我想添加自定義屬性爲我的應用程序文件類型，就像.DOCX在Vista和視窗7中顯示作者在詳細信息窗格性能Microsoft Word文件tyep財產等試圖爲我的應用程序做同樣的事情，但還沒有線索。在.net2.0中工作。我不知道我在做什麼錯，使物業處理程序爲我的應用程序自定義屬性添加到文件格式

我是否需要instatiate屬性處理器類。如果是，我應該怎麼做，任何想法的人，我一直在這裏呆了3天。 當我註冊這個DLL屬性處理程序獲取註冊但沒有自定義屬性出現在.test文件。
P.S：我從msdn論壇取得這段代碼，並在我的應用程序中執行，顯然沒有成功。 – PUG 2010-10-19 10:19:20
嗯;這是一個非常具體的情況;你可以參考MSDN源碼嗎？ – 2010-10-19 10:31:09
msdn.microsoft.com/en-us/library/bb776861(VS.85).aspx，這篇文章我使用，我真的不知道很多關於這一點，我已經預覽處理程序，我的文件，但從來沒有財產處理 – PUG 2010-10-19 11:08:11
