Microsoft.VisualBasic.dll

Sep 2, 2009

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...

Error: A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll

May 5, 2011

I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work.  It will all work fine until I attempt to run or debug the project.  The data will not show up.  The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll

As I said, the project seems to build fine, but it will not pull the data.  After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?

My operating system is the 64 bit Version of Vista with all updates.The error when I try to run the application in the debug mode is:"A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll"and as a result no data shows up in the text box from the database and the data selection bar is grayed out in the form.  The underlying database "Students Data Set" appears to be fine as I have seen the correct data for the fields "Instructor" and "PhoneNumber" prior to running the program and when connecting with the database.
