  • Using DataTypeAttribute to validate a date

    - by Andy Evans
    I'm having some difficulty understanding how to validate a date (DOB) using MVC2. What I want to do is 1. Is the date entered a valid date and, 2. Is the date at lease 13 years in the past. For example, to validate an email I use the following code: [Required(ErrorMessage = "Email address is required.")] [StringLength(320, ErrorMessage = "Email must be less than 320 characters.")] [Email(ErrorMessage = "This email address is invalid.")] public string email { get; set; } To validate the email I use: public class EmailAttribute : RegularExpressionAttribute { public EmailAttribute() : base("insert long regex expression here") { } } Any assistance would be greatly appreciated, thanks!

  • Why is one Func valid and the other (almost identical) not.

    - by runrunraygun
    private static Dictionary<Type, Func<string, object>> _parseActions = new Dictionary<Type, Func<string, object>> { { typeof(bool), value => {Convert.ToBoolean(value) ;}} }; The above gives an error Error 14 Not all code paths return a value in lambda expression of type 'System.Func<string,object>' However this below is ok. private static Dictionary<Type, Func<string, object>> _parseActions = new Dictionary<Type, Func<string, object>> { { typeof(bool), value => Convert.ToBoolean(value) } }; I don't understand the difference between the two. I thought the extra braces in example1 are to allow us to use multiple lines in the anon function so why have they affected the meaning of the code?

  • Will WF 4.0 make me Obsolete

    - by codemnky
    I saw a post on Oslo about making us obsolete. I just happened to listen to the latest Deep Fried Episode with Brian Noyes. They were talking about SharePoint and Windows Workflow and how the "dream" of Windows Workflow is to let mere Business Analyst Drag and Drop their way to a functioning service. I am a newbie dotnet developer, and afraid that by the time I get to Consulting "Level" my skills would be obsolete. Should I abandon learning basic skills and just learn how to work with Frameworks and Packaged applications such as SAP, SharePoint, BizTalk. Am I wasting time trying to learn Expression Trees and Func of T's?

  • How to extract data from a text file

    - by šljaker
    I need to parse some large text file and extract Display name and area code only if it matches the following pattern: Line starts with display name (any number of words) Followed by 6 digits (can contain spaces) Followed by #text tag e.g. John doe 123 456 #text some text Display name: John doe Area code: 123 456 Test 123456 #text Display name: Test Area code: 123456 Test 123 #test Invalid, area code contains only 3 digits Test 123456 #test1 Invalid, contains invalid tag Test 123g45 #test Invalid, area code contains letters etc. I know how to open the text file and read it line by line, but having trouble with writing the regular expression. Any help would be greatly appreciated! edit: I have tried this: private static void Main(string[] args) { string text = "John Doe 123 45 #text Lorem ipsum dolor :)"; string pattern = @"(\w+)*([0-9]{2,5}).([0-9]{2,5}).#text"; Match match = Regex.Match(text, pattern, RegexOptions.IgnoreCase); if (match.Success) { string key = match.Groups[0].Value; Console.WriteLine(key); } }

  • How do I use global resources in WPF?

    - by Banford
    I have a WPF application which I would like to use some static resources in. I have created a Resource Library XAML file which contains a resource. I have also added a string into the Resources of the project through the Properties panel. I assumed I could just use these resources with the binding expression: {StaticResource ResourceName} But visual studio is telling me the resources are not found. Do I have to include some form of reference in my XAML? The examples I have seen only include resources locally such as: <Window.Resources>, <Page.Resources> etc I don't want to include the resources locally because I want them to be available to multiple parts of the application.

  • How would you parse the location text from Twitter to get the latitude/longitude in Objective-C?

    - by Brennan
    The location text from Twitter could be just about anything. Sometimes Twitter clients set the location with the user's latitude and longitude in the following format. "\U00dcT: 43.05948,-87.908409" Since there is no built-in support for Regular Expressions in Objective-C I am considering using the NSString functions like rangeOfString to pull the float values out of this string. For my current purpose I know the values with start with 43 and 87 so I can key off those values this time but I would prefer to do better than that. What would you do to parse the latitude/longitude from this string?

  • How to add debug assemblies to my Silverlight 2 application?

