  • How to select and crop an image in android?

    - by Guy
    Hey, I am currently working on a live wallpaper and I allow the user to select an image which will go behind my effects. Currently I have: Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); i.putExtra("crop", "true"); startActivityForResult(i, 1); And slightly under that: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == 1) if (resultCode == Activity.RESULT_OK) { Uri selectedImage = data.getData(); Log.d("IMAGE SEL", "" + selectedImage); // TODO Do something with the select image URI SharedPreferences customSharedPreference = getSharedPreferences("imagePref", Activity.MODE_PRIVATE); SharedPreferences.Editor editor = customSharedPreference.edit(); Log.d("HO", "" + selectedImage); editor.putString("imagePref", getRealPathFromURI(selectedImage)); Log.d("IMAGE SEL", getRealPathFromURI(selectedImage)); editor.commit(); } } When my code is ran, Logcat tells me that selectedImage is null. If I comment out the i.putExtra("crop", "true"): Logcat does not give me the null pointer exception, and I am able to do what I want with the image. So, what is the problem here? Does any one have any idea how I can fix this? Thanks, for your time.

  • Django "login() takes exactly 1 argument (2 given)" error

    - by Oleksandr Bolotov
    I'm trying to store the user's ID in the session using django.contrib.auth.login . But it is not working not as expected. I'm getting error login() takes exactly 1 argument (2 given) With login(user) I'm getting AttributeError at /login/ User' object has no attribute 'method' I'm using slightly modifyed example form http://docs.djangoproject.com/en/dev/topics/auth/ : from django.shortcuts import render_to_response from django.contrib.auth import authenticate, login def login(request): msg = [] if request.method == 'POST': username = request.POST['u'] password = request.POST['p'] user = authenticate(username=username, password=password) if user is not None: if user.is_active: login(request, user) msg.append("login successful") else: msg.append("disabled account") else: msg.append("invalid login") return render_to_response('login.html', {'errors': msg}) there's nothing special about login.html: <html> <head> <title></title> </head> <body> <form action="/login/" method="post"> Login:&nbsp; <input type="text" name="u"> <br/> Password:&nbsp; <input type="password" name="p"> <input type="submit" value="Login"> </form> {% if errors %} <ul> {% for error in errors %} <li>{{ error }}</li> {% endfor %} </ul> {% endif %} </body> </html> Does anybody have idea how to make login() work.

  • Losing 'post' requests sent to Pylons paster server

    - by Philip McDermott
    I'm sending post requests to a Pylons server (served by paster serve), and if I send them with any frequency many don't arrive at the server. One at a time is ok, but if I fire off a few (or more) within seconds, only a small number get dealt with. If I send with no post data, or with get, it works fine, but putting just one character of data in the post fields causes massive losses. For example, sending 200, 2 will come back. Sending 100 more slowly, 10 will come back. I'm making the requests form inside a Qt application. Tis will work ok (no data): QString postFields = "" QNetworkRequest request(QUrl("http://server.com/endpoint")); QNetworkReply *reply = networkAccessManager-post(request, postFields.toAscii()); And this will result in only a fraction of the requests being dealt with: QString postFields = "" QNetworkRequest request(QUrl("http://server.com/endpoint")); QNetworkReply *reply = networkAccessManager-post(request, postFields.toAscii()); I've played around with turning on use_threadpool, and other options (threadpool_workers, threadpool_max_requests = 300), of which some combinations can alter the results slightly (best case 10 responses in 200). If I send similar requests to other (non paster) servers, the replies come back ok, so I'm almost certain its'a paster serve config issue. Any help or advice greatly appreciated. Thanks Philip

  • CSRF Protection in AJAX Requests using MVC2

    - by mnemosyn
    The page I'm building depends heavily on AJAX. Basically, there is just one "page" and every data transfer is handled via AJAX. Since overoptimistic caching on the browser side leads to strange problems (data not reloaded), I have to perform all requests (also reads) using POST - that forces a reload. Now I want to prevent the page against CSRF. With form submission, using Html.AntiForgeryToken() works neatly, but in AJAX-request, I guess I will have to append the token manually? Is there anything out-of-the box available? My current attempt looks like this: I'd love to reuse the existing magic. However, HtmlHelper.GetAntiForgeryTokenAndSetCookie is private and I don't want to hack around in MVC. The other option is to write an extension like public static string PlainAntiForgeryToken(this HtmlHelper helper) { // extract the actual field value from the hidden input return helper.AntiForgeryToken().DoSomeHackyStringActions(); } which is somewhat hacky and leaves the bigger problem unsolved: How to verify that token? The default verification implementation is internal and hard-coded against using form fields. I tried to write a slightly modified ValidateAntiForgeryTokenAttribute, but it uses an AntiForgeryDataSerializer which is private and I really didn't want to copy that, too. At this point it seems to be easier to come up with a homegrown solution, but that is really duplicate code. Any suggestions how to do this the smart way? Am I missing something completely obvious?

