  • Flot Pie Chart using Ajax, Php and MySql

    - by Neriza Almirol
    Good Day! Can you help me? I have a problem getting values from database. I want to control the legend. I've been googling the best approach for the pie chart, but still looking for the best answer for my problem. It's easy to query the data from the database, but I want to show it using the flot pie chart and I need it for statistic reports. From database, I need to get the percentage of Female and Male followers and separate it according to age groups. The data (dateOfbirth) is available from our database using facebook integration. Can you give me an example using Ajax, Php and MySql? Thank you! :) $.plot($("#graph_3"), graphData, { series: { pie: { show: true } }, grid: { hoverable: true, clickable: true } }); $("#graph_3").bind("plothover", pieHover); $("#graph_3").bind("plotclick", pieClick);

  • Conflicting PACKAGE_NAME and other macros when using autotools.

    - by baol
    When using autotools (with a config.h file) for both a library and a software built on that library the compiler complains about a redefinition of some macros (PACKAGE_NAME, PACKAGE_TARNAME and so on). How can I prevent this? The config.h file is needed in the library to propagate it's setting to the software that use it. Right now I have a wrapper script library_config.h that includes the original config.h and provides defaults when the user is not using autotools, but even undefining the macros in that package I get the redefinition warning from gcc. #ifndef LIB_CONFIG_H #define LIB_CONFIG_H #ifdef HAVE_CONFIG_H # include "config.h" # undef PACKAGE # undef PACKAGE_BUGREPORT # undef PACKAGE_NAME # undef PACKAGE_STRING # undef PACKAGE_TARNAME # undef PACKAGE_VERSION # undef VERSION #else # if defined (WIN32) # define HAVE_UNORDERED_MAP 1 # define TR1_MIXED_NAMESPACE 1 # elif defined (__GXX_EXPERIMENTAL_CXX0X__) # define HAVE_UNORDERED_MAP 1 # else # define HAVE_TR1_UNORDERED_MAP 1 # endif #endif #endif I believe the best option would be to have a library without that macros: How can I avoid the definition of PACKAGE, PACKAGE_NAME and so on in the library when using autotools?

  • Counting texels using a fragment shader

    - by Brett
    Hi, I have two textures generated using a fragment shader. I want to be able to count the number of texels in each texture that are above some colour intensity. My question is how can this be done? My initial thought is to count these texels using the fragment shader before generating the texture. However, this would require some sort of global counter. I can't use occlusion queries because the textures are created from other textures. I'm using OpenGL 2.1. Any ideas appreciated. Thanks

    - by Teerasej
    I am using Flex builder 3, BlazeDS, and Java with Spring and Hibernate framework. I using the remote object to load a string from spring's configuration files. But in testing, I found this fault event like this: RPC Fault faultString="java.lang.NullPointerException" faultCode="Server.Processing" faultDetail="null" I have checked the configuration in remote-config.xml and services-config.xml. But it looks good. Some people have talked about this problem around the Internet and I think you can help me and them. I am using these environment: Flex Builder 3 BlazeDS 3.2.0 JBoss server Full stacktrace: [RPC Fault faultString="java.lang.NullPointerException" faultCode="Server.Processing" faultDetail="null"] at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::faultHandler()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\rpc\AbstractInvoker.as:220] at mx.rpc::Responder/fault()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\rpc\Responder.as:53] at mx.rpc::AsyncRequest/fault()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\rpc\AsyncRequest.as:103] at NetConnectionMessageResponder/statusHandler()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\messaging\channels\NetConnectionChannel.as:569] at mx.messaging::MessageResponder/status()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\messaging\MessageResponder.as:222]

  • Using generics with XmlSerializer

    - by MainMa
    Hi, When using XML serialization in C#, I use code like this: public MyObject LoadData() { XmlSerializer xmlSerializer = new XmlSerializer(typeof(MyObject)); using (TextReader reader = new StreamReader(settingsFileName)) { return (MyObject)xmlSerializer.Deserialize(reader); } } (and similar code for deserialization). It requires casting and is not really nice. Is there a way, directly in .NET Framework, to use generics with serialization? That is to say to write something like: public MyObject LoadData() { // Generics here. XmlSerializer<MyObject> xmlSerializer = new XmlSerializer(); using (TextReader reader = new StreamReader(settingsFileName)) { // No casts nevermore. return xmlSerializer.Deserialize(reader); } }

  • Winforms, creating padding when using Dock properties.

    - by Zka
    How do I add padding, or some space between the textboxes when using dockstyle.top property? for(int i =0; i< 10; i++) { textboxes[i] = new TextBox(); textboxes[i].Dock = DockStyle.Top; mypanel.Controls.Add(textboxes[i]); } The code above puts textboxes right beneath each other. Can't figure this out without using mass panels or fixed positioning. How to do the following? 1) I would like to add around 10-20pixels between boxes. 2) How to change size (height,width) of the textboxes, since when using dockstyle.top it ignores the size commands ?

