Not that it applies too much to this example, but this is why I like C# and the GC. Don't really have to worry about freeing objects. Only thing you need to be concerned with is closing data connections and files.
Also, try catch finally is a better mechanism than try try except finally IMHO. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Conor Boyd Sent: Friday, 21 July 2006 2:53 p.m. To: NZ Borland Developers Group - Delphi List Subject: RE: [DUG] Related try..finally question But all your object creation shouldn't really be inside the try's for a start. When you call a constructor, and there's an exception inside the constructor, you're guaranteed that Delphi will tidy up the partially created instance. It gets a bit verbose, but IMHO the correct form is as follows: Something := TSomething.Create(nil); Try X := TX.Create(blah); //for some reason crashes here Try Y := TY.Create(); Try //Do Something Finally FreeAndNil(y); //will throw exception (?) because was never created End; Finally FreeAndNil(X); End; finally FreeAndNil(Something); End; Don't get me wrong, I don't often go too far down this route, preferring instead to refactor into smaller methods for a start. Dennis' is an interesting suggestion, tho'. I will look into that. Cheers, C. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Sugrue That's an interesting one. I guess you're talking about something like this? Try Something := TSomething.Create(nil); X := TX.Create(blah); //for some reason crashes here Y := TY.Create(); Finally FreeAndNil(Something); FreeAndNil(X); FreeAndNil(y); //will throw exception (?) because was never created End; If so then you could just If (something <> nil) then FreeAndNil(something); ??
