为PowerPoint2010文档创建自定义任务窗格

          目前，参与PowerPoint Add-in项目开发。测试组发现打开两份PowerPoint2010文档，第二份文档里没有自定义任务窗格，而PowerPoint2007不会有该问题。查阅微软的MSDN相关文档，原来微软对PowerPoint2010文档框架作了改变，不再是采用PowerPoint 2007 会为所有文档（即工作簿和演示文稿）创建一个文档框架窗口,而是为每份文档都创建一个文档框架窗口。为了解决这个问题，我们需要在PowerPoint2010创建新文档或打开现有文档时为该文档创建自定义任务窗格。考虑到后续程序的需要，采用HashTable存储自定义任务窗格实例和索引。
