The COM standard allows software components written in different languages to communicate with each other. However, building COM compliant applications requires the development of a large amount of "plumbing" code dedicated to supporting the technology. The EiffelCOM wizard was designed to free Eiffel developers from having to write the plumbing code.
The EiffelCOM wizard is a powerful tool that enables both the rapid development of COM components in Eiffel and the access of COM components from Eiffel systems. The wizard consists of a series of input fields, in which you describe the component's characteristics. The wizard uses data you enter to produce:

The wizard generates code from a Type Library and additional information given by the user. The generated code consists of Eiffel classes, C/C++ files, and library files. The wizard automatically produces library files from generated C and C++ code. You do not need to modify generated C/C++ code to build your EiffelCOM system.
{{note|The '''EiffelCOM Wizard''' is delivered with EiffelStudio, but it is a '''standalone tool''' (i. e., not part of the EiffelStudio IDE). You can find the wizard by following the directory path: ''$ISE_EIFFEL\wizards\com''. The executable file ''com_wizard_launcher.exe'' will launch the GUI version of the wizard. The executable file ''com_wizard.exe'' is a command line version of the wizard described [[Wizards: Command Line Options|here]].}}

The wizard can automatically compile the generated C and Eiffel code. To produce a Type Library corresponding to a given IDL file the wizard relies on '''MIDL''', the Microsoft IDL compiler. You may also provide the wizard with a Type Library directly. The wizard can also be used to add a COM interface to an existing Eiffel project. For the rest of the manual a '''COM Definition File''' will refer to the input file given to the wizard (either an IDL file, a Type Library or an Eiffel project file).
