I am a newbie and am trying to open a table in SQL Server 2008 table from Visual Basic using ADO and its throwing up a weird fatal error. The error message is:'A fatal error has occurred and debugging needs to be terminated. For more details, see the Microsoft Help and Support web site. HRESULT = 0x80131c08. ErrorCode: 0x0' The code I am running at the time is:
[Code]....

Dim ExcelConnection As System.Data.OleDb.OleDbConnection

I'm creating a tool that will query Excel and intialize the default settings for the site's Cad Software.I want 2-20 users to be able to simultaneously query excel. Currently I have the spreadsheet open on one computer and the other test machine gives me this error.
GetOleDbSchema Table Require an open and available connection. The connections state is closed.
I could use some help on the code design. Should I use Datareader instead....Does that have less permissions issues? Or do I need to open up the oledbconnection in a different manner?

View 2 RepliesI am writing a program to record patient info for a local ambulance company. My problem is when a patient is added it does not write to the SQL server. When I open up the table in the Management Studio the record is not there. Here is the other thing that is weird to me. I open the program, add the patients info, clear the search box, type in their info and the record shows up. When I close and reopen the program I search the same record and nothing comes up. I tried redoing the string command, then thought maybe I needed to use parameters but that didn't work either.

I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.

I'm able to pull every piece of information I need from the error message except the name of the parentTable. I've already determined that the SqlException doesn't store the statement that caused the exception, and as far as I can tell it doesn't store information about the name of the parent table, only the table that is trying to reference it.
Is there an easy way to get the name of the parentTable?
