Re: %errorlevel% and run/exec command

Having to code around error levels is like shooting paint balls against a moving target..

It is the 'modern' computer 'pulling' methodology, called "asking for comment"..

The target will swipe them away and know you better next time, posts to the net.

A decent exe is meant to accept and return anything from 0-9 and A-Z.

That is original switches aka "/reinstall" for the literate.

You were doing a really great job, Mr. Windows.

Hi,

I have a simple DOS batch which install some patches and process

set Install_RC= %errorlevel%

Now, I'd like to simply write the same thing in wsh and I have tried
different approach using the reference:

reading STDOUT and so on... but I'm not retrieving %errorlevel% value.
my perception is that when use RUN method, you can control the process
execution really have dependencies but you can get the output of the
execution and we use EXEC you can get the output but where
syncronization the child process.

Thanks for any example as I'm sure that my previous is not accurate.

The WshScriptExec object returned by the WshShell.Exec method has an...

By way of further explanation to the OP, it should be recognized that ERRORLEVEL is one of seven "dynamic environment variables" that are "computed dynamically each time the value of the variable is expanded" (see the "set /?" command for info). This is a function of CMD.EXE command extensions, which are likely not involved when a WSH script launches an executable.
