Thanks for your information!

I found the following in the header file in the dir :
the headerfile is scomm32.h
and I also have a scomm32.lib
so I can build a dll to overcome the struct difficulties,
but I want to try it out in VFP!!

#pragma pack(push, 1)

and in the end off the headerfile

#pragma pack(pop)

I read somewhere that this is depending off the /Zp switch in the
compiler.

best regards
