I can pretty much follow the code, but I don't understand what updateably
query it is referring to.
Line 75: adapter.Update(ds, "TMaster")
I have a single MS Access 2003 DB with a single table TMaster and Four
columns (PK, FirstName, LastName, EmpID). I am only pulling the data for the
PK and FirstName for my testing purposes (See SQL Statement in code).

</html>You didn't define an update query for the adapter to use. It doesn't know
how to do the update on its own.
You either have to supply the update command, or you have to use an
OleDBCommandBuilder object. If can do some research on both these techniques
for more information.

The most common problem asociated with the
"Operation must use an updateable query" error message is that the
account you are using doesn't have read/write permissions to the
directory and/or Access database file which you are trying to modify.

I remember having such issues when I was working with classic ASP and in
most cases it was security permissions on the access DB. Because of that
prior experience, I made sure to check the permissions before I posted and
security permissions are full control for all auth users on our network, and
I'm an admin so have full control anyway. I double check again this morning
to make sure and I still get the same error. I'm at a loss.

Hi Marina.
Under the Update subroutine:
Public Sub Update(ByVal PK As Int32, ByVal FirstName As String)
Dim objConnection As OleDbConnection
Dim strConnection = "Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=e:\hhsinternal\tests\editing\edit
ing.mdb"
If objConnection Is Nothing Then
objConnection = New OleDbConnection(strConnection)
End If
If objConnection.State = ConnectionState.Closed Then
objConnection.Open()
End If
Dim strSQLSelect As String = "SELECT PK, FirstName FROM TMaster"
Dim adapter As New OleDbDataAdapter(strSQLSelect, objConnection)
Dim ds As New DataSet()
adapter.Fill(ds, "TMaster")
objConnection.Close()
Dim tbl As DataTable = ds.Tables("TMaster")
tbl.PrimaryKey = New DataColumn() _
{ _
tbl.Columns("PK") _
}
Dim row As DataRow = tbl.Rows.Find(PK)
row.Item("FirstName") = FirstName
Dim cb As New OleDbCommandBuilder(adapter)
objConnection.Open()
adapter.Update(ds, "TMaster")
objConnection.Close()
End Sub
You can see that I have the cb OleDbCommandBuilder object, although I don't
know if it is being used correctly. Is there more needed to that?

Jim are you giving the ASPNET acct the right permissions?

Well I'll be ...
This is the first time I've actually messed with an access DB and ASP.NET so
I never thought I had to verifiy ASPNET account permissions. That was it
exactly.
Most of my DB programming thus far in ASP.NET has been with SQL.
Thanks Patrick.
