anyway to bold 1 line in a listbox?

[andrew]

the project im currently working on searches an external text file and displays the search results from that text file in this list box.
my question is, is it possible to have just 1 line of a list box be bold text or highlight even while leaving the others lines at normal font?

im looking to make a common word or the whole line that this word is in stand out from the rest when its found.

is this possible or would anyone have a clever way to accomplish this?

I don't think there is any way to achieve that with a listbox.  I'd be inclined to use an HTML control.
