Shamil, Sorry, you are an active list member of some renown and I just assumed that you needed no introduction. Just for everybody's edification, Shamil Salakhetdinov from St.Petersburg, Russia, my e-mail fellow (and long time friend) and an age-old AccessD member, helped me to get into the DEEP-Object Concept and to make the first trial port/test/POC of a small part of my framework to his Deep technology back in June '99, is the source of ALL of my knowledge re Withevents. That's no joke folks. Withevents is not easy to get information about. None of Access' help files do more than mention the keyword. Very few published books even mention it. I still call my classes dclsXXX in honor of his Deep technology moniker. I have come to the point where I understand Withevents well but I wouldn't have a clue had it not been for Shamil and his pioneering work in the subject, and his willingness to share his knowledge and ideas by publishing his findings on his web site (and work with me offline to bring me up to speed). I am dead serious when I say Withevents and classes has completely changed the way I program in Access, and I am equally serious when I say I owe it all to Shamil.

And it's natural that it needs some time to "have one's mind properly shifted/adapted" to it - then it starts looking easy but only for you and for some others, who have reached a certain level or understanding of how it works and how it can be naturally (and easily) applied for real-life tasks... > from this Russian Guy (Shamil) John, but why Shamil in round brackets? Why this Russian Guy? Why not "Shamil Salakhetdinov from St.Petersburg, Russia, my e-mail fellow and an age-old AccessD member, who helped me to get into DEEP-Object Concept and to make the first trial port/test/POC of small part of my ADFramework back in June '99"? Just wondering what brackets around my first name mean, Shamil :) P.S. BTW, just out of curiosity - have a look at VB.NET(C#) code for WinForms and then compare it with some code samples from this article: http://smsconsulting.spb.ru/shamil_s/articles/deep4sa.htm written in autumn 1998... ----- Original Message ----- From: "John W.
