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...

An Unhandled Exception Of Type 'System.TypeLoadException' Occurred In Unknown Module

May 10, 2011

I have recently updated a legacy compact framework application to support Windows Mobile 6.5 but after going through my backwards compatability testing I have an issue with the WinCE 5 device.When attempting to run the application from both the EXE and the debugger I get the "An unhandled exception of type 'System.TypeLoadException' occurred in Unknown Module." exception but its not giving me any idea which dll / type it has issue with.The changes do work on the Windows Mobile 6.5 Motorola device and the Pocket PC 2003 Psion Device but not on the WinCE5 Psion device.Does anyone have any ideas how I can find out which reference is causing me the issue. I have tried removing the new references to the Symbol barcoding and imaging libraries but I am still getting the same error.OK, it looks like the .Net Compact Framework installation had corrupted some how. I flattened the device, reinstalled and everything appears to be working.

And ever since, the shapes make errors and I can't change there colors. I've tried reinstalling VS 2010, and changing refferences doesn't work anymore.

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?
