I'm using the Filenet Watermark component to develop an apps. I had imported the ActiveX component in Delphi so I can use them on my form. I can access all the method of the object except for that,... 2 properties of the are of IDispatch type. Those are Image and Document. I must use some method in those sub-objects, but I cannot access them. CodeInsigth show me only the IDispatch method but not the other.

You need to create an OleVariant, and set this variant equal to the IDispatch properties.  This will convert the variant to type VT_IDISPATCH, which is a variant type of a pointer to an IDispatch interface.  You will then be able to use the variant as you would an object to access it's methods and properties.  This also works for IUnknown interfaces as well.
