Create A Fixed Text File From SQL DB Table

Hello programmers. I am trying to retreive data from an SQL db table using VB in a .NET aspx page (visual studio 2005), confirm that there are records (i.e. record count, etc.) then print the data into a fixed text file somewhere on my network. I did this in Visual Basic 6 using selects, padstrings, freefile, recordcount properties, etc. hitting an Access db table. However I am not able to repeat this in .aspx page. Below is the script I used to output the text file from the MSAccess table. Thanks for the support.

Code:

---

Public Sub tbl2txt()

Dim wrk As dao.Workspace
Dim db As dao.Database
Dim cnn As dao.Connection
Dim rs As dao.Recordset
Dim strTable As String
Dim strFileName As String
Dim intFileNum As Integer

On Error GoTo err_Tbl2Txt

strTable = "QBtmLine"
' Create Microsoft Jet Workspace object.
Set wrk = CreateWorkspace("", "admin", "", dbUseJet)

Set db = wrk.OpenDatabase("U:\DEVHELP_DBs\Ilfornaio\Access2000_a\botline_2k.mdb")

Set rs = db.OpenRecordset("Select * From " & strTable)

With rs
'check to see that records were returned
If rs.RecordCount < 1 Then
MsgBox "No records found for Bottom Line Check File"
Me.Refresh
End If
intFileNum = FreeFile

strFileName = "H:\Acct\BT_2kTesting\blinetxtapp_2k\Blintes1.txt"

Open strFileName For Output As intFileNum

.MoveFirst
Do While Not .EOF

'File is fixed
Print #intFileNum, Format(!paydate, "mm/dd/yy") _
& PadString(Format(!checkamt, "###,#00.00"), " ", 13, False) _
& PadString(!Name, " ", 80, True) & PadString(!add1, " ", 35, True) _
& PadString(!add2, " ", 35, True) & PadString(!add3, " ", 35, True) _
& PadString(!add4, " ", 2, True) & PadString(!postcode, " ", 10, True) _
& (Format(!docdate, "mm/dd/yy") _
& PadString(Format(!invoiceamt, "###,#00.00"), " ", 13, False) _
& PadString(!vendor, " ", 72, False) & PadString(!invno, " ", 34, False) _
& PadString(!checkno, " ", 24, False) & PadString(!sname, " ", 25, True) _
& PadString(!Group, " ", 15, True) & PadString(!groupname, " ", 35, True))

.MoveNext
Loop

End With

Close intFileNum
Set rs = Nothing
db.Close
Set wrk = Nothing
Exit Sub

err_Tbl2Txt:
MsgBox "Error" & Err.Description & "occurred in Tbl2Txt, Correct then Rerun."

End Sub

Do you know how to run an SQL query against a database using VB.NET and get a recordset in return?

Below is my new working vb.net script which creates a text file if there is data in the table. However it is only putting out manual text. I need to loop through the table assign the fields (I guess) to variables and then somehow get the variable values into something similar to the writeline in a fixed format. I am getting the count of the records, but I'm kind of lost from there. Any help is appreciated.
