CB_SETITEMHEIGHT message

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

Parameters

wParam

Specifies the component of the combo box for which to set the height.

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

lParam

Specifies the height, in pixels, of the combo box component identified by wParam.

Return value

If the index or height is invalid, the return value is CB_ERR.

Remarks

The selection field height in a combo box is set independently of the height of the list items. An application must ensure that the height of the selection field is not smaller than the height of a particular list item.
