A system providing improved methods for remote method invocation of a service is described. The system includes methodology for a client to cast, at design time, a generic interface class to a remote service having a defined interface. The generic interface class dynamically generates a proxy for making a remote method call on the remote service at runtime, while also providing for runtime type checking. The generic interface class is subclassed to provide support for particular wire formats and methods of transport. The dynamically generated proxy converts a remote method call by the client into a wire format specified in the remote service's interface definition and calls the remote service using the method of transport specified in the interface definition. The system also supports making a service available to remote clients and includes modules for converting remote method calls on a service into native format.

Development system providing extensible remoting architecture

A system and methods for rapidly incorporating changes to a project is described. An object derived from a frame component container is embedded into a project, with the frame component container being freely changeable as desired. Any changes made to the frame component container are automatically included, by inheritance, into the source files of the project. Preferably, the method synchronizes on a display all instances of the object derived from the frame component container to the frame component container. The development system includes a computer and an interface for creating frame objects having components. Software permits the creation of descendant frame objects from an ancestor frame, propagation of modifications of the ancestor frame to each descendant frame object, notification of the descendant frame objects that its corresponding ancestor frame has been modified, and synchronization on a display of all of the descendant frames with any modifications to the components of the ancestor frame.

Frame component container

A visual development system is described which allows a user to derive forms from other 'ancestor' forms, inheriting their components, properties, and code as a starting point for one's own forms. During system operation, the user selects an 'Inherit' menu choice for indicating to the system that the form to be created inherits from an existing ancestor form. Ancestor forms can be any forms already contained in an existing project or in an 'object repository' provided by the system. Form inheritance allows the user to create a library of standard form templates, either within a single application or across an entire suite of applications. Any changes made to the ancestor form immediately appear in the descendant forms. Further, the use can customize each form type so derived while still retaining the ability to modify the standard form and have those changes reflected in the derived forms.
