HELP BPW7: how to write to listbox in a different colors

Can someone help me ?
 I want to write lines into a listbox but in a different colors - I
need to color part of a line in a different color (e.g. I search a
substring in a file and I want to fill listbox with lines which  have
substring  but I want that part of a line with substring to be written
in a different color !) How it can be done ?
