when is the destructor called ?

[stephenprogrammer07]

Quick question

When is a destructor called ?

      ThreadManager::~ThreadManager()
      {
            CloseHandle(m_hThread);  
      };

Let's say this was in my code ?
Is the destructor called if this object goes out of scope ?

Example

void foo()
{
ThreadManager t ;


};

Is the destructor called when the scope has ended ?
Is there a way to call the destructor explicitly ?

Is it just as simple as delete t;

Thanks
