I need help for connecting to Ms access database

[mojal67]

Hi ,I work with vb.net 2005 . I want to know if I want to connect to data base with Ms Access which data source i can use (ODBC or OLEDB)
I write the following code in form load event (by OLEDB) :

Dim conn As New OleDb.OleDbConnection("Jet OLEDB:Global Partial Bulk Ops=2;Jet OLEDB:Registry Path=;Jet OLEDBdatabase Locking Mode=1;Jet OLEDBdatabase Password=;Data Source=C:\Program Files\Microsoft Office\Office11\Samples\Northwind.mdb;Password=;Jet OLEDB:Engine Type=5;Jet OLEDB:Global Bulk Transactions=1;Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:System database=;Jet OLEDB:SFP=False;Extended Properties=;Mode=Share Deny None;Jet OLEDB:New Database Password=;Jet OLEDB:Create System Database=False;Jet OLEDBdon't Copy Locale on Compact=False;Jet OLEDB:Compact Without Replica Repair=False;User ID=Admin;Jet OLEDB:Encrypt Database=False")

Dim da As New OleDb.OleDbDataAdapter("select * from orders", conn)
Dim ds As New DataSet
da.Fill(ds)

and have an error that "OledbException was unhandled"
How can i solve this error or How can connect with ODBC data source to MS access data base.
I will happy if anyone can help me.
Thank You , MOJAL

Two things. Use the IDE to get the correct connection string. It seems a bit long with a lot of unnecessary options for Jet Database. Then make sure you ALWAYS put your connection in a Try/Catch block. This is the only way to handle exceptions.

try changing the code to

Dim conn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\somepath\mydb.mdb")

if it still doesn't work, you might have the wrong path for your database file.

try something like this......

Private currpath As String = System.Environment.CurrentDirectory
Private connService As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source= " & currpath & "\ServiceCalls.mdb")
Public daCustomers As New System.Data.OleDb.OleDbDataAdapter("Select * from Customers", connService)
Public daCalls As New System.Data.OleDb.OleDbDataAdapter("Select * from Calls ORDER BY CustomerID", connService)
Private daCallStatus As New System.Data.OleDb.OleDbDataAdapter("Select * from Status", connService)
Private cbCustomers As New System.Data.OleDb.OleDbCommandBuilder(daCustomers)
Private cbCalls As New System.Data.OleDb.OleDb

Hi:

I missed to see that the code needs to be typed in the Form Load window. Thanks Mojal. But I hope to keep in touch with you folks to discuss more about VB.NET and Access.

Thanks,
