• How to subString a block of user generated HTML while preserving formatting?

  - by Chad

  I'd like to create the typical preview paragraph with a [read more] link. Problem is, the content that I'd like to SubString() contains text and html, written by a user with a WYSIWYG editor. Of course, I check to make sure the string is not null or empty, then SubString() it, problem is that I could end up breaking the html tags, throwing off the rendering of the entire site. The WYSIWYG editor doesn't seem to create perfectly formatted HTML, and many times seems to use <br /> tags instead of <p></p>, etc... basically, I can't rely on well-formed tags, etc. My workaround was to just strip out all HTML and substring the leftover text. This works, but loses any of the formatting that was in the HTML. What's the best method of SubString()'ing a block of non-well-formed HTML while maintaining HTML that won't break the rendering of the site?

• PHP is there a true() function?

  - by Gremo

  I'm writing a function to check all elements inside an array, returning a single boolean value. is there a true() function? function all($f, array $arr) { return empty($arr) ? false : array_reduce($arr, function($v1, $v2) use ($f) { return $f($v1) && $f($v2); }, true); } $test = array(1, 6, 2); $gte0 = function($v) { return $v >= 0; } var_dump(all($gte0, $test)); // True $test = array(true, true, false); $id = function($v) { return $v; } // <-- this is what i would avoid var_dump(all($id, $test)); // False all(true, $test); // NOT WORKING because true is not a function

• how can i get proper Uri of a particular contact in android 2.1

  - by Rishabh

  I have written an application and added 2 contacts on emulator, but i am not able to update their names on android 2.1, code is working on android 1.6 platform with the following code. ContentValues contactValues = new ContentValues(); contactValues.put(Contacts.People.NAME, firstName+" "+lastName); getContentResolver().update(UpdateContactUri, contactValues, null, null); In android 1.6 i am getting Uri for those two contacts are "content:// contacts/people/1" and "content://contacts/people/2". but in 2.1 I am getting these values are "content://contacts/people/8" and "content://contacts/people/9" and while updating its giving "java.IllegalArgumentException, Empty values" exception. When i tried to put a static Uri like "content://contacts/people/1", code was debugged sucessfully but contact was not updated. How can i resolve it, why i am not getting uri like 1.6 platform ? Thanks in advance...

• C# property definition

  - by Sunny

  For C# properties, I can do this: public class Employee{ public string Name { get; private set; } public Employee(string name){ Name = name; } } which means that the Name property can be set within the class Employee & can be read publicly. But, if I want to restrict the set to only within the constructors of the Employee class, I need to do: public class Employee{ public readonly string Name = String.Empty; public Employee(string name){ Name = name; } } But, for this case, I had to change the property to a field. Is there any reason this is not possible/allowed in C#: public class Employee{ public string Name { get; private readonly set; } public Employee(string name){ Name = name; } } IMO this will allow us to have properties which can be set only in the constructor & does not require us to change properties to fields... Thanks!

• Xcode 4: deleting items in Build Settings

  - by occulus

  In XCode 4.0 there's a newly designed Build Settings page. My problem is that I can't see how to remove a setting once I've specified it. Example: I've changed "Versioning System" to "Apple Generic" at the target level. Afterwards I realised I should set it at the project level, and so I want to delete the target level setting. However, there's no way I can see to remove the setting -- you click on it and there's two options, neither of which is the default "not specified" empty setting. Hitting the delete key on the keyboard nothing. The same goes for fields that accept text -- if I try to delete a setting by just deleting all the text set, it still shows that field in green, but with no text in it, and regards it as the presence of a setting.

• Silly Objective-C inheritance problem when using property

  - by Ben Packard

  I've been scratching my head with this for a couple of hours - I haven't used inheritance much. Here I have set up a simple Test B class that inherits from Test A, where an ivar is declared. But I get the compilation error that the variable is undeclared. This only happens when I add the property and synthesize declarations - works fine without them. TestA Header: #import <Cocoa/Cocoa.h> @interface TestA : NSObject { NSString *testString; } @end TestA Implementation is empty: #import "TestA.h" @implementation TestA @end TestB Header: #import <Cocoa/Cocoa.h> #import "TestA.h" @interface TestB : TestA { } @property NSString *testProp; @end TestB Implementation (Error - 'testString' is undeclared) #import "TestB.h" @implementation TestB @synthesize testProp; - (void)testing{ NSLog(@"test ivar is %@", testString); } @end

• How do I manage report paging in HTML?

