LB_SETITEMHEIGHT message

Sets the height, in pixels, of items in a list box. If the list box has the LBS_OWNERDRAWVARIABLE style, this message sets the height of the item specified by the wParam parameter. Otherwise, this message sets the height of all items in the list box.

Parameters

wParam

Specifies the zero-based index of the item in the list box. Use this parameter only if the list box has the LBS_OWNERDRAWVARIABLE style; otherwise, set it to zero.

Windows 95/Windows 98/Windows Millennium Edition (Windows Me) : 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 list box is limited only by available memory.

lParam

Specifies the height, in pixels, of the item. The maximum height is 255 pixels.

Return value

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