What is Active Template Library (ATL)?

Active Template Library (ATL) is a set of library files that are used for creating various components in Microsoft ASP.NET (Active Server Pages). The entire library of ATL is designed in such as way it focuses on easing the process of creating control components in ASP. Also, the controls created using ATL are known for its efficiency, flexibility, and lightweight.

ATL and ASP

The website developer can utilize Active Template Library to create code for common gateway interface application or script in the HTML of the web page. This page is called as ASP (Active Server Page) and it is accompanied with (.asp) extension. Typically every code using ATL is written using a sophisticated object-oriented language called C++. The reasons for using this object-oriented language is that it facilitates the creation of compiled code which can run faster than the scripts and the code could be closely interfaced with the operating system. The only con about using C++ is its time consumption and difficult coding than the scripting language.

Object Wizard

It is very easy to set up primary structure of objects in ASP with the help of an object wizard available in ATL. This wizard also helps the developer to minimize the hand coding and speed up the creation of primary object structures.
