WinCE系统获取远程服务器时间来设置本地时间
在做项目时用datalogic手持终端设备遇到一个问题，系统冷启动或断电后再启动这时系统的时间会还原掉，当然重新设置系统时间这是没问题的，但就是有点麻烦，每次都要设置，如果我们限制手持机的使用功能，比如说锁住桌面不让用户做其它操作，这时用户根本就没办法手动设置系统时间，那能不能能过代码获取远程服务器时间来设置本地时间呢？可通过ＡＰＩ来修改系统的时间，代码如下：1. 声明代码
//imports SetLocalTime function from kernel32.dll public static extern int SetLocalTime(ref SystemTime lpSystemTime); //struct for date/time apis public struct SystemTime { public short wYear; public short wMonth; public short wDayOfWeek; public short wDay; public short wHour; public short wMinute; public short wSecond; public short wMilliseconds; }
2. 调用代码示例：
try{ // 通过WebService获取服务器时间 SCM.SOAPService soap = new SCM.SOAPService(); DateTime remoteTime = soap.getSystemTime(); // 给结构体赋值 SystemTime newTime = new SystemTime(); newTime.wYear = (short)remoteTime.Year; newTime.wMonth = (short)remoteTime.Month; newTime.wDay = (short)remoteTime.Day; newTime.wHour = (short)remoteTime.Hour; newTime.wMinute = (short)remoteTime.Minute; newTime.wSecond = (short)remoteTime.Second; newTime.wMilliseconds = (short)remoteTime.Millisecond; newTime.wDayOfWeek = (short)remoteTime.DayOfWeek; // 设置本地时间 SetLocalTime(ref newTime);}catch { MessageBox.Show("获取服务器时间设置本地时间失败！", "错误提示",MessageBoxButtons.OK, MessageBoxIcon.Hand, MessageBoxDefaultButton.Button1);}
