• Wrapping Multiple Elements (jQuery)

  - by Nimbuz

  I've this piece of HTML: div.content div.one content div.two content div.three content I want to add two divs on top and bottom and wrap one div around it so it becomes: div.top div.wrapper div.content div.one content div.two content div.three content div.bottom I'm aware of the several wrap selectors (innerWrap, wrapAll etc..) but I'm not sure how to wrap 2 divs. The following jQuery might work, but is there a better way to write it? $('content').wrap('<div class="wrapper"></div'); $('.wrapper').before('<div class="top"></div>'); $('.wrapper').after('<div class="bottom"></div>');

• Ideas for loading initial data in an iPhone application?

  - by Derek Clarkson

  Hi all, In my app I want to load some initial data to show the user how it works. The app uses a CoreData managed sqllite db. SO far I've thought of 3 options: Write code into a class to programmatically create the data. Create a xml file in the apps resources and load through a NSXmlParser whose delegate creates the entries in the sqllite db. Same as option #2, but use a json file and bring in a 3rd party lib to read it. Are there other options I have not found yet? and given that I'm talking about perhaps 6 records per table when there are 3 tables, which would you choose?

• when text changed inputbox automatically updates next text boxes?

  - by James123

  Extension to my previous question http://bit.ly/c5yiVM I have 7 textboxes. If Top 1 textbox(Volume All Years) text changed, text need to be updated in next 6 inputboxes(Latest 2009 Volume to Latest 2014 Volume). I need javascript or Jquery for this. I will write Js textchanged() or focuschange() for top 1 textbox. So what should I write in focuschage() or textchanged methods(). I changed little bit in code. Now Html will like below. These textboxes have common CssClass. volumetextbox. Can we use this class and change text in all textboxes those have same CssClass. <tr id="row12_136" class="RegText"> <td style="width:420px;Padding-right:20px;">Volume All Years</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_136" tabindex="61" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_60" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2009 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_60" tabindex="56" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_61" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2010 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_61" tabindex="57" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_62" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2011 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_62" tabindex="58" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_63" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2012 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_63" tabindex="59" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_64" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2013 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_64" tabindex="60" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_65" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2014 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_65" tabindex="61" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td>

• Problem processing large data using Applet-Servlet communication

  - by Marquinio

  Hi everyone. I have an Applet that makes a request to a Servlet. On the servlet it's using the PrintWriter to write the response back to Applet: out.println("Field1|Field2|Field3|Field4|Field5......|Field10"); There are about 15000 records, so the out.println() gets executed about 15000 times. Problem is that when the Applet gets the response from Servlet it takes about 15 minutes to process the records. I placed System.out.println's and processing is paused at around 5000, then after 15 minutes it continues processing and then its done. Has anyone faced a similar problem? The servlet takes about 2 seconds to execute. So seems that the browser/Applet is too slow to process the records. Any ideas appreciated. Thanks.

• FlexBuilder 3 Linked folders not picking up as files.

  - by Jafin

  I am using Flex Builder 3 to write a flex component. I have created a real folder path \common. Under common I create a Linked Folder to Session. Session points to a shared source folder with a item with a namespace of common\Session\ClassName. When I go to compile the project FlexBuilder warns that it was unable to find the type. if I stop using Linked folders and create a physical \common\Session\ in my project and place SessionInfo.as in the folder then it works. just in case my textual explanation is a bit obscure here is the layout. \src\common\Session\SessionInfo.as namespace of SessionInfo is common.Session. If you need any further info just let me know.

• change/part doesn't work as expected with parse

  - by Rebol Tutorial

  According to http://www.rebol.com/docs/core23/rebolcore-15.html You can use change/part to parse and replace but that doesn't work well with this where I just try to replace the block <mytag > ... </mytag> by "MyString" content: {<mytag id="a" 111111111111111> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="b" 22222222222222222> </mytag> <mytag id="c" 3333333333333> </mytag> aaaaaaaaaaaaaaa aaaaaaaaaaaaaaa <mytag id="d" 444444444444444> </mytag> } mytag: [ to {<mytag} start: ( ) thru {<mytag} to {id="} thru {id="} copy ID to {"} thru {"} to {</mytag>} thru {</mytag>} ending: (change/part start "mystring" ending) mark: ( write clipboard:// mark input) ] rule: [any mytag to end] parse content rule

• Simulating brush strokes for painting application

  - by DrRobot

  I'm trying to write an application that can be used to create pictures that look like paintings using simulated brush strokes. Are there any good sources for simple ways of simulating brush strokes? For example, given a list of mouse positions that the user has dragged the mouse through, a brush width and a brush texture, how do I determine what to draw to the canvas? I've tried angling the brush texture in the direction of the mouse movement and dabbing several brush texture images along the path, but it doesn't look great. I think I'm missing something where the brush texture should shrink and grow on corners. Any simple to follow links would be appreciated. I've found complex academic papers on simulating e.g. oil paints but I just want a basic algorithm to use that produces OK results if possible.

• ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

  - by Phil Bennett

  My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

• How to correctly do SQL UPDATE with weighted subselect?

  - by luminarious

  I am probably trying to accomplish too much in a single query, but have I an sqlite database with badly formatted recipes. This returns a sorted list of recipes with relevance added: SELECT *, sum(relevance) FROM ( SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%milk%' UNION ALL SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%flour%' UNION ALL SELECT *,1 AS relevance FROM recipes WHERE ingredients LIKE '%sugar%' ) results GROUP BY recipeID ORDER BY sum(relevance) DESC; But I'm now stuck with a special case where I need to write the relevance value to a field on the same row as the recipe. I figured something along these lines: UPDATE recipes SET relevance=(SELECT sum(relevance) ...) But I have not been able to get this working yet. I will keep trying, but meanwhile please let me know how you would approach this?