  • How to preselect nodes using jsTree jQuery plug-in

    - by Ed Schembor
    I am using the jsTree jQuery plug-in with its "Checkbox" plug-in and using an async http request to lazy-load each level of the tree. All works great, except that I cannot get the tree to pre-select certain nodes after the first level. I am using the "selected" attribute to provide an array of ID's to preselect. ID's in the top level of the tree are correctly pre-selected. However, ID's in lower levels of the tree are not selected when the level loads. Am I missing something? Here is the constructor code: $(sDivID).tree( { data : { async : true, opts : {url : sURL} }, plugins:{ "checkbox" : {three_state : false} }, selected : myArrayOfIDs, ui:{ theme_name : "checkbox", dots : false, animation : 400 }, callback : { beforedata : function(NODE, TREE_OBJ) { return { id : $(NODE).attr("id") || 0, rand : Math.random().toString() } } } } )

  • accessing $_SESSION when using file_get_contents in PHP

    - by hairdresser-101
    I am basic - intermediate developer using php and am a little stumped as to what I have found. I need some help in understanding how to alleviate this issue: I have a page called send.email.php which sends an email - pretty simple stuff - I pass an order id, it creates job request and sends it out. This works fine when used in the context I developed it (Use javascript to make an AJAX call to the URL and pass the order_id as a query parameter) I am now trying to reuse the exact same page in another application however I am calling it using php file_get_contents($base_url.'admin/send.email.php?order_id='.$order_id). When I call the page this way, the $_SESSION array is empty isempty() = 1. Is this because I am initiating a new session using file_get_contents and the values I stored in the $_SESSION on login are not available to me within there? Any help? Thanks

  • How to generate a client certificate using a third party CA-NOT Self Signed CA

    - by Bryan
    I am trying to trying to export a client certificate for use with a web browser. The goal is to restrict access using the <Location directive to the admin area. I have seen numerous tutorials on using self signed CAs. How would you do this using a third party? 1) Do I need to include the CA in the client pfx if it is a trusted root CA? I have seen both examples. Without CA: openssl pkcs12 -export -inkey KEYFILENAME -in CERTFILEFILENAME -out XXX.pfx With CA: openssl pkcs12 -export -in my.crt- inkey my.key -certfile my.bundle -out my.pfx 2) Do I need to still include SSLCACertificateFile for trusted CA in the httpd.conf setup? SSLVerifyClient none SSLCACertificateFile conf/ssl.crt/ca.crt <Location /secure/area> SSLVerifyClient require SSLVerifyDepth 1 </Location> http://www.modssl.org/docs/2.8/ssl_howto.html#ToC8

  • Darkening UIView while flipping over using UIViewAnimationTransitionFlipFromRight

    - by Alexander Repty
    I'm using a standard animation block to flip over from one view to another, like this: [UIView beginAnimations:@"FlipAnimation" context:self]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:NO]; [UIView setAnimationBeginsFromCurrentState:NO]; [containerView exchangeSubviewAtIndex:1 withSubviewAtIndex:0]; [UIView commitAnimations]; During the animation's course, the "from" view darkens as it begins to flip over. Since I'm using nearly identical views on both sides which don't cover the whole view (it's meant to represent a physical card being flipped over), this looks absolutely horrible. Using [UIColor clearColor] as the backgroundColor property for every associated UIView didn't help one bit as transparent areas seem to get darkened as well. Any ideas on how I could get rid of this darkening effect?

  • Error 2006: "MySQL server has gone away" using Python, Bottle Microframework and Apache

    - by Jamie
    After accessing my web app using: - Python 2.7 - the Bottle micro framework v. 0.10.6 - Apache 2.2.22 - mod_wsgi - on Ubuntu Server 12.04 64bit; I'm receiving this error after several hours: OperationalError: (2006, 'MySQL server has gone away') I'm using MySQL - the native one included in Python. It usually happens when I don't access the server. I've tried closing all the connections, which I do, using this: cursor.close() db.close() where db is the standard MySQLdb.Connection() call. The my.cnf file looks something like this: key_buffer = 16M max_allowed_packet = 128M thread_stack = 192K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP #max_connections = 100 #table_cache = 64 #thread_concurrency = 10 It is the default configuration file except max_allowed_packet is 128M instead of 16M. The queries to the database are quite simple, at most they retrieve approximately 100 records. Can anyone help me fix this? One idea I did have was use try/except but I'm not sure if that would actually work. Thanks in advance, Jamie

  • Using Kate with Simple Build Tool (SBT)

