How to implement this?

[sci]

How to encapsulate a main() into a class as a member function? Just like in
Java which hides main() function, or like MFC which hides WinMain()?

Something like:

StartClass
{
public:
static int main(){...}
};

You cannot. So you have to go through the ordeal of writing:

int main() {
return someclass::main ();
}

or the worse:

int main( int argc, char *argv[]) {
AppClass appObject;
return appObject.main( argc, argv);
}

or the unbearable one (which you will never need to touch again):

#include "someframework. hpp"

int main( int argc, char *argv[]) {
AppClass *pAppObject = AppFactory::Cre ate();
return pAppObject->main(argc, argv);
}

Well, MFC usually comes with its source code. "Use the Source, Luke!"

I am not sure what you need it for. If you want to create some kind
of "light-weight" MFC clone, look at how MFC is made, and follow suit.

Note that when using MFC, there should be no 'main' function in your
program. The 'main' will be supplied from the library. There is no
"encapsulat ion" per se. The trick is that the library-supplied 'main'
finds out what the current "CWinApp" object is and calls its members
in a certain order with certain arguments.

More on MFC in microsoft.publi c.vc.mfc.

You cannot encapsulate main into a class as a member function.
This is one of the reasons C++ is not termed as a __pure__ OO Programing
Language.

afaik,
MFC does not encapsulate main into a class as a member function. Instead
main() is added by the library.

Please read this before you post again:

http://www.parashift.com/c++-faq-lite/how-to-post.html#faq-5.4

And please reply to the post you are answering to. You have answered to the
OP replying to my post, with which you have implied that I stated that main
can be a member function etc. Furthermore the OP might not even read your
post, since you have replied to mine.
