  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!

  • Do Websites need Local Databases Anymore?

    - by viatropos
    If there's a better place to ask this, please let me know. Every time I build a new website/blog/shopping-cart/etc., I keep trying to do the following: Extract out common functionality into reusable code (Rubygems and jQuery plugins mostly) If possible, convert that gem into a small service so I never have to deal with a database for the objects involved (by service, I mean something lean and mean, usually built with the Sinatra Web Framework with a few core models). My assumption is, if I can remove dependencies on local databases, that will make it easier and more scalable in the long run (scalable in terms of reusability and manageability, not necessarily database/performance). I'm not sure if that's a good or bad assumption yet. What do you think? I've made this assumption because of the following reason: Most serious database/model functionality has been built on the internet somewhere. Just to name a few: Social Network API: Facebook Messaging API: Twitter Mailing API: Google Event API: Eventbrite Shopping API: Shopify Comment API: Disqus Form API: Wufoo Image API: Picasa Video API: Youtube ... Each of those things are fairly complicated to build from scratch and to make as optimized, simple, and easy to use as those companies have made them. So if I build an app that shows pictures (picasa) on an Event page (eventbrite), and you can see who joined the event (facebook events), and send them emails (google apps api), and have them fill out monthly surveys (wufoo), and watch a video when they're done (youtube), all integrated into a custom, easy to use website, and I can do that without ever creating a local database, is that a good thing? I ask because there's two things missing from the puzzle that keep forcing me to create that local database: Post API RESTful/Pretty Url API While there's plenty of Blogging systems and APIs for them, there is no one place where you can just write content and have it part of some massive thing. For every app, I have to use code for creating pretty/restful urls, and that saves posts. But it seems like that should be a service! Question is, is that what the website is? ...That place to integrate the worlds services for my specific cause... and, sigh, to store posts that only my site has access to. Will everyone always need "their own blog"? Why not just have a profile and write lots of content on an established platform like StackOverflow or Facebook? ... That way I can write apps entirely without a database and know that I'm doing it right. Note: Of course at some point you'd need a database, if you were doing something unique or new. But for the case where you're just rewiring information or creating things like videos, events, and products, is it really necessary anymore??

  • Best compiled language for Mac OS X and Linux compatibility

    - by corydoras
    We need to write some software that will compile and run on both an Mac OS X server and Ubuntu. We would love to use Objective-C with all of its Cocoa goodness, however the GNUstep implementations of the parts we are using are broken (in the latest Ubuntu package anyway.) In light of this should we use C++ (I would really rather not), C or something else that we have not thought of? It is a server/back-end process that is very resource intensive, Java and other interpreted versions of this software perform much worse than the Objective-C proof of concept we have written, hence we now wish to re-write in a "compiled[1]" language. (NB: Some people might consider this subjective, however at the end of the day we do need to get a job done, there has to be a reasonably appropriate correct answer here). [1] Compiled to native CPU instructions, not compiled into "byte codes" that then have to be run by an interpreter.

  • Is SQL used by PDO database independent?

    - by Pheter
    Different databases have slight variations in their implementations of SQL. Does PDO handle this? If I write an SQL query that I use with PDO to access a MySQL database, and later tell PDO to start using a different type of database, will the query stop working? Or will PDO 'convert' the query so that it continues to work? If PDO does not do this, are there any PHP libraries that allow me to write SQL according to a particular syntax, and then the library will handle converting the SQL so that it will run on different databases?

  • Is ruby ||= intelligent?

    - by brad
    I have a question regarding the ||= statement in ruby and this is of particular interest to me as I'm using it to write to memcache. What I'm wondering is, does ||= check the receiver first to see if it's set before calling that setter, or is it literally an alias to x = x || y This wouldn't really matter in the case of a normal variable but using something like: CACHE[:some_key] ||= "Some String" could possibly do a memcache write which is more expensive than a simple variable set. I couldn't find anything about ||= in the ruby api oddly enough so I haven't been able to answer this myself. Of course I know that: CACHE[:some_key] = "Some String" if CACHE[:some_key].nil? would achieve this, I'm just looking for the most terse syntax.

  • Autocompletion in Eclipse for Roo project

    - by niklassaers
    Hi guys, I've got a Roo project where I've made a couple of entities, and when I load up the project in Eclipse it loads up fine, but if I i.e. make an instance MyEntity entity and then write entity. I don't get any of my properties (i.e. getMyField) in the autocompletion list. If I write entity.getMyField() it compiles fine, that is taken care of by the aspects. How do I enable autocompletion for functions generated by the aspects? Cheers Nik

  • Simple bad merge scenario in mercurial

    - by user281180
    I have created a repository AAA and another BBB. In AAA I have created a file A with the values a1, a2, a3 and commit In BBB I have created a file B with the values b1, b2, b3, commit and export a bundle. I add the bundle in AAA and merge. I make a change in B, and write b33 in AAA and another change in B and write b23 in BBB. and commit both. I create bundle of BBB and add the bundle in AAA. I do a merge. Now I decide to revert to the revert to step 2. I no more want to have the merge of 4. changes done in B as they were bad merges. Now I want to add the bundle of 3 but I can see that it can`t see any changes anymore. Why? How can I do the merge once more?

