EiffelCOM Wizard

The third tutorial describes how to access a COM component. It will build a client of the StringManipulator component built in the first tutorial.

Step by step instructions

1. In Project, in the Current project input field, type in string_manipulator_client and press enter.
2. In Project Type, choose Access an existing COM component.

This chapter explains how to use the EiffelCOM wizard to create COM components and to access existing components.

• Creating a new COM component .
• Creating a new component from an Eiffel Project.
• Accessing a COM component.

{{Caution|EiffelCOM currently requires the use of the Microsoft C compiler (available with Visual Studio or the Microsoft Windows SDK).

The second tutorial describes creating a COM component from an Eiffel system. The tutorial example String is almost identical to StringManipulator of the previous tutorial. In the StringManipulator example the wizard starts from an IDL file and builds an Eiffel System; in contrast, the String example takes an Eiffel system and generates an IDL file and the required plumbing code to make the Eiffel project accessible to COM.

This first tutorial describes creating a COM component from a COM definition file that is either an IDL file or a Type Library. The tutorial focuses on creating an in-process (DLL) component, called StringManipulator.
