• displaying .aspx and .aspx.cs files such that its not understood by the browser

  - by user287745

  i have to give the user the option to upload his own aspx and aspx.cs files on to the server, adjust the hyperlink to point to a page which would do the following display the aspx and aspx.cs files code onto the page without actually rendering the code the browser should not understand anything, and while reading the files to display them the method be such that nothing is processed on the server regarding the code within the files to prevent from unnecessary problems many user would try to cause. i have tried many ways of displaying it but it ends up on displaying the actual comments instead of the code. please suggest with links to examples how to achieve the above. please note main concentration is on asp.net and c# using vs08, so j script and ready-made tools be avoided if feasible thank you all

• What is the C# equivalent of java.util.regex?

  - by peter.murray.rust

  I am converting Java code to C# and need to replace the use of Java's regex. A typical use is import java.util.regex.Matcher; import java.util.regex.Pattern; //... String myString = "B12"; Pattern pattern = Pattern.compile("[A-Za-z](\\d+)"); Matcher matcher = Pattern.matcher(myString); String serial = (matcher.matches()) ? matcher.group(1) : null; which should extract a capture group from a matched target string. I'd be grateful for simple examples. EDIT: I have now added the C# equivalent of the code as an answer. EDIT: Here is a tutorial on the use of the actual expressions. EDIT: Here is a useful comparison of C# and Java (and Perl.)

• JSON to Persistent Data Store (CoreData, etc.)

  - by Bryan Veloso

  All of the data on my application is pulled through an API via JSON. The nature of a good percentage of this data is that it doesn't change very often. So to go and make JSON requests to get a list of data that doesn't change much didn't seem all that appealing. I'm looking for the most sensible option to have this JSON saved onto the iPhone in some sort of persistent data store. Obviously one plus of persisting the data would be to provide it when the phone can't access the API. I've looked at a few examples of having JSON and CoreData interact, for example, but it seems that they only describe transforming NSManagedObjects into JSON. If I can transform JSON into CoreData, my only problem would be being able to change that data when the data from the API does change. (Or, maybe this is all just silly.)

• Why would I do an inner join on a non-distinct field?

  - by froadie

  I just came across a query that does an inner join on a non-distinct field. I've never seen this before and I'm a little confused about this usage. Something like: SELECT distinct all, my, stuff FROM myTable INNER JOIN myOtherTable ON myTable.nonDistinctField = myOtherTable.nonDistinctField (WHERE some filters here...) I'm not quite sure what my question is or how to phrase it, or why exactly this confuses me, but I was wondering if anyone could explain why someone would need to do an inner join on a non-distinct field and then select only distinct values...? Is there ever a legitimate use of an inner join on a non-distinct field? What would be the purpose? And if there's is a legitimate reason for such a query, can you give examples of where it would be used?

• Direct3D 11 effect files deprecated?

  - by Toji

  I've been playing around with Direct3D 11 a little bit lately and have been frustrated by the lack of documentation on the basics of the API (such as simple geometry rendering). One of the points of confusion brought on by the sparse documentation is the (apparent) move away from the use of effects for shaders. In D3D11 all of the effect (.fx) support has been removed from the D3DX libraries and buried away in a hard to find (sparsely documented, of course) shared source library. None of the included examples use it, preferring instead to compile HLSL files directly. All of this says to me that Microsoft is trying to get people to stop using the effect file format. Is that true? Is there any documentation of any kind that states that? I'm fine doing it either way, but for years now they've been promoting the .fx format so it seems odd that they would suddenly decide to drop it.

• How to implement filter system in SQL?

  - by sadvaw

  Right now I am planning to add a filter system to my site. Examples: (ID=apple, COLOR=red, TASTE=sweet, ORIGIN=US) (ID=mango, COLOR=yellow, TASTE=sweet, ORIGIN=MEXICO) (ID=banana, COLOR=yellow, TASTE=bitter-sweet, ORIGIN=US) so now I am interested in doing the following: SELECT ID FROM thisTable WHERE COLOR='yellow' AND TASTE='SWEET' But my problem is I am doing this for multiple categories in my site, and the columns are NOT consistent. (like if the table is for handphones, then it will be BRAND, 3G-ENABLED, PRICE, COLOR, WAVELENGTH, etc) how could I design a general schema that allows this? Right now I am planning on doing: table(ID, KEY, VALUE) This allows arbitary number of columns, but for the query, I am using SELECT ID FROM table WHERE (KEY=X1 AND VALUE=V1) AND (KEY=X2 AND VALUE=V2), .. which returns an empty set. Can someone recommend a good solution to this? Note that the number of columns WILL change regularly

• How do I use Zend Cache on this particular problem

  - by davykiash

  I have an action that renders two different view scripts based on whether the user is logged in or not. class IndexController extends Zend_Controller_Action { .... public function indexAction() { $auth = Zend_Auth::getInstance(); if($auth->hasIdentity()) { $this->render('indexregistered'); return; } else { $this->render('indexpublic'); return; } } .... } I have seen quite some useful examples on how to use the Zend Cache and they seem to be based on the fact that the action renders one particular script. What am really looking at is the best approach to cache the the indexpublic script does get quite some hits and I would live to avoid the Zend MVC overhead if possible.

