Description:
I looked through your code and found that it contains some methods which would be very handy for me. Unfortunately, they are declared as protected. As far as I know I cannot access them from my code or is there a trick?
Answer:
In order to get the value of a protected property (or call a method) you need to create a new class derived from the object's class and then typecast your object to the created class - this is commonly referred to as "cracking a class". i.e., you may use the following code:
Delphitype
TmyType = class
protected
function DoSomething(A: Integer): Integer;
property ResultOfMethodAbove: Integer;
end;
var
A: TmyType;
type
TmyTypeAccess = class(TmyType);
...
var
I: Integer;
...
I : = TmyTypeAccess(A).DoSomething;
OR
I : = TmyTypeAccess(A).ResultOfMethodAbove;
Is there some article like this focused on C++?
Thanks