    - by Stefan
    Hello I am working with the Kate editor based on the lack of other good tools for Scala development, I am also using IntelliJ however it still has some bugs, and are slow enough to make me impatient. I have just startet using both Kate and SBT, and in that regard I have a little challenge I hope there is an answer for out there on "The Internet". I am using the standard "Build plugin" in Kate and has changed the commands from make to sbt. This works fine, and I am also getting a error report when the sbt fails during compile time. However I really wish to know if it is possible to integrate the compile errors into Kate such that it would be shown under "Errors and Warnings" instead of just in the output tab, where I have to do a manual search for the compile errors. Im guessing that it has something to do with the format of the output, if that is the case maybe it is "just" a smaller adjustment I need to make to the parsing language.

  • Securely Storing Optional Entropy While Using DPAPI

    - by Changeling
    So I am trying to store the symmetric key using DPAPI. All is well and great, but what to do with the entropy? This answered question here really doesn't provide enough insight. It seems like a slippery slope - I could use the machine store to store the entropy but then what prevents someone from getting at that as well? Note: I am storing the current key using the User Scope. So my question is - what is the best way to store the entropy using DPAPI?

  • Certificate Information from WCF Service using Transport security mode

    - by Langdon
    Is there any way to pull information about which client certificate was used inside of my web service method when using <security mode="Transport>? I sifted through OperationContext.Current but couldn't find anything obvious. My server configuration is as follows: <basicHttpBinding> <binding name="SecuredBasicBindingCert"> <security mode="Transport"> <message clientCredentialType="Certificate" /> </security> </binding> </basicHttpBinding> I'm working with a third party pub/sub system who is unfortunately using DataPower for authentication. It seems like if I'm using WCF with this configuration, then I'm unable to glean any information about the caller (since no credentials are actually sent). I somehow need to be able to figure out whose making calls to my service without changing my configuration or asking them to change their payload.

  • How can I electronically transfer money to another account using Bank Transfer (BACS)

    - by Mooktakim Ahmed
    I'm working on a project where we collect payments from users using credit/debit/PayPal payments. The service is taking payments from users on behalf of a 3rd party organisation. Once we take the payment, minus fees, we want to transfer the amount to the organisations bank account. For now, what we can do is pay the organisation using Online Banking BACS bank transfer. But I would like to know if there is a way to do this automatically using an API. If we need to somehow register the 3rd parties bank account details before making transfers, this is fine. We just want to automate the whole process, since at the moment the transfer is a manual step. Are there any gateways or APIs I can use for this? In the UK?

  • Best practise when using httplib2.Http() object

    - by tomaz
    I'm writing a pythonic web API wrapper with a class like this import httplib2 import urllib class apiWrapper: def __init__(self): self.http = httplib2.Http() def _http(self, url, method, dict): ''' Im using this wrapper arround the http object all the time inside the class ''' params = urllib.urlencode(dict) response, content = self.http.request(url,params,method) as you can see I'm using the _http() method to simplify the interaction with the httplib2.Http() object. This method is called quite often inside the class and I'm wondering what's the best way to interact with this object: create the object in the __init__ and then reuse it when the _http() method is called (as shown in the code above) or create the httplib2.Http() object inside the method for every call of the _http() method (as shown in the code sample below) import httplib2 import urllib class apiWrapper: def __init__(self): def _http(self, url, method, dict): '''Im using this wrapper arround the http object all the time inside the class''' http = httplib2.Http() params = urllib.urlencode(dict) response, content = http.request(url,params,method)

  • The advantages and disadvantages of using ORM

    - by JHarley1
    Good Morning, I would like to discuss today the advantages and disadvantages of using ORM (such as ADO.NET). Advantages: Speeds-up Development - eliminates the need for repetitive SQL code. Reduces Development Time. Reduces Development Costs. Overcomes vendor specific SQL differences - the ORM knows how to write vendor specific SQL so you don't have to. Disadvantages: Loss in developer productivity whilst they learn to program with ORM. Developers loose understanding of what the code is actually doing - the developer is more in control using SQL. ORM has a tendency to be slow. ORM fail to compete against SQL queries for complex queries. In summary, I believe that the disadvantages of using an ORM (mainly the reduced time taken to perform repetitive tasks) is far outweighed by the disadvantages of ORM e.g. its difficulty to get to grips with. Can people point out were I am going wrong and suggest any further advantages/disadvantages. Many Thanks, J

  • Using DotNetZip Library unzip file with non ASCII characters

    - by Morten Lyhr
    I'm trying to unzip a file, using DotNetZip Library. The file contains folders and files with danish characters (æøåÆØÅ). TotalCommander, 7Zip, Windows own zip all extract the files correctly, but DotNetZip Library mangles the danish characters. Ex: File_æøåÆØÅ.txt becomes File_æ¢åÆ¥Å.txt insted of aø it contains a ¢. insted of a Ø it contains a ¥. Code: using (var zipFile = ZipFile.Read(@"File_æøåÆØÅ.zip")) { zipFile.ExtractAll(@"File_æøåÆØÅ", ExtractExistingFileAction.OverwriteSilently); } I'm using the default encoding("da-DK" culture), I have tried other encodings like UTF8 etc. How can I unzip a file containing filenames with Danish characters?

