Int Ncols;
Hwnd hwndlistview, hwndlistviewheader;
// Delete all rows
Sendmessage (hwndlistview, lvm_deleteallitems, 0 , 0 );
// Get the header form of listview
Hwndlistviewheader = (Hwnd) sendmessage (hwndlistview, lvm_getheader, 0 , 0 );
// Obtain the number of columns.
Ncols = Sendmessage (hwndlistviewheader, hdm_getitemcount, 0 , 0 );

Ncols -- ;
// Delete all columns
For (; Ncols > =   0 ; Ncols -- )
Sendmessage (hwndlistview, lvm_deletecolumn, ncols, 0 );
