 *
 * Remarks:
 * If a column is added to a list-view control with index 0 (the leftmost column)
 * and with LVCFMT_RIGHT or LVCFMT_CENTER specified, the text is not right-aligned
 * or centered. The text in the index 0 column is left-aligned. Therefore if you
 * keep inserting columns with index 0, the text in all columns are left-aligned.
 * If you want the first column to be right-aligned or centered you can make a dummy
 * column, then insert one or more columns with index 1 or higher and specify the
 * alignment you require. Finally delete the dummy column.
