Find string in Delphi listbox

Posted by P14347 Pete Lavigne on April 26, 2004 at 17:38:56:

I have a listbox that I fill with lines from a textfile with the LoadFromFile('c:\data\data.txt') function. That works fine. But now I want to find a string of this listbox. The string is typed in an edit-component. Can you help me with a code example?
