• "Genie" animation effect in XAML

  - by ScottCate

  What would the XAML look like to create a Genie animation effect? Take an object of any size/shape, and "Genie" it to another Minimized location. Kind of like the OSX window minimize. Maybe even a little fancier through a smoke-like effect where the path is more switch back, instead of a simple funnel (if that makes any sense). I'm guessing that there is some sort of Path that could be drawn, and the shape could move and transform along that path. Just a wild guess. Thanks for your ideas.

• How to convert a DOM node list to an array in Javascript?

  - by Guss

  I have a Javascript function that accepts a list of HTML nodes, but it expects a Javascript array (it runs some Array methods on that) and I want to feed it the output of Document.getElementsByTagName that returns a DOM node list. Initially I thought of using something simple like: Array.prototype.slice.call(list,0) And that works fine in all browsers, except of course Internet Explorer which returns the error "JScript object expected", as apparently the DOM node list returned by Document.getElement* methods is not a JScript object enough to be the target of a function call. Caveats: I don't mind writing Internet Explorer specific code, but I'm not allowed to use any Javascript libraries such as JQuery because I'm writing a widget to be embedded into 3rd party web site, and I cannot load external libraries that will create conflict for the clients. My last ditch effort is to iterate over the DOM node list and create an array myself, but is there a nicer way to do that?

• Iterative / Additive MD5

  - by Andrew Robinson

  I need to generate a checksum over a dictionary. Keys and Values. Is there any simple way to accomplish this in an iterative way. foreach(var item in dic.Keys) checksum += checksum(dic[item]) + checksum(item); In this case, keys and values could be converted to strings, concatinated and then a single checksum applied over these but is there a better way? Ideally MD5 but other options could work. Using this to validate data that is passed over a couple of storage methods. The checksum is then encrypted along with some other information (using AES) so I am not horribly worried about an ideal, unbreakable checksum.

• Custom Java events with listeners vs. a JMS based implementation?

  - by Joe Dean

  My application requires events to be fired based on some specific activities that happen. I'm trying to determine if I should create my own event handling system using the Java EventObject with custom listeners similar to Java AWT Or should I use a JMS implementation? I was considering either apache's Qpid or ActiveMQ solution. I'm exploring these options at the moment and was wondering if anyone has experience with Qpid or ActiveMQ and can offer some advise (e.g., pros, cons to consider, etc) Also, if anyone has any suggestions for building a simple event handling system... if it's even worth while to consider this over a JMS based solution.

• Simulating Ajax failures for QA testing

  - by womp

  Our first ASP.Net MVC/jQuery product is about to go to QA, and we're looking for a way for our QA guys to easily be able to simulate bad Ajax requests (without modifying the application code). A typical integration/UI test plan might be: Load page, click button "DoStuff" "DoStuff" fails Attempt button "DoStuff" again "DoStuff" succeeds Verify application state This is a simple test case - there will be cases with multiple failures and successes interspersed. Aside from "unplug your network cable" I'm looking for an easy way for our guys to simulate intermittent bad server responses. I'm open to any ideas so I won't go into too many details about our application setup or dependencies. How have you handled this?

• Domain-driven design with Zend

  - by mik

  This question is a continuation of my previous question here http://stackoverflow.com/questions/2122850/zend-models-architecture (big thanks to Bill Karwin). I've made some reading including this article http://weierophinney.net/matthew/archives/202-Model-Infrastructure.html and this question http://stackoverflow.com/questions/373054/how-to-properly-create-domain-using-zend-framework Now I understand, what domain driven design is. But examples are still very simple and poor. They are based on one table and one model. Now, my question is: do they use Domain Model Design in real-world PHP projects? I've been looking for some good documentation about this, but I haven't found anything good enough, that explains how to manage several tables and transfer them to Domain Objects. As long as I know, there is Hibernate library, that has this features in Java, but what should I use in PHP (Zend Framework)?

• What exactly is a Monad?

  - by WeNeedAnswers

  Can someone please explain to me what a Monad is. I think I grasp Monoids and I grasp that they basically control the input of state into a system. I just look at the text in Haskell and glaze over. A simple example in python would be great. My current understanding is that a Monoid is a procedural piece of code that needs to be read from top to bottom in sequence with the output being the input for the function. I think that I may even got that wrong, but hey I am here to learn.

