How do I make an event handler for a button in the MessageBox?

[AceDawg45]

I know how to make buttons with event handlers, and I somewhat know how to do this. What I do is this:

MessageBox(hwnd, "Do you really want to leave?", "Leaving?", MB_YESNO);

if("YES")
    PostQuitMessage(0);
else if("NO")
    //whatever I will put here... 

So, anyway, I put that but if I click No, it will do what I prompted 'yes' to do. How do I make 'no' to do a separate action?

int msg = MessageBox(NULL, L"Do you really want to leave?", L"Leaving?", MB_YESNO);

switch (msg)
{
case IDYES:
	MessageBox(NULL, L"Yes", NULL, MB_OK);
	break;

case IDNO:
	MessageBox(NULL, L"No", NULL, MB_OK);
	break;
}

MessageBox returns and int so you can get a value depending on the button.
