  • preg_replace function to append a string to all the hyperlinks of a page

    - by KoolKabin
    hi guys, i want to append my own value to all hyperlinks in a page... e.g if there are links: <a href="abc.htm?val=1">abc 1</a> <br/> <a href="abc.htm?val=2">abc 1</a> <br/> <a href="abc.htm?val=3">abc 1</a> <br/> <a href="abc.htm?val=4">abc 1</a> <br/> I want to add next var like "type=int" to all hyperlinks output should be: <a href="abc.htm?val=1&type=int">abc 1</a> <br/> <a href="abc.htm?val=2&type=int">abc 1</a> <br/> <a href="abc.htm?val=3&type=int">abc 1</a> <br/> <a href="abc.htm?val=4&type=int">abc 1</a> <br/> I hope it can be done quite easily with preg_replace function

  • Can a Generic Method handle both Reference and Nullable Value types?

    - by Adam Lassek
    I have a series of Extension methods to help with null-checking on IDataRecord objects, which I'm currently implementing like this: public static int? GetNullableInt32(this IDataRecord dr, int ordinal) { int? nullInt = null; return dr.IsDBNull(ordinal) ? nullInt : dr.GetInt32(ordinal); } public static int? GetNullableInt32(this IDataRecord dr, string fieldname) { int ordinal = dr.GetOrdinal(fieldname); return dr.GetNullableInt32(ordinal); } and so on, for each type I need to deal with. I'd like to reimplement these as a generic method, partly to reduce redundancy and partly to learn how to write generic methods in general. I've written this: public static Nullable<T> GetNullable<T>(this IDataRecord dr, int ordinal) { Nullable<T> nullValue = null; return dr.IsDBNull(ordinal) ? nullValue : (Nullable<T>) dr.GetValue(ordinal); } which works as long as T is a value type, but if T is a reference type it won't. This method would need to return either a Nullable type if T is a value type, and default(T) otherwise. How would I implement this behavior?

  • Hiding an internal interface in a "friend" assembly

    - by dmo
    I have two assemblies: A and B. A has InternalsVisibleTo set for B. I would like to make calls from A to get information that can only be known by a type defined in B in a way that keeps things internal. I can do this using an internal interface defined in A and implemented explicitly in B. Assembly A internal interface IHasData { Data GetData(); } class ClassA { DoSomething(IHasData); } Assembly B public abstract class ClassB : IHasData { Data IHasData.GetData() { /** do something internal **/ } } The trouble comes when someone references assembly B and derives from ClassB - they get the error: "The type 'AssemblyA.IHasData' is defined in an assembly that is not referenced" even though that type should be invisible to them. If I look at the public type definition I see what I expect - ClassB with no interfaces implemented. Why do I get this error? All of the implementation is in assembly B. I could use IHasData internally in ClassB and that wouldn't require assembly A to be referenced. Can someone help me understand what is going on?

  • How to binding to bit datatype in SQL to Booleans/CheckBoxes in ASP.NET MVC 2 with DataAnnotations

    - by nvtthang
    I've got problem with binding data type boolean to checkbox in MVC 2 data annotations Here's my code sample: label> Is Hot </label> <%=Html.CheckBoxFor(model => model.isHot, new {@class="input" })%> It always raise this error message below at (model=model.isHot). Cannot convert lambda expression to delegate type 'System.Func<Framework.Models.customer,bool>' because some of the return types in the block are not implicitly convertible to the delegate return type Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Please suggest me how can I solve this problem? Thanks in advance.

  • Looking for design help

    - by jess
    I have this scenario in most of the WindowsForms having grids I have a sequence of code which is similar - AddNewRow(in grid),CreateNewEntity,notifyUser,few other steps Now, I want to use a template kind of pattern.But,my issue is with CreateEntity method since sometimes it is passed a parameter which is different depending on the type of object being created.Should I make createentity accept an "object" type,and cast when the parameter is to be used.What other way can I tackle this design issue? Also,CreateEntity returns the object being created.