• Regex pattern for searches with include and exclude

  - by alex-kravchenko-zmeyp

  I am working on a Regex pattern for searches that should allow optional '+' sign to include in the search and '-' sign to exclude from the search. For example: +apple orange -peach should search for apples and oranges and not for peaches. Also the pattern should allow for phrases in double quotes mixed with single words, for example: "red apple" -"black grape" +orange - you get the idea, same as most of the internet searches. So I am running 2 regular expressions, first to pick all the negatives, which is simple because '-' is required: (?<=[\-]"?)((?<=")(?<exclude>[^"]+)|(?<exclude>[^\s,\+\-"]+)) And second to pick positives, and it is a little more complex because '+' is optional: ((?<=[\+\s]")(?<include>[^\s"\+\-][^"]+))|(?<include>(?<![\-\w]"?)([\w][^,\s\-\+]+))(?<!") Positive search is where I am having a problem, it works fine when I run it in RegexBuddy but when I try in .Net the pattern picks up second word from negative criteria, for example in -"black grape" it picks up word 'grape' even though it ends with double quote. Any suggestions?

• ASP.NET MVC User authentication - why it should be so sophisticated?

  - by Serge

  Hello guys, I'm trying to use ASP.NET MVC to my new project and have been expected that the user authentication should be rather simple there. My goal is to have a separate user database table in my main database. I thought that the SqlTableProfileProvider should be the solution. So I added the corresponding table into my database and changed the web.config file. But it seems no matter what I change there, my web application still using the default authentication (via ASPNETDB.mdf file). What could be the problem? (my web.config file beginning is:)

• Java singleton VO class implementing serializable, having default values using getter methods

  - by user309281

  Hi All I have a J2SE application having user threads running in a separate JVM outside JBOSS server. During startup, J2SE invokes a EJB inside jboss, by passing a new object(singleton) of simple JAVA VO class having getter/setter methods. {The VO class is a singleton and implements serialiable(as mandated by EJB)}. EJB receives the object, reads all db configuration and uses the setter methods of new object to set all the values. It then returns back this updated object back to J2SE in the same remote call. After J2SE receives the object(singleton/serializable), if i invoke getter methods, I could see only default values set during object creation before EJB call, and not the values set by the EJB. Kindly throw some light on, why the received object from EJB does not see any updated values and how to rectify this. I believe it got to do with object initialization during deserialization. And i tried overriding readResolve() in the VO class, but of no help. With Regards, Krishna

• Delphi Clientdataset Lookup/Aggregate

  - by TheRoadrunner

  Hi, I need a little help with ClientDatasets in Delphi. What I want to achieve is a grid showing customers, where one of the columns shows the number of orders for each customer. I put a ClientDataset on a form and load Customers.xml from Delphi demo-data. Another ClienDataset is loaded with orders.xml. Relatively simple, I can define an aggregate on the orders CDS showing the total amount per customer (or the count). (See Cary Jensens article on this: http://edn.embarcadero.com/article/29272) The problem is getting this aggregate result from orders dataset into the customer dataset. It is kind of an reverse lookup, since there is a 1-n relationship between customers and orders, not an n-1 as normally in lookup scenarios. Any ideas ? Søren

• Visual Studio 2005 - VC++ compiler C1001 on Windows 7

  - by Fritz H

  When I try to build a simple "Hello World" C++ app on Windows 7 Beta, using Visual Studio 2005 (VC++2005) I get a rather generic error C1001 error (Internal compiler error) The compiler seems to just crash, and Windows pops up its (un)helpful This program has stopped working dialog. The file it complains about is mcp1.cpp. Has anyone come across this before? Cheers, Fritz EDIT: The code is: #include <iostream> int main(int argc, char** argv) { std::cout << "Hello!"; return 0; } EDIT 2: I have installed SP1 as well as SP1 for Vista. VS popped up a warning saying it needs SP1 for Vista, but installing it makes no difference. No ideas about what I can possibly do to fix this?

