I have a component (derived from TComponent) made with BCB 3.0 that do
some serial port communications, so it doesn't  need to be visible at
runtime. How can I make it an OCX?

 thanks in advance,
       Joao Paulo Faria

You need to declare the misc status flags with the invisible at runtime
setting. I don't have BCB 3 but in BCB 4, there is a macro that you insert
into your ocx class (after you use the wizard: File | New | ActiveX Tab |
ActiveX control). The ocx class is the TYourOCXImpl class that's in
YourOCX.h. In that class, add this macro in a public section:

  DECLARE_OLEMISC_FLAGS(dwDefaultControlMiscFlags |
OLEMISC_INVISIBLEATRUNTIME);

OLEMISC_INVISIBLEATRUNTIME is defined in oleidl.h.

Or, just make a simple in-place ActiveX automation object. (same as old OLE
automation object)
