MTM_DragCanAutoStart

Replaces SAM_DragCanAutoStart.
This message is sent to a table to ask whether it wants auto dragging.

Parameters
wParam
Position of the mouse on the X axis.
lParam
Position of the mouse on the Y axis.

Return
Return TRUE to enable auto dragging. If you do not process this message or you return FALSE, then M!Table does not enable auto dragging.

Remarks
When a table is subclassed with MTblSubClass( ), SAM_DragCanAutoStart doesn't work correctly anymore.
Therefore M!Table sends MTM_DragCanAutoStart so that you are able to use auto dragging.
