[Quiz] What will happen if SendMessage to self?

[myron]

This is an interesting thing (what i never thought of yet...) and I wonder how you people think it will happen.

We normally won't sendmessage to ourself, but what if we do that?

Here are the sample example:

LRESULT CDlgExeDlg::DefWindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
	// TODO: Add your specialized code here and/or call the base class
	switch (message)
	{
	case WM_MYTEST:
		{
			if (! SendMessage(WM_MYTEST)) {
				ASSERT(0);
			};
			
			int i = 0;

		}
.....

Because SendMessage is a synchronous function, so THEORETICALLY it will casue an infinite loop!

But is this true?

How do you people think?
