  • Object mapping in objective-c (iphone) from JSON

    - by freshfunk
    For my iPhone app, I'm consuming a RESTful service and getting JSON. I've found libraries to deserialize this into an NSDictionary. However, I'm wondering if there are any libraries to deserialize the JSON/NSDictionary/Property List into my object (an arbitrary one on my side). The java equivalent would be the object-relational mappers although the sort of object mapping I'm looking for is relatively straightforward (simple data types, no complex relationships, etc.). I noticed that Objective-C does have introspection so it seems theoretically possible but I haven't found a library to do it. Or is there a simple way to load an object from an NSDictionary/Property List object that doesn't require modification every time the object changes? For example: { "id" : "user1", "name" : "mister foobar" "age" : 20 } gets loaded into object @interface User : NSObject { NSString *id; NSString *name; int *age; }

  • How to avoid visual artifacts when hosting WPF user controls within a WinForms MDI app?

    - by jpierson
    When hosting WPF user controls within a WinForms MDI app there is a drawing issue when you have multiple forms that overlap each other that causes very distinct visual artifacts. These artifacts are mostly visible after dragging one child form over another one that also hosts WPF content or by allowing the edges of the child form to be clipped by the main MDI parent when dragging it around. After the drag and drop of the child form is completed the artifacts stay around gernally but I've found that setting focus to a different application's window and then refocusing back on to my application window that it is redrawn and all is good again until the child forms are moved once again. Please see the image below which demonstrates the problem. Since many at Microsoft insist that the WinForms MDI is already a complete solution for MDI even when dealing with WPF I find it hard to believe any of them have ever actually tried creating a mostly WPF app that utilizes WinForms MDI otherwise it would be hard to recommend while keeping a straignt face. I'm hoping to either come up with proof that this solution truly is not acceptable or possibly find a way to overcome this and a few other specific issues.

  • Crazy idea: Connect .NET and SAP with SAP JCo using IKVM.NET

    - by Kottan
    Because the SAP Connector for .NET is no longer maintained by SAP, I am now looking for an alternative to connect the Microsoft world with the SAP world. I know there a third party products like ERPConnect, but I want to do this with tools from SAP. Therefore there arised the crazy idea to use the SAP Java Connector in combination with the tool IKVM.NET (www.ikvm.net/devguide/net2java.html). IKVM.NET provides The IKVMC tool, which converts Java bytecode to .NET dll's and exe's. "No sooner said than done!" I converted the SAP JCo to .NET dlls and created a new Visual Studio solution. I put all the JCO files into a subdirectory of my solution. I set 2 references to the generated IKVM.OpenJDK.Core.dll and sapjco.dll. Great, all JCO classes where now available as .NET classes. Full of optimism I wrote some little code to connect to a SAP system. JCO.Client client = null; client = JCO.createClient(...) The compiliation of my testcode had no errors. "Wonderful !" I thought. Then I started my tetstapplication. Unfortunately I got an exception calling JCO.createClient: Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'\r\nno sapjcorfc in java.library.path I have 2 questions on this topic. 1) Do you think my idea using SAP Java Connector to connect .NET with SAP is a good idea or is it nonsens ? Perhaps someone had already the same idea ;-) 2) How can the above exception be solved ?

  • How to download media content on demand and reuse from browser cache in silverlight

    - by Andrew
    Hi. I have a problem with simple silverlight app, this app has a couple of buttons, each button sets mediaelement source to a short mp3 file and plays it, my problem is that when i press the same button second time it re-downloads mp3 file again but i think it shouldn't, instead it should use a copy of browser cached mp3 file that was downloaded when a button was pressed for the first time. I'm using sl4 and links in mediaelement are just simple uri's, i need to make it working in this way that when some mp3 was downloaded it will be cached on the client browser and further click on button will use a cached version of file instead of downloading it again and wasting my bandwidth. Any ideas ?

  • When to use an IOC container?

