This message is sent by the container control to its owner when a pickup set is dropped over the container.
Syntax
param1 USHORT id; /* Container control ID. */ USHORT CN_DROPNOTIFY; /* Notification code. */ param2 PCNRLAZYDRAGINFO pCnrLazyDragInfo; /* Pointer to the CNRLAZYDRAGINFO structure. */
Parameters
- id (USHORT) - Input
- Container control ID.
- CN_DROPNOTIFY (USHORT) - Input
- Notification code.
- pCnrLazyDragInfo (PCNRLAZYDRAGINFO) - Input
- Pointer to the CNRLAZYDRAGINFO structure.
- This structure contains information about the DRAGINFO, the RECORDCORE that was dropped on, and the window handle of the target window.
Returns
- ulReserved (ULONG) - returns
- Reserved value, must be 0.
Remarks
This notification code is sent to the owner of the container when a lazy drag set is dropped over the container. (The container control receives a DM_DROP message.)
Default Processing
The default window procedure does not expect to receive this notification and so takes no action on it other than returning 0.
