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?

VB 2008 Dataset Error : "A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll"

Sep 27, 2008

I am trying to perform a simple bound connection between an Access database and a text box on a form. This is actually Chapter 18 of the "Microsoft Visual Basic 2008" book.I get the same error message when trying to create my own project "MY ADO Form" or the "ADO Form" project supplied from the DVD provided with the book. I am running the 90 Day Trial Version of Visual Studio 2008 with SP1 and Net 3.5 SP1.

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.

An Unhandled Exception Of Type 'System.StackOverflowException' Occurred In Mscorlib.dll?

Apr 1, 2009

I am Using Visual Studio 2008 Express edition (.NET Framework 3.5) ... I got this Error when Using A recursive Call To a Function .. I have 3 Background Workers Which Select Data From Database With Status =0 , Take The file Name And File Path Asssosiated With That record, and Then Copy it to other place and on successful completion update the status to 2 otherwise to 3 . and again searech for other record having Status 0 and so on ..

i made a method for selection of record from database every worker call this function . Now I have a check when dataset is filled i checked is there any row ? if yes then it do the rest of work otherwise agin call it self to search for the record...ECURSION.. In Case of records with status zero , It works Fine But in Case of no records Which have status zero it recursively calls itself For approx 1.5 mints and then throws The Exception That " System.StackOverflowException occured in mscorlib.dll at line "DataAdapter.Fill(Dataset,Table)" . I have no Idea what to do with this ..

Eventhough I have Encloesd It in Try...Catch Blocks but It didnt Cath It .. I serached The Internet and msdn social help for it and i found that it occurs most with infiniteloop or Infinite Recursive calls. i know it is due to my recursive call to the SelectData Function But i have no option without it?And One thing more that this project i mean the exe of this project is concurrently runs with another project Which add data to the databse about Filename Filepath and status =0 for Fresh entry..

I have several ActiveX controls in my project one of them loads solidmodeling files for viewing. Because this process can take some time the authors provided an OnFinishedLoadingDocument event.This worked fine under VB6.Now however under VB.NET 2008 framework 3.5 I get an exception thrown When I try to access a form control from this event.
