• Read XML from an XDocument with silverlight

  - by user625310

  Hi I have managed to load an XDocument with xml data from this link http://go.yr.no/go/e/main/http://www.yr.no/place/Norway/Telemark/Sauherad/Gvarv/forecast.xml. I am using C# and .Net in Blend and producing a web app (ie some of the normal .Net functions is not included in the silverlight plugin). I have researched this a lot but can not figure out: how to put the "text" in the link node in a string variable and how to all put the "-11" from ? in a array and link it to the "time from"? I think i have to use LINQ, but the stuff on MSDN and other tutorials is confusing and to general. huge thank in advance Regards Arnt I am sorry to ask such novice questions, but i have searched a lot. Also please excuse the typos, English is not my first language. Huge thank in advance Arnt

• MySQL: Limit output according to associated ID

  - by Jess

  So here's my situation. I have a books table and authors table. An author can have many books... In my authors page view, the user (logged in) can click an author in a tabled row and be directed to a page displaying the author's books (collected like this URI format: viewauthorbooks.php?author_id=23), very straight forward... However, in my query, I need to display the books for the author only, and not all books stored in the books table (as i currently have!) As I am a complete novice, I used the most simple query of: SELECT * FROM tasks_tb This returns the books for me, but returns every single value (book) in the database, and not ones associated with the selected author. And when I click a different author the same books are displayed for them...I think everyone gets what I'm trying to achieve, I just don't know how to perform the query. I'm guessing that I need to start using more advanced query clauses like INNER JOIN etc. Anyone care to help me out :)

• iPhone simulator app crashes when appending a string

  - by Franklyn Weber

  Hi, I'm a complete novice, so I'm probably missing something really easy, but I can't get my string appending to work. I add the 3rd character to typedDigit & it crashes - the method is called fine and typedDigit will get to 2 characters long. I think everything is declared properly in the header file. Code is - -(IBAction)digitPressed:(UIButton *)sender { NSString *digit = [[sender titleLabel] text]; // in this case, "0" - "9" if (userIsInMiddleOfTyping) { // typedDigit is already at least 1 character long typedDigit = [typedDigit stringByAppendingString:digit]; } else { // first character of typedDigit typedDigit = digit; userIsInMiddleOfTyping = YES; } } Many thanks for any help!

• Css Multiple background-color

  - by Khanh TO

  I'm a novice in Css and it's difficult to search for this specific case on the internet, so I post a question here. I'm working on an existing code base and I see something like this. li { background-color: #000 \9; background-color: rgba(0, 0, 0, 0); } I don't understand the meaning of \9. But it looks to me they are duplicates and I should remove one of them. Could you please explain the \9 and should I remove one of them? Thanks.

• Experiences with OpenLaszlo?

  - by itsmatt

  In a related question, I asked about Web Development. I came across something called OpenLaszlo yesterday and thought it looked interesting for doing some website development. The site has a bunch of good information on it and they've got some nice tutorials and such, but being a total novice (as far as web development goes), I'm wondering whether anyone here would recommend this. As I stated in my other question, this is a new world for me and there are a lot of directions I could go. Can you compare/contrast this and other web development you've done? Obviously, this is somewhat subjective, but I haven't heard much about it on SO and I'm hoping to get some opinions on this.

• What will be the setup process for website development?

  - by Vijay Shanker

  Hi, I want to create a simple site for my personal usage. And this only in python based technologies. So I want to get a expert oponian on this topic. What should i used as platform? I did a search for available options and found Django, grok, web2py and many more of these. Which one a novice use should use? If I choose to use only the basic python scripts then what option i have to work on? http://wiki.python.org/moin/WebBrowserProgramming. This link on python site confused me more, instead of solving my curiosity about the topic. Please give some pointer to accurate and easy to understand reading materials. I have got a idea of developing java based web applications using either spring-webmvc and struts. Can I relate Java process to python process for web development?

• Can Spring understand @Inject replacing Weld as a JSR-299 implementation?