    - by Steve Wortham
    So I know now that the debug assemblies have been intentionally left out of the Silverlight runtime to save space. For that reason I get good detailed error messages on my local machine that has the Silverlight SDK on it, but I don't on a computer with the runtime only. I get the ubiquitous, "Debugging resource strings are unavailable." Unfortunately my requirements are a bit unique. I need to include the debug assembly (not sure which one yet) that will give me details of a regular expression error. And so essentially I want to include the dll in the xap if I can. The problem is that I can't seem to do this. I've tried adding the debug dll's as references and setting them to "copy local." And I've tried adding them into the project as content. But in fact, with either method the xap hardly grows in size and the error message doesn't change. Any ideas?

  • Hibernate criteria with projection not performing query for @OneToMany mapping

    - by Josh
    I have a domain object, Expense, that has a field called initialFields. It's annotated as so: @OneToMany(fetch = FetchType.EAGER, cascade = { CascadeType.ALL }, orphanRemoval = true) @JoinTable(blah blah) private final List<Field> initialFields; Now I'm trying to use Projections in order to only pull certain fields for performance reasons, but when doing so the initialFields field is always null. It's the only OneToMany field and the only field I am trying to retrieve with the projection that is behaving this way. If I use a regular HQL query initialFields is populated appropriately, but of course I can't limit the fields. Anyone ever seen anything like this?

  • PostgreSQL like + Hibernate problem

    - by Marat_Galiev
    Hi all. I want to do search in PostgreSQL for INTEGER based columns. if (!sSearch.isEmpty()) { sSearch = sSearch.replaceAll("[^a-zA-Z0-9]", "_").toLowerCase(); String[] search = sSearch.split(" "); sWhere = " "; for (NewsColumns column : NewsColumns.values()) { for (String s : search) { sWhere += "lower(" + column + "::TEXT) LIKE '%" + s + "%' OR "; } } sWhere = sWhere.substring(0,sWhere.length()-3); } Ok, I want to convert INT value to String before search, with '::TEXT' expression. But after executing I'm getting: org.hibernate.QueryException: Not all named parameters have been set: [:TEXT] [select * from news WHERE lower(ID::TEXT) LIKE '%5%' Exception. Looks like hibernate parse my convert exp as parameter. Any help is appreciated. Thanks.

  • php regex replace slashes and spaces and hyphens

    - by Muhammad Shahzad
    I have fews combinations of strings that I need to bring in to one pattern, that is multiple spaces should be removed, double hyphens should be replaced with single hypen, and single space should be replaced with single hyphen. I have already tried this expression. $output = preg_replace( "/[^[:space:]a-z0-9]/e", "", $output ); $output = trim( $output ); $output = preg_replace( '/\s+/', '-', $output ); But this fails in few combinations. I need help in making all of these combinations to work perfectly: steel-black steel- black steel black I should also remove any of these as well "\r\n\t".

  • Conditionally set a column to its default value in Postgres

    - by Evgeny
    I've got a PostgreSQL 8.4 table with an auto-incrementing, but nullable, integer column. I want to update some column values and, if this column is NULL then set it to its default value (which would be an integer auto-generated from a sequence), but I want to return its value in either case. So I want something like this: UPDATE mytable SET incident_id = COALESCE(incident_id, DEFAULT), other = 'somethingelse' WHERE ... RETURNING incident_id Unfortunately, this doesn't work - it seems that DEFAULT is special and cannot be part of an expression. What's the best way to do this?

  • What's the fastest way to strip and replace a document of high unicode characters using Python?

    - by Rhubarb
    I am looking to replace from a large document all high unicode characters, such as accented Es, left and right quotes, etc., with "normal" counterparts in the low range, such as a regular 'E', and straight quotes. I need to perform this on a very large document rather often. I see an example of this in what I think might be perl here: http://www.designmeme.com/mtplugins/lowdown.txt Is there a fast way of doing this in Python without using s.replace(...).replace(...).replace(...)...? I've tried this on just a few characters to replace and the document stripping became really slow.

