Hi guru ! I'm searching for a way to set a property at runtime of an COM Object. a bit like i can do with a TObject descendant using the RTTI if IsPublishedProp(Button1, 'Caption') then SetStrProp(Button1, 'Caption', 'test'); COM := CreateOleObject('XfoComCtl.XfoObj') COM is an interface OleVariant I know that is posible to retreive property cause the TLB importer and some application like COM Inspector do it. I want to be able to set the property by it name. Also, i dont want to import the TLB. i want to be independant of any version change of the COM object. thanks Patrick Back to top Marc Rohloff [TeamB] Guest Posted: Thu Jul 13, 2006 11:34 pm    Post subject: Re: Retreive and Set property of a COM Object.

If your library supports a dual com interface then you can use the methods of the IDispatch interface to retrieve type information. You can enable type information (RTTI) for interfaces by using the {$M+} directive but I don't know if this will help in your case.
