• The next step & technology towards web services.

  - by webzide

  Hi, My name is Dennis and I am pretty ambitious of creating the next big thing for the web. I have ideas but now I gotta get to work to learn the tools. I am learning Javascript. I don't know if next step for me to take is PHP or some suggests RUBY on Rails. What are the pros and cons. With your experience, I wish you could hint me to the right direction. Thanks. I don't mind working hard. My goal is to create a comprehensive and secure web service platform as well as a fast and user friendly UI.

• Drupal: Two-way communication between unregistered customer and admin

  - by Bryan Folds

  I need to setup a system where customers can choose to Request a Quote for a specific holiday package, where they will enter their personal details as well as their holiday requirements (number of rooms, etc.) and will then allow them to view a page which will have a threaded conversation between them and the admin (so the admin can reply to their quote request on the website). The problem is that most customers won't be registered when they want to request a quote, so I was thinking that the Request a Quote page could silently register the customer as a user (using their personal details) on the same page where it asks for their holiday requirements. The other option I can think of would be to not register them and just email them a unique URL where they can view their quote request and reply to the admin. Could you point me in the right direction on how to do either of those?

• How would I go about building a calendar UI control for the iPhone/iPad?

  - by BeachRunnerJoe

  Hello. There are a few different 3rd party code frameworks that include calendar controls, but most of them have a lot of functionality I don't need, plus most of them lack sufficient documentation on how to use them and I'm not a proficient enough iPhone developer figure it out using just the code. So I'm going to attempt to build my own and I was hoping you could provide me with some high-level direction to get started. At a high level, how could I build a simple, calendar control that doesn't do much more than display a calendar (month view, with the current date highlighted) and allows the user to selected a date? Something that looks like the calendar in the upper right corner of this image... Thanks so much in advance for your help!

• Should I be building GUI applications on Windows using Perl & Tk?

  - by CheeseConQueso

  I have a bunch of related Perl scripts that I would like to put together in one convenient place. So I was thinking of building a GUI and incorporating the scripts. I'm using Strawberry Perl on Windows XP and have just installed Tk from cpan about fifteen minutes ago. Before I go for it, I want some sound advice either for or against it. My other option is to translate the Perl scripts into VB and use Visual Studio 2008, but that might be too much hassle for an outcome that might end up all the same had I just stuck with Perl & Tk. I haven't looked yet, but maybe there is a module for Visual Studio that would allow me to invoke Perl scripts? The main requirements are: It must be able to communicate with MySQL It must be able to fetch & parse XML files from the internet It must be transportable, scalable, and sustainable What direction would you take?

• Reading what is in the vsdiagnostics blob in Azure (1.7)

  - by tomasmcguinness

  I've enabled Diagnostics in one of my Worker roles and published it to Azure. There was a new blob container created called "vsdiagnostics" and contained within in are two binary files. I'm assuming that these files contain the output of my Trace statements, but I'm unable to open these files as I have no idea what format they are in. I've not found anything on www.windowsazure.com about it and most of the tools they recommend are very outdated. I have installed Cerebrata's Azure Diagnostics Manager, but that isn't able to load the Trace Logs. If anyone could point me in the right direction I'd be grateful!

• iPad to iPhone?

  - by Brodie4598

  Hello - I have written a tab based iPad application which has done well. I never intended for it to be an iPhone application because the content it displays really doesnt lend itself to such a small screen. However, I have been getting a lot of requestes for the application to be compatible with iPhones as well. Can someone point me in the direction of some documentation that may help me figure out how to convert my app. I presume it's not so simple as having aanother set of XIB files for iPhone and just have it display them if the app is running on a phone...

• SaaS practical basics and projects

  - by Medardas

  So i need some directions. I want to understand Cloud Software as a Service(SaaS) practical initialization. The thing is I want to create a simple cloud service which would let me run programs on this cloud from remote machine. As I understand, I need some kind of specific backbone project to start this system, similar like OpenStack or Apache Cloud for Infostructure as a Service. Of course it may be that I understand it completely wrong and even if there is such project, it is not open source, free. I could also comprehend SaaS building on IaaS, but the thing is, I can't find any practical information at all. Could Somebody indulge me if there is any kind of free licence SaaS project or recommend a related articles or explain everything in a nut case with atleast vague direction.

• How to test silverlight behaviors using Rhino Mocks?

