Columns control the way items and their subitems are displayed in report view. Each column has a title and width and is associated with a specific subitem. The attributes of a column are defined by an LVCOLUMN structure.
To add a column to a list view control, use the LVM_INSERTCOLUMN message. To delete a column, use the LVM_DELETECOLUMN message. You can retrieve and change the properties of an existing column by using the LVM_GETCOLUMN and LVM_SETCOLUMN messages. To retrieve or change a column's width, use the LVM_GETCOLUMNWIDTH and LVM_SETCOLUMNWIDTH messages.
Unless the LVS_NOCOLUMNHEADER window style is specified, column headers appear in report view. The user can click a column header, which causes the live view control to send an LVN_COLUMNCLICK notification message to the parent window. Typically, the parent window sorts the list view control by the specified column when the user clicks the column header.
List view controls can set the order in which columns are displayed. To implement this feature, specify the LVCF_ORDER value and assign the proper value to the iOrder member in the LVCOLUMN structure.
