如何通过互联网从手机访问桌面 [英] How to access desktop from mobile via internet

问题描述

您好，先生，
我是Gausiya，我们在远程桌面管理员上完成了一个项目，整个代码已在模拟器上成功运行，即在Wirelesstoolkit 2.5.2上.但是，当我们在启用了诺基亚2700 gprs的诺基亚移动设备上实际加载项目jar和jad fie时，它不会显示任何动作.
基本上，我们提供了远程桌面的IP地址和移动设备上的端口2000(如果已连接)，它将显示3个可选的桌面文件和帮助，如果单击桌面"，则它必须显示到我们提供IP的计算机的桌面.

但是，当我们输入ip和port时，它就没有显示任何内容.那么，您能指导我们解决这个问题吗?我们是否需要在移动设备或调制解调器上进行任何设置，所以请立即通过* REMOVED MAIL *答复我，我们的情况非常糟糕，请尽早答复.

Hello Sir,
I am Gausiya, we have done a project on Remote desktop administrator whole code is successfully running on the emulator i.e on Wirelesstoolkit 2.5.2. But when we actually load our projects jar and jad fie on a Nokia mobile 2700 gprs enabled then it does not show any kind of action.
Basically we are providing ip address of remote desktop and port 2000 on mobile if it get connected then it will display 3 option desktop files and help, if we click desktop then it has to show to desktop of computer whose ip we had provided.

But when we enter ip and port then it does not show anything on moible. So will you please guide us in this problem? Do we have to make any settings on mobile or on modem so reply me immediately on *REMOVED MAIL* we are in very bad conditon please reply as early as possible.
