Creating cai on vb

If you are refering to a WBT/CBT learning course that will run on a LMS, then Visual Basic is not the best tool for the job. I've developed countless online learning courses, and you will need to use something lighter and more portable.

If you need to create training that will distributed on CD-ROM, you might get by with VB, but it's limited on what you can do in terms of simulation, user interactions, animation, audio and video playback. And it will not work on some platforms. Besides, you will need to also distribute an installation package.

During development, WBT/CBT programs have a high amount of edits/modifications during the development stage that VB will probably hold you back. A java application would be a better choice if you insist on going by way of an "Application".

Ideally, your approach should be as though you are creating an extremely interactive website. Tools like Dreamweaver, Flash, and Fireworks would be all you need. And your code can be written in VBscript or Javascript.

If you needed to hammer out something really quick, then tools like Lectora, Articulate Presentor, and Robo Presentor are among the "Rapid Development Tools" and are widely used. But they are limited.

Visual Basic, in itself is a challenge to learn if you don't already know how. If you do know how to use it (at an expert level) then you should already know how to create a CAI, as you call it. It would be impossible to demonstrate how in this forum.

If you have more questions about eLearning tools, I can help. But seriously, consider changing your approach.
