.net - OleDBException Was Unhandled
Apr 9, 2010
I am trying to debug my program and I am getting an OleDBException Was Unhandled. It then goes to the path where the error is located. The executable is listed in the bin file and I have re-built and built the application several times. The application is supposed to extract data from an external MS Access database. Note my code:
Public Class frmSpanishFoodStoreInventory
Private Sub StoreInventoryBindingNavigatorSaveItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StoreInventoryBindingNavigatorSaveItem.Click

Dim conn As New OleDb.OleDbConnection
Dim ds As New DataSet
Dim da As OleDb.OleDbDataAdapter
Dim sql As String
[code]....
The above code stops running at the point of the da.fill line with the error that the specified table does not exist.In my limited knowledge so far to me it looks like the operators table exists as it showing in the Solution Explorer.

My program reads a 3rd party data text file and I give the user the ability to add a row. The problem I am having is one users text file contains an extra tab at the end of each datarow thereby creating an extra column when i view it in DataGridView it gets labled "NoName"
Moving foward I get the following error upon trying to isnert a new datarow. The INSERT INTO statement contains the following unknown field name: 'NoName'. Make sure you have typed the name correctly, and try the operation again.

Using OLE and Jet, you may receive errors when saving system dates and times to databases in different regions.Consider what happens when saving dates and times returned using the Now() function in Canada or the US: the date string "#2010/02/03 08:59 AM#" will save fine. If using 24 hour time, the string "#2010/02/03 08:59#" will also save fine.
If you change your system region to Spanish (Peru) or Spanish (Mexico), the ante meridiem changes from "AM" to "a.m." (or "p.m."). The date string becomes: "#2010/02/03 08:59 a.m.#"Note that this will NOT save correctly to the database and throw a System.Data.OleDb.OleDbException. The workaround we use is: Public Function clean_date(ByVal strDate As String) As String Dim str_buffer As String

I have a VB.Net program that reads in a flat file, and then parses line by line, formatting the data into different spreadsheets in an excel workbook (each line can be any 10+ different record types so I parse and put in appropriate excel sheet).
For smaller sized flat files (under 10mb), the parser works great. However, I am trying this on a file that is over 120mb (400k+ lines). While running, I will get an OleDBException saying that the spreadsheet is full. Now I am pretty confident that Excel can handle a much larger data set than a flat file. So I assume this exception is not giving me the true story as to what is really occuring.
I open a connection, and then parse each line in the file, inserting each row into the excel file. I assumed it would be bad performance wise to open/close the connection between each insert. Could this be causing the issue? Any ideas what I need to do to handle such a large file? There are cases where the flat file can be over 500mb.
To actually do the insert into excel, I am just doing the following (I construct an sql query based on the type of row and values parsed):
Dim conn As New OleDbConnection()
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExportLocation.Text + "" + importFileName + "-PVF.xls;Extended Properties=""Excel 8.0;HDR=YES"""
