 ASP.Net Programming Using Visual Basic

  Course Code - GN-154   Duration - 3 Days

Microsoft’s original implementation of ASP was powerful and popular, but had a number of major limitations particularly in respect to the separation of page design and programming.

ASP.Net 1 initiated a new model which provided ‘code- behind’ to separate the coding and design, and allowed web pages to be designed in much the same way as desktop forms. ASP.Net 2 improved on this in a number of areas, particularly flexibility and simplicity.

 

 Prerequisites

 
 

This course covers ASP.Net 2, or 1.1 on request, and can also provide a full coverage of the VB.Net language. The course length can vary from 2 to 5 days depending on prior experience of the .Net languages or their predecessors, but the overview given below assumes prior experience in Visual Basic 6 or similar.
