I&#39;m using the `get_browser()` function in an attempt to warn people that their browser doesn&#39;t support Javascript. Actually I&#39;m using it to tell them they can use certain parts of a web application I&#39;m building. I&#39;ve decided to properly use Javascript because I&#39;m tired of listening to developers that are scared of using it and I&#39;ve seen some great potential in the language. I digress, here is the error.

Now I&#39;d imagine this means I need somthing set it the php.ini. Can someone give me some direction on this one?

I&#39;m writing a property list to be in the resources bundle of my application. An `NSString` object in the plist needs to have line-breaks in it. I tried `\n`, but that doesn&#39;t work. What do I do to have newlines in my string in the plist?

Thanks.

A lot of open source libraries that aid in Android application development have sprung up with time. IMO looking at source code of good projects helps learn the system better, faster and not to mention reduces development time. Is there a recommended list of such projects or if not, can we build such a list? I think it will really be useful to other developers.

Thanks.

**Hi All,**

I have 2 questions regarding a ListView in Android:

01. How can I **get** the color of the listview&#39;s focused row ?
I tried to use the **ListView.getSelector()** method, which according to its documentation should give me what I&#39;m looking for, but it&#39;s giving me a Drawable object which I don&#39;t know how to retrieve the color from (if possible...).

02. How can I **set** the color of the listview&#39;s focused row ?
Here I tried to use the **setSelector()** method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...

Thanks!

My WakeLock isn&#39;t keeping my device awake.

In `OnCreate()` I&#39;ve got:

    PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK | PowerManager.ON_AFTER_RELEASE, &quot;My Tag&quot;);
    mWakeLock.acquire();

then:

    new CountDownTimer(1320000, 200) {
    
        public void onTick(long millisUntilFinished) {
            // I update a progress bar here.                            	         
        }

        public void onFinish() {
            // I finish updating the progress bar.
            mWakeLock.release();
        }
    }.start();

The screen turns off before the timer finishes, how can I make the screen stay visible?

`mWakeLock` is a field previously declared like so:

    private PowerManager.WakeLock mWakeLock;



My device uses Android 1.6.  I would really appreciate any help to resolve this.

I have two different activities. The first launches the second one. In the second activity, I call `System.exit(0)` in order to force the application to close, but the first activity is automatically displayed instead of the application returning to the home screen. How can I avoid this, and get the application to return to the home screen?

I&#39;m really tired looking for a solution for vertical and horizontal Scrollview.

I read that there are not any views/layouts in the framework which implement this feature, but I need something like this:

I need to define a layout within other, the child layout must implement scrolling vertical/horizontal for moving.

Initially implemented a code that moved the layout pixel by pixel, but I think that is not the right way.
I tried it with ScrollView and Horizontal ScrollView but nothing works like I want it to, because it only implements vertical or horizontal scrolling.

Canvas is not my solution because I need to attach listeners in someones child elements.

What can I do?

Just to ask if anyone knows of an **open source** alternative to RedGate&#39;s [Reflector][1]?  I&#39;m interested in checking out how a tool similar to Reflector actually works.  

Note, if you know of a free but **not** open source alternative to Reflector, you can answer the following related question:

 - [Something Better than .NET Reflector?][2]

**Summary - Updated 11th May 2011**

A quick round-up of the various open source projects and tools that have been suggested:

 1. [Common Compiler Infrastructure][3] (CCI)
 2. [Mono Cecil][4]
 3. [ILSpy][5]
 3. [dnSpy][14] (fork of ILSpy, project appears more active than original)
 4. [Dotnet IL Editor (DILE)][6] 
 5. [IL.View][8]
 6. [Monoflector][7] (&lt;a href=&quot;http://twitter.com/#!/jcdickinson/status/54874110811058176&quot;&gt;no longer active&lt;/a&gt; as of April 2011)

The following resources may also be of interest:

 - [TypeView.cs][9]
 - Jason Haley&#39;s notes on [disassembling .NET][10]
 - [Adrian Bank&#39;s][11] recent [blog post][12] summarising a number of Reflector alternatives, including several options not mentioned below.
 - Mark Lichtenberg&#39;s detailed [blog post][13] comparing several of the open source alternatives (DILE, ILSpy and Mono Cecil using MonoDevelop) to Reflector.

Open Source Alternatives to Reflector?

I&#39;ve finished reading the spring doc and the PetClinic sample project. Just like to see some bigger real world project that&#39;s done with Spring. Thanks.

Any open source Spring sample project that&#39;s bigger than PetClinic?

If we&#39;ve learned anything from HTML/CSS it&#39;s that, declarative languages (like XML) do a good job of describing User Interfaces because:

1. It&#39;s easy to build code preprocessors that can template the code effectively.
2. The code is in a well defined well structured (ideally) format so it&#39;s easy to parse.
3. The technology to effectively parse or crawl an XML based source file already exists.
4. The UIs scripted code becomes much simpler and easier to understand.
5. It simple enough that designers are able to design the interface themselves.
6. Programmers suck at creating UIs so it should be made easy enough for designers.

