Hi Guys,

I have a custom function that finds a hyperlink/s in a cell.
It wasn't written by me but sourced on the web somewhere, unknown
origin.

Here is the code...

Function TextLink(cellT As Range, Optional defVal As Variant)

If (cellT.Range("A1").Hyperlinks.Count < 1) Then
TextLink = defVal
Else
TextLink = cellT.Range("A1").Hyperlinks(1).Address
End If
End Function


This works fine, however what it does do is seems to get called by
totally unrelated code in other worksheets in the same workbook. I
don't know why, and I would like to know why.

I have rewrote the code with this...

Function TextLink(cellT As Range, Optional defVal As Variant)

If (cellT.Offset(0, 0).Hyperlinks.Count < 1) Then
TextLink = defVal
Else
TextLink = cellT.Offset(0, 0).Hyperlinks(1).Address
End If
End Function

This also works but doesn't (after testing) seem to get called by other
seperate code in other worksheets in the same workbook.

Now in the first code the cellT range is A2 and the function is sat in
B2. I'm extracting the first 55 characters of the hyperlink. I'm using
this..

=LEFT(TextLink(A2,""),55)

Works ok. Returns an empty string if there's no hyperlink.

The problem as I see it is the .Range("A1") part of the original
function. Is it open to be called by any sheet at any time if A1 is
selected?

It isn't a problem while the code runs at normal speed, but when I'm
stepping through to debug I'm getting this function being called and
insisting on looping through itself possibly hundreds of times before I
get sick and have to end the debug.

I'm quite happy at the rate I'm learning VBA, but I'm getting stuck on
functions and their behaviour more and more often.

Can anyone shed any light on this please?

Thanks guys,

Ron
