Right: A user types a URL into any cell in a particular column that you'll
specify, and you want to get Excel automatically to turn the URL into a
clickable link. (What the link displays is a mere detail; once you know how
to create a link, you can make the displayed text ("WWW") and the actual URL
whatever you say they should be.) Here's what you need to know:
1) How to create a link in Excel. I've never done that before, but the Help
file seems clear enough. I expect you already know this part; if not, just
go to Help and enter "create hyperlink" to see the directions on that.
2) How to write a VBA program in general. I've been assuming you already
have this part under your belt; some people come here not knowing even that
(you gotta start somewhere, after all), but most folks here already know this
part. If you don't, this little task of yours actually isn't too bad a place
to start -- but we'll have to go over some fundamentals first or the actual
doing of it won't make any sense to you.
3) How to get a VBA program to run whenever a user changes a cell. For that
it seems to me you need a Worksheet_Change subroutine, which is what I was
referring to below, and my first guess was that this is the part you don't
already know how to do -- but maybe not, based on your reaction.
4) How to code the VBA statements that will create the link that you already
know how to create manually. I haven't tried that yet, but I expect once you
know the first three things, this would fall into place pretty naturally. So
I don't think this is what you're asking.
If you know all of the above four things, it seems to me, then you know how
to do what you're trying to do. Therefore I figure your question is how to
do one or more of the above. Which?
