"R.Wieser" <address@not.available> wrote | The whole process using the 25 MB string still takes several seconds to | complete though. Oh well. | Did you try a UCase or LCase first and then ReadAll? I don't see the point of reading by line unless you expect to be quitting near the beginning. I don't know how case works. It wouldn't be difficult to just search for "65 or 97" (A or a). But either way it's a more complex search. I imagine it might also depend on the length of the search string and how many similarities there are. If you have 25 MB of "orange is the new black" and one instance of "orange is the new green" near the end, I would expect all those near matches to bog things down. But I've never actually tested it.
