Hi Sabine, Sean,

PLEASE NO WinExec, this is long deprecated and only for 16bit compatibility
see http://msdn.microsoft.com/en-us/library/windows/desktop/ms687393(v=vs.85).aspx

As you see on MSDN CreateProcess() API should be used.

If you are on Pharo 3.0 look at my "OS-Windows" project loadable from the config
browser.

You will find the class WinProcess with methods like #createProcess: (nonblocking)
and #createAndWaitForProcess: (blocking) there. It already uses CreateProcess API.

With the package you can for instance run the command processor:

WinProcess createAndWaitForProcess: 'cmd.exe'

You also have access to the environment like

WinEnvironment getEnvironmentVariable: 'PATH'.

See the documentation at http://smalltalkhub.com/#!/~OS/OS-Windows for more examples.

Bye
T.

Ha ha, yes Torsten. I couldn't get create process to work so I cheated ;) it works and takes only two parameters. This is exciting that you've already wrapped that stuff! I had no idea, there's probably so many great things out there. We could really use a PharoMap... I will take a look at your project. Maybe something could be integrated with NB core. Executing an external command on all the common platforms is a good demonstration of NB

Cheers,

Re: command line command from pharo image

Hi Torsten, Sean,

http://smalltalkhub.com/#!/~OS/OS-Windows
looks great.

I have not found a solution yet to send a call to OS from pharo (I develop with mac since a few weeks now and deployment is currently windows) and I am thinking about moving to Pharo 3.0 for further development due to the OS call problem.

Do you think, Pharo 3.0 is ready to use it for development or should I wait and look for another solution?

Regards
Sabine

Hi,

Pharo2 doesn't work for you?

I tried both Pharo2 and 3.

In
Pharo2.0
Latest update: #20593

with latest stable OSProcess loaded form ConfigurationManager

I can execute
OSProcess command:'notepad.exe'

without problems.

But only as long as the command can be found otherwise ExternalWindowsOSProcess tries to write
that error message to ExternalWindowsOSProcess>>initialStdErr.

And this does not work. (And it doesn't work in Pharo3)
(bug StdErr not working on Windows https://pharo.fogbugz.com/default.asp?11615)

Re: command line command from pharo image

Nicolai,

thank you very much for clarification. Indeed: there was a silly error in my command when copying it from Mac to windows (path) and the notepad test worked. So the problem is solved for me. I can call from Mac OS and from Windows and I am happy:-)

Regards

Sabine
