  • How do I iterate over the properties of an anonymous object in C#?

    - by Tomas Lycken
    I want to take an anonymous object as argument to a method, and then iterate over its properties to add each property/value to a a dynamic ExpandoObject. So what I need is to go from new { Prop1 = "first value", Prop2 = SomeObjectInstance, Prop3 = 1234 } to knowing names and values of each property, and being able to add them to the ExpandoObject. How do I accomplish this? Side note: This will be done in many of my unit tests (I'm using it to refactor away a lot of junk in the setup), so performance is to some extent relevant. I don't know enough about reflection to say for sure, but from what I've understood it's pretty performance heavy, so if it's possible I'd rather avoid it... Follow-up question: As I said, I'm taking this anonymous object as an argument to a method. What datatype should I use in the method's signature? Will all properties be available if I use object?

  • What Makes a Good Design Critic? CHI 2010 Panel Review

    - by jatin.thaker
    Author: Daniel Schwartz, Senior Interaction Designer, Oracle Applications User Experience Oracle Applications UX Chief Evangelist Patanjali Venkatacharya organized and moderated an innovative and stimulating panel discussion titled "What Makes a Good Design Critic? Food Design vs. Product Design Criticism" at CHI 2010, the annual ACM Conference on Human Factors in Computing Systems. The panelists included Janice Rohn, VP of User Experience at Experian; Tami Hardeman, a food stylist; Ed Seiber, a restaurant architect and designer; John Kessler, a food critic and writer at the Atlanta Journal-Constitution; and Larry Powers, Chef de Cuisine at Shaun's restaurant in Atlanta, Georgia. Building off the momentum of his highly acclaimed panel at CHI 2009 on what interaction design can learn from food design (for which I was on the other side as a panelist), Venkatacharya brought together new people with different roles in the restaurant and software interaction design fields. The session was also quite delicious -- but more on that later. Criticism, as it applies to food and product or interaction design, was the tasty topic for this forum and showed that strong parallels exist between food and interaction design criticism. Figure 1. The panelists in discussion: (left to right) Janice Rohn, Ed Seiber, Tami Hardeman, and John Kessler. The panelists had great insights to share from their respective fields, and they enthusiastically discussed as if they were at a casual collegial dinner. John Kessler stated that he prefers to have one professional critic's opinion in general than a large sampling of customers, however, "Web sites like Yelp get users excited by the collective approach. People are attracted to things desired by so many." Janice Rohn added that this collective desire was especially true for users of consumer products. Ed Seiber remarked that while people looked to the popular view for their target tastes and product choices, "professional critics like John [Kessler] still hold a big weight on public opinion." Chef Powers indicated that chefs take in feedback from all sources, adding, "word of mouth is very powerful. We also look heavily at the sales of the dishes to see what's moving; what's selling and thus successful." Hearing this discussion validates our design work at Oracle in that we listen to our users (our diners) and industry feedback (our critics) to ensure an optimal user experience of our products. Rohn considers that restaurateur Danny Meyer's book, Setting the Table: The Transforming Power of Hospitality in Business, which is about creating successful restaurant experiences, has many applicable parallels to user experience design. Meyer actually argues that the customer is not always right, but that "they must always feel heard." Seiber agreed, but noted "customers are not designers," and while designers need to listen to customer feedback, it is the designer's job to synthesize it. Seiber feels it's the critic's job to point out when something is missing or not well-prioritized. In interaction design, our challenges are quite similar, if not parallel. Software tasks are like puzzles that are in search of a solution on how to be best completed. As a food stylist, Tami Hardeman has the demanding and challenging task of presenting food to be as delectable as can be. To present food in its best light requires a lot of creativity and insight into consumer tastes. It's no doubt then that this former fashion stylist came up with the ultimate catch phrase to capture the emotion that clients want to draw from their users: "craveability." The phrase was a hit with the audience and panelists alike. Sometime later in the discussion, Seiber remarked, "designers strive to apply craveability to products, and I do so for restaurants in my case." Craveabilty is also very applicable to interaction design. Creating straightforward and smooth workflows for users of Oracle Applications is a primary goal for my colleagues. We want our users to really enjoy working with our products where it makes them more efficient and better at their jobs. That's our "craveability." Patanjali Venkatacharya asked the panel, "if a design's "craveability" appeals to some cultures but not to others, then what is the impact to the food or product design process?" Rohn stated that "taste is part nature and part nurture" and that the design must take the full context of a product's usage into consideration. Kessler added, "good design is about understanding the context" that the experience necessitates. Seiber remarked how important seat comfort is for diners and how the quality of seating will add so much to the complete dining experience. Sometimes if these non-food factors are not well executed, they can also take away from an otherwise pleasant dining experience. Kessler recounted a time when he was dining at a restaurant that actually had very good food, but the photographs hanging on all the walls did not fit in with the overall décor and created a negative overall dining experience. While the tastiness of the food is critical to a restaurant's success, it is a captivating complete user experience, as in interaction design, which will keep customers coming back and ultimately making the restaurant a hit. Figure 2. Patanjali Venkatacharya enjoyed the Sardinian flatbread salad. As a surprise Chef Powers brought out a signature dish from Shaun's restaurant for all the panelists to sample and critique. The Sardinian flatbread dish showcased Atlanta's taste for fresh and local produce and cheese at its finest as a salad served on a crispy flavorful flat bread. Hardeman said it could be photographed from any angle, a high compliment coming from a food stylist. Seiber really enjoyed the colors that the dish brought together and thought it would be served very well in a casual restaurant on a summer's day. The panel really appreciated the taste and quality of the different components and how the rosemary brought all the flavors together. Seiber remarked that "a lot of effort goes into the appearance of simplicity." Rohn indicated that the same notion holds true with software user interface design. A tremendous amount of work goes into crafting straightforward interfaces, including user research, prototyping, design iterations, and usability studies. Design criticism for food and software interfaces clearly share many similarities. Both areas value expert opinions and user feedback. Both areas understand the importance of great design needing to work well in its context. Last but not least, both food and interaction design criticism value "craveability" and how having users excited about experiencing and enjoying the designs is an important goal. Now if we can just improve the taste of software user interfaces, people may choose to dine on their enterprise applications over a fresh organic salad.

