with bing! site search plug-in which will be released on open source section next week!

It’s easily integrate but sometime you might need more convenience when integrate it to your website. Of course using XML or JSON which is the basic data structure is not that difficult, but I think most of time, for the integration itself, the most easiest and convenient is managing HTML. On the view if you are rendering the content partially, later you can use AJAX to replace the partial HTML content dynamically other than managing JSON on client side: we need rich client application, but if it lose weight a little bit, why don’t we make it lighter?

So, let us apply the MOD to it. It’s MIT license, so, no harm to mod it. Just pay a little attention to it’s license file: Gallery CMS comes with 2 licenses, one license is MIT license which represent itself, and the other license is derived from CodeIgniter which the basic framework.

1.\application\controllers\view.php //Add the following codes to it:

function html() {
$data['row'] = $this->gallery_xml->viewXML();
$this->load->model(’settings_tbl’);
$data['settings'] = $this->settings_tbl->viewSettings();
$this->load->view(‘view_html’, $data);
}

2. On\application\views\ folder, create a file view_html.php

Please note that, you can make the view html a full html or you can partially render it like this:

<?php if(isset($row)) {?>
<div>
<?php foreach($row as $r){?>
<?php if(isset($r->images)) {
foreach($r->images as $img) { ?>
<div>
<div><a href=”<?php echo base_url();?>uploads/<?php echo $img->filename;?>” target=”_blank” title=”<?php echo $img->caption;?>”><img src=”<?php echo base_url();?>uploads/<?php echo $img->thumbnail;?>” border=”0″ align=”absmiddle” width=”<?php echo $settings[0]->thumb_width; ?>” height=”<?php echo $settings[0]->thumb_height; ?>”/></a></div>
<div><?php echo $r->title;?></div>
<div><?php echo $r->description;?></div>
</div>
<?php } ?>
<?php } //if  ?>
<?php } ?>
<div style=”clear:both”></div>
</div>
<?php }?>

After that, you can use: http://<GALLERY_CMS_WEBSITE>/index.php/html  to retrieve the HTML content. In our mod above, it is just partial HTML, so you can jQuery it:

$.get(‘http://<GALLERY_CMS_WEBSITE>/index.php/html ‘, null, new function(resp){$(‘#html-container’).html(resp);});

Nice and easy.

Sure you can. With MVC routing facilities, you can define your customized redirect logic: CREATE AN EMPTY MVC PROJECT, MODIFY GLOBAL.ASPX.CS FILE ONLY ON THIS EXAMPLE:

First of all, define two objects which implemented IRouteHandler and IHttpHandler, you can feel free to define those two objects on Global.aspx.cs file:

//@Implements IRouteHandler
class RedirectRouteHandler : IRouteHandler
{
private string newUrl;
public RedirectRouteHandler(string newUrl) { this.newUrl = newUrl; }
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
return new RedirectHandler(newUrl);
}
}

//@object implements IHttpHandler
class RedirectHandler : IHttpHandler
{
private string newUrl;

public void ProcessRequest(HttpContext httpContext)
{
httpContext.Response.Status = “301 Moved Permanently”;
httpContext.Response.StatusCode = 301;
httpContext.Response.AppendHeader(“Location”, newUrl);
return;
}
}

Then add one line on RegisterRoutes(RouteCollection routes) method (in Global.aspx.cs):

routes.Add(new Route(“{*pathInfo}”, new RedirectRouteHandler(@”http://koumei.net”));

Now all request to the website will redirect to “koumei.net” permanently.

I got 2 souvenirs, such as t-shirt, caps, but all are related to Microsoft stuff. You want to get the t-shirt? well, need to make some efforts. Everyone who attends the meeting will get a magic cube from the host, and need to fix the cube to a designated image. After all, once cubes are fixed, the host sorts them out and put them in a frame, to shape a IE icon:

The Frame of Magic cubes,Everyone is involved

I think the most useful sessions are about how jQuery works peacefully with ASP.NET and VS.NET 2010 new features, and one interesting session talking about the future data representation, and introduce Pivot. Microsoft considers the cooperation with jQuery is a giant step forward, and shows its ambitions to open source community. Microsoft starts to contribute to open source community and make a lot of effort towards it, look forward to seeing its powerful tool released in months to come.

Frankly Speaking - Talk Show in REMIX10

One thing somehow a little bit disappointed me is on this event, Microsoft doesn’t show any thing about HTML5 and CSS3, I think because Microsoft more focuses on sliverlight technology?

As the name implies, the great convenience comes great complication inside. Lambda expression is too important to understand, it is useful and I think it is good to know how it works. Well, it’s not as complicated as we think, just a little bit confusing when using it.

First of all, Lambda is used for 2 purposes. 1 is to simplify delegation, 2 is to create expression tree. In my case, I need to create lambda expression to create dynamic query.

