Definition File Dialog
This dialog asks for the location of a COM definition file for the project. A COM definition file is either an IDL file or a Type Library. An IDL file is usually provided when building a new component since all the sources are available. However, when it comes to accessing an existing component, the sources might not be available. A Type Library is often embedded into the component and includes enough information for the wizard to generate the code.
The wizard accepts the following type extensions: idl, tlb, ocx, olb, dll, and exe.
The destination folder is the directory where the wizard saves generated files. The directory should be empty. If the wizard were to overwrite an existing file it would first back it up and emit a warning message. If any of the entered values are not correct when the Next button is pressed the wizard displays a warning message.
