As far as I know, the only thing you need to do is create a class that
implements IDispatch. You hardly need a wizard for that, I think ?

Well, using Delphi 7 I click in 'New'>'ActiveX'>'Active Server Object'.
After type the "CoClass Name" -- TFooClass for example -- and choose
some parameters, the IDE creates:
1. An unit contents a pre-implementation of my class:
uses
 ComObj, ActiveX, AspTlb, Project1_TLB, StdVcl;
type
 TFooClass = class(TASPObject, IFooClass)
 protected
   procedure OnEndPage; safecall;
   procedure OnStartPage(const AScriptingContext: IUnknown); safecall;
 end;

2. A file like "project_TLB.pas" that have, between others things:
 IFooClass = interface;
 IFooClassDisp = dispinterface;
...
 CoFooClass = class
   class function Create: IFooClass;
   class function CreateRemote(const MachineName: string): IFooClass;
 end;
...
class function CoFooClass.Create: IFooClass;
begin
 Result := CreateComObject(CLASS_FooClass) as IFooClass;
end;

class function CoFooClass.CreateRemote(const MachineName: string): IFooClass;
begin
 Result := CreateRemoteComObject(MachineName, CLASS_FooClass) as IFooClass;
end;

3. An "wizard" to insert new methods to simplify, I think, and a
"Text" is created on demand like that:
FooClass = coclass(IFooClass [default] )
 [ uuid '{E984E6AF-C43A-4B34-BF96-E03B43AC6A3E}',
   version 1.0,
   helpstring 'FooClass Object' ];

But I don't know if is relevant... anyway.


So, how an new FPC programer should know these things to make a ActiveX?

By studying ActiveX maybe ?

I could be wrong, but I don't think just implement IDispatch is enough, do you?

Maybe I was a bit short on details in my reply :-)

Yes, you can of course write a wizard that does all this. It's just generating text, after all.

Michael.