  - by Thorbjørn Ravn Andersen

  I have noticed from several web pages that apparently Spring 3.0 supports @Inject from JSR-330. As we would really like to use JSR-299 syntax for dependency injection in our libraries for both web apps and stand-alone applications, and have alternatives to Weld, it would be nice if Spring could do this. Being a novice to Spring, I tried downloading the Spring Framework distribution and put all jars on the Eclipse build path. No Inject annotation so my existing test project using Weld did not compile. Can this be done with Spring? What do I need to do to get it running? (I am aware that Guice eventually will support this too. It is only in SVN for now, and if there is an official Spring release which can, that would be better.)

• Downloading and Reading

  - by Jan Evans

  First I am a complete novice and need answers in plain and simple terms. I am trying to get the users manual for my Samsung galaxy s4 phone. Samsung "help" sent me a link to click but when I received it it was in Spanish tho the doc I'd said "english". The Samsung support line timed me out because I couldn't type fast enough when I told them I received it in Spanish. I explored the translator and didn't see how to translate a doc. Asked Google how to get the manual they gave a different doc I'd and sent it to clipboards. How can I read it? Now what? Tried to send this message and asking me for a tag and I have no idea what that means so I just clicked one. That's why I need the manual so desperately. It would be so much easier for me to get a paper copy of it but they want

• What's causing "Unable to retrieve native address from ByteBuffer object"?

  - by r0u1i

  As a very novice Java programmer, I probably should not mess with that kind of things. Unfortunately, I'm using a library which have a method that accepts a ByteBuffer object and throws when I try to use it: Exception in thread "main" java.lang.NullPointerException: Unable to retrieve native address from ByteBuffer object Is it because I'm not using a non-direct buffer? edit: There's not a lot of my code there. The library I'm using is jNetPcap, and I'm trying to dump a packet to file. My code takes an existing packet, and extract a ByteBuffer out of it: byte[] bytes = m_packet.getByteArray(0, m_packet.size()); ByteBuffer buffer = ByteBuffer.wrap(bytes); Then it calls on of the dump methods of jNetPcap that takes a ByteBuffer.

• how to handle db concurrency in client-server application in C#?

  - by RAJ K

  I am developing an application in C# WPF which will have Client-Server architecture (Client will do products sales billing). I am novice in this area and I asked this question to start my development process. Click here to view question. So, ultimately I have selected MySQl, WCf & WPF. Now I have one silly question. Do i need to handle DB concurrency explicitly in my application (like 3 clients inserting data same time) or MySQl will handle this without any conflict? To accomplish my project i thought, I will create a service in WCf which will do DB queries from client application. Do you have any suggestion to improve my application performance.

• Random numbers from binomial distribution

  - by Sarah

  I need to generate quickly lots of random numbers from binomial distributions for dramatically different trial sizes (most, however, will be small). I was hoping not to have to code an algorithm by hand (see, e.g., this related discussion from November), because I'm a novice programmer and don't like reinventing wheels. It appears Boost does not supply a generator for binomially distributed variates, but TR1 and GSL do. Is there a good reason to choose one over the other, or is it better that I write something customized to my situation? I don't know if this makes sense, but I'll alternate between generating numbers from uniform distributions and binomial distributions throughout the program, and I'd like for them to share the same seed and to minimize overhead. I'd love some advice or examples for what I should be considering.

• Convert a string representation of a hex dump to a byte array using Java?

  - by ravigad

  I am looking for a way to convert a long string (from a dump), that represents hex values into a byte array. I couldn't have phrased it better than the person that posted the same question here: http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_21062554.html But to keep it original, I'll phrase it my own way: suppose I have a string "00A0BF" that I would like interpreted as the byte[] {0x00,0xA0,0xBf} what should I do? I am a Java novice and ended up using BigInteger and watching out for leading hex zeros. But I think it is ugly and I am sure I am missing something simple...

• How can I output the fitted values?

  - by zenbomb

  Sorry if this is a novice question, but I don't understand it. I am fitting a sigmoid curve to my data with glm(). This works, I can plot the output and I see a nice sigmoid curve. However, how do I get R to return the final values it has fit? As I understand it, R fits the data to logit(y) = b0 + b1x, but when I do > summary(glm.out) I only get Call: glm(formula = e$V2 ~ e$V1, family = binomial(logit), data = e) Deviance Residuals: 1 2 3 4 5 6 7 -0.00001 -0.06612 -0.15118 -0.34237 0.20874 0.08724 -0.19557 Coefficients: Estimate Std.

