Hi,
I'm trying to translate the following error message:
parser_e_ill_msg_param=03144_E_Message handlers can take only one call
by ref. parameter
% A method declared with the \var{message}-directive as message handler
% can take only one parameter which must be declared as call by reference
% Parameters are declared as call by reference using the
\var{var}-directive
And I can't seems to understand it's meaning. Can you please explain it
to me ?
Correct:
TTest = class
private
procedure CMTest(var Msg: TMessage); message CM_TEST;
end;
Incorrect
procedure CMTest(Msg: TMessage); message CM_TEST;
or
procedure CMTest(var Msg: TMessage; i: integer); message CM_TEST;
etc.
The signature of a message handler is fixed.
