LB_SETCOUNT Overview  Group

An application sends an LB_SETCOUNT message to set the count of items in a list box created with the LBS_NODATA style and not created with the LBS_HASSTRINGS style.

LB_SETCOUNT 

wParam = (WPARAM) (int) cItems; // count of list box items 

lParam = 0;                     // not used; must be zero 

 

Parameters

cItems
Value of wParam. Specifies the new count of items in the list box.

Windows 95: The wParam parameter is limited to 16-bit values. This means list boxes cannot contain more than 32,767 items. Although the number of items is restricted, the total size in bytes of the items in a listbox is limited only by available memory.

Return Values

If an error occurs, the return value is LB_ERR. If there is insufficient memory to store the items, the return value is LB_ERRSPACE.

Remarks

The LB_SETCOUNT message is supported only by list boxes created with the LBS_NODATA style and not created with the LBS_HASSTRINGS style. All other list boxes return LB_ERR.
