A First Chance Exception Of Type 'System.Data.SqlClient.SqlException' Occurred In System.Data.dll
Jan 22, 2009
I am just trying to get the system to open a database and I get this error:
A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in System.Data.dll
here's the entire code of the main form
=======================================
Imports System
Imports System.Data
Imports System.Data.SqlClient
[code]....
the error is generated at the open method note* this same code works fine in another computer, the main difference is that this one has a 64 bit OS.

I've spent a substantial amount of time trying to figure this out, but I keep getting the same error
A first chance exception of type 'System.Data.OleDb.OleDbException' occurred in System.Data.dll
A first chance exception of type 'System.NullReferenceException' occurred in project1.exe
This happens when I try to use the DataReader.my code is
Public Function Identification() As List(Of Integer)
Dim returnIndex As New List(Of Integer)
Dim dbCount As String = "SELECT Bookingid FROM bookdetail WHERE Date =" & getCurrentTimeString() & " 12:00:00 a.m."
Dim count As Integer = 0

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?

Do While rdr2.Read()
Dim var1 As String = rdr2.Item("Week").ToString
Dim var2 As String = rdr2.Item("L1").ToString
Dim var3 As String = rdr2.Item("L2").ToString
It generates the following error: A first chance exception of type 'System.Data.SqlServerCe.SqlCeException' occurred in System.Data.SqlServerCe.dll
Interestingly, if I use a numeric value for the variable it for LSArraytemp, it writes to the database no problem at all.

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.

Brief of my project: Taking attendance using RFID reader and RFID passive tag. Main tasks:
1) Scan a Tag and Tag ID is transmitted to GUI.
2) Tag ID is matched with Student ID in database.
3) Successfully matched Student ID is displayed on GUI and LCD.
When i had experienced this problem, student ID was only display on UI but not LCD. After that, my system hang. This happened only when the data of tag scanned is taken from text file through OpenFileDialog. Manually add of data via UI just work fine.

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.

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 get this message each time I run the appA first chance exception of type 'System.NullReferenceException' occurred in <Applicaton>I have isolated the key Subs which seem to upset it, but I cannot for the life of me figure out what it is about it that's upsetting it.

I'm converting another project from VS2003 to VS2010 and am getting this message in the Immediate Window before I hit my MyBase.Load. From the warning, it looks like somting is undefined yet is being used - causing an exception. How can I trace this down?My app uses 2 DLLs, could the msg be coming from them during their load?

My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application.
