I have changed my non-visual component source which used to inherit from TComponent to TWinControl, and installed it so that it appears in the ActiveX Wizard. I've used the Wizard to create the ActiveX, but when I try to Register or install the ActiveX, I get the following error: " Incompatible Types: 'IStrings' and 'TStrings' " This is because the actual type is TStrings, but the wrapper method uses IStrings. How can I overcome this error? Thanks. -- Sam Back to top Sam Guest Posted: Thu Oct 09, 2003 6:45 am    Post subject: Re: IStrings and TStrings Hi, Thanks for the tip. I am a newbie. How do I use the TStringsAdapter? Do u mean change the 'IStrings' to 'TStringsAdapter'? Is that compatible with DAX? I just tried doing that, but gives the same error! -- Sam "Ignacio Vazquez" <ivazquezATorioncommunications.com> wrote Quote: Hello, Sam!