• Pulling out two separate words from a string using reg expressions?

  - by Marvin

  I need to improve on a regular expression I'm using. Currently, here it is: ^[a-zA-Z\s/-]+ I'm using it to pull out medication names from a variety of formulation strings, for example: SULFAMETHOXAZOLE-TRIMETHOPRIM 200-40 MG/5ML PO SUSP AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE AMOXICILLIN TRIHYDRATE 125 mg ORAL TABLET, CHEWABLE AMOX TR/POTASSIUM CLAVULANATE 125 mg-31.25 mg ORAL TABLET, CHEWABLE Amoxicillin 1000 MG / Clavulanate 62.5 MG Extended Release Tablet The resulting matches on these examples are: SULFAMETHOXAZOLE-TRIMETHOPRIM AMOX TR/POTASSIUM CLAVULANATE AMOXICILLIN TRIHYDRATE AMOX TR/POTASSIUM CLAVULANATE Amoxicillin The first four are what I want, but on the fifth, I really need "Amoxicillin / Clavulanate". How would I pull out patterns like "Amoxicillin / Clavulanate" (in fifth row) while missing patterns like "MG/5 ML" (in the first row)?

• How do I export and import application services with say MEF?

  - by John Leidegren

  I'm working with MEF right now, but the answer I'm looking for probably is irrelevant to MEF -- it's all dependency injection -- I'm just using MEF terminology as an example here. Short background story, I read this article over at MSDN with focus on Composite Applications In this figure there's three things, the shell, the application services and the modules. So that's a composite application. What I don't fully get is the application services part. What's the service, what does it look like? How do you expose a service through a module and how do you consume a service from a different module? I'd really like to see some neat small code examples, nothing fancy but something to illustrate how all this comes to life (the application services part).

• Java Jersey RESTful services

  - by pHk

  Rather new to REST and Jersey, and I'm trying out some basic examples. I've got one particular question though, which I haven't really found an answer for yet (don't really know how to look for this): how would you go about storing/defining common services so that they are stateful and accessible to all/some resources? For instance, a logger instance (Log4J or whatever). Do I have to manually initialize this and store it in the HttpSession? Is there a "best practice" way of doing this so that my logger is accessible to all/some resources? Thanks a lot.

• VSTS 2008 Load testing, Is it any good?

  - by anshu

  I have already spent couple of weeks trying to use this tool to generate some webtest and load test. But every day it throws a weird problem for which I do not find anything in document. examples: Hidden variables (_lastfocus) not found in the context error. Today, all of sudden it is now refusing to run some of the webtest which are part of the test mix in my load test run (is working fine with another load test). Are enterprise level, expensive tools are only good? (like loadrunner, silkperformer etc).

• Advanced command line argument parsing in Java?

  - by Bishop87

  Does anyone have any java examples for parsing a series of command line arguements in a robust way? I'm looking to be able to handle something like: java myapp [-l language] [-d int] [-f file1 file2 file3] I want to do this in a robust way so I can provide logical error messages to the user if they mistake a command line-option. Some of these options I'd like to make optional, etc, etc. Also, the -f file list should be able to handle a list of files. Is there some library out there to assist me in handling this?

• Modifying a model and texture mid-game code

  - by MicroPirate

  Just have a question for anyone out there who knows some sort of game engine pretty well. What I am trying to implement is some sort of script or code that will allow me to make a custom game character and textures mid-game. A few examples would be along the lines of changing facial expressions and body part positions in the game SecondLife. I don't really need a particular language, feel free to use your favorite, I'm just really looking for an example on how to go about this. Also I was wondering if there is anyway to combine textures for optimization; for example if i wanted to add a tattoo to a character midgame, is there any code that could combine his body texture and the tattoo texture into one texture to use (this way I can simply just render one texture per body.) Any tips would be appreciated, sorry if the question is a wee bit to vauge.

• How ASP.NET MVC passes model to the view without explicitly passing it

  - by Vlad Bezden

  Here is one of the examples that I've seen on how to do validation on Controller: [HttpPost] public ViewResult Create(MyModel response) { if (ModelState.IsValid) { return View("Thanks"); } else { return View(); } } If there are validation errors, than return View() method is called without any parameters. Obviesly you have @Html.ValidationSummary() in your View and Model has all required properties attributes. The data that was entered into the form was preserved and displayed again when the view was rendered with the validation summary. My question is how data preserved? Since it was not passed to the View like return View(response); Thanks a lot. Sincerely, Vlad

• Known "Z notation" applications ?