  • Having trouble with Regular Expression and Ampersand

    - by ajax81
    Hi All, I'm having a bit of trouble with regex's (C#, ASP.NET), and I'm pretty sure I'm doing something fundamentally wrong. My task is to bind a dynamically created gridview to a datasource, and then iterate through a column in the grid, looking for the string "A&I". An example of what the data in the cell (in template column) looks like is: Name: John Doe Phone: 555-123-1234 Email: john[email protected] Dept: DHS-A&I-MRB Here's the code I'm using to find the string value: foreach(GridViewRow gvrow in gv.Rows) { Match m = Regex.Match(gvrow.Cells[6].Text,"A&I"); if(m.Success) { gvrow.ForeColor = System.Drawing.Color.Red; } } I'm not having any luck with any of these variations: "A&I" "[A][&][I]" But when I strictly user "&", the row does turn red. Any suggestions? Thanks, Dan

    I have a schema like : employees (eno, ename, zip, hdate) customers (cno, cnmae, street, zip, phone) zipcodes (zip, city) where zip is pk in zipcodes and fk in other tables. I have to write an update query which updates all the occurence of zipcode 4994 to 1234 throughout the database. update zipcodes,customers,employees set zip = 0 where customers.zip = zipcodes.zip and employees.zip = zipcodes.zip; but i know i am not doing it right. Is there a way to update all the tables zip ina single update query?

  • Navigate touch-tone menus via modem

    - by Kongress
    I have a system that I need to programmatically interface with that requires a set of numbers to be dialed after the phone line is picked up, like a standard automated phone answering system. For instance, dial the number 123-456-7890, wait for the line to be answered, wait 15 seconds for the voice prompt, dial 1234#, hang up. The question is, can I and how do I do that through a modem? I know how to dial a number through a modem, it's simply ATDT[phone number], but that will attempt to initiate a data connection which will not allow touch-tone number entry. Would a voice modem provide the necessary capability? If so, could anyone provide example commands to accomplish this?

