• host MVC app inside a website

  - by Nishant

  I have a website (not a web application- in visual studio you get two options-create a website/project) running on IIS 6.0. Now I want to develop few features in MVC architecture. So I created one MVC application in visual studio and everything is working fine on localhost as a separate application. Now I want to host this MVC app also inside the website I have already deployed. I created a virtual directory(MVCDir) inside the default website in IIS 6.0. The global.asax file which was in root folder I added the routing function- Shared Sub RegisterRoutes(ByVal routes As RouteCollection) routes.Ignore("{resource}.axd/{*pathInfo}") routes.Ignore("{resource}.aspx/{*pathInfo}") routes.MapPageRoute("Default4", "{controller}/{action}/{id}", "~/MVCDir", False, New RouteValueDictionary(New With {.controller = "Home", .action = "Index", .id = Mvc.UrlParameter.Optional})) End Sub * NOTE- If I write routes.ignoreRoute instead of routes,ignore it says- IgnoreRoute is not a member of System.Web.RoutingCollection* I called this routing function inside application_start function now when I run domain.com/home/index How to solve this problem? it says resource not found

• Xhtml instead of Php?

  - by ihaveitnow

  I want to develop a site that will allow be to publish information to users, and give them and opportunity to subscribe to a mailing list so they can be updated each time I make a change to the site. *Add new information, etc. I also would like for the users to be able to add comments about reviews posted, and give me suggestions...Things that will encourage user interaction I understand that this is possible with php... But I do not know php, and to learn and test it I apparently need a domain to begin with...etc. Is it possible that I use Xhtml/Html to get the same results? -- I know I can use the <a href="mailto:[email protected]"; subject="Email from Site user">Mail</a> but that would also leave my email open to spam...Any suggestions? And I do apologize if this question has been posted before, I did some research and found no such thing. All helpful responses are appreciated.

• Best architecture for accessing secondary database

  - by fearofawhackplanet

  I'm currently developing an app which will use a Linq to SQL (or possibly EF) data access layer. We already have a database which holds all our Contacts information, but there is currently no API around this. I need to interact with this DB from the new app to retrieve contact details. I can think of two ways I could do this - 1) Develop a suite of web services against the contacts database 2) Write a Linq to SQL (or EF) DAL and API against the contacts database I will probably be developing several further apps in the future which will also need access to the Contacts data. Which would generally be the prefered method? What are the points I need to consider? Am I even asking a sensible question, or am I missing something obvious?

• How to provide Input to Dialogs designed by Qt Designer

  - by GG

  Hello, I am a Qt beginner and working with Qt Designer to develop some small UI elements. I read http://doc.trolltech.com/4.5/designer-using-a-ui-file.html to use these GUI elements in my code and using multiple inheritance approach. I am introducing bookmark feature which somewhat look like http://img293.imageshack.us/img293/3041/screenshotyb.png. Now the problem I am facing is How can I show all existing bookmark folders in the drop down(say folders are in a QVector). So my main problem is how can I pass some inputs to the UI element. I think I'm clear, please let me know if further explanation is required. Sorry for adding links directly, rich formatting in my browser is not working. Thanks in advance,

• Framework/App for custom maps(not general google maps)

  - by Franz Xaver

  Hi! I've started to develop in Android 2 weeks ago and until now, I like it! Currently I am working on a project where I have to display an individual map (not a google maps view, I'd like to display the map of a building's interior) with which the user can interact(mark positions, etc.). Is there a framework or an existing app that I could use? Of course I searched the internet but could not find anything. Perhaps it is in some way possible to use the google maps API? I hope you can help me, thanks in advance!

• Active X Development: VC++ or VB or Other technologies

  - by Gopalakrishnan Subramani

  We are in the process of creating active-x controls used within our application. Since Microsoft stopped supporting classic Visual Basic, is it wise to use Visual Basic to develop the Active X control or the latest VC++/ATL/MFC libraries provide more feature where we can create controls faster by leaving Visual Basic flexibility? We will not be able to use .NET/VB.NET/C# since the application is supposed to work inside containers and containers may not support latest .NET runtime. Any other language is best fit for Active X control development other than VB and VC++?

