CTreeView是VC＋＋裡面的試圖類，在文檔/試圖結構應用程序裡面，簡單的實現TreeView的樣式，就象WINDOWS裡面的資源管理器那樣的樣式（左邊包含目錄樹）。
CTreeCtrl是一個控件類，它象其他普通控件那樣可以在窗口上建立並操作，就象WINDOWS裡面的資源管理器的左邊的目錄樹那個控件。
MFC provides two classes that encapsulate tree controls:CTreeCtrl andCTreeView. Each class is useful in different situations.
Use CTreeCtrl when you need a plain child window control;
for instance, in a dialog box. You'd especially want to use CTreeCtrl if there will be other child controls in the window, as in a typical dialog box.
Use CTreeView when you want the tree control to act like a view window indo
cument/view architecture as well as a tree control. A CTreeView will occupy the entire client area of a frame window or splitter window. It will be automatically resized when its parent window is resized, and it can process command messages from menus, accelerator keys, and toolbars. Since a tree control contains the data necessary to display the tree, the correspondingdo
cument objectdo
es not have to be complicated you could even useCDocument as thedo
cument type in yourdo
cument template.
