EssGBeginRemoveOnly

Begins a remove-only operation, isolating the cells to be removed.

Syntax

ESSG_FUNC_M EssGBeginRemoveOnly (hGrid, usCells, pRemoveCells, ulOptions);

Parameter	Data Type	Description
hGrid	ESSG_HGRID_T	Handle passed back from EssGNewGrid.
usCells	ESSG_USHORT_T	A count of the number of cell ranges in pRemoveCells (the size of array).
pRemoveCells	ESSG_RANGE_T	Describes the cells to be removed. The members removed applies only to one dimension. That is, if the user decides to remove, for example, "Qtr1", then all other members of the Time dimension will be kept. All other dimensions in the report will be left untouched. This is a one-dimensional array of cell ranges. More than one member from a dimension may be specified. Also, multiple dimensions may be specified.
ulOptions	ESSG_ULONG_T	Reserved for future use. Should be set to zero.

Notes

The cells to be removed are described by a one-dimensional array of cell ranges. Items to be removed apply on a per dimension basis.

Return Value

If successful, returns ESSG_STS_NOERR.
