• check external website registration

  - by Arsenal

  Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

• Uploadify and Image Compression

  - by Ilya Biryukov

  Hi, I am using Uploadify on one of my client's web sites to allow them to upload a large amount of pictures at once to their photo gallery. I am seeing issues lately. They seem to upload large photographs (3 MB and above). I am wondering, is it possible to compress (reduce their size) on the client side, instead of doing it on the server (just like facebook does it). I know I could easily do it on the server, but I am working on another project right now, where I am expecting a large flow of photo uploads. It would require significant amount of CPU time to process them all. So I thought, I'd ask about the client side processing. Thanks.

• How to securely serve S3 files to blog

  - by Hugo Palma

  I'm starting a blog and i'm in the process of choosing where should i host it. For now i want a free solution like Blogger or Wordpress.com. The problem i'm facing is that i want to use files i have in a S3 bucket in my blog but none of the blog solutions i found supports any kind of server code, which means that in order to use S3 query string authentication i would have to put vulnerable information in the client. For obvious reasons i don't want to do that. So, i'm looking for ideas on how i can safely include content from S3 in a free blog host.

• What is the chance a CouchDB document update handler will get a revision conflict?

  - by jhs

  How likely is a revision conflict when using an update handler? Should I concern myself with conflict-handling code when writing a robust update function? As described in Document Update Handlers, CouchDB 0.10 and later allows on-demand server-side document modification. Update handlers can process non-JSON formats; but the other major features are these: An HTTP front-end to arbitrarily complex document modification code Similar code needn't be written for all possible clients—a DRY architecture Execution is faster and less likely to hit a revision conflict I am unclear about the third point. Executing locally, the update handler will run much faster and with lower latency. But in situations with high contention, that does not guarantee a successful update. Or does the update handler guarantee a successful update?

• MS Access antiquated? Anything new in 2011?

  - by Heidi

  Our company has a database of 17,000 entries. We have used MS Access for over 10 years for our various mailings. Is there something new and better out there? I'm not a techie, so keep in mind when answering. Our problems with Access are: -no record of what was deleted, -will not turn up a name in a search if cap's or punctuation is not entered exactly, -is complicated for us to understand the de-duping process. - We'd like a more nimble program that we can access from more than one dedicated computer.

• Dynamic CSS class names in GWT

  - by Anupam Jain

  I am in the process of porting a simple CSS grid system to GWT. My CSS file currently has classes like .size1, .size2 etc., and I have a CSS resource that looks like - class MyResource extends CSSResource { @ClassName("size1") String size1(); @ClassName("size2") String size2(); // And so on } However what I really want, is to have a single function like the following - String size(int size); which will generate the appropriate class when passed the size as an integer at runtime. This is needed as I perform some calculations to determine the actual space available/needed for a widget in javascript and then attach the appropriate class name. Is this something that is even possible with GWT?

• Watir changes highline's "ask" method

  - by grundic

  Hello! I've encoutered some strange functionality, when using Watir and Highline together. Here is simple example: require 'highline/import' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp require 'watir' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp Here is an output: Company? |MySuperCompany| MySuperCompany [Company? ] => Company? Maybe it's a bug? I've also found in documentation for highline, that If @question is set before ask() is called, parameters are ignored and that object (must be a HighLine::Question) is used to drive the process instead. Sorry, I'm not a ruby guru :-(

• POS Desktop Application using DB or Localfiles ? using WPF

  - by Panindra

  I am planning to build a POS Application for my shop. I have enough knowledge to build the application using DB and also using local files( system.IO - binary files ) to store and access the data for my application. But , i have no deployment experience and confused in choosing data storing option. Database using MDF may be good option ( may ease plenty of coding ) but i don't want to have SQL server on my desktop. as i am using WPF for building , my concern is that my application may get slow due to server response and design rendering of WPF. Then i tried to use only local data (binary files) to store the data and retrive using class and objects. but this coding is taking lot of time , so in the middle of the process i struck in the dilemma of going back to Database . Please help , for performance wise whic one is better . and in Practical World ,in professional applications which one is widely using .. please give suggestions ..

