Help with command line Background Process on Vb.Net

[josedavido]

Hello friends.

I've just started a very simple project on Vb.Net
It is a software for send commands to Android devices trhough Android Data Bridge (ADB).

The problem is that every time I send a command my software stucksn then I have to run the Task Manager and finish the process manually. After that, my software shows the information gotten from ADB.

This is very annoying.

So, I thing that it could be solved if I sedn and recive information from ADB trough background process.

Aoreciate any help or guide.

This is the code for send and recive:

Public Sub Execute_command(ByVal Argumentos As String)
Try
RichTextBox3.Clear()
Dim p As New Process()
With p.StartInfo
.UseShellExecute = False
.WindowStyle = ProcessWindowStyle.Hidden
.RedirectStandardOutput = True
.RedirectStandardError = True
.CreateNoWindow = True
.FileName = AppDomain.CurrentDomain.BaseDirectory & "ADB/adb.exe"
.Arguments = Argumentos
End With

p.Start()
Do While Not p.StandardOutput.EndOfStream
RichTextBox3.Text = RichTextBox3.Text &(p.StandardOutput.ReadLine) & vbNewLine
RichTextBox3.ScrollToCaret()
Loop

Application.DoEvents()

RichTextBox3.Text = RichTextBox3.Text & p.StandardError.ReadToEnd
RichTextBox3.Text = RichTextBox3.Text & vbNewLine
RichTextBox3.ScrollToCaret()

p.Dispose()


Catch ex As Exception
MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub

Yes man, I know this object, but I've never used before for send commands and show answers on RichTextBox.

If you can make an example or give me more guide about it, I'll apreciate that.
