• How do you change the colours used in the annotate bar in Visual Studio 2008?

  - by Luke Bennett

  I am using a custom colour scheme in Visual Studio 2008. The annotate bar (that shows who checked each block of code in and when) is rendering in some illegible colours. I can't identify which colours these are within the relevant Options dialog so I cannot change them to something clearer. Does anybody know how to change these colours?

• Preferred Options for Webservice to Android

  - by Tim Almond

  I need to get an Android app to interface with an XML webservice (it's really just a request which returns XML), but as the data is large and includes some things I don't need (like a huge description block), I was thinking of transforming it via a server into a format that would be good for Android, and also to be reduced considering it will be used in a low bandwidth area. Does anyone have any suggestions for a good lightweight protocol? I'm especially thinking about libraries for Android that already exist for say REST or even delimited data.

  - by Ferol

  Good day, colleagues! Tell me please, how to make a dynamic xpath-parsing: for example, instead of writing $domXPath-query('//[(@id = "article-id-18")]'); - write something like that $domXPath-query('//[(@id = "article-id-*")]');, because in my case, the site's script generate (every time) a new id for block, that contains article's text?

• The simplest concurrency pattern

  - by Ilya Kogan

  Please, would you help me in reminding me of one of the simplest parallel programming techniques. How do I do the following in C#: Initial state: semaphore counter = 0 Thread 1: // Block until semaphore is signalled semaphore.Wait(); // wait until semaphore counter is 1 Thread 2: // Allow thread 1 to run: semaphore.Signal(); // increments from 0 to 1 It's not a mutex because there is no critical section, or rather you can say there is an infinite critical section.

• Visual Studio line deletion

  - by Sean

  Is there any way in Visual Studio 2003 that I can delete a line without it being copied into the clipboard? There are instances when I want to copy the first line of a block of text and then delete the following n lines but this then puts the last line I deleted into the clipboard, which is very annoying. I have come from a brief keymap background and I could easily do this with Alt-D. And while I'm on the subject, why on earth have MS stopped supporting the brief keymap?

• Android TimePicker hour field disappears after orientation change

  - by sosiouxme

  I am using a TimePicker under API 1.5 and when the orientation is changed on my device (a stock G1 running 1.6 - though NOT on the 1.5/1.6 emulator), the hour field goes blank. It still remembers the hour, it just doesn't show it. Is there any workaround for this? The same problem was described by someone else here: http://groups.google.com/group/android-beginners/browse_thread/thread/b4288004021b876/de5899a2bb291ab5 Nothing helpful was forthcoming - can StackOverflow do better?

  I'm planning on doing a application for Android 2.1 that changes song every minute (through what I hope exists in Android, "next track") for the application using the audio device atm. So if I have Spotify (http://www.spotify.com) running in background already, playing music, can I through my program change to the next track? Let me know if I was unclear about anything. Thanks in advance!

  If I have the following block of code in a method (using .NET 4 and the Task Parallel Library): var task = new Task(() => DoSomethingLongRunning()); task.Start(); and the method returns, will that task go out of scope and be garbage collected, or will it run to completion? I haven't noticed any issues with GCing, but want to make sure I'm not setting myself up for a race condition with the GC.