  • Using sizeof operator on a typedef-ed struct

    - by sskanitk
    This might be something too obvious. However, I couldn't find the specific answer though many stackoverflow threads talk about different aspects of this. typedef struct _tmp { unsigned int a; unsigned int b; } tmp; int main() { int c=10; if (c <= sizeof tmp) { printf("less\n"); } else { printf("more\n"); } return 0; } I compile this prog as - g++ -lstdc++ a.cpp I get an error - expected primary-expression before ‘)’ token I think I am missing something very obvious and straightforward. But can't seem to pinpoint it :-/ Thanks!

  • Get jQuery Error if PHP Breaks

    I have a PHP script that breaks if a variable is not populated and it isn't added to the database, but jQuery handles this as a success and I get this error: TypeError: Result of expression 'data' [null] is not an object. Here's the jQuery script: $.ajax({ type: "POST", url: "/clase/do-add", data: $("#adauga").serialize(), dataType: "json", error: function (xhr, textStatus, errorThrown) { alert('Try again.'); }, success: function(data) { var dlHTML = '<dl id="' + data.id + '"> [too long] </dl>'; $('form#adauga').after(dlHTML); $('#main dl:first').hide().fadeIn(); adaugaClasaSubmit.removeAttr('disabled'); adaugaClasa.removeAttr('readonly'); adaugaClasa.val("").focus(); } });

  • C# regex: negative lookahead fails with the single line option

    - by Sylverdrag
    I am trying to figure out why a regex with negative look ahead fails when the "single line" option is turned on. Example (simplified): <source>Test 1</source> <source>Test 2</source> <target>Result 2</target> <source>Test 3</source> This: <source>(?!.*<source>)(.*?)</source>(?!\s*<target) will fail if the single line option is on, and will work if the single line option is off. For instance, this works (disables the single line option): (?-s:<source>(?!.*<source>)(.*?)</source>(?!\s*<target)) My understanding is that the single line mode simply allows the dot "." to match new lines, and I don't see why it would affect the expression above. Can anyone explain what I am missing here?

  • Dot Game and Dynamic Programming

    - by Albert Diego
    I'm trying to solve a variant of the dot game with dynamic programming. The regular dot game is played with a line of dots. Each player takes either one or two dots at their respective end of the line and the person who is left with no dots to take wins. In this version of the game, each dot has a different value. Each player takes alternate turns and takes either dot at either end of the line. I want to come up with a way to use dynamic programming to find the max amount that the first player is guaranteed to win. I'm having problems grasping my head around this and trying to write a recurrence for the solution. Any help is appreciated, thanks!

  • Can I create a collection in Scala that uses different equals/hashCode/compare implementations?

    - by Willis Blackburn
    I'm looking for as simple way to create an identity set. I just want to be able to keep track of whether or not I've "seen" a particular object while traversing a graph. I can't use a regular Set because Set uses "==" (the equals method in Scala) to compare elements. What I want is a Set that uses "eq." Is there any way to create a Set in Scala that uses some application-specified method for testing equality rather than calling equals on the set elements? I looked for some kind of "wrapEquals" method that I could override but did not find it. I know that I could use Java's IdentityHashMap, but I'm looking for something more general-purpose. Another idea I had was to just wrap each set element in another object that implements equals in terms of eq, but it's wasteful to generate tons of new objects just to get a new equals implementation. Thanks!

  • data type mismatch when comparing dates in MS-Access

    I have dates stored in an MS-Access table in the 'General Date' format. I'm trying to create a query that returns records between a specific date range (all records from March 2010) however I encounter a 'data type mismatch in critera expression' message. Here is my statement; SELECT Loan.loan_datetimeLeant, product_name, [product_artist/director], product_category, loanItem_cost FROM Loan INNER JOIN ((Product INNER JOIN Item ON Product.[product_id] = Item.[product_id]) INNER JOIN Loan_Items ON Item.[item_id] = Loan_Items.[item_id]) ON (Loan.[cust_id] = Loan_Items.[cust_id]) AND (Loan.[loan_datetimeLeant] = Loan_Items.[loan_datetimeLeant]) WHERE Loan.loan_datetimeLeant = '01/03/2010' AND Loan.loan_datetimeLeant <= '31/03/2010' ORDER BY Loan.loan_datetimeLeant ; I have tried variations on the date format (mm/dd/yyyy, dd/mm/yyyy 00:00:00)
