# How to modify chapter name in headers in memoir

I modified the chapter title to be shown as 1. ..., but the headings still show CHAPTER. How can I remove the chapter in headings? Is there a way to modify the chapter style in the contents and heading at the same time?

\documentclass[12pt,oneside]{memoir}
\usepackage{lipsum}

\title{Document}
\author{prosseek}
% }

\makeatletter
\newcommand{\fonttitle}{\chaptitlefont}
\makechapterstyle{mystyle}{%
\def\chapterheadstart{\vspace*{\beforechapskip}}
\def\printchaptername{}
\def\printchapternum{}
\def\printchapternonum{}
\def\printchaptertitle##1{\fonttitle \space \fonttitle \thechapter.\space \fonttitle ##1}
\def\afterchaptertitle{\par\nobreak\vskip \afterchapskip}
}
\makeatother

\chapterstyle{mystyle}

\begin{document}

\maketitle
\tableofcontents

\chapter{The Domain Problem and Stakeholders}
\section{First}
\lipsum

\end{document}

Chapter styles and page styles are two separate things. You only changed the chapter style.

If the headings style is ok for you and you only want to remove CHAPTER then use

\addtopsmarks{headings}{}{
\createmark{chapter}{both}{shownumber}{}{. \ }
}
\pagestyle{headings}


You might want to consider adding \nouppercaseheads before \pagestyle{...}, this removes the uppercaseness of the headers.
