  • Sending multipart response for downloads in Zend Framework

    - by takeshin
    I'm sending files in action helper for downloads (in parts if needed) like this: ... $response->sendHeaders(); $chunksize = 1 * (1024 * 1024); $bytesSent = 0; if ($httpRange) { fseek($file, $range); } while(!feof($file) && (!connection_aborted() && ($bytesSent < $newLength)) ) { $buffer = fread($file, $chunksize); // $response->appendBody($buffer); // this would be better print($buffer); flush(); $bytesSent += strlen($buffer); } fclose($file); I suspect that better way would be to make use of $response object instead of print. Which is the recommended way to send big response objects using Zend Framework?

  • Module import error using IDLE

    - by Nimbuz
    I'm an absolute beginner using IDLE (Python 2.6.4) to learn the basics. I recently found a Python program that I want to run but it throws an error although the code looks fine (i.e all modules exist): from css.parse import parse data = """ em { padding: 2px; margin: 1em; border-width: medium; border-style: dashed; line-height: 2.4em; } p { color: red; font-size: 12pt } p:first-letter { color: green; font-size: 200% } p:first-line { color: blue }""" for rule in parse(data): print rule for decl in parse(data)[0]: print decl Error: ImportError: No module named parse How do I fix this? I'm using Snow Leopard. Edit: I guess its a PATH issue, where should I place the modules, which directory?

  • How to get child container reference in View Model

    - by niels-verkaart
    Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

  • Android application transparency and window sizing at root level

    - by ajoburg
    Is it possible to create an application with a transparent background on the root task such that you can see the task running beneath it when it is part of a separate stack? Alternatively, is it possible to run an application so the window of the root task is only a portion of the screen instead of the whole screen? I understand how the transparency and window sizing is done with activities that are not the root task and this works fine. However, the root task of an activity seems to always fill the whole screen and be black even when a transparent theme is applied to the application object in the manifest file. ApplicationManifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true" android:theme="@style/Theme.Transparent"> Styles.xml <resources> <style name="Theme.Transparent"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowNoTitle">true</item> <item name="android:windowBackground">@drawable/ transparent_background</item> <item name="android:windowAnimationStyle">@android:style/ Animation.Translucent</item> <item name="android:colorForeground">#fff</item> <item name="android:windowIsFloating">true</item> <item name="android:gravity">bottom</item> </style> </resources> Colors.xml <resources> <drawable name="transparent_background">#00000000</drawable> </resources>

  • Implicitly invoking parent class initializer

    - by Matt Joiner
    class A(object): def __init__(self, a, b, c): #super(A, self).__init__() super(self.__class__, self).__init__() class B(A): def __init__(self, b, c): print super(B, self) print super(self.__class__, self) #super(B, self).__init__(1, b, c) super(self.__class__, self).__init__(1, b, c) class C(B): def __init__(self, c): #super(C, self).__init__(2, c) super(self.__class__, self).__init__(2, c) C(3) In the above code, the commented out __init__ calls appear to the be the commonly accepted "smart" way to do super class initialization. However in the event that the class hierarchy is likely to change, I have been using the uncommented form, until recently. It appears that in the call to the super constructor for B in the above hierarchy, that B.__init__ is called again, self.__class__ is actually C, not B as I had always assumed. Is there some way in Python-2.x that I can overcome this, and maintain proper MRO when calling super constructors without actually naming the current class?

  • Common Pitfalls in Python

    - by Anurag Uniyal
    Today I was bitten again by "Mutable default arguments" after many years. I usually don't use mutable default arguments unless needed but I think with time I forgot about that, and today in the application I added tocElements=[] in a pdf generation function's argument list and now 'Table of Content' gets longer and longer after each invocation of "generate pdf" :) My question is what other things should I add to my list of things to MUST avoid? Mutable default arguments Import modules always same way e.g. from y import x and import x are different things, they are treated as different modules. Do not use range in place of lists because range() will become an iterator anyway, the following will fail: myIndexList = [0,1,3] isListSorted = myIndexList == range(3) # will fail in 3.0 isListSorted = myIndexList == list(range(3)) # will not same thing can be mistakenly done with xrange: `myIndexList == xrange(3)`. Catching multiple exceptions try: raise KeyError("hmm bug") except KeyError,TypeError: print TypeError It prints "hmm bug", though it is not a bug, it looks like we are catching exceptions of type KeyError,TypeError but instead we are catching KeyError only as variable TypeError, use this instead: try: raise KeyError("hmm bug") except (KeyError,TypeError): print TypeError

  • Frame Accurate Browser Launchable Video Player ... ?

