我已經徹底地遵循http://msdn.microsoft.com/en-us/library/aa767914(VS.85).aspx以註冊自定義URL協議，我會爲了使用集成我寫的申請中描述的步驟在C＃中使用Pocket Internet Explorer。這個想法是點擊類似於xpto://something/?with=1¶meters=2的鏈接，並立即打開應用程序。嘗試，在Windows Mobile註冊一個URL模式（自定義協議）6.1
這是一直髮生在我身上：
如果我只註冊協議，它不會在所有的工作。 IE抱怨
Cannot open 'xpto://something/?with=1¶meters=2'. Either it is not signed with a trusted certificate or one of its components cannot be found.錯誤。如果我也註冊一個
.xpto文件類型，使用方法http://www.1-script.com/forums/IE-Windows-Mobile-MIME-Handler-What-s-the-solution-article7966--15.htm，我可以讓應用程序打開只有當URL與xpto://開始，以.xpto結束，像xpto://somehost/file?parameters=1.xpto。這是它實際工作的唯一時間。沒有任何錯誤。如果我僅使用上述方法註冊文件類型，則使用類似
http://somehost/test.xpto的URL可讓IE顯示其下載對話框，而無需直接打開文件。
我可以和2號一起去，但除了是地獄般的討厭之外，我真的很想知道這裏發生了什麼。這是我的第二天，我無法在互聯網上找到任何關於此的答案。我檢查了我的註冊表項數千次，發現沒有錯誤或拼寫錯誤。
下面是我的駕駛室安裝.inf，關於創建註冊表項。當使用註冊表編輯器探索移動設備時，我發現%InstallDir%設置得很好，引號也是如此。第一組註冊文件類型，第二組註冊URL協議。

我的應用程序在手機的內存中。我究竟做錯了什麼？