    - by nivlam
    I'm trying to understand when I should use a container versus manually injecting dependencies. If I have an application that uses a 1-2 interfaces and only has 1-2 concrete implementations for each interface, I would lean towards just handling that myself. If I have a small application that uses 2-3 interfaces and each interface has 2-3 concrete implementations, should I use a full-blown container? Would something something simple like this suffice? Basically I'm trying to understand when it's appropriate to manually handle these dependencies, when (or if) I should use something simple like the above, and when to use an IOC container like Ninject, Windsor, etc....

  • WCF push to client through firewall?

    - by Sire
    See also How does a WCF server inform a WCF client about changes? (Better solution then simple polling, e.g. Coment or long polling) I need to use push-technology with WCF through client firewalls. This must be a common problem, and I know for a fact it works in theory (see links below), but I have failed to get it working, and I haven't been able to find a code sample that demonstrates it. Requirements: WCF Clients connects to server through tcp port 80 (netTcpBinding). Server pushes back information at irregular intervals (1 min to several hours). Users should not have to configure their firewalls, server pushes must pass through firewalls that have all inbound ports closed. TCP duplex on the same connection is needed for this, a dual binding does not work since a port has to be opened on the client firewall. Clients sends heartbeats to server at regular intervals (perhaps every 15 mins) so server knows client is still alive. Server is IIS7 with WAS. The solution seems to be duplex netTcpBinding. Based on this information: WCF through firewalls and NATs Keeping connections open in IIS But I have yet to find a code sample that works.. I've tried combining the "Duplex" and "TcpActivation" samples from Microsoft's WCF Samples without any luck. Please can someone point me to example code that works, or build a small sample app. Thanks a lot!

  • Binary serialization/de-serialization in C++ and C#

    - by 6pack kid
    Hello. I am working on a distributed application which has two components. One is written in standard C++ (not managed C++) and the other one is written in C#. Both are communicating via a message bus. I have a situation in which I need to pass objects from C++ to C# application and for this I need to serialize those objects in C++ and de-serialize them in C# (something like marshaling/un-marshaling in .NET). I need to perform this serialization in binary and not in XML (due to performance reasons). I have used Boost.Serialization to do this when both ends were implemented in C++ but now that I have a .NET application on one end, Boost.Serialization is not a viable solution. I am looking for a solution that allows me to perform (de)serialization across C++ and .NET boundary i.e., cross platform binary serialization. I know I can implement the (de)serialization code in a C++ dll and use P/Invoke in the .NET application, but I want to keep that as a last resort. Also, I want to know if I use some standard like gzip, will that be efficient? Are there any other alternatives to gzip? What are the pros/cons of them? Thanks

  • Visual Studio Templates - adding additional pre-existing projects

    - by Bob Palmer
    Hey all, I'm working on a Visual Studio template where the generated project relies on a number of references, which happen to be other projects under source control. The question is how do I set this up in my ProjectGroup template? For example, if I have an already existing project at "C:\Stuff\MyUtilityProject\Utility.csproj" with a single file (Tools.cs) that I want to add to my template, how would I go about this? Here's what my vstempalte looks like. FYI - I am having no issues with the ProjectTemplateLink or creation of the Solution folder, just in adding the pre-existing Utility.csproj to my new solution: Thanks in advance! <VSTemplate Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="ProjectGroup"> <TemplateData> <Name>MySampleSolution</Name> <Description>My Test Project</Description> <ProjectType>CSharp</ProjectType> <Icon>__TemplateIcon.ico</Icon> </TemplateData> <TemplateContent> <ProjectCollection> <SolutionFolder Name="Content"> <Project File="C:\Stuff\MyUtilityProject\Utility.csproj"> <ProjectItem>Tools.cs</ProjectItem> </Project> </SolutionFolder> <ProjectTemplateLink ProjectName="MyWorkingTemplate"> MyWorkingTemplate\MyTemplate.vstemplate </ProjectTemplateLink> </ProjectCollection> </TemplateContent> </VSTemplate>

  • How would you solve this graph theory handshake problem in python?

