If the target understands the native rendering mechanism and format of the object, it may be possible to render the object without any involvement on the part of the source, provided the source has given the target sufficient information to do so. In order for the rendering to be performed by the target, the source must fill in, at a minimum, the hstrContainerName and hstrSourceName fields. The hstrContainerName field represents the subdirectory that the file indicated by hstrSourceName is in. For the target to do the rendering on its own, the true type of the object must be DTYP_OS2FILE. When these conditions are met, the target may proceed with the operation. When the operation is complete, the target must send a DM_ENDCONVERSATION message to the window indicated by hwndItem in the DRAGITEM data structure.
