Well, trying to copy MFC is fraught with danger and intrigue. MFC tends to do a lot of monkey business behind the scenes. For instance, quite often, instead of calling new, MFC will allocate memory for an object, then call the objects constructor manually. I guess it makes sense if you consider that MFC came from DOS originally, over 10 years ago. Anyways, how MFC does this is hidden in the constructor for CWinApp. In there, They do a few things, such as a module state variable = this (this being the CWinApp object) and doing some asserts that will assert if you try to create more than one instance. This isn't the best way to do this, however. The better way would be to make your MyFrameWorkApp a singleton object, which makes it impossible to create more than one instance. If you don't know what a singleton is, I suggest doing some web searches on it, or buying the most excellent book "Design Patterns". The reason you can't single-step into this is that the CWinApp's constructor get's called *BEFORE* WinMain. You have to put a breakpoint in CWinApp's constructor before you execute the app. -- Where are we going? And why am I in this handbasket?
