How to randomly select links in e-tester and how to get VU# in e-load

Question

1. How to randomly select one from links in a webpage in e-tester?
For example: there is a root-page. On it, there are about 2000 links to its subpages. They all have the following pattern:
<pre>
multiline<TD width="50%"><NOBR>
<img src="/images/tfold.gif" border="0" alt="GXC_.+?" align="texttop">
{a href="(.+?)"}<font class="titleorimageid1siteid0">GXC_.+?</font>{a} </NOBR>
</TD>
</pre>
So how can randomly select one link and then navigate to it?
2.how to get VU# in e-load?
For example: we launch 4000 VU to load-stress our server. But we want to use different user names to login for different VU#. such as VU#1's username is ADF1, VU#2's username is ADF2, VU#100's username is ADF100 and so on. How can we implement the feature?
Thanks a lot.

Answer 1

Thanks a lot for VU#. Also i got an idea about how to randomly select a link:
Private Sub RSWVBAPage_afterPlay()
Dim objReg As New RegExp
Dim objMatchCol As MatchCollection
Dim objMatch As Match
Dim objSubMatch As SubMatches
Dim doc As String
Dim str As String
Dim rNumb As Integer
RSWApp.GetHtml doc
With objReg
.Global = True
.IgnoreCase = True
'the kind of urls have the following special pattern
.Pattern = "pageid=34,([\d]{5})"
End With
Set objMatchCol = objReg.execute(doc)
Randomize
rNumb = objMatchCol.Count * Rnd
If objMatchCol.Count >= 1 Then
If rNumb = objMatchCol.Count Then
rNumb = objMatchCol.Count - 1
End If
End If
Set objMatch = objMatchCol.Item(rNumb)
Set objSubMatch = objMatch.SubMatches
str = objSubMatch.Item(0)
Call RSWApp.setCustomVariable("var_url", str)
RSWApp.WriteToLog str
Set objMatchCol = Nothing
Set objMatch = Nothing
End Sub
