4,641,580 | 4,641,581 | Python Regular expression to end of line | <p>Bit frustrated that I can't work this out but I want to define a regular expression that selects an unknown amount of words (some spaced, some incorporating numbers, some underscored).</p>
<p>When I say 'unknown amount of words' I'm happy to limit it to 10, if that's more realistic.
Basically I'm scanning file names and don't suspect there are any longer than 10 words, but it would be nice not to have to set a limit.</p>
<p>The best I have so far is:</p>
<pre><code>tc = re.findall(r'FROM CLIP NAME:\s\s(\w*\s*\w*\s*\w*\s*\w*\s*\w*\s*\w*\s*\w*\s*\w*\s*\w*\s*\w*)', text)
</code></pre>
<p>Where 'FROM CLIP NAME:\s\s' will be at the beginning of each line.</p>
<p>My attempt above is a complete fail as \s reads line breaks as well as spaces and so also grabs data from the next line.</p>

var myDrawer = function(myObjRef) {
this.myInternalObject = myObjectRef;

<p>[[EDIT - Adjusted Object Creation to Ensure 'this' is being mapped to myObject, not the global window object]]</p>

1,227,133 | 1,227,134 | Request for Advice c# Webplayer | <p>I am currently building an asp.net c# Website for a client of mine to promote their band, on there they would like to have a Webplayer which continues to play music as people are browsing the site. The player is located on the Master page so it is included on every site, but it stops playing every time the site does a postback or refreshes in any way.</p>
<p>I think it is possible to achive this using Iframes or Ajax, although i dont have alot of knowledge in either.The site is only about 6 pages with mainly static information on there, so the only postbacks/refreshes will be done by using the navigation menu to load each page.</p>
<p>My question to you is:</p>
<p>how can I achive this?</p>
<p>what would be the easiest method and what are the pros and cons?</p>
<p>are there any other/better ways of achiving this other than using Iframes or Ajax?</p>
<p>I can provide some code if needed.</p>
<p>Thanks,</p>

<p>The compiler's message, relating to the row with the comment, is </p>
<blockquote>

<p>Now, I perfectly well understand that any field or method can't be placed out there "in the open". It needs to be part of a class, and inside one. BUT IT IS NOT A FIELD OR A METHOD THAT I AM CODING, IT IS A CLASS IN ITSELF. None of the other classes, above in the code, gave this problem. It started when I wrote the very last and as yet empty class.</p>
<p>Is Visual Studio's compiler working right? Or what is it in 40-odd lines that I am not seeing? Very grateful for comments that could help.</p>

<p>Here is my question. I have an app that is very small; however it pulls data from the webservice/MySql database online. It is supposed to only pull data on first open. Or, if the user selects update data from a menu. I do not have an exit button in the app, However I thought that if the user would back completely out of the app, this would be the same as an EXIT. </p>
<p>After backing out of the app, I can still see the app in Setting>Applications>Running Services. It says "1 process and 1 service". In Manage Applicaions, it says that the app has been running for 36 hours.
Is this okay? I do not want users to think my app is using their battery.
On a separate note, I do not see an additional updating (pull from webservice) after backing out. But if I install the app on my galaxy Tablet 10.1 running Android 3.1, I do see an occasional update from the webservice. </p>
<p>Anyone have some advice for me?</p>

<p>For each id there are sometimes different values. I want to count how many entrances there are for each id, the average and the sum of the values for each id so the outcome would be something like this:</p>

<p>I thouht it would be best to first make a dictionary where I count each entry, but got stuck after that, not knowing if it is best to have the value of the dictionary as an array (with the cnt, sum and av) and by then using the range of the Cnt to calculate, but could not think of ways to do that! This is how far I got:</p>
<pre><code>idDict = {}
for line in file:
line = line.rstrip()
f = line.split()
id = f[0]
idDict[id] = idDict.get(id, 0) + 1
</code></pre>
<p>But if I have already created the dictionary here with the cnt, I dont know how to iterate over each id to do the sum and av calculations :( </p>