• iOS and Infrared

  - by Mustafa

  Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)? Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how? What are the limitations and requirements? What kind of additional hardware is required? If it's available in the market? Which protocols should i know about? Which iOS libraries can help me in the process. Can anyone point me in the right direction. Thanks.

• Why are some VB6 DLLs loaded as mapped files?

  - by Mark Bertenshaw

  Hi - A colleague of mine, whilst trying to figure out the memory useage of our VB6 / C# 2.0 application noticed that a minority of VB6 DLLs have two entries in the SysInternals Process Explorer application. All DLLs have an entry for Mapping = Image, and a specified base address. However, a few also have an entry for Mapping = Data, with a base address of zero, and a much smaller memory useage. I seem to remember something about using mapped memory files to share memory between processes, but we are definitely not doing something as interesting as this. All communication between EXEs is done via COM, and as far as I know, nobody has written a shared memory component. This is not desperate, but I would be very interested in any suggestions as to why some DLLs are loaded as mapped file Thanks, Mark Bertenshaw

• What Database to distribute as part of a C# app backend

  - by jez

  I am planning on writing and commercialising a C# app which will store data in an underlying database I use MySQL on my environment for my own development and this is what I would have used to write the application for myself (no need to use FK - MyISAM engine would be fine). I am concerned about how easy it will be to distribute the app together with the database engine. Would using MySQL allow me for easy packaging of the app for a "one-click" install on the client side? (ie I do not want them to have to install MySQL by themselves) and also is it feasible from a licensing point of view? Are there other Database systems which would make the process more straight-forward

• Any way to animate new elements in a GridView being added?

  - by Ben L.

  My app polls a server every 15 seconds to see if there are any new items to display, then downloads the new items and disposes of the old items so that there are always exactly 100 items in the GridView. Unfortunately, this process can be confusing to the user if they see a page of images change without knowing where the items went. My idea is that there could be some kind of animation (such as the new items being inserted at the top and pushing the older ones down the list) to show what action is happening. Unfortunately, I have no clue how to make this animation happen. Is my idea even possible? How would I accomplish this?

• When using Microsoft Test Manager 2010 with SfTS, how do QA engineers know what tests they have to run?

  - by MADCookie

  We are moving our projects to TFS 2010 using the SfTS v3 (Scrum for Team System) template. We need to understand how Microsoft Test Manager is supposed to be used in this Scrum process. Specific scenario & question: The QA manager uses Test Manager to create Acceptance Test Work Items (WIs). These new WIs are created and "assigned to" him. The manager doesn't run all the tests, instead he wants to give that responsibility to his staff. How is a QA engineer supposed to know that he has tests to run? Everything says it is assigned to the manager.

• Running PHP 5.1 and 5.2 on debian squeeze

  - by Keil

  I know that Debian Squeeze won't let me compile a PHP version (prior to 5.3.0). But I need them for migrating some tools: Joomla (1.0.10) and SugarCRM (4.2.1b). Actually, Joomla 1.0.10 can run on PHP 5.2, and SugarCRM on PHP 5.1. But both will complain running under PHP 5.3. So, I want to execute their upgrade process under their working PHP version, so after the upgrade, they may not complain anymore under PHP 5.3. FYI, Apache is not the only option I have as WebServer. Maybe I am wrong thinking this way, if so, please explain the differents steps I need. So the question is: How can I have these PHP versions running on Squeeze?

• Developing browser plug-ins?

  - by JavaMan

  I have a project that I'd like to try that involves developing an internet browser plug-in. I have knowledge in Java and DHTML, but nothing in the world of browser plug-in development. I thought I would just ask here then what is the most efficient way to develop a browser plug-in? If possible, I'd like to streamline the process so that getting the plug-in to work in different browsers involves as little work as possible. Can this be done? I'm not asking for a tutorial like the trolls do, just a few pointers that's all. I don't waste mine or anyone else's time.

