Retrieves the column and row number for the cell with the specified index.
Parameter |
Description |
nCellIndex |
A zero-based index of the cell for which to get the position. |
puRow |
Pointer to a variable to be updated with the vertical position (row) of the specified cell. Row numbering starts with 1. |
puCol |
Pointer to a variable to be updated with the horizontal position (column) of the specified cell. Column numbering starts with 1. |
uFlags |
Reserved for future use. Pass 0. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. To get extended error information, call GetLastError, and refer to Return Codes. |
The row and column numbers obtained by this function are relative to the first cell in the container.