  • AVAudioPlayer working in Simulator, but not on device

    - by cannyboy
    My mp3 playing code is: NSError *error; soundObject = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:audioPathString] error:&error]; if (soundObject == nil) NSLog(@"%@", [error description]); soundObject.delegate = self; soundObject.numberOfLoops = 0; soundObject.volume = 1.0; NSLog(@"about to play"); [soundObject prepareToPlay]; [soundObject play]; NSLog(@"[soundObject play];"); The mp3 used to play fine, and it still does on the simulator. But not on the device. I've recently added some sound recording code (not mine) to the software. It uses AudioQueue stuff which is slightly beyond me. Does that conflict with AVAudioPlayer? Or what could be the problem? I've noticed that as soon as the audiorecording code starts working, I can't adjust the volume on the device anymore, so maybe it blocks the audio playback?. EDIT The solution seems to be to put this in my code. I put it in applicationDidFinishLaunching: [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayAndRecord error: nil]; UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker; AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,sizeof (audioRouteOverride),&audioRouteOverride); The first line allows both play and record, whilst the other lines apparently reroute things to make the volume louder. All audio code is voodoo to me.

  • onmouseover problems with JavaScript (rendered using django and django-imagekit)

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • When can a == b be false and a.Equals(b) true?

    - by alastairs
    I ran into this situation today. I have an object which I'm testing for equality; the Create() method returns a subclass implementation of MyObject. MyObject a = MyObject.Create(); MyObject b = MyObject.Create(); a == b; // is false a.Equals(b); // is true Note I have also over-ridden Equals() in the subclass implementation, which does a very basic check to see whether or not the passed-in object is null and is of the subclass's type. If both those conditions are met, the objects are deemed to be equal. The other slightly odd thing is that my unit test suite does some tests similar to Assert.AreEqual(MyObject.Create(), MyObject.Create()); // Green bar and the expected result is observed. Therefore I guess that NUnit uses a.Equals(b) under the covers, rather than a == b as I had assumed. Side note: I program in a mixture of .NET and Java, so I might be mixing up my expectations/assumptions here. I thought, however, that a == b worked more consistently in .NET than it did in Java where you often have to use equals() to test equality.

  • Problem inserting android.text.format.Time.toMillis value into SQLite DB on droid

    - by schusselig
    I'm writing an app for Android OS, and I need to store some time values in the SQLite DB. I have been using android.text.format.Time to store the time values in the app, and then inserting the values as millis into the DB as REAL values. On the SDK emulator, everything works perfectly. On the sole phone I've had the opportunity to test my app (so far), my duration code doesn't work as expected. Some relevant code: private static final String DATABASE_CREATE = "create table " + DATABASE_TABLE + " (" + KEY_ROWID + " integer primary key autoincrement, " + KEY_START + " REAL, " + KEY_STOP + " REAL, " + KEY_DUR + " REAL );"; ... private SQLiteDatabase mDb; ContentValues timerValues = new ContentValues(); ... timerValues.put(KEY_START, stime.toMillis(false)); timerValues.put(KEY_STOP, etime.toMillis(false)); timerValues.put(KEY_DURATION, stime.toMillis(false)-etime.toMillis(false)); int result = mDb.insert(DATABASE_TABLE, null, timerValues); I pull this data from two separate functions with slightly different bits of code, both using Time.set(long millis), both giving incorrect results: The start and stop values come back correct, but the duration comes out 17 hours too large. Am I missing something about calculating durations or does this just seem like there's something "special" about this particular droid? I'll have another droid to test on Monday, but any ideas are appreciated.

