Obtener retorno de consola en un tetxtbox o richtext. Ayuda
« en: 12 Abril 2021, 04:36 am »

Hola, necesito leer el retorno de consola, en un textbox, un richtextbox
Encontré algo que me sirve, pero no para todas las aplicaciones de consola.
Por ej, comando de win, ping, route, etc va.
Pero si quiero leer el valor leido desde una consola fastboot (ya todos la conocen)

la pantalla queda negra.

adjunto code

Código:
Private Sub Command1_Click()
    Dim Exec As String
    Exec = ("C:\Windows\System32\route.exe" & " " & "ADD " & Text1 & " " & " MASK 255.255.255.255 192.168.1.1")
    txt_resultado.Text = ejecutar_Dos(Trim(Exec))
   

End Sub


Function ejecutar_Dos(Comando As String) As String
    Dim oShell As WshShell
    Dim oExec As WshExec
    Dim ret As String
     
    Set oShell = New WshShell
    DoEvents
     
    ' ejecutar el comando
    Set oExec = oShell.Exec("%comspec% /c " & Comando)
    ret = oExec.StdOut.ReadAll()
       
    ' retornar la salida y devolverla a la función
    ejecutar_Dos = ret ' Replace(ret, Chr(10), vbNewLine)
     
    DoEvents
    Me.SetFocus
End Function

el code de ejemplo va bien, con dir, ping, route

al poner por ejemplo, fastboot devices, el code arroja el dispositivo conectado, pero por ejemplo, al hacer fastboot getvar all, que me daría toda la info del movil, no arroja resultado...

alguna idea que puede ser?

algún code funcional?
gracias

Debes usar pipes.

El codigo si no te funciona te puede guiar, lo que hace es crear una instancia del shell y redirecciona la salida a una cadena ya despues puedes pasar esa salida a tu textbox.

Código