  - by Derek

  I have slightly adapted the custom behavior code that can be found here: http://www.reflectionit.nl/blog/default.aspx?guid=d81a8cf8-0345-48ee-bbde-84c2e3f21a25 that controls a MediaElement. I need to know how to go about testing this with Rhino Mocks e.g. how to instantiate a new ControlMediaElementAction in test code and then call the Invoke method etc. Doing something simple like this in test code: mMediaElementControlBehaviour = new ControlMediaElementAction (); gives me an exception "The type initializer for 'System.Windows.DependencyObject' throw an exception. Thinking it was the instantiation of the MediaElement, I tried this two lines of code: MediaElement mediaElementStub = MockRepository.GenerateStub(); this.Container.RegisterInstance(mediaElementStub); This gave the exception 'Can't create mocks of sealed classes' If someone can point me in the right direction, it would be apreciated. Silverlight 4, Rhino Mocks 3.5 Silverlight v2.0.50727 Thanks,

• How to setup Xcode 3.1.4 with Perforce ?

  - by Azeworai

  Hi everyone, I've been trying to setup Xcode with Perforce for about 7 hours now and managed to get the Perforce Repository Authenticated within Xcode. The problem I have is, within the repositories window, I don't see any directories for me to check out. I can see the p4root login and client are ok with the tick on the repository log. When I try to Import an xcode project directory within the Perforce root directory- the import fails with '/Users/jackson/p4root/alpha/MessageTapper' is not under the Perforce root. I have p4d running on the local machine, and have created a user and workspace. The workspace has the directories in view. I'm hoping for someone to give me some direction or maybe point me to a good reference to how to set perforce up with xcode. Thanks!

• PHP auto refresh page without losing user input

  - by Tony

  I'm working on a PHP collaboration software project. I have a page that shows the latest updates from other users who are adding content to the database, but also has a form input to allow the user to enter text. I am currently using this code to refresh the page automatically every 30 seconds: header('Refresh: 30'); The problem is that the header code refreshes the entire page, and not just what is pulled from the database. Is there any PHP code that will just pull any new data from the database without refreshing the entire page? If someone could point me in the right direction I'd appreciate it.

• Pull image of rendered HTML from a specific browser

  - by Geo Ego

  I am working on an app that will be able to pull an image of rendered HTML from a specific browser. I would like the user to be able to select a specific browser to render an HTML file in, and capture the rendered output in an image file. I am starting with IE8, and I'm not sure where to begin to get the actual rendered output. I can easily open the file in that browser with Process.Start(), but I don't know how to return the rendered output. I have looked a little bit at sinking events, but I don't understand how that works or if that's the right way to go. I would just like some direction, and perhaps some resources to send me on the right path.

• What is the correct method to load an XML file and re-write it as a CSV?

  - by codesmack

  I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named <car> and within the car element I need to process the <mileage> element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C#

• Can I programatically determine if a PNG is animated?

  - by alex

  I have PNG (as well as JPEG) images uploaded to my site. They should be static (i.e. one frame). There is such thing as APNG. (it will be animated in Firefox). According to the Wikipedia article... APNG hides the subsequent frames in PNG ancillary chunks in such a way that APNG-unaware applications would ignore them, but there are otherwise no changes to the format to allow software to distinguish between animated and non-animated images. Does this mean it is impossible to determine if a PNG is animated with code? If it is possible, can you please point me in the right direction PHP wise (GD, ImageMagick)?

• Calculating the union of 2 longitudal intervals (that may wrap around 180 degrees)

  - by timpatt

  The story: I have a LatLongBounds class that represents an area on the surface of the earth by a latitudinal interval (bounded by north & south - not important to this question) and a longitudinal interval (bounded by east and west; both normalized to a range [-180, 180] - negative being a westerly direction). In order to be able to represent an area that straddles the 180 degree meridian the value of west may be set to be greater than east (eg. the range west = 170, east = -170 will straddle said meridian). In effect the longitudinal interval may wrap around at 180 degrees (or equivalently -180 degrees). My Question: Does anyone have any suggestions as to how I can calculate the union of two longitudinal intervals that may wrap around at 180 degrees. Thanks.

• LAMP Stack with APC installed - WordPress Site - Is WP opcode being cached with APC?

  - by Christopher Altman

  I have a LAMP stack with APC installed. I have a WordPress site on this server. Is WP taking advantage of the opcode caching? I have done no WP configurations. My understanding is that simply having APC installed means that all PHP code is being cached. If that is untrue, please point me to the direction where I can configure WP to take advantage of APC. Note: I thought about this as a ServerFault question, but since the solution to is code related I posted on Stackoverflow.

