  • AsyncBridge? Async on .NET 4.0 using VS11

    - by Alex.Davies
    I've just found something quite cool. It's a code snippet that lets you use the real VS 11 C#5 compiler to write code that uses the async and await keywords, but to target .NET 4.0. It was published by Daniel Grunwald (from SharpDevelop).That means I can stop using the Async CTP for VS2010, which is not at all supported anymore, and a pain to install if you have windows updates turned on. Obviously I couldn't ask all my users to install .NET 4.5 beta, but .NET Demon is a VS 2010 extension, so we already have .NET 4.0. At the time of writing, VS11 is in beta still, but hopefully it's stable enough for my team to use!I would have written the code myself, but I had the wrong impression that the C# 5 beta compiler only looked in mscorlib for the helper classes it needs to implement async methods. Turns out you can provide them yourself. You can get the code here: https://gist.github.com/1961087You just add it to your project, and the compiler will apparently pick it up and use it to implement async/await. I'm at my parents' place for Easter without access to a machine with VS 11 to try it out. Let me know whether you get it to work!This reminds me of LINQBridge, which let us use C# 3 LINQ, but only require .NET 2. We should stick up a webpage to explain, with a nice easy dll, put it in nuget, and call it AsyncBridge.If you were really enthusiastic, you could re-implement the skeleton of the Task Parallel Library against .NET 2 to use async/await without even requiring .NET 4. Our usage stats suggest that practically everyone that uses Red Gate tools already has .NET 4 installed though, so I don't think I'll go to the effort.

  • Android passing an arraylist back to parent activity

    - by Nicklas O
    Hi there. I've been searching for a simple example of this with no luck. In my android application I have two activities: 1. The main activity which is launched at startup 2. A second activity which is launched by pressing a button on the main activty. When the second activity is finished (by pressing a button) I want it to send back an ArrayList of type MyObject to the main activity and close itself, which the main activity can then do whatever with it. How would I go about achieving this? I have been trying a few things but it is crashing my application when I start the second activity. When the user presses button to launch second activity: Intent i = new Intent(MainActivity.this, secondactivity.class); startActivityForResult(i, 1); The array which is bundled back after pressing a button on the second activity: Intent intent= getIntent(); Bundle b = new Bundle(); b.putParcelableArrayList("myarraylist", mylist); intent.putExtras(b); setResult(RESULT_OK, intent); finish(); And finally a listener on the main activity (although I'm not sure of 100% when this code launches...) protected void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if(resultCode==RESULT_OK && requestCode==1){ Bundle extras = data.getExtras(); final ArrayList<MyObject> mylist = extras.getParcelableArrayList("myarraylist"); Toast.makeText(MainActivity.this, mylist.get(0).getName(), Toast.LENGTH_SHORT).show(); } } Any ideas where I am going wrong? The onActivityResult() seems to be crashing my application. EDIT: This is my class MyObject, its called plan and has a name and an id import android.os.Parcel; import android.os.Parcelable; public class Plan implements Parcelable{ private String name; private String id; public Plan(){ } public Plan(String name, String id){ this.name = name; this.id = id; } public String getName(){ return name; } public void setName(String name){ this.name = name; } public String getId(){ return id; } public void setId(String id){ this.id = id; } public String toString(){ return "Plan ID: " + id + " Plan Name: " + name; } @Override public int describeContents() { // TODO Auto-generated method stub return 0; } @Override public void writeToParcel(Parcel dest, int flags) { dest.writeString(id); dest.writeString(name); } public static final Parcelable.Creator<Plan> CREATOR = new Parcelable.Creator<Plan>() { public Plan createFromParcel(Parcel in) { return new Plan(); } @Override public Plan[] newArray(int size) { // TODO Auto-generated method stub return new Plan[size]; } }; } This is my logcat E/AndroidRuntime( 293): java.lang.RuntimeException: Unable to instantiate activ ity ComponentInfo{com.daniel.android.groupproject/com.me.android.projec t.secondactivity}: java.lang.NullPointerException E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2417) E/AndroidRuntime( 293): at android.app.ActivityThread.handleLaunchActivi ty(ActivityThread.java:2512) E/AndroidRuntime( 293): at android.app.ActivityThread.access$2200(Activi tyThread.java:119) E/AndroidRuntime( 293): at android.app.ActivityThread$H.handleMessage(Ac tivityThread.java:1863) E/AndroidRuntime( 293): at android.os.Handler.dispatchMessage(Handler.ja va:99) E/AndroidRuntime( 293): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 293): at android.app.ActivityThread.main(ActivityThrea d.java:4363) E/AndroidRuntime( 293): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 293): at java.lang.reflect.Method.invoke(Method.java:5 21) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit$MethodAndA rgsCaller.run(ZygoteInit.java:860) E/AndroidRuntime( 293): at com.android.internal.os.ZygoteInit.main(Zygot eInit.java:618) E/AndroidRuntime( 293): at dalvik.system.NativeStart.main(Native Method) E/AndroidRuntime( 293): Caused by: java.lang.NullPointerException E/AndroidRuntime( 293): at com.daniel.android.groupproject.login.<init>( login.java:51) E/AndroidRuntime( 293): at java.lang.Class.newInstanceImpl(Native Method ) E/AndroidRuntime( 293): at java.lang.Class.newInstance(Class.java:1479) E/AndroidRuntime( 293): at android.app.Instrumentation.newActivity(Instr umentation.java:1021) E/AndroidRuntime( 293): at android.app.ActivityThread.performLaunchActiv ity(ActivityThread.java:2409) E/AndroidRuntime( 293): ... 11 more

