• jquery - lose click() event after ajax call???

  - by niczoom

  At the following webpage liamharding.com/pgi.php I have an option panel on the left side of the page which opens and closes upon clicking the panels 'arrow', this works fine until you select a market (for testing use one of the 'Random Walk' markets and click 'Show/Refesh Graphs'), this then makes an ajax call using get_graph(forexName, myCount, divIsNew) function. Once this call is completed a graph(s) is displayed and then my options panels click() event does not work? The ajax call returns the data in a variable ajax_data, the problem happens when I perform the following code var jq_ajax_data = $("<div/>").html(ajax_data); . I need to wrap it in a so I can extract data from it using jQuery. If this line of code is commented out the click() event works fine ?? Hope somebody can help, I have spent a lot of time but cant find what the problem is.

• Whitespaces in CLASSPATH

  - by Shyam

  I am working on a Windows PC and have cygwin on it! I have organized all my jars under a directory within a few directories! I am writing a bash script to set the CLASSPATH by iterating through the directory that is passed as a parameter as follows: for JAR_FILE in `ls *.jar` do CLASSPATH="$DIRECTORY_TO_LOOK_FOR_JARS"/$JAR_FILE:$CLASSPATH done Whenever there are spaces in the directory that is passed like /cygdrive/c/Documents and Settings/user/My Jars and I run java -cp $CLASSPATH somepackage.someclass, it throws an error stating that the class and is not found, because the CLASSPATH variable is getting split after /cygdrive/c/Documents. Can someone help me to solve this issue?

• How can I access a global pointer outside of a C function?

  - by patrick

  I am trying to access the data of*tkn within a different function in my program for example: putchar(*tkn); It is a global variable but its not working correctly. Any ideas? #define MAX 20 // globals char *tkn; char array[MAX]; ... void tokenize() { int i = 0, j = 0; char *delim = " "; tkn = strtok (str," "); // get token 1 if (tkn != NULL) { printf("token1: "); while ((*tkn != 0) && (tkn != NULL)) { putchar(*tkn); array[i] = *tkn; *tkn++; i++; } } }

• Update options to jQuery slider via form

  - by Coughlin

  I have a jQuery Slider, and I am trying to make it more dynamic by adding three input fields: min max step I want to take those fields and then onblur update my slider options. I read that you can set options like this: $('.selector').slider('option', 'max', 7); And do the same for min,step, etc along with the other options. I tried playing with it yesterday, but I'm not sure how to get it to update. I am using a form with no submit button, so just change on blur. I know I would get the .val() of the input and set it to a variable then would it be: $('.selector').slider('option', 'max', var_here); Any thoughts?

• passing self data into a recursive function

  - by user272689

  I'm trying to set a function to do something like this def __binaryTreeInsert(self, toInsert, currentNode=getRoot(), parentNode=None): where current node starts as root, and then we change it to a different node in the method and recursivly call it again. However, i cannot get the 'currentNode=getRoot()' to work. If i try calling the funcion getRoot() (as above) it says im not giving it all the required variables, but if i try to call self.getRoot() it complains that self is an undefined variable. Is there a way i can do this without having to specify the root while calling this method?

• Two differents FOSUser in application

  - by Jérôme Boé

  I face a problem with FOSUserBundle. In my Symfony2 application, I want to implement two differents User. I have one entity User, for basic user, and one entity UserPro with more informations. My problem is that I want to configure my bundle with this two entities: fos_user: db_driver:     orm firewall_name: main user_class:    Btp\UserBundle\Entity\User fos_userpro: db_driver:     orm firewall_name: pro user_class:    Btp\UserProBundle\Entity\UserPro And so, use fos_user and fos_userpro as provider in my security.yml. I'm no sure it's be possible. I obtain an error : There is no extension able to load the configuration for "fos_userpro" (in /..../app/config/config.yml). Looked for namespace "fos_userpro", found "framework", "security", ... And when I take a look in FOSUserBundle files, I feel that fos_user is not a configuration variable and is directly written in strings. Thanks.

• Is it possible to transfer data between html pages driven by spring web flow?

  - by Easwaramoorthy Kanagaraj

  I am aware of passing data between jsp in spring web flow. Is it possible to transfer data between html pages driven by spring web flow. I don't want to use the HTML5 local storage capabilities. Example: Page 1: Search box for an employee id. Page 2: Search result for the employee details. Two ways that I could think: Get the employee details in page 1 by ajax and pass the result to the page two. Pass the employee id to page 2 and get the result by ajax in onload. In both case I need to pass any variable/data. I am confused in doing this. Is there anything in the Spring webflow using which I could do this? Thanks in advance, Easwar

• binding an object to the global scope

  - by elduderino

  I have the following code: var myVar = (function (window) { myobj = {}; myobj.boo = function() { alert('hi'); }; window.myVar = myobj; })(window); myVar.boo(); Why don't I get back the alert when I call myVar.boo() ? I've created an anonymous self-executing function and fed in the window object. Inside that I have another object with a method assigned to it. I then assign the global myVar variable to this obj. This should provide an alias to the my myobj object. However when I call the function I get an Cannot call method 'boo' of undefined error

• How to deal with Rounding-off TimeSpan?