• How to create a test environnement on the production FTP

  - by Clement Herreman

  Hello, I'm currently working on a symfony webapp, which is already on production. To develop and add/delete/modify functionnality of the model, I work on my laptop, using symfony 'dev' environnemment. I test if everything work fine, then I pray a little and deploy it on the prod server (with all the risk of data error, like when I add new not null attributes on the model, prod server configuration special stuff, version of php/apache etc.). The problem is that I would like to setup a "staging" server, which would be a copy of the production server (same database, same configuration apache/php), so that, if the deployment goes bad, the production user stay untouched and working, only the staging server is down. But my client has only 1 FTP available. So, the question is : can I run 2 symfony project, with different models, on the same FTP ? Or is there another way to do what I want to do ? Thank you !

• OJB / Oracle XE sql debug-display problem

  - by Jay

  Hello, I have a Java application, and use OJB as my ORM technology. I have an Oracle XE installation locally to develop against. The problem is when I need to debug a problem, I like looking at the SQL output. Here is an example of SQL I can view through the "Top SQL" interface in Oracle XE: select a_bunch_of_fields from KREW_DOC_TYP_T A0 WHERE ((UPPER(A0.DOC_TYP_NM) LIKE :1) AND A0.ACTV_IND = :2) AND A0.CUR_IND = :3 The problem is I would like to see the real value instead of ":1". I can't seem to find how I can configure this. I know the real values are working, because the application is responding as expected, for the most part (hence the bugs I am working on). Thanks, Jay

• Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

  - by ?????

  My catalina logs are filling up with gobs of statements like: /logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4] [0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb] [0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8] on and on forever. I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here: http://hc.apache.org/httpclient-3.x/logging.html And I don't see where this logging as been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it. Any ideas? I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

• What some good PHP jobs?

  - by ggfan

  I am no professional PHP coder or anything, in fact I am fairly new. I can develop sites but nothing too crazy or fancy with PHP,Mysql,CSS,HTML,javascript. Up to now, all I have been doing is practice coding from books and websites. I am now looking for a 'real-life' experience. Besides going to a company and getting an interview, are there any other options in which I can get paid to code? I have posted some ads on craiglists but that's about it. And because this is my first time going to the 'real-word' and can make mistakes, am I liable if...a site I made for someone gets hacked and that person losses information?

• dynamic silverlight content

  - by Jeremy

  I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

• How to iterate over an array of objects without foreach and ArrayAccess

  - by kenny99

  Hi, I'm having to develop a site on PHP 5.1.6 and I've just come across a bug in my site which isn't happening on 5.2+. When using foreach() to iterate over an object, I get the following error: "Fatal error: Objects used as arrays in post/pre increment/decrement must return values by reference..." Does anyone know how to convert the following foreach loop to a construct which will work with 5.1.6? Thanks in advance! foreach ($post['commercial_brands'] as $brand) { $comm_food = new Commercial_food_Model; $comm_food->brand = $brand; $comm_food->feeding_type_id = $f_type->id; $comm_food->save(); }

• Java: implementation of simple commands

  - by HH

  I have created a pkg for my regular simple commands. They are non-static, to be more extensible, but somewhat more time-consuming to use because of creating object to use one. My other classes use them. $ ls *.java CpF.java IsBinary.java RmLn.java Tools.java F2S.java IsRoot.java SaveToDisk.java WordCount.java Filters.java ModRelativePaths.java SetWord.java WordNumber.java Find.java powerTools.java Sort.java Which option would you choose to use them easier? to develop a small interface like 'powerTools.java' for the pkg. to create a class with static methods for them. to add a static method to each class to stop overusing 'creating too many files' and centralising some? sthing else?

