{{DISPLAYTITLE:LM_SETITEMHEIGHT}}
This message sets the height of the items in a list box.

==Syntax==
<pre>
param1
ULONG flNewHeight; /* Height of items in list box. */

param2
ULONG ulReserved;  /* Reserved value, should be 0. */
</pre>

==Parameters==
;flNewHeight ([[ULONG]]) - input: Height of items in list box.
;ulReserved ([[ULONG]]) - input: Reserved value, should be 0.

==Returns==
;rc ([[BOOL]]) - return: Success indicator.
::TRUE: Successful operation.
::FALSE: Error occurred.

==Remarks==
The list box control window procedure responds to this message by setting the
height of the items in a list box to that specified by '''flNewHeight'''.

This message does '''not''' send a [[WM_MEASUREITEM]] message.

==Default Processing==
The default window procedure does not expect to receive this message and
therefore takes no action on it, other than to set '''rc''' to the default value of FALSE.
