Dataset table row count - OLEDB Data Source

The DataSet contains copy of the data we requested through the SQL statement. The DataSet consists of DataTableCollection and their DataRelationCollection. The DataTableCollection contains zero or more DataTable objects. The data inside Table is in the form of Rows and Columns . The following VB.NET source code shows how to find the number of rows in a table that resides in the Dataset from OLEDB Data Source.




Imports System.Data.OleDb
Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim connetionString As String
        Dim connection As OleDbConnection
        Dim oledbAdapter As OleDbDataAdapter
        Dim ds As New DataSet
        Dim sql As String

        connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
        sql = "Your SQL Statement Here"

        connection = New OleDbConnection(connetionString)
        Try
            connection.Open()
            oledbAdapter = New OleDbDataAdapter(sql, connection)
            oledbAdapter.Fill(ds, "OLEDB Temp Table")
            oledbAdapter.Dispose()
            connection.Close()

            MsgBox("number of Row(s)   -   " & ds.Tables(0).Rows.Count)

        Catch ex As Exception
            MsgBox("Can not open connection ! ")
        End Try
    End Sub
End Class

connetionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Your mdb filename;"
sql = "Your SQL Statement Here"

You have to replace the string with your real time variables.
