searching data in an access database

Hey everyone, I know how to search for one specific number from a single line in an access database using a query, but now I have to search through a whole database and display each instance. Ex) I search the number "1" in column "1" of the database and it has "2" instances. So now I have to take the corresponding data in the rows next to it in order to display them in the label.

search: "1", both results are ID = "1"

results:
dates amount
10/13/2009 $43.00
12/25/2009 $86.00

I know how to put the results for "1" line of a database into the .item field, but im confused on how to search multiple lines of a database and store multiple items. Heres what I have so far...

Code:

---

Private Sub btnShowPay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShowPay.Click
        Dim targetid As String
        Dim dummy As Integer
        Dim selectstring As String
        Dim dates As String
        Dim amount As String
        Dim total As String

        If Not Integer.TryParse(txtID.Text.Trim, dummy) Then
            MessageBox.Show("member id must be integer")
            txtID.Focus()
            txtID.SelectAll()
            Exit Sub
        End If
        targetid = txtID.Text.Trim

        'create select statement
        selectstring = "select * from payments where member_id = " & targetid

        'find total amount of rows in database
        total = "select * from payments"

        'create adapter
        memberadapter = New OleDb.OleDbDataAdapter(selectstring, connectionstring)

        'create and fill the member data table
        membertable = New DataTable
        memberadapter.Fill(membertable) 'fill the data table

        'check to see if a member was found or not
        If membertable.Rows.Count = 0 Then
            lblDispPay.Text = "id not found"
            Exit Sub
        End If

        lblDispPay.Text = "Dates            Amount"

        ' extract data
        For x = 0 To CInt(total) Step 1
            dates = CStr(membertable.Rows(x).Item(2))
            amount = CStr(membertable.Rows(x).Item(3))
            lblDispPay.Text &= dates & "  " & amount
        Next x

    End Sub

So i figured out the loop, but I dont know how to set the end of the loop. Its keeps giving me an error message (index out of range). How do i change it, so it stops when it finishes going through all the numbers? Thanks...

Code:

---

' extract data
        For x = 0 To ??? Step 1
            dates = CStr(membertable.Rows(x).Item(2))
            amount = CStr(membertable.Rows(x).Item(3))
            lblDispPay.Text &= dates & "  " & amount & vbCrLf
        Next x

??? should be the total count of the record minus 1 (since thes tart of your array is 0)

Dim TotalCount as integer = membertable.Rows.Count - 1

For x = 0 to TotalCount

Next
