I am working on a code that will import data into excel. Once I add the following piece of code I get aSystem.TypeInitializationException was unhandled error. The program stops and breaks in the form where I call my main (which starts the main as soon as the form opens). Does anyone see why this pice of code would cause this error?
#Region " (Import Data) This function will import the PI Tag Names and desired Attributes into an Excel worksheet "

My MSSQL 2008 and VS2005 were corrupted out of sudden. I had reinstalled .net Framework 2.0, .net Framework 2 SP2, MSSQL 2008 and VS2005.
After installation and without any code modification, I tried to debug the program and I got the below error message.An unhandled exception of type 'System.TypeInitializationException' occured in Production.exe.Additional information: The type initializer for 'Common' threw an exception.
I have run my program a thousand times throughout its creation and have never had a problem. I entered some code for a NumericUpDown control, and now I get this error whenever a variable is assigned a value. The code for the NumericUpDown control doesn't contain anything, really. No new variables, nothing. If I take the code out, the program works just like it did a thousand times before. What gives?
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.
Here is the code I am working with, everything works fine up until last line then i get evaluate exception unhandled "Cannot perform '=' operation on System.Int32 and System.String." My eyes are going blind trying to figure out whats wrong, if I understand correctly it cant count system string and REO is a string value.
The thing i have done this before ,count that is. I know you cant average strings and some other function but i have been able to count.

I made a program with Visual Basic Express 2008. I got this error message when I try to close my program after running it. (PS: It is a simple code that can login into Microsoft SQL Server)The error message shows the error was caused by the "system.drawing" (Parameter is not valid). Also, I have been trying the code in VBA (Excel). When I tried to close Excel after running my code, I got the same problem (Microsoft Excel has encountered a problem and need to be closed.....) and the error report shows the error was caused by "system.drawing" as well.

How can I catch this TypeInitializationException? Don't really care if it is C# or VB.NET code. Here is some sample code of what I am trying to figure out (this is not real code - just something to show what I am dealing with):

Now I know why it is throwing this error but nothing I do will stop it from showing up.At the top of our form we have a module that we use to check if a file exists on the computer and if it doesn't then it will create the file.I have tried accessing that module from the form load event but with no luck as it still throws the error.
