Brian,
Thanks for the reply. I realised that the SDK was written for VC++ 2003. However there is usually no real reason for needing the latest compiler. I have no intention of spending the £500 or so upgrading from VC++6 when I have no other need for the upgrade!
Are you saying that MACH3 plugins cannot be compiled in VC6? or just that 2003 is the version you are using??
Thanks
Simon
