This message is sent by an application to determine the height of list items or the selection field in a combo box.

Syntax

CB_GETITEMHEIGHT
    wParam = (WPARAM) iIndex;
  lParam = 0;

Parameters

  • iIndex
    Specifies the component of the combo box for which to retrieve the height.

    This parameter must be set to -1 to retrieve the height of the selection field. It can be set to any other value to retrieve the height of list items, unless the combo box has the CBS_OWNERDRAWVARIABLE style. In that case, iIndex is the zero-based index of a specific list item.

  • lParam
    Not used.

Return Value

The height, in pixels, of the list items in a combo box indicates success. If the combo box has the CBS_OWNERDRAWVARIABLE style, it is the height of the item specified by the iIndex parameter. If iIndex is -1, 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.
