tHIS will not help, as i was waiting for this hell to arrive. But maybe father autocad can answer it, from the past, in principle.
Don't worry, i'll be going through it soon, and I've waited for others to go through hell in vbnet, so i can just bypass it to paradise above from their trek, fifty versions, fifty operating systems, 10,000,000,000 bugs, etc.
I too am awaiting the answer, but it will come, and yes, you will be re-writing, re-writing, rewiring, feeding those of us whose world we keep frozen in the xanadu of autocad 2000. (you will also be sustaining the cadaver of vb6, for wackward compatibilty for your users, uhhh, yourself, forever and ever, then onward into the ghastly gates/walker inspired future of computing! mind sucking blackholes of enjoyability, obsession and just plain fun! (seriously))
Good luck, but the true troopers will solve it, hence not a "project" anymore, it's a "solution" now!
And John Walker warned us... He is... well autodesk is now... sons of Bill Gates
if we couldn't laugh, we would all go insane... but this aint funny