  • Integer comparison as string

    - by J Pollack
    Hi I have an integer column and I want to find numbers that start with specific digits. For example they do match if I look for '123': 1234567 123456 1234 They do not match: 23456 112345 0123445 Is the only way to handle the task by converting the Integers into Strings before doing string comparison? Also I am using Postgre regexp_replace(text, pattern, replacement) on numbers which is very slow and inefficient way doing it. The case is that I have large amount of data to handle this way and I am looking for the most economical way doing this.

  • Convert XML namespace prefixes with C#?

    - by jrista
    I have run into an exasperating problem getting a Java service client to communicate successfully with a WCF service. I have overcome many hurdles, and I believe that this is my last one. The problem boils down to how Java Axis + WSS4J seem to handle xml namespaces. The Java platform seem to be very rigid in what they expect for xml namespace prefixes, and as such, do not understand the WCF reply messages. My problem in a nutshell is as follows. I have an xml response similar to the following from my WCF service: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <s:Header> <a:Action s:mustUnderstand="1" u:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</a:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <a:RelatesTo u:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <o:Security s:mustUnderstand="1" xmlns:o="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </o:Security> </s:Header> <s:Body u:Id="_1"> <e:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:e="http://www.w3.org/2001/04/xmlenc#"> <e:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <e:CipherData> <e:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</e:CipherValue> </e:CipherData> </e:EncryptedData> </s:Body> </s:Envelope> This response uses simple one-character namespace prefixes for most things, such as 's' for SOAP Envelope, 'a' for WS-Addressing, 'o' for 'WS-Security', etc. The Java client, namely WSS4J, seems to expect the following: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <soap:Header> <wsa:Action soap:mustUnderstand="1" wsu:Id="_3">http://tempuri.org/IProcessor/DoProcessingResponse</wsa:Action> <h:CorrelationID xmlns:h="http://tempuri.org/">1234</h:CorrelationID> <wsa:RelatesTo wsu:Id="_4">uuid:40f800a0-9613-4f4a-96c5-b9fd98085deb</a:RelatesTo> <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <!-- WS-Security header stuff --> </wsse:Security> </soap:Header> <soap:Body u:Id="_1"> <xenc:EncryptedData Id="_2" Type="http://www.w3.org/2001/04/xmlenc#Content" xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"> <xenc:EncryptionMethod Algorithm="http://www.w3.org/2001/04/xmlenc#aes128-cbc"/> <xenc:CipherData> <xenc:CipherValue>NfA6XunmyLlT2ucA+5QneoawHm+imcaCltDAJC1mRZOSxoB6YGpDLY1FyVykPbPGDoFGUESLsmvvbD62sNnRrgE+AuKPo+1CD3DF4LfurRcEv9A50ba9V+ViqlrhydhK</xenc:CipherValue> </xenc:CipherData> </xenc:EncryptedData> </soap:Body> </soap:Envelope> Upon receipt of my response message, the Java client and WSS4J seem to want to look up elements by their own internal xml aliases, such as 'wsa' for WS-Addressing, and 'wsse' for WS-Security Extensions. Since neither of those namespaces are present in the actual response xml, exceptions are thrown. I am wondering if there is any simple way to transform an xml document from one set of namespaces to another set using C#, .NET, and the System.Xml namespace. I've poked around with XmlNamespaceManager a bit, but it does not seem to fully support what I need...or at least, I have been unable to find any really useful examples, and am not fully sure how it works. I am trying to avoid having to write some heavy-duty process to handle this manually myself, as I do not want to drastically impact the performance of our services when called by a Java Axis/WSS4J client.

  • Concatenation with Zero is not occurring properly in code?

  • SQL Server won't perform regular expression validation on XML column

    - by Kirk Broadhurst
    Hi I have an XML column in my table which contains this xsd snippet: <xsd:element name="Postcode" minOccurs="0"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:pattern value="^[0-9]{4}$" /> </xsd:restriction> </xsd:simpleType> </xsd:element> The regular expression should require a string containing 4 numerical digits. It validates perfectly in Visual Studio and is a correct regular expression. SQL Server, on the other hand, won't accept it. The error message I receive is: XML Validation: Invalid simple type value: '1234'. Location: / * : Donor[1]/*:Postcode[1]. I have an email address regex working fine, but can't get this simple numerical regex to work.

