• Rhino ServiceBus: Sagas with multiple messages

  - by illdev

  I have a saga that can handle multiple messages like so: public class OrderSaga : ISaga<Order> , InitiatedBy<StartOrderSaga> , Orchestrates<CancelOrder> , Orchestrates<PaymentForOrderReceived> , Orchestrates<CheckOrderWasPaid> , Orchestrates<OrderAbandoned> , Orchestrates<CheckOrderHasBeenShipped> , Orchestrates<OrderShipped> , Orchestrates<CheckOrderHasDelayDuringShipment> , Orchestrates<OrderArrivedAtDestination> , Orchestrates<OrderCompleted> {...} but only Orchestrates<CancelOrder seems to be picked up. So I suppose (I did not find the line, but am under a strong impression this is so), that only the first Orchestrates is registered. Probably this is by design. From what I imagined a saga to be, it seems only logical that it receives many different messages, but I might be wrong. I might be wrong with my whole assumption, too :) How am I supposed to handle this? Are Sagas supposed to only handle one (in my case) a ChangeStateMessage<State or should I wire the other ConsumerOfs/Orchestrates by hand?

• GUI for generating XML

  - by Kenston

  Hello. Does anybody know of GUIs for generating XMLs? This means the user will not be presented with an IDE with support for XML for him to type XML codes. This would be helpful for non-technical people using the system. I know this sounds easy, given many libraries that can help in generating XMLs. The issue here is that the schema is really that flexible rather than being straightforward like representing books in a library with their properties. Imagine HTML, where we can create font tags inside a body, a table, a div, or nested even within itself. The solution is a WYSIWYG application that allows user to generate html codes (XML). However, that is good for XML applied in webpages since they involve visual aspect and design. My application of XML would focus on representing some conceptual and computational definitions, much like sql-like syntax, but more than that. I'm actually after the approach or previous works done or tried, although having a library/working framework for that would be better. Btw, I'm using Java for this project. Currently, I'm just thinking of presenting element tags where user will be able to drag and drop them and nest them with each other. And perhaps, assist them through a forms in inputing values for XML attributes. I'm still hoping if there are better ideas from the community. Thank you.

• How to configure database connection securely

  - by chiccodoro

  Similar but not the same: How to securely store database connection details Securely connecting to database within a application Hi all, I have a C# WinForms application connecting to a database server. The database connection string, including a generic user/pass, is placed in a NHibernate configuration file, which lies in the same directory as the exe file. Now I have this issue: The user that runs the application should not get to know the username/password of the general database user because I don't want him to rummage around in the database directly. Alternatively I could hardcode the connection string, which is bad because the administrator must be able to change it if the database is moved or if he wants to switch between dev/test/prod environments. So long I've found three possibilities: The first referenced question was generally answered by making the file only readable for the user that runs the application. But that's not not enough in my case (the user running the application is a person. The database user/pass are general and shouldn't even be accessible by the person.) The first answer additionally proposed to encrypt the connection data before writing it to the file. With this approach, the administrator is not able anymore to configure the connection string because he cannot encrypt it by hand. The second referenced question provides an approach for this very scenario but it seems very complicated. My questions to you: This is a very general issue, so isn't there any general "how-to-do-it" way, somehow a "design pattern"? Is there some support in .NET's config infrastructure? (optional, maybe out of scope) Can I combine that easily with the NHibernate configuration mechanism?

• Java method keyword "final" and its use

  - by Lukas Eder

  When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn't be allowed to set 1 as the default, for instance @Override public final int zblah() { return zblah(0); } // This method is not implemented here, but in a subclass @Override public abstract int zblah(int defaultZblah); } I do this for several reasons: It helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy) I think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it. So the final keyword works perfectly for me. My question is: Why is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?

• Best practices for managing updating a database with a complex set of changes

  - by Sarge

  I am writing an application where I have some publicly available information in a database which I want the users to be able to edit. The information is not textual like a wiki but is similar in concept because the edits bring the public information increasingly closer to the truth. The changes will affect multiple tables and the update needs to be automatically checked before affecting the public tables. I'm working on the design and I'm wondering if there are any best practices that might help with some particular issues. I want to provide undo capability. I want to show the user the combined result of all their changes. When the user says they're done, I need to check the underlying public data to make sure it hasn't been changed by somebody else. My current plan is to have the user work in a set of tables setup to be a private working area. Once they're ready they can kick off a process to check everything and update the public tables. Undo can be recorded using Command pattern saving to a table. Are there any techniques I might have missed or useful papers or patterns? Thanks in advance!