  - by Amadeus45

  I was just remembering back my university classes and was wondering to know if anyone out here even used the "Z notation" in a professional environment. I honestly must say that it was the single most boring class that I have ever attended in my life. Maybe because of the teacher, but at the time we really all thought it was a big waste of time. I might have been wrong, which is why I'd like to hear you about it. If you are using it or some derived language (Z++), I'd just like to know how is it useful for you. Just curious to know some commonly-known applications of Z or your application. For those who are not familiar : http://staff.washington.edu/jon/z/z-examples.html

• Google maps nearest points avoiding rivers / by itinerary

  - by Karl Lacroix

  Here is the deal : I need to find the closest points from a point with a radius. For example, I need to get all the points in a 15 km radius. Thats easy with Google Maps Radius and all the examples on the web ;) The problem is that from my office, a point is under the 15km radius, but it's on the other side of a river, so the car itinerary is about 30 km (using a bridge)! Is there a simple solution to exclude those points or to calculate by intineraries ? I supposed that I'll need to calculate all itineraries with returned points? DirectionsRequest API? Thanks! :)

• Example of tree.drop_mode with jQuery sortable anywhere

  - by fred

  Hello Everyone, I have a working tree of galleries next to a sortable list of image thumbnails. I've been vainly trying to set up the galleries tree so that users can add images to the galleries by dropping the sortable thumbnails on to the galleries tree. I've been told this requires drop_mode. All efforts to get it to work have failed and I can't really make heads or tails of the drop_mode documentation. I've sought out some working examples via Google of just such an application but have failed. Can anyone point me to a working example of either a draggable or sortable list that successfully drops on to a tree and passes along some parameters between the two? Thanks!

• Image processing in a multhithreaded mode using Java

  - by jadaaih

  Hi Folks, I am supposed to process images in a multithreaded mode using Java. I may having varying number of images where as my number of threads are fixed. I have to process all the images using the fixed set of threads. I am just stuck up on how to do it, I had a look ThreadExecutor and BlockingQueues etc...I am still not clear. What I am doing is, - Get the images and add them in a LinkedBlockingQueue which has runnable code of the image processor. - Create a threadpoolexecutor for which one of the arguements is the LinkedBlockingQueue earlier. - Iterate through a for loop till the queue size and do a threadpoolexecutor.execute(linkedblockingqueue.poll). - all i see is it processes only 100 images which is the minimum thread size passed in LinkedBlockingQueue size. I see I am seriously wrong in my understanding somewhere, how do I process all the images in sets of 100(threads) until they are all done? Any examples or psuedocodes would be highly helpful Thanks!

• How to handle downgrade subscription for SaaS application

  - by user635800

  I am currently launching a SaaS web application. I want to have subscription packages such as: Premium: 5 users, 20 widgets, 20 MB storage Basic: 2 users, 10 widgets, 50 MB storage I want to allow companies to upgrade and downgrade packages at any time. The problem I am having is what if the company is on the premium package and has 5 users, 20 widgets, and wants to downgrade to the "basic" package. How do I handle that? Do I flag an error and say "You cannot downgrade" or do I take them to a page to remove the "extra" users and widgets? Any advice or examples of how other companies do it would be great!!

• OpenDACS .Net Framework

  - by Goober

  Scenario As some of you may have heard, OpenDACS is an open source data-access control system for enforcing data usage permissions. DACS comes integrated with the Reuters platform but you can use OpenDACS for extending third-party software. I'm using IE6, I can't embed these links properly. http://thomsonreuters.com/products_services/financial/financial_products/real-time/data_access_control_system https://customers.reuters.com/developer/Kits/OpenDACS/opendacs.aspx Question Has anyone used OpenDACS at all? I'm quite interested in it but I have no idea where to start. Ideally some examples would be fantastic, or a startup guide. Thoughts I use C# heavily and am looking to extend a C# application with DACS. I understand that there is currently no C# API, however I've heard that the SFC-COM Edition can used with the .Net/COM interoperability layer Help greatly appreciated. Cheers.

• More complex view matrix calculation required to composite 3d models with 2d video

  - by lzcd

  I'm utilising some 2d / 3d tracking data (provided by pfHoe) to help integrate some 3d models into the playback of some 2d video. Things are working.... okay... but there's still some visible 'slipping' of the models against the video background and I suspect this is may be because the XNA CreatePerspective helper method isn't taking into account some of the additional data supplied by pfHoe such as independent horizontal / vertical field of view angles and focal length. Would anyone be able to point me towards some examples of constructing view matrices that include such details?
