A project consists of containers and items. Some items are also containers, and contain other items. The IMpoProjectItemContainer interface maintains the relationship between a container and the items it contains.
For Visual Basic projects, the repository root object is modified to support this interface. The project items that are contained by the repository root object are projects. So the IMpoProjectItemContainer interface maintains the relationship between a repository and the projects that it contains.
Use the IMpoProjectItemContainer interface to determine the set of project items that are contained within a project item container. For Visual Basic projects, use this interface to determine the set of projects that are contained within a repository.