  • Using Subversion in Xcode

    - by Kevin L.
    It seems that all of the initial Google results for "using subversion with xcode" are actually just tutorials for installing and configuring svn and Xcode, as opposed to actually using the two (i.e. interacting with svn via Xcode's GUI). Is anyone aware of a good guide that teaches the tricks and pitfalls of working with svn via Xcode's GUI? Something that bridges the gap between the most excellent Version Control with Subversion book and the Xcode IDE (as in pure Xcode GUI without any terminal command use)? Edit: We all love our terminal commands, and we all love Eclipse but (and I mean this in the nicest possible way) neither is really the point of the question. I’d prefer to use svn via Xcode’s IDE instead of via terminal just as I prefer (well, for this case) to code in Xcode’s IDE instead of using vim and gcc. Apple engineers spent a good bit of time implementing that SCM menu in Xcode; someone has to have seen a usage guide somewhere.

  • Creating a spider using Scrapy, Spider generation error.

    - by Nacari
    I just downloaded Scrapy (web crawler) on Windows 32 and have just created a new project folder using the "scrapy-ctl.py startproject dmoz" command in dos. I then proceeded to created the first spider using the command: scrapy-ctl.py genspider myspider myspdier-domain.com but it did not work and returns the error: Error running: scrapy-ctl.py genspider, Cannot find project settings module in python path: scrapy_settings. I know I have the path set right (to python26/scripts), but I am having difficulty figuring out what the problem is. I am new to both scrapy and python so there is a good possibility that I have failled to do something important. Also, I have been using eclipse with the Pydev plugin to edit the code if that might cause some problems.

  • rails using jruby 1.5 - slow!!

    Hi! I'm currently using passenger with ree 1.8.7 in production for a rails 2.3.5 project using postgresql as a database. ab -n 10000 -c 100: 285.69 [#/sec] (mean) I read jruby should be the fastest solution, so I installed jruby-1.5.0.rc2 together with jdbc postgres adapter and glassfish. As the performance is really poor, I also started running my application using "jruby --server -J-Druby.jit.threshold=0 script/server -e production". Anyway, I only get ab -n 10000 -c 100: 43.88 [#/sec] (mean) Thread_safe! is activated in my rails config.

  • authlogic auto_register feature using my options

    I have auto registration working with authlogic using gaizka's version of authlogic_openid which I found on Github since pelle's original addition of the feature seemed to cause issues. http://github.com/gaizka/authlogic%5Fopenid http://stackoverflow.com/questions/1476953/using-authlogic-to-auto-create-users-bypassing-explicit-user-registeration This one works fine however when using the auto_register feature it ignores my options for authlogic such as retrieving the email from the openid provider... any ideas what I'm doing wrong? Hhere's the example: http://big-glow-mama.heroku.com/ http://github.com/holden/authlogic_openid_selector_example/tree/with-facebook/ You can see the difference if you register vs. login... #user.rb class User < ActiveRecord::Base acts_as_authentic do |c| c.validate_login_field = false # optional, but if a user registers by openid, he should at least share his email-address with the app c.validate_email_field = false # fetch email by ax c.openid_required_fields = [:email,"http://axschema.org/contact/email"] #c.required_fields = ["http://axschema.org/contact/email"] # fetch email by sreg #c.optional_fields = ["email"] end #private method to deal with emails goes here end #UserSession.rb class UserSession < Authlogic::Session::Base auto_register logout_on_timeout true end

  • using MEF with NHibernate and windsor

    - by Fran
    I have an ASP.net MVC application that is using NHibernate under the covers for data access. I'm using the Windsor container to handle injecting ISession references into each controller. This works great, but now I'm looking to expand my application with a pluggable architecture so that I can have a core product and specific add-ons. I found a great article on doing this with MEF. My question is how to make the Windsor container and MEF container, life/work together so that I can achieve this. There was an article (http://codebetter.com/blogs/glenn.block/archive/2009/10/31/should-i-use-mef-with-an-ioc-container.aspx) by Glenn Block that talked about this exact issue. Then end then said that the next article would show you how to do this, but there's no part 2. Has anyone created an application like this using asp.net mvc, mef, nhibernate, castle windsor?