• How to lazy load scripts in YUI that accompany ajax html fragments

  - by Chris Beck

  I have a web app with Tabs for Messages and Contacts (think gmail). Each Tab has a Y.on('click') event listener that retrieves an HTML fragment via Y.io() and renders the fragment via node.setContent(). However, the Contact Tab also requires contact.js to enable an Edit button in the fragment. How do I defer the cost of loading contact.js until the user clicks on the Contacts tab? How should contact.js add it's listener to the Edit button? The Complete function of my Tab's on('click') event could serialize Get.script('contact.js') after Y.io('fragment'). However, for better performance, I would prefer to download the script in parallel to downloading the HTML fragment. In that case, I would need to defer adding an event listener to the Edit button until the Edit button is available. This seems like a common RIA design pattern. What is the best way to implement this with YUI? How should I get the script? How should I defer sections of the script until elements in the fragment are available in the DOM?

• I have two choices of Master's classes this fall. Which is the most useful?

  - by ahplummer

  (For background purposes and context): I am a Software Engineer, and manage other Software Engineers currently. I kind of wear two hats right now: one of a programmer, and one as a 'team lead'. In this regard, I've started going back to school to get my Master's degree with an emphasis in Computer Science. I already have a Bachelor's in Computer Science, and have been working in the field for about 13 years. Our primary development environment is a Windows environment, writing in .NET, Delphi, and SQL Server. Choice #1: CST 798 DATA VISUALIZATION Course Description: Basically, this is a course on the "Processing" language: http://processing.org/ Choice #2: CST 711 INFORMATICS Course Description: (From catalog): Informatics is the science of the use and processing of data, information, and knowledge. This course covers a variety of applied issues from information technology, information management at a variety of levels, ranging from simple data entry, to the creation, design and implementation of new information systems, to the development of models. Topics include basic information representation, processing, searching, and organization, evaluation and analysis of information, Internet-based information access tools, ethics and economics of information sharing.

• Absolutely positioned div on right causing scrollbar when the left doesn't

  - by Michael Snyder

  I'm trying to "flank" a centered div with some design elements that are absolutely positioned outside the main div's width. I'm getting a scroll bar due to the element on the right, but not the element on the left (IE6/7/8, Chrome, Firefox). How can I get rid of that horizontal scrollbar? <html> <head> <style type="text/css"> html, body { height: 100%; width: 100%; margin: 0; } body { text-align: center; } .wrapper { margin: 0 auto; position: relative; width: 960px; z-index: 0; } .main { background: #900; height: 700px; } .right, .left { position: absolute; height: 100px; width: 100px; } .right { background: #090; top: 0px; left: 960px; z-index: 1; } .left { background: #009; top: 0px; left: -100px; z-index: 1; } </style> </head> <body> <div class="wrapper"> <div class="main"></div> <div class="left"></div> <div class="right"></div> </div> </body> </html>

• Is there a good way to QuickCheck Happstack.State methods?

  - by Paul Kuliniewicz

  I have a set of Happstack.State MACID methods that I want to test using QuickCheck, but I'm having trouble figuring out the most elegant way to accomplish that. The problems I'm running into are: The only way to evaluate an Ev monad computation is in the IO monad via query or update. There's no way to create a purely in-memory MACID store; this is by design. Therefore, running things in the IO monad means there are temporary files to clean up after each test. There's no way to initialize a new MACID store except with the initialValue for the state; it can't be generated via Arbitrary unless I expose an access method that replaces the state wholesale. Working around all of the above means writing methods that only use features of MonadReader or MonadState (and running the test inside Reader or State instead of Ev. This means forgoing the use of getRandom or getEventClockTime and the like inside the method definitions. The only options I can see are: Run the methods in a throw-away on-disk MACID store, cleaning up after each test and settling for starting from initialValue each time. Write the methods to have most of the code run in a MonadReader or MonadState (which is more easily testable), and rely on a small amount of non-QuickCheck-able glue around it that calls getRandom or getEventClockTime as necessary. Is there a better solution that I'm overlooking?

• How is a relative JMP (x86) implemented in an Assembler?