  • Beginner SQL question: querying gold and silver tag badges in Stack Exchange Data Explorer

    - by polygenelubricants
    I'm using the Stack Exchange Data Explorer to learn SQL, but I think the fundamentals of the question is applicable to other databases. I'm trying to query the Badges table, which according to Stexdex (that's what I'm going to call it from now on) has the following schema: Badges Id UserId Name Date This works well for badges like [Epic] and [Legendary] which have unique names, but the silver and gold tag-specific badges seems to be mixed in together by having the same exact name. Here's an example query I wrote for [mysql] tag: SELECT UserId as [User Link], Date FROM Badges Where Name = 'mysql' Order By Date ASC The (slightly annotated) output is: as seen on stexdex: User Link Date --------------- ------------------- // all for silver except where noted Bill Karwin 2009-02-20 11:00:25 Quassnoi 2009-06-01 10:00:16 Greg 2009-10-22 10:00:25 Quassnoi 2009-10-31 10:00:24 // for gold Bill Karwin 2009-11-23 11:00:30 // for gold cletus 2010-01-01 11:00:23 OMG Ponies 2010-01-03 11:00:48 Pascal MARTIN 2010-02-17 11:00:29 Mark Byers 2010-04-07 10:00:35 Daniel Vassallo 2010-05-14 10:00:38 This is consistent with the current list of silver and gold earners at the moment of this writing, but to speak in more timeless terms, as of the end of May 2010 only 2 users have earned the gold [mysql] tag: Quassnoi and Bill Karwin, as evidenced in the above result by their names being the only ones that appear twice. So this is the way I understand it: The first time an Id appears (in chronological order) is for the silver badge The second time is for the gold Now, the above result mixes the silver and gold entries together. My questions are: Is this a typical design, or are there much friendlier schema/normalization/whatever you call it? In the current design, how would you query the silver and gold badges separately? GROUP BY Id and picking the min/max or first/second by the Date somehow? How can you write a query that lists all the silver badges first then all the gold badges next? Imagine also that the "real" query may be more complicated, i.e. not just listing by date. How would you write it so that it doesn't have too many repetition between the silver and gold subqueries? Is it perhaps more typical to do two totally separate queries instead? What is this idiom called? A row "partitioning" query to put them into "buckets" or something?

  • How do you query namespaces with PHP/XPath/DOM

    - by Alsbury
    I am trying to query an XML document that uses namespaces. I have had success with xpath without namespaces, but no results with namespaces. This is a basic example of what I was trying. I have condensed it slightly, so there may be small issues in my sample that may detract from my actual problem. Sample XML: <?xml version="1.0"?> <sf:page> <sf:section> <sf:layout> <sf:p>My Content</sf:p> </sf:layout> </sf:section> </sf:page> Sample PHP Code: <?php $path = "index.xml"; $content = file_get_contents($path); $dom = new DOMDocument($content); $xpath = new DOMXPath($dom); $xpath->registerNamespace('sf', "http://developer.apple.com/namespaces/sf"); $p = $xpath->query("//sf:p", $dom); My result is that "p" is a "DOMNodeList Object ( )" and it's length is 0. Any help would be appreciated.

  • Is there a way to get YQL to return HTML?

    - by Joe Shaw
    I am trying to use YQL to extract a portion of HTML from a series of web pages. The pages themselves have slightly different structure (so a Yahoo Pipes "Fetch Page" with its "Cut content" feature does not work well) but the fragment I am interested in always has the same class attribute. If I have an HTML page like this: <html> <body> <div class="foo"> <p>Wolf</p> <ul> <li>Dog</li> <li>Cat</li> </ul> </div> </body> </html> and use a YQL expression like this: SELECT * FROM html WHERE url="http://example.com/containing-the-fragment-above" AND xpath="//div[@class='foo']" what I get back are the (apparently unordered?) DOM elements, where what I want is the HTML content itself. I've tried SELECT content as well, but that only selects textual content. I want HTML. Is this possible?

  • Questions about the MVC architecture

    - by ah123
    I started coding a considerably complicated web application, and it became quite a mess. So I figured I'd try to organize it in a better way. MVC seemed appropriate. I've never used MVC before, and researching about it I'm trying to consolidate a better perception of it (and my questions obviously reflect what I think I've learned so far). My questions are slightly JavaScript oriented: What object should make "AJAX" requests? The Controller or the Model? (seperation -- should the Model just store/manipulate the data, should it not care/know where the data came from, or should it be the one fetching it?) Should the Model call View functions providing them with data as arguments or should the View query (reference) the Model within itself? (seperation principles in mind, "the View shouldn't care/know where it gets the data from" -- is that correct?) In general, should the View "know" of the Model's existance, and vice-versa? Is the Controller the only thing gluing them together or is that simply incorrect? (I really doubt that statement is generally correct) There's a good chance I'd want to port this into a desktop/mobile application, so I would like to seperate components in a way that will allow me to achieve that task, replacing the current source of the data, HTTP requests, with DB access, and replacing the View. Maybe every approach that I've asked about is still "valid" MVC and it's just up to me to choose. I understand that nothing is set in stone, I'm just trying to have a (better) general idea in my head.

