Hi,

I want to know that how to return value(s) from vb.net while execute Batch file,

See my Example:
-----------------

@echo off
cls
echo started...

TestApps.exe "C:\Test\Test1.prj" "Test1.xml"

@if "%ERRORLEVEL%" == "0" goto good
@if "%ERRORLEVEL%" == "-1" goto fail

:fail
    echo Execution Failed
    echo return value = %ERRORLEVEL%
    goto end

:good
    echo Execution succeeded
    echo Return value = %ERRORLEVEL%
    goto end

:end

pause

1. The above code is working fine, because critical message return to the batch file (application will be closed automatically when TestApps.exe critical exception raised),
Ex:
i. Environment.ExitCode = 0
ii. Environment.ExitCode = -1
Note1: If application closed then only return error code to the batch file.

2. But I want to know that how to return warning message code. (In this time TestApps.exe will not be close, because it is warning message.
but I want to access warning message code in batch file without close application.
Note2: How to return value to batch file for each time getting warning message.
Give Idea.

Thanks in Advance.
