Methods

columnExtent()

Returns the number of columns occupied by this cell accessible. The result is greater than 1 if the specified cell spans multiple columns.

[propget] HRESULT columnExtent(
  [out] long nColumnsSpanned
);

Parameters

nColumnsSpanned

Returns the 1 based column extent of the specified cell.

Return value

S_OK.

columnHeaderCells()

Returns the column headers as an array of cell accessibles.

[propget] HRESULT columnHeaderCells(
  [out, size_is(, nColumnHeaderCells,)] IUnknown cellAccessibles,
  [out] long nColumnHeaderCells
);

Parameters

cellAccessibles

Pointer to an array of references to cell accessibles. The array is allocated by the server. Free it with CoTaskMemFree.

nColumnHeaderCells

The number of accessibles returned; the size of the returned array.

Return value

S_FALSE if there is no header, [out] values are null and 0 respectively. S_OK.

columnIndex()

Translates this cell accessible into the corresponding column index.

[propget] HRESULT columnIndex(
  [out] long columnIndex
);

Parameters

columnIndex

Returns the 0 based column index of the cell of the specified cell or the index of the first column if the cell spans multiple columns.

Return value

S_OK.

isSelected()

Returns a boolean value indicating whether this cell is selected.

[propget] HRESULT isSelected(
  [out] boolean isSelected
);

Parameters

isSelected

Returns true if the specified cell is selected and false otherwise.

Return value

S_OK.

rowColumnExtents()

Gets the row and column indexes and extents of this cell accessible and whether or not it is selected. This is a convenience function. It is not mandatory to implement it.

[propget] HRESULT rowColumnExtents(
  [out] long row,
  [out] long column,
  [out] long rowExtents,
  [out] long columnExtents,
  [out] boolean isSelected
);

Parameters

row

0 based row index.

column

0 based column index.

rowExtents

Number of cells spanned by this cell in this row.

columnExtents

Number of cells spanned by this cell in this column.

isSelected

Indicates if the specified cell is selected.

Return value

S_OK.

rowExtent()

Returns the number of rows occupied by this cell accessible.

[propget] HRESULT rowExtent(
  [out] long nRowsSpanned
);

Parameters

nRowsSpanned

Returns the row extent of the specified cell.

Return value

S_OK.

rowHeaderCells()

Returns the row headers as an array of cell accessibles.

[propget] HRESULT rowHeaderCells(
  [out, size_is(, nRowHeaderCells,)] IUnknown cellAccessibles,
  [out] long nRowHeaderCells
);

Parameters

cellAccessibles

Pointer to an array of references to cell accessibles. The array is allocated by the server. Free it with CoTaskMemFree.

nRowHeaderCells

The number of accessibles returned; the size of the returned array.

Return value

S_FALSE if there is no header, [out] values are null and 0 respectively. S_OK.

rowIndex()

Translates this cell accessible into the corresponding row index.

[propget] HRESULT rowIndex(
  [out] long rowIndex
);

Parameters

rowIndex

Returns the 0 based row index of the specified cell or the index of the first row if the cell spans multiple rows.

Return value

S_OK.

table()

Returns a reference to the accessbile of the containing table.

[propget] HRESULT table(
  [out] IUnknown table
);

Parameters

table

Returns a reference to the IUnknown of the containing table.

Return value

S_OK.