  • Resizing video best practices (frame size)

    - by undefined
    I have read the following which is from Best Practices for Encoding Video with the VP6 Codec on the Adobe website here - http://www.adobe.com/devnet/flash/articles/encoding_video_print.html. It is talking about common video ratios (320x240, 640x480) Although these ratios are standard, and should be used to avoid distorting the video, the size of the encoded video is not set in stone. The original web video sizes used heights and widths that were evenly divisible by 16. This was mandatory for many early codecs. Although this is not necessary for modern codecs, you should stick to even heights and widths. What do they mean by 'even heights and widths'. I am thinking about encoding my video at 400x300 to make it slightly bigger, this is still 4x3 format but should I just stick at 320x240 and resize it on the screen? Clearly there are benefits to this in terms of storage size and delivery costs. In some places on my site I want to show the video at 400x300 but in others I want it to play full screen so this is why I am wondering if a larger original size (400x300) will give better results when blown up. Any thoughts?

  • Status Code from FTPWebRequest GetResponse method

    - by nick
    This is slightly tricky. I am uploading files to FTP asynchronously. After uploading each file I am checking the status of the upload operation for that file. This can be done with StatusCode property of the FtpWebResponse object for that request. The code snippet is as give below. System.IO.FileStream fs = System.IO.File.Open(fileName, System.IO.FileMode.Open); while ((iWork = fs.Read(buf, 0, buf.Length)) > 0) requestStream.Write(buf, 0, iWork); requestStream.Close(); FtpWebResponse wrRet = ((FtpWebResponse)state.Request.GetResponse()); There are about 37 StatusCode values as per msdn. I am unaware as to which of these status code values will assure that the file is uploaded successfully. Some of them I used in my code to check for success are : wrRet.StatusCode == FtpStatusCode.CommandOK wrRet.StatusCode == FtpStatusCode.ClosingData wrRet.StatusCode == FtpStatusCode.ClosingControl wrRet.StatusCode == FtpStatusCode.ConnectionClosed wrRet.StatusCode == FtpStatusCode.FileActionOK wrRet.StatusCode == FtpStatusCode.FileStatus But I am unaware of the rest. I need to be sure about these codes because based on the failure or success of the upload operation I have other dependant operations to be carried out. A wrong condition can affect the remaining code. Another thought that crossed my mind was to simply put the above code into a try..catch and not depend on these status codes. With this I would not be depending on the status codes and assuming that any failure will always be directed to the catch block. Kindly let me know if this is the right way. Thanks in advance.

  • Using MinHash to find similiarities between 2 images

    - by Sung Meister
    I am using MinHash algorithm to find similar images between images. I have run across this post, How can I recognize slightly modified images? which pointed me to MinHash algorithm. Being a bit mathematically challenged, I was using a C# implementation from this blog post, Set Similarity and Min Hash. But while trying to use the implementation, I have run into 2 problems. What value should I set universe value to? When passing image byte array to HashSet, it only contains distinct byte values; thus comparing values from 1 ~ 256. What is this universe in MinHash? And what can I do to improve the C# MinHash implementation? Since HashSet<byte> contains values upto 256, similarity value always come out to 1. Here is the source that uses the C# MinHash implementation from Set Similarity and Min Hash: class Program { static void Main(string[] args) { var imageSet1 = GetImageByte(@".\Images\01.JPG"); var imageSet2 = GetImageByte(@".\Images\02.TIF"); //var app = new MinHash(256); var app = new MinHash(Math.Min(imageSet1.Count, imageSet2.Count)); double imageSimilarity = app.Similarity(imageSet1, imageSet2); Console.WriteLine("similarity = {0}", imageSimilarity); } private static HashSet<byte> GetImageByte(string imagePath) { using (var fs = new FileStream(imagePath, FileMode.Open, FileAccess.Read)) using (var br = new BinaryReader(fs)) { //List<int> bytes = br.ReadBytes((int)fs.Length).Cast<int>().ToList(); var bytes = new List<byte>(br.ReadBytes((int) fs.Length).ToArray()); return new HashSet<byte>(bytes); } } }

