时间同步问题! 想写一个程序,把本机时间和Internet上的时间服务器的时间同步,应该如何做?? 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 没有别的方法了吗??好像Windows自带的时间同步一样!他是怎么做的呢??听说有个什么协议的!! 不需要实时同步 只要点一下按钮 然后同步时间 应该怎么做?? 就像Windowxp自带的那样 用api函数SetSystemTimeusing System;using System.Drawing;using System.Collections;using System.ComponentModel;using System.Windows.Forms;using System.Data;using System.Runtime.InteropServices;namespace WindowsApplication1{ [StructLayout(LayoutKind.Sequential)] public struct SystemTime { public ushort wYear; public ushort wMonth; public ushort wDayOfWeek; public ushort wDay; public ushort wHour; public ushort wMinute; public ushort wSecond; public ushort wMiliseconds; } public class Win32 { [DllImport("Kernel32.dll")] public static extern bool SetSystemTime( ref SystemTime sysTime ); [DllImport("Kernel32.dll")] public static extern void GetSystemTime(ref SystemTime sysTime); } /// <summary> /// Form1 的摘要说明。 /// </summary> public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.Button button1; private System.Windows.Forms.TextBox textBox1; private System.Windows.Forms.TextBox textBox2; /// <summary> /// 必需的设计器变量。 /// </summary> private System.ComponentModel.Container components = null; public Form1() { // // Windows 窗体设计器支持所必需的 // InitializeComponent(); // // TODO: 在 InitializeComponent 调用后添加任何构造函数代码 // } /// <summary> /// 清理所有正在使用的资源。 /// </summary> protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows 窗体设计器生成的代码 /// <summary> /// 设计器支持所需的方法 - 不要使用代码编辑器修改 /// 此方法的内容。 /// </summary> private void InitializeComponent() { this.button1 = new System.Windows.Forms.Button(); this.textBox1 = new System.Windows.Forms.TextBox(); this.textBox2 = new System.Windows.Forms.TextBox(); this.SuspendLayout(); // // button1 // this.button1.Location = new System.Drawing.Point(188, 174); this.button1.Name = "button1"; this.button1.TabIndex = 0; this.button1.Text = "button1"; this.button1.Click += new System.EventHandler(this.button1_Click); // // textBox1 // this.textBox1.Location = new System.Drawing.Point(56, 12); this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(510, 21); this.textBox1.TabIndex = 1; this.textBox1.Text = "textBox1"; // // textBox2 // this.textBox2.Location = new System.Drawing.Point(58, 50); this.textBox2.Name = "textBox2"; this.textBox2.Size = new System.Drawing.Size(506, 21); this.textBox2.TabIndex = 2; this.textBox2.Text = "textBox2"; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(6, 14); this.ClientSize = new System.Drawing.Size(602, 273); this.Controls.Add(this.textBox2); this.Controls.Add(this.textBox1); this.Controls.Add(this.button1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); } #endregion /// <summary> /// 应用程序的主入口点。 /// </summary> [STAThread] static void Main() { Application.Run(new Form1()); } private void button1_Click(object sender, System.EventArgs e) { textBox1.Text = DateTime.Now.ToLongDateString() + DateTime.Now.ToLongTimeString(); SystemTime sysTime = new SystemTime(); sysTime.wYear = Convert.ToUInt16(DateTime.Now.Year); sysTime.wMonth = Convert.ToUInt16(DateTime.Now.Month); //处置北京时间 int nBeijingHour = DateTime.Now.Hour - 8; if (nBeijingHour <= 0) { nBeijingHour += 24; sysTime.wDay= Convert.ToUInt16(DateTime.Now.Day - 1); sysTime.wDayOfWeek = Convert.ToUInt16(DateTime.Now.DayOfWeek - 1); } else { sysTime.wDay= Convert.ToUInt16(DateTime.Now.Day); sysTime.wDayOfWeek = Convert.ToUInt16(DateTime.Now.DayOfWeek); } sysTime.wHour = Convert.ToUInt16(nBeijingHour); sysTime.wMinute = Convert.ToUInt16(DateTime.Now.Minute); sysTime.wSecond = Convert.ToUInt16(DateTime.Now.Second); sysTime.wMiliseconds = Convert.ToUInt16(DateTime.Now.Millisecond); Win32.SetSystemTime(ref sysTime); textBox2.Text = DateTime.Now.ToLongDateString() + DateTime.Now.ToLongTimeString(); } }}至于取远程服务器的时间,得需要远程服务器提供一个取时间的接口 C#中的 Style的一个小问题 我想引用 webbrowser 类,而不是拖放控件 求关键字lock的简单应用实例 各位帮我想个英文名字! 拜托啦 帮忙看看这段XML代码 c#中SplitContainer的使用 .Net中如何获取文件的系统关联图标? 20分求解,dataset更新时候说无法找到 TableMapping['Table'] 或 DataTable“Table”。怎么回事? 怎样改变应用程序的启动图标? 怎么判断一个string是不是都是数字? 求vss6.0c的下载地址 .net面试题,大家帮顶!!