  - by ProfK

  I have a small, custom crafted HTML report, not using any reporting engine, for various reasons. The client's layout is quite handy, as each report section fits on its own page, so I have one div for each page, with a CSS class of .page, setting A4 dimensions with margin, and a header image. Each 'page' also has a small header table just under the header image, and a section heading label. Now, some sections threaten to overflow their page, and I'm looking at ways to handle this. One clumsy approach is to include a second page for those sections that might overflow, and delete these pages before rendering if they are empty. If I do this, how can I 'tell' content on one page to overflow into the next page? The report is finished and a once off effort, so I'm not keen to convert it into a SSRS or Telerik report just to achieve this paging.

• What is wrong with this null check for data reader

  - by Phil

  c.Open() r = x.ExecuteReader If Not r("filename").IsDbnull Then imagepath = "<img src='images/'" & getimage(r("filename")) & " border='0' align='absmiddle'" End If c.Close() r.Close() I have also tried; If r("filename") Is DBNull.Value Then imagepath = String.Empty Else imagepath = "<img src='images/'" & getimage(r("filename")) & " border='0' align='absmiddle'" End If c.Close() r.Close() The error is: Invalid attempt to read when no data is present. The idea of my code is to build an img src string only when data is available. Help greatly appreciated. Thanks

• custom validation does not seem to get registered.

  - by viet pham

  Hi, Inside a tab, I have a form that is dynamically loaded via ajax. Since the name of the field is dynamic too (e.g. ), I write a custom validation method inside the "on complete" like this. However, the custom code does not get executed (bolded alert never pops up) no matter what i try. $.ajax ( { url: 'index.php?func=trainingmgr&aAction=displayAddForm', type: 'GET', dataType: 'html', complete: function(req, err) { //Append response to the tab's body $(href, '#trainingTabs').append(req.responseText); $.validator.addMethod ( 'tRequired', function(value, element) { if(value == '') { **alert('I am empty');** return true; } else return false; }, '<br>Required field' ); $('#upload' + index).click ( function() { $('#addForm' + index).validate().numberOfInvalids(); } ); } } );

• the best "Simple" CMS system suitable for .Net MVC

  - by Truegilly

  Hello, I'm developing a MVC .Net site and would like to implement a CMS system. So far I have looked at Umbraco, which looks good but the help is poor and the getting started video section is empty, and dotnetnuke, which again looks good but I get the impression its aimed at non developers, plus to has much more than I need and want. In my last job I created a basic custom CMS system that worked by simply adding values into the database, the application called the text from there. it worked fine but I don’t have the source code. what I'm after is a simple CMS system that really just controls text and images, I dont need all the fancy stuff thats in umbraco and dotnetnuke, all the design and CSS i can do myself. also as im working with MVC (which is awesome, and such a breath of fresh air compared to the web forms/telerik crap I have to put up with at work) it needs to be compatible. A simple CMS, can anyone provide any suggestion ? Truegilly

• how to debug java mail

  - by voipp

  My goal is to debug my programm, that uses java mail library(including javax.mail and com.sun.mail). So i decided first to download java mail sources and compile it with option -g.

After decompiling i receive empty directory. I downloaded jad.exe and run it , but it throwed a message : JavaClassFileParseException: Not a class file. It says it decompiles only classes, but what about jars? Is it so hard just store sources in fu** zip ???!!!!

• Immutable Dot Net strings

  - by klork

  I usually define my string variables in vb.net as Dim f_sName as string=String.Empty f_sName = "foo" Given the immutable nature of strings in .net, is there a better way to initialize strings and deal with the "Variable 'f_sName ' is used before it has been assigned a value. A null reference exception could result at runtime." warning? Also for classes that do not have constructors which accept no arguments such as System.Net.Sockets.NetworkStream, what is the best way to define and initialize a variable of that type? All comments are highly appreciated. Thanks

• How to best deal with photos passed to IFilter?

  - by sharptooth

  I'm implementing an IFilter for indexing image formats. One problem is photos - many users have tons of photos, photos are huge and loading and searching for text on them is time consuming. Yes, sometimes people use cameras instead of scanners for digitizing documents, but the potential problems IMO far outweight the possibility of encountering a document digitized with a photo camera. So my implementation will not extract text from photos at all. What should the IFilter do once it detects that a given file is a photo image - indicate an error or return empty text?

• What causes a WPF ListCollectionView that uses custom sorting to re-sort its items?

  - by Drew Noakes

  Consider this code (type names genericised for the purposes of example): // Bound to ListBox.ItemsSource _items = new ObservableCollection<Item>(); // ...Items are added here ... // Specify custom IComparer for this collection view _itemsView = CollectionViewSource.GetDefaultView(_items) ((ListCollectionView)_itemsView).CustomSort = new ItemComparer(); When I set CustomSort, the collection is sorted as I expect. However I require the data to re-sort itself at runtime in response to the changing of the properties on Item. The Item class derives from INotifyPropertyChanged and I know that the property fires correctly as my data template updates the values on screen, only the sorting logic is not being called. I have also tried raising INotifyPropertyChanged.PropertyChanged passing an empty string, to see if a generic notification would cause the sorting to be initiated. No bananas. EDIT In response to Kent's suggestion I thought I'd point out that sorting the items using this has the same result, namely that the collection sorts once but does not re-sort as the data changes: _itemsView.SortDescriptions.Add( new SortDescription("PropertyName", ListSortDirection.Ascending));

• whats wrong with this regular expression c#?