  • paperclip callbacks or simple processor?

    - by holden
    I wanted to run the callback after_post_process but it doesn't seem to work in Rails 3.0.1 using Paperclip 2.3.8. It gives an error: undefined method `_post_process_callbacks' for #<Class:0x102d55ea0> I want to call the Panda API after the file has been uploaded. I would have created my own processor for this, but as Panda handles the processing, and it can upload the files as well, and queue itself for an undetermined duration I thought a callback would do fine. But the callbacks don't seem to work in Rails3. after_post_process :panda_create def panda_create video = Panda::Video.create(:source_url => mp3.url.gsub(/[?]\d*/,''), :profiles => "f4475446032025d7216226ad8987f8e9", :path_format => "blah/1234") end I tried require and include for paperclip in my model but it didn't seem to matter. Anyideas?

  • Reading a Windows 'binary' float into a ASP jscript variable

    - by user89691
    I need to read files produced by a legacy Windows app that stores real numbers (the 8-byte "double" type) in binary - i.e. as a packed array of 8 bytes. I can read the 8 byte group OK but how can I present it to my ASP JScript code such I can get the real number back again. Or to put it another way: Say a file was produced by a Windows (Delphi) program: Assign (f, 'test.bin') ; rewrite (f, 1) ; r := 1234.56E78 ; BlockWrite (f, r, SizeOf (Double)) ; Close (f) ; Inspection of the file will show it contains 8 bytes, being: 94 0E 4C CA C2 97 AD 53 which is the real number in IEEE format. Assuming I can read these 8 bytes back in ASP, is there a simple way of getting the real number back again?

    I'm getting myself acquainted with ASP.Net-MVC, and I was trying to accomplish some common tasks I've accomplished in the past with webforms and other functionality. On of the most common tasks I need to do is create SEO-friendly urls, which in the past has meant doing some url rewriting to build the querystring into the directory path. for example: www.somesite.com/productid/1234/widget rather than: www.somesite.com?productid=1234&name=widget What method do I use to accomplish this in ASP.Net-MVC?

  • problem processing xml in flex3

    - by john
    Hi All, First time here asking a question and still learning on how to format things better... so sorry about the format as it does not look too well. I have started learning flex and picked up a book and tried to follow the examples in it. However, I got stuck with a problem. I have a jsp page which returns xml which basically have a list of products. I am trying to parse this xml, in other words go through products, and create Objects for each product node and store them in an ArrayCollection. The problem I believe I am having is I am not using the right way of navigating through xml. The xml that is being returned from the server looks like this: <?xml version="1.0" encoding="ISO-8859-1"?><result type="success"> <products> <product> <id>6</id> <cat>electronics</cat> <name>Plasma Television</name> <desc>65 inch screen with 1080p</desc> <price>$3000.0</price> </product> <product> <id>7</id> <cat>electronics</cat> <name>Surround Sound Stereo</name> <desc>7.1 surround sound receiver with wireless speakers</desc> <price>$1000.0</price> </product> <product> <id>8</id> <cat>appliances</cat> <name>Refrigerator</name> <desc>Bottom drawer freezer with water and ice on the door</desc> <price>$1200.0</price> </product> <product> <id>9</id> <cat>appliances</cat> <name>Dishwasher</name> <desc>Large capacity with water saver setting</desc> <price>$500.0</price> </product> <product> <id>10</id> <cat>furniture</cat> <name>Leather Sectional</name> <desc>Plush leather with room for 6 people</desc> <price>$1500.0</price> </product> </products></result> And I have flex code that tries to iterate over products like following: private function productListHandler(e:JavaFlexStoreEvent):void { productData = new ArrayCollection(); trace(JavaServiceHandler(e.currentTarget).response); for each (var item:XML in JavaServiceHandler(e.currentTarget).response..product ) { productData.addItem( { id:item.id, item:item.name, price:item.price, description:item.desc }); } } with trace, I can see the xml being returned from the server. However, I cannot get inside the loop as if the xml was empty. In other words, JavaServiceHandler(e.currentTarget).response..product must be returning nothing. Can someone please help/point out what I could be doing wrong. My JavaServiceHandler class looks like this: package com.wiley.jfib.store.data { import com.wiley.jfib.store.events.JavaFlexStoreEvent; import flash.events.Event; import flash.events.EventDispatcher; import flash.net.URLLoader; import flash.net.URLRequest; public class JavaServiceHandler extends EventDispatcher { public var serviceURL:String = ""; public var response:XML; public function JavaServiceHandler() { } public function callServer():void { if(serviceURL == "") { throw new Error("serviceURL is a required parameter"); return; } var loader:URLLoader = new URLLoader(); loader.addEventListener(Event.COMPLETE, handleResponse); loader.load(new URLRequest(serviceURL)); // var httpService:HTTPService = new HTTPService(); // httpService.url = serviceURL; // httpService.resultFormat = "e4x"; // httpService.addEventListener(Event.COMPLETE, handleResponse); // httpService.send(); } private function handleResponse(e:Event):void { var loader:URLLoader = URLLoader(e.currentTarget); response = XML(loader.data); dispatchEvent(new JavaFlexStoreEvent(JavaFlexStoreEvent.DATA_LOADED) ); // var httpService:HTTPService = HTTPService(e.currentTarget); // response = httpService.lastResult.product; // dispatchEvent(new JavaFlexStoreEvent(JavaFlexStoreEvent.DATA_LOADED) ); } } } Even though I refer to this as mine and it is not in reality. This is from a Flex book as a code sample which does not work, go figure. Any help is appreciated. Thanks john

