Container items can be anything that your application or a user might store in a container. Examples are executable programs, word processing files, graphic images, and database records.

Container item data is stored in the RECORDCORE and MINIRECORDCORE data structures. Both the application and the container have access to the data stored in these records.

The application must allocate memory for each record by using the CM_ALLOCRECORD message.

The maximum number of records is limited only by the amount of memory in the user's computer. The container control does not limit the number of records that a container can have.