• Screen Scraping

  - by Sambo

  Hi I'm trying to implement a screen scraping scenario on my website and have the following set so far. What I'm ultimately trying to do is replace all links in the $results variable that have "ResultsDetails.aspx?" to "results-scrape-details/" then output again. Can anyone point me in the right direction? <?php $url = "http://mysite:90/Testing/label/stuff/ResultsIndex.aspx"; $raw = file_get_contents($url); $newlines = array("\t","\n","\r","\x20\x20","\0","\x0B"); $content = str_replace($newlines, "", html_entity_decode($raw)); $start = strpos($content,"<div id='pageBack'"); $end = strpos($content,'</body>',$start) + 6; $results = substr($content,$start,$end-$start); $pattern = 'ResultsDetails.aspx?'; $replacement = 'results-scrape-details/'; preg_replace($pattern, $replacement, $results); echo $results;

• Posting an image and textual based data to a wcf service

  - by James Hay

  I have a requirement to write a web service that allows me to post an image to a server along with some additional information about that image. I'm completely new to developing web services (normally client side dev) so I'm a little stumped as to what I need to look into and try. How do you post binary data and plain text into a servic? What RequestFormat should I use? It looks like my options are xml or json. Can I use either of these? Bit of a waffly question but I just need some direction rather than a solution as I can't seem to find much online.

• Keeping iPhone application in sync with GWT application.

  - by Reflog

  Hi, I'm working on an iPhone application that should work in offline and online modes. In it's online mode it's supposed to feed all the information the user enters to a webservice backed by GWT/GAE. In it's offline mode it's supposed to store the information locally, and when connection is available sync it up to the web service. Currently my plan is as follows: Provide a connection between an app and a webservice using Protobuffers for efficient over-the-wire communication Work with local DB using Core Data Poll the network status, and when available sync the database and keep some sort of local-db-to-remote-db key synchronization. The question is - am I in the right direction? Are the standard patterns for implementing this? Maybe someone can point me to an open-source application that works in a similar fashion? I am really new to iPhone coding, and would be very glad to hear any suggestions. Thanks

• Why does A* path finding sometimes go in straight lines and sometimes diagonals? (Java)

  - by Relequestual

  I'm in the process of developing a simple 2d grid based sim game, and have fully functional path finding. I used the answer found in my previous question as my basis for implementing A* path finding. (http://stackoverflow.com/questions/735523/pathfinding-2d-java-game). To show you really what I'm asking, I need to show you this video screen capture that I made. I was just testing to see how the person would move to a location and back again, and this was the result... http://www.screenjelly.com/watch/Bd7d7pObyFo Different choice of path depending on the direction, an unexpected result. Any ideas?

• What is the safest way to pass strings around in C?

  - by chucknelson

  I have a program in C using Solaris with VERY ancient compatibility it seems. Many examples, even here on SO, don't work, as well as lots of code I've written on Mac OS X. So when using very strict C, what is the safest way to pass strings? I'm currently using char pointers all over the place, due to what I thought was simplicity. So I have functions that return char*, I'm passing char* to them, etc. I'm already seeing strange behavior, like a char* I passed having its value right when I enter a function, and then the value being mysteriously gone OR corrupted/overwritten after something simple like one printf() or an malloc to some other pointer. I was thinking maybe declaring a local char[] inside each function, using strcpy() immediately, and then eventually returning a pointer where char *returnval = strdup(localchar[]); This seems...sloppy. Can anyone point me in the right direction on a simple requirement?

• How to get surrounding method in Java source file for a given line number

  - by roesslerj

  I have a line number of a Java source file and want to get the sourounding method for that line number programatically. I looked into ANTLR which didn't help me much. Janino (http://www.janino.net) seems promising, I would scan and parse (and if necessary compile) the code. Then I could use JDI and ReferenceType.locationsOfLine(int lineNumber) Still I don't know how to use JDI for doing this and didn't find a tutorial that goes anywhere in this direction. Maybe there is some other way that I am completely missing.

• PayPal IPN & ASP.NET MVC

  - by Wayne

  Hello - I have a strange problem that somebody can hopefully help me with. For a while now I have been using PayPal's IPN service for our website. In order to test it I have a port opened up on our firewall pointing to my machine. This has been working great with no problems at all. I recently upgraded to the RTM release of ASP.NET MVC and now things are not working. I can navigate to my IPN handler from the outside world so I know it's not my connection or a firewall issue. It simply refuses to recieve any PayPal IPN messages. I am puzzled why the page can be accessed yet the PayPal IPN server wont connect to it. I realize there could be a 1000 different reasons for this, but I am hoping somebody out there can point me in the right direction!

• Randomly generate sound from onClick and onShake events?

  - by Aaron

  I've literally looked everywhere on the net and found very little clarification on how to do this. Pretty much, I have 8 sound files laid out in an array.xml file and I need to play a randomly chosen file ONCE per or onClick or onShake. First off, what technique should I use to achieve this? ARRAY-RANDOM- STRING-PLAY? RANDOM INT-PLAY? RANDOM INT-STRING-PLAY? Any kind of direction will help greatly cause I'm almost 3 weeks worth of research into this. *NOTE: MediaPlayer mp = MediaPlayer.create(JelloMan.this, R.raw.sound) ...is what I'm stuck on being you can't replace the "R.raw" part with a string...
