• C/C++ for Core Logic Development of a Web Application?

  - by Ramiz Uddin

  Can C/C++ be choice of keeping all your logic (business/domain) for web application? Why? I've two resources (cousins) having knowledge on C/C++ and me also good in C/C++, Python, HTML, CSS and JavaScript. We like to utilize our free time to work on our some good ideas we developed together. The ideas require knowledge of web application development. And I'm the only one who has it. Is there a way they developed the core in C/C++ and I do the rest of scripting for front-end development? Thanks.

• Git tutorial: Understanding git pull and branches (using a specific example repo)

  - by dreftymac

  Backround: Suppose I have the following Git URLs (hosted on github) http://github.com/mikl/drupal.git git://github.com/mikl/drupal.git (Git read-only) I am interested in having a local copy of this repository so I can pratice working with branches in git and see how my local working tree can change depending on which branch I am working with. Questions: To get started, I set up a local directory and do git clone git://github.com/mikl/drupal.git ... Will this clone all of the branches? Or will it only clone master? The web front-end for github gives me a "drop down" menu that allows me to switch branches ... Does changing this drop-down actually change which branch I will be grabbing when I run git clone? If I want a new copy of this repository on my local machine, but I am interested in only two branches of this repository and I want to ignore all the rest, what command do I use to ensure I clone only those two branches and nothing else (assume one of the branches is master)?

• Is it possible to implement any kind of file upload recovery / resumption in a browser?

  - by Pete

  The project is a servlet to which people can upload files via, at present, HTTP POST. This is accompanied by Web page(s) providing a front-end to trigger the upload. We have more or less complete control over the servlet, and the Web pages, but don't want to impose any restrictions on the client beyond being a reasonably modern browser with Javascript. No Java applets etc. Files may potentially be large, and a possible use case is mobile devices on less reliable networks. Some people on the project are demanding the ability to resume an upload if the network connection goes down. I don't think this is possible with plain HTTP and Javascript in a browser, but I'd love to be proved wrong. Any suggestions?

• Tap, Pan for a map & fixed headers - event conflict

  - by kaiser

  I'm currently developing a small WebApp that makes use of Google Maps (front-end uses jquery-ui-maps) jQuery Mobile with a fixed header & footer Now I encountered a conflict that appears on touch enabled devices as well as on desktop/mouse controlled "click" events: When I "tap" or "click" the map to actually "pan" it, then my header/footer toggles it's visibility. As I want to keep the toggle behaviour, I can't simply deactivate it, but showing/hiding the header/footer on every "pan" of the map is odd. After thinking some time about it, I think I got a concept that should work: Question: How I can I add a delay to the visibility toggle for the header/footer? So when I don't release the finger/mouse after XYms, the header/footer doesn't show/hide? Example: jQuery( '#map_page' ).live( "pageinit" ,function() { // Att.: pseudo code if ( $.mobile.taphold ) don't toggle fixed if ( mousedown > XYms ) don't toggle fixed } ); Thanks!

• XNA popup text dialog

  - by mazzzzz

  Hey guys, I am working on a game, and wanted to add a screen that would open when the user clicked on certain objects. The screen would be laid out to have an image on the left, a title on the top right, and text below the title. I have a few problems with this, 1) How would I create the popup box? (preferably with rounded edges) 2) How would I wrap the text (in front of the picture, but not outside the popup-box, I may even need vertical scroll bars) 3) How would I account for different screen resolutions (would they even make a difference?) Thanks for any and all help, Max

• Need a jQuery Lightbox plugin that supports $.live() and grouping

  - by Throlkim

  I'm bringing in all of my images via Ajax, and I'm looking for a quick fix for the front-end of this project. I've tried a couple of jQuery lightbox plugins, but I can't seem to get them to perform in a live function (correct me if I'm wrong in thinking I need to do this). Currently attempting to use Balupton's Lightbox Plugin (can't link because of my being a new user), and after trying all of the examples to no avail, I've attempted it with this (also not working): $('a.lightbox-gallery').live('click', function(){ $(this).lightbox(); }); Any help is much appreciated!

• VB.net Net after load event?