  • Location of Embedly (JQuery-Preview) Results

    - by user749798
    Embedly/Jquery-Preview has been fantastic. However, I'm trying to change the location of the preview result, and having trouble. Right now, the result appears right below the input field...but I'd rather have it in a separate part of the page. Is there a way to do this? I've tried changing the location of the selector and loading divs, but that hasn't helped. It seems to ignore those divs and put it right below the submit button. Below is my code: <form accept-charset="UTF-8" action="private" class="new_comment" data-remote="true" id="new_comment" method="post"> <input class="photo_comm" id="comment_comment" name="comment[comment]" placeholder="add a comment or link..." size="30" type="text" /><span type="text" id="counter">1000</span> <input class="btn btn-primary btn-mini" data-disable-with="Submitting..." name="commit" type="submit" value="Post" /> </form> <!-- Placeholder that tells Preview where to put the loading icon--> <div class="loading"> <img src='http://embedly.github.com/jquery-preview/images/loading-rectangle.gif'> </div> <!-- Placeholder that tells Preview where to put the selector--> <div class="selector"></div> $('#comment_comment').preview({ key:'60f1dcdf3258476794784148a6eb65e7', // Sign up for a key: http://embed.ly/pricing selector : {type:'rich'}, preview : { submit : function(e, data){ e.preventDefault(); $.ajax({ dataType: 'script', url: this.form.attr('action'), type: 'POST', data: data }); }, }, autoplay : 0, maxwidth : 400, display : {display : 'rich'} });

  • Google App Engine: lose CSS on deployment?

    - by Rosarch
    I have a Google App Engine app that works fine on the dev server. However, when I upload it, the CSS is gone. The scripts are still there, however. From app.yaml: - url: /scripts static_dir: Static/Scripts - url: /styles static_dir: Static/styles From the base template: <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <script type="text/javascript" src="./scripts/JQuery.js"></script> <script type="text/javascript" src="./scripts/sprintf.js"></script> <link rel="stylesheet" href="./styles/style.css" type="text/css" media="screen" /> </head> What could be causing this? Am I doing something wrong?

  • What's the purpose of the maxPostSize for Tomcat's HTTP Connector?

    - by Bytecode Ninja
    According to Tomcat docs: The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes). But what's "the container FORM URL parameter parsing"? Any ideas what is the purpose of "maxPostSize"? Thanks in advance.

  • Rails routes matching query parameters

    - by Harry Wood
    Rails routes are great for matching RESTful style '/' separated bits of a URL, but can I match query parameters in a map.connect config. I want different controllers/actions to be invoked depending on the presence of a parameter after the '?'. I was trying something like this... map.connect "api/my/path?apple=:applecode", :controller = 'apples_controller', :action = 'my_action' map.connect "api/my/path?banana=:bananacode", :controller = 'bananas_controller', :action = 'my_action' For routing purposes I don't care about the value of the parameter, as long as it is available to the controller in the 'params' hash

  • Object validator - is this good design?

    - by neo2862
    I'm working on a project where the API methods I write have to return different "views" of domain objects, like this: namespace View.Product { public class SearchResult : View { public string Name { get; set; } public decimal Price { get; set; } } public class Profile : View { public string Name { get; set; } public decimal Price { get; set; } [UseValidationRuleset("FreeText")] public string Description { get; set; } [SuppressValidation] public string Comment { get; set; } } } These are also the arguments of setter methods in the API which have to be validated before storing them in the DB. I wrote an object validator that lets the user define validation rulesets in an XML file and checks if an object conforms to those rules: [Validatable] public class View { [SuppressValidation] public ValidationError[] ValidationErrors { get { return Validator.Validate(this); } } } public static class Validator { private static Dictionary<string, Ruleset> Rulesets; static Validator() { // read rulesets from xml } public static ValidationError[] Validate(object obj) { // check if obj is decorated with ValidatableAttribute // if not, return an empty array (successful validation) // iterate over the properties of obj // - if the property is decorated with SuppressValidationAttribute, // continue // - if it is decorated with UseValidationRulesetAttribute, // use the ruleset specified to call // Validate(object value, string rulesetName, string FieldName) // - otherwise, get the name of the property using reflection and // use that as the ruleset name } private static List<ValidationError> Validate(object obj, string fieldName, string rulesetName) { // check if the ruleset exists, if not, throw exception // call the ruleset's Validate method and return the results } } public class Ruleset { public Type Type { get; set; } public Rule[] Rules { get; set; } public List<ValidationError> Validate(object property, string propertyName) { // check if property is of type Type // if not, throw exception // iterate over the Rules and call their Validate methods // return a list of their return values } } public abstract class Rule { public Type Type { get; protected set; } public abstract ValidationError Validate(object value, string propertyName); } public class StringRegexRule : Rule { public string Regex { get; set; } public StringRegexRule() { Type = typeof(string); } public override ValidationError Validate(object value, string propertyName) { // see if Regex matches value and return // null or a ValidationError } } Phew... Thanks for reading all of this. I've already implemented it and it works nicely, and I'm planning to extend it to validate the contents of IEnumerable fields and other fields that are Validatable. What I'm particularly concerned about is that if no ruleset is specified, the validator tries to use the name of the property as the ruleset name. (If you don't want that behavior, you can use [SuppressValidation].) This makes the code much less cluttered (no need to use [UseValidationRuleset("something")] on every single property) but it somehow doesn't feel right. I can't decide if it's awful or awesome. What do you think? Any suggestions on the other parts of this design are welcome too. I'm not very experienced and I'm grateful for any help. Also, is "Validatable" a good name? To me, it sounds pretty weird but I'm not a native English speaker.

