Visual Basic Report this article as Inappropriate to us !!!Login to Reply

I've been hearing a lot about the role of visual basic and Map Objects in the future of GIS. Does anyone use VB with GIS applications? Is it a good idea to learn VB to advance in the GIS world?

You may want to look at VB if you are going to use newer versions of Arc/Info, ArcView and especially MapObjects from ESRI, or MapX from MapInfo or even MapGuide from AutoDesk.

ESRI went from Avenue to VB as their embedded scripting with their jump to ArcView 4 and Arc/Info 8.

MapObjects and MapX are OCX's (controls) that can be embedded within a VB application.

VB will also give you a good foundation for programming any web application using ASP.

I was on a team of 3 programming a desktop demographics analysis system called MarketMath while at Compusearch (now part of MapInfo) using VB, ArcView, MapObjects and switched to MapX (when acquired by MapInfo).

In older days GIS applications used their own customization languages. But now Visual basic has emerged as a leading customization language in GIS apps. Whether it be Team GeoMedia of Intergraph, MapObjects or MapXtreme. It would be a good idea to invest time on learning Visual basic and OOP technology.

I would highly suggest learning VB if possible. In the ESRI case, all of the backend services to each product such as ArcIMS and ArcSDE provide API interfaces that can be easily called from VB.

In the interest of the general internet community, ActiveX Controls (OCX) as previously mention work great, but are generally not accepted by large coroporations due to security risks with web browsers and the concept of tricking uses to download "potentially damaging" as Micro$oft puts it, activeX controls.

ActiveX dlls on the other hand can be of mass benefit as they run server side on the web server and can automate many many virtualy any task given the will power to write it.
