A container application is an application that can incorporate embedded or linked items into its own documents. The documents managed by a container application must be able to store and display OLE items as well as their own data. A container application must also allow users to insert new items or edit existing ones.
In this tutorial you will create a simple OLE container application, Container. The Container document can hold several in-place items that the user can resize and move in the document.
