Look at COleSafeAray. You can create a 1 dimensional byte array COleSafeArray::CreateOneDim
copy your structure byte-per-byte into the array, then get the VARIANT out of the array using ColeSafeArray::Detach()
. You now have your structure in a VARIANT, which can be marshalled by both COM & DCOM. Also you have to free the memory allocated manually (since you called Detach()); call VariantClear() to do the job.
