    原先的Task Manager应用程序显示顶层窗口的列表。为了显示该列表，窗口           
必须可见、包含一个标题以及不能被其他窗口拥有。调用CWnd:: GetWindow可以           
检索顶层窗口的列表，调用IsWindowVisible、GetWindowTextLength以及GetOwner         
可以确定窗口是否应该在列表中。下例将把TaskManager窗口的标题填充到列表中。        
                                                                                 
void GetTadkList (CListBox&list)                                                 
{                                                                                
     CString strCaption;        //Caption of window.                             
                                                                                 
     list.ResetContent ();       //Clear list box.                               
                                                                                 
     //Get first Window in window list.                                          
     ASSERT_VALID (AfxGetMainWnd ());                                            
     CWnd* pWnd=AfxGetMainWnd () ->GetWindow (GW_HWNDFIRST);                     
                                                                                 
     //Walk window list.                                                         
     while (pWnd)                                                                
     {                                                                           
         // I window visible, has a caption, and does not have an owner?         
         if (pWnd ->IsWindowVisible () &&                                        
            pWnd ->GetWindowTextLength () &&! pWnd ->GetOwner ())                
         {                                                                       
            //Add caption o window to list box.                                  
            pWnd ->GetWindowText  (strCaption);                                  
            list.AddString (strCaption);                                         
         }                                                                       
         //Get next window in window list.                                       
         pWnd=pWnd->GetWindow (GW_HWNDNEXT);                                     
     }                                                                           
}
