dataset problem

hi all

I fill my dataset from two different databases using odbc and sql adapter. But i need to update my parodox table data with data from sql table.

which way o method i need to use . i have no idea :(

my code to load data works and returns result

vb.net Code:

' load data to dataset
 Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
        Dim s As String
        s = "DRIVER=Microsoft Access Paradox Driver (*.db);UID=admin;" & _
            "UserCommitSync=Yes;Threads=3;SafeTransactions=0;ParadoxUserName=admin;ParadoxNetStyle=4.x;Paradox;" & _
            "NetPath={0};" & _
            "PageTimeout=600;MaxScanRows=8;MaxBufferSize=2048;" & _
            "FIL=Paradox 5.X;DriverId=538;" & _
            "DefaultDir={0};" & _
            "DBQ={0};" & _
            "CollatingSequence=ASCII"
             s = "FILEDSN=paradox.dsn"
        Dim c As String
        c = "server=serveris;user id=sa;password=mypsw;Database=database"
        Dim sSQL As String
        Dim d As New DataSet()
        Dim f As New DataSet()
        ' Load the target data and name the table
        Dim oConn = GetNewConnection()
        sSQL = "SELECT f1,f2  FROM  test1;"
 
        Dim adapter As Odbc.OdbcDataAdapter
        adapter = New Odbc.OdbcDataAdapter(sSQL, s)
        adapter.TableMappings.Add("table", "test1")
        d = New DataSet()
        adapter.Fill(d, "test1")
        d.AcceptChanges()
        ' Load the source data, set table name and PK
        Dim cSQL As String
        ' Create and open a new connection to local backup MDB
        Dim Conn = GetNewConnectionSQL()
        cSQL = "SELECT f1,f2  FROM test2;"
        Dim cadapter As SqlClient.SqlDataAdapter
        cadapter = New SqlClient.SqlDataAdapter(cSQL, c)
        cadapter.TableMappings.Add("table", "test2")
        f = New DataSet()
        cadapter.Fill(f, "test2")
       d.Merge(f)
        datagrid.DataSource = d
 
           End Sub

What can i do to save data from test 2 to test1 table ?? please give direction
Thanks .

Please use the appropriate code tags when posting code to improve readability.

As far as a DataAdapter is concerned a DataTable is a DataTable is a DataTable. The DataAdapter doesn't care in the slightest where the data in the DataTable came from. This code:

vb.net Code:

adapter1.AcceptChangesDuringFill = False
 
Dim table As New DataTable
 
adapter1.Fill(table)
adapter2.Update(table)

will work fine as long as the second DataAdapter has the appropriate InsertCommand. Note that that first line is crucial to ensure that all the DataRows appear to be Added so the second DataAdapter knows to insert them.
