 |
|
I have been away from OOP too long. The following generates an access
violation at the place indicated by <-- below. If I remove the
"virtual" qualifier, it works, but then I cannot write override
versions of the method (which I need).
Wonder if a compiler directive may be the problem?
tks,
Jack
type
tTestClass = class
procedure GetReady;
procedure DoAction; virtual;
end;
var TestClass : tTestClass;
implementation
procedure tTestClass.GetReady;
begin
ShowMessage( 'Getting Ready...' );
DoAction // <-- Access violation here
end;
procedure tTestClass.DoAction;
begin
ShowMessage( 'Doing the action...' );
end; |

Hoi Jack
Your question is more fitting for the newsgroup
b.p.d.language.delphi.general, try to repost the question there, and do
the repost to the Borland news server to make everybody see your message.
