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.
