Nov 9, 2009

Asp.net - Reading CSV File With OLEDB Ignores First Line Even With HDR=No In Connection String?

Jan 4, 2011

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)

The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:

Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")

[code]....

The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.

Invalid Connection String When Modifying Tableadapter Connection?

Jan 19, 2011

I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.

For the gist of the application:

In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.

I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.

Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim DBConnStr As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security

2010 OleDb Text Connection String: "Not Valid Path"

Nov 7, 2010

I've been all over the help files and finally patched together a VB OleDb connection string for delimited text files:

Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""

"fName" is passed in by an open file dialog.In every case (for all paths) it throws: 'C:1_2010NormalFileNormal.csv' (or where ever it is pointed) is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.Since no path works, it must be a syntax error, but I'll be darned if I can see it.

Full code of this routine is:

Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
Dim conn As New OleDbConnection(connection)
