局域網電腦遠程監控程序
包括服務器端和客戶端
在一臺機器運行服務器程序
客戶端運行客戶端程序
可以動態監視服務器的屏幕
能將鼠標和鍵盤事件傳過去，能進行一般的操作
運行環境:jdk1.4.1(能處理鼠標滾輪的事件)
我在三臺機器分別是
win2000 ad server
winXP PRofession
redhat linux 8.0
上進行了測試，都可以運行服務器端和客戶端，并能工作
支持一臺服務器多臺客戶端，大家一起操縱，呵呵

客戶端源程序已經編寫了，正在完善中。歡迎大家來信咨詢,在我的主頁已經公開源代碼了！


//客戶端源代碼：

使用方法：
先在服務器運行服務器端程序
再在客戶端運行客戶端程序(不要運行在一臺機器上，你會發現鼠標很希奇)
在客戶端右擊中間區域，單擊那個菜單項，輸入服務器的地址
ok
讓我繼續來完善
