之前玩過　NET Framework
我大概知道方法, 不過說起來有點麻煩 ! !
而且, 也不知道你有沒有 "工具" 可以搞~
(eMbedded Visual C++, 或 Visual Studio .NET 2003 之類的 )

您是拿到什麼樣的模擬器? 是只有 Emulator.exe 執行檔嗎 ? 還是..... ??
得先知道您的環境, 還有所試過的方法, 小弟才能知道從那兒開始 ,
不然...真的得弄一大堆過程圖出來看哦

先給您一些從 MSDN library 找來的文章瞧瞧 ...

How to: Use ActiveSync with the Emulator

Connecting to the emulator through ActiveSync is important for convenience in moving files between the desktop computer and the emulator,
as well as for testing and debugging custom ActiveSync synchronization providers.
The emulator supports ActiveSync between the host computer (with Microsoft ActiveSync version 3.7 installed) and the emulator image.

To use ActiveSync with the emulator,
two available serial ports on the development workstation and a serial cable are required.
The cable should be a straight-through cable, sometimes called an extension or a null modem cable (Belkin part number F2N209-6 or equivalent).

其它的得您自個兒先去上面的網址看原文章囉 ...

至於是不是還有其它更好更簡易的方法，我還不知道∼
