Thanks for your reply Scott ! Looks like I'll have to bite the bullet and order ! It's not the money that bothers me, just the hassal factor and the time it takes ! Rgds, Steve

This article sparked some interest for me, so I thought I'd learn some more about this area : http://www.codeproject.com/useritems/DrvFltIp.asp I'm attempting to write some TDI Driver Interface code, and need the Win2k DDK libraries. I have VC++ .NET Pro and these DDK libraries aren't available within the Visual Studio by default. After visiting the MSDN site : "We will not be offering this DDK as a download on this Web site. However, it is part of the standard MSDN® subscription download and ships with the February 2003 edition." I was curious as to whether anybody knew of an alternative download site, so as to provide immediate access to these ? Many thanks :wtf:, Steve ps : Apologies if this is the wrong forum, I'm assuming that the majority of drivers are written in VC++, so this msg may attract more people "in the know" :-D
