QQ停靠方法3：

QQ停靠方法3：
 相对来说也是比较简单，首先右键解决方案添加类EcanQQ ，其次在要停靠的窗体上添加timer控件，enable设置为true,timer控件的Tick事件中写如下代码
  EcanQQ qqfrm = new EcanQQ();//实例化类EcanQQ
  int height = this.Height;
  EcanQQ.hide_show(this, ref height, timer1);//timer1_Tick时间调用函数qqfrm.hide_show(); 
 这样就可以实现停靠了。

EcanQQ 类的代码如下：
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

namespace QQ停靠4
{
    class EcanQQ
    {
        /// <summary>
       /// QQ吸附窗体
         /// </summary>
         /// <param name="frm">要吸附边缘的窗体</param>
         /// <param name="frmHeight">窗体的高度</param>
        /// <param name="timer">定时器控件</param>
         //用法：在对应窗体timer控件的Tick事件中写代码 int height = this.Height; EcanQQ.hide_show(this, ref height, timer1);
        
         public void hide_show(Form frm, ref int frmHeight, Timer timer)
         {
             if (frm.WindowState != FormWindowState.Minimized)
             {
                 timer.Interval = 100;               
                 if (Cursor.Position.X > frm.Left - 1 && Cursor.Position.X < frm.Right && Cursor.Position.Y > frm.Top - 1 && Cursor.Position.Y < frm.Bottom)
                 {
                     if (frm.Top <= 0 && frm.Left > 5 && frm.Left < Screen.PrimaryScreen.WorkingArea.Width - frm.Width)
                     {
                        frm.Top = 0;
                     }
                     else if (frm.Left <= 0)
                     {
                         frm.Left = 0;
                     }
                     else if (frm.Left + frm.Width > Screen.PrimaryScreen.WorkingArea.Width)
                     {
                         frm.Left = Screen.PrimaryScreen.WorkingArea.Width - frm.Width;
                     }
                     else
                     {
                         if (frmHeight > 0)
                         {
                             frm.Height = frmHeight;
                             frmHeight = 0;
                         }
                     }
                 }
                 else
                {
                     if (frmHeight < 1)
                    {
                         frmHeight = frm.Height;
                     }
                     if (frm.Top <= 4 && frm.Left > 5 && frm.Left < Screen.PrimaryScreen.WorkingArea.Width - frm.Width)
                     {
                         frm.Top = 3 - frm.Height;
                        if (frm.Left <= 4)
                         {
                             frm.Left = -5;
                         }
                         else if (frm.Left + frm.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4)
                         {
                            frm.Left = Screen.PrimaryScreen.WorkingArea.Width - frm.Width + 5;
                         }
                     }
                     else if (frm.Left <= 4)
                    {
                        frm.Left = 3 - frm.Width;
                     }
                    else if (frm.Left + frm.Width >= Screen.PrimaryScreen.WorkingArea.Width - 4)
                     {
                        frm.Left = Screen.PrimaryScreen.WorkingArea.Width - 3;
                     }
                 }
            }
         }
     }