• xcodeproj merge fails when adding new group

  - by user1473113

  I'm currently using Xcode with Git, and I'm experiencing some troubles during the merge process of my xcodeproj. Developer1 create a new group in Xcode file arborescence the commit and push. Developer2 on an other computer do the same with an other group name, commit and pull(with merge). The xcodeproj of Developer 2 become unreadable with Xcode. But when I create a new file or just drag and drop files from finder to repository, the merge succeed. Did someone has experienced that kind of trouble? I'm using in .gitattributes: *.pbxproj -crlf -diff merge=union # Better to treat them as binary files. *.pbxuser -crlf -diff -merge *.xib -crlf -diff -merge and in my .gitignore # Mac OS X *.DS_Store *~ # Xcode *.mode1v3 *.mode2v3 *.perspectivev3 *.xcuserstate project.xcworkspace/ xcuserdata/ *.xcodeproj/* !*.xcodeproj/project.pbxproj !*.xcodeproj/*.pbxuser # Generated files *.o *.pyc *.hi #Python modules MANIFEST dist/ build/ # Backup files *~.nib \#*# .#*

• Mock a void method which change the input value

  - by Kar

  Hi, How could I mock a void method with parameters and change the value parameters? My void method looks like this: public interface IFoo { void GetValue(int x, object y) // takes x and do something then access another class to get the value of y } I prepared a delegate class: private delegate void GetValueDelegate(int x, object y); private void GetValue(int x, object y) { // process x // prepare a new object obj if (y == null) y = new Object(); if (//some checks) y = obj; } I wrote something like this: Expect.Call(delegate {x.GetValue(5, null);}).Do (new GetValueDelegate(GetValue)).IgnoreArguments().Repeat.Any(); But seems like it's not working. Any clue on what could be wrong?

• Buy or build tool for Data Reporting ?

  - by Manoj

  We have been asked to provide a data reporting solution. The followng are the requirements: i. The client has a lot of data which is generated everyday as an outcome of the tests they run. These tests are run at several sites and they get automatically backed up into a central server. ii. They already have perl scripts which post process them and generates excel based reports. iii. They need a web based interface for comparing those reports and they need to mark and track issues which might be present in those data. I am confused if we should build our own tool for this or we should go for already exiting tool(any suggestions?). Can you please provide supportive arguments for the decision that you would suggest?

• Sending JSON(jQuery) to PHP and decoding it

  - by dscher

  I can't for the life of me figure out what I'm doing wrong. It seems like it should be simple because I can't find anyone else with this issue but I can't figure out to send basic data via javascript(jQuery) to PHP and decode it. For the sake of simplicity, this is what I have: JAVASCRIPT var json_data = { "name" : "john doe" }; $.ajax({ type: "POST", url: "../bin/process.php", dataType: "json", data: json_data }); and my PHP FILE $arr = json_decode("json_data", true); $fp = fopen('data.txt', "w"); fwrite($fp, $arr['name']); fclose($fp); The file I'm writing ends up with nothing in it. If I do an: fwrite($fp, 'test'); I get a file with the word test in it but no matter what I do I don't get the json data I sent. Can someone please share a thorough example of A to Z. Thanks for any help.

• ASP.NET Forms automation/serialization/binding

  - by creo

  I need to implement many forms in ASP.NET application (for IRS mostly). There are will be a lot of standard controls for each form (textboxes, dropdowns, checkboxes, radio). And business entity assigned to each. What's the best solution to automate this process? I need to: Have layout stored in DB (in XML). Layout must support several columns, tabbed interface Automatically bind business object values to the form Automatically read form values and write to business object Must support automatic validation Some basic workflows support would be good I used to work with TFS and saw how they implemented WorkItem templates (.wit files). In general this is all I need. But what framework did they build it on? How can I utilize this solution? I know about Dynamic Data only: http://www.asp.net/dynamicdata
