• Changing keyboard layout on application focus

  - by Anonymous Coward

  Hi Everyone As everybody knows the en-US Keyboard-layout is the best one for programming. So I'd like to use it in my IDEs. But since I live in a non-en-US country I need the de-CH layout for all other applications. Now I wonder if it is possible to set the layout depending to which application currently has the focus. If that is possible, can a human brain adapt to such a behaviour or is it just confusing? cheers, AC

• Unable to display google maps in a dojo layout

  - by Jens

  Dear All, I am a real newbie in programming and now I have to combine Google Maps and Dojo. Both alone are fine but when I try to implement a Google Map into a Dojo content pane which is embedded in a border-container it simply does not work. I think there is a problem with the naming of the divs but perhaps there is something else to take care of? Could someone post the simplest possible solution? many thanks

• Debug assertion does not prompt in IIS 7

  - by Shugi

  Hi, since moving to Windows 7 (IIS 7.5), the debug assertions do not prompt a pop up dialog anymore. I have tested this in a separate project, and noticed that they do work when using the integrated Visual Studio Developer server (Cassini) but they do not work when using IIS Web Server. This is a big issue for us since we are counting on debug assertions to identify potential programming errors, so any help would be appreciated. Thanks. Eyal.

• How to communicate with a USB device under Windows and Java?

  - by Gili

  I'd like to communicate with a USB device under Windows and Java but I can't find a good library to do so. I don't want the user to have to install any extra hardware or device drivers to make this work. That is, I want to be able to interact with USB just like other Windows applications do. I am familiar with jUSB and JSR 80 but both seem to be dead projects (at least for Windows).

• lock-free memory reclamation with 64bit pointers

  - by JDonner

  Herlihy and Shavit's book (The Art of Multiprocessor Programming) solution to memory reclamation uses Java's AtomicStampedReference<T>;. To write one in C++ for the x86_64 I imagine requires at least a 12 byte swap operation - 8 for a 64bit pointer and 4 for the int. Is there x86 hardware support for this and if not, any pointers on how to do wait-free memory reclamation without it?
