-On Windows, container controls are just regular controls that notify their parent when the user wants to do things; changing the contents of a switching container (such as a tab control) must be done manually.
-
-We'll create a dummy window using the container window class for each tab page. This makes showing and hiding tabs a matter of showing and hiding one control.
