Hello!

I wonder if somebody could help me!

I have a class TProcessDescription -
which inhterits from TObject.

I have declared a Pointertype
type PProcess = ^TProcessDescription;

In my program I try to create this object dynamically
and call its create method

procedure myForm.myProc;
var
   proc_desc : PProcess;
begin
  new(proc_desc);        // OK
  proc_desc^.create;   // Wooooouups
  // The create method crashes when calling
  // inherited create;
end;

Why... WhYY WHYYYYY!

Found it out myself!

procedure myForm.myProc;
var
   proc_desc : PProcess;
begin
  new(proc_desc);
  // proc_desc^.create;   // ERROR
  proc_desc^ := TProcessDescription.create; // OK

end;

Hi Terje,

  I dont think the New procedure could be used to actually create an
object, with its virtual table and methods. It basically just reserves
a block of memory and returns a pointer to it.
 Usually you would call the constructor of an object this way :
proc_desc := TProcessDescription.Create;

Hope this helps.
If not then i am the one who is gonna learn something here ;-)