    - by Zachary Burt
    I graduated college last year with a degree in Psychology, but I also took a lot of math for fun. I recently got the book "Introductory Graph Theory" by Gary Chartrand to brush up on my math and have some fun. Here is an exercise from the book that I'm finding particularly befuddling: Suppose you and your husband attended a party with three other married couples. Several handshakes took place. No one shook hands with himself (or herself) or with his (or her) spouse, and no one shook hands with the same person more than once. After all the handshaking was completed, suppose you asked each person, including your husband, how many hands he or she had shaken. Each person gave a different answer. a) How many hands did you shake? b) How many hands did your husband shake? Now, I've been reasoning about this for a while, and trying to draw sample graphs that could illustrate a solution, but I'm coming up empty-handed. My logic is this: there are 8 different vertices in the graph, and 7 of them have different degrees. The values for the degrees must therefore be 0, 1, 2, 3, 4, 5, 6, and x. The # of degrees for one married couple is (0, 6). Since all graphs have an even number of odd vertices, x must be either 5, 3, or 1. What's your solution to this problem? And, if you could solve it in python, how would you do it? (python is fun.) Cheers.

  • jQuery — Nested Sortables Plugin — Disabling sortability between parents

    - by AJB
    I've got a question that I think is simple but I've not been able to figure it out. This is in regard to this plugin: http://mjsarfatti.com/sandbox/nestedSortable/ Essentially, I want to disable the ability to sort children outside of their parents. So, I've got this: CATEGORY 1 ITEM 1.1 ITEM 1.2 ITEM 1.3 CATEGORY 2 ITEM 2.1 ITEM 2.2 ITEM 2.3 So, I'd like to provide the ability for users to sort the children within their category, and the ability to sort the categories themselves. But I want to disable the ability to move a child to another parent. (e.g. ITEM 1.1 cannot be moved to CATEGORY 2). And also I would like to disable the abilty to nest any parents in any children. I tried setting it so that the 'nestedSortable' function is called for every new OL but that simple disables sorting for everything entirely. Thanks for any help.

  • Need to open links in new tab in ie8 !

    - by BHOdevelopper
    I have a sidebar (right sided iframe) and when i click on a link in it, it opens a new window in IE8, (in firefox it open a new tab). What do i need to do to open links in IE8 in a new tab. I already set the Tools-Internet Options-Settings- 'Always open pop-ups in a new tab' and 'A new tab in the current window' open in new tab but still doesn't work. My links are pretty simple, what am i missing ? exemple: text. Also some site are saying to register Regsvr32 actxprxy.dll to fix this problem, still doesn't work. And i want this to work with a simple click, no 'right-click-open in new tab' option. I also hope i won't get the 'can't change how ie8 works' answer. ;)

  • WSDL Object model

    - by Swaroop
    I'm using the WSDL object model (WOM) along with XSOM for a project of mine. The WOM gives me a way to drill down and look at messages and the message types which are element declarations. However, I am unable to find a way to parse the simple and complex types. The APIs are tricky. There seems to be some kind of a connection between WOM and XSOM. I'd really appreciate it if you could tell me how I can parse the simple and the complex types in my .wsdl file.

  • OCR: How to improve accuracy - existing libraries for removing non-text 'furniture', shapes, etc to

    - by Rob
    I want to remove rectangles etc that enclose text in a screenshot image, so that I can perform optical character recognition to get accurate text from the screenshot. Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.

