  - by Jon

  Has anyone used javascript/ajax to take data from one form field and put it into another? I'm trying to create a form that when one text input is filled out a second is auto-populated with the first letter of the word that is in the first text input. I'm thinking I can limit the second text input to one character to help get the desired result, but I'm not having luck finding the javascript to get the second text input to auto-populate from the first.

  I feel a little stupid for having to ask this… But I can't seem find it documented anywhere. If I've got a Model with FileField, how can I stuff an uploaded FILE into that FileField?

• atheros wireless device driver

  - by Rolo Susie

  I got a new laptop recently, and have been having trouble with it dropping wifi since I got it, the card is Qualcomm Atheros ar9485wb-eg. I've updated to the latest available drivers, currently 10.0.0.263, and tried other suggestions on the lenovo website, including uninstalling the driver and letting it install again. One thing I've noticed is when I look at the troubleshooting log, it gives the device driver number as 10.0.0.209. Does this mean the update isn't applying properly? Any help appreciated, Thanks

• C++ book for a c# developer

  - by Eldila

  I am a c# developer which finds himself having to relearn c++. The last time I programmed in c++ was in school and am looking for good books as a refresher. I want something that assumes previous programming exposure and gets straight to the point. Is there a book similar to K&R for c++? I know the language is bloated so a book that covers a subset of c++ would be ideal.
