Hi, thanks so much for your promptly support. It worked!!!.
I was doing
FileDirectory deleteFileNamed: 'c:\temp\prueba.txt'. and get an error.
But then I tryied
FileDirectory default deleteFileNamed: 'c:\temp\prueba.txt'. and it worked.
Sorry I missed include default
Again, thank so much.
This is the first time I wrote.
I am trying to use Seaside to work with Web Services that provide a Xerox Multifunction Device. I will tell you how everything is going on, If there is anay doubt I will tell you.
Best Regards
Marcos.

Hi,
I'm developing a mod for Scratch that will allow controlling an educational robot via Bluetooth. I'm using SerialPort2 class that is included in Scratch plugin and allows opening ports by name. Everything works fine BUT, when I send commands in a loop, and the connection is lost (i.e. the robot was powered off), the VM freezes. I tried forking the port nextPutAll like that:
timer := Delay forMilliseconds: 1000. port := SerialPort2 new. port openPortNamed:'COM14' baud:57600. process := [port nextPutAll:'test'. Transcript show:'port'.] forkAt: 1. [timer wait. Transcript show:'delay'. process terminate.] forkAt: 7.
but with no result. Is there any way to write to a serial port with timeout?

I can't help you with the SerialPort issue, but the process priorities 1 and 7 are definitely bad. Since the idle process uses priority 10, your processes will never run. Try using something between 11 and 39, or use the named priorities: Processor userBackgroundPriority Processor systemBackgroundPriority

Well, at first I tried using larger numbers, but it seems, that my VM has maximum priority equal to 8. Processor userBackgroundPriority prints 3 and Processor userInterruptPriority prints 5.

hi Marcos,
Welcome. I hope you are having fun with it. First, I've updated the subject to be more specific. That makes it easier for us to track. Hope that is okay. A few queries then to narrow down the scope of your query..
You say 'windows' but use all lower case. Do you mean 'Windows' as in Microsoft Windows? Also which version?
By 'system directory', do you mean 'C:\Windows\System' or 'C:\Windows\System32' or some other protected directory?
You imply that you already know how to delete a file outside the system directory. What is the code you used that was successful for that, which fails with a system directory?
What things have you tried already?
- Can you delete the required file outside of Seaside, just Pharo 1.3 ?
- Can you delete the required file outside of Pharo 1.3, from Windows
Explorer, and from the command-line ?
btw, You may find the following of interest... http://www.catb.org/esr/faqs/smart-questions.html
I'm not an expert, but with answers to those questions I hope I'll be able to help you.
cheers -ben
