RE: [DUG]: Interface question

[Conor Boyd]

Hi Matthew,   Your Set_Items method is expecting a reference to an interface (IDataSightVariable).  You're passing it a string ('MyValue') in the example you gave.  The example you gave about creating an interface and setting the property values is therefore the expected behaviour.   Do you want to give a bit more code for us to have a look at?   Cheers,   Conor     -----Original Message----- From: Matthew Evans [mailto:[EMAIL PROTECTED]]   Here's my problem, I have a property that returns an interface. The interface has several properties. I can read these properties fine showmessage(Items[i].MyProp); for example. However if I want to set said interface property I can't. Items[i].MyProp:= 'MyValue'; will not call the set method. So the only way I can set Interface values is first create an interface set the property values then assign it to the items list items[i]:= MyInterface; Only been playing with these for a small amount of time and wondering how I should be going about this so I can read and write the interface properties right off the list? Any takers.   function Get_Items(Index: Integer): IDataSightVariable; safecall; procedure Set_Items(Index: Integer; const Value: IDataSightVariable); safecall; property Items[Index: Integer]: IDataSightVariable read Get_Items write Set_Items;
