Hi, I already posted this but can't find it anywhere!

I'm having a problem that seems very simple. I'm trying to updatea db and am getting stuck on the data binding of a textbox. Iget a "Cannot bind to property or column permitnumber onDataSource" OR if I use ("text", ds, "permits.permitnumber")nothing happens except that a permit number that already existsshows up in the textbox. Do I have something in the wrong order?HEre is my code:

Dim dbConn As NewOleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:\Projects\Tests\ParkingPErmits.mdb")
Dim da As New OleDbDataAdapter("select * from permits",dbConn)
Dim cb As New OleDbCommandBuilder(da)
Dim ds As New DataSet

da.UpdateCommand = cb.GetUpdateCommand
da.DeleteCommand = cb.GetDeleteCommand
da.InsertCommand = cb.GetInsertCommand
da.Fill(ds, "permits")

txtPermits.DataBindings.Clear()
txtPermits.DataBindings.Add(New Binding("text", ds,"permitnumber"))

da.Update(ds, "permits")

Thanks!
 
use the second syntax that you mention ("permits.permitnumber") and call
EndCurrentEdit before you call Update.

Read my answer to your first question first b/c it's there's another issue
as well.
