  • Getting specific values with regex

    - by David
    I need to knowingly isolate each row of the vCard and get its value. For instance, I want to get "5555" from X-CUSTOMFIELD. So far, my thoughts are: "X-CUSTOMFIELD;\d+" I have been looking at some tutorials and I am a little confused with what function to use? What would my regex above return? Would it give me the whole line or just the numerical part (5555)? I was thinking I i get the whole row, I can use substring to get the digits? BEGIN:VCARD VERSION:2.1 N:Last;First; FN:First Last TEL;HOME;VOICE:111111 TEL;MOBILE;VOICE:222222 X-CUSTOMFIELD;5555 END:VCARD

    - by Julien
    Hi all, I have a problem with a Javascript request to the Google Map Api Web Service : if I have the HTML file on my computer it works, but it doesn't work online. Here's the code : url = 'http://maps.google.com/maps/api/geocode/json?address=Senador+Francisco+Quindimil+Y+Carabobo+Por+Carabobo,Ciudad+Autonoma+de+Buenos+Aires,Argentina&sensor=false'; $.get(url, function(data) { $('#result').html(data); alert('Load was performed.'); }, 'text'); This sample is just supposed to load the "data" in the "result" element. When it is offline, the "data" has text, but not when it is online. Sample here : Online Web Service Test Could one of you guys help ? Thanks a lot !

  • C# Inherited member variables behaving undexpectedly

    - by Nilbert
    If I have a class like this: class A { public string fe = "A"; } And a class that inherits from it like so: class B : A { public string fe = "B"; } Visual C++ will tell me that B.fe hides A.fe so I should use the new keyword. So I change class B to look like: class B : A { public new string fe = "B"; } And then I have a function that takes an A (but, by virtue of inheritance, will also take a B) like this: class D { public static void blah(A anAObject) { Console.Writeline(A.fe); } } Even when I pass it an instance of a B object, which it will take without question, it will print "A"! Why is this, and how can I make it work how I want without setting the variable in the constructor?

  • Show/hide using jQuery cookies

    - by Dilwin
    So I've created a simple tip box that fades in on page load, with an option to close the box. I'm trying to make the box hidden if the visitor clicks the close link. I'm fairly new to cookies, so I'm probably doing it all wrong, but this is what I have: $('#close').click(function(e) { jQuery.cookie('tip', 'hide', cookieOpts); $(this).parent('div.tip').fadeOut(1000); e.preventDefault(); }); jQuery.cookie('tip', 'show', cookieOpts); $('.tip').delay(500).fadeIn(1000); var shouldShow = jQuery.cookie('tip') == 'show'; var cookieOpts = {expires: 7, path: '/'}; if( shouldShow ) { $('.tip').delay(500).fadeIn(1000); } else { $('.tip').css('display', 'none'); }

  • get all widgets inside an element

    - by peirix
    From the dojo documents on dijit.registry, I see the forEach method accepts a last parameter thisObject. But it doesn't way what that object is. Is it a dijit widget or a dojo object? I want to destroy all widgets inside an element (that will be replaced by AJAX) so they can be parsed again without conflicting id's. dijit.registry.forEach(function(w) { w.destroyRecursive(); }, dojo.byId("ajaxElement")); But this destroys ALL widgets on the page...

  • How to refresh site if $_SESSION variable has changed

    - by 4ndro1d
    I'm writing in my $_SESSION variable from a database, when i clicked a link. public function getProjectById($id){ $query="SELECT * FROM projects WHERE id=\"$id\""; $result=mysql_query($query); $num=mysql_numrows($result); while ($row = mysql_fetch_object($result)) { $_SESSION['projectid'] = $row->id; $_SESSION['projecttitle'] = $row->title; $_SESSION['projectinfo'] = $row->info; $_SESSION['projecttext'] = $row->text; $_SESSION['projectcategory'] = $row->category; } } Now my variable is overwritten and I want to show these variables in my index.php like this: <div id="textContent"> <?php if(isset($_SESSION['projecttext']) && !empty($_SESSION['projecttext'])) { echo $_SESSION['projecttext']; }else { echo 'No text'; } ?></div> But of course, my page will not refresh automatically. How can I do that?

  • Linq To SQL: Retain list order when using .Contains

    - by rockinthesixstring
    I'm using Lucene.net to build a MyListOfIds As List(Of Integer) which I then pass on to my Linq service. I then search the database as follows Return _EventRepository.Read().Where(Function(e) MyListOfIds.Contains(e.ID)).ToList Now I know that Lucene is already ordering MyListOfIds based on the weight it gave each term. What sucks is that Linq is losing that order in it's SQL search. My Question: How can I retain that sort order when building my Lambda expression? I tried using LINQPad to see how the query is being built, but because I had to declare a variable LINQPad didn't show me the resultant SQL :-( Here's what I tried in LINQPad Dim i As New List(Of Integer) i.Add(1) i.Add(100) i.Add(15) i.Add(3) i.Add(123) Dim r = (From e In Events Where i.Contains(e.ID) Select e) note: my example is in VB.NET, but I don't mind if responses are in C#

  • How fast are App Engine db.get(keys) and A.all(keys_only=True).filter('b =', b).fetch(1000)?

