  • USING JSON SERIALIZATION FOR CODE BEHIND-JAVASCRIPT DATA COMMUNICATION

    Many of us went through a scenario like, can us pass a full of C# type/class to the javascript? Modify from there and again return back to C#? The difficulty is that JavaScript only knows string format comared to C# which has many data types. So how we can pass an entires class to JavaScript? Here we need to handle with JSON serialization techniques.

  • Going Beyond the Relational Model with Data

    SQL is a powerful tool for querying data, and for aggregating it. However, you can't easily use it to draw inferences, to make predictions, or to tease out subtle correlations. To provide ever more sophisticated inferences to businesses, the race is on to combine the power of the relational model with advanced statistical packages. Both IBM and PostGres are ready with solutions. And SQL Server? Hmm...

  • Is Juju deploy data accessible on the instances?

    - by ric_harvey
    When you launch an instance and explicitly name it using: juju deploy lamp website1 Is there a way on the newly created instance to get the data that tells the machine that its: called website1 or even better: a unit number such as website1/0, website1/1 etc etc The reason for doing this is that in my charm I wish to set the hostname to this value. I did wonder if it was set via ec2metadata but it doesn't seem to list this information.

  • sys.dm_os_performance_counters Data Pivoted

    - by NeilHambly
    At times I often want to know what is happening inside my SQL Servers, there are of course a multitude of ways I could "peek" into the activity that has been happening, Sometimes I just need to get a quick summary of those facts, maybe just to know if anything unusal has happened I'm not yet aware of, an easy way I can do that is to query the DMV sys.dm_os_performance_counters, As t here are tons of blog posts already out there on using the data from this DMV, I'm not going to focus...(read more)

  • Sorting data in the SSIS Pipeline (Video)

    In this post I want to show a couple of ways to order the data that comes into the pipeline. a number of people have asked me about this primarily because there are a number of ways to do it but also because some components in the pipeline take sorted inputs. One of the methods I show is visually easy to understand and the other is less visual but potentially more performant.

  • Is there a problem in having same product with different names in different pages?

    - by guisasso
    When ot comes to structured data, schema.org for products, Is there a problem in having the same product with 2 different names in 2 different pages for layout reasons? Example: Category page with many products. Objects appear in smaller divs that don't fit complete name vs product page totally dedicated to one product that fits all the information. Category Page: <span itemprop="name">Dell 30" Monitor</span> Product Page: <span itemprop="name">Dell UltraSharp 30" LCD Monitor</span> Thanks

  • Conditional Regular Expression testing of a CSV

    - by Alastair Pitts
    I am doing some client side validation in ASP.NET MVC and I found myself trying to do conditional validation on a set of items (ie, if the checkbox is checked then validate and visa versa). This was problematic, to say the least. To get around this, I figured that I could "cheat" by having a hidden element that would contain all of the information for each set, thus the idea of a CSV string containing this information. I already use a custom [HiddenRequired] attribute to validate if the hidden input contains a value, with success, but I thought as I will need to validate each piece of data in the csv, that a regular expression would solve this. My regular expression work is extremely weak and after a good 2 hours I've almost given up. This is an example of the csv string: true,3,24,over,0.5 to explain: true denotes if I should validate the rest. I need to conditionally switch in the regex using this 3 and 24 are integers and will only ever fall in the range 0-24. over is a string and will either be over or under 0.5 is a decimal value, of unknown precision. In the validation, all values should be present and at least of the correct type Is there someone who can either provide such a regex or at least provide some hints, i'm really stuck!

  • Asp.net MVC jQuery Ajax calls to JsonResult return no data

    - by Maslow
    I have this script loaded on a page: (function() { window.alert('bookmarklet started'); function AjaxSuccess(data, textStatus, xmlHttpRequest) { if (typeof (data) == 'undefined') { return alert('Data is undefined'); } alert('ajax success' + (data || ': no data')); } function AjaxError(xmlHttpRequest, textStatus, errorThrown) { alert('ajax failure:' + textStatus); } /*imaginarydevelopment.com/Sfc*/ var destination = { url: 'http://localhost:3041/Bookmarklet/SaveHtml', type: 'POST', success: AjaxSuccess, error: AjaxError, dataType: 'text',contentType: 'application/x-www-form-urlencoded' }; if (typeof (jQuery) == 'undefined') { return alert('jQuery not defined'); } if (typeof ($jq) == 'undefined') { if (typeof ($) != 'undefined') { $jq = $; } else { return alert('$jq->jquerify not defined'); } } if ($jq('body').length <= 0) { return alert('Could not query body length'); } if ($jq('head title:contains(BookmarkletTest)').length > 0) { alert('doing test'); destination.data = { data: 'BookmarkletTestAjax' }; $jq.ajax(destination); return; } })(); when it is run locally in VS2008's cassini the ajax success shows the returned string from Asp.net MVC, when it is run remotely the ajax success data is null. Here's the controller method that is firing both locally and when run remotely: [AcceptVerbs(HttpVerbs.Post | HttpVerbs.Get)] public string SaveHtml(string data) { var path = getPath(Server.MapPath); System.IO.File.WriteAllText(path,data); Console.WriteLine("SaveHtml called"); Debug.WriteLine("SaveHtml called"); //return Json(new { result = "SaveHtml Success" }); return "SaveHtml Success"; } Once i have it working I was going to remove the GET, but currently accessing the SaveHtml method directly from the webbrowser produces the expected results when testing. So there's something wrong in my javascript I believe, because when I step through there with chrome's developer tools, I see the data is null, and the xmlHttpRequest doesn't appear to have the expected result in it anywhere either. I'm loading jquery via http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js