• scrollable tab bar widget solution

  - by opensas

  I have a web page that I use to update a fairly complex data structure. The page itself has lots of information, so I developed some simple Tab-page control, with plain html. Each tab is a different page, so when the user click on a tab a post is issued to the new page. Fairly simply. The problem is that the page has about 10 tabs, so it no longer fits on screens. I'd like to know if you can advice some way to develop a scrollable tab bar or any other way to overcome this situation. maybe a widget or something... thanks a lot saludos sas

• Any editors to visually modify Wix templates?

  - by user1632018

  I have tried wixedit and sharp develop and from what I can tell they do not allow you to visually modify the premade templates with a designer. They only allow you to create your own customized dialogs that you can design yourself. So I am wondering if there is any editors that you can visually modify the design of these templates, especially the mondo template with a point and click editor. I have also tried SharpSetup and it looks promising how you can design the interface in visual studio, although since I don't know much about editing wix I am having a hard time comming up with the wix code to make it work.

• 3G/Edge/GPRS IP addresses and geocoding

  - by LookitsPuck

  Hey all! So, we're looking to develop a mobile website. On this mobile website, we'd like to automatically populate a user's location (with proper fallback) based on their IP address. I'm aware of geocoding a location based on IP address (mapping to latitude, longitude and then getting the location with that information). However, I'm curious how accurate this information is? Are mobile devices assigned IP's when they utilize 3G, EDGE, and GPRS connections? I think so. If that is so, does it map to a relatively accurate location? It doesn't have to be spot on, but relatively accurate would be nice. Thanks! -Steve

• What is the best tool to achieve this API design?

  - by Jose Fernandez

  Our web app offers a service that allows a "Publisher" to create a website (we give them a CMS system) that is ready to provide this service to "Members" (think Shopify). We have some possible clients that wish to become "Publishers" but they already have existing websites (vbulletin, word press blog, etc) with their own user base. We wish to develop an API that would allow these "Publishers" to keep using their own websites, and embed our services into them. Our main business requirement is that once "Members" are logged into the "Publishers" existing system, they should be able to also access our website without having to log-in again OR have to create another account there. The process should be seamless to the "Member" and "Publishers" should not have to sync their user base with our system. We also want to use an existing API authentication/authorization system instead of creating our own (OAuth, OpenID, etc) What would be the best way to use OAuth to achieve this sigle-sign on design? If OAuth is not the best tool, is there any other one out there that fits our requirements?

• Which Java web frameworks provide hot-reload?

  - by Stefane Fermigier

  I'd like to know which Java web application frameworks do provide a "hot reload" capability, i.e. allow to develop applications and have them redeployed on the server "almost instantly" (i.e. in less than a few seconds). I the Java world, Play! has it out of the box, but what I'm looking for is a more exhaustive list. Other examples that I'm aware of include: Nuxeo WebEngine, provided you're using Eclipse and the right plugin, or, in the Python world, Django and Pylons (when using the "--reload" option).

• Strategy for developing namespaced and non-namespaced versions of same PHP code

  - by porneL

  I'm maintaining library written for PHP 5.2 and I'd like to create PHP 5.3-namespaced version of it. However, I'd also keep non-namespaced version up to date until PHP 5.3 becomes so old, that even Debian stable ships it ;) I've got rather clean code, about 80 classes following Project_Directory_Filename naming scheme (I'd change them to \Project\Directory\Filename of course) and only few functions and constants (also prefixed with project name). Question is: what's the best way to develop namespaced and non-namespaced versions in parallel? Should I just create fork in repository and keep merging changes between branches? Are there cases where backslash-sprinkled code becomes hard to merge? Should I write script that converts 5.2 version to 5.3 or vice-versa? Should I use PHP tokenizer? sed? C preprocessor? Is there a better way to use namespaces where available and keep backwards compatibility with older PHP?