  • Manually Writing the HTML in TWebBrowser Pt. 2

    - by nomad311
    As the name suggests this is a continuation (sort of) of http://stackoverflow.com/questions/2784679/manually-writing-the-html-in-twebbrowser This time around I'm trying to add some auto-refresh logic to the HTML I get. I have pieced together an approach from several sources (see below). In short, I am trying to locate the title node and add a meta node after it (in the HTML head node). But, I get an access violation. Here is the source: iHtmlDoc := IHTMLDocument3(WebBrowser1.Document); iHtmlEleTitle := IHTMLElement2(iHtmlDoc.getElementsByName('title').item(0, 0)); iHtmlEle := IHTMLElement2(IHTMLDocument2(iHtmlDoc).createElement(Format('<meta http-equiv="refresh" content="%d">', [1]))); iHtmlEleTitle.insertAdjacentElement('afterEnd', IHTMLElement(iHtmlEle)); And A (technically not functionally) different way of doing it ...casting is slightly different here: IHTMLElement2(IHtmlDocument3(WebBrowser1.Document).getElementsByName('title').item(0, 0)).insertAdjacentElement('afterEnd', IHTMLDocument2(WebBrowser1.Document).createElement(Format('<meta http-equiv="refresh" content="%d">', [VPI_ISSUANCE_AUTO_RELOAD]))); Again all I get from Delphi is a access exception, and I fished through MSDN documentation on it, but now I'm hoping someone out there has gone through the same and has some insight. Any help?

  • ildasm and dynamic exe files

    - by TonyNeallon
    Hi There, I am trying to create an application can modify properties in IL to create a slightly different executable. E.g Client A runs app and a label on the WinForm label Reads "Client A:". Client B runs the app and Label Says "Client B". Easy I know using config files or resource files but thats not an option for this project. The Main program needs to be able to generate .exe file dynamically based on some form fields entered by user. My solution was to create a standalone executable that contained all the elements which I needed to make dynamic. I then used ildasm to generate the IL and thought that I could use this IL and substitute tags for the elements i wanted to make dynamic. I could then replace those tags at runtime after user filled the form using regex etc. The problem is, the if i re save the IL file generated by ILDASM as an exe and try to run it. I just launches console and does nothing. Am I going about this the wrong way? I didnt want to delve into Reflection as the dynamic .exe is a really simple one and I thought reverse engineering IL with ildasm would be the quickest way. You thoughts and pointers are much appreciated. Tony

  • .NET regex: Match.nextMatch() never returns

    - by Jimmy
    I have a regex that seems to have worked fine for the past year or so, and all of a sudden today with a new slightly different text to match against, Match.nextMatch() never returns. I'm no regex expert and I'm sure the regex can be optimized, but previous data sets weren't much more complex than what I've tried today. Furthermore, the regex works fine against the offending data set in a tool like RegexBuddy; it's only in .net (running in debug in Visual Studio) that it seems to hang. Nevertheless, if anyone can figure out how to tweak the regex to make it work, I'd really appreciate it. This is the regex: <tr>(<td[^>]*><a[^>]*>(?<callOptionTicker>[A-Z]{1,5}\d{6}C\d{8})</a></td>)(<td[^>]*>.*?</td>){6}(<td[^>]*><b><a[^>]*>(?<strikePrice>\d*\.\d*)</a></b></td>)(<td[^>]*><a[^>]*>(?<putOptionTicker>[A-Z]{1,5}\d{6}P\d{8})</a></td>) It's meant to extract put and call option tickers from a Yahoo option chain page (i.e., raw HTML). It works fine for IBM http://finance.yahoo.com/q/os?s=IBM&m=2010-05-21 It doesn't work for SPX options (this is the offending data set) http://finance.yahoo.com/q/os?s=I:SPX.W&m=2010-05

  • Algorithm to find the percentage of how much two texts are identical

    - by qster
    What algorithm would you suggest to identify how much from 0 to 1 (float) two texts are identical? Note that I don't mean similar (ie, they say the same thing but in a different way), I mean exact same words, but one of the two texts could have extra words or words slightly different or extra new lines and stuff like that. A good example of the algorithm I want is the one google uses to identify duplicate content in websites (X search results very similar to the ones shown have been omitted, click here to see them). The reason I need it is because my website has the ability for users to post comments; similar but different pages currently have their own comments, so many users ended up copy&pasting their comments on all the similar pages. Now I want to merge them (all similar pages will "share" the comments, and if you post it on page A it will appear on similar page B), and I would like to programatically erase all those copy&pasted comments from the same user. I have quite a few million comments but speed shouldn't be an issue since this is a one time thing that will run in the background. The programming language doesn't really matter (as long as it can interface to a MySQL database), but I was thinking of doing it in C++.