  - by Pindatjuh

  While building my assembler for the x86 platform I encountered some problems with encoding the JMP instruction: enc inst size in bytes EB cb JMP rel8 2 E9 cw JMP rel16 4 (because of 0x66 16-bit prefix) E9 cd JMP rel32 5 ... (from my favourite x86 instruction website, http://siyobik.info/index.php?module=x86&id=147) All are relative jumps, where the size of each encoding (operation + operand) is in the third column. Now my original (and thus fault because of this) design reserved the maximum (5 bytes) space for each instruction. The operand is not yet known, because it's a jump to a yet unknown location. So I've implemented a "rewrite" mechanism, that rewrites the operands in the correct location in memory, if the location of the jump is known, and fills the rest with NOPs. This is a somewhat serious concern in tight-loops. Now my problem is with the following situation: b: XXX c: JMP a e: XXX ... XXX d: JMP b a: XXX (where XXX is any instruction, depending on the to-be assembled program) The problem is that I want the smallest possible encoding for a JMP instruction (and no NOP filling). I have to know the size of the instruction at c before I can calculate the relative distance between a and b for the operand at d. The same applies for the JMP at c: it needs to know the size of d before it can calculate the relative distance between e and a. How do existing assemblers implement this, or how would you implement this? This is what I am thinking which solves the problem: First encode all the instructions to opcodes between the JMP and it's target, and if this region contains a variable-sized opcode, use the maximum size, i.e. 5 for JMP. Then in some conditions, the JMP is oversized (because it may fit in a smaller encoding): so another pass will search for oversized JMPs, shrink them, and move all instructions ahead), and set absolute branching instructions (i.e. external CALLs) after this pass is completed. I wonder, perhaps this is an over-engineered solution, that's why I ask this question.

• 1 oracle schema support large reques per day , is this safe ?

  - by Hlex

  I 'm java system designer. As we have large project to do tightly, Those projects are java api without webpage. I design to create general flow engine to support all project. This idea use 1 oracle schema , having general transaction table . And others control routing table. They all nearly complete. But DBA Team concern that he is suffered to maintain very large request to 1 schema. 1 reason is if there are problem is some table. He must offline tablespace to fix. This is problem because all project will be affected. I try to convince by split data of each table to partition by project_code & "month number to delete" . Eaxmple partition: PROJ1_05 PROJ1_06 PROJ1_07 PROJ2_05 PROJ2_06 PROJ2_07 and all transaction table will store on its partition. So, If there are problem on any part of tablespace then he should offline some partition and another project with use same table should able to service Transaction per day should around 10Meg Record per day. Is this a good idea? If I must use 1 schema, what is strategy to do? Do you have any comment?

• How large a role does subjectiveness play in programming?

  - by Bob

  I often read about the importance of readability and maintainability. Or, I read very strong opinions about which syntax features are bad or good. Or discussions about the values of certain paradigms, like OOP. Aside from that, this same question floats about in my mind whenever I read debates on SO or Meta about subjective questions. Or read questions about best practices and sometimes find myself or others disagreeing. What role does subjectiveness play within the programming realm? Sometimes I think it plays a large role. Software developers are engineers in a way, but also people. A large part of programming is dealing with code that's human readable. This is very different from Math or Physics or other disciplines with very exact and structured rules. Here the exact structure and rules are largely up in the air, changeable on a whim, and hence the amount of languages in existence. And one person may find one language very readable, and another person may find their own language the most comforting. The same with practices. One person may not like certain accepted practices. I myself find splitting classes into different files very unreadable, for instance. But, I can't say rules haven't helped in general. Certain practices have and do make life easier. And new languages have given rise to syntax and structure that make life easier. There's certainly been a progression towards code that is easier to read and maintain even given a largely diverse group of people. So maybe these things aren't as subjective as I thought. It reminds me, in a way, of UI design. Certainly it's subjective, but then there's an entire discipline involved in crafting good UI and it tends to work. Is there something non-subjective about the ideas behind maintainability, readability, and other best practices? Is there something tangible to grasp when one develops a new language or thinks of new practices?

• Link click does nothing after ajax switching?