• Socket read() hangs for a while when there is no data to read.

  - by janesconference

  Hi' I'm writing a simple http port forwarder. I read data from port 80, and pass the data to my lighttpd server, on port 8080. As long as I write() data on the socket on port 8080 (forwarding the request) there's no problem, but when I read() data from that socket (forwarding the response), the last read() hangs a lot (about 1 or 2 seconds) before realizing there's no more data and returning 0. I tried to set the socket to non-blocking, but this doesn't work, as sometimes it returns EWOULDBLOCKING even if there's some data left (lighttpd + cgi can be quite slow). I tried to set a timeout with select(), but, as above, a slow cgi could timeout the socket when there's actually some data to transmit. How would you do?

• IIS Virtual Directory/Application & Forms authentication

  - by user216194

  I've setup and deployed a simple forms authentication website with membership using .NET 4. I've created a virtual directory (now converted to "Application") in IIS7 and setup the web.config file in the virtual directory as follows: <system.webServer> <directoryBrowse enabled="true" /> </system.webServer> Great! I browse to the virtual directory: ../mydomain/books/ and I'm automatically redirected to the login page specified by web.config in my root directory and the url path is placed as follows: ../Account/Login.aspx?ReturnUrl=%2fbooks At this point, I login succesfully, but I am not redirected anywhere, and when I manually return to the directory, ../books, I'm sent back to the login page, where I'm already logged in? So I'm confused about what my problem is! I should be successfully authenticated, and than redirected back to the directory, or at the very least be able to view it manually after I log in right?

• starting subactivity for the second time causes java.lang.OutOfMemoryError

  - by Zacherl

  Hi there, I am developing a simple app which does a little bit of image-processing. It's divided in two activities; the main one with some display elements and the second one which is used to capture images off the phone's camera. To discribe my problem: I start the app, capture an image (by starting a new Intent with the subactivity) and all data is displayed correctly. If I capture another image after this, I run in an java.lang.OutOfMemoryError - bitmap size exceeds VM budget I dont store the captured bitmap, in the second activity I just extract some data from it and pass it to the main-activity; finishing (finish()) the sub-activity afterwards. I really dont know what I can do about it. Thanks in advance! greetings, Zacherl PS: It is my first approach to android, so I apologize for any stupid beginner error I did; if someone needs any further information, I would be happy to provide it.

• How to read a file with variable multi-row data in Python

  - by dr.bunsen

  I have a file that is about 100Mb that looks like this: #meta data 1 skadjflaskdjfasljdfalskdjfl sdkfjhasdlkgjhsdlkjghlaskdj asdhfk #meta data 2 jflaksdjflaksjdflkjasdlfjas ldaksjflkdsajlkdfj #meta data 3 alsdkjflasdjkfglalaskdjf This file contains one row of meta data that corresponds to several, variable length data containing only alpha-numeric characters. What is the best way to read this data into a simple list like this: data = [[#meta data 1, skadjflaskdjfasljdfalskdjflsdkfjhasdlkgjhsdlkjghlaskdjasdhfk], [#meta data 2, jflaksdjflaksjdflkjasdlfjasldaksjflkdsajlkdfj], [#meta data 3, alsdkjflasdjkfglalaskdjf]] My initial idea was to use the read() method to read the whole file into memory and then use regular expressions to parse the data into the desired format. Is there a better more pythonic way? All metadata lines start with an octothorpe and all data lines are all alpha-numeric. Thanks!

• A quick over view of facebook's db?

  - by Matt

  Hey guys I find it hard to believe that Facebook uses simple sql, surely it would use some other method but lets assume for now it does use sql how would the code assimilating the 'wall' work? Lets say that there is three tables (just for the example) Friends: id (entry key) - uid(your id) - fid (your mates' id) Wall:id (entry key) - username - comment - time - commentcount comments: id (entry key) - wid (wall id (original comment)) - reply - time Lets forget about the like part and report etc, as well as mod things (ip, ban etc.) How would this work? Select wall.id, wall.username, wall.comment, wall.time, wall.commentcount, comments.wid, comments.reply, comments.time FROM wall inner join comments ON wall.id=comments.wid ORDER BY wall.time; That's your own wall but how do they get friend's? A heap of unions?