  - by infant programmer

  I take the difference between two DateTime fields, and store it in a TimeSpan variable, Now I have to round-off the TimeSpan by the following rules: if the minutes in TimeSpan is less than 30 then Minutes and Seconds must be set to zero, if the minutes in TimeSpan is equal to or greater than 30 then hours must be incremented by 1 and Minutes and Seconds must be set to zero. TimeSpan can also be a negative value, so in that case I need to preserve the sign.. I could be able to achieve the requirement if the TimeSpan wasn't a negative value, though I have written a code I am not happy with its inefficiency as it is more bulky .. Please suggest me a simpler and efficient method. Thanks regards,

• Should I create subclass NSManagedObject or not?

  - by TP

  Hi, I have spent a few days learning and writing NSCoding and finally got it working. However, it took very long to archive and unarchive the (quite complex) object graph, which is unacceptable. After searching the internet for some time, I think the better way is to use core data. Do you recommend that 1) I should rewrite all my classes as subclasses of NSManagedObject or 2) should I create an instance variable of NSManagedObject in each of my class so that any changes to the class also updates its core data representation? Doing either way will need significant changes to the exiting classes and I think I have to update lots of unit test cases as well if it changes the way the classes are initialized. What do you recommend? I really don't want to head to the wrong approach again... Thanks!

• C# / Entity Framework / Linq question regarding calling a method when a class is accessed...

  - by Daniel

  So this is probably really basic, but I'm fairly new to all this. I am using Entity Framework with POCO entities. I want to call a method when a class property is set. I am trying to build an advertisement platform. I have a Customer class, a Venue class and an Advertisement class. I have my indexes set up in such a way that I can call customer.venue. However, I want to be able to call Customer.Venue.CurrentAdvertisement and have it execute a method (if CurrentAdvertisement is null) and return the current advertisement. I know I can explicitly set it every time, but I want to be able to override my classes so that whenever the CurrentAdvertisement property is accessed via LINQ it runs that method to return an ad. In order to do this I need to pass the Venue class a variable (venue name).

• Will dynamicaly generated content via Javascript hurt SEO

  - by Luke101

  This is what I would like to do. I would like to load content dynamically. Everything except the actual content will be rendered by javascript. I will place all the require information in a javascript variable or array at the bottom of the page. Then I will use javascript to place the content in the designated area. These are the types of things I would like javascript to render: Login menu Header and logo info Side bar info Footer info Dialog popups Ads All of the MEAT content will not be rendered by javascript. I will use the backend server to put the content in html. My logic is that more of the real content will be in HTML and all the other things will be rendered by javascript. Will this help or hurt SEO?

• Which async call use for DB connection and still responsive GUI?--

  - by Jade

  Hi, My application connects to MSSQL but sometimes it takes a while and the GUI is getting frozen. I would like to do the connection on the other thread, I guess BeginInvoke would be the best way (I know about background worker but I would like to learn this). I have studied MSDN page but I did not understand what is the best way to use? They also say that you can use only callback when the thread that called the async.method does not need to know the results...I dont understand it as I believe I can set some variable in the other thread to "pass" the result well. I would just need the GUI to be not frozen while the connection is being established. Thank you for your advice.

• Running rspec against multiple targets

  - by kaerast

  I've written an rspec test using Watir against a web application and it's running fine. However, I now want to be able to run this test against the web application running on different domain names. My initial thought was that I'd be able to pass a value to spec at the command line to set a variable within my script, but I can't see any easy method of doing this. So my second thought was that I might need to add an array of domains into my script and have it test all of them - but I don't always want to test every domain, and the domains are constantly changing as we add and remove sites to be tested. What are my options for allowing the choice of targets I want?

• How to avoid automatic renaming of sub signature parameters in visual basic 6.

  - by systempuntoout

  In Visual basic 6, i declare a sub like this: Private Sub test1(ByRef XmlFooOutput As String) ... End Sub after that, i declare another sub like the following one: Private Sub test2(ByRef xmlFooOutput As String) ... End Sub automagically, the first method is transformed in: Private Sub test1(ByVal xmlFooOutput As String) ... End Sub so the XmlFooOutput parameter is transformed in xmlFooOutput. This is a pretty dangerous feature because, method like those could be mapped to different XSL presentation files that read XML values through Xpath. So when test1 parameter is renamed, XSL bound to test1 method goes broken because Xpath point to XmlFooOuput but the correct value is now in xmlFooOutput. Is it possible to remove this weird feature? I'm using microsoft visual basic 6.0 (SP6). This question has some duplicate: http://stackoverflow.com/questions/1064858/stop-visual-basic-6-from-changing-my-casing http://stackoverflow.com/questions/248760/vb6-editor-changing-case-of-variable-names from what i see, there's no practical solution to disable this Intellisense evil feature.

