C#窗体MessageBox显示自动消失(移动开发Pocket PC 2003)
MessageBox提示框一般需要手动关闭，对于简单的信息提示，每次还要去关闭很麻烦。于是想到怎样能让MessageBox显示一段时间后自动关闭。虽然知道这肯定要用到定时器之类的，由于知识所限，最终没能够解决，于是求助袁小萍师姐，师姐就是师姐啊，不用太多时间就搞定了~，下面是代码：using System;using System.Collections.Generic;using System.Text;using System.Runtime.InteropServices;using System.Windows.Forms;namespace pdaTraceInfoPlat.beans{ class MessageBoxTimeOut { private string _caption; public void Show(string text, string caption, int timeout) { this._caption = caption; StartTimer(timeout); MessageBox.Show(text, caption); } private void StartTimer(int interval) { Timer timer = new Timer(); timer.Interval = interval; timer.Tick += new EventHandler(Timer_Tick); timer.Enabled = true; } private void Timer_Tick(object sender, EventArgs e) { KillMessageBox(); //停止计时器 ((Timer)sender).Enabled = false; } private extern static IntPtr FindWindow(string lpClassName, string lpWindowName); public static extern int PostMessage(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam); public const int WM_CLOSE = 0x10; private void KillMessageBox() { //查找MessageBox的弹出窗口,注意对应标题 IntPtr ptr = FindWindow(null, this._caption); if (ptr != IntPtr.Zero) { //查找到窗口则关闭 PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero); } } }}
