In delphi, I have an edit box and I need to test each character to make sure its not one of the following: \ / : * ? " < > | and if it is, it needs to be removed. How can I find out if one of the symobls are entered. I know I can test them on key presses but I dont know what to compare them to.

do you want to filter then, so the user can't insert them in the first place, or do you want to remove them afterwards?

Try onKeyPress event,  something like this

  if  Key in ['\', '/', ':', '*', '?', '"', '<', '>', '|']  then Key := #0;

that would be

  if  (Key in ['\', '/', ':', '*', '?', '"', '<', '>', '|'])  then Key := #0;

Either would be acceptable, would be better not allowing them to be entered in the first place.
