CB_GETITEMHEIGHT

An application sends a CB_GETITEMHEIGHT message to determine the height of list items or the selection field in a combo box.

CB_GETITEMHEIGHT

wParam = (WPARAM) index; // item index

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

Parameters

index

Value of wParam. Specifies the combo box component whose height is to be retrieved.

This parameter must be pics/WIN3200090000.gif1 to retrieve the height of the selection field. It must be zero to retrieve the height of list items, unless the combo box has the CBS_OWNERDRAWVARIABLE style. In that case, the index parameter is the zero-based index of a specific list item.

Return Values

The return value is the height, in pixels, of the list items in a combo box. If the combo box has the CBS_OWNERDRAWVARIABLE style, it is is the height of the item specified by the index parameter. If index is pics/WIN3200090000.gif1, the return value is the height of the edit control (or static-text) portion of the combo box. If an error occurs, the return value is CB_ERR.
