<p>扁平钮和把手</p>

<p>在过去的</font><font FACE="Arial">18</font><font FACE="System,黑体" LANG="ZH-CN">个月中我常常被问及该如何获得象</font><font
FACE="Arial">Internet Explorer</font><font FACE="System,黑体" LANG="ZH-CN">和</font><font
FACE="Arial">Visual Studio</font><font FACE="System,黑体" LANG="ZH-CN">中的工具条一样不使用浮雕按钮而是用扁平钮并且带有便于移动和定位的把手那样酷的界面。这些特色并不被</font><font
FACE="Arial">MFC</font><font FACE="System,黑体" LANG="ZH-CN">所支持，因此最简单获取的方法就是购买一个扩展库。而对于</font><font
FACE="Arial">Visual C++ 6.0</font><font FACE="System,黑体" LANG="ZH-CN">来说却无须多此一举，因为它使得</font><font
FACE="Arial">CToolBar</font><font FACE="System,黑体" LANG="ZH-CN">类实现了对扁平钮、把手和其它新的视觉效果的支持。</p>

<p>在预览版中，</font><font FACE="Arial">AppWizard</font><font FACE="System,黑体"
LANG="ZH-CN">并不会自动包括这些新特色，但它们却很容易被加入。表</font><font
