Default problem getting out of infinite loop and incremtin

Hi all. I got this application that once go button clicked it takes single url value and goes trough some process as shown in pic and at the end writes the content of text4 to a text file. Now i want automate this process for range of range of URL i tried to do the following but i get into infinite loop and value of URL does not get incremented and only one url get executed succssefully!! I be happy if some one look at it and let me know how i can fix this problem.Thanks

layout of form without using loop for single url . which works perfectly:


' start from here
'Private Const sURL As String = "http://localhost/player/player.asp?id="
Dim CurrID As Integer

Private Function NextURL(Optional Reset As Boolean = False) As String
    If CurrID = 0 Or Reset Then CurrID = 16411
    If CurrID = 16420 Then Exit Function

 Const sURL As String = "http://localhost/player/player.asp?id="
        'NextURL = sURL & CuurID
        NextURL = sURL & CurrID

        MsgBox "URL:" & NextURL

        CurrID = CurrID + 1

        MsgBox "CurrID" & CurrID

        'Text2.Text = Inet1.OpenURL(CurrURL, icString)
             ' MsgBox "testing"
    'End If
End Function

' once i click the go button this function start with first url and should
keep chaing url by incrementing it untill it reaches end of the range

Private Sub Command3_Click()

Dim CurrURL As String
CurrURL = NextURL
'to reset
CurrURL = NextURL(True)

Text1.Text = CurrURL
MsgBox "CurrentUrl:" & CurrURL
MsgBox "nexturl:" & NextURL

    Select Case Index
    Case 0
        If Text1.Text <> "" Then
            Text2.Text = Inet1.OpenURL(CurrURL, icString)

        End If

    Case 1
    End Select
   'MsgBox "testing"

Command3_Click ' caling himself again
End Sub

Private Sub Command4_Click()
' It returns a string so just use it like:
'Text3.Text = GetLine2(Text2.Text, "mp3player.swf?playlist=", ".exe")
Text3.Text = "http://localhost/player/" & GetLine2(Text2.Text, "mp3player.swf?playlist=", ".exe")

End Sub

Private Function GetLine2(ByVal sText As String, ByVal sStart As String, ByVal sEnd As String) As String
    Dim lPos As Long, lEnd As String
    lPos = InStr(1, sText, sStart, vbTextCompare)
    If lPos Then
        lEnd = InStr(lPos, sText, sEnd)
        If lEnd Then
            GetLine2 = Mid$(sText, lPos + Len(sStart), lEnd - (lPos + Len(sStart))) & sEnd
            GetLine2 = Mid$(sText, lPos + Len(sStart))
        End If
    End If
End Function

Private Sub Command5_Click()
Select Case Index
    Case 0:
        If Text3.Text <> "" Then
            Text4.Text = Inet1.OpenURL(Text3.Text, icString)
        End If

    Case 1:
End Select

End Sub

' this funcion needs to write to a text file
Private Sub Command7_Click()
'Dim Parser As New clsXMLParser
 ' Dim Node As clsXMLNode
  'Dim Child As clsXMLNode
  Dim fn As Long
  'Dim i As Long

 'Dim path As String
  'Dim title As String

  fn = FreeFile
  Open "C:\albums.txt" For Append As #fn
  'Yes. Use Print #fn instead of Write #fn
    'Write #fn, Text4.Text
    Print #fn, Text4.Text
  Close #fn

  MsgBox " file written successfully to the file!"
' after this part i want the url get incremented and it getchecked in Command3_Click

End Sub[/VBCODE]
