As I said in the comments - it's basically the example application from Chapter 2 of a "Learning to program" text book - I suspected as much as soon as I saw it - only lacked the proof to show where it was "lifted from". I don't have VB6 installed on my laptop - so if anyone wants to quickly compile it and take a bunch of screenshots - might be interesting. Personally I think Doylesoft is really taking advantage of people who don't know any better, anyone who was tricked into paying $79 for this deserves a full refund and an apology.
When put alongside Remlapsoftware KnowledgeBase http://www.remlapsoftware.com/ (which is completely free) it demonstrates only too well how far Doylesofts' attempt as a software Knowledgebase has to improve before it can seriously claim to be a competitor. Currently it is The world's ONLY "almost functioning" overpriced Knowledge Base.
The programmer really has an inflated view of "his" company and software.
DoyleSoft built the first knowledge management system designed exclusively for ease of use and open database design. This deep, rich experience with the Windows operating system has helped us in our efforts to make sure our software is the most compatible in the industry.
The company has made substantial investments in establishing the finest technical services in the industry, which enables DoyleSoft to develop the highest quality products possible.
Total and absolute garbage.
