仿QQ会员右下角提示框c#实现

为了不让大家再误会，我在这里声明，我做的是在登录后的提示，只要大家用过QQ，Q会员开通过就知道 的，

先看一下效果吧

说一下实现 吧，

第一步是先把QQ会员 便当 的框给截图下来，然后放到Ps里P一下，需要做到这样就行了，看图片

第二步，可以在上面加一 些Lable就行了，关闭按钮是两个图片，切换的方法是这样的

 //图片离开事件
        private void pictureBox1_MouseLeave(object sender, EventArgs e)
        {
            pictureBox1.BackgroundImage = ClientSystem.Properties.Resources.lgintop;
        }

        //图片进入事件
        private void pictureBox1_MouseEnter(object sender, EventArgs e)
        {
            pictureBox1.BackgroundImage = ClientSystem.Properties.Resources.lgintop1;
        }

第三步，IP的取法我就不说了有很多，还有上面的4.0的测试这些都 是加上的新闻，只要启动浏览器就行了，

启动的方法是

 //系统官网
        private void label7_Click(object sender, EventArgs e)
        {
            Process.Start("http://www.smxzc.com/");
        }

第四步，说一下渐变显示 的效果的处理方法

string caozuo = "";

//界面加载
        private void Messages_Load(object sender, EventArgs e)
        {
            try
            {
                //让窗体加载时显示到右下角
                int x = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Size.Width - 255;
                int y = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Size.Height - 161;
                this.SetDesktopLocation(x, y);

                //加载显示信息
                ShowComptureInfo();

                //渐变显示这里表示加载
                caozuo = "load";
                this.Opacity = 0;
            }
            catch (Exception)
            {

            }
        }

  caozuo有两个值一个是 load表示要向不透明方向增加量，也就是说会慢慢看清楚，还有一个close 表示要向透明方向增加量，这样会慢慢的看不到窗体

，我是用一个Timer来处理的

 //定时处理渐变的效果
        private void timer2_Tick(object sender, EventArgs e)
        {
            if (caozuo == "load")
            {
                this.Opacity += 0.09;
            }
            else if (caozuo == "close")
            {
                this.Opacity = this.Opacity - 0.09;
                if (this.Opacity == 0)
                    this.Close();
            }
        }

 这样只要caozuo的值发生变化的时候 就会向某个方向开始增加渐变显示 的量

当鼠标进入的时候我是这样处理的

 //进入窗体事件
        private void Messages_MouseEnter(object sender, EventArgs e)
        {
            //停止定时关闭
            timer1.Enabled = false;
            //开始渐变加载
            caozuo = "load";
        }

这样的话就会在原来的基础上加量，也就是说如果快不显示了，当鼠标移动进入窗体时就双会慢慢的显示，当移开的时候我是这样处理的

 //窗体离开事件
        private void Messages_MouseLeave(object sender, EventArgs e)
        {
            timer1.Enabled = true;
        }

  //定时关闭窗体
        private void timer1_Tick(object sender, EventArgs e)
        {
            timer2.Enabled = true;
            caozuo = "close";//关闭窗体
        }

 这样就双会启动定时关闭窗体，我的定时是6秒大家可以随便改的

效果就是这样实现的

 因为我的窗体 是没有标题栏的这样就不能拖动了， 很不方便，拖动窗体的方法有很多，我是这样实现 的，

 private bool isMouseDown = false;
        private Point FormLocation;     //form的location
        private Point mouseOffset;      //鼠标的按下位置

        //鼠标安下
        private void Messages_MouseDown(object sender, MouseEventArgs e)
        {
            try
            {
                if (e.Button == MouseButtons.Left)
                {
                    isMouseDown = true;
                    FormLocation = this.Location;
                    mouseOffset = Control.MousePosition;
                }
            }
            catch (Exception)
            {

            }
        }

        //鼠标移动
        private void Messages_MouseMove(object sender, MouseEventArgs e)
        {
            try
            {
                int _x = 0;
                int _y = 0;
                if (isMouseDown)
                {
                    Point pt = Control.MousePosition;
                    _x = mouseOffset.X - pt.X;
                    _y = mouseOffset.Y - pt.Y;

                    this.Location = new Point(FormLocation.X - _x, FormLocation.Y - _y);
                }
            }
            catch (Exception)
            {

            }
        }

        //鼠标松开
        private void Messages_MouseUp(object sender, MouseEventArgs e)
        {
            try
            {
                isMouseDown = false;
            }
            catch (Exception)
            {

            }
        }
