  • Custom prerequsites to visual studio setup project

    - by Sandy
    I have a Visual Studio Setup project and have followed the steps mentioned in this link to load the Shared Add-in Support Update for the Microsoft .NET Framework 2.0 (KB908002) to the prerequisites list. The entry appears but there is this following warning shown No 'HomeSite' attribute has been provided for 'Shared Add-in Support Update for Microsoft .NET Framework 2.0 (KB908002)', so the package will be published to the same location as the bootstrapper. I use the Download component from the component vendor's website option. How do I set a homesite for this update so that the update is directly downloaded and installed. I do not want to distribute the update along with my setup. Thanks

  • Using Singleton synchronized array with NSThread

    - by hmthur
    I have a books app with a UISearchBar, where the user types any book name and gets search results (from ext API call) below as he types. I am using a singleton variable in my app called retrievedArray which stores all the books. @interface Shared : NSObject { NSMutableArray *books; } @property (nonatomic, retain) NSMutableArray *books; + (id)sharedManager; @end This is accessed in multiple .m files using NSMutableArray *retrievedArray; ...in the header file retrievedArray = [[Shared sharedManager] books]; My question is how do I ensure that the values inside retrievedArray remain synchronized across all the classes. Actually the values inside retrievedArray gets added through an NSXMLParser (i.e. through external web service API). There is a separate XMLParser.m file, where I do all the parsing and fill the array. The parsing is done on a separate thread. - (void) run: (id) param { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL: [self URL]]; [parser setDelegate: self]; [parser parse]; [parser release]; NSString *tmpURLStr = [[self URL]absoluteString]; NSRange range_srch_book = [tmpURLStr rangeOfString:@"v1/books"]; if (range_srch_book.location != NSNotFound) [delegate performSelectorOnMainThread:@selector(parseDidComplete_srch_book) withObject:nil waitUntilDone:YES]; [pool release]; } - (void) parseXMLFile: (NSURL *) url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; [self setURL: url]; NSThread* myThread = [[NSThread alloc] initWithTarget:self selector:@selector(run:) object: nil]; [retrievedArray removeAllObjects]; [myThread start]; [pool release]; } There seems to be some synchronization issues if the user types very quickly (It seems to be working fine if the user types slowly)....So there are 2 views in which the content of an object in this shared array item is displayed; List and Detail. If user types fast and clicks on A in List view, he is shown B in detail view...That is the main issue. I have tried literally all the solutions I could think of, but am still unable to fix the issue. Please suggest some suitable fixes.

  • How to create an application which embeds and runs Python code without local Python installation?

    - by Robert
    Hello fellow software developers. I want to distribute a program which is scriptable by embedding the Python interpreter. What I don't want is that the user has to install Python first. So I'm looking for a solution where I distribute only the following components: my program executable and its libraries the Python library (dll/so) a ZIP-file containing all necessary Python modules and libraries. How can I accomplish this? Do you have a step-by-step recipe for me? The solution should be suitable for both Windows and Linux. Thanks in advance.

  • Java compilers or JVM languages that support goto?

    - by unknown
    Is there a java compiler flag that allows me to use goto as a valid construct? If not, are there any third-party java compilers that supports goto? If not, are there any other languages that support goto while at the same time can easily call methods written in Java? The reason is I'm making a language that is implemented in Java. Gotos are an important part of my language; I want to be able to compile it to native or JVM bytecode, although it has to be able to easily use Java libraries (ie. C supports goto, but to use it I'd have to rewrite the libraries in C). I want to generate C or Java, etc source files, and not bytecode or machine code. I'm using a third-party compiler to do that.

  • Performing complicated XPath queries in Scala

    - by Ken Bloom
    What's the simplest API to use in scala to perform the following XPath queries on a document? //s:Annotation[@type='attitude']/s:Content/s:Parameter[@role='type' and not(text())] //s:Annotation[s:Content/s:Parameter[@role='id' and not(text())]]/@type The only documentation I can find on Scala's XML libraries has no information on performing complicated real XPath queries. I used to like JDOM for this purpose (in Java), but since JDOM doesn't support generics, it will be painful to work with in Scala. (Other XML libraries for Java have tended to be even more painful in Java, but I admit I don't know the landscape real well.)

  • jaxb unmarshal problem

    - by Hoax
    private JAXBContext jaxbContext; private Marshaller marshaller; private Unmarshaller unmarshaller; private PoiList db; public XMLHandler() { try { JAXBContext.newInstance("x.y.shared"); } catch (JAXBException e) { e.printStackTrace(); } } public PoiList readXML() { try { unmarshaller = jaxbContext.createUnmarshaller(); unmarshaller.setEventHandler(new XMLValidEventHandler()); db = (PoiList) unmarshaller.unmarshal(new File("src/source.xml")); } catch (JAXBException e) { e.printStackTrace(); } return db; } gets me this Exception in thread "main" java.lang.NullPointerException at com.sem.server.XMLHandler.readXML(XMLHandler.java:32) at sem.server.testDataAPI.main(testDataAPI.java:13) Line 32 in this case is the jaxbContext.createUnmarshaller() Line. packages are x.y.client x.y.server (includes the XMLHandler) x.y.shared (includes jaxb generated classes) not really sure what the problem is. any help is appreciated!

