NET Internationalization with database resource provider and custom cultures

.NET Internationalization with database resource provider and custom cultures

Database storage is a popular option for Web-application resources, for a number of reasons. You can probably guess, at some point with a site that has thousands of pages and multiple-thousand resource entries, using assembly resources might not be ideal. It will add to run-time memory usage, not to mention the increased number of assemblies loaded into the application domain. Both of these results can have a negative impact on performance for extremely large sites, making the latency of a database call worthwhile. Database resources might also provide a more flexible and manageable environment for the localization process, for reducing duplicates, for intricate caching options, and for storing possibly larger blocks of content. Lastly, allocating resources to a database makes it possible to support more complicated hierarchies of translated content, where customers or departments might have customized versions of the text that is then also localized.

Small things about .NET

Sometimes I need to build string from strings array spparated by any simbol, so I found this sample:

string[] strArr = {"1","2","3"};
string output = "";

for(int i = 0; i < strArr.Leght;)
output += strArr[i] + ((strArr.Leght > ++i) ? "," : "");

Result: 1,2,3

Create site

Create site with Blogger as CMS and Picasa as Photoalbum

One day I decide to create my personal site: http://panshin.blogspot.com . I didn't want something difficult. I was need site with simple CMS manager and with photo album. Also I wanted to practice in using Mootools library with Google API. So I decide use Blogger as site holder and CMS manager, Google Pages as javascript and images holder and Picasa as album manager. A structure of the site you can see on following diagram.

I have google account. If you have google account you can use it for registration on blogger.com, pages.google.com and picasa.com. So in blogger I created blog per page on my site. A main page blog I used to entring point to my site. Also I customized XML template of the blog. I changed the layout of page according to my design, and deleted all old content of XML. In additional I added to header, links to javascript and CSS files.

So the base of my site was created.

I started javascript coding. The structure of content you can see on following diagram.

When user pressed on button in menu bar, I started loading content from blogger according to the button.

You can see the script that do it at: http://panshinspace.com/lib/blog.js

The following script is loading all post of blog in Json format.

var script = document.createElement('script');

var src = 'http://www.blogger.com/feeds/'+

this._blogId+

'/posts/default?alt=json-in-script&callback='+

this.options.objName+

'.onGetDataComplete';

if(this.options.orderBy)

src += '&orderby='+this.options.orderBy;

script.setAttribute('src', src);

script.setAttribute('id', 'blogJsonScript_' + this._blogId);

script.setAttribute('type', 'text/javascript');

document.documentElement.firstChild.appendChild(script);

After loading the script call to function that run by Json objects and fill content holder with content.

A script that loading albums from Picasa look different but concept is same: http://panshinspace.com/lib/album.js

Converter Ip->Number / Number->Ip

Convert IP Address to IP Number

Converter

Ip->Number / Number->Ip

Ip:

Calculate

Clear

Number:

Convert Ip to Ip Number

Ip = AAA.BBB.CCC.DDD
Number = 256^3 * AAA + 256^2 * BBB + 256^1 * CCC + 256^0 * DDD

Convert Ip Number to Ip

Ip -> AAA.BBB.CCC.DDD

Floor - returns the value of a number rounded DOWNWARDS to the nearest integer.

DDD = Number % 256
CCC = Floor(Number / 256) % 256
BBB = Floor(Number / 256^2) % 256
AAA = Floor(Number / 256^3) % 256

Delay Capture - When Map grabber the map in map display program (Firefox), to load new images take some time. So you must set the parameter according to speed image loading.
Number of X/Y Steps - How match steps to do.

- Output image settings:
Divide Image X/Y - By how match steps divide the output image. Some programs that using output maps on pocket PC, take a lot time to load big image.
Map Path - The output image folder.

- With GPS calibration - Enable GPS automatic GPS calibration of output map.

- Show/Hide points - show/hide the map settings and GPS calibration points.

Press the button Start.

Know Bugs:

found by me and another users.
- Memory out when grabbing more than 10X10 screens.

TODO:

what in next version.
- grab large size maps
- The GPSTuner have auto map loading feature. We can use maps with different resolution, and different level of information on map. That provide option in time of zoom out or zoom in, change maps automatically. So I want to add feature - grabbing maps with some levels of zoom.
