Code generation - An easy way

Recently I read about Text Template Transformation Toolkit (T4), I was really amazed by this because I thought only CodeDOM was the only way to generate code.

Text Template Transformation Toolkit (T4) is template based code generation engine which comes with Visual Studio 2008(It is not a framework feature).

This simple example shows how powerful it is -

if you have a string array and you want to generate a strongly typed enum from this.

XUL - Create cross platform application with ease

You want to create simple GUI cross platform application without knowing the high level programming languages like C++, Java, C#~(using mono)? XUL is that answer.

Yes it is possible using XUL, the prerequisites  for this is, knowledge of a declarative programming language(like HTML or XHTML, XAML etc...) and JavaScript.

XUL is basic building block of the Firefox UI and as we know Firefox works in Windows, Linux and MAC.

Actually XUL is a language which run on the XULRunner(Gecko) runtime from Mozilla.

If you really wants see how Firefox created this UI, go the FireFox installation folder. Normally it will be "C:\Program Files\Mozilla Firefox\". Under that installation root folder, find a folder named "chrome". Firefox has packaged the xul files in a zip format and they have renamed it as ".jar". So look for a file "browser.jar" and rename it to zip. Extract it and have a look at "content\browser\browser.xul". This file holds the UI definition for Firefox.

To learn more about XUL, refer these web sites

ASP.NET AJAX - Calling server side methods from client side

ASP.net AJAX has got nice bridging between your server side and client side technologies. Using the ASP.net AJAX you can easily call a method in a page. The restriction here is that, the methods your are trying to call should be static and public.

This feature(calling server side static method) is not enabled by default, so you have to manually enable this and it is very very simple; just set the "EnablePageMethods" property of the "ScriptManager" to true like this
