Ok I did look into this package, but I doubt that I will be able to get this running. I am not have the root password and I am not clever enough to do it. But thx a lot for your help - even if I am not going to use this macro, it was very helpful. I have a similar problem with a package called "mcode" - I guess because of the same reason!
Thx again!

Yuchuu, that is doing the job

Code: Select all
\documentclass{article}
\usepackage{color}
\definecolor{mygrey}{gray}{0.80}
\newcommand{\resheading}[1]{{\large \colorbox{mygrey}{\begin{minipage}{\textwidth}{\textbf{#1 \vphantom{p\^{E}}}}\end{minipage}}}}
\begin{document}
\resheading{ihjkjhkjhjh}
\end{document}
