Test Run:MS UI Automation Library

1. Refer to : http://msdn.microsoft.com/en-us/magazine/cc163288.aspx

2. Tools: MS Spy++

3. Key MS Library: UIAutomationClient.dll & UIAutomationTypes.dll

4. Required Preperation: Before debugging you should turn off the managed Debugging Assistant for the "NonComVisibleBaseClass" exception. In Visual Studio,

1. Navigate to Debug->Exceptions...
2. Expand "Managed Debugging Assistants"
3. Uncheck the NonComVisibleBaseClass Thrown option.
4. Click [Ok]

Sample Demo codes by myself as follows:

-----------------------Form1.cs (server role) ----------------------------------------------

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace StrartCalcu
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.button1.Click+=new EventHandler(Click_CalculateBtn);
}

protected void Click_CalculateBtn(Object sender, EventArgs e)
{
String inputTxt = this.textBox1.Text;
String[] strArray = null;
//  char[] sep = { ' ' };
if (inputTxt == "" || inputTxt == null)
{
return;
}
else
{
strArray = inputTxt.Split(' ');
double pValue1 = Double.Parse(strArray[0]);
double pValue2 = Double.Parse(strArray[1]);
if (radioButton1.Checked)
{
//textResult.Text="btn1";
// add
textResult.Text = (pValue1 + pValue2).ToString();

}
if (radioButton2.Checked)
{
// textResult.Text = "btn2";
//sub
textResult.Text = (pValue1 - pValue2).ToString();
}
if (radioButton3.Checked)
{
//textResult.Text="btn3";
// multi
textResult.Text = (pValue1 * pValue2).ToString();
}
}

}

private void testBtn_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