  • cookieless sessions with ajax

    - by thezver
    ok, i know you get sick from this subject. me too :( I've been developing a quite "big application" with PHP & kohana framework past 2 years, somewhat-successfully using my framework's authentication mechanism. but within this time, and as the app grown, many concerning state-preservation issues arisen. main problems are that cookie-driven sessions: can't be used for web-service access ( at least it's really not nice to do so.. ) in many cases problematic with mobile access don't allow multiple simultaneous apps on same browser ( can be resolved by hard trickery, but still.. ) requires many configurations and mess to work 100% right, and that's without the --browser issues ( disabled cookies, old browsers bugs & vulnerabilities etc ) many other session flaws stated in this old thread : http://lists.nyphp.org/pipermail/talk/2006-December/020358.html After a really long research, and without any good library/on-hand-solution to feet my needs, i came up with a custom solution to majority of those problems . Basically, i'ts about emulating sessions with ajax calls, with additional security/performance measures: state preserved by interchanging SID(+hash) with client on ajax calls. state data saved in memcache(or equivalent), indexed by SID security achieved by: appending unpredictible hash to SID egenerating hash on each request & validating it validating fingerprint of client on each request ( referrer,os,browser etc) (*)condition: ajax calls are not simultaneous, to prevent race-condition with session token. (hopefully Ext-Direct solves that for me) From the first glance that supposed to be not-less-secure than equivalent cookie-driven implementation, and at the same time it's simple, maintainable, and resolves all the cookies flaws.. But i'm really concerned because i often hear the rule "don't try to implement custom security solutions". I will really appreciate any serious feedback about my method, and any alternatives. also, any tip about how to preserve state on page-refresh without cookies would be great :) but thats small technical prob. Sorry if i overlooked some similar post.. there are billions of them about sessions . Big thanks in advance ( and for reading until here ! ).

  • How to update a QPixmap in a QGraphicsView with PyQt

  • Rhino Mocks, Dependency Injection, and Separation of Concerns

    - by whatispunk
    I am new to mocking and dependency injection and need some guidance. My application is using a typical N-Tier architecture where the BLL references the DAL, and the UI references the BLL but not the DAL. Pretty straight forward. Lets say, for example, I have the following classes: class MyDataAccess : IMyDataAccess {} class MyBusinessLogic {} Each exists in a separate assembly. I want to mock MyDataAccess in the tests for MyBusinessLogic. So I added a constructor to the MyBusinessLogic class to take an IMyDataAccess parameter for the dependency injection. But now when I try to create an instance of MyBusinessLogic on the UI layer it requires a reference to the DAL. I thought I could define a default constructor on MyBusinessLogic to set a default IMyDataAccess implementation, but not only does this seem like a codesmell it didn't actually solve the problem. I'd still have a public constructor with IMyDataAccess in the signature. So the UI layer still requires a reference to the DAL in order to compile. One possible solution I am toying with is to create an internal constructor for MyBusinessLogic with the IMyDataAccess parameter. Then I can use an Accessor from the test project to call the constructor. But there's still that smell. What is the common solution here. I must just be doing something wrong. How could I improve the architecture?

  • Problem with boost::find_format_all, boost::regex_finder and custom regex formatter (bug boost 1.42)

    - by Nikko
    I have a code that has been working for almost 4 years (since boost 1.33) and today I went from boost 1.36 to boost 1.42 and now I have a problem. I'm calling a custom formatter on a string to format parts of the string that match a REGEX. For instance, a string like: "abc;def:" will be changed to "abc\2Cdef\3B" if the REGEX contains "([;:])" boost::find_format_all( mystring, boost::regex_finder( REGEX ), custom_formatter() ); The custom formatter looks like this: struct custom_formatter() { template< typename T > std::string operator()( const T & s ) const { std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } } This worked fine but with boost 1.42 I know have "non initialized" s.match_results() which yield to boost::exception_detail::clone_implINS0_::error_info_injectorISt11logic_errorEEEE - Attempt to access an uninitialzed boost::match_results< class. This means that sometimes I am in the functor to format a string but there is no match. Am I doing something wrong? Or is it normal to enter the functor when there is no match and I should check against something? for now my solution is to try{}catch(){} the exception and everything works fine, but somehow that doesn't feel very good. EDIT1 Actually I have a new empty match at the end of each string to parse. EDIT2 : one solution inspired by ablaeul template< typename T > std::string operator()( const T & s ) const { if( s.begin() == s.end() ) return std::string(); std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } *EDIT3 Seems to be a bug in (at least) boost 1.42 *

