I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box.
How do I configure the scanner and my application so that my app can process the barcode data directly? That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPress event…

This one's got me stumped.
Whenever the system is asleep for a long time, e.g overnight, the LAN driver reports error code 43 ("a problem") and turns itself off.
This has being going on for months, but I never caught the problem until now. The owner merely shuttles back to a restore point I set her when the machine worked.

When making games for windows 7 phone will there be separate places for XNA based games and silverlight games? I'm curious how this will work.
Are all XNA based games going to work out of box? How would someone differentiate an app developed specifically for phone vs just a port?
I recently moved my app to a new server - the app is written in c# against the 3.5 framework. The hardware is faster but the OS is the same (Win Server 2003). No new software is running. On the prior hardware the app would run for months with no problems. Now, in this new install, I get the following error after about 3 days,…

My problem is that i have to send a packet to a shutdown system using UDP protocol.

I need to write a firefox extension that creates a server socket (I think that's what it's called) and returns the browser's current url when a client application (running on the same computer) sends it a request. The thing is that I have no Java/Javascript background at all and I'm pressed for…
I need to redirect all the requests from
localhost:8080/app1/ to localhost/app1.
which is the best way to do it.
The only requirement is that the user must never be aware that he is accessing the application at port 80. i guess I need to set up Apache HTTPD proxying - I'm just not sure…