    - by cliftonc
    I have a requirement where I need to enable playback (full screen) of a h.264 MPEG4 (thanks for the correction!) video from a local network, launchable from a browser link on a Windows workstation, and be frame accurate. By frame accurate I mean that I need to be able to scrub through the video in the same way you would with a vtr, stop at a frame, and then move backwards and forwards frame by frame (it is for a very specific compliance requirement where have to be able to check every frame if there is something that is potentially against broadcasting guidelines). The application itself is used to capture notes while viewing the material, so the end model is for a dual monitor workstation, with a web form in one, the video playing full screen in the second (no issue launching the video and manually having to move it to the second screen), and then the user controls the video via keyboard shortcuts or a jog shuttle. I have looked at QT, but the java bindings seem to be dead or nearly so, flash isn't frame accurate, VLC given its streaming heritage seems to be only able to move forward by a frame and not backwards, and all I have left are commercial offerings that in my experience are difficult and expensive to change. Any ideas of where I should look or alternative options? Any advice appreciated!

  • Wrong IO actions order using putStr and getLine

    - by QWRp
    I have a code : main = do putStr "Test input : " content <- getLine putStrLn content And when I run it (with runhaskell) or compile it (ghc 6.10.4) result is like this: asd Test input : asd I'm new to haskell and in my opinion printing should be first. Am I right? In code sample on http://learnyouahaskell.com/ which used putStr then getLine presented output is different than mine (IMHO correct). When I use putStrLn program works as expected (print then prompt and print). Is it a bug in ghc, or it is the way that it should work?

  • Level-order in Haskell

    - by brain_damage
    I have a structure for a tree and I want to print the tree by levels. data Tree a = Nd a [Tree a] deriving Show type Nd = String tree = Nd "a" [Nd "b" [Nd "c" [], Nd "g" [Nd "h" [], Nd "i" [], Nd "j" [], Nd "k" []]], Nd "d" [Nd "f" []], Nd "e" [Nd "l" [Nd "n" [Nd "o" []]], Nd "m" []]] preorder (Nd x ts) = x : concatMap preorder ts postorder (Nd x ts) = (concatMap postorder ts) ++ [x] But how to do it by levels? "levels tree" should print ["a", "bde", "cgflm", "hijkn", "o"]. I think that "iterate" would be suitable function for the purpose, but I cannot come up with a solution how to use it. Would you help me, please?

  • Printing images in Flex

    - by TERACytE
    In s Flex 3 app, I have canvas with a PNG image for a background. The image is the same width & height as the canvas. I also have some other controls in the canvas: <mx:Canvas id="form" backgroundImage="@Embed(source='images/formBkg.png')" width="640" height="480" > <mx:label .../> <mx:label .../> I print the canvas using the following code: var printJob:FlexPrintJob = new FlexPrintJob(); if (printJob.start()) { printJob.addObject(form, FlexPrintJobScaleType.SHOW_ALL); printJob.send(); } On screen it looks great, but when I print it the quality of the png degrades. It is not terrible, but not as sharp as what is shown on screen. Is there anything I can do to improve the quality of the printed png?

  • Java parsing UTF8

    - by Jack
    I have the following issue with a UTF8 files structured as following: FIELD1§FIELD2§FIELD3§FIELD4 Looking at hexadecimal values of the file it uses A7 to codify §. So according to this codify it should be UTF8, but it's strange because A7 7F so 1 byte shouldn't be enough to codify §. So I tried using directly a BufferedReader with a specified charset: BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(input), utf8)) but when I try to tokenize the string with SmartTokenizer st = new SmartTokenizer(toTokenize, "§") (the SmartTokenizer is a modified version of the StringTokenizer that keeps empty tokens) no splitting occurs, and if I try to print the string I obtain FIELD1?FIELD2?FIELD3?... so § used in the file is different from the one specified as a the delimiter, and it's not able to print out it too. So what's the problem here? Maybe the original file should use 2 bytes to store §?

  • Is there a way to circumvent Python list.append() becoming progressively slower in a loop as the lis

    - by Deniz
    I have a big file I'm reading from, and convert every few lines to an instance of an Object. Since I'm looping through the file, I stash the instance to a list using list.append(instance), and then continue looping. This is a file that's around ~100MB so it isn't too large, but as the list grows larger, the looping slows down progressively. (I print the time for each lap in the loop). This is not intrinsic to the loop ~ when I print every new instance as I loop through the file, the program progresses at constant speed ~ it is only when I append them to a list it gets slow. My friend suggested disabling garbage collection before the while loop and enabling it afterward & making a garbage collection call. Did anyone else observe a similar problem with list.append getting slower? Is there any other way to circumvent this?