• adding org.springframework.test package to spring-2.5.6-SEC01.jar in netbeans

  - by John

  This is probably very simple, however I can't get this to work. I want to use AbstractDependencyInjectionSpringContextTest class which is in org.springframework.test package. This package is not included in Netbeans' spring library, so I want to add it. So what I have tried so far is: copy and paste "test" directory (downloaded from spring) into the Netbeans' spring-2.5.6-SEC01.jar file (copy it to org.springframework directory in that jar so I can use org.springframework.test to import it). If I go to project/libraries in Netbeans it is there, but when I try to import org.springframework.test.*; the autocomplition doesn't give me the option to choose test directory from org.soringframework package. create a new library which points to "test" directory and add it to the project- as there is no any jar file in "test" I'm not sure what path should I use to import it. I'm pretty sure this is something very simple but I'm still a novice and can't figure this out.

• Sum up values in SQL once all values are available

  - by James Brown

  I have events flowing into a MySQL database and I need to group and sum the events to transactions and store away into another table. The data looks like: +----+---------+------+-------+ | id | transid | code | value | +----+---------+------+-------+ | 1 | 1 | b | 12 | | 2 | 1 | i | 23 | | 3 | 2 | b | 34 | | 4 | 1 | e | 45 | | 5 | 3 | b | 56 | | 6 | 2 | i | 67 | | 7 | 2 | e | 78 | | 8 | 3 | i | 89 | | 9 | 3 | i | 90 | +----+---------+------+-------+ The events arrive in batches and I would like to create the transaction by summing up the values for each transid, like: select transid, sum(value) from eventtable group by transid; but only after all the events for that transid have arrived. That is determined by the event with the code e (b for the beginning, e for the end and i for varying amount of intermediates). Being a novice in SQL, how could I implement the requirement for the existance of the end code before the summing?

• How can I make a recursive version of my iterative method?

  - by user247679

  Greetings. I am trying to write a recursive function in Java that prints the numbers one through n. (n being the parameter that you send the function.) An iterative solution is pretty straightforward: public static void printNumbers(int n){ for(int i = 1; i <= n; i++){ System.out.println(i); i++; } As a novice programmer, I'm having troubles figuring out how a recursive version of this method would work. Any bright ideas? Thanks for reading my problem!

• User forms authentication in JSF

  - by Proton

  I'm a novice at JSF and I got a couple of questions concerning organizing user authentication there. 1) How can i redirect the registered user to a welcome page (for example welcome.xhtml)? I heard about using Filter or navigation-rule tag, but i didn't found a full-blown tutorial of how it works. 2) How can i tell the server that unauthorized users can access not only the login page but also the registration page? Is there an analog for ASP.NET web.config tag or something like this?

• How can I use computer vision to find a shape in an image?

  - by Ryan

  I have a simple photograph that may or may not include a logo image. I'm trying to identify whether a picture includes the logo shape or not. The logo (rectangular shape with a few extra features) could be of various sizes and could have multiple occurrences. I'd like to use Computer Vision techniques to identify the location of these logo occurrences. Can someone point me in the right direction (algorithm, technique?) that can be used to achieve this goal? I'm quite a novice to Computer Vision so any direction would be very appreciative. Thanks!

• Passing report values to a query

  - by Beavis

  I'm a novice with Microsoft Access as my background is mostly .NET. I'm sure what I'm trying to accomplish is dead simple but I need some direction. I have a report and a query. The query returns a single numeric value based on a single numeric criteria. Select total from table where id = [topic] I have placed a text box on my report so I can feed the id to this query and in return get the total. It seems like DLookUp is what I want but no matter how I construct it, I get an "#Error" in the text box when I run the report. Currently my DLookUp looks like this (I just hard-coded now for simplicity): =DLookUp("[total]","myquery","[topic] = 3") How can I pass a value from a field on my report to a query so I can return the query's single numeric value? Thanks.
