Sheet Element Selection
Many sheet properties, functions, and methods perform actions on a cell, a range of cells, a column, a row, or the entire sheet. Before using these properties, functions, and methods, you must often select or specify the element for which you want to specify characteristics.
DLL users specify the cell, column, row, or spreadsheet as parameters of functions. ActiveX users set the Col and Row properties to identify the coordinates of a cell, the column number, the row number, or the entire sheet, as explained in Using Column and Row Properties and Working with Selected Cells.
