Raise alert

How would you raise an alert from a VB program that a Batch file program can obtain?

A batch file executes a VB pgm and depending on user response, the VB pgm needs to tell batch pgm to "go" or "stop". Aside from writing to a msg/flag file, is there some slick way (API, etc.) to raise an alert or set a condition code that the batch file can easily obtain? An example if you've got it.

Thanks

Declare this
Private Declare Sub ExitProcess Lib "kernel32" (ByVal uExitCode As Long)

Then to pass the value to the batch file in your program use
ExitProcess 1&
In this case it passes a 1
To pass a 100
ExitProcess 100&

Do you know how the batch file program would obtain this exitprocess value?

Let's say you want your program to return 2 values 100 & 50
100 is your go 50 is our quit. In your batch file do the following:
@echo off
start /w yourprogram.exe
if errorlevel 100 goto 100
if errorlevel 50 goto done
:100
your code that you want to execute for the go
goto done
:done
exit