  • Filter Dynamically Calendar View SharePoint

    - by lerac
    Hello world I'm using SP wss 3.0 wondering if anybody knows how to filter a calendar view in SharePoint dynamically based upon the current user. It's not the simple question of using [ME] because this will not work with single line text fields. Also users do not add the items, they are being imported. So filtering on the basis of Created by, Modified by, Assigned to, or People picking data is not a option. Already managed to get to the current user in a jScript variable, now I would like to filter it in the calendar view. Been searching for a long time now, but can't seem to find anything. Altough filtering with a all items view is possible, yet I can't seem to find a way to dynamically filter a calendar view. Already tried modifing allitems.aspx view page in Designer Fooling around with CAML jScript (as far as I know) Calculated views Google (find more other cool things then a solution) Ofcourse I don't expect a solution on a silver platter (ofcourse would be nice ;) ), but if somebody can point me into a direction I already would be quite happy.

  • How can I internationalize strings representing C# enum values?

    - by Duke
    I've seen many questions and answers about mapping strings to enums and vice-versa, but how can I map a series of localized strings to enums? Should I just create an extension method like this that returns the proper string from a resource file? Is there a way to localize attributes (like "Description") that are used in solutions like this? Which is the preferred solution - extension method or attributes. It seems to me that this isn't the intended purpose of attributes. In fact, now that I think about it, if I were to use an extension method an attribute seems like something I'd use to specify a key in a resource file for the localized string I want to use in place of the enum value. EDIT - example: Given the following enum, public enum TransactionTypes { Cheque = 1, BankTransfer = 2, CreditCard = 3 } I would like a way to map each type to a localized string. I started off with an extension method for the enum that uses a switch statement and strongly typed references to the resource file. However, an extension method for every enum doesn't seem like a great solution. I've started following this to create a custom attribute for each enumerated value. The attribute has a base name and key for the resource file containing localized strings. In the above enum, for example, I have this: ... [EnumResourceAttribute("FinancialTransaction", "Cheque")] Cheque = 1, ... Where "FinanacialTransaction" is the resx file and "Cheque" is the string key. I'm trying to create a utility method to which I could pass any value from any enumeration and have it return the localized string representation of that value, assuming the custom attribute is specified. I just can't figure out how to dynamically access a resource file and a key within it.

  • Exchanging strings (PChar) between a Freepascal compiled DLL and a Delphi compiled EXE

    - by John Riche
    After a lot of experimentations, I found a way to exchange PChar from a FreePascal compiled DLL with a Delphi compiled EXE. I'm in charge of both the DLL and EXE source code but one MUST BE in FreePascal and the other one in Delphi. My solution involves the following methods in the DLL: function GetAString(): PChar; var aString: string; begin aString := 'My String'; result := StrAlloc(length(aString) + 1); StrPCopy(result, aString); end; procedure FreeString(aString: PChar); begin StrDispose(aString); end; And from the Delphi EXE, to call the GetAString method, I need to Call the GetAString method, save the PChar to an actual Delphi String and call the FreeString method. Is this the best way of exchanging a string from a FreePascal DLL with a Delphi EXE ? Can I avoid the call to FreeString from Delphi ? And finally, if that's the correct solution, how will it behave with Delphi 2010 and the WideString by default: do I need to force WidePChar in FreePascal too ?

But in IE, I get this: VerifyError: Error #1033: Cpool entry 36 is wrong type. ReferenceError: Error #1065: Variable FBJS is not defined. What happen? what does it mean? :)
