18.3.5  测试DevComponents的hScrollBarAdv控件（1）

前面我们已经看过测试DevComponents的vScrollBarAdv和hScrollBarAdv控件的一种方法，是利用键盘操作来处理的。在这里，我们尝试用QTP.NET插件扩展技术来处理。

用C#编写插件扩展代码如下所示（在Visual Studio中创建.NET插件扩展代码的方法与前面介绍的一致）：

using System;
using Mercury.QTP.CustomServer;
using System.Windows.Forms;
using DevComponents.DotNetBar.ScrollBar;

namespace QuickTestCustomServer_vScrollBarAdv_hScrollBarAdv
{
    [ReplayInterface]
    public interface IScrollBarReplay
    {
        #region Wizard generated sample code (commented)
        void  SetValue(string NewValue);
        #endregion
    }
    /// <summary>
    /// Summary description for ScrollBar.
    /// </summary>
    public class ScrollBar :
        CustomServerBase,
        IScrollBarReplay
    {
        // You shouldn't call Base class methods/properties at the constructor
        // since its services are not initialized yet.
        public ScrollBar()
        {
            //
            // TODO: Add constructor logic here
            //
        }

        #region IRecord override Methods
        #region Wizard generated sample code (commented)
        /*      /// <summary>
        /// To change Window messages filter implement this method.
        /// The default implementation is to get only Control's window messages.
        /// </summary>
        public override WND_MsgFilter GetWndMessageFilter()
        {
            return WND_MsgFilter.WND_MSGS;
        }

        /// <summary>
        /// To catch window messages you should implement this method.
        /// Please note: This method is called just in case the CustomServer is running
        /// under QuickTest process.
        /// </summary>
        public override RecordStatus OnMessage(ref Message tMsg)
        {
            // TODO:  Add OnMessage implementation.
            return RecordStatus.RECORD_HANDLED;
        }
*/
        #endregion
        /// <summary>
        /// In case you extend Record process, you should add your Events handlers
        /// in order to listen to Control's Events.

        public override void InitEventListener()
        {
            #region Wizard generated sample code (commented)
            // Notice, You can add as many handlers as you need.
            // Adding OnMouseDown handler.
            Delegate  e = new System.Windows.Forms.MouseEventHandler (this.OnMouseDown);

            // Adds an event handler as the first handler of the event.
            // The first argument is the name of the event for which to listen.
            //         You must provide an event that the control supports.
            //         Use the .NET Spy to obtain the list of events supported by the control.
            // The second argument is the event handler delegate.

            AddHandler("MouseDown", e);
