View source for WM QUERYBORDERSIZE

This message is sent to the frame window to determine the width and height of the border of the window.
==Syntax==
<PRE>
param1
PWPOINT pSize;     /* Width and height of size border control. */

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

==Parameters==
;pSize (P[[WPOINT]]) - Output
: Pointer to a [[POINTL]] structure that is used to hold the width in the '''x''' parameter and the height in the '''y''' parameter.
;ulReserved ([[ULONG]]) - Input
: Reserved value, should be 0.

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

==Remarks==
The frame window responds to this message by returning the width and height of its border in the '''pSize''' parameter, as follows:
* SV_CX/CYSIZEBORDER if FCF_SIZEBORDER is specified
* SV_CX/CYDLGFRAME if FCF_DLGBORDER is specified
* SV_CX/CYBORDER if FS_BORDER is specified.

==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.