  • Connecting to Python XML RPC from the Mac

    - by MAC
    Hi, I wrote an XML RPC server in python and a simple Test Client for it in python. The Server runs on a linux box. I tested it by running the python client on the same linux machine and it works. I then tried to run the python client on a Mac and i get the following error socket.error: (61, 'Connection Refused') I can ping and ssh into the linux machine from the Mac. So i dont think its a configuration or firewall error. Does anyone have any idea what could be going wrong? The code for the client is as below: import xmlrpclib s = xmlrpclib.ServerProxy('http://143.252.249.141:8000') print s.GetUsers() print s.system.listMethods()

  • jQuery ui datepicker positioning problem when scrolling down webpage

    - by Remnant
    I have a webpage that uses multiple instances of the jQuery ui datepicker. My webpage will display ~80 records which extends beyond a single screenshot. <% foreach (var record in Model) { %> <div class="recordname"><%=record.name%></div> <%=Html.TextBox("DateTimePicker", null, new { @class = "date-pick" } )%> // <-- additional html here --> <% } %> I have set the defaults of my datepicker as follows: $(".date-pick").each(function() { $(this).datepicker({ dateFormat: 'dd M yy', showOn: 'button', buttonImage: '/Images/datepickericon.png', buttonImageOnly: true }); }); When the page first loads, if I click any datepicker icon that is visible on screen (i.e. without scrolling) then the datepicker appears as expected. However, if I scroll down the page and then click a datepicker icon, the datepicker does not appear in the screen window but is instead rendered right back near the top of the screen. Any ideas how to solve this? I am using: IE7 asp.net mvc jquery.ui.datepicker.js (UI/API/1.8/Datepicker)

  • Iterating through nested dictionaries

    - by Framester
    I want to write an iterator for my 'toy' Trie implementation. Adding already works like this: class Trie: def __init__(self): self.root = dict() pass def add(self, string, value): global nops current_dict = self.root for letter in s: nops += 1 current_dict = current_dict.setdefault(letter, {}) current_dict = current_dict.setdefault('value', value) pass The output of the adding looks like that: trie = Trie() trie.add("hello",1) trie.add("world",2) trie.add("worlds",12) print trie.root {'h': {'e': {'l': {'l': {'o': {'value': 1}}}}}, 'w': {'o': {'r': {'l': {'d': {'s': {'value': 2}, 'value': 2}}}}}} I know, that I need a __iter__ and next method. def __iter__(self): self.root.__iter__() pass def next(self): print self.root.next() But AttributeError: 'dict' object has no attribute 'next'. How should I do it? [Update] In the perfect world I would like the output to be one dict with all the words/entries with their corresponding values.

  • Redmon's Run As User not loading user's enviroment variables

    - by catfish
    I'm attempting to use Redmon http://www.winimage.com/misc/redmon/ to send print jobs to a custom C# application. Redmon "runs" (actually the Print Spooler) as SYSTEM but has an option to Run As User to allow your application to run under the user that printed the job. The problem is that it doesn't appear to load the user's environment. So calling functions like Path.GetTempPath() points to \windows\temp instead of the user's. Also when attempting to run Outlook 2007+ via MAPI calls (to add attachments) it reports form errors due to, I think, the temp folder location. Is there a way to "reload" a profile or atleast get your environment vars within the Impersonated application? The only ideas I've had so far is to rebuild the vars directly from the registry, but I want to avoid this since it's a hack around (avoiding implementation details and all that). Or making a stub program that Redmon calls which then properly Run As User with full profile the custom application. Any other items or tricks?

  • Android Scaled Drawing to ImageView

    - by user329999
    Newbie question, so there's probably a simple answer to this problem. I'm drawing some simple shapes using canvas.drawCircle(), canvas.drawLine() etc. I originally copied the code from: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/DrawPoints.html Which extends a View and draws directly to a canvas. It doesn't load a pre-drawn bitmap because I need my application to turn data into a drawing and the user will enter the data. My changes work, but the drawing is too small (or big) and doesn't fill the screen using all the available screen. Ideally I'd rather use something like an ImageView in .XML like so: If that's possible. The documentation seems to imply that I want to set the scaleType as shown in the above .XML which seems like the simple way to do this. If using an ImageView in .XML is a good idea, then I'm lost on how to draw to the ImageView and could use some guidance on doing that task. If that won't work, then I'll need to do some more thinking about how to get my drawing scaled on the screen and basically I'm lazy and would rather have Android do the work for me. Feel free to suggest some other way that's completely different is this is the wrong solution path. :) Thanks.

  • How to handle value types when embedding IronPython in C#?

    - by kloffy
    There is a well known issue when it comes to using .NET value types in IronPython. This has recently caused me a headache when trying to use Python as an embedded scripting language in C#. The problem can be summed up as follows: Given a C# struct such as: struct Vector { public float x; public float y; } And a C# class such as: class Object { public Vector position; } The following will happen in IronPython: obj = Object() print obj.position.x # prints ‘0’ obj.position.x = 1 print obj.position.x # still prints ‘0’ As the article states, this means that value types are mostly immutable. However, this is a problem as I was planning on using a vector library that is implemented as seen above. Are there any workarounds for working with existing libraries that rely on value types? Modifying the library would be the very last resort, but I'd rather avoid that.