• I get "stack level too deep" error when using a named scope

  - by Brian Roisentul

  I'm using ruby on rails 2.3.8 and when I write the syntax shown below I get the "stack level too deep" error message. The model is called Announcement and the line of the error looks like this: Tag.find(category_id).announcements.published Where published is named_scope :published, :conditions => "announcements.state = 'published'" I use this named scope in many other places and it works fine. What am I doing wrong? (the relationship between Tag and Announcement model is ok because if I remove the ".published" method from that line it works just fine).

  - by Ajay Pandey

  i have a UITextView object which i have created in interface builder with it's hidden property unmarked.Now i want this textView to be invisible when my application launches and first view appears.Further i want it to be displayed when a particular method is called.Now this is what i have written in view did load [mTextView setHidden:YES]; self.mTextView=[[UITextView alloc] init]; it hides the textView ats the first view appears but when my desired method is called and i write [mTextView setHidden:NO]; it does not show it again..

• build a chrome extension in order to upload images (from clipboard)

  - by dayscott

  I wanted to write a simple chrome extension in order to substitute the following sequence of steps which i have to do very often for university: make screenshot of something edit screenshot in Paint save unnamend.png to harddrive upload unnamed.png to imageshack.us/pic-upload.de or any other website share link of image with others. I don't care which image upload service to use, i just want automize this use-case in order to save time (I already red and did a getting-started chrome extension and checked out their API, but that's it, this page: http://farter.users.sourceforge.net/blog/2010/11/20/accessing-operating-system-clipboard-in-chromium-chrome-extensions/ seemed useful, but i couldn't make it overwrite my systems clipboard - moreover i can't find a tutorial which helps me further).

• Why wouldn't I be able to establish a trust relationship for a SSL/TLS channel?

  - by Abe Miessler

  I have a piece of .NET code that is erroring out when it makes a call to HTTPWebRequest.GetRequestStream. Here is the error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. I've read a few things that suggest that I might need a certificate on the machine running the code, but i'm not sure if that's true or how to do it. If I need to get a certificate, how do I do it? Code: var request = (HttpWebRequest)HttpWebRequest.Create(requestUrl); //my url request.Method = StringUtilities.ConvertToString(httpMethod); // Set the http method GET, POST, etc. if (postData != null) { request.ContentLength = postData.Length; request.ContentType = contentType; using (var dataStream = request.GetRequestStream()) { dataStream.Write(postData, 0, postData.Length); } }

• Searching for empty methods

  - by Brian McCord

  I am currently working on a security audit/code review of our system. This requires me to check all pages in the system and make sure that the code behind contains two methods that are used to check security. Sometimes the code in these methods get commented out to make testing easier. So, my question is does anyone know an easy way to search code, make sure the methods are present, and to determine which ones have no code or have all the code commented out. It would make my job much easier if I can get a list instead of having to look at every file... I'm sure I could write this myself, but I thought someone may know of something that already exists. Thanks!

• Rails application and multilingual content, Model dilemma

  - by dakull

  I'm writing in Rails a website that will be multilingual, for the application translation part i will use the simple I18n gem, for messages and everything related. Yet, all the content must be translated, and we're talking about lots of pages, that will be stored into the database ( like articles, news, etc. ) For now, I'm thinking of two approaches: Lets say i have a Pages table, the content in diff. languages, i will be storing it in a different table called PagesContent that will belong_to Pages and also to a Languages table. The problem here, is that I'll essentially duplicate the no. of tables needed. Pros: flexibility, in the box validation To skip that duplication i can serialize a hash into the content column of Pages, containing the translation. The problem here, is validation, arguably more code to write, and less flexibility when adding a new language. Pros: Less tables. Any other idea ?

• Converting delimited string to multiple values in mysql

  - by epo

  I have a mysql legacy table which contains an client identifier and a list of items, the latter as a comma-delimited string. E.g. "xyz001", "foo,bar,baz". This is legacy stuff and the user insists on being able to edit a comma delimited string. They now have a requirement for a report table with the above broken into separate rows, e.g. "xyz001", "foo" "xyz001", "bar" "xyz001", "baz" Breaking the string into substrings is easily doable and I have written a procedure to do this by creating a separate table, but that requires triggers to deal with deletes, updates and inserts. This query is required rarely (say once a month) but has to be absolutely up to date when it is run, so e.g. the overhead of triggers is not warranted and scheduled tasks to create the table might not be timely enough. Is there any way to write a function to return a table or a set so that I can join the identifier with the individual items on demand?

• Access to a single pixel in C#

  - by Malki

  Hello, I'm working on a school project right now. It's meant to be a 3D editing software, (like a very minimized version of Maya). I have to write it in C#, using the 'Windows Application Project'. I intend to implement all the 3D stuff myself, from projections to shading. My question is, how can I get direct access to a single pixel in the C# windows application? I know I'm going to have a main view port in the window. But I haven't decided yet how it will be made. Is there a built in object that I can use, that will let me define the boundaries of the view port, and then paint each pixel individually? (I'm just shooting in the dark here, I don't know much about C#. I mostly program in C) Thanks, Malki.
