在C#下用Microsoft Agent创建超酷语言精灵(附图)



C#作为Microsoft .Net战略下的新兴语言,有其不可比拟的强大功能。作为一种RAD语言,它有Visual Basic快速开发应用程序的优点,又不乏C++语言的面相对象的优良特性。

本文就通过介绍利用Microsoft Agent来创建一个超酷用户界面(就像Office2000那种办公助手的界面,并有语音朗读功能)来向大家展示一下用C#进行Windows应用程序快速开发的优点。

一 概述

微软的Office2000中用到了一些被称为“办公助手”(Office Assistance)的精灵来给用户提供帮助,这样做的效果是显而易见的,大家可以得到很有效的帮助并且使用户界面显得非常友好。现在,我们只要使用Microsoft Agent(基于COM),我们就可以在自己的程序中使用这种精灵来给程序增光添彩。用这种精灵,我们可以实现语音的朗读、表演动画甚至还可以实现语音识别呢!

二 要求
(1)微软公司视窗2000服务器版或视窗 XP 版
(2).Net FrameWrok SDK Beta 2版
(3)Microsoft Agent核心组建
(4)Microsoft Agent的精灵:吉尼(Genie)、么林(Merlin)、罗比(Robby)和皮蒂(Peedy)
(5)至少有一个英语的Text-to-Speech引擎(现在还找不到中文的)
(6)微软运行时发音API4.0a
(如果还要实现语音识别功能的话,还要有微软的语音识别引擎)
所有这些都可以在http://microsoft.com/msagent/downloads.htm下载。另外,必须要安装Office2000(Office97是不行的)。

三 实现方法
1.打开VS.Net,新建一个工程,不妨取名为CoolUI。图示如下:

2.创建用户界面。
选择菜单:工具->自定义工具箱,并选择Microsoft Agent Control 2.0组件,图示

将Microsoft Agent Control控件添加到窗体上(在程序运行时是看不到窗体是的Microsoft Agent控件的,只有在设计界面时它才显示出来),并课设计窗体如下:

将主窗体的Text属性设置为“CoolUI”;将左边三个按钮的Text属性分别设置为“导入精灵”、“朗读文本”、“隐藏精灵”;将textBox的Text属性设置为“Type anything here for the character to read for you!(Only English)”,Multiline属性设置为True。

3.简单的用户界面已经完成,现在我们来进行代码部分的工作:
首先,添加using AgentObjects;到代码的开始处。其次,在我们的类里添加私有数据成员:private IAgentCtlCharacterEx Character;(这就是我们要用到的精灵的对象)。修改构造函数如下:
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
button2.Enabled=false;//先使下面的两个按钮无效
button3.Enabled=false;

//
// TODO: Add any constructor code after InitializeComponent call
//
}
接着,添加左边三个按钮的鼠标单击的消息相应函数:
private void button1_Click(object sender, System.EventArgs e)
private void button2_Click(object sender, System.EventArgs e)
private void button3_Click(object sender, System.EventArgs e)
代码如下:
private void button1_Click(object sender, System.EventArgs e)
{
axAgent1.Characters.Load("Genie", (object)"GENIE.ACS");//导入吉尼这个精灵
Character = axAgent1.Characters["Genie"];
Character.LanguageID = 0x409;//把语言设置为英语,这里不能是中文

Character.Show(null);//显示精灵

button1.Enabled=false;//重新设置按钮的有效性
button2.Enabled=true;
button3.Enabled=true;
}

private void button2_Click(object sender, System.EventArgs e)
{
if(textBox1.Text.Length == 0) //如果没有字符的话,就不读
return;

Character.Speak(textBox1.Text, null);//让精灵朗读文本
}

private void button3_Click(object sender, System.EventArgs e)
{
Character.Play("Wave");
Character.Play("Hide");//隐藏精灵
}

所有完整的代码如下:
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
using AgentObjects;

namespace CoolUI
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private AxAgentObjects.AxAgent axAgent1;
private IAgentCtlCharacterEx Character;

private System.Windows.Forms.TextBox textBox1;
private System.Windows.Forms.Button button1;
private System.Windows.Forms.Button button2;
private System.Windows.Forms.Button button3;
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;

public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeComponent();
button2.Enabled=false;//先使下面的两个按钮无效
button3.Enabled=false;

//
// TODO: Add any constructor code after InitializeComponent call
//
}

/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

private void InitializeComponent()
{
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Form1));
this.textBox1 = new System.Windows.Forms.TextBox();
this.button1 = new System.Windows.Forms.Button();
this.button2 = new System.Windows.Forms.Button();
this.button3 = new System.Windows.Forms.Button();
this.axAgent1 = new AxAgentObjects.AxAgent();
((System.ComponentModel.ISupportInitialize)(this.axAgent1)).BeginInit();
this.SuspendLayout();
//

this.textBox1.Location = new System.Drawing.Point(112, 24);
this.textBox1.Multiline = true;
this.textBox1.Name = "textBox1";
this.textBox1.Size = new System.Drawing.Size(224, 152);
this.textBox1.TabIndex = 2;

this.button1.Click += new System.EventHandler(this.button1_Click);
//

this.button2.Name = "button2";

//

//
this.button3.Location = new System.Drawing.Point(16, 136);
this.button3.Name = "button3";
this.button3.TabIndex = 1;
this.button3.Text = "隐藏精灵";
this.button3.Click += new System.EventHandler(this.button3_Click);
//

//
this.axAgent1.Enabled = true;
this.axAgent1.Location = new System.Drawing.Point(320, 176);
this.axAgent1.Name = "axAgent1";
this.axAgent1.OcxState = ((System.Windows.Forms.AxHost.State)(resources.GetObject("axAgent1.OcxState")));
this.axAgent1.Size = new System.Drawing.Size(32, 32);
this.axAgent1.TabIndex = 0;
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);
this.ClientSize = new System.Drawing.Size(360, 213);
this.Controls.AddRange(new System.Windows.Forms.Control[] {
this.button3,
this.button2,
this.textBox1,
this.button1,
this.axAgent1});
this.Name = "Form1";
this.Text = "CoolUI";
((System.ComponentModel.ISupportInitialize)(this.axAgent1)).EndInit();
this.ResumeLayout(false);

}
