ActiveX data marshalling

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I am writing a component in Delphi to use in VB (don't ask - there are very
good reasons :-)

I need to send back from Delphi a potentially large amount of data (mail
attachments) up to 100mb and binary.

Currently this is being sent back as a Variant array of Byte which means
that on the receiving end in VB you are getting back an array with
potentially millions of elements.

It looks like the favourite mechanism is some form of Variant.

Given this, is there any particular type of Variant that would work well in
VB? Are there any particular restrictions?

thanks all,

jON
