转：WinCE6.0 不重启修改IP地址

采用修改注册表的方式实现：
在应用程序中修改IP地址的方式：
 1 //////////////////////////////////////////////////////////////////////////
 2 // Set IP Address, Mask and Gateway 
 3 // Through the registry entry:
 4 // [HKEY_LOCAL_MACHINE/Comm/DM9CE1/Parms/TcpIp]
 5 // IpAddress, String
 6 // SubnetMask, String
 7 // DefaultGateway, String
 8 //////////////////////////////////////////////////////////////////////////
