Can you place somewhere your modified version?
Or send me by email?

Hi,
Sorry for late response because I'm working on another project and didn't
visit swt newsgroup for a while.
I have to say that I'm not a COM expert, so the solution maybe not perfect,
it's just for your reference. If you find errors or another good solution,
please let me know. thanks.
By the way, actually I rewrote the CDsoFramerControl(ActiveX control) by
using ATL and kept the CDsoDocObject(ActiveX document container), in that
way, I have integrate our system(COM based) with eclipse, and it works fine.