    - by Liron Shapira
    A db.get() of 50 keys seems to take me 5-6 seconds. Is that normal? What is the time a function of? I also did a A.all(keys_only=True).filter('b =', b).fetch(1000) where A.b is a ReferenceProperty. I did 50 such round trips to the datastore, with different values of b, and the total time was only 3-4 seconds. How is this possible? db.get() is done in parallel, with only one trip to the datastore, and I would think that looking up an entity by key is a faster operation than fetch.

  • C# & C++, runtime error when call C++ dll from C#

    - by 5YrsLaterDBA
    I have written a C++ wrapper DLL for C# to call. The DLL was tested and worked fine with my C++ test program. now integrated with C#, I got runtime error and crashed. Cannot use debugger to see more details. The C++ side has only one method: #ifdef DLLWRAPPERWIN32_EXPORTS #define DLLWRAPPERWIN32_API __declspec(dllexport) #else #define DLLWRAPPERWIN32_API __declspec(dllimport) #endif #include "NB_DPSM.h" extern "C" { DLLWRAPPERWIN32_API int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, string& message) ; } in the C# side, there is a definition, [DllImport("..\\..\\thirdParty\\cogs\\DLLWrapperWin32.dll")] public static extern int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, ref string message); and a call: string msg = ""; int returnVal = WriteGenbenchDataWrapper(rawDataFileName, parameterFileName, outputBaseName, logFileName, ref msg); I guess there must be something wrong with the last parameter of the function. string& in C++ should be ref string in C#?

  • Pass data in np.dnarray to Highcharts

    - by F.N.B
    I'm working with python 2.7, jinja2, flask and Highcharts. I create two numpy array (x1 and x2, type = numpy.dnarray) and I pass to Highcharts. My problems is, Highcharts don't recognize the commas in the vector. This is my jinja2 code: <script> $(function () { $('#container').highcharts({ series: [{ name: 'Tokyo', data: {{ x1 }} }, { name: 'London', data: {{ x2 }} }] }); }); And this is the error that I look with network chrome dev tools: series: [{ name: 'Tokyo', data: [1 4 5 2 3] }, { name: 'London', data: [3 6 7 4 1] }] I need change the numpy array to python list to pass to Highcharts or there is a better way to do?? Thanks

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • How to make windows media player go to previous song in playlist?

    - by SadSido
    Hi, everyone! I am writing a simple Windows app in c++, that will be able to send commands to windows media player. My problem is that I want my app to move to the previous song in the playlist. IWMPControls::previous() seems to do the job, but its behavior differs from what is written in msdn. In fact this function rewinds current media to the beginning and then (if current position is less than 2-3 seconds) it switches to the previous song. I would like to implement two different buttons (please, don't ask me why :)) - one for rewinding to the beginning, and one - to moving to previous song. Is there any easy way to do this through IWMPControls (or any other WMP-related COM interface)? p.s. I could handle this if I could get the position (index) of the current song in the list. But as far as I read MSDN, it seems to me that there is no easy way to get the current item index from playlist...

  • Using opencv in Win32 application for image show

    - by erjik
    Is it possible to output images so that they all will be inside a single window? Before, I used to output data using only opencv functions: cvNamedWindow("Image 1"); cvShowImage("Image 1", img); So I change image, then call: cvShowImage function and so on. But If I want to look at more than one image, then every new image needs its own window to be shown there And what I want is to put every such an output opencv's window inside one big main window. Is it possible to do it? And how?

  • Please explain this php expression "!$variable"

    - by DogBot
    What does an exclamaton mark in front of a variable mean? And how is it being used in this piece of code? EDIT: From the answers so far I suspect that I also should mention that this code is in a function where one of the parameters is $mytype ....would this be a way of checking if $mytype was passed? - Thanks to all of the responders so far. $myclass = null; if ($mytype == null && ($PAGE->pagetype <> 'site-index' && $PAGE->pagetype <>'admin-index')) { return $myclass; } elseif ($mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { $myclass = ' active_tree_node'; return $myclass; } elseif (!$mytype == null && ($PAGE->pagetype == 'site-index' || $PAGE->pagetype =='admin-index')) { return $myclass; }`

  • How would I create a VIM or Vi command to delete all text after a certain character for every line i

    - by Jason Down
    Scenario: I have a text file that has pipe (as in the "|" character) delimited data. Each field of data in the pipe delimited fields can be of variable length, so counting characters won't work (or using some sort of substring function... if that even exists in VIM). Is it possible, using VIM / Vi to delete all data from the second pipe to the end of the line for the entire file? There are approx 150,000 lines, so doing this manually would only be appealing to a masochist... e.g. Change the following lines from: 1111|random sized text 12345|more random data la la la|1111|abcde 2222|random sized text abcdefghijk|la la la la|2222|defgh 3333|random sized text|more random data|33333|ijklmnop to: 1111|random sized text 12345 2222|random sized text abcdefghijk 3333|random sized text I'm sure this can be done somehow... I hope. TIA UPDATE: I should have mentioned that I'm running this on Windows XP, so I don't have access to some of the mentioned *nix commands (CUT is not recognized on Windows).

