Developed User Interfaces (UI) and SQL back end using VB-generated objects (desktop)
HTML and XML generated using ASP (Internet). Parsing for XML xpath
Most often used for server-sided ASP (Active Server Page) and ASP.Net
Recent Web application development using VB.Net with ASP.Net version 2.0 framework,
ADO.Net, BL business layer, Visual Studio 2003 & 2005 with VSS (Visual Source Safe)
Layers of Master pages, ASPX pages, ASPX.vb, business layers, and the .Net data objects of
ADO.Net and stored procedures for parameterized SQL server
Ajax and javaScript for UI development. Crystal Reports.
Convenient security and server-sided controls simplify web application development.
HarborObjects
Now Optimizations of VB.Net environment for UI. Legacy migrations.
Continue to support traditional server-sided Basic ASP and develop with javaScript for UI.
Original Basic language, including file I/O, is still supported in .Net through the System libraries.

C:>run
  • The Basic language was traditionally interpreted
    • Rapid Development (RAD)
    • Convenient debugging
    • Ease of iteration to perfection
    • Variables were available in break mode
    • Compilers were available for production
    • Laboratory usage was migrated from Fortran

  • Use of VB DLLs by Microsoft in Win 3.x, 95, 98 and office applications created problems
    • Security issues related to sharing of DLLs
    • Ease of modification related to ASCII within EXEs
    • Use of registry rather than ini files obscured DLL reliability
  • Evolution to Managed Code
    • Huge memory model and freedom from the Intel segmented model decreased attention to garbage collection
    • Protected memory reduced access to OS facilities
    • Unlike C/C++, VB environments never interfaced well with Win16/32 APIs
    • Visual environment encouraged module incorporation and run-time controls
  • .Net Implementation of VB.Net
    • No advantage over C# for RAD
    • Interpreted nature reduced to JIT line-compilations
    • Only syntactic differences differentiate VB.Net from C#.Net
