Delete all rows and columns of the listview control in Win32 SDK

You can use the Win32 SDK to delete all rows of the listview control by sending messages, with all columns:

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 );
