  • pdf viewer for pyqt4 application?

    - by japs
    Hi all, I'm writing a Python+Qt4 application that would ideally need to pop up a window every once in a while, to display pdf documents and allow very basic operations, namely scrolling through the different pages and printing the document. I've found the reportLab to create pdf files, but nothing about pdf viewers. Does anyone knows anything that might help. i was really hoping for the existence of something like the QWebView widget... thanks in advance to all

  • jQuery ajax() returning json object to another function on success causes error

    - by Michael Mao
    Hi all: I got stuck in this problem for an hour. I am thinking this is something relates to variable scoping ? Anyway, here is the code : function loadRoutes(from_city) { $.ajax( { url: './ajax/loadRoutes.php', async : true, cache : false, timeout : 10000, type : "POST", dataType: 'json', data : { "from_city" : from_city }, error : function(data) { console.log('error occured when trying to load routes'); }, success : function(data) { console.log('routes loaded successfully.'); $('#upperright').html(""); //reset upperright box to display nothing. return data; //this line ruins all //this section works just fine. $.each(data.feedback, function(i, route) { console.log("route no. :" + i + " to_city : " + route.to_city + " price :" + route.price); doSomethingHere(i); }); } }); } The for each section works just fine inside the success callback region. I can see Firebug console outputs the route ids with no problem at all. For decoupling purpose, I reckon it would be better to just return the data object, which in JSON format, to a variable in the caller function, like this: //ajax load function function findFromCity(continent, x, y) { console.log("clicked on " + continent + ' ' + x + ',' + y); $.ajax( { url: './ajax/findFromCity.php', async : true, cache : false, timeout : 10000, type : "POST", dataType : 'json', data : { "continent" : continent, "x" : x, "y" : y }, error : function(data) { console.log('error occured when trying to find the from city'); }, success : function(data) { var cityname = data.from_city; //only query database if cityname was found if(cityname != 'undefined' && cityname != 'nowhere') { console.log('from city found : ' + cityname); data = loadRoutes(cityname); console.log(data); } } }); } Then all of a sudden, everything stops working! Firebug console reports data object as "undefined"... hasn't that being assigned by the returning object from the method loadRoutes(cityname)? Sorry my overall knowledge on javascript is quite limited, so now I am just like a "copycat" to work on my code in an amateur way.

  • WPF Visual Studio Package gives error: Could not find endpoint element with name 'WCFname' and contr

    - by Andrei
    Hi everybody. This error has been covered before in other questions, however not for a Visual Studio package. Could not find endpoint element with name 'WCFname' and contract 'WCFcontract' in the ServiceModel client configuration section. I have a VS package project that needs to connect to a WCF service that provides some functionality. I add a reference to the WCF service and Visual Studio automatically creates the content for the configuration file. config file: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.serviceModel> <bindings> <wsHttpBinding> <binding name="WSHttpBinding_IWCFSearchService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Message"> <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" /> <message clientCredentialType="Windows" negotiateServiceCredential="true" algorithmSuite="Default" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="http://localhost:8732/Design_Time_Addresses/WCFSearchServiceLibrary/Service1/" binding="wsHttpBinding" bindingConfiguration="WSHttpBinding_IWCFSearchService" contract="WCFSearchServiceReference.IWCFSearchService" name="WSHttpBinding_IWCFSearchService"> <identity> <dns value="localhost" /> </identity> </endpoint> </client> </system.serviceModel> </configuration> However, when I run the application (in VS experimental mode) it doesn't seem to take the provided configuration file (app.config). Everytime it just throws this error: Could not find endpoint element with name 'WSHttpBinding_IWCFSearchService' and contract 'WCFSearchServiceReference.IWCFSearchService' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this name could be found in the client element. My guess is that it's taking the configuration file for Visual Studio (since it is running VS experimental mode). So yeah...why isn't it recognizing the app.config file and how could I make the application to recognize it? Any help would be very welcomed as I have already tried to fix this for some time. Thanks.

  • c++ FFT Beat detection library?

    - by mokaschitta
    Hi, I am currently looking around for a good allround beat detection library / source code in C++ since I found it really hard to achieve satisfying results with the beat detection code I wrote myself using this tutorial: http://www.gamedev.net/reference/programming/features/beatdetection/ It's especially really hard if you want to make it work with any kind of music so I was wondering if there is something usable out there allready? Thanks!

