Question

I’m currently working on an ms access database in vb.net.
And I need a code that can determine which data I am updating in the database. Because when I try to update the data, the previous data is being cloned and it will generate two data(the updated and the previous data), and the program will also generate a random id number for the updated data, which is not good.
Here is my code for the update button:
‘update
Dim cb As New OleDb.OleDbCommandBuilder(da)

    ds.Tables("GH").Rows(INC).Item(1) = TextBox13.Text
    ds.Tables("GH").Rows(INC).Item(2) = TextBox14.Text
    ds.Tables("GH").Rows(INC).Item(3) = TextBox15.Text


    da.Update(ds, "GH")

    MsgBox("Data updated")

My code for form load:
con.ConnectionString = “Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\ACCESS DATABASE\search.mdb”
con.Open()

    sql = "SELECT * FROM GH"
    da = New OleDb.OleDbDataAdapter(sql, con)
    da.Fill(ds, "GH")
    con.Close()

I’m using system.data.oledb namespace

Here are my declarations:

    Dim cmd As OleDbCommand
    Dim cn As OleDbConnection
    Dim dr As OleDbDataReader

    Dim ds As New DataSet
    Dim con As New OleDb.OleDbConnection
    Dim da As OleDb.OleDbDataAdapter

Your question is not clear to me at all, but if you want to find the last ID of an insert, you would usually check the results of “SELECT @@IDENTITY” immediately after the record is inserted.