  • Ruby Socket Inheritance

    - by Jarsen
    I'm writing a Ruby class that extends TCPSocket. Assume it looks something like this: class FooSocket < TCPSocket def hello puts 'hello' end end I have a TCPServer listening for incoming connections server = TCPServer.new 1234 socket = server.accept When my server finally accepts a connection, it will return a TCPSocket. However, I want a FooSocket so that I can call socket.hello. How can I change TCPSocket into a FooSocket? I could duck-punch the methods and attributes I want directly onto the TCPSocket class, but I'm using it elsewhere and so I don't want to do that. Probably the easiest solution is to write a class that encapsulates a TCPSocket, and just pass the socket returned by accept as a param. However, I'm interested to know how to do it through inheritance—I've been trying to bend my mind around it but can't figure it out. Thanks in advance.

  • VARCHAR does not work as expected in Apache Derby

    - by Tom Brito
    I'm having this same problem: How can I truncate a VARCHAR to the table field length AUTOMATICALLY in Derby using SQL? To be specific: CREATE TABLE A ( B VARCHAR(2) ); INSERT INTO A B VALUES ('1234'); would throw a SQLException: A truncation error was encountered trying to shrink VARCHAR '123' to length 2. that is already answered: No. You should chop it off after checking the meta-data. Or if you don't wanna check the meta-data everytime, then you must keep both your code and database in sync. But thats not a big deal, its a usual practice in validators. but my doubt is: isn't VARCHAR suppose to variate its size to fit the data? What's wrong with apache derby's VARCHAR?

  • Generating a error code per property in Hibernate validator

    Hi all, I am looking at using hibernate validator for a requirement of mine. I want to validate a bean where properties may have multiple validation checks. e.g. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) private String myProperty; } But if this property fails validation I want a specific error code to be associated with the ConstraintViolation, regardless of whether it failed because of @Required or @Length, although I would like to preserve the error message. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) @ErrorCode( "1234" ) private String myProperty; } Something like the above would be good but it doesn't have to be structured exactly like that. I can't see a way to do this with hibernate validator. Is it possible? Thanks.

