I am not sure I completely understand what your doing but if you are starting a stand alone app running in the
app tray etc and you what to send it messages via stdin and std out. Ussually it is a pipe of some kind often beloning to
the task that started the app. Hope this helps.

You may want to use names pipes for a know endpoint

when you launch an app from the command line 

echo "hello" |  myapp
or
echo "hello" > 

the shell takes care of the creation of the pipes used to map the input and outputs to the stdin and stdout of the
the starting task my own the pipe.

Rather named pipes:
examples:
the recieving task
Static myinput As File

Public Sub Form_Open()

    Dim buffer As String

    myinput = Open Pipe "/tmp/mydesk" For Read Watch
    TextBox1.text = Application.id & " " & Application.name
    Print "pipe is open"; myinput

End

Public Sub file_read()

    Dim value As String

    Print "got message"

    While Lof(Last)
        value = Read #Last, Lof(Last)
        FMain.textbox2.text = value
    Wend

End


Public Sub Form_Close()

    Print "close the input file"
    Close #myinput

End

the sending task:
Public Sub Main()

    Dim sendto As String = "/tmp/mydesk"
    Dim myoutput As File
    Dim counter As Integer = 0

    myoutput = Open Pipe "/tmp/mydesk" For Write

    While True
        Write #myoutput, "please pay attention - " & counter
        Print " Sent message"
        Wait 2
        If counter = 100 Then
            Break
        Endif
        Inc counter
    Wend

    Close myoutput

End