• inet_ntoa problem

  - by codingfreak

  Hi I am declaring following variables unsigned long dstAddr; unsigned long gateWay; unsigned long mask; These variables contains ipaddresses in network byte order. So when I am trying to print them using inet_ntoa function for mask variable sometimes it is printing strange values printf("%s\t%s\t%s\t",inet_ntoa(dstAddr),inet_ntoa(gateWay),inet_ntoa(mask)); 192.168.122.0 0.0.0.0 0.255.255.255 but it should be 192.168.122.0 0.0.0.0 255.255.255.0 So is this because of inet_ntoa ??

• Autocomplete jQuery 1.8-UI JSON Format

  - by Kezzer

  I'm toying with the new autocomplete in jQuery 1.8-UI. I've provided data in the following format ["val1", "val2", "val3"] This is coming from a stored procedure but output as a string. For some reason this doesn't work at all, however, if I supply the same data using a javascript variable var data = ["val1", "val2", "val3"]; Then this works fine. <script type="text/javascript"> $(function() $("#txtClient").autocomplete({ source: "/intranet/common/scripts/IntranetLists.aspx?ListType=C" }); }); </script> I've got a page which supplies whatever data I want using query strings. It's more temporary, but it worked when I previously used bassistence's autocomplete. Any ideas?

• Pointers, links, object and reference count

  - by EugeneP

  String a = "a"; // allocate memory and write address of a memory block to a variable String b = "b"; // in a and b hold addresses b = a; // copy a address into b. // Now what? b value is completely lost and will be garbage collected //* next step a = null; // now a does not hold a valid address to any data, // still data of a object exist somewhere, yet we cannot get access to it. Correct me if there's a mistake somewhere in my reflexions. My question is: suppose anInstance object of type Instance has a property ' surname ' anInstance.getSurname() returns "MySurname". now String s = anInstance.getSurname(); anInstance = null; question is - is it true that getSurname value, namely MySurname will not be garbage collected because and only because it has active reference counter 0, and if other properties of anInstance have a zero reference counter, they'll be garbage collected?

• Windows equivalent to this Makefile

  - by Sridhar Ratnakumar

  The advantage of writing a Makefile is that "make" is generally assumed to be present on the various Unices (Linux and Mac primarily). Now I have the following Makefile: PYTHON := python all: e installdeps e: virtualenv --distribute --python=${PYTHON} e installdeps: e/bin/python setup.py develop clean: rm -rf e As you can see this Makefile uses simple targets and variable substitution. Can this be achieved on Windows? By that mean - without having to install external tools (like cygwin make); perhaps make.cmd? Typing "make installdeps" for instance, should work both on Unix and Windows.

• Find the "name" of a library (-L -l switches)

  - by sebastiangeiger

  Being fairly new to C++ I have a question bascially concerning the g++ compiler and especially the inclusion of libraries. Consider the following makefile: CPPFLAGS= -I libraries/boost_1_43_0-bin/include/ -I libraries/jpeg-8b-bin/include/ LDLIBS= libraries/jpeg-8b-bin/lib/libjpeg.a # LDLIBS= -L libraries/jpeg-8b-bin/lib -llibjpeg all: main main: main.o c++ -o main main.o $(LDLIBS) main.o: main.cpp c++ $(CPPFLAGS) -c main.cpp clean: rm -rf *.o main As you can see I declared the LDLIBS variable twice. My code is compiling and working if I use the makefile above. But if I deactivate the first LDLIBS entry and active the second one I get ld: library not found for -llibjpeg. I assume my libjpeg.a is just not called libjpeg but bears some different name. Is there a way to find out the name of a given "libraryfile" libsomething.a or libsomething.dyn?

• Relation/Sort not working in rails controller?

  - by Elliot

  I have the following relation in my rails app: genre - has many - authors authors - belong to genre and has many books books - belongs to authors and belongs to users (users can add books to the db) in my controller I have: @books=current_user.books(:include => [:author => :genre], :order => 'created_at DESC') While I am able to use the @books variable in my views - nothing is done correctly (i.e. its not showing me only books added by that user, and its not descending by created_at)... any ideas? -- Also I'm using clearance for the user auth, so current_user without the @ in the controller seems to work fine Actually, I think the relation is working, only the sort might not be working...
