This macro sets the virtual number of items in a virtual list-view control.
void ListView_SetItemCountEx( HWND hwndLV, int cItems, DWORD dwFlags );
Handle to a virtual list-view control.
Number of items that the list-view control will contain.
Specifies the behavior of the list-view control after resetting the item count. It can be one or a combination of the following values.
The list-view control will not repaint unless affected items are currently in view.
The list-view control will not change the scroll position when the item count changes.
This macro is intended only for list-view controls that use the LVS_OWNERDATA and LVS_REPORT or LVS_LIST styles.
If the list-view control was created with the LVS_OWNERDATA style, this macro sets the virtual number of items that the control contains.
If the list-view control was created without the LVS_OWNERDATA style, the ListView_SetItemCount macro should be used.
