How to get the realtime content of cmd?

[gaxjyxq]

Hello,

I want to get the cmd window content in realtime from a command line (Dism.exe /Online /Cleanup-Image /AnalyzeComponentStore) in Windows 8 or 8.1

My code is below, but i can not get the progress percent values in realtime into the textbox, why?

Note: Need to untick the "Primarily 32bit" in the project compiling options in 64bit OS.

AddHandler p.OutputDataReceived, AddressOf Process_OutputDataReceived

p.BeginOutputReadLine()
p.WaitForExit()
p.Close()

If txtResult.InvokeRequired Then
txtResult.Invoke(New DataReceivedEventHandler(AddressOf Process_OutputDataReceived), sender, e)
Else
txtResult.Text += String.Format("{0}{1}", e.Data, Environment.NewLine)
End If
