Return code	Description
S_OK	Success.
E_POINTER	A parameter contained an invalid pointer.

Remarks

This method deletes all of the strokes in the InkDisp object if no InkStrokes collection is passed in. To delete only one stroke at a time, call the DeleteStroke method.

The InkDisp object renumbers the indices of the remaining strokes in the InkDisp object if the strokes that were deleted do not fall at the end of the InkDisp object's collection of strokes.

Note  The contents of a InkStrokes collection become invalid when strokes that are contained in the collection are deleted from the InkDisp object.

 

DeleteStrokes can result in an error if called while the user is actively laying down ink.
