I am trying to make an oledb connection to an Access database.
1. I added a component class.It said drag from the toolbox to add components.
2. I dragged over the Oledbconnection and OledbdataAdapter
3. I clicked on new connection string for the oldeb Connection and try to connect to the SHX.mdb datababase in the debug/ bin folder I don't have a username or password for the database and do not want to set one up.( is this possible in .net?)
4.As soon as I try to test the connection, I get the "invalid authorization specification" message. I can't get past this and do not really understand why I am getting this message.I have vb 2005 standard edition, not express edition.The exact same thing happens when I try to set up the data adapter to the shx.mdb database.
I am on XP2 and not logged in with a password or username. Could this be the issue or is there something else I am overlooking.Also, since I am coming from vb6 and ADO is there anyway to just write the code without having to use datasets, adapters and oledb connections to bound controls?

im trying to write to an sql database. im inserting an image, as well as some other information. I am using the following code which works fine, as long as i do not add an extra column/variable "LOCATION" in to the mix and leave "
'Cmd.Parameters.Add("@LOCATION", OleDb.OleDbType., 3).Value = "testing"
commented out. *this is undesireable as im trying to add extra criteria to be saved like LOCATION.
Try
Dim st As New FileStream("\serverfolder1storage" & "pdftemplate.jpg", FileMode.Open, FileAccess.Read)
Dim mbr As BinaryReader = New BinaryReader(st)
Dim buffer(st.Length) As Byte

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

I've recently made another question about connecting to MS-ACCESS database with .NET in C# or VB.NET. It worked just as intended with MDB, but with accdb it caused an exception in
conn.Open();which follows:
Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.

I have created an auto emailer to distribute our work routes for my colleagues. Problem is I made it easy for the management team to update the list. List is ordered by Tech Number, First name, Last name, Email address.
I have coded this in VB.NET 2008 using Database sources and drag-n-drop the table on the form. I let VB do most of the coding of the connection and text boxes. (IE If (Tech_TextBox.Text <> "9999") Then)What I would like to do, instead of using a bogus tech number as an exit. I need an 'IF Then" or 'DO UNTIL' after last record.

The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

I created a connection to a Microsoft Access database by using the wizard. Now in the server connections I see my data connection to the db. I'm trying to create a method to compact the database, so I used JRO to do it. To do it however, an exclusive access is required, and when I try to call the method I get an exception.

My query is not the straightforward connection to MS Access.I am using a third application that places all data in an Access database BUT recently they changed the database so that it doesn't end in '.mdb', instead in another suffix: '.accdb'.The database is still an Access database but I cannot connect to it using the connection strings:[code]Previously I was able to use the second connection when the database name ended in '.mdb' (Database Name.mdb).