  • Generate authenticated CMSEnvelopedData Messages with bouncycastle

    - by levinalex
    I am trying to encrypt data with a password and store it inside a ASN.1 encoded CMS message (using C# and BouncyCastle 1.4) The code I have seems to have two problems: the data does not seem to be signed with a HMAC, so when I tamper with the encodedData (by enabling the commented out line), the decryption still succeeds. when I decrypt the data I have tampered with, I get beck corrupted plain text. However only a two blocks of plaintext data are corrupted. This seems to suggest that the encryption does not actually use CBC mode. (edit: disregard the second point, this is exactly how CBC is supposed to work) This is what I am testing with: public void TestMethod1() { byte[] data = new byte[1024]; // plaintext: a list of zeroes CmsEnvelopedDataGenerator generator = new CmsEnvelopedDataGenerator(); CmsPbeKey encryptionKey = new Pkcs5Scheme2PbeKey("foo", new byte[] { 1, 2, 3 }, 2048); generator.AddPasswordRecipient(encryptionKey, CmsEnvelopedDataGenerator.Aes256Cbc); CmsProcessableByteArray cmsByteArray = new CmsProcessableByteArray(data); CmsEnvelopedData envelopeData = generator.Generate(cmsByteArray, CmsEnvelopedDataGenerator.Aes256Cbc); byte[] encodedData = envelopeData.GetEncoded(); // encodedData[500] = 10; // tamper with the data RecipientID recipientID = new RecipientID(); CmsEnvelopedData decodedEnvelopeData = new CmsEnvelopedData(encodedData); RecipientInformation recipient = decodedEnvelopeData.GetRecipientInfos().GetFirstRecipient(recipientID); byte[] data2 = recipient.GetContent(encryptionKey); CollectionAssert.AreEqual(data, data2); } What am I doing wrong? What would be the correct way to write this?

  • Just a general THANK YOU to EVERYONE. [closed]

    - by ajax81
    Hi All, I really just wanted to thank everybody that participates in the stackoverflow community. On more than one occasion, your minds have saved me from soul-eating project managers and career-ending deadlines. The commendable awareness exhibited by contributors that their answers are studied/used as learning material by millions of developers all over the world has created a regulated trust that seemingly keeps the nonsense (and egos) at the bottom of the barrel and out of the way. As an up-and-coming developer with so much to learn, I am grateful for each and every one of their patient contributions. I wish I could come up with a catchy/funny sign-off that makes everybody feel good, but I lack the funny bone that so many of the people on this site seem to have been born with. Instead, I can only leave my gratitude and a promise that as long as the community stays this great, I'll stay an avid reader...and one day be experienced enough to carry the torch of contribution. Sincerely, Daniel the Intern

  • Powerpoint Add-In: Add a Button to PPT to SyntaxHighlight a Textbox

    - by Tigraine
    Hi Guys, I am trying to write an Add-In to Powerpoint that does basically one thing: Give users a Button somewhere to click, once they click on it the currently selected TextField should get syntax highlighted. The Syntax highlighting part is easy, I'm just having a real hard time finding some good information on how to successfully interact with Powerpoint from code. There are some MSDN articles highlighting how to add controls on document start or AddSlide, but no good information on how to extend the UI. Has anyone had some experience in this field and could point me to some resource that may help? Also, I am running Powerpoint 2007 while my customer may end up running PPT2003. How is the backwards compatibility of the Add-ins? greetings Daniel

  • How can I effectively test against the Windows API?

