本文介绍了一个简单的Windows窗体应用程序，该程序使用定时器和FlashWindow函数实现窗口的闪烁效果。通过两个定时器交替控制pictureBox的可见性和窗口的闪烁状态，以此吸引用户的注意力。

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace Case01_4 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } //声明FlashWindow函数 [System.Runtime.InteropServices.DllImportAttribute("user32.dll")] public static extern bool FlashWindow(IntPtr handle, bool bInvert); private void Form1_Load(object sender, EventArgs e) { this.timer1.Enabled = true; this.timer1.Interval = 500; this.timer2.Enabled = false; this.timer2.Interval = 260; } private void timer1_Tick(object sender, EventArgs e) { FlashWindow(this.Handle, true); pictureBox1.Visible = true; timer1.Enabled = false; timer2.Enabled = true; } private void timer2_Tick(object sender, EventArgs e) { FlashWindow(this.Handle, true); pictureBox1.Visible = false; timer2.Enabled = false; timer1.Enabled = true; } private void pictureBox1_Click(object sender, EventArgs e) { } } }
