Delphi "is not"-Syntax does not work
Question by Guest | 2013-10-31 at 20:07
I want to do the following with Delphi (negation of is):
if Sender is not TListView then ...
However, this solution is not working. What am I doing wrong? I always get the following error message:
Error: Illegal Expression
I do not want to write something like this:
if Sender is TListView then begin end else ...
But I do not have any other idea.

In Lazarus and Delphi there is no "is not".
Instead, you should use "if not":
That should do it. Writing the "not" directly behind the "if" is only possible in spoken language.