  • GIS: line_locate_point() in Python

    - by miracle2k
    I'm pretty much a beginner when it comes to GIS, but I think I understand the basics - it doesn't seem to hard. But: All these acronyms and different libraries, GEOS, GDAL, PROJ, PCL, Shaply, OpenGEO, OGR, OGC, OWS and what not, each seemingly depending on any number of others, is slightly overwhelming me. Here's what I would like to do: Given a number of points and a linestring, I want to determine the location on the line closest to a certain point. In other words, what PostGIS's line_locate_point() does: http://postgis.refractions.net/documentation/manual-1.3/ch06.html#line%5Flocate%5Fpoint Except I want do use plain Python. Which library or libraries should I have a look at generally for doing these kinds of spatial calculations in Python, and is there one that specifically supports a line_locate_point() equivalent?

  • How do I set permissions on a Server 2003 folder

    - by Richard210363
    Hi There, In my part time position as entire IT department at my Office ( I'm a MCSD developer normally ) I have been asked to change a shared folder. Only I don't really understand all the Shared / Security options. I have a folder that must be accessed by 2 people in the company (and no one else). They both must have read/write/edit and change access. They must be able to read/write/edit each others files; existing or newly created. Should be easy but I'm a bit overwhelemd by all the choices. What should I set? Thanks for your help richard

  • Linux friendly (.NET/Mono) browser object?

    - by HankB
    Hi folks, A friend of mine (familiar with C# and .NET on Windows) has asked how to port some functionality to a Linux host. This functionality is based on a JSP web page that fetches some data from the host server and displays it in a banner on a page. His Win/C#/.NET code simply creates a browser object which loads the page and he then inspects the resulting object to extract the data. I'm wondering what alternatives exist to duplicate this function on Ubuntu Linux. I'm not certain that the necessary libraries exist on this installation. I can assume that things like Perl and Python are ubiquitous, but I am not familiar with any libraries that include a browser object capable of executing javascript and exposing the results to another program. Any suggestions that lead in this direction are welcome. Thanks!

  • CUDA small kernel 2d convolution - how to do it

    - by paulAl
    I've been experimenting with CUDA kernels for days to perform a fast 2D convolution between a 500x500 image (but I could also vary the dimensions) and a very small 2D kernel (a laplacian 2d kernel, so it's a 3x3 kernel.. too small to take a huge advantage with all the cuda threads). I created a CPU classic implementation (two for loops, as easy as you would think) and then I started creating CUDA kernels. After a few disappointing attempts to perform a faster convolution I ended up with this code: http://www.evl.uic.edu/sjames/cs525/final.html (see the Shared Memory section), it basically lets a 16x16 threads block load all the convolution data he needs in the shared memory and then performs the convolution. Nothing, the CPU is still a lot faster. I didn't try the FFT approach because the CUDA SDK states that it is efficient with large kernel sizes. Whether or not you read everything I wrote, my question is: how can I perform a fast 2D convolution between a relatively large image and a very small kernel (3x3) with CUDA?

  • Visual Studio 2008 resolving wrong reference

    - by e28Makaveli
    In my project file, I have the following entry: <Reference Include="Microsoft.Practices.Unity, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> <HintPath>..\..\..\..\Libraries\Microsoft.Practices.Unity.dll</HintPath> </Reference> which in absolute terms translates to: C:\dev\LUT600 2.1.1\OCC600\Libraries Somehow, when I try to compile the project, Visual Studio loads a reference from a totally different path: /reference:"C:\Program Files\Microsoft Enterprise Library 4.1 - October 2008\Bin\Microsoft.Practices.Unity.dll. How it resolves to this location is a complete mystery as this DLL is not referenced anywhere in this project. I have set Specific Verion to true but it still resolves the reference from this location. Any ideas? TIA. Klaus

  • Atoms and references

    - by StackedCrooked
    According to the book Programming Clojure refs manage coordinated, synchronous changes to shared state and atoms manage uncoordinated, synchronous changes to shared state. If I understood correctly "coordinated" implies multiple changes are encapsulated as one atomic operation. If that is the case then it seems to me that coordination only requires using a dosync call. For example what is the difference between: (def i (atom 0)) (def j (atom 0)) (dosync (swap! i inc) (swap! j dec)) and: (def i (ref 0)) (def j (ref 0)) (dosync (alter i inc) (alter j dec))