    - by Billy ONeal
    I'm still having issues justifying TDD to myself. As I have mentioned in other questions, 90% of the code I write does absolutely nothing but Call some Windows API functions and Print out the data returned from said functions. The time spent coming up with the fake data that the code needs to process under TDD is incredible -- I literally spend 5 times as much time coming up with the example data as I would spend just writing application code. Part of this problem is that often I'm programming against APIs with which I have little experience, which forces me to write small applications that show me how the real API behaves so that I can write effective fakes/mocks on top of that API. Writing implementation first is the opposite of TDD, but in this case it is unavoidable: I do not know how the real API behaves, so how on earth am I going to be able to create a fake implementation of the API without playing with it? I have read several books on the subject, including Kent Beck's Test Driven Development, By Example, and Michael Feathers' Working Effectively with Legacy Code, which seem to be gospel for TDD fanatics. Feathers' book comes close in the way it describes breaking out dependencies, but even then, the examples provided have one thing in common: The program under test obtains input from other parts of the program under test. My programs do not follow that pattern. Instead, the only input to the program itself is the system upon which it runs. How can one effectively employ TDD on such a project?

  • Fastest way to list all primes below N in python

    - by jbochi
    This is the best algorithm I could come up with after struggling with a couple of Project Euler's questions. def get_primes(n): numbers = set(range(n, 1, -1)) primes = [] while numbers: p = numbers.pop() primes.append(p) numbers.difference_update(set(range(p*2, n+1, p))) return primes >>> timeit.Timer(stmt='get_primes.get_primes(1000000)', setup='import get_primes').timeit(1) 1.1499958793645562 Can it be made even faster? EDIT: This code has a flaw: Since numbers is an unordered set, there is no guarantee that numbers.pop() will remove the lowest number from the set. Nevertheless, it works (at least for me) for some input numbers: >>> sum(get_primes(2000000)) 142913828922L #That's the correct sum of all numbers below 2 million >>> 529 in get_primes(1000) False >>> 529 in get_primes(530) True EDIT: The rank so far (pure python, no external sources, all primes below 1 million): Sundaram's Sieve implementation by myself: 327ms Daniel's Sieve: 435ms Alex's recipe from Cookbok: 710ms EDIT: ~unutbu is leading the race.

  • In Clojure - How do I access keys in a vector of structs

    - by Nick
    I have the following vector of structs: (defstruct #^{:doc "Basic structure for book information."} book :title :authors :price) (def #^{:doc "The top ten Amazon best sellers on 16 Mar 2010."} best-sellers [(struct book "The Big Short" ["Michael Lewis"] 15.09) (struct book "The Help" ["Kathryn Stockett"] 9.50) (struct book "Change Your Prain, Change Your Body" ["Daniel G. Amen M.D."] 14.29) (struct book "Food Rules" ["Michael Pollan"] 5.00) (struct book "Courage and Consequence" ["Karl Rove"] 16.50) (struct book "A Patriot's History of the United States" ["Larry Schweikart","Michael Allen"] 12.00) (struct book "The 48 Laws of Power" ["Robert Greene"] 11.00) (struct book "The Five Thousand Year Leap" ["W. Cleon Skousen","James Michael Pratt","Carlos L Packard","Evan Frederickson"] 10.97) (struct book "Chelsea Chelsea Bang Bang" ["Chelsea Handler"] 14.03) (struct book "The Kind Diet" ["Alicia Silverstone","Neal D. Barnard M.D."] 16.00)]) I would like to sum the prices of all the books in the vector. What I have is the following: (defn get-price "Same as print-book but handling multiple authors on a single book" [ {:keys [title authors price]} ] price) Then I: (reduce + (map get-price best-sellers)) Is there a way of doing this without mapping the "get-price" function over the vector? Or is there an idiomatic way of approaching this problem?

  • JDBC character encoding

    - by wheelie
    Hi there, I have a Java Web application using GlassFish 3, JSF2.0 (facelets) and JPA (EclipseLink) on MySQL (URL: jdbc:mysql://localhost:3306/administer). The problem I'm facing is that if I'm saving entities to the database with the update() method, String data loses integrity; '?' is shown instead of some characters. The server, pages and database is/are configured to use UTF-8. After I post form data, the next page shows the data correctly. Furthermore it "seems" in debug that the String property of the current entity stores the correct value too. Dunno if NetBeans debug can be trusted; might be that it decodes correctly, however it's incorrect. Any help would be appreciated, thanks in advance! Daniel

  • All possible values of int from the smallest to the largest, using Java.

