CWinAppEx::InitTooltipManager
Visual Studio 2012
Initializes the CTooltipManager object.
BOOL InitTooltipManager();
If you call CWinAppEx::GetTooltipManager, the default implementation of that method calls InitTooltipManager.
If your application already has a tooltip manager and you call InitTooltipManager, your application will have an ASSERT failure. Therefore, you should not call InitTooltipManager if you create a CTooltipManager object directly. If you are not using a custom CTooltipManager, you should use GetTooltipManager to create a CTooltipManager object.