  • Latex: stretchable curly braces outside math

    - by basweber
    Hi, I am producing some latex beamer slides (but I think it is not a beamer specific question per se). I have the following: \begin{itemize} \item Issue1 \item Issue2 \item Issue3 \end{itemize} Now, I want to have a right curly brace (i.e. '}') behind the items spreading over issue1 and issue2. And of course I want to write something behind that curly brace. In a perfect world I would write something like: \begin{itemize} \left . \item Issue1 \item Issue2 \right \} One and Two are cool \item Issue3 \end{itemize} This does not work because I am not in a math environment and I can not put the whole snippet inside a math environment because itemize would not work in that case. Is there a clean solution or a hack to produce my desired result? Regards, Bastian.

  • How to Use .NET Assembly from Legacy SQL Server 2000 DTS

    - by shyneman
    Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

  • OpenCV to use in memory buffers or file pointers

    - by The Unknown
    The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments. For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk. Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory. I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks! My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.

  • A web framework where AJAX was not an after thought

    - by Pirate for Profit
    AJAX is a pain in the ass because it essentially means you'll have to write two sets of similarish code: one for browsers with JavaScript enabled and those without. Not only this, but you have to connect JavaScript events to hook into your models and display the results. And if all that weren't bad enough, you need to send an address change with the request, otherwise the user won't be able to "click back" correctly (if confused look at what happens to the address bar when you click links in GMail). We're searching for something that had the foresight and design goals with all these concerns in mind. Performance and security are also obvious major concerns. We love config-based systems as well, where you don't have to write a lot of code you just drop it into an easily read config format. It's like asking for the holy grail right?

  • How do you read data from a ADODB stream in ASP as byte values?

    - by user89691
    I have an ASP routine that gets a binary file's contents and writes it to a stream. The intention is to read it from the stream and process it st the server. So I have: ResponseBody = SomeRequest (SomeURL) ; var BinaryInputStream = Server.CreateObject ("ADODB.Stream") ; BinaryInputStream.Type = 1 ; // binary BinaryInputStream.Open ; BinaryInputStream.Write (ResponseBody) ; BinaryInputStream.Position = 0 ; var DataByte = BinaryInputStream.Read (1) ; Response.Write (typeof (DataByte)) ; // displays "unknown" How do I get the byte value of the byte I have just read from the stream? Asc () and byte () don't work (JScript) TIA

  • What is a simple way to combine two Emacs major modes, or to change an existing mode?

    - by Winston C. Yang
    In Emacs, I'm working with a file that is a hybrid of two languages. Question 1: Is there a simple way to write a major mode file that combines two major modes? Details: The language is called "brew" (not the "BREW" of "Binary Runtime Environment for Wireless"). brew is made up of the languages R and Latex, whose modes are R-mode and latex-mode. The R code appears between the tags <% and %. Everything else is Latex. How can I write a brew-mode.el file? (Or is one already available?) One idea, which I got from this posting, is to use Latex mode, and treat the code of the form <% ... % as a comment. Question 2: How do you change the .emacs file or the latex.el file to have Latex mode treat code of the form <% ... % as a comment?

But it doesn't appear in SLOT parenthesis to write app method ? is it related with & character in front of app ?

  • A reasonable way to add attributes to an xml root element.

    - by DrLazer
    The function "WriteStartElement" does not return anything. I find this a little bizzare. So up until now I have been doing it like this. XmlDocument xmlDoc = new XmlDocument(); XmlTextWriter xmlWriter = new XmlTextWriter(m_targetFilePath, System.Text.Encoding.UTF8); xmlWriter.Formatting = Formatting.Indented; xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'"); xmlWriter.WriteStartElement("client"); xmlWriter.Close(); xmlDoc.Load(m_targetFilePath); XmlElement root = xmlDoc.DocumentElement; Saving the doc, then reloading it to get hold of the start element so i can write attributes to it. Does anybody know the correct way of doing this because I'm pretty sure what I'm doing isn't right. I tried to use xmlWriter.AppendChild() but it doesnt seem to write out anything. :(