  • how to 'scale' these three tables?

    - by iddqd
    I have the following Tables: Players id playerName Weapons id type otherData Weapons2Player id playersID_reference weaponsID_reference That was nice and simple. Now I need to SELECT items from the Weapons table, according to some of their characteristics that i previously just packed into the otherData column (since it was only needed on the client side). The problem is, that the types have varying characteristics - but also a lot of similar data. So I'm trying to decide on the following possibilities, all of which have their pros and cons. Solution A Kill the Weapons table, and create a new table for each Weapon-Type: Weapons_Swords id bladeType damage otherData Weapons_Guns id accuracy damage ammoType otherData But how will i Link these to the Players ? create Weapons_Swords2Players, Weapons_Guns2Players for each weapon-type? (Will result in a lot more JOINS when loading the player with all his weapons...and it's also more complicated to insert a new player) or add another column to Weapons2Players called WeaponsTypeTable, then do sub-selects to the correct Weapons sub-table (seems easier, but not really right, slightly easier insert i guess) Solution B Keep the Weapons table, and add all the fields i need to it. The Problem is that then there will be NULL fields, since not all Weapon-Types use all fields (can't be right) Weapons id type accuracy damage ammoType bladeType otherData This seems to be pretty basic stuff, but i just can't decide what's best. Or is there a correct Solution C? many thanks.

  • target-action uicontrolevents

    - by Fabrizio Farinelli
    I must be missing something obvious here but ... UIControl has a method - (void)addTarget:(id)target action:(SEL)action forControlEvents: (UIControlEvents)controlEvents which lets you add an action to be called when any of the given controlEvents occur. ControlEvents are a bitmask of events which tell you if a touch went down, or up inside, or was dragged etc., there's about 16 of them, you or them together and get called when any of them occur. The selector can have one of the following signatures - (void)action - (void)action:(id)sender - (void)action:(id)sender forEvent:(UIEvent *) none of those tell you what the control event bitmask was. The UIEvent is something slightly different, it's related to the actual touch event and doesn't (I think) contain the UIControlEvent. The sender (UIControl) doesn't have a way to find the control events either. I'd like to have one method which deals with a number of control events as I have some common code regardless of which event or events happened but I still need to know what the UIControlEvents were for some specific processing. Am I missing a way to find out what UIControlEvents were used when the action was called or do I really have to separate my code into -(void)actionWithUIControlEventX; -(void)actionWithUIControlEventY;

  • How to move the Windows 7 bootloader to the Windows 7 partition?

    - by pauldoo
    I recently installed Windows 7 in a triple boot setup alongside XP and Linux. When I was finished and was in the process of restoring the bootloader for Linux I discovered something strange about what Windows 7 had done. I discovered that Windows 7 had not installed a bootloader to it's own partition, and instead had instead set up a bootloader on the pre-existing XP partition that offers a choice between 7 and XP. This behaviour has been noticed by others. Now my booting is slightly odd. I have GRUB on the MBR which lets me choose between Linux and Windows. When I select Windows I have Grub boot to the XP partition where I get the 2nd choice between 7 and XP. Why doesn't the Windows 7 installer put the Windows 7 bootloader on the Windows 7 partition like all previous MS OSs? This is now going to be a real problem for me, as I now want to wipe the XP partition and install something else there (probably another non-MS OS). How can I move the bootloader for Windows 7 onto the Windows 7 partition, thus making it bootable and allowing me to safely wipe the XP partition?

  • PHPUnit and autoloaders: Determining whether code is running in test-scope?

