accessing OLE events
|
|
| Christian K 2006-03-09, 8:24 pm |
| I'm attempting to add additional processing to an ActiveX control's
event. I was unable to utilitze any properties/methods/events when
implementing with the ActiveX class, as they were not visible or
defined.
However, when I invoke it thru OLE automation from the OleAutoClient
class, I can inspect the properties/methods/events, and access/call the
properties & methods. I'd now like to define a function to trigger for
specific events of the ActiveX, but have had no success. Everytime I
attempt to define a function for the event, it shows up as a seperate
user-defined method.
Anyone have any expereince in this area?
Cheers,
Christian K.

events in COM are one of the mysteries in this technology, at least to me.
I came to the conclusion, that they either work or not (duh), but there is
no real clue why they work or why the refuse to do.
I fear i cannot be of great help here...

Hmm, did you try to do it with a codeblock ?

| Marc,
Yeah, tried the codeblock, without luck. I get the impression that
these types of instances generally mean the ActiveX is using some VB
component which obviously dBase doesn't have. Thanks for the suggestion.
