1、使用 API 的 AnimateWindow 函数 定义 AnimateWindows
using System;using System.Runtime.InteropServices;
namespace Fountain.WinForm.MessageBoxDemo{ public class Win32 { /// summary /// 自左向右显示窗口,该标记可以在迁移转变动画和滑动动画中应用。应用AW_CENTER标记时忽视该标记 /// /summary public const int AW_HOR_POSITIVE 0x0001; /// summary /// 自右向左显示窗口,该标记可以在迁移转变动画和滑动动画中应用。应用AW_CENTER标记时忽视该标记 /// /summary public const int AW_HOR_NEGATIVE 0x0002; /// summary /// 自顶向下显示窗口,该标记可以在迁移转变动画和滑动动画中应用。应用AW_CENTER标记时忽视该标记 /// /summary public const int AW_VER_POSITIVE 0x0004; /// summary /// 自下向上显示窗口,该标记可以在迁移转变动画和滑动动画中应用。应用AW_CENTER标记时忽视该标记该标记 /// /summary public const int AW_VER_NEGATIVE 0x0008; /// summary /// 若应用了AW_HIDE标记,则使窗口向内重叠;不然向外扩大 /// /summary public const int AW_CENTER 0x0010; /// summary /// 隐蔽窗口 /// /summary public const int AW_HIDE 0x10000; /// summary /// 激活窗口,在应用了AW_HIDE标记后不要应用这个标记 /// /summary public const int AW_ACTIVE 0x20000; /// summary /// 滑动类型动画结果,默认为迁移转变动画类型,当应用AW_CENTER标记时,这个标记就被忽视 /// /summary public const int AW_SLIDE 0x40000; /// summary /// 淡入淡出结果 /// /summary public const int AW_BLEND 0x80000; /// summary /// 窗体动画函数 /// /summary /// param namehwnd/param /// param namedwTime/param /// param namedwFlags/param /// returns/returns [DllImport(user32)] public static extern bool AnimateWindow(IntPtr hwnd, int dwTime, int dwFlags); }}
定义显示消息窗体
using System;using System.Drawing;using System.Windows.Forms;
namespace Fountain.WinForm.MessageBoxDemo{ public partial class FormMessageBox : Form { /// summary /// 关闭窗口的定时器 /// /summary private Timer formCloseTime new Timer(); /// summary /// 构造方法 /// /summary public FormMessageBox() { InitializeComponent(); } /// summary /// 窗体加载 /// /summary /// param namesender/param /// param namee/param private void FormMessageBox_Load(object sender, EventArgs e) { // 手动设置起始位置 this.StartPosition FormStartPosition.Manual; // 计算屏幕尺寸并将窗体放置在右下角 Rectangle screenRectangle Screen.PrimaryScreen.WorkingArea; int x screenRectangle.Width - this.Width; int y screenRectangle.Height - this.Height; this.Location new Point(x, y); this.TopMost true;Win32.AnimateWindow(this.Handle, 1000, Win32.AW_SLIDE Win32.AW_VER_NEGATIVE);this.ShowInTaskbar false;formCloseTime.Interval 5000; formCloseTime.Tick new EventHandler(formCloseTime_Tick); formCloseTime.Start(); } /// summary /// 关闭窗口的定时器响应事件 /// /summary /// param namesender/param /// param namee/param private void formCloseTime_Tick(object sender, EventArgs e) { formCloseTime.Stop(); this.Close(); } /// summary /// /// /summary /// param namesender/param /// param namee/param private void FormMessageBox_FormClosed(object sender, FormClosedEventArgs e) { formCloseTime.Stop(); formCloseTime.Dispose(); Win32.AnimateWindow(this.Handle, 1000, Win32.AW_SLIDE Win32.AW_VER_POSITIVE Win32.AW_HIDE); } }}
主界面调用
FormMessageBox formMessageBox new FormMessageBox();formMessageBox.Show(); 2、控制窗体显示 定义显示消息窗体
using System;using System.Drawing;using System.Threading;using System.Windows.Forms;
namespace Fountain.WinForm.MessageBoxDemo{ public partial class FormNotifyBox : Form { /// summary /// 关闭窗口的定时器 /// /summary private System.Windows.Forms.Timer formCloseTime new System.Windows.Forms.Timer(); /// summary /// /// /summary private Point formPoint; /// summary /// /// /summary public FormNotifyBox() { InitializeComponent(); this.formPoint new Point(Screen.PrimaryScreen.WorkingArea.Width - this.Width, Screen.PrimaryScreen.WorkingArea.Height); // 设置窗体在屏幕右下角显示 this.Location formPoint; } /// summary /// /// /summary /// param namesender/param /// param namee/param private void FormNotifyBox_Load(object sender, EventArgs e) { try { formCloseTime.Interval 5000; formCloseTime.Tick new EventHandler(formCloseTime_Tick); formCloseTime.Start(); this.TopMost false; this.BringToFront(); this.TopMost true; this.PointToClient(this.formPoint); this.Location this.formPoint; this.Show(); for (int i 0; i this.Height; i) { this.Location new Point(formPoint.X, formPoint.Y - i); // 消息框弹出速度数值越大越慢 Thread.Sleep(1); } } catch (Exception exception) { } } /// summary /// 关闭窗口的定时器响应事件 /// /summary /// param namesender/param /// param namee/param private void formCloseTime_Tick(object sender, EventArgs e) { formCloseTime.Enabled false; for (int i 0; i this.Height; i) { //弹出框向下移动消失 Point point new Point(this.Location.X, this.Location.Y i); this.PointToScreen(point); //即时转换成屏幕坐标 this.Location point; //下降速度调节数字越小消失的速度越快建议不大于10 Thread.Sleep(8); } this.Close(); this.Dispose(); } }}
主界面调用
FormNotifyBox notifyForm new FormNotifyBox();notifyForm.Show();
