Shell and Stuff

I am writting a program that runs different shell commands. One of the shell commands starts downloading files from a remote location. When you run the shell command the shell pops up and shows the amount of data received. Is there a way to grab that info from the shell and hide the shell and display it on the VB GUI?

Any thoughts on this would be great!

Thanks!

Yes its possible. Here is a program I did. It runs the ipconfig command from the command prompt, captures the output and puts it in a textbox.

Its in C#, but it should'nt be a problem to convert.

I really appreciate that, but I can't open up the file because I don't have c# installed...

Also would that have allowed for continuous updating?


Thanks!

Use notepad to open the ".cs" files. Also, what do you mean by continous updating?

well the data streams, so it will take from 1 minute to many hours to stream the data - i want to constantly show how the progress is

Also while we are on the topic of shell, I am also having this other problem.

I am running this command:
Shell("c:\replaypc\replaypc " & ipaddress & " -d > text.dat ", AppWinStyle.MaximizedFocus, True)

it is supposed to write the output to the text.dat file. For some reason it is not writting it. Though if I go to the command line and type this in it does!
Do you know why?

I looked through your code... I see the proc...

when I do:

proc = new Process()

I don't know what type of variable to declare proc

Here is the vb code:

VB Code:

Dim proc As Process
 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        proc = New Process()
 
        Dim str As String = Nothing
        Dim sIn As StreamWriter
        Dim sOut As StreamReader
 
        proc.StartInfo.FileName = "ipconfig"
        proc.StartInfo.Arguments = " /all"
        proc.StartInfo.UseShellExecute = False
        proc.StartInfo.RedirectStandardInput = True
        proc.StartInfo.RedirectStandardOutput = True
        proc.StartInfo.RedirectStandardError = True
        proc.Start()
 
        sIn = proc.StandardInput
        sIn.AutoFlush = True
        sOut = proc.StandardOutput
 
 
        sIn.Write(Environment.NewLine)
        sIn.Write("exit" + Environment.NewLine)
        str = sOut.ReadToEnd()
 
        If (Not proc.HasExited) Then
            proc.Kill()
        End If
 
        TextBox2.Clear()
        TextBox2.Text = str
 
        sIn.Close()
        sOut.Close()
End Sub

Dont use the Shell command. Use the process class.

that code looks great, but what about the StreamWriter and StreamReader? It says the two are not defined...

bump

They should be. I tried it and it worked.

Copy and paste the code in a button click method.

for some reason I had to type in system.io.streamreader

the just streamreader would not work...

Oh, forgot to tell you. You have to put Import System.IO at the top of the program.

Is there a way to send a command to have the window minimized? Also this isn't working exactly as I would like because the vb code waits to do something until after the code is executed... Which means it isn't streaming on the vb app what is happening - like the amount of data being downloaded.
