Q: Problems with VB and Delphi using a VB-ActiveX

Hello,
    yesterday we tried to test an ActiveX in Delphi 4.02 which was written
in  VB (6.0).

We encounterd a strange  phenomenon:

- We imported the tlb and compiled it to a new package -> ok
- designed a from with the ActiveXs -> ok
- setting/getting properties at the ActiveX -> ok
- using events of the ActiveX ->ok

- call any of the method -> BOOM
- making a latebound variable of myObject->ControlInterface and call the
methods -> OK

Anybody having an idea what going on ?

with best regards and greetings from Cologne
    Chris

(items() as variant)

Hello,

If you have the VB source, you should be able to debug it from the VB IDE
while Delphi is hosting the control.

have fun

I've got the *exact* same problem! Glad to know I'm not alone!

Haven't tried this yet. I guess I'll try tonight and see what it does.
