This is kinda weird, I have stripped the code to it's bear bones and still it's not doing what it used to do... maybe I cant see the woods for the tree, but I cant see what I have done wrong - : Basically, I am calling out data from a SQL server - pulling it through a loop, in this example just doing it on an mdb file... I created a button that when pressed it exported the data to a *.txt file = doesn't do that anymore, it creates the txt file, but doesn't append the data, any thoughts???

VB

<pre lang="xml"><%@ Page Language=VB Debug=true %>

<script runat=server Language=VB >
    'Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
    Dim intBtnClkCount As Integer = 0
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles writeButton.Click

        intBtnClkCount += 1


        ' writeButton.Visible = False
    End Sub
    Sub objWriter(ByVal s As Object, ByVal e As EventArgs)
        Dim FILE_NAME As String = "C:\Users\Fe\Desktop\xml\test.f"
        Dim DBConn As OleDbConnection
        Dim DBCommand As OleDbDataAdapter
        Dim DSPageData As New DataSet
        Dim I As Long
        DBConn = New OleDbConnection( _
            "PROVIDER=Microsoft.Jet.OLEDB.4.0;" _
            & "DATA SOURCE=" _
            & Server.MapPath("storage1.mdb;"))
        DBCommand = New OleDbDataAdapter _
            ("Select * from samplesource", DBConn)
        DBCommand.Fill(DSPageData, _
            "samplesource")
        For I = 0 To DSPageData.Tables("samplesource").Rows.Count - 1
            Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

            lblMessage.Text = lblMessage.Text _
                & "<BR>Processed Record: " _
                & DSPageData.Tables("samplesource"). _
                Rows(I).Item("s1")

Solution 1

You have create an object of the StreamWriter class.
However, you need to write to it using the Write() or WriteLine() method.

You are simply writing text to a label - lblMessage.Text.
