| The Demise of Visual Basic
Perhaps you use or are considering one of several LOS’s that are written in Microsoft’s Visual Basic (“VB” or “VB6”) programming language. If so, there is some very important information you need to know. First, you need to know that Microsoft has discontinued VB and is replacing it with another newer and very different language, called C#. C# is now Microsoft's language of choice for new applications that are to run on Microsoft’s .NET (“dot net”) web services platform. The reason that VB is being phased out is because supporting VB on .NET involved many technical compromises, so Microsoft simply chose not to support VB on .NET. .NET is Microsoft’s new web services specification, just like the Java Platform, Enterprise Edition (Java EE) is Sun Microsystems’ web services specification. There are two major differences between .NET and Java EE. First, Java EE has been around a lot longer and is much more widely adopted. With the sole exception of Microsoft, every major software company (IBM, Oracle, Novell, HP, SAP, BEA, etc.) participates in the open Java EE specification process and develops Java applications. Second, Java EE applications run on a wide variety of operating systems including Windows, Linux, Mac OS X, and many others. .NET only runs on Windows, locking you into Microsoft dependence and forcing you to accept their upgrades, ongoing license fees, costly support agreements, end-of-life plans, etc. When you choose Java applications, you are better served by the competitive marketplace. It is very important to note that Microsoft has already terminated “mainstream” support for VB! Critical VB updates are no longer available for free. Free telephone and online incident support is no longer available. And Microsoft support for VB will no longer be available in any way, shape or form after March 2008. For more information straight from Microsoft see: http://support.microsoft.com/lifecycle/?LN=en-us&x=14&y=10&p1=2971 What if your LOS vendor does not rewrite their system? VB applications do continue to run on Windows XP, and Microsoft promises the VB6 run-time components will be included in Windows Vista (fka Longhorn), the next major Windows version. But there are major unanswered questions regarding the compatibility of existing VB applications with Windows Vista, and about their performance. Ultimately your LOS vendor cannot just ignore the migration mandate. VB applications must be migrated or they will eventually die, and maybe sooner than you want. See http://msmvps.com/bill/archive/2005/03/13/38319.aspx for a brief discussion of this issue. So presuming that your LOS vendor does choose to rewrite its LOS, what hurdles do you and the vendor face? To simplify VB migration, Microsoft does offer a stopgap language called VB.NET. But in practice, the conversion from VB to VB.NET is quite difficult, as VB.NET is object-oriented and VB is not. Plus, VB.NET is hampered by the need to be somewhat backward compatible with classic VB. In fact, most experts agree that VB.NET applications will still have to be completely rewritten. Most VB developers agree that, with everything else equal, applications should be migrated to a language like C# or Java, not VB.NET. Unfortunately for these LOS vendors, rewriting their systems in these languages is a task that is disruptive and very costly, and will force the vendor to suspend its enhancement process, perhaps for years. And LOS’s that involve custom programming (VB or VB Script) will be doubly hard to rewrite. The fact is, the risks of rewriting a complex application like an LOS are enormous and probably not acceptable to most financial institutions. There are numerous articles that describe the dilemma faced by VB developers: Study: Developer Use of Visual Basic
Plummets (2006-11-29 eWeek) http://www.eweek.com/article2/0,1895,2065392,00.asp "Moreover, Evans said, "As expected, developers are finally leaving VB6 and earlier versions; they're also leaving VB.NET; which is down by 26 percent. This means Java now holds the market penetration lead at 45 percent, followed by C/C++ at 40 percent, and C# at 32 percent." "Visual Basic.not" (Karl E. Peterson) http://vb.mvps.org/vfred/Trust.asp "Support Classic VB..." http://classicvb.org/ “Should Microsoft be sued for dropping

ASC understands how daunting it is to rewrite an existing LOS. Our award-winning UNI-FORM Loan Processing System faced a similar dilemma some years ago. The language in which UNI-FORM was written was rapidly losing popularity and support. ASC undertook the difficult task of rewriting UNI-FORM completely from scratch, in Java. The project took three years, during which ASC was unable to market an LOS. Thankfully our PowerSeller Secondary Marketing and Risk Management System was enjoying tremendous market acceptance. Many other LOS vendors don’t have another revenue stream to fall back on. We’re glad to say we are now back in the LOS business and stronger than ever. You can be assured that PowerLender's Java platform will survive the caprices of any single language vendor long into the future. But the pain and anguish we endured during the conversion? We don’t wish that even on our competitors in the LOS world. Thank you for taking the time to understand the situation faced by
companies offering LOS’s written in Visual Basic. We hope the
information presented above helps you make an appropriate LOS selection
decision. |
