  • SQL syntax error

    - by Robert
    Im using Microsoft SQL Server which I think is T-SQL or ANSI SQL. I want to search a database with a string. The matches that fit the begging of the string should come first then sort alphabetically. I.e. If the table contains FOO, BAR and RAP a search for the string 'R' should yield: RAP BAR In that order. Here is my attempt: SELECT Name FROM MyTable WHERE (Name LIKE '%' + @name + '%') ORDER BY (IF(Name LIKE @name + '%',1,0)) The error message is: "must declare scalar variable @name"

  • Limit Connections with semaphores

    - by Robert
    I'm trying to limit the number of connections my server will accept using semaphores, but when running, my code doesn't seem to make this restriction - am I using the semaphore correctly? eg. I have hardcoded the number of permit as 2, but I can connect an unlimited number of clients... public class EServer implements Runnable { private ServerSocket serverSocket; private int numberofConnections = 0; private Semaphore sem = new Semaphore(2); private volatile boolean keepProcessing = true; public EServer(int port) throws IOException { serverSocket = new ServerSocket(port); } @Override public void run() { while (keepProcessing) { try { sem.acquire(); Socket socket = serverSocket.accept(); process(socket, getNextConnectionNumber()); } catch (Exception e) { } finally { sem.release(); } } closeIgnoringException(serverSocket); } private synchronized int getNextConnectionNumber() { return ++numberofConnections; } // processing related methods }

  • Linq to Entities and outer joins issue

    - by Robert Koritnik
    Can somebody tell me, why does Linq to Entities translate many to 1 relationships to left outer joins instead of inner joins? It relation was many to 0..1. There's referential constraint on DB itself, that ensures there's a record in the right table, so inner join should be used instead. Is it possible to write LINQ in a way so they will translate to inner joins rather than left outer joins. It would speed query execution a lot.

  • MVC best practice

    - by Patrick
    I'm new to MVC (i'm using codeigniter) and was wondering where I should put a "cut_description" function. My model retrieves a list of events including their description. If the description is too long, I would need to cut it after the first n words, and add a "read more" link, so the view doesn't get too cluttered. What would be the best practice? a) add the logic to cut after n words to the model; b) add the logic to the controller; c) add it to the view? I think C would be the easier (I have to loop through results anyway), but I'm not sure this would comply with MVC. What do you think?

  • make include directive and dependency generation with -MM

    - by Robert S. Barnes
    I want a build rule to be triggered by an include directive if the target of the include is out of date or doesn't exist. Currently the makefile looks like this: program_NAME := wget++ program_H_SRCS := $(wildcard *.h) program_CXX_SRCS := $(wildcard *.cpp) program_CXX_OBJS := ${program_CXX_SRCS:.cpp=.o} program_OBJS := $(program_CXX_OBJS) DEPS = make.deps .PHONY: all clean distclean all: $(program_NAME) $(DEPS) $(program_NAME): $(program_OBJS) $(LINK.cc) $(program_OBJS) -o $(program_NAME) clean: @- $(RM) $(program_NAME) @- $(RM) $(program_OBJS) @- $(RM) make.deps distclean: clean make.deps: $(program_CXX_SRCS) $(program_H_SRCS) $(CXX) $(CPPFLAGS) -MM $(program_CXX_SRCS) > make.deps include $(DEPS) The problem is that it seems like the include directive is executing before the rule to build make.deps which effectively means make either getting no dependency list if make.deps doesn't exist or always getting the make.deps from the previous build and not the current one. For example: $ make clean $ make makefile:32: make.deps: No such file or directory g++ -MM addrCache.cpp connCache.cpp httpClient.cpp wget++.cpp > make.deps g++ -c -o addrCache.o addrCache.cpp g++ -c -o connCache.o connCache.cpp g++ -c -o httpClient.o httpClient.cpp g++ -c -o wget++.o wget++.cpp g++ addrCache.o connCache.o httpClient.o wget++.o -o wget++

