View source for BM AUTOSIZE

This message causes a button to be resized based on the size of its contents.

==Syntax==
<PRE>
param1
     ULONG  ulReserved  /*  Reserved value, should be 0. */

param2
     ULONG  ulReserved  /*  Reserved value, should be 0. */

</PRE>

==Parameters==
;ulReserved (ULONG)
:Reserved value, should be 0. 

;ulReserved (ULONG)
:Reserved value, should be 0. 

==Returns==
;rc (BOOL)
:Success indicator.
:;TRUE
::The button was automatically sized according to the size of its contents. 
:;FALSE
::The button was not automatically sized. 

==Remarks==
This message is used by the notebook control to size buttons placed in the common area. If the button control has a style of BS_NOTEBOOKBUTTON, it responds to this message by setting rc as appropriate. If the button has any other style, the button control takes no action other than to set rc to FALSE.

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