  - by Neil

  An odd case I'm trying to figure out here. I'm trying to design a mailbox system, and making some of the options ajax-y. Here's the scenario: We have a page with 2 tabs, inbox and compose. Inbox is a essentially a list of links of the form mailbox.php?msg=xxx. Clicking on the inbox or compose tabs does an ajax switch. So, let's say we're on an message page: mailbox.php?msg=123 I click on "compose" - it ajax switches to a compose form. I change my mind, click on "inbox" - it goes back to a list of messages. Note, the url has not changed at this point (all has been done through ajax). I click on the same message as before. It should go back into that message. However, nothing happens! The url it should go to (mailbox.php?msg=123) IS the url showing in the address bar, but, due to the earlier ajax activity, it's showing the inbox. Thoughts on how to resolve this? And, out of curiosity, an explanation? Normally, clicking on a link that takes you to a page you're already on will reload the page. Thanks!

• Python - Open default mail client using mailto, with multiple recipients

  - by victorhooi

  Hi, I'm attempting to write a Python function to send an email to a list of users, using the default installed mail client. I want to open the email client, and give the user the opportunity to edit the list of users or the email body. I did some searching, and according to here: http://www.sightspecific.com/~mosh/WWW_FAQ/multrec.html It's apparently against the RFC spec to put multiple comma-delimited recipients in a mailto link. However, that's the way everybody else seems to be doing it. What exactly is the modern stance on this? Anyhow, I found the following two sites: http://2ality.blogspot.com/2009/02/generate-emails-with-mailto-urls-and.html http://www.megasolutions.net/python/invoke-users-standard-mail-client-64348.aspx which seem to suggest solutions using urllib.parse (url.parse.quote for me), and webbrowser.open. I tried the sample code from the first link (2ality.blogspot.com), and that worked fine, and opened my default mail client. However, when I try to use the code in my own module, it seems to open up my default browser, for some weird reason. No funny text in the address bar, it just opens up the browser. The email_incorrect_phone_numbers() function is in the Employees class, which contains a dictionary (employee_dict) of Employee objects, which themselves have a number of employee attributes (sn, givenName, mail etc.). Full code is actually here (http://stackoverflow.com/questions/2963975/python-converting-csv-to-objects-code-design) from urllib.parse import quote import webbrowser .... def email_incorrect_phone_numbers(self): email_list = [] for employee in self.employee_dict.values(): if not PhoneNumberFormats.standard_format.search(employee.telephoneNumber): print(employee.telephoneNumber, employee.sn, employee.givenName, employee.mail) email_list.append(employee.mail) recipients = ', '.join(email_list) webbrowser.open("mailto:%s?subject=%s&body=%s" % (recipients, quote("testing"), quote('testing')) ) Any suggestions? Cheers, Victor

• dynamically created controls and responding to control events

  - by Dirk

  I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls. protected override void OnLoad(EventArgs e) { base.OnLoad(e); RenderDynamicControls() } private void RenderDynamicControls(){ //1. call service layer to retrieve form definition //2. create and add controls to page container } I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code: protected void MyButton_Click(object sender, EventArgs e) { RenderDynamicControlsALittleDifferently() } private void RenderDynamicControlsALittleDifferently() (){ //1. clear all controls from the page container added in RenderDynamicControls() //2. call service layer to retrieve form definition //3. create and add controls to page container } My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid. On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax. Any code/advice that make that transition easier would be much appreciated. Thanks

• Netbeans GUI building on pre-defined code

• Designing code for a duo Website + AIR desktop App

  - by faB

  I want to use AIR to create an OFFLINE version of a "webapp" kind of website (lots of ajax, front end code). Haven't been much further than the HelloWorld example, I keep wondering: how do you design your code, to maximize code reuse between the website (say in php or Java or .Net), and the AIR app ? Can you actually re-use 100% of the front end code, provided that it is designed to account for the AIR app ? How would you go about doing that ? For example, the website makes many Ajax calls which have latency, and uses listeners. The AIR app doesn't need listeners it could run database requests synchronously, and it doesn't need to run ajax calls right? Would you write an abstraction layer for that ? So that the same calls on the AIR app will not do a xmlhttp but instead implement the server-side code with AIR; and call the listener ? So you don't have to rewrite the front end code patterns ? Does this make sense ? It's really hard to search on Google. I'm thinking there must be a good article somewhere of somebody who went through and perhaps a framework to do that ?

• Appropriate wx.Sizer(s) for the job?

