[DUG] creating an ActiveX object

[Phil Middlemiss]

Well Phil, the thing you need to do is this:

- Descend your component from TCustomControl (or TWinControl) even 
though it is non-visual.
- Register it on the component pallete
- Create a new ActiveX library project
- Create a new ActiveX control based upon your component
- Modify the second to last parameter in the Factory.Create call (in the 
initialization section) to OLEMISC_INVISIBLEATRUNTIME
- Save and compile the project
- Select "Run|Register ActiveX Server".

Simple.

BTW, you could have worked this out if you had done a bit more searching 
on Google groups.

Phil.