    - by pinkgothic
    Premise I know that writing code to act differently when a test is run is hilariously bad practise, but I may've actually come across a scenario in which it may be necessary. Specifically, I'm trying to test a very specific wrapper for HTML Purifier in the Zend framework - a View Helper, to be exact. The HTML Purifier autoloader is necessary because it uses a different logic to the autoloaders we otherwise have. Problem require()-ing the autoloader at the top of my View Helper class, gives me the following in test-scope: HTML Purifier autoloader registrar is not compatible with non-static object methods due to PHP Bug #44144; Please do not use HTMLPurifier.autoload.php (or any file that includes this file); instead, place the code: spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) after your own autoloaders. Replacing the require() with spl_autoload_register(array('HTMLPurifier_Bootstrap', 'autoload')) as advertised means the test runs fine, but the View Helper dies a terrible death claiming: Zend_Log[3707]: ErrorController caught LogicException "Passed array does not specify an existing static method (class 'HTMLPurifier_Bootstrap' not found)" (Our test folder structure is slightly different to our Zend folder structure by necessity.) Question(s) After tinkering with it, I'm thinking I'll need to pick an autoloader-loading depending on whether things are in the test scope or not. Do I have another option to include HTMLPurifier's autoloading routine in both cases that I'm not seeing due to tunnel vision? If not, do I have to find a means to differentiate between test-environment and production-environment this with my own code (e.g. APPLICATION_ENV) - or does PHPUnit support this godawful hackery of mine natively by setting a constant that I could check whether its been defined(), or similar shenanigans? (My Google-fu here is weak! I'm probably just doing it wrong.)

  • Why This Maintainability Index Increase?

    - by Timothy
    I would be appreciative if someone could explain to me the difference between the following two pieces of code in terms of Visual Studio's Code Metrics rules. Why does the Maintainability Index increase slightly if I don't encapsulate everything within using ( )? Sample 1 (MI score of 71) public static String Sha1(String plainText) { using (SHA1Managed sha1 = new SHA1Managed()) { Byte[] text = Encoding.Unicode.GetBytes(plainText); Byte[] hashBytes = sha1.ComputeHash(text); return Convert.ToBase64String(hashBytes); } } Sample 2 (MI score of 73) public static String Sha1(String plainText) { Byte[] text, hashBytes; using (SHA1Managed sha1 = new SHA1Managed()) { text = Encoding.Unicode.GetBytes(plainText); hashBytes = sha1.ComputeHash(text); } return Convert.ToBase64String(hashBytes); } I understand metrics are meaningless outside of a broader context and understanding, and programmers should exercise discretion. While I could boost the score up to 76 with return Convert.ToBase64String(sha1.ComputeHash(Encoding.Unicode.GetBytes(plainText))), I shouldn't. I would clearly be just playing with numbers and it isn't truly any more readable or maintainable at that point. I am curious though as to what the logic might be behind the increase in this case. It's obviously not line-count.

  • DOJO : How do you reinitiate form elements after ajax call ?

    - by Dural
    I'm trying to do a couple of things using Zend Framework & Dojo Toolkit, and any help would be appreciated. Here's the problem: I have a form that is rendered with the Zend Framework form class, which has an ajax radio button selection. Clicking one of these radio buttons will send an ajax request to another controller, which has no layout, just a rendered form. The ajax request will then populate a div with the new form options. Problem is, when I replace the innerHTML of the div with the ajax response, all the form inputs and elements are not inheriting the same Dojo styling and form validation. I was wondering if there is a way to reinitate form elements after an ajax call? I have tried to use the code attached which I found and modified slightly for this example, however it did not work. If I use the line dojo.parser.parse( div ); nothing changes (rg_adress in the example is the ID of a form element that is placed on the DOM). Here is the console.log of rg_address: <input type="text" dojotype="dijit.form.ValidationTextBox" required="1" invalidmessage="The first name of the recipient" value="" name="rg_address" id="rg_address" class="textbox"/> onClick=' dojo.xhrGet( { url: "/transfer/newrecipient/", handleAs: "text", timeout: 10000, // Time in milliseconds // The LOAD function will be called on a successful response. load: function(response, ioArgs) { $("#newRecipient").html(response); $("#newPayMethod").html(""); $("#newPayDetail").html(""); var div = dojo.byId("rg_address"); console.log( div ); dojo.parser.parse( div ); return response; }, // The ERROR function will be called in an error case. error: function(response, ioArgs) { $("#newRecipient").html("Error loading registration form"); $("#newPayMethod").html(""); $("#newPayDetail").html(""); return response; } });' Thanks, Dural
