m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);//自己创建的工具栏
DockPane(&m_wndToolBar);

DockControlBar(&m_wndToolBar)里面的m_wndToolBar的控件类型是不是CMFC开头的。CMFC是VS 2008以后新加入的控件库，你的教材可能是更早版本的了。用上面的方法试下

vs2010中不需要这一步，直接
m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY);//自己创建的工具栏
DockPane(&m_wndToolBar);

你查一下，看CMFCToolBar 和 CControlBar 类型匹配不？类型匹配才能相互转化

VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