• Selecting a radio button when a dropdown value changes

  - by Tim F.

  My setup is something like this: radiobutton1 - selection1 radiobutton2 - selection2 textinput1 I want radiobutton1 to be selected whenever selection1 is changed, and I want radiobutton2 to be selected whenever either selection2 or textinput1 is changed. There has to be a simple javascript solution here... I just can't find it. Here's my actual code ("$semopt" is a string holding the html code for the options on the first selection input): <input type='radio' name='semester' value='existing'/>Existing semester: <select name='sem_id'">$semopt </select><br/> <input type='radio' name='semester' value='new'/>New Semester: <select name='sem_name'"> <option value='Fall'>Fall</option> <option value='Spring'>Spring</option> </select> <input name='sem_year' value='$thisyear' size='5'"/><br/>

• Best library to parse HTML with Python 3 and example?

  - by TMC

  I'm new to Python completely and am using Python 3.1 on Windows (pywin). I need to parse some HTML, to essentially extra values between specific HTML tags and am confused at my array of options, and everything I find is suited for Python 2.x. I've read raves about Beautiful Soup, HTML5Lib and lxml, but I cannot figure out how to install any of these on Windows. Questions: What HTML parser do you recommend? How do I install it? Do you have a simple example on how to use the recommended library to snag HTML from a specific URL and return the value out of say something like this: fooLink (say we want to return "/blahblah")

• Servlet request getparameter's performance

  - by Bob

  Hi, I noticed that my app is very slow sometimes, so I've done some tests. It's a very simple web app. One servlet gets some parameters than stores them. Everything's fine except one thing. It takes too long to get a parameter for the first time. It doesn't matter which parameter I try to get, but for the first time it is very slow. The strange thing is this doesn't happen always. Sometimes getting a parameter for the first time is not slow. My code looks like this request.getParameter("paramName"); request.getParameter("paramName2"); request.getParameter("paramName3"); Getting "paramName" is slow. Getting the others is very fast. By slow I mean : 200-800 millisec By very fast I mean: ~0 millisec (in the code snippet, I didn't write the performance test, but I'm using System.currentTimeMillis())

• Android insert into sqlite database

  - by Josh

  I know there is probably a simple thing I'm missing, but I've been beating my head against the wall for the past hour or two. I have a database for the Android application I'm currently working on (Android v1.6) and I just want to insert a single record into a database table. My code looks like the following: //Save information to my table sql = "INSERT INTO table1 (field1, field2, field3) " + "VALUES (" + field_one + ", " + field_two + ")"; Log.v("Test Saving", sql); myDataBase.rawQuery(sql, null); the myDataBase variable is a SQLiteDatabase object that can select data fine from another table in the schema. The saving appears to work fine (no errors in LogCat) but when I copy the database from the device and open it in sqlite browser the new record isn't there. I also tried manually running the query in sqlite browser and that works fine. The table schema for table1 is _id, field1, field2, field3. Any help would be greatly appreciated. Thanks!

• [Android] accessing another Activity's preferences

  - by Raffaele

  I have a Login Activity which stores credentials in its own SharedPreferences; then I added two getters for reading them, something like public String getUsername() { return getPreferences(MODE_PRIVATE).getString("#username", null); } but this throws a NPE when I call it like this String mUser = (new Login()).getUsername(); It seems that the Activity cannot read its preferences after a simple contructor call, as if it were in some uncompleted state. I read lots of related topics, but wasn't able to find a solution. Basically, I need to share these credentials among activities in my application

• Linking Libraries in Xcode

  Hey all, I'm using a powerbook (osx 10.5) and recently downloaded and installed FFTW 3.2 (link text). I've been able to compile and run some simple programs based on the online tutorial using the terminal: g++ main.cpp -lfftw3 -lm however, I can't get the same program to compile in Xcode. I get a linking error, "symbol(s) not found". There is a file called libfftw3.a in /usr/local/lib. How can this be linked? Furthermore, apparently the libraries have to be linked in a particular order, i.e. see: link text thanks for any help
