c++ use of winmain()

hop of those help? main() is as arbitrary an entry point as WinMain() is. The standard only requires a function named main for consistency. The entry point (whether it's main or WinMain) is actually called by a hidden function that is the real entry point. On some platforms that "real" entry point is called something like _start. It's that function that does all of the initial work like initializing globals, setting up the environment, etc., and then it calls main(). On Windows, that start function happens to call WinMain() if available.

How to add a wrapper to the MFC WinMain?

this one helps. It is possible, just check the command line parameters in order to change the behavior. Check http://msdn.microsoft.com/en-us/library/ms687414(VS.85).aspx
In case you will want to make it work as console remember that it is not possible to make an application that is running as both console and GUI on Windows. Still there is not limitation for services, a service application can be a GUI one or a command line one.

I believe WinMain is NOT C or C++ standart, but is only added by Microsoft to determine when to load different CRT startup code, am I right?

WinMain vs. main (C++)

I hope this helps you . Talking about the Microsoft toolchain, conventionally, Win32 graphical applications have always started with WinMain, while main is used for console applications.
The difference between the two kinds of applications actually boils down (mostly) to a single setting in the executable, and is not in capability - a GUI application can create a console, and a console application can create a window - but in the behavior of the loader: for an exe marked as GUI the loader won't allocate any console, while a console exe will attach to the parent's console or create a new one if there isn't one.

WinMain exported from a DLL

I wish did fix the issue. This is not possible as-is, the linker can only set the entrypoint for an EXE to a function that's inside the EXE. Rename the wWinMain() in the DLL to something else. Write a wWinMain() in a source code file that gets linked into your EXE, simply call the DLL's exported function.