  • Jini : single server with multiple clients

    - by user200340
    Hi all, I have a question about how to make multiple clients can access a single file located on server side and keep the file consistent. I have a simple PhoneBook server-client Jini program running at the moment, and server only provides some getter functions to clients, such as getName(String number), getNumber(String name) from a PhoneBook class(serializable), phonebook data are stored in a text file (phonebook.txt) at the moment. I have tried to implement some functions allowing to write a new records into the phonebook.txt file. If the writing record (name) is existing, an integer number will be added into the writing record. for example the existing phonebook.txt is .... John 01-01010101 .... if the writing record is "John 01-12345678",then "John_1 01-12345678" will be writen into phonebook.txt However, if i start with two clients A and B (on the same machine using localhost), and A tries to write "John 01-11111111", B tries to write "John 01-22222222". The early record will be overwritten later record. So, there must be something i did complete wrong. My client and server code are just like Jini HelloWorld example. My server side code is . 1. LookupDiscovery with parameter new String[]{""}; 2. DiscoveryListener for LookupDiscovery 3. registrations are saved into a HashTable 4. for every discovered lookup service, i use registrar to register the ServiceItem, ServiceItem contains a null attributeSets, a null serviceId, and a service. The client code has: 1. LookupDiscovery with parameter new String[]{""}; 2. DiscoveryListener for LookupDiscovery 3. a ServiceTemplate with null attributeSets, a null serviceId and a type, the type is the interface class. 4. for each found ServiceRegistrar, if it can find the looking for ServiceTemplate, the returned Object is cast into the type of the interface class. I have tried to google more details, and i found JavaSpace could be the one i missed. But i am still not sure about it (i only start Jini for a very short time). So any help would be greatly appreciated.

    - by Funky81
    Is there anyone already implement memcached for production use in Windows environment? Because many blogs that I've read, it's not recommended to run memcached in Windows especially for production use, for example running memcached on windows. And one more thing, which memcached client that is good to use with c# and .net 3.5 ? I've found many alternate such as Memcached Providers @ Codeplex, Beitmemcached, and memcached provider @ Sourceforge

  • Why is the concept of Marshalling called as such?

    - by chickeninabiscuit
    I've always thought that the concept of Marshalling had a bit of a funny name. My mental conception of the process would always involve an ol' wildwest gunslinging marshall who would coerce objects into serialized form at gunpoint. I just found out the real reason Marshalling is called what it's called and chuckled. Do you know the real reason, or perhaps you too are familiar with my gunslinger?

How do I get the MarkItDown Textarea on a postback and get the preview to work as well?

  • How to Minify .net AXD Resources

    - by Ilya Biryukov
    Hey I am working on a big .NET project. I am currently creating an automated minifier for JS and CSS files using YUI compressor. After doing some research, I found that the heaviest files in the project are actually .NET resources (Like MS ajax file). They are very big and unminified. I am wondering, is there any way to minify them? Thanks

  • Fact or fiction: Webkit’s rendering performance is much lower when used in Qt

    - by Jen
    Using Qt’s Webkit implementation renders much slower than directly implementing the Webkit engine -- is this true or just a myth? From my own experience, I found the load time of a complex page about twice as long in Qt’s “Fancy Browser” example as it does in Google Chrome (which also incorporates a port of Webkit), but I hardly think that is a fair comparison. Any insights on this?

  • jQueryMobile: how to work with slider events?

    - by balexandre
    I'm testing the slider events in jQueryMobile and I must been missing something. page code is: <div data-role="fieldcontain"> <label for="slider">Input slider:</label> <input type="range" name="slider" id="slider" value="0" min="0" max="100" /> </div> and if I do: $("#slider").data("events"); I get blur, focus, keyup, remove What I want to do is to get the value once user release the slider handle and having a hook to the keyup event as $("#slider").bind("keyup", function() { alert('here'); } ); does absolutely nothing :( I must say that I wrongly assumed that jQueryMobile used jQueryUI controls as it was my first thought, but now working deep in the events I can see this is not the case, only in terms of CSS Design. What can I do? jQuery Mobile Slider source code can be found on Git if it helps anyone as well a test page can be found at JSBin As I understand, the #slider is the textbox with the value, so I would need to hook into the slider handle as the generated code for this slider is: <div data-role="fieldcontain" class="ui-field-contain ui-body ui-br"> <label for="slider" class="ui-input-text ui-slider" id="slider-label">Input slider:</label> <input data-type="range" max="100" min="0" value="0" id="slider" name="slider" class="ui-input-text ui-body-null ui-corner-all ui-shadow-inset ui-body-c ui-slider-input" /> <div role="application" class="ui-slider ui-btn-down-c ui-btn-corner-all"> <a class="ui-slider-handle ui-btn ui-btn-corner-all ui-shadow ui-btn-up-c" href="#" data-theme="c" role="slider" aria-valuemin="0" aria-valuemax="100" aria-valuenow="54" aria-valuetext="54" title="54" aria-labelledby="slider-label" style="left: 54%;"> <span class="ui-btn-inner ui-btn-corner-all"> <span class="ui-btn-text"></span> </span> </a> </div> </div> and checking the events in the handler anchor I get only the click event $("#slider").next().find("a").data("events");

  • Agile Development - Developer Qualification required, and Disadvantages of

    - by Everyone
    We have been using Agile on a project for 3 years now. Albeit I was new to scrum, it came to me easily enough. However we found it quite difficult to break any freshers into the scrumming process. One reason may have been that estimation for the future requires domain and technology depth that freshers lack. What, if any is the necessary qualification for a developer be part of an Agile team? What, in your experience, are drawbacks to Agile?