  • VB.Net List.Find. Pass values to predicate

    - by Beta033
    Having a bit of trouble using the List.Find with a custom predicate i have a function that does this private function test () Dim test As Integer = keys.Find(AddressOf FindByOldKeyAndName).NewKey here's the function for the predicate Private Shared Function FindByOldKeyAndName(ByVal k As KeyObj) As Boolean If k.OldKey = currentKey.OldKey And k.KeyName = currentKey.KeyName Then Return True Else Return False End If End Function by doing it this way means i have to have a shared "currentKey" object in the class, and i know there has to be a way to pass in the values i'm interested in of CurrentKey (namely, keyname, and oldkey) ideally i'd like to call it by something like keys.Find(AddressOf FindByOldKeyAndName(Name,OldVal)) however when i do this i get compiler errors. How do i call this method and pass in the values?

  • Store return value of function in reference C++

    - by Ruud v A
    Is it valid to store the return value of an object in a reference? class A { ... }; A myFunction() { A myObject; return A; } //myObject goes out of scope here void mySecondFunction() { A& mySecondObject = myFunction(); } Is it possible to do this in order to avoid copying myObject to mySecondObject? myObject is not needed anymore and should be exactly the same as mySecondObject so it would in theory be faster just to pass ownership of the object from one object to another. (This is also possible using boost shared pointer but that has the overhead of the shared pointer.) Thanks in advance.

  • How to use autoconf with C++0x features

    - by themis
    What are the best practices for using autoconf in conjunction with shared_ptr and other TR1/BOOST C++0x templates so as to maximize portability and maintainability? With autoconf I can determine whether shared_ptr is available as std::tr1::shared_ptr and/or boost::shared_ptr. Given that the same feature has two different names, I have the following questions: In the code, how should shared_ptr be referenced? Should std::tr1::shared_ptr be preferred over boost::shared_ptr? For the first, the code is currently using preprocessor conditionals allowing non-qualified references to shared_ptr, a la #if HAVE_STD_TR1_SHARED_PTR using std::tr1::shared_ptr; #elif HAVE_BOOST_SHARED_PTR using boost::shared_ptr; #else #error "No definition for shared_ptr found" #endif Second, the code uses std::tr1:: over boost:: to minimize dependencies on external libraries (even if the the libraries are widely used). Are these two solutions common? Are there better ones?

  • How can I search for an email using the zend framework?

    - by Ali
    Hi guys I need to build a functionality that involves searching through emails in an inbox for emails whose subjects match a certain user inputted keyword. SInce I'm using the zend framework I would like a solution that uses the zend framework libraries. Aside this I have noticed that the zend libraries are a bit limited with respect to my requirements for email handling. Is there any open library available in php which can be used for handling emails - when I mean handling emails I mean like: Ease to mark and flag emails Moving of emails from folder to folder. Parsing emails searching through emails SOrting emails etc - the stuff you would require if you wished to build a web client. EDIT ========= I'm looking for a generic solution here. The emails are in a regular email inbox on an IMAP server. I need a way to be able to read through and search for emails in the inbox using any specialized library to make it easier.

  • NET Framework Validation Library

    - by Kane
    As I see it most applications have a requirement for some form of validation and a number of fantastic free offerings are available (I.E., Fluent Validation, Validation Block, Spring, Castle Windsor, etc). My question is why does the .NET Framework not include any inbuilt validation libraries? I am aware the .NET Framework allows a developer the ability to build their own validation libraries/methods/etc. and anything provided as part of the .NET Framework would not always meet everyone’s needs. But surely something could have been included? ASP.NET has a minimal set of validators but these have not really been extended since .NET 2.0 was released.

  • Why does adding a reference to project targeting .NET Framework 4.0 fail?

    - by Malcolm Post
    We have two projects that are both class libraries. Project 1 is a VS 2008 project and targets the .NET Framework 3.5. Project 2 is a VS 2010 (release candidate) project that targets the .NET Framework 4.0. When I try to add a reference to Project 2 in Project 1, it fails with a less than informative error message. I know that if I change the target Framework for Project 2 to 3.5, then adding the reference will work. My question is, if I don't change the target frameworks, but convert Project 1 to VS 2010, will the referencing work? Stated another way, is there some inherent incompatiblity between class libraries targeting different framework versions, or is it failing for me because VS 2008 doesn't know about the 4.0 framework?

  • Include headers in header file?

    - by Mohit Deshpande
    I have several libraries made by myself (a geometry library, a linked list library, etc). I want to make a header file to include them all in one lib.h. Could I do something like this: #ifndef LIB_H_ #define LIB_H_ #include <stdio.h> #include <stdlib.h> #include <linkedlist.h> #include <geometry.h> .... #endif Then I could just reference this one library and actually reference multiple libraries. Is this possible? If not, is there a way around it?