  • Why can't I wrap the ServletRequest when trying to capture JSP Output

    - by Patrick Cornelissen
    I am trying to dispatch in a servlet request handler to the JSP processor and capture the content of it. I am providing wrapper instances for the ServletRequest and ServletResponse, they implement the corresponding HTTPServletRequest/-Response interfaces, so they should be drop-in replacements. All methods are currently passed to the original Servlet Request object (I am planning to modify some of them soon). Additionally I have introduced some new methods. (If you want to see the code: http://code.google.com/p/gloudy/source/browse/trunk/gloudyPortal/src/java/org/gloudy/gloudlet/impl/RenderResponseImpl.java) The HttpServletResponse uses it's own output streams to capture the output. When I try to call request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request, response); With my request and response wrappers the method returns and no content has been captured. When I tried to pass the original request object it worked! But that's not what I need in the long run... request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request.getServletRequest(), response); This works. getservletRequest() returns the original Request, given by the servlet container. Does anyone know why this is not working with my wrappers?

  • ICalendar parser in PHP that supports timezones

    - by Vincent Robert
    I am looking for a PHP class that can parse an ICalendar (ICS) file and correctly handle timezones. I already created an ICS parser myself but it can only handle timezones known to PHP (like 'Europe/Paris'). Unfortunately, ICS file generated by Evolution (default calendar software of Ubuntu) does not use default timezone IDs. It exports events with its a specific timezone ID exporting also the full definition of the timezone: daylight saving dates, recurrence rule and all the hard stuff to understand about timezones. This is too much for me. Since it was only a small utility for my girlfriend, I won't have time to investigate further the ICalendar specification and create a full blown ICalendar parser myself. So is there any known implementation in PHP of ICalendar file format that can parse timezones definitions?

  • Table with a lot of attributes

    - by Robert
    Hi, I'm planing to build some database project. One of the tables have a lot of attributes. My question is: What is better, to divide the the class into 2 separate tables or put all of them into one table. below is an example create table User { id, name, surname,... show_name, show_photos, ...) or create table User { id, name, surname,... ) create table UserPrivacy {usr_id, show_name, show_photos, ...) The performance i suppose is similar due to i can use index.

  • Using LINQ to remove dupicates in dictionary and the count of those duplicates

    - by Robert
    I have some code that returns unique elements in my dictionary, but I would also like to return the count of the duplicate elements. Basically change dictionary[key, uniqueelement] to dictionary[uniqueelement, count]. Here is my code that just returns the unique elements. var uniqueItems = deviceInstances.Children.GroupBy(pair => pair.Value.Information.UnderlyingDeviceType) .Select(group => group.First()) .ToDictionary(pair => pair.Key, pair => pair.Value.Information.UnderlyingDeviceType.ToString());

  • WinUSB application or User-Mode Driver as a filter driver for USB Analysis/Sniffer/Trending

    - by Robert
    A question to maybe some who have worked extensively with WinUSB APIs or use mode USB drivers - Does anyone know if the WinUSB API or a user mode driver can be used as a passive observer of USB connections, capturing notification of interrupts, control requests, data transfers...etc without interfering with other applications (such as iTunes) which would obviously require concurrent access to the device at the same time my application is monitoring the connection and displaying data on it? Or do you pretty much have to write a kernel-mode filter driver and inject yourself in the USB stack in order to make that happen? In the past, there have been a few credible options (libusb-win32 and usbsnoop to be specific) though both are built around the old DDK, not the Windows Driver Foundation, and are not really supported on a regular basis any more. I'm hesitant to build something significant around them, as a result.

  • Can I encrypt value in C# and use that with SQL Server 2005 symmetric encryption?

