CB_GETCOUNT Overview  Group

An application sends a CB_GETCOUNT message to retrieve the number of items in the list box of a combo box.

CB_GETCOUNT 

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

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

 

Parameters

This message has no parameters.

Return Values

The return value is the number of items in the list box. If an error occurs, it is CB_ERR.

Remarks

The index is zero-based, so the returned count is one greater than the index value of the last item.
