Eclipse中使用Emacs键绑定:
??2004-07-10 09:37:26 from http://tendant.mysmth.net

今天发现了原来eclipse 中也有emacs 键绑定的功能，haha

试用了一下发现真得很不错，建议喜欢emacs的兄弟使用。

使用方法：

window->perference->workbench£->keys->active configuraion

选emacs 就ok.

前一段偶也尝试使用emacs 中的jde，但是不是特别好用，可能是我自己还不太会用吧，不过最近也没有时间去整它了，就用eclipse 自带的这个功能就很不错了。

另外：小日本有人写了个eclipse 的emacs 插件，我试用了一下由于很多键冲突需要重新定义就没有再尝试了。它的主页在：http://park.ruru.ne.jp/ando/work/who/ee2e/。

在找这个东东时也在sourceforge 上发现了另外一个eclipse 编辑器功能增强插件。

获取指定IP的终端的MAC地址 :

  因为业务需要，需要给公司部分终端进行登记，以保证授权终端能够登录业务系统，最好的方法就是记录下每台终端的mac地址来进行验证是否有授权。

  下面是采用调用api的方式获取指定ip的终端的mac地址：

 [dllimport("iphlpapi.dll")]
 public static extern int sendarp(int32 dest, int32 host, ref int64 mac, ref int32 length);
 //dest为目标机器的ip;host为本机器的ip

 [dllimport("ws2_32.dll")]
 public static extern int32 inet_addr(string ip);

 public static string getnetcardaddress(string strip)
 {
 try
 {
 iphostentry host = dns.gethostbyname(system.environment.machinename);
 int32 local = inet_addr(host.addresslist[0].tostring());
 int32 remote = inet_addr(strip);
