在與ActiveSync同步時讀取PDA目錄的內容

Question

我有一個項目，我需要複製PDA中找到的文件（在我的情況下，如果這有什麼區別，那是一個MC3000）。我安裝了ActiveSync，它爲我創建syncronisation文件夾就好了。但是，我希望能夠閱讀PDA的內容不僅在其MyDocument文件夾中，所以我不能使用它（加上它必須使用相同型號的20多個可能的PDA，從而製作20多個目錄）

有沒有辦法做一些IO內的PDA，而它是停靠和同步的ActiveSync是。

我可以在資源管理器中看到'移動設備'。

感謝

使用RAPI。這是一個codeplex項目，爲Rapi.dll和ActiveSync提供託管包裝類。它可以讓桌面.NET應用程序與繫留的移動設備進行通信。包裝起源於OpenNetCF project，但現在單獨管理。

您可以使用整個RAPI項目DLL，因爲它從該項目發運，或者只是使用您需要的代碼的子集。我需要在連接時在設備上創建文件，因此我不需要性能統計信息或Rapi中包含的設備註冊表內容。所以，我只是抓住了我所需要的3個源文件...

它爲我工作的方式，是這樣的：

• 1.用ActiveSync（DccManSink）來檢測移動設備的連接/斷開狀態
• 使用RAPI包裝將文件複製到設備，在設備上創建文件，從設備複製文件等等。
