Hi,
I want to send a binary buffer within methods or events (or a pointer of a
buffer if possible) of an ocx.
Does ocxs in a single application uses the same virtual memory?
Kind regards,
Cagatay

The only safe way to do that in COM is to pass a SAFEARRAY of type VT_UI1

that has the desired bytes copied into it. Depending on your target
environments, you may or may not also need to wrap the SAFEARRAY inside a
VARIANT as well.
