Mark,

I thought you might find this chunk of code handy. It allows you access to
the PostData when an HTTP Post is made. I got the code from Microsoft a few
months ago and it's come in pretty handy. I just added it to your
wb_BeforeNavigate2 event.

'*
'* Start of code
'*
Private Sub wb_BeforeNavigate2(ByVal pDisp As Object, url As Variant, Flags
As Variant, TargetFrameName As Variant, PostData As Variant, Headers As
Variant, Cancel As Boolean)
    If mnuEditLink.Checked Then
        If mnuBlockServers.Checked Then
            For i = 0 To UBound(blockServers)
                If LCase(blockServers(i)) Like LCase(url) Then Cancel =
True: Exit Sub
            Next
        End If
        'this wont modify link browser requests though :(
        url = frmAnalyze.AnlyzeUrlAndWait(url) & " "
        If url = -1 Then Cancel = True
    End If

    '*
    '* Code added by Dennis Hurst (dhurstspidynamics.com)
    '*

    'url will contain the URL with parameters
    'PostData has the PostData in a strange format
    'the following will convert it to a string that
    'contains the raw post data

    Dim lLen As Long
    Dim strPostData As String

    lLen = LenB(PostData) ' Use LenB to get the byte count

    If lLen > 0 Then ' If it's a post form, lLen will be > 0
      For lCount = 1 To lLen - 1
          strPostData = strPostData & Chr(AscB(MidB(PostData, lCount, 1))) '
Use MidB to get 1 byte at a time
      Next
      Debug.Print strPostData
    End If

End Sub

'*
'* End of code
'*

God Bless & Have a great day,

Dennis Hurst

As you already capture the form, you could check for cross site scripting by
automatically sending in a payload to a form field target. How cool woukd
that be....oh yeah. And you could have a drop down maybe of the known
payload variants like <script> <img src> etc

That would be the best .....
