4,365,035 | 4,365,036 | Using static variables to store user info on Android | <p>I'm making an android app which has to frequently call some .net web services using the kSoap2 library. The user has to log in each time the app is launched (a decision that is out of my hands). I have one class which calls the web services. Each web service requires a username, a password and one other data string to access it. When the user successfully logs in I store the correct username, password and other piece of data in 3 private static variables inside the web services class, to use when I need to call other web services.</p>

<p><strong>EDIT:</strong>
My solution is good enough for my case where the problematic characters are extras that I can discard safely. They are the result of the fact that I cannot control all clients that connect to my server and some clients seem to be sharing a common socket library or something that ads the extra characters.
Normal they should not be there as the entire transmission should only contain UTF-8.</p>
<p>I would however be more then happy to chose any answer that gives me a general solution that can convert the string to UTF-8 not just some copy pasted answers from the first Google result like some people just did to get some extra experience. </p>
<p>I don't care if I convert or remove the extra characters the data sent is something to be analyzed by humans so it does not matter, but a real solution does.</p>

I have taken my code which works and now put it into a static library for another program to use. In my library I am using another static library which I don't want the people who will be using my API to know. Since, I want to hide that information from them I can't tell them to install the other static library.
Anyway, I used the command line Lib.exe to extract and create a smaller lib file of just the obj's I used. However, I get a bunch of "LNK4006 :second definition ignored" linker warnings for each obj I use followed by "LNK4221 no public symbols found;archive member will be inaccessible".</p>
<p>I am doing this work in vs2008 and I am not sure what I am doing wrong.
I am using the #pragma comment line in my .cpp file
I have also modified the librarian to add my smaller .lib along with its location.
my code simply makes calls to a couple functions which it should be able to get from those Obj file in the smaller lib.
All my functions are implemented in .cpp file and my header just have the includes of the third party header files and come standard c++ header files. nothing fancy. I have actually no function definitions in there atm. I was going to put the API definition in there and implement that in the .cpp for this static lib that i was going to make. However, I just wanted to build my code before I added more to it. s</p>

2,786,286 | 2,786,287 | logical problem in mailing a HTML File | <p>I want to send and HTML file using JSP. But the problem is..<br>
1) When we develop any HTML File we mention some CSS and JavaScript files.<br>
2) So, when i am sending the file, it is missing all the format what i defined in other page(in form of CSS and javascript).<br>
3) So, now I want to implement such a logic by which, it can read all the CSS and JavaScript file and send it with mail together.<br>
4) With same file position and structure. That is, i want to maintain the directory position of CSS and JavaScript.<br>
5) It is possible, but for this i would have to send the CSS/JS file also.That thing i don't want to do explicitly. </p>
<p>Some possible solution what i thought before asking here.......<br>
a) I can add all CSS/JS contents in HTML file, so that it will go with html file at the single time.<br>
b) But it is ok with one or two file. But if I have plenty of files in my website then I would have to copy this content in all file which i don't want.<br>
c) zip all the file together and mail it. But, it also i don't want. I want to mail only .HTML file.<br>
d) I can read HTML file and read the file which has included or added in HTML and mail it implicityly. but in this case, directory structure will not be mentened. </p>
<p>I know it is different type of question. I don't want the code. I just want the logic..<br>

4,232,977 | 4,232,978 | In Android is it possible to transfer ownership of a touch event? | <p>I am developing a modal movie player that changes mode based on gestures. At the moment the different modes are separated into individual ImageViews, since each mode's composition and interaction is distinct.</p>
<p>I am holding the views in a single ViewGroup. The ViewGroup will ensure that only one ImageView is visible at any time. The views will be togged via gestures.</p>
<p>One such gesture is a drag. Currently I am handling gestures within the ImageViews, and via callbacks triggering the ViewGroup to switch views.</p>
<p>I am having a problem with transfer of the move action from the current view to the switched view. The current view detects the move touch event, then triggers the switch. However, the new view does not see the remainder of the touch event.</p>
<p>My question is, is it possible to transfer ownership of a touch event from one view to another?</p>

98,240 | 98,241 | How to: Creat PHP link to KML element | <p>I wrote a lengthy KML file containing multiple Placemark tags -- each has the usual components: name, LookAt, styleURL, Point ... and so on. Now, I want to create links to each placemark from a PHP file. The following link in the PHP file opens the KML file in Google Earth, as expected:
(a href="http://www.galapagos.to/kmz/galapagos.kml") (my site name is galapagos.to and the parens are actually angle brakets)
Now, I add an placemark id to the above, as follows:
(a href="http://www.galapagos.to/kmz/galapagos.kml#Watson") (the "Watson" at the end is the ID of one of the Placemarks. When I click the link in the PHP file, the KML file again opens, but the #Watson at the end is ignored. So the big question -- Is there some way to get a KML file to go to the specified ID name, as is standard practice in HTML files?
Any suggestions?

9,452 | 9,453 | Are array/list lengths and string hashcodes memoized? | <p>Does anyone happen to know if, in .NET (4.0, if it matters), the Length property of an array, or the Count property of a <code>List<T></code> is stored after it's been calculated, until the array/list is changed?</p>
<p>I ask because a record linkage program I'm working on is already horrifically complex enough as it is, and I'd rather not add another O(n) on top of things if I can help it.</p>
<p>Along similar lines, is the hashcode of an instantiated System.String memoized? Looking at it through the debugger, I can see that <code>List<T></code> has a private _size member that <em>could</em> be where Count gets its value, but I see nothing for int[] or string indicating that they store it anywhere.</p>
<p>I can see the size vs. speed tradeoff, but can anyone tell me for sure if there are backing fields that hold these? For example, since in C#, strings are immutable, wouldn't it make sense to calculate the hashcode the first time <code>GetHashCode</code> is called, and just store it for every later use?</p>

2,479,531 | 2,479,532 | Android library project - how to get context? | <p>I have been happily refactoring code from different versions of the same app (paid/free) into Android library projects so that the actual apps can simply customize the library and reduce code duplication.</p>
<p>One thing I'm started to wonder is what getApplicationContext() inside the library code means? Is is the same ApplicationContext as one would get from the child apps? What happens when I access SharedPreferences from a library project's getApplicationContext() instead of the original app's ApplicationContext()? Will the SharedPreferences file be same or different?</p>
<p>What if I had used the activity to access SharedPreferences? Does it matter that the activity is now a library activity and not the original app? Is the SharedPreferences the same?</p>

<pre><code>+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |

<p>I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.</p>
<p>So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.</p>
<p>So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.</p>
