Hi im new in c++ but im very interested. i have visual studio 2008 and 2012... i have been a VB programer for a few years now, so now i want to try my hand in something new...
OK now c++... i learned how to make a console APP in some study documents that i hav but i can't find C++ Windows Forms application study texts or tutorials anywhere,,,i wonder why, so now i am self studying...
i can create and debug a c++ windows form in VS 2008 successfully.
BUT.in VS 2012 i CAN'T.... i go->
new Progect->Visual C++ ->CLR->Empty project(chosen from:Class Library,console app, empty project)
i say ADD Item->UI->Windows form....
COOL! now its added... but when i test run it, it gives me a LINK error
"Error 1 error LNK1561: entry point must be defined"
i searched online, and they say i must go to : Project properties->Configuration Properties->Linker->system:
and then set the Subsystem option to "Windows(/SUBSYSTEM:WINDOWS)"
but that still doesnt help... please i need profesaional help.

There are at least two active C++ forums: C++ Standards, Extensions, and Interop and Visual C++.

If you have c/C++ questions, you will probably have better luck in one of the C++ forums.
This particular error means you did not define a function named main. Every C++ program receives control in that function.

i tried to find c++ forum here but cant find so im trying... i know the main() function is needed... but i cant put it in. where to put it in,,,,in C++ 2008 and 2012 when u make windows forms application and u view the automatic code required,,,then the main() isnt there... even in the 2008 that run successfully off the block.... 2012 just doesnt want to.... with or without a main....
see here is the code that run successfully in 2008 and its witout a main() and it was generated automatically... i havn't touched it....just created a project and ran it...and it works... but 2012 loks EXACTLY the same...but give the link error