    - by Totophil
    Write a program to print out all possible values of int data type from the smallest to the largest, using Java. Some notable solutions as of 8th of May 2009, 10:44 GMT: 1) Daniel Lew was the first to post correctly working code. 2) Kris has provided the simplest solution for the given problem. 3) Tom Hawtin - tackline, came up arguably with the most elegant solution. 4) mmyers pointed out that printing is likely to become a bottleneck and can be improved through buffering. 5) Jay's brute force approach is notable since, besides defying the core point of programming, the resulting source code takes about 128 GB and will blow compiler limits. As a side note I believe that the answers do demonstrate that it could be a good interview question, as long as the emphasis is not on the ability to remember trivia about the data type overflow and its implications (that can be easily spotted during unit testing), or the way of obtaining MAX and MIN limits (can easily be looked up in the documentation) but rather on the analysis of various ways of dealing with the problem.

  • Qt4 book says "make release", reality disagrees

    - by DarenW
    Writing some simple Qt4 demos depending the book by Daniel Molkentin. In that book, it says you build the release or debug versions of your app with "make release" or "make debug". In real life, these give errors. Only bare naked "make" works. I assume something has changed between the version of Qt4 used in the book and the version I'm using, qt4.6.2. So what is the proper way to determine whether to make release or debug? (And why can't google find any updates or errata for this book relating to this?)

I need the dll to be shipped within the new application - but understandably I do not want the dll file to be used for foreign apps. That's why I need the custom dll to be somehow compiled within the new application. Currently the dll is copied into the application directory. Any ideas? Should be trivial imho.

  • What are Code Smells? What is the best way to correct them?

    - by Rob Cooper
    OK, so I know what a code smell is, and the Wikipedia Article is pretty clear in its definition: In computer programming, code smell is any symptom in the source code of a computer program that indicates something may be wrong. It generally indicates that the code should be refactored or the overall design should be reexamined. The term appears to have been coined by Kent Beck on WardsWiki. Usage of the term increased after it was featured in Refactoring. Improving the Design of Existing Code. I know it also provides a list of common code smells. But I thought it would be great if we could get clear list of not only what code smells there are, but also how to correct them. Some Rules Now, this is going to be a little subjective in that there are differences to languages, programming style etc. So lets lay down some ground rules: ** ONE SMELL PER ANSWER PLEASE! & ADVISE ON HOW TO CORRECT! ** See this answer for a good display of what this thread should be! DO NOT downmod if a smell doesn't apply to your language or development methodology We are all different. DO NOT just quickly smash in as many as you can think of Think about the smells you want to list and get a good idea down on how to work around. DO downmod answers that just look rushed For example "dupe code - remove dupe code". Let's makes it useful (e.g. Duplicate Code - Refactor into separate methods or even classes, use these links for help on these common.. etc. etc.). DO upmod answers that you would add yourself If you wish to expand, then answer with your thoughts linking to the original answer (if it's detailed) or comment if its a minor point. DO format your answers! Help others to be able to read it, use code snippets, headings and markup to make key points stand out!

    What would be the best approach to reverse a large text file that is uploaded asynchronously to a servlet that reverses this file in a scalable and efficient way? text file can be massive (gigabytes long) can assume mulitple server/clustered environment to do this in a distributed manner. open source libraries are encouraged to consider I was thinking of using Java NIO to treat file as an array on disk (so that I don't have to treat the file as a string buffer in memory). Also, I am thinking of using MapReduce to break up the file and process it in separate machines. Any input is appreciated. Thanks. Daniel

  • Strange problem when converting RGB to HSV

    - by zaplec
    Hi, I made a small RGB to HSV converter algorithm with C. It seems to work pretty well, but there is one strange problem: If I first convert i.e. a 800x600 picture into HSV map and then back to RGB map without doing any changes in the values, I get some pixels that are convertet incorrectly. Then if I try to convert those misbehaving single pixels alone to and back, they're converted correctly. Any idea what could be the problem? I'm using Daniel Karlings PNGLite to open that PNG file. Here are the source code of my main.c, rgbtohsv.c and rgbtohsv.h rgbToHsv.h rgbToHsv.c pngmain.c I linked pngmain only that if somebody wants to test and run this on his own system. -zaplec