  • Rails: getting logic to run at end of request, regardless of filter chain aborts?

    - by JSW
    Is there a reliable mechanism discussed in rails documentation for calling a function at the end of the request, regardless of filter chain aborts? It's not after filters, because after filters don't get called if any prior filter redirected or rendered. For context, I'm trying to put some structured profiling/reporting information into the app log at the end of every request. This information is collected throughought the request lifetime via instance variables wrapped in custom controller accessors, and dumped at the end in a JSON blob for use by a post-processing script. My end goal is to generate reports about my application's logical query distribution (things that depend on controller logic, not just request URIs and parameters), performance profile (time spent in specific DB queries or blocked on webservices), failure rates (including invalid incoming requests that get rejected by before_filter validation rules), and a slew of other things that cannot really be parsed from the basic information in the application and apache logs. At a higher level, is there a different "rails way" that solves my app profiling goal?

  • How to get a component's parent form in Borland VCL?

    - by nklein
    Hi, I'd like to determine which form a given component belongs to in my application. Neither the Parent nor the Owner property can be assumed to be the form itself, so I can't simply use this. I guess I could just go through the Parent property recursively until I arrive at something derived from TForm, but is there a better way to do this? I used the search function, but couldn't find anything specific to my problem. I'm using Borland C++ Builder, by the way (tagged Delphi because a majority of VCL users seem to write in Delphi, and I read Delphi code just fine). Thanks in advance!

  • LinqToSql: How can I create a projection to adhere to DRY?

    - by mhutter
    Just wondering if there is a way to take some of the repitition out of a LINQ to SQL projected type. Example: Table: Address Fields: AddressID, HouseNumber, Street, City, State, Zip, +20 more Class MyAddress: AddressID, HouseNumber, Street (Only 3 fields) LINQ: from a in db.Addresses select new MyAddress { AddressID = a.AddressID, HouseNumber = a.HouseNumber, Street = a.Street } The above query works perfectly, and I understand why something like this will return all 20+ fields in each row: from a in db.Addresses select new MyAddress(a); class MyAddress { public MyAddress(Address a) { this.AddressID = a.AddressID, this.HouseNumber = a.HouseNumber, this.Street = a.Street } } Which leads me to my Question: Is it possible to implement some kind of helper function or extension method to "map" from the LINQ model to MyAddress yet only return the necessary fields in the query result rather than all of the fields?

  • [Android] GPS can't run inside TimerTask

    - by user568553
    Hi, I am trying to write an android app that acquires a GPS signal at a fix time interval, for example every 1 minute. Since the requestLocationUpdate function does not exactly implement that, I tried to use task to accomplished it. public class getGPS extends TimerTask{ public void run(){ System.out.println("Running a GPS task"); locHandler = new locationUpdateHandler(); myManager.requestLocationUpdates(provider, 60000, 0, locHandler); } } public void LoadCoords(){ Timer timer = new Timer(); timer.scheduleAtFixedRate(new getGPS(), 0, 60000); } However, from what I've seen, requestLocationUpdates would run fine if I put it inside LoadCoords(), but would not run if I put it inside the TimerTask (ie no green icon on the task bar to show that GPS is looking for a fix). Can anyone please suggest an alternative approach or pseudo-code, or correct my mistake if there is one ? Thank you in advance.

  • how to assign to the names() attribute of the value of a variable in R

    - by Tony
    In R, "assign('x',v)" sets the object whose name is 'x' to v. Replace 'x' by the result of applying a text function to a variable x. Then "assign" shows its worth. Unfortunately, "assign(paste('names(','x',')',sep=''),v)" fails. So if 'x' is a variable x, I can set its value, but I can't give it names for its elements. Can one work around this? a parse-eval trick maybe? Thanks.

  • Comments on this assumption about running on dev server vs a real instance in app engine (python)?

    - by Jacob Oscarson
    Hello app engineers! I'm on an app engine project where I'd like to put in a link to a Javascript test runner that I'd like to only exist when running the development server. I've made some experiments on a local shell with configuration loaded using the technique found in NoseGAE versus live on the 'App Engine Console' [1] and it looks to me like a distinction btw real instance and dev server is the presence of the module google.appengine.tools. Which lead me to this utility function: def is_dev(): """ Tells us if we're running under the development server or not. :return: ``True`` if the code is running under the development server. """ try: from google.appengine import tools return True except ImportError: return False The question (finally!) would be: is this a bad idea? And in that case, can anyone suggest a better approach? [1] http://con.appspot.com/console/ (try it! very handy indeed)