  - by MetaHyperBolic

  I have a space in which I would like certain elements (represented here by A, B, D, and G) to each be in its own "corner" of the design. The corners ought to line up as if each of the four elements was repelling the other; a rectangle. This is to be contained within an unresizable panel. I will have several similar panels and want to keep the location of the elements as identical as possible. (I needed something a little more complex than a wx.Wizard, but with the same general idea.) AAAAAAAAAA BB CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCC CCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCC CCCCCCCCCCCCCCCCCC DDD EEE FFF GGG A represents a text in a large font. B represents a numeric progress meter (e.g. "1 of 7") in a small font. C represents a large block of text. D, E, F, and G are buttons. The G button is separated from others for functionality. I have attempted nested wx.BoxSizers (horizontal boxes inside of one vertical box) without luck. My first problem with wx.BoxSizer is that the .SetMinSize on my last row has not been honored. The second problem is that I have no idea how to make the G button "take up space" without growing comically large, or how I can jam it up against the right edge and bottom edge. I have tried to use a wx.GridBagSizer, but ran into entirely different issues. After plowing through the various online tutorials and wxPython in Action, I'm a little frustrated. The relevant forums appear to see activity once every two weeks. "Playing around with it" has gotten me nowhere; I feel as if I am trying to smooth out a hump in ill-laid carpet.

• Viewing namespaced global variables in Visual Studio debugger?

  - by Chris

  When debugging a non-managed C++ project in Visual Studio 2008, I occasionally want to see the value of a global variable. We don't have a lot of these but those that are there all declared within a namespace called 'global'. e.g. namespace global { int foo; bool bar; ... } The problem is that when the code is stopped at a breakpoint, the default debugging tooltip (from pointing at the variable name) and quickwatch (shift-f9 on the variable name) don't take the namespace into consideration and hence won't work. So for example I can point at 'foo' and nothing comes up. If I shift-f9 on foo, it will bring up the quickwatch, which then says 'CXX0017: Error: symbol "foo" not found'. I can get around that by manually editing the variable name in the quickwatch window to prefix it with "global::" (which is cumbersome considering you have to do it each time you want to quickwatch), but there is no fix for the tooltip that I can work out. Setting the 'default namespace' of the project properties doesn't help. How can I tell the VS debugger to use the namespace that it already knows the variable is declared in (since it has the declaration right there), or, alternatively, tell it a default namespace to look for variables in if it doesn't find them? My google-fu has failed to find an answer. This report lists the same problem, with MS saying it's "by design", but even so I am hoping there is some way to work around it (perhaps with clever use of autoexp.dat?)

• Should I remove all inheritance from my model in order to work with ria services?

  - by TimothyP

  I've posted some questions on this before, but it's different. So consider a small portion of our model: Person Customer Employee Spouse Person is the base class which has 3 classes that inherit from it. These 4 are very central in our design and link to many other entities. I could solve all the problems I'm experiencing with ria-services by removing the inheritance but that would really increase the complexety of the model. The first problem I experienced was that I couldn't query for Customers, Employees or Spouses, but someone gave me a solution, which was to add something like this to the DomainService: public IQueryable<Employee> GetEmployees() { return this.ObjectContext.People.OfType<Employee>(); } public IQueryable<Customer> GetCustomers() { return this.ObjectContext.People.OfType<Customer>(); } public IQueryable<Spouse> GetSpouses() { return this.ObjectContext.People.OfType<Spouse>(); } Next I tried something that seemed very normal to me: var employee = new Employee() { //.... left out to reduce the length of this question }; var spouse = new Spouse() { //.... left out to reduce the length of this questions }; employee.Spouse = spouse; context.People.Add(spouse); context.People.Add(employee); context.SubmitChanges(); Then I get the following exception: Cannot retrieve an entity set for the derived entity type 'Spouse'. Use EntityContainer.GetEntitySet(Type) to get the entity set for the base entity type 'Person'. Even when the spouse is already in the database, and I retreive it first I get similar exceptions. Also note that for some reason in some places "Persons" is used instead of "People"... So how do I solve this problem, what am I doing wrong and will I keep running into walls when using ria services with inheritance? I found some references on the web, all saying it works and then some DomainService code in which they suposedly changed something but no details... I'm using VS2010 RC1 + Silveright 4

