My friend, you need to look into .ExecuteNonQuery and .ExecuteReader objects of the Class OleDB.
It's here you can execute SQL queries to your access database.
an example:
Public Sub ACNonquery(ByVal utos As String)
Dim Accessconn as new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\DELL-PC\Desktop\OnlineDB.mdb")
Dim sqlcommand As New OleDbCommand(utos, accessconn)
Try
accessconn.Open()
sqlcommand.ExecuteNonQuery()
accessconn.Close()
Catch ex As Exception
accessconn.Close()
MsgBox(utos & vbNewLine & vbNewLine & ex.ToString)
End Try
End Sub
call it like this:
ACNonquery("insert into tablename values('data1','data2');")
In this example, I used the NonQuery to execute an SQL command (in this case, an insert) to my access database.
