B4J Question ipconfig with jshell

[Isac]

I can not recall the cmd, what does not work?

you can recover ipconfig on a message box?

Dim J As Shell
J.Initialize("J","cmd.exe",Null)
   J.WorkingDirectory="C:\Windows\System32\cmd"
   J.Run(5000) 
   StartMessageLoop

thank you

 

[Erel]

Sub AppStart (Args() As String)
   Dim s As Shell
   s.Initialize("shl", "\windows\System32\ipconfig.exe", Null)
   s.Run(-1)
   StartMessageLoop
End Sub

Sub shl_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
   If Success Then
     Log(StdOut)
   End If
End Sub

 

[Isac]

does not work, out this error:

Waiting for debugger to connect...
Program started.
An error occurred:
(Line: 0) null
java.lang.Exception: Sub appstart signature does not match expected signature.

I'm sorry but it works, I used: NON - IU (console)

but how can I pull on a message box or else the output of ipconfig?
it's possible to do it?

ub shl_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
   Dim em As Msgboxes
   If Success Then
        em.Show(StdOut,"IPCONFIG")
     Log(StdOut)
   End If
End Sub

thanks Erel

You should use: fx.Msgbox(MainForm, StdOut.ToString, "IPCONFIG")

I also tried without ToString but always generates error:

Program terminated (StartMessageLoop was not called).

 

[jmon]

Just write "StdOut", instead of "StdOut.ToString"
[edit] sorry I see you tried already.

This maybe cause because you run a non-ui, and it cannot show the msgbox. Try with a UI b4j program.

 

[Isac]

ok solved

StartMessageLoop only works for 'Non-UI application




so I commented

   s.Initialize("shl", "\windows\System32\ipconfig", Null)
   s.Run(-1)
'   StartMessageLoop

Now comes a second problem:
when I enter ipconfig / all or netstat-a.........
does not work

maybe I have to add it in a different way?

   s.Initialize("shl", "\windows\System32\ipconfig/all", Null)
   s.Run(-1)
'   StartMessageLoop

 

[Isac]

ok solved

 s.Initialize("shl", "\windows\System32\ipconfig", _
Array As String("/all"))
   s.Run(-1)