  • Strange results - I obtain same value for all keys

    - by Pietro Luciani
    I have a problem with mapreduce. Giving as input a list of song ("Songname"#"UserID"#"boolean") i must have as result a song list in which is specified how many time different useres listen them... so a output ("Songname","timelistening"). I used hashtable to allow only one couple . With short files it works well but when I put as input a list about 1000000 of records it returns me the same value (20) for all records. This is my mapper: public static class CanzoniMapper extends Mapper<Object, Text, Text, IntWritable>{ private IntWritable userID = new IntWritable(0); private Text song = new Text(); public void map(Object key, Text value, Context context) throws IOException, InterruptedException { /*StringTokenizer itr = new StringTokenizer(value.toString()); while (itr.hasMoreTokens()) { word.set(itr.nextToken()); context.write(word, one); }*/ String[] caratteri = value.toString().split("#"); if(caratteri[2].equals("1")){ song.set(caratteri[0]); userID.set(Integer.parseInt(caratteri[1])); context.write(song,userID); } } } This is my reducer: public static class CanzoniReducer extends Reducer<Text,IntWritable,Text,IntWritable> { private IntWritable result = new IntWritable(); public void reduce(Text key, Iterable<IntWritable> values, Context context) throws IOException, InterruptedException { Hashtable<IntWritable,Text> doppioni = new Hashtable<IntWritable,Text>(); for (IntWritable val : values) { doppioni.put(val,key); } result.set(doppioni.size()); //doppioni.clear(); context.write(key,result); } } and main: Configuration conf = new Configuration(); Job job = new Job(conf, "word count"); job.setJarByClass(Canzoni.class); job.setMapperClass(CanzoniMapper.class); //job.setCombinerClass(CanzoniReducer.class); //job.setNumReduceTasks(2); job.setReducerClass(CanzoniReducer.class); job.setOutputKeyClass(Text.class); job.setOutputValueClass(IntWritable.class); FileInputFormat.addInputPath(job, new Path(args[0])); FileOutputFormat.setOutputPath(job, new Path(args[1])); System.exit(job.waitForCompletion(true) ? 0 : 1); Any idea???

  • Run shell script using fabric and piping script text to shell's stdin

    - by Peter Lyons
    Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

  • Database EAV model, record listing as per search

    - by Shyam Sunder Verma
    I am building a dynamic application. I have three tables : ( EAV model style) 1: Items ( ItemId, ItemName) 2: Fields (FieldId, FieldName) 3: Field Values ( ItemID, FieldId, Value) Can you tell me how to write SINGLE query to get starting 20 records from ALL items where FieldId=4 is equal to TRUE. Expected Result : Columns = ItemID | Name | Field1 | Field2 | Field3 Each Row= ItemId | ItemName| Value1 | Value2 | Value3 Important concerns : 1: Number of fields per item are not known 2: I need one to write ONE query. 3: Query will be running on 100K records, so performance is concern. 4: I am using MySQL 5.0, so need solution for MYSQL Should I denormalize the tables if above query is not possible at all ? Any advice ?

  • Decimal data Type Display scale part as zero

    - by Wael Dalloul
    I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

  • C# "Could not find a part of the path" - Creating Local File

    - by Pyronaut
    I am trying to write to a folder that is located on my C:\ drive. I keep getting the error of : Could not find a part of the path .. etc My filepath looks basically like this : C:\WebRoot\ManagedFiles\folder\thumbs\5c27a312-343e-4bdf-b294-0d599330c42d\Image\lighthouse.jpg And I am writing to it like so : using (MemoryStream memoryStream = new MemoryStream()) { thumbImage.Save(memoryStream, ImageFormat.Jpeg); using (FileStream diskCacheStream = new FileStream(cachePath, FileMode.CreateNew)) { memoryStream.WriteTo(diskCacheStream); } memoryStream.WriteTo(context.Response.OutputStream); } Don't worry too much about the memory stream. It is just outputting it (After I save it). Since I am creating a file, I am a bit perplexed as to why it cannot find the file (Shouldn't it just write to where I tell it to, regardless?). The strange thing is, It has no issue when I'm testing it above using File.Exists. Obviously that is returning false, But it means that atleast my Filepath is semi legit. Any help is much appreciated.

  • How to handle the browsers who don't support HTML5/CSS3

    - by Sheikh Aman
    Hi, I have been looking into HTML5 and CSS3 and have been liking it quite a lot. Got around the modernizr API, but am stuck at one point, and that leads to further confusions: How will I write a code that caters to the situation of non-compatibility between browsers ? This leads to the following confusions: if I write the doctype as <!DOCTYPE HTML> and my page is accessed in IE6, then ho IE6 will handle the page? If I try to include <video> tag and the page is again accessed by IE6/IE7IE8 (which don't support this tag), Then how am I supposed to be rolling back to flash for them? Should I use some JS to show/hide the content appropriately? I would love to hear some thoughts of you guys. If needed, please mark this post as a community wiki. Thanks!

  • Find all clauses related to an atom

    - by Luc Touraille
    This is probably a very silly question (I just started learning Prolog a few hours ago), but is it possible to find all the clauses related to an atom? For example, assuming the following knowledge base: cat(tom). animal(X) :- cat(X). , is there a way to obtain every possible information about tom (or at least all the facts that are explicitly stated in the base)? I understand that a query like this is not possible: ?- Pred(tom). so I thought I could write a rule that would deduce the correct information: meta(Object, Predicate) :- Goal =.. [Predicate, Object], call(Goal). so that I could write queries such as ?- meta(tom, Predicate). but this does not work because arguments to call are not sufficiently instantiated. So basically my question is: is this at all possible, or is Prolog not design to provide this kind of information? And if it is not possible, why?
