我的问题是:C#中,怎样使用TabContronl来实现多选项卡,请详细的给出每一步和相关的代码(VBasic2010、VC#2010），最好配上附图。急！！

以下给出一个示例（在文本框输入地址后回车，将自动创建新选项卡，地址栏网页之后自动显示）

【Form1的设计界面代码Form1.designer.cs】

partial class Form1
    {
        /// <summary>
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary>
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

        #region Windows Form Designer generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InitializeComponent()
        {
            this.tableLayoutPanel1 = new System.Windows.Forms.TableLayoutPanel();
            this.textBox1 = new System.Windows.Forms.TextBox();
            this.tabControl1 = new System.Windows.Forms.TabControl();
            this.tableLayoutPanel1.SuspendLayout();
            this.SuspendLayout();
            // 
            // tableLayoutPanel1
            // 
            this.tableLayoutPanel1.ColumnCount = 1;
            this.tableLayoutPanel1.ColumnStyles.Add(new System.Windows.Forms.ColumnStyle(System.Windows.Forms.SizeType.Percent, 100F));
            this.tableLayoutPanel1.Controls.Add(this.textBox1, 0, 0);
            this.tableLayoutPanel1.Controls.Add(this.tabControl1, 0, 1);
            this.tableLayoutPanel1.Dock = System.Windows.Forms.DockStyle.Fill;
            this.tableLayoutPanel1.Location = new System.Drawing.Point(0, 0);
            this.tableLayoutPanel1.Name = "tableLayoutPanel1";
            this.tableLayoutPanel1.RowCount = 2;
            this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 10F));
            this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, 80F));
            this.tableLayoutPanel1.Size = new System.Drawing.Size(292, 273);
            this.tableLayoutPanel1.TabIndex = 0;
            // 
            // textBox1
            // 
            this.textBox1.Dock = System.Windows.Forms.DockStyle.Fill;
            this.textBox1.Location = new System.Drawing.Point(3, 3);
            this.textBox1.Name = "textBox1";
            this.textBox1.Size = new System.Drawing.Size(286, 21);
            this.textBox1.TabIndex = 0;
            this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.textBox1_KeyPress);
            // 
            // tabControl1
            // 
            this.tabControl1.Dock = System.Windows.Forms.DockStyle.Fill;
            this.tabControl1.Location = new System.Drawing.Point(3, 33);
            this.tabControl1.Name = "tabControl1";
            this.tabControl1.SelectedIndex = 0;
            this.tabControl1.Size = new System.Drawing.Size(286, 237);
            this.tabControl1.TabIndex = 1;
            // 
            // Form1
            // 
            this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
            this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
            this.ClientSize = new System.Drawing.Size(292, 273);
            this.Controls.Add(this.tableLayoutPanel1);
            this.Name = "Form1";
            this.Text = "Form1";
            this.Load += new System.EventHandler(this.Form1_Load);
            this.tableLayoutPanel1.ResumeLayout(false);
            this.tableLayoutPanel1.PerformLayout();
            this.ResumeLayout(false);

        }

        #endregion

        private System.Windows.Forms.TableLayoutPanel tableLayoutPanel1;
        private System.Windows.Forms.TextBox textBox1;
        private System.Windows.Forms.TabControl tabControl1;

    }

【Form1的cs后台运行代码】

 public partial class Form1 : Form
    {
        int counter = 0;

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            //敲下回车，创建一个新页面（假设输入没有http……)
            if (e.KeyChar == (char)13)
            {
                string url = textBox1.Text;
                Uri uri = null;
                if (url.IndexOf("http://") < 0)
                {
                    url = "http://" + url;
                }
                //判断是否可以转化成一个正常的url
                if (Uri.TryCreate(url, UriKind.Absolute, out uri))
                {
                    //不存在，直接添加
                    if (tabControl1.TabPages[url] == null)
                    {
                        tabControl1.TabPages.Add(url, (++counter).ToString());
                        //动态添加WebBrowser，并指定url打开预览
                        WebBrowser wb = new WebBrowser();
                        wb.Dock = DockStyle.Fill;
                        wb.Url = uri;
                        tabControl1.TabPages[url].Controls.Add(wb);
                    }

                    //把页面切换为当前的
                    tabControl1.SelectedTab = tabControl1.TabPages[url];
                }
            }
        }
    }
