vb.net代码， UIautomation控制操作系统的计算器实现1+1=2

在VB.NET中使用UIAutomation库来控制操作系统计算器并实现1+1等于2的操作，首先需要安装Windows Automation Library (WIA) 动态链接库，然后编写代码。以下是一个简单的示例：

Imports Microsoft.VisualBasic.ApplicationServices
Imports System.Windows.Automation

Public Class CalculatorApp
    Private Const CALCULATOR_PATH As String = "Calculator.exe"

    Public Sub StartCalculator()
        ' 启动计算器进程
        Dim process As New ProcessStartInfo(CALCULATOR_PATH)
        process.WorkingDirectory = Environment.CurrentDirectory
        process.UseShellExecute = True
        process.Verb = "runas" ' 如果权限不够可以添加这个
        Process.Start(process)

        ' 给计算器一些时间启动
        Thread.Sleep(5000)

        ' 找到计算器窗口
        Using automation As AutomationElement = AutomationElement.FromHandle(Process.GetCurrentProcess().MainWindowHandle)
            ' 获取加法按钮
            Dim addButton As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "Add"))
            
            ' 点击加法按钮
            If addButton IsNot Nothing Then
                addButton.Invoke() ' 或者 addButton.Click() 如果UIA支持
            End If

            ' 输入数字1
            Dim numOne As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "7")) ' 这里假设7对应第一个数字键
            numOne.SetFocus()
            SendKeys.Send("1")

            ' 输入加号
            Dim plusButton As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "+"))
            plusButton.Invoke()

            ' 输入数字2
            Dim numTwo As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "8"))
            numTwo.SetFocus()
            SendKeys.Send("2")

            ' 点击等号
            Dim equalButton As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "="))
            equalButton.Invoke()

            ' 检查结果是否为2
            Dim result As AutomationElement = automation.FindFirst(TreeScope.Descendants, New PropertyCondition(AutomationElement.NameProperty, "显示屏"))
            Dim text As String = result.GetCurrentPropertyValue(AutomationElement.NameProperty).ToString()
            If text = "2" Then
                MessageBox.Show("计算成功：1 + 1 = 2")
            Else
                MessageBox.Show("计算失败，结果不是2")
            End If
        End Using
    End Sub
End Class

注意这只是一个基本示例，实际应用可能需要处理更多边缘情况，如输入延迟、错误处理等。此外，UI元素可能会随时间和系统更新而变化，因此可能需要调整查找策略。