<p>How could I do it?
All the tutorials I've seen so far where retrieving data from resources.</p>
<p>EDIT :</p>
<p>Let's be a bit more precise:</p>
<p>My Activity has a ListView on the left part. When you click on it, the idea is to load a Fragment on the right part.</p>
<p>When I enter this Activity, an Object "Category" is given through the Intent. This Object contains a List of other Objects "Questions" (which contains a List of String). These "Questions" objects are displayed on the ListView.
When I click on one item from the ListView, I want to display the List of String into the Fragment (into a ListView).</p>
<p>To do that, I call the setContentView() from my Activity with a layout. In this layout is defined the Fragment with the correct class to call.
When I call this setContentView(), the onCreateView() of my Fragment is called but at this time, the getArguments() returns null.</p>
<p>How could I manage to have it filled before the call of onCreateView() ?

BindingFlags.NonPublic | BindingFlags.Instance).MakeGenericMethod(commandType);
var actionType = typeof(Action<>).MakeGenericType(commandType);
var @delegate = Delegate.CreateDelegate(actionType, this, genericExecuteAction);
var actionDelegate = (Action<DomainCommandBase>)@delegate;
messageBus.Register(actionDelegate);
</code></pre>
<p>The problem is i need to cast it so that i can pass it to this method.
You see?
Behind the mesasge bus we are using is using RX and unfortunately all the methods there use generics, there a now non-generic-overloads.</p>

1,856,522 | 1,856,523 | using libusb header file | <p>I need to communicate with USB port by C++. so I searched the web and found a comppresd (.rar) file. Its name is <code>usblib-1.0.9.tar.bz2</code>. I extracted it and it contains several files and folders and some of them are header files (*.h). I think my necessary file is one of them that its name is <code>libusb.h</code>. </p>
<p>Moreover in this comppresed file there are some example programs to communicate via USB. I copied one of them to a C++ empty program for testing. This program uses libusb header file as one of library. </p>
<p>I added libusb.h to this program (right click on Header Files in solution explorer and choose <code>add > existing item</code> then browse <code>libusb.h</code>), but this library (<code>libusb.h</code>) is still unspecified (<code>#include <libusb.h></code> is unspecified ) and I can't debug this example program. Do I need to do another action to add this new library (<code>libusb.h</code>) to use in this program?</p>

function theme_setup() {
add_image_size( 'theme-custom-size', 329, 118, true );

<p>which is fine for the featured image, I just call</p>

I have no experience with audio in Android, however several sources suggest that to simply play a clip, I need only do the following - </p>
<ul>
<li>Put the audio file in /res/raw </li>
</ul>
<p>I did this, I had to create a /raw folder within /res/ - the file is named menuclick.wav (so seems to meet the guidelines for a-z0-0_ filenames) </p>
<ul>
<li><p>Create a MediaPlayer object </p>
<p>MediaPlayer mediaplayer;
mediaplayer.create(getApplicationContext(), R.raw.menuclick); </p></li>
<li><p>Prepare the player for playback (*within a try - catch block) </p>

<li><p>Play the file </p>
<p>mediaplayer.start(); </p></li>

359,065 | 359,066 | Where should I display or store data that is imported from a file? | <p>When I do an import of data from a file, such as csv or text file, I would like to display on a summary page （table view) about what is going to be imported to the database, and user can select or deselect what will be imported into the database. I would like to find out what is the best way of temporary storing these data to be displayed onto the summary page?</p>
<p>To give a clearer understanding about what i am talking about, for example: </p>
<ul>
<li>I have a csv file that holds a list of products. </li>
<li>I would do an importation to read the csv file and display onto a summary page with
table view and checkboxes to select/deselect some of the data.</li>
<li>After the selection, I would click the confirm button to store those checked data</li>
</ul>
<p>So between the process of getting the csv data to the summary page for display, where should I store the data, in the database as a tbl_temp data and clean off when done, or just read directly from the csv file?</p>
<p>Thanks.</p>