I recently took a look at the meat of a WPF application (ie. the XAML) and it looks surprisingly familiar to the declarative language style used in HTML.

The current state of desktop UI development is largely fractionalized, otherwise there wouldn&#39;t be so much duplicated effort in the domain of graphical user interface design (IE. GTK, XUL, Qt, Winforms, WPF, etc). 

[There are 45 GUI platforms for Python alone][1]

What are some Open Source GUI&#39;s that represent these characteristics:

 - standardized
 - platform independent
 - declarative markup language
 - language agnostic

WPF, or more specifically XAML seems like a pretty likely step in the right direction.

**Update:**
===========

Thanks a lot for the info, keep it comin&#39;. Here&#39;s are the options I&#39;ve gathered from the comments and answers.

**[GladeXML][2]**

 - Editor: [Glade Interface Designer][3]
 - OS Platforms: All
 - GUI Platform: [GTK+][4]
 - Languages: C (libglade), C++, C# (Glade#), Python, Ada, Pike, Perl, PHP, Eiffel, Ruby

**[XRC (XML Resource)][5]**

 - Editors: [wxGlade][6], [XRCed][7], [wxDesigner][8], [DialogBlocks][9] (non-free)
 - OS Platforms: All
 - GUI Platform: [wxWidgets][10]
 - Languages: C++, Python ([wxPython][11]), Perl ([wxPerl][12]), .NET ([wx.NET][13])

**XML based formats that are either not free, not cross-platform, or language specific**

**[XUL][14]**

 - Editor: Any basic text editor
 - OS Platforms: Any OS running a browser that supports XUL
 - GUI Platform: Gecko Engine?
 - Languages: C++, Python, Ruby as plugin languages not base languages

Note: I&#39;m not sure if XUL deserves mentioning in this list because it&#39;s less of a desktop GUI language and more of a make-webapps-run-on-the-desktop language. Plus, it requires a browser to run. IE, it&#39;s &#39;DHTML for the desktop.&#39; 

**[CookSwing][15]**

 - Editor: [Eclipse][16] via [WindowBuilder][17], [NetBeans 5.0][18] (non-free) via [Swing GUI Builder aka Matisse][19]
 - OS Platforms: All
 - GUI Platform: Java
 - Languages: Java only 

**[XAML (Moonlight)][20]**

 - Editor: [MonoDevelop][21]
 - OS Platforms: Linux and other Unix/X11 based OSes only
 - GUI Platforms: [GTK+][22]
 - Languages: .NET

*Note: XAML is not a pure Open Source format because Microsoft controls its terms of use including the right to change the terms at any time. Moonlight can not legally be made to run on Windows or Mac. In addition, the only platform that is exempt from legal action is Novell. [See this][23] for a full description of what I mean.
XAML is also not an ECMA standard like C#, Managed C++, and the CLR.* 

**Update: The question has been changed from &quot;Is there an Open source alternative to WPF? because the original question was wrong, and it sucked. The direction of this question has changed direction to match up to align with the new input. My apologies to the people who responded before it changed.**

What are the Open Source alternatives to WPF/XAML?

Is there any open source Javascript based PDF Viewer available? Any guide to developing this kind of script that renders PDF docs would be helpful.

Open Source Javascript PDF viewer

I have been reading through the backlog of answered questions on SO regarding &quot;How to promote an open source project&quot;. Not surprisingly, many of the answers pointed people to SoureForge/FreshMeat and other sites etc as well as blogging and whatnot. This started me thinking where is the best place to host a project and why?

As my first project is currently hosted on CodePlex, I started to wade through the Google search results to collect information on the pros/cons of each; however the comparisons that I found are rather dated (2+ years old). 

http://www.stum.de/2008/12/13/sourceforge-vs-codeplex/  
http://www.developmentnow.com/blog/2006/11/codeplex-vs-sourceforge/  
http://www.spacesocket.com/forum/thread-6654.html  
etc...

So the next question becomes &quot;Should I host my project on multiple sites&quot; to which the following post provides the expected answer (thankfully! as that would be a pain to maintain).

https://stackoverflow.com/questions/536528/hosting-an-open-source-project-at-several-sites

Based on the current state of various Open Source hosting sites such as CodePlex, GitHub, Google Code, SourceForge, etc, etc is there any notable pros/cons of one site over the other? i.e., should I stick with CodePlex or am I missing out by not using one of the alternatives? Will one bring about more traffic to a new and unknown project?

I plan on exploring each site in more detail to see what they all offer, but given the vast knowledge of the good folks on SO, figured I would start with this question first.

**UPDATED**

As per erjiang answer below... I am currently using Mercurial for version control, and I am open to anything other than TFS. Also, my current project is only me developing, but future projects may be collaborative so worth considering...
