Hi:

I'm new to vb.net. I'm programmer of VB6

I'm trying to add new record to sql table called "Users" and have an error message.

The Code used is;

        Dim strQuery As String = "Select * From Users"
        Dim ds As New DataSet("Users")
        Dim da As New SqlClient.SqlDataAdapter(strQuery, dbConn)
        da.Fill(ds)

        Dim dr As DataRow = ds.Tables(0).NewRow
        dr.Item("USER_ID") = "data"
        dr.Item("PASSWORD") = "data2"
        dr.EndEdit()
        ds.Tables(0).Rows.Add(dr)
        da.Update(ds, "Users") '****>>> Update unable to find TableMapping['Users'] or DataTable 'Users'.

Thanks in advance for your help.

Instead of DataSet("Users")
try
Dim dt as New DataTable("User")

Also, sometimes you have to use a different name from the actual database table for the datatable or dataset.

This is assuming that the there is nothing wrong with the dataadapter.  But make sure you replace ds for dt.

It looks like you didn't specify an UpdateCommand and an InsertCommand for the data adapter.  You can use an SqlCommandBuilder to do that from the SelectCommand.