  - by themaninthesuitcase

  I need some way of knowing when a form has finished loading. My reasoning is I have a 2nd form that is loaded when this form loads. The code for this is called from form1.load. Form2 is currently being displayed behind form1 as I am guessing form1 calls an activate or similar at the end of the load so any Activate, BringToFront etc calls on from2 are over ridden. If you look at the code below I have tried adding frmAllocationSearch.Activate, frmAllocationSearch.BringToFront and Me.SendToBack after the call to ShowAlloactionSearchDialog() but these are all wasted as something is happening after the load event is fired to bring Me to the front. Code is: Private Sub Allocation_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ShowAlloactionSearchDialog() End Sub Private Sub ShowAlloactionSearchDialog() If frmAllocationSearch Is Nothing OrElse frmAllocationSearch.IsDisposed Then frmAllocationSearch = New AllocationSearch frmAllocationSearch.MdiParent = Me.MdiParent frmAllocationSearch.Info = Me.Info frmAllocationSearch.Top = Me.Top frmAllocationSearch.Left = Me.Left + Me.Width - frmAllocationSearch.Width frmAllocationSearch.AllocationWindow = Me frmAllocationSearch.Show() Else If frmAllocationSearch.WindowState = FormWindowState.Minimized Then frmAllocationSearch.WindowState = FormWindowState.Normal frmAllocationSearch.Activate() End If End Sub

• Should I obscure primary key values?

  - by Scott

  I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?

• Proper way to set object instance variables

  - by ensnare

  I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.

• "Disabling" an HTML table with javascript

  - by Blair Jones

  I've seen this done in a lot of sites recently, but can't seem to track one down. Essentially I want to "disable" an entire panel (that's in the form on an HTML table) when a button is clicked. By disable I mean I don't want the form elements within the table to be usable and I want the table to sort of fade out. I've been able to accomplish this by putting a "veil" over the table with an absolutely positioned div that has a white background with a low opacity (so you can see the table behind it, but can't click anything because the div is in front of it). This also adds the faded effect that I want. However, when I set the height of the veil to 100% it only goes to the size of my screen (not including the scrolling), so if a user scrolls up or down, they see the edge of the veil and that's not pretty. I'm assuming this is typically done in a different fashion. Does anyone have some suggestions as a better way to accomplish this?

• Add share button in magiczoomplus

  - by duyen hoang

  I am creating a WordPress site using Artisteer and various plugins to show off some photo galleries. I have also purchased a e-commerce WordPress theme that I have included as a subdirectory. In this theme they have a share button that I like the functionality of. I want to replicate the button in the front section of the site within the gallery pages. See the attached links to see what I am talking about. http://rrestricted.com/eshop/20mens/jay-chillin http://rrestricted.com/gallery/jay-3 The first link has the share button (loveheart icon) and the second the gallery that I want to add the button to. If you click on the images in the gallery you will see a large lightbox come up. I want to add the Share button just above the navigation buttons. This is my require from a customer. I was searched magiczoomplus.js, but I can't add it.

• Learning web development as I go

  - by Matt Luongo

  Hey everybody, I've been seriously preparing to take the entrepreneurship leap. I've got a great partner, and we're going to take on some minor funding, and do the thing. Our product is web-based- I'll deem it YAWA (Yet Another Web Application). Both my partner and I have database and web development experience, and I've had a front-end developer in mind for a while. Except, well- he just bowed out. I know a fair amount about the associated technologies (XHTML, CSS, Javascript and some JQuery) interface-side, but I've never had to deal with real-world scenarios, eg cross-browser design. Am I going to be able to survive without this guy? Is it realistic to believe that I can learn the details as I go?

• C++11 VS 2012 functor seems to choke when I have more than 5 parameters

• How to add a Web Reference to a SSL web service?

  - by Matt W

  Hi, I have a web service in a C#/3.5 project which has been running fine. This is until I set the "SSL port" in IIS to 443 and set the "IIS - Directory Security - Secure Communications - Require secure channel (SSL)" option to true. Now, the web reference cannot be updated and I cannot add a new web reference to the web service in that site. When I try to view the service in a browse using just HTTP I get the "This page must be viewed over a secure channel" and when viewed with HTTPS on the front I get "This web page not available." Could someone tell me how to get a Web Reference added using Visual Studio to this secure web service, please? Thanks, Matt.

• C++ stack memory still valid?

  - by jbu

  Hi all, If I create an object on the stack and push it into a list, then the object loses scope (outside of the for loop in the example below) will the object still exist in the list? If the list still holds the object, is that data now invalid/possibly corrupt? Please let me know, and please explain the reasoning.. Thanks, jbu class SomeObject{ public: AnotherObject x; } //And then... void someMethod() { std::list<SomeObject> my_list; for(int i = 0; i < SOME_NUMBER; i++) { SomeObject tmp; my_list.push_back(tmp); //after the for loop iteration, tmp loses scope } my_list.front(); //at this point will my_list be full of valid SomeObjects or will the SomeObjects no longer be valid, even if they still point to dirty data }

• Android Keep Activity from Dieing

  - by GuyNoir

  The main Activity I use in my Android application uses a fair amount of memory, meaning that on a less powerful phone, it is susceptible to being killed off when not at the front. Normally this is fine, but it also happens when I am still inside my application, but have a different activity at the top of the stack (such as a preference activity). Obviously it's a problem if my application is killed while the user is still running it. Is there any way to disable the OS's ability to kill off the application for low memory problems? Thanks.

