Hallo,
from my understanding during the development of DLLs for VB there are
the following important things:
1. Compile with stdcall: VB uses the stdcall (Pascal) calling
convebtion. Either hardcode it (_I_ wouldn't do that) or use the -mrtd
with gcc.
2. When passing structs mind the sick padding convention in VB! They pad
to 4byte! So you have to fill by hand your c/c++-struct to contain a
multiple of 4bytes and compile with -fpack-struct.
NB: Additionally I compile with -fnative-struct. I found no
documentation for this option (Could anybody explain?) but it is used
for the gtk-port and sounds good to me :-)
Of course DllMainStartup... must be linked with the object files for the DLL
Best wishes,
Alexander.