  • regex partial match for several different groups

    - by koral
    I need regexp to match string build from several groups (A is any letter, 9 is any digit): group 1 regex [A-Z]{1,2}[0-9]? A A9 AA9 group 2 regex [A-Z]{1,3}[0-9]? A AA AAA AAA9 group 3 regex [A-Z]{2,3}[0-9]?[A-Z]? AAA AA9 AA9A group 4 regex [0-9]{1,2}[A-Z]{1,2}[0-9]? 9A 9AA 9A9 99A9 Not each group must be present but there must be all in correct order - I mean (digit is group number): 1 12 123 1234 So if there is present group 3 there must me all preceding groups present also. As there are four groups (can be more), so alternative like ^[A-Z]{1,2}[0-9]{1}|[A-Z]{1,2}[0-9]{1}\s{1}[A-Z]{1}[0-9]?$ is not the best option as it would be complicated and difficult to maintain. Is there any solution with groups or something? The order of groups is important.

  • Is there any way to simplify a verbose SQL INSERT INTO(..) query?

    - by Soundar Rajan
    I have a table with one id (autonumber) field and 50 other fields. The table is normalized, these are 50 material properties etc. I want to copy a record from this table into the same table - only the autoincrement id will be different. The query I am using now is INSERT INTO tableName (field1,field2,....field50) SELECT field1,field2,....field50 from tableName WHERE autoid=1234; Note that I have to type in ALL the 50 field names, twice! Is there any way to shorten this query so I don't have to type all of them? Thanks.

  • Uploading a picture to a album using the graph api

    - by kielie
    Hi guys, I am trying to upload an image to a album, but it's not working, here is the code I am using, $uid = $facebook->getUser(); $args = array('message' => $uid); $file_path = "http://www.site.com/path/to/file.jpg"; $album_id = '1234'; $args['name'] = '@' . realpath($file_path); $data = $facebook->api('/'. $album_id . '/photos', 'post', $args); print_r($data); This code is in a function.php file that gets called when a user clicks on a button inside of a flash file that is embedded on my canvas, so basically what I want it to do is, when the flash takes a screen shot and passes the variable "image" to the function, it should upload $_GET['image'] to the album. How could I go about doing this? Thanx in advance!

  • Visual Studio ASP.Net MVC undo set as start page action

    - by kingrichard2005
    I have an web application that I'm working on, it was working fine until my curiosity got the better of me and I right-clicked on a view and chose Set As Start Page option. Now, whenever I run my application it takes me to the Resource Not Found error page. I have the default register route set in my Global config route which was working fine before. I notice that the URL now reads: http://localhost:1234/Views/User/Login.aspx instead of http://localhost:1234/ like it was before. I'm not sure how to undo this action or what was changed, I've looked in my web.config file but I'm not sure what to look for exactly, Help is appreciated.

  • ASP.NET MVC: post-redirect-get pattern, with only two overloaded action methods

    - by Rafi
    Is it possible to implement post-redirect-get pattern, with two overloaded action methods(One for GET action and the other for POST action) in ASP.NET MVC. In all of the MVC post-redirect-get pattern samples, I have seen three different action methods for the post-redirect-get process, each having different names. Is this really required? For Eg:(Does the code shown below, follows Post-Redirect-Get pattern?) public class SalaryTransferController : Controller { // // GET: /SalaryTransfer/ [HttpGet] public ActionResult Index(int id) { SalaryTransferIndexViewModel vm = new SalaryTransferIndexViewModel(id) { SelectedDivision = DivisionEnum.Contracting }; //Do some processing here return View(vm); } // // POST: /SalaryTransfer/ [HttpPost] public ActionResult Index(SalaryTransferIndexViewModel vm) { bool validationsuccess = false; //validate if (validationsuccess) return RedirectToAction("Index", new {id=1234 }); else return View(vm); } } Thank you for your responses.

  • asp.net-mvc feature - one css file per (view / master-page / user-control)

    - by Mendy
    I'm trying to implement the following feature: I want just one css file to be attached for any page that I rendered. For example take StackOverflow site. For the questions page, we will have questions.css file. so.com/questions ---> questions.css so.com/question/1234/title ---> question.css so.com/about ---> about.css so.com/faq ---> faq.css Now, I know that this css files share code in common, because they may have the same MasterPage(s) / UserControls. So, the solution need to take into account MasterPages, views and usercontrols as well. So, what will be the right solution for this kind of problem? I'm thinking about one solution, I'll put is as an answer, but maybe you have a better solution for this?
