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 description for Form1. /// public class Form1 : System.Windows.Forms.Form { private AxAgentObjects.AxAgent axAgent1;

/// /// Required designer variable. /// 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 // } /// /// Clean up any resources being used. /// protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #p# #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// 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(); // // textBox1 // 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.textBox1.Text = "Type anything here for the character to read for you!(Only English)"; // // button1 // this.button1.Location = new System.Drawing.Point(16, 24); this.button1.Name = "button1"; this.button1.TabIndex = 1; this.button1.Text = "导入精灵"; this.button1.Click += new System.EventHandler(this.button1_Click); // // button2 // this.button2.Location = new System.Drawing.Point(16, 80); this.button2.Name = "button2"; this.button2.TabIndex = 1; this.button2.Text = "朗读文本"; this.button2.Click += new System.EventHandler(this.button2_Click); // // button3 // 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); // // axAgent1 // 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); } #endregion /// /// The main entry point for the application. /// [STAThread] static void Main() { Application.Run(new Form1()); } 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 } } } 4.好了,现在完成了所有的工作了,安Ctrl+F5试试效果吧!
四.总结
从以上的例子,我们可以发现用C#做Windows平台下的开发是相当迅速而有效的。其实上面的例子还可以大大扩充,使之实现像电子小说阅读、英文听力测试、英文单词学习等功能,读者不妨一试。 |
