调用ie的收藏夹（系统需要ie4以上版本）
internet explorer 库--shdocvw.dll包含了许多可以操纵ie收藏夹的api。其中的两个api是调用ie的“添加到收藏夹”和“整理收藏夹”对话框。下面的示例程序就是如何使用这两个对话框
。
“添加到收藏夹”的dialog很像windows的通用对话框中的saveas dialog，它自身没有任何机能（不能创建或保存一个文件）。然而他却提供了一种机制，当用户创建并保存一个
internet的快捷方式时，可以让开发人员能够得到需要的“收藏夹”中的信息。因为它会接受到一个pidl参数，当调用shgetspecialfolderlocation函数时指定了csidl_favorites，
就会返回用户“收藏夹”的pidl描述。再把它用作api中的一个成员，我们想要的“添加到收藏夹”对话框就会出现了。
“整理收藏夹”对话框可以提供我们创建创建文件夹、重命名文件夹和删除文件夹等功能。
