View 1 RepliesUniversal Way To Connecting To Excel Through OleDB Connection?
Nov 17, 2011A While back I developed a application that connected to Excel using DB connection. It worked fine since the application was designed for usage on one particular PC with Excel 2003. I especially liked the solution since the data retrieval was much faster compared to what I would get if I connected to Excel using Interop libraries.
However, recently when I tried to implement the same solution onto another app that would run on various PC that could use different versions of MS Office I ran into multiple problems. First of all, I can't use the same connection string on various versions. Also, the whole x64 vs x86 thing is adding to the problem.
I wonder if there is a way to check the version and use the apropriate connection string for every version?

Asp.net - Reading CSV File With OLEDB Ignores First Line Even With HDR=No In Connection String?
Jan 4, 2011We'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.
Efficiency Of Oledb - Got 10+ Users Using Files, Via A Oledb To Put Info Into An Excel Spreadsheet
Oct 18, 2010Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

Nov 7, 2010I'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)

Difference Between Oledb Connection And Odbc Connection?
Nov 9, 2009i want to ask what is the difference between oledb connection and odbc connection. I have a case, my office used ncomputing then i have to developed an application using sqlserver 2000 and vb.net 2005, i used oledb connection.

But there's a rumor that when using odbc connection, we dont need to give admin access level for users.es.
