Adding to an OS Design
You can add to a Windows Embedded CE–based OS design by doing one of the following:
Insert a Catalog item from the Catalog
Insert a subproject using commands from the Project menu
Use a wizard to create a subproject
Files, such as those for audio and video, can be inserted into an OS design using the same approach as used for subprojects.
By default, when you create a subproject, or add a file, or Catalog item to an OS design, it is included in the final run-time image.
Also, the Catalog contains preexisting Windows Embedded CE Catalog items. You can extend the Catalog by creating and adding Catalog item (.pbcxml) files to the OS tree. Third-party functionality can also be imported into the Catalog.
