Process.Start(screenreaderPath) 没有停留在屏幕上

Question

Private Sub Button8_Click(sender As Object, e As EventArgs) Handles Button8.Click
    Dim screenreaderPath As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "help.exe")
    Process.Start(screenreaderPath)

当我单击按钮时，它会加载但不会停留在屏幕上。相反，它只是消失了。谁能解释一下为什么？

Answer 1

由于这是一个命令行应用程序，您可以直接加载 cmd.exe 并向其传递 /k 参数，该参数告诉 Windows 保持 cmd 打开：

Private Sub Button8_Click(sender As Object, e As EventArgs) Handles Button8.Click
    Dim screenreaderPath As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "help.exe")
    Dim oProcess As New Process
    Dim pi As ProcessStartInfo = New ProcessStartInfo()

    pi.Arguments = " /k """ & screenreaderPath & """"
    pi.FileName = "cmd.exe"
    oProcess.StartInfo = pi
    oProcess.Start()
End Sub

Process.Start(screenreaderPath) 没有停留在屏幕上

Process.Start(screenreaderPath) not staying on screen
