Winform 关于文字移动的问题！！？？
小弟现在想做一个关于label从下往上移动的窗体。基本功能已实现，但效果不理想，不理想在哪呢？在一段文字走完了以后，会出现一屏的空白。望大侠们赐教下！！！

基本代码如下：

  int loc_text = 0;
 private void timer1_Tick(object sender, EventArgs e)
        {
            int FWidth = this.panel1.Width;
            int FHeight = this.panel1.Height;

            Point LPos = new Point(this.label1.Location.X, this.label1.Location.Y);
            if (LPos.Y < FHeight)
            {
                if (LPos.Y < -loc_text)
                {
                    this.label1.Location = new Point(0, this.Height - 72); return;
                }

                this.label1.Location = new Point(LPos.X, LPos.Y - 10);
                return;
            }
            else
            {
                this.label1.Location = new Point(0, 0);
            }
        }


 private void JCZ_SendNews_Load(object sender, EventArgs e)
        {
            this.label1.Location = new Point(0, this.Height - 72);
            label1.Text = "      紧急通知\n由于近期物价高涨，燃油价格也高涨，反正就是什么都贵了。为了体现中国加入WTO与国际接轨的精神，本店铺也将提价10%，表示对国家的物质文明建设的贡献！";

            int sumChar = label1.Text.Length;
            int rowCount = (sumChar / 10) + 1;
            label1.Height = rowCount * 100;
            loc_text = rowCount * 100;
            label1.Size = new Size(1024, label1.Height);
            label1.Font = new Font("黑体", 72);
            label1.ForeColor = Color.Red;
            this.BackColor = Color.Black;

            this.timer1.Enabled = true; 
 
            this.timer1.Interval = 300;
            this.timer1.Start();

        }

窗体的尺寸为：1024，768 winform label 从下往上移动 timer
[解决办法]
if (LPos.Y < FHeight)
=>
if (LPos.Y+label1.Height < FHeight)
[解决办法]
不要用Timer。timer有段时间停顿的。
你用一个线程做。那个不会停顿的。

if (LPos.Y < -loc_text)判断不对，应该是
if (LPos.Y < -label1.Height)

        private void timer1_Tick(object sender, EventArgs e)
        {
            int FWidth = this.panel1.Width;
            int FHeight = this.panel1.Height;

            Point LPos = this.label1.Location;
            if (LPos.Y < FHeight)
            {
                if (LPos.Y < -label1.Height)
                {
                    this.label1.Location = new Point(0, this.Height - 72);
                    return;
                }

                this.label1.Location = new Point(LPos.X, LPos.Y - 10);
            }
            else
            {
                this.label1.Location = new Point(0, 0);
            }
        }


        private void JCZ_SendNews_Load(object sender, EventArgs e)
        {
            this.label1.Location = new Point(0, this.Height - 72);
            label1.Text = "      紧急通知\n由于近期物价高涨，燃油价格也高涨，反正就是什么都贵了。为了体现中国加入WTO与国际接轨的精神，本店铺也将提价10%，表示对国家的物质文明建设的贡献！";

            int sumChar = label1.Text.Length;
            int rowCount = (sumChar / 10) + 1; 
 
            label1.Height = rowCount * 100;
            label1.Size = new Size(1024, label1.Height);
            label1.Font = new Font("黑体", 72);
            label1.ForeColor = Color.Red;
            //this.BackColor = Color.Black;
            this.timer1.Enabled = true;
            this.timer1.Interval = 300;
            this.timer1.Start();

        }