• .NET WebBrowser control with Adobe SVG Viewer

  I'm having problems with SVG files loading in a .NET 2.0 WebBrowser control. If I create a new WinForms application project, drag a WebBrowser control and a button onto the Form1.cs design surface, and add a line to the button's on-click handler to set the Url property of the WebBrowser control to an SVG file, I get two IE script errors at runtime (as in, the dialog you get when there is a Javascript problem). The only line of code I'm writing is therefore: webBrowser1.Url = new Uri(@"http://wiki.allegro.cc/pub/f/fb/Grozilla.svg"); This SVG file loads fine if I browse directly to the link with IE; the errors I get via my test app are: line 2, char 1, error: Invalid character, followed by line 1, char 1, error: Object expected (assuming I answer yes to the prompt to 'continue running scripts on this page'). I'm using IE 7.0.5730.13, Adobe SVG Viewer 3.03 build 94, Visual Studio 2008. Can anyone replicate this? Has anyone seen it/got any idea how to fix it? (edit: previously setting the URL in the constructor for the purposes of the example, but this raised the question of whether or not the control had finished initialising, so have changed the example to use a button - the problem still occurs. This bug originally appeared in production code so the example program I wrote was an attempt to isolate the issue and reproduce it as simply as possible.) (edit 2: having tested on several different machines, this problems seems to be related to IE7 - run IE6, and everything works fine.)

• Pass checkbox values with Jquery to PHP and display result in div

  I want to filter realtime results with jQuery (just like on this site http://shop.www.hi.nl/hi/mcsmambo.p?M5NextUrl=RSRCH). So when someones checks a checkbox the results should update realtime (in a div). Now I'm a newbie with jQuery and I've tried lots of examples but I can't get it to work. Here's my code, could anyone tell what I'm doing wrong? Thank you very much! HTML <div id="c_b"> Kleur:<br /> <input type="checkbox" name="kleur[1]" value="Blauw"> Blauw <br /> <input type="checkbox" name="kleur[2]" value="Wit"> Wit <br /> <input type="checkbox" name="kleur[3]" value="Zwart"> Zwart <br /> <br /> Operating System:<br /> <input type="checkbox" name="os[1]" value="Android"> Android <br /> <input type="checkbox" name="os[2]" value="Apple iOS"> Apple iOS <br /> </div> <div id="myResponse">Here should be the result</div> jQuery function updateTextArea() { var allVals = []; $('#c_b :checked').each(function() { allVals.push($(this).val()); }); var dataString = $(allVals).serialize(); $.ajax({ type:'POST', url:'/wp-content/themes/u-design/filteropties.php', data: dataString, success: function(data){ $('#myResponse').html(data); } }); } $(document).ready(function() { $('#c_b input').click(updateTextArea); updateTextArea(); }); PHP //Just to see if the var passing works echo var_export($_POST);

• Visual Studio 2010 / ASP.NET MVC / Publish

  - by SevenCentral

  I just did a clean install on Windows 7 x64 Professional with the final release of Visual Studio 2010 Premium. In order to duplicate what I'm experiencing do the following in: Create a new ASP.NET MVC 2 Web Application Right click the project and select Properties On the Web tab, select "Use Local IIS Web Server" Click on Create Virtual Directory Save all Unload the project Edit the project file Change MvcBuildViews to true Save all Reload project Right click the project and select Publish Choose the file system publish method Enter a target location Choose Delete all existing files Select Publish Right click the project Select Publish Each time I do the above I get the following errror: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level..." The error originates from obj\debug\package\packagetmp\web.config, relative to the project directory. I can repeat this all day long with any MVC 2 project I've built. In order to fix this problem, I need to set MvcBuildViews to false in the project file. That's not really an option. This wasn't a problem in Visual Studio 2008 and it seems to be an issue with the way the Publish command stages files beneath the project directory. Can anyone else duplicate this error? Is this a bug or by design? Is there a fix, workaround, etc...? Thanks.

• Question on boost array initializer

  - by ArunSaha

  I am trying to understand the boost array. The code can be read easily from author's site. In the design rationale, author (Nicolai M. Josuttis) mentioned that the following two types of initialization is possible. boost::array<int,4> a = { { 1, 2, 3 } }; // Line 1 boost::array<int,4> a = { 1, 2, 3 }; // Line 2 In my experiment with g++ (version 4.1.2) Line 1 is working but Line 2 is not. (Line 2 yields the following: warning: missing braces around initializer for 'int [4]' warning: missing initializer for member 'boost::array<int, 4ul>::elems' ) Nevertheless, my main question is, how Line 1 is working? I tried to write a class similar to array.hpp and use statement like Line 1, but that did not work :-(. Can somebody explain me? Is there some boost specific thing happening in Line 1 that I need to be aware of? Thanks in advance. Regards,

• Presenting an image cropping interface

  - by wkw

  I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.
