Hi,

I would like to color 1 line over 2 in my listview.
till now i've just found how to color font of its items, but not row by
itself.

is it possible to color rows of a Listview component ?
if yes, how ?
thx,

Maileen

You can't format the individual items in the list.

If you want to colour all of the listitems, do a search for: Const
LVM_SETTEXTBKCOLOR

I dont know of a way to colour individual rows

Hi Rob,

Hooking the WinProc event handler... Now that's impressive.

... and *very* dangerous in an interpreted environment! Save regularly!

I think it looks impressive too, but for me crashes every time! Despite
fully heeding all safety warnings. VBE closed (no breaks), running from
Alt-F8, xl2k/w98se.

Peter T

It worked for me just fine - XL2003

Some of the line wrapping on that post screwed me up.
There was one that I missed were the line contained the word Message. It was
accepted without error by VBA, but was in fact a comment from the previous
line.

Hi Rob,

I'm very pleased you made me have another look. I thought I had carefully
"un line wrapped". I caught the line ending in "Message" which as you say
did not glow red. But there was another one I missed - lParam at the end of
the commented line starting "Copy our copy". After removing the stray
"lParam" all works fine.

Michel - please accept my apologies for casting aspersions on your amazing
code!!

I hope you will not mind if I take the liberty of reposting your code,
exactly as original but (hopefully) without any line wrapping.

Regards,
Peter T
