vb.net传输汉字的简单介绍
vb.net 加载的新窗口 里面会有传值 数字没问题 中文是乱码 该如何 解决呢 谢谢
一般出现乱码都是在js裏面跳转到哪个类然後得到这个参数的时候中文乱码,有一个非常实用的法,在js你可以这样写:varurl=..;url=encodeURI(url);url=encodeURI(url);//最重要的部分,两次调用encodeURI,就是编码两次然後在跳转到url所在的类,获取这个参数的方法如下:Stringname=request.getParameter("name");name=URLDecoder.decode(name,"utf8");这样就能解决乱码问题了,这种方法还没遇到过不能解决的乱码,

vb.net怎么在非局域网的两个电脑之间互传文字信息？
如果你家里是公网ip或者公网IP能映射内网IP的话可以直接搭一个服务器，否则只能使用内网穿透软件然后再搭建服务器。如应用服务器、网页服务器、电子邮件服务、 FTP 服务器等等都可以进行消息交流。
