Auto_ptr, as the earliest intelligent pointer, can realize the management of the heap area object by RAII, but it is designed simply to use C + + for the automatic destruction of the stack object to manage the heap area object,Unlike shared_ptr,

When you use the TabControl control, you want to hide one of these tabs (that is, TabPage). The TabPage class clearly provides a hide method, and it is strange to use the code without any effect. Helpless, had to consider another way.Method One:The
