I have an MSI-packaged application that is being deployed via Group Policy Objects (GPO) from a Windows 2003 Domain Server to all the XP client machines in the network.

How do I preserve variables in batch scripts when set in "for" loops?

I need to set my classpath using all of the jars in a particular directory. Bash does it as follows: CP_DELIMITER=; for j in "$MY_HOME/javalib/*.jar"; do if [ "$CP" ]; then CP="$CP$CP_DELIMITER$j" else CP="$j" fi done But "for" works differently in DOS, and essentially sends the command to the shell, but ...

The role of scripting languages in game Programming

So I've been running into a debate at work about what the proper role of a scripting language is in game development. As far as I can tell there are two schools of thought on this: 1) The scripting language is powerful and full featured. Large portions of game code are written in the language and code is only moved into C++ when perfo...

Is there an equivalent of Don Libes's *expect* tool for scripting interaction with web pages?

In the bad old days of interactive console applications, Don Libes created a tool called Expect, which enabled you to write Tcl scripts that interacted with these applications, much as a user would.