  - by Greezer

  I runned into a problem with my regular expressions, I'm using regular expressions for obtaining data from the string below: "# DO NOT EDIT THIS MAIL BY HAND #\r\n\r\n[Feedback]:hallo\r\n\r\n# DO NOT EDIT THIS MAIL BY HAND #\r\n\r\n" So far is got it working with: String sFeedback = Regex.Match(Message, @"\[Feedback\]\:(?<string>.*?)\r\n\r\t\n# DO NOT EDIT THIS MAIL BY HAND #").Groups[1].Value; This works except if the header is changed, therefore I want the regex to read from [feedback]: to the end of the string.

• jQuery get Function Not Returning Data

  - by senfo

  I'm trying to use the jQuery get function to render the results of an HTML page in a div on my page. The result of the get function appears to be successful because the value of textStatus (in the following code block) is "success". The value of data, however, is always empty. $(document).ready(function() { $.get('http://www.google.com', function(data, textStatus){ $('#RSSContent').html(textStatus + ' ' + data); }); }); Any idea what I might be doing wrong? Note: The final code will query an RSS feed, which I plan on transforming and rendering as HTML in the RSSContent div. I simply used http://www.google.com for testing purposes.

• Handling duplicate nodes in XML

  - by JYelton

  Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)

• click-event doesn't fire if blur changes layout

  - by rag

  I have a form with blur-events bound to the required fields. Then there is a "Cancel" Button which simply calls an URL (button is an image with click-event). When leaving one of the required fields a warning is written to the page saying that field xy is required. - this causes a layout shift, meaning all the fields and the buttons are moved down a little bit because of the text inserted above. The tricky thing is this: when the focus is in an empty but required field and you click the cancel button, the required-warning is written to the screen but the click-event on the cancel button doesn't fire. I think this is due to the layout shift. The mouse cursor doesn't hover over the button anymore, because the button scrolled down. Has anyone a good idea how i could solve this?

• Wordpress Trackbacks Not Being Applied

  - by Dustin Digmann

  I am using Wordpress 2.9.1. I recently noticed the trackbacks are not being sent - internal or external. I see two issues I would like to solve. 1) My site has a default, global ping hub which it should notify. This value is not being set into the 'to_ping' value in the *_post table. 2) When I manually enter a trackback in the post, I notice the 'to_ping' value is properly set. It never sends the ping though. The 'pinged' value is always empty. With older versions of WP, this seemed to work automatically.

• Forcing WCF proxy to generate an alias prefix

  - by Sean Campbell

  To comply with a clients schema, I've been attempting to generate a WCF client proxy capable of serializing down to a structure with a root node that looks like the following: <quote:request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:quote="https://foo.com/services/schema/1.2/car_quote"> After some reading, I've had luck in updating the proxy to include the required 'quote' namespace through the use of XmlNameSpaceDeclarations and XmlSerializerNamespaces [System.SerializableAttribute()] [System.ComponentModel.DesignerCategoryAttribute("code")] public partial class request { [XmlNamespaceDeclarations()] public XmlSerializerNamespaces xmlsn { get { XmlSerializerNamespaces xsn = new XmlSerializerNamespaces(); xsn.Add("quote", "https://foo.com/services/schema/1.2/car_quote"); return xsn; } set { //Just provide an empty setter. } } ... which delivers: <request xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:quote="https://foo.com/services/schema/1.2/car_quote"> however I'm stumped as to how to generate the quote:request element. Environment: ASP.NET 3.5 Thanks

It works on firefox, but safari just shows an empty download window. IE also can't get the file. Below is the example link.

• Show them the default, and allow them to press escape or Ctrl-Z

  - by cf_PhillipSenn

  I have a table cell, and when the user clicks on it, I replace the contents of the table cell with an input tag with the current contents as the default. But I don't like it's behavior because there's a chance that the user can delete the contexts on the input simply by clicking on it a second time. $('.LastName').live('click', function() { var myText = $(this).text(); $(this).empty().append('<input name="LastName" id="LastName" value="' + myText + '" />'); document.myForm.LastName.focus(); }); Q: How do I give the user a default, plus allow them to press the escape key or Ctrl-Z while in the middle of an edit?

• ExpressionEngine 2 module "tag cannot be processed"

The module is installed and the backend is running fine.