• IPhone Dev: Activate the view of a tabBar button

  - by Alex N Sanchez

  Hi, I have an application that has a tabBar that handles all the views. In the first view I have a login process. When that process finishes I want to go automatically to the second tabBar view without making the user to click in its respective tabBar button. All I've got until now is to highlight the button with this: myTabBar.selectedItem = [myTabBar.items objectAtIndex:1]; But I have no idea about how to bring the second view related to that button to the front, automatically. Until now the user has to press the button when it gets lighted (selected). Any idea about how to do this? Is it possible? It would be much appreciated. Thanks.

• Cloud Agnostic Architecture?

  - by Dave

  Hi, I'm doing some architecture work on a new solution which will initially run in Windows Azure. However I'd like the solution (or at least the architecture/design) to be Cloud Agnostic (to whatever extent is realistic). Has anyone done any work on this front or seen any good white papers/blog posts? Our highlevel architecture will consist of a payload being sent to a web service (WCF for instance), this will be dumped on a queue (for arguments sake) and a worker process will grab messages off this queue and proccess them. There will be a database of customer information which we'd ideally like to keep out of the cloud however there are obvious performance considerations. Keen to hear other's thoughts. Cheers Dave

• language to create flowcharts

  - by robintw

  Hi, This seems like something which must have been answered before, but I can't find anything appropriate in the question archives. Basically, I'm looking for a little Domain Specific Language to create flowcharts. I'm terrible at graphic design and making things look nice, and I'd really like a langauge where I could write something in code and it would produce a pretty flowchart. I've come across GraphViz, but it seems more suited to creating things like Finite State Machine diagrams, rather than process flowcharts. It also doesn't have the simple DSL-style front-end that would allow me to easily work it. Any ideas? I'm sure this must have been done before... Robin

• 'Error serializing body'. Problem calling Fedex webservice through .NET 3.5

  - by Simon_Weaver

  I'm using Fedex's web services and getting an annoying error right up front before I can actually get anywhere. There was an error in serializing body of message addressValidationRequest1: 'Unable to generate a temporary class (result=1). error CS0030: Cannot convert type 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement[]' to 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement' error CS0029: Cannot implicitly convert type 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement' to 'FedEx.InterOp.AddressValidationServiceReference.ParsedElement[]' '. Please see InnerException for more details. I'm using .NET 3.5 and get a horrible named class generated for me (I'm not sure why it isn't just AddressValidationService): AddressValidationPortTypeClient addressValidationService = new ...; on this class I make my web service call: addressValidationService.addressValidation(request); This is when I get this error. The only references I can find to this error come from ancient 1.1 projects. In my case my DLL has references to System.Web and System.Web.Services which seemed to be an issue back then.

• Cannot select/edit TineMCE-generated table

  - by Rakward

  I'm currently using TinyMCE edit in my drupal-website, problem is that beneath the editor, some of the table is sticking out. If I remove the height set by javascript with firebug, it looks fine, even after resizing. So I want to remove the height with JS, I've put this function at the end of my page: $('table#edit-body_tbl').removeAttr('style'); However nothing happens. I test the function in firebug's console, it works perfectly. Basically, the problem is the JS works, but it wont do anything if I simply load it at the end of the page, even in the document.ready function. The TineMCE script is loaded before my script so I should be able to select/edit/delete elements generated by it no? Does anybody know why or how I can force the page to really load my function in the end(currently it is right in front of the -tag)? Other functions in the script work, except this thing ...

• Best Approach to process images in Django

  - by primalpop

  I've have an application with Android front end and Django as the back end. As part of the answers here, I'm confused over the approach which I should take to send images to Django Server. I've 2 options at my disposal as Piro pointed out there. 1) Sending images as Multi Part entity 2) Send image as a String after encoding it using Base 64. So I am considering the approach that would make it easy to be processed by Django. The images are small in size (<200kb) and number (<10). Any suggestions or pointers are most welcome.

• Correct usage of Voldemort as key-value pair?

  - by zengr

  Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.
