如何将批处理的输出重定向到VB 2010 Express中的textbox1？ [英] How can I re-direct the output of a batch to the textbox1 in VB 2010 Express?

问题描述

所以我已经研究了这个约3天了，我发现的一切都不起作用或引发10+错误。我正在尝试从批处理文件（显示生成的字符串的CMD窗口）中获取输出并将其插入到我的VB Form1上的TextBox1中。因此，当我按下按钮时，批处理会打开（在工具栏上）一个CMD窗口，显示字符串，因为它们在插入可能是打开的文件对话框时生成，但现在是文本框。（多行）

有没有办法做到这一点和/或这是创建管道进来的地方？我提前道歉我是一个一周大的初学者。以下是我对button1的看法。

So I have researched this for about 3 days now and everything that I find doesn't work or throws 10+ Errors. I am trying take the output from a batch file (CMD Window that shows generated strings) and insert it into TextBox1 on my VB Form1. So when I push the button, the batch is executed which opens up (on toolbar) a CMD window, shows the strings as they are produced while being inserted into what might be an open file dialog but for now its textbox1.(multiline)
Is there a way to do this and/or is this where create pipeline comes in? I apologize in advance I am a week old beginner. Below is what I have for button1.

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Shell("C:\Test.bat")

    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
        Dim myprocess As New Process
        Dim StartInfo As New System.Diagnostics.ProcessStartInfo
        StartInfo.FileName = "cmd" 'starts cmd window
        StartInfo.RedirectStandardInput = True
        StartInfo.RedirectStandardOutput = True
        StartInfo.UseShellExecute = False 'required to redirect
        StartInfo.CreateNoWindow = True '<---- creates no window, obviously
        myprocess.StartInfo = StartInfo
        myprocess.Start()
        Dim SR As System.IO.StreamReader = myprocess.StandardOutput
        Dim SW As System.IO.StreamWriter = myprocess.StandardInput
        SW.WriteLine(TextBox1) 'the command you wish to run.....
        SW.WriteLine("exit") 'exits command prompt window
        txtResults.Text = SR.ReadToEnd 'returns results of the command window
        SW.Close()
        SR.Close()
    End Sub
End Class

推荐答案

如果TextBox1包含要执行的命令，为什么不简单地将其作为StartInfo.Arguments传递？

看看这个;那里可能有一些有用的东西：

ProcessCommunicator [ ^ ]





此外，您不需要创建新的StartInfo。

If TextBox1 contains the command to execute, why not simply pass it as StartInfo.Arguments?

Have a look at this; there might be something useful in there:
ProcessCommunicator[^]


Also, you don't need to create a new StartInfo.
