ok folks...i am writing a program that implements the alpha transparency feature of Windows 2000 using the new API declarations. anyway, i am assuming that MANY of my users will be running on Win9x machines. but i don't want to leave the 2000 users without this really cool feature. so, what i want to do is write a code that will check to see if the Windows 2000 operating system is running, and if not it will disable, say for now, a command button. any thoughts or suggestions? this is quite urgent since microsoft hasn't had time to fully document this yet...at least not that i've found. thanks.