  • Make XStream ignore one specific private variable

    - by Tigraine
    Hi guys, I have a little problem with a class I am currently writing a save function for. I'm using XStream (com.thoughtworks.xstream) to serialize a class to XML using the DOMDriver. The class looks like this: public class World { private Configuration config; public World(Configuration config) { this.config = config; } } So, the issue here is that I do not want to serialize Configuration when serializing world, rather I'd like to give XStream a preconstructed Configuration instance when calling fromXml(). Problem here is mainly class design, Configuration holds a private reference to the GUI classes and therefore serializing Configuration means serializing the whole application completely with GUI etc.. And that's kind of bad. Is there a way to instruct XStream to not serialize the private field config, and upon load supply XStream with a configuration instance to use? greetings Daniel

But i have a problem here is code import java.io.BufferedReader; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.InputStreamReader; import java.net.URL; import java.net.URLConnection; import java.net.URLEncoder; import java.util.ArrayList; import java.util.Enumeration; import java.util.Hashtable; import java.util.List; import org.json.JSONArray; import org.json.JSONObject; import com.yahoo.search.WebSearchResult; /** * Simple Search using Google ajax Web Services * * @author Daniel Jones Copyright 2006 Daniel Jones Licensed under BSD open * source license http://www.opensource.org/licenses/bsd-license.php */ public class GoogleSearchEngine extends Thread { private String queryString; private int maxResult; private ArrayList<String> resultGoogleArrayList = null; public ArrayList<String> getResultGoogleArrayList() { return resultGoogleArrayList; } public void setResultGoogleArrayList(ArrayList<String> resultGoogleArrayList) { this.resultGoogleArrayList = resultGoogleArrayList; } public String getQueryString() { return queryString; } public void setQueryString(String queryString) { this.queryString = queryString; } public int getMaxResult() { return maxResult; } public void setMaxResult(int maxResult) { this.maxResult = maxResult; } // Put your website here public final static String HTTP_REFERER = "http://www.example.com/"; public static ArrayList<String> makeQuery(String query, int maxResult) { ArrayList<String> finalArray = new ArrayList<String>(); ArrayList<String> returnArray = new ArrayList<String>(); try { query = URLEncoder.encode(query, "UTF-8"); int i = 0; String line = ""; StringBuilder builder = new StringBuilder(); while (true) { // Call GoogleAjaxAPI to submit the query URL url = new URL("http://ajax.googleapis.com/ajax/services/search/web?start=" + i + "&rsz=large&v=1.0&q=" + query); URLConnection connection = url.openConnection(); if (connection == null) { break; } // Value i to stop while or Max result if (i >= maxResult) { break; } connection.addRequestProperty("Referer", HTTP_REFERER); BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8")); while ((line = reader.readLine()) != null) { builder.append(line); } String response = builder.toString(); JSONObject json = new JSONObject(response); JSONArray ja = json.getJSONObject("responseData").getJSONArray("results"); for (int j = 0; j < ja.length(); j++) { try { JSONObject k = ja.getJSONObject(j); // Break string into 2 parts: URL and Title by <br> returnArray.add(k.getString("url") + "<br>" + k.getString("titleNoFormatting")); } catch (Exception e) { e.printStackTrace(); } } i += 8; } // Remove objects that is over the max number result required if (returnArray.size() > maxResult) { for (int k=0; k<maxResult; k++){ finalArray.add(returnArray.get(k)); } } else return returnArray; return finalArray; } catch (Exception e) { e.printStackTrace(); } return null; } @Override public void run() { // TODO Auto-generated method stub //super.run(); this.resultGoogleArrayList = GoogleSearchEngine.makeQuery(queryString, maxResult); System.out.println("Code run here "); } public static void main(String[] args) { Thread test = new GoogleSearchEngine(); ((GoogleSearchEngine) test).setQueryString("data "); ((GoogleSearchEngine) test).setMaxResult(10); test.start(); ArrayList<String> returnGoogleArrayList = null; returnGoogleArrayList = ((GoogleSearchEngine) test).getResultGoogleArrayList(); System.out.print("contents of al:" + returnGoogleArrayList); } } when i run it, it can run into run method but it don't excute make query methor and return null array. when i do't use Thread it can nomal . Can you give me the reason why ? or give a sulution Thanks
