Page Layout ⇒ Customize Header/footer for specific unumbered chapters

[viragiste]

Hi !
the problem is simple

i'm using SW 5.5, thesis shell new south wales,
ok i'm making a general introduction and a general conclusion .. assigned as chapters but unumbered !
that's why the header is still always that of the previous chapter ! so i added the command for theses pages :

Code: Select all

\thispagestyle{empty}

this is a sample of the code for the introduction :

Code: Select all

\chapter*{%
%TCIMACRO{\TeXButton{no header}{\thispagestyle{empty}}}%
%BeginExpansion
\thispagestyle{empty}%
%EndExpansion
Introduction g\'{e}n\'{e}rale%
%TCIMACRO{%
%\TeXButton{toc}{\addcontentsline{toc}{chapter}{Introduction générale}}}%
%BeginExpansion
\addcontentsline{toc}{chapter}{Introduction générale}%
%EndExpansion

now I want to make for these unumbered chapters custumized headers and footers with rules

note that the fncyhdr packages does not work since i'm using a predefined shell, nonetheless some command are still working like

Code: Select all

\rfoot{ENiM 2009}
\renewcommand{\footrulewidth}{0.5pt}
\pagenumbering{roman}

many thanks in advance