Imagine the following usecase:

In your product table, there is a field called “Tags” and it’s used for storing the CSV (comma separated value) like “car, mazda, suv, luxury”, you have many records:

Product Table: (Table name: ProductTable)

ID    ProductName    Tags
1    Tow bar        car,mazda,suv,luxury
2    Cup holder    car,luxury
3    Phone holder    car,mazda
4    FM Transmitter    car,suv
5    Queens bed    luxury
6    DVD Burner    car,BMW,x5,luxury

When your searching criteria is
“mazda” and “luxury”, the following records would be selected out:

ID    ProductName    Tags
1    Tow bar        car,mazda,suv,luxury
2    Cup holder    car,luxury
3    Phone holder    car,mazda
5    Queens bed    luxury
6    DVD Burner    car,BMW,x5,luxury

In ancient SQL age, you would probably write a SQL like this:

It is IMpossible to create SQL like above except the project scope tells you the fixed keywords that would be used, the keywords should flexible. Then the code would be as much as:

You must be very exciting that your code supports as many keywrods as it can. (I did before, I mean I would be very exciting when the code filled with logical stuff, LOL, of course, not now, that’s what geek did before~ )

Back to the reality, to the modern age, with the lambda expression, what you need to do is:

(pre-condition: you have created corresponding domain model which mapped to the database.)
The domain object or entity would look like:

to fullfill the same kind of logic as the stone-aged people do, you just need to

Since so far, you still feel comfortable with this, but after minute, you would probably wanna go back stone age, how do we dynamically create the query in this case? Unfortunately, there is no short-cut for this, but many people provide lots of solutions on the Internet. We can either download some source codes about dynamically query on Internet or just grab the codes from the blogger’s website.( Most of time, you can’t use all of their codes posted on the blog, the codes are broken and bad structure, remember what Koumei always suggests, absorb the mind from the other coders, do not copy the code they provided. )

But in here, I would rather to use Expression Tree to implement the dynamic query.

First of all, we need to create an expression, because it would be applied to IQueryable.Where(Expression<Func<ProductTable, bool>> expression), so the expression should be defined as:

Again, you can’t copy the code, since you would NOT have the same object like ProductTable and the same “Tags” property as I do. Luckily, you still can copy the code that I provide later, which is using the magic of template or generic programming. Before that, let us see how to use it:

Since so far, I am 100% sure you can do it like refactoring, re-structuring to optimize your code. However, I would like to provide the code which can be general used:

The usage is similiar:

Not that hard, right?

Enjoy the powerful weapon, but don’t hurt yourself, bacause the deadline is ahead!

The improvement includes:

• Uses template engine to show widget. No more embedded HTML.
• Moves all functions to a util class
• Supports up to 5 RSS
• Still reads RSS feed dynamically on client-side

The feature version will be released next day or two, will enhance javascript flexibility. E.g., not compulsorily needs jQuery framework.

You can download the widget on http://www.koumei.net/download/wp-webKlip.zip

Wordpress Widget: Client-side RSS util, The Web Klip Released!

The following files should be updated (if you want to satisfy IE 8 users):

• \components\com_virtuemart\js\mootools\mootools-release-1.11.js  (update to 1.21)
• \components\com_virtuemart\js\mootools\mooPrompt.js (you have to revise it manually. Should change a lot of JS class definitions in accordance with mootools 1.21 syntax)
• \components\com_virtuemart\js\slimbox (update to slimbox for mootools 1.21)
• \components\com_virtuemart\themes\default\theme.js (you have to revise it manually. Should fix a bug on line 59, change to var timeoutID = setTimeout( ‘document.boxB.close()’, 3000 );)

Besides updating corresponding files, you can also disable Ajax function on the administration page. Or.. Wait until next stable release of VM). If you need the files above, just leave me a message, and I will pack them up for you.

Download: http://www.koumei.net/download/wp-webKlip.zip

Not too much special effects. In order to make the contents which read from the underneath javascript show themselves up naturally. Not in a harsh.

If you want to try, just download the widget on http://www.koumei.net/download/wp-webKlip.zip , then unzip to wp-content/plug-ins/ folder, and activate the plugin and add widget to you wordpress blog.

Before using this widget, there are some notes you should know:

1. Defects:
   Currently only support ONE RSS excerpt.
   Only shows the first RSS item.
   jQuery should be included on your blog.
2. Usability:
   Site that provide at least 1 item RSS feed could be refered by this widget.
3. Extension:
   Multiple-RSS and rollover will be available  on next release.

The Demo:

Picture 1. The plugin will be shown after you copy the unzipped file to your plugin folder

Picture 2. Add the widget to the “Widgets” menu on your administration panel. You can add a RSS feed to this widget

You can  find the demo on the right side of my blog.

The definition of my interface is:

Name: Rss2JSon
Interface: http://www.koumei.net/rss2json/
Method: GET
Parameter 1:  rss  – The URL of the rss content
Parameter 2: cb — The javascript callback function
Return: application/x-javascript
Example: http://www.koumei.net/rss2json/?rss=http://www.blogjava.net/max/rss&cb=<callback>  (A blog of my friend)

The callback function is very significant. Don’t forget to define a callback JS function on your script. The definition of the callback function should be similar as below ( parameter rss is an object, containing “title”, “link” and “description” and so forth<please go through RSS schema on item tag>.)

<script type=”text/javascript”> 

function myCallback(rss){
    var title = rss["title"];   // or rss.title
    var link = rss["link"];  // or rss.link
    var desc = rss["description"];  // or rss.description.
}

</script>

Now, you can embed the script to wherever you need.
<script type=”text/javascript” src=”http://www.koumei.net/rss2json/?rss=http://www.blogjava.net/max/rss&cb=myCallback”></script> 

Enjoy scripting.
