Vs2013 failed to create tracking tooltips with c++ RRS feed

  • Question

  • WIN32SDK program: When I use vs2013 to create tracking tooltips ( https://msdn.microsoft.com/en-us/library/windows/desktop/hh298405 (v = vs.85) .aspx ) at MSDN, When the uFlags member of TOOLINFO structure  contains a TTF_TRACK item, the tooltips is created successfully, but it cann't be displayed. Use spy ++ to observe the message of this tooltips window and find that the app always receive TTM_TRACKACTIVATE and TTM_SETTOOLINFO message,  all other messages are not received. But when I create application which has the same code as the previous application based on MFC dialogbox frame in vs2013  or in vc ++ 6.0, tracking tooltips can run properly, I think it may be a version of the problem, but do not know how to solve, Or there are some other problems , please help!
