not sure, this is not my strength. I would write a module like this:
Function CHL(S As String) As Boolean
Dim i As Integer 'location of string searched, = 0 if not found
'---search for prerequsites: space or dot---
If InStr(1, S, " ", vbTextCompare) Then GoTo xit ' search for space
If InStr(1, S, ".", vbTextCompare) > 1 Then
'-----search for any of the following, add/delete lines as and required
i = i + InStr(1, S, "www", vbTextCompare)
i = i + InStr(1, S, "http://", vbTextCompare)
i = i + InStr(1, S, "com", vbTextCompare)
i = i + InStr(1, S, "net", vbTextCompare)
i = i + InStr(1, S, "org", vbTextCompare)
'if any of the following were found then it is a hyperlink
If i > 0 Then CHL = True
End If
xit:
Exit Function
err:
CHL = False
Resume xit
End Function
(just copy and paste this text into a new module)
you can then use the following expression for the controlsource of a field
in a form (just an example):
="The value for field X " iif(CHL([X])=true, "contains a hyperlink", "does
not contain a hyperlink")
Let me know if this does not make sense!

thanks for your response.
I don't see how to use the . as a placeholder in the instr command in
access 2002.
I am using regular expression module and almost have this working but not
quite.
Can you tell me how to do this with the . as a place holder?
Thanks

news:Fx*******************@news.xtra.co.nz... 1. i think access, in general is not case sensitive (unless you do a
binary search)
2. it is http:// not http:\\
3. i would use the dots as an identifier together with the instr
(instring function, see help) - you need to have at least one dot and no spaces to
have a valid IP address (e.g. bmx.com)
4. try to change your input format so that all ip addresses are entered
identical or update data that has been imported to http://...... as you
say, not all of them start with www.