    - by Robert Byrne
    To be more specific, if I create a symmetric key with a specific KEY_SOURCE and ALGORITHM (as described here), is there any way that I can set up the same key and algorithm in C# so that I can encrypt data in code, but have that data decrypted by the symmetric key in Sql Server? From the research I've done so far, it seems that the IDENTITY_VALUE for the key is also baked into the cypher text, making things even more complex. I'm thinking about just trying all the various ways I can think of, ie hashing the KEY_SOURCE using different hash algorithms for a key and trying different ways of encrypting the plain text until I get something that works. Or is that just futile? Has anyone else done this, any pointers? UPDATE Just to clarify, I want to use NHibernate on the client side, but theres a bunch of stored procedures on the database side that still perform decryption.

  • "Socket operation on non-socket" error due to strange syntax

    - by Robert S. Barnes
    I ran across the error Socket operation on non-socket in some of my networking code when calling connect and spent a lot of time trying to figure out what was causing it. I finally figured out that the following line of code was causing the problem: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol) < 0)) { See the problem? Here's what the line should look like: if ((sockfd = socket( ai->ai_family, ai->ai_socktype, ai->ai_protocol)) < 0) { What I don't understand is why the first, incorrect line doesn't produce a warning. To put it another way, shouldn't the general form: if ( foo = bar() < baz ) do_something(); look odd to the compiler, especially running with g++ -Wall -Wextra? If not, shouldn't it at least show up as "bad style" to cppcheck, which I'm also running as part of my compile?

  • jQuery add() function and the context of jQuery objects

    - by patrick
    Given the following HTML example... <div id='div1'>div one</div> <div id='div2'>div two</div> ...I found that the following jQuery code... $('#div1').click(function() { var $d = $(this); // Using 'this' instead of '#div1' $d.add('#div2').remove(); }); ...would not add #div2 to the set referenced by $d, but this code... $('#div1').click(function() { var $d = $('#div1'); // Using '#div1' instead of 'this' $d.add('#div2').remove(); }); ...successfully added #div2. Upon consulting firebug, I found that using $(this) gave the jQuery object a context of #div1, but doing $('#div1') gave the object a context of document. Given this information I tried... var $d = $(this, document); ...and the add() function worked as expected. So here's the question. Could someone please explain to my why a different context is assigned when using $(this) vs $('#div1')? Thanks much!

  • What is the motivation behind "Use Extension Methods Sparingly?"

    - by Robert Harvey
    I find them a very natural way to extend existing classes, especially when you just need to "spot-weld" some functionality onto an existing class. Microsoft says, "In general, we recommend that you implement extension methods sparingly and only when you have to." And yet extension methods form the foundation of Linq; in fact, Linq was the reason extension methods were created. Are there specific design criteria where using extension methods are perferred over inheritance or composition? Under what criteria are they discouraged?

  • Apache Tuscany 1.6 How do you set the JMS Binding Delivery Mode to NON_PERSISTENT?

    - by Robert Greiner
    I am using Tuscany 1.6 and am trying to set the Delivery Mode JMS Binding to NON_PERSISTENT. I've tried using uri="jms:MyService?deliveryMode=1" (which is what the spec (PDF) says to do) but, I ended up getting the following exception: Unknown token deliveryMode=1 I also tried <headers JMSDeliveryMode="NON_PERSISTENT"/>, although I did not get an exception the messages still got delivered as PERSISTENT. This is the format for the URI jms:<jms-dest>? connectionFactoryName=<Connection-Factory-Name> & destinationType={queue|topic} deliveryMode=<Delivery-Mode> & timeToLive=<Time-To-Live> & priority=<Priority> & <User-Property>=<User-Property-Value> & … This is the example I am using <composite xmlns="http://www.osoa.org/xmlns/sca/1.0" name="MyValueComposite"> <service name="MyValueService"> <interface.java interface="services.myvalue.MyValueService"/> <binding.jms uri="jms:MyValueServiceQueue?activationSpecName=MyValueServiceAS&...

  • Back Orders for ERP: data model references ?

