What does your COM DLL do?

Hi,

I'm stuck with a problem I can't solve.
I have build an ActiveX DLL wich is registered (CreateOLE ) every times I
launch the app.
For some reason, the ActiveX runs without any problem on machines where
delphi is installed, but when I try to run the same DLL and EXE on a
machines without Delphi, I get errors (I can't even see what the errors
are).

Can someone help me with it, I think it has something to do with the
integrated de{*word*81} of delphi, I just can't figure why the same code, with
the same registration works on some computers and on others it doesn't.

Thanks in advance,

eldad

I found the problem

I had an IStrings interface that was not properly used.

This is the line that failed to work on computers without delphi :

GetOLEStrings (vValueObject.ItemsList as TStrings,vValueElement.FFixedItems)

The vValueElement.FFixedItems is a IStrings interface (nil).
For some reason, when I used this procedure on machines with delphi, no
error occured and string values were properly assigned to the interface, but
on other machines (without delphi)... error.

I changed it and added a function and a procedure to encapsulate a
TStringList with an IStrings, and it worked everywhere.

What I still wonder is, why didn't I get any error when I used it on delphi
machines ...

Must have been a latent bug. :(

have fun