  • Django form and i18n

    - by madewulf
    I have forms that I want to display in different languages : I used the label parameter to set a parameter, and used ugettext() on the labels : agreed_tos = forms.BooleanField(label=ugettext('I agree to the terms of service and to the privacy policy.')) But when I am rendering the form in my template, using {{form.as_p}} The labels are not translated. Does somebody have a solution for this problem ?

  • Mustache vs other engines. Maybe I should use another template engine?

    - by marcioAlmada
    I'm passing an object to mustache and this object has a method with one parameter. Is something like this possible with Mustache and PHP? {{object.method(parameter)}} If it gets too laborious to achieve this with Mustache, what template engine would you recommend? Remember I need to pass parameters to object methods while in the view context (like we do with helpers). The nearest as possible to mustache syntax is welcome.

  • Generics in custom configuration sections

    - by Jonn
    I tried making a custom configuration class that went on like this: WatcherServiceInfoSection<TWatcherServiceDetailElement> where TWatcherServiceDetailElement is a ConfigurationElement inside it. Now when I call the type in the ConfigSections area of AppConfig I get the error: An error occurred creating the configuration section handler for WatcherServiceInfo: Could not load type 'Library.Common.Utilities.ConfigurationHandler.WatcherServiceInfoSection<ASNDPService.Configuration.WatcherServiceDetailElement>' from assembly Is what I'm doing possible? Can I have generic types in the type attribute for a custom section element? EDIT Additionally, how about ConfigurationElementCollection objects? Like in the above example, how could I do a [ConfigurationProperty("WatcherServiceDetails", IsRequired = true, IsDefaultCollection = true)] [ConfigurationCollection(typeof(TWatcherServiceDetailElement), AddItemName = "WatcherServiceDetail")] public WatcherServiceDetailCollection<TWatcherServiceDetailElement> WatcherServiceDetails I'm aware that type parameters aren't allowed for attributes and that's what I want to know how to do.

  • Hibernate multi column discriminator

    - by shikarishambu
    I have a single lookup table that manages all lookups - legacy and new lookup table structure is context,name, code, value context is either legacy or new name is the name of the lookup - state, status etc...for example code is the code and value is the value associated with the code Is there a way to specify multiple columns as discriminators so that I can get all legacy state code/values or all new status code/values. Is there a different way to do this if discriminators cannot do it? <class name="com.company.domain.Lookup"> <id name="Id" column="id" type="big_integer"> <generator class="org.hibernate.id.TableHiLoGenerator" /> </id> <discriminator column="context" insert="false" /> <property name="code" type="string"/> <property name="value" type="string"/> <property name="desc" type="string"/> <subclass name="com.company.domain.LegacyLookup" discriminator-value="legacy">

  • jQuery Form plugin - no data from file upload?

    - by pojo
    I've been struggling a bit with the jQuery Form plugin. I want to create a file upload form that posts the data (JSON, from the chosen file) into a REST service exposed by a servlet. The URL for the POST is calculated from what the user chooses in a SELECT dropdown. When the upload is complete, I want to notify the user immediately, AJAX-style. The problem is that the POST header has a Content-Length of 0 and contains no data. I would appreciate any help! <html> <head> <script type="text/javascript" src="js/jquery-1.4.2.min.js">/* ppp */</script> <script type="text/javascript" src="js/jquery.form.js">/* ppp */</script> <script type="text/javascript"> function cb_beforesubmit (arr, $form, options) { // This should override the form's action attribute options.url = "/rest/services/" + $('#selectedaction')[0].value; return true; } function cb_success (rt, st, xhr, wf) { $('#response').html(rt + '<br>' + st + '<br>' + xhr); } $(document).ready(function () { var options = { beforeSubmit: cb_beforesubmit, success: cb_success, dataType: 'json', contentType: 'application/json', method: 'POST', }; $('#myform').ajaxForm(options); $.getJSON('/rest/services', function (data, ts) { for (var property in data) { if (typeof property == 'string') { $('#selectedaction').append('<option>' + property + '</option>'); } } }); }); </script> </head> <body> <form id="myform" action="/rest/services/foo1" method="POST" enctype="multipart/form-data"> <!-- The form does not seem to submit at all if I don't set action to a default value? !--> <select id="selectedaction"> <script type="text/javascript"> </script> </select> <input type="file" value="Choose"/> <input type="submit" value="Submit" /> </form> <div id="response"> </div> </body> </html>