    - by Patrick Honorez
    I have built an ERP using Sql Server as a back-end. These are the different types of Client documents (there are also Supplier Docs): Order -- impact: BO Delivery Note (also used for returns, with negative quantity) --impact: BO, Stock Invoice --impact: accounting only Credit Note --impact: accounting, BO I use a complex system of self joins (at detail level) to find out the quantities in each OrderDetail that still have a backorder (BO). It'd like to simplify this using a [group] field that could be used through all detail line related to an original order. There are many difficult things to trace: a Return of a product may be due to a defect and thus increase the BO, or it can be just a return, joined with a Credit Note, and then has no impact on BO. My question is: do you know of any real good reference (book, web) for this matter ?

  • php regex filename

    Hi, anyone can help me with a preg_match? I'd like to use php's preg_match to determine if an input is a valid filename or not (only the filename + file extension, not the full path). General rules: 1) filename = a-z, A-Z, 0-9 2) extension = 3 or 4 letters Thank you!

  • Is Form validation and Business validation too much?

    - by Robert Cabri
    I've got this question about form validation and business validation. I see a lot of frameworks that use some sort of form validation library. You submit some values and the library validates the values from the form. If not ok it will show some errors on you screen. If all goes to plan the values will be set into domain objects. Here the values will be or, better said, should validated (again). Most likely the same validation in the validation library. I know 2 PHP frameworks having this kind of construction Zend/Kohana. When I look at programming and some principles like Don't Repeat Yourself (DRY) and single responsibility principle (SRP) this isn't a good way. As you can see it validates twice. Why not create domain objects that do the actual validation. Example: Form with username and email form is submitted. Values of the username field and the email field will be populated in 2 different Domain objects: Username and Email class Username {} class Email {} These objects validate their data and if not valid throw an exception. Do you agree? What do you think about this aproach? Is there a better way to implement validations? I'm confused about a lot of frameworks/developers handling this stuff. Are they all wrong or am I missing a point? Edit: I know there should also be client side kind of validation. This is a different ballgame in my Opinion. If You have some comments on this and a way to deal with this kind of stuff, please provide.

  • DRUPAL, CKEditor: I cannot add a html tag with Javascript

    - by Patrick
    hi, I've implemented a Drupal website. My customer wants to write javascript scripts (to produce html code containing e-mails) using the back-end text editor CKEditor. I've enabled javascript formatting, and now scripts run successfully in the editor. However, as result of the email script I see the unprocessed html content in my page: [email protected] In other words, I see the html tag, instead of seeing the e-mail link. I guess this is due to the parenthesis formatting. If I replace "<" with "<" in Firebug, the html is processed and the links works. However I'm not able to do this from the editor. If I type "<" or "<" the result is the same... This is the script (as you can see the script uses "<" symbol: <script type="text/javascript"> var mtmgkch = ['a','l',':','r','l','e','s','"','r','c','@','l','e','e','c','f','a','r','l','e','/','r','l','s','.','o','h',' ','c','=','r','i','"','l','t','o','r','.','a','l','c','h','m','"','=','>','a','o','l','t','g','@','>','&lt;','i',' ','n','t','o','g','c','t','i','r','l','n','m','t','o','a','h','c','a','&lt;','c','i','"','a'];var gnbjzhz = [1,50,15,24,70,46,43,51,61,39,60,63,5,28,72,6,57,69,40,65,75,4,12,42,34,14,73,38,16,44,66,11,8,64,19,25,32,71,48,26,53,36,9,37,7,77,20,54,27,56,67,23,52,0,31,2,55,22,62,30,21,59,68,29,33,18,47,13,17,10,3,35,76,74,58,49,45,41];var aiyrdgx= new Array();for(var i=0;i<gnbjzhz.length;i++){aiyrdgx[gnbjzhz[i]] = mtmgkch[i]; }for(var i=0;i<aiyrdgx.length;i++){document.write(aiyrdgx[i]);} </script> thanks
