Web Services for the Enterprise using VB.NET
Price: US $995 /UK £695 +VAT | Duration: 2 days
Who Should Attend?


Experienced VB programmers with a good understanding of .NET concepts.

 
Pre-requisties
  • Basic awareness of .NET and VB.NET (preferably gained via our course 'Introducing VB.NET')
  • Understanding of Web concepts (eg HTTP and XML)
  • Familiarity with ADO and SQL
  • Experience with designing and building components (eg ActiveX DLLs)
Course Benefits

VB.NET represents a radical redesign of the hugely successful Visual Basic concept. Visual Basic has been rewritten from the ground up to take full advantage of the .NET platform, which will form the basis of Microsoft's product strategy for the foreseeable future. This is truly revolution, not evolution!

This course offers experienced VB users a three-day immersion in the product, which introduces the key concepts and answers the questions about the capabilities of the new platform, implications for existing applications, deployment, and many other issues.
You Will Learn How To:
  • Understand the purpose of ADO.NET
  • Learn the reasons for building and using Web Services
  • Explore the Web Service features provided by ASP.NET
  • Understand SOAP
  • Design and Build Secure, Scaleable Web Services
  • Create Web Service clients using VB.NET and VB6
  • Build advanced Web Services using .NET Remoting
  • Use Enterprise Services (MTS and COM+ features) with Web Services

Course Overview

After an overview of Web Services and SOAP, we build Web Services using .NET. Important concepts like security and deployment are examined. We build clients that can "consume" Web Services, including VB6. We also examine the .NET Remoting infrastructure and compare it to DCOM
Finally, we show how Web Services are used with existing MTS and COM+ technologies.
