Hi,

I wrote in a while back about writing to the 9th meg a PV100 framegrabber.
Since then, all went smoothly (thanks to suggestions) and I finished the 
routines I wanted. Some of them is assembly, but most is Pascal (for windows).
The routines work fine on their own, but as soon as I put them into a DLL for
another programmer doing the front-end in Visual Basic, they don't work at all,
in fact they don't work even if I call them from Pascal. 

I have checked my code many times, and it conforms to the help files 
description. Ok, I thought that maybe something wasn't right in my own routine
so I commented the whole thing out, just leaving the declaration 'procedure
... begin end;' and it still gave general protection faults etc.

I have spoken to a few friends who gave explanations : I must only use windows 
calls etc. However, I have to have my low-level stuff for the PV100 and still
make a DLL. 

Any advice or suggestions are greatly appreciated.

Thanks 
 Lindsay
