You could use the literate key; in the following example. parentheses are typeset in red:

\documentclass{article}
\usepackage{listings} 
\usepackage{xcolor}

\lstset{
    basicstyle=\small\ttfamily,
    columns=fullflexible,
    literate=*{(}{{\textcolor{red}{(}}}{1}
         {)}{{\textcolor{red}{)}}}{1},
    }
\begin{document}

\begin{lstlisting}
    {
      _SetCalibTableName("lorem",100);
      g_Met_strReferenceName1=Met_strReferenceName;
    }
\end{lstlisting}

\end{document}

enter image description here

    Thanks. it works. just a question what is that number 1 in literate? it should be always 1? what happen if we change it?

    @Karo You're welcome. The last argument (the "1" in my example) specifies the width (in number of characters) that the replacement string (the colored parenthesis) will occupy in the output. Wider strings might require a larger value. Commented Jul 17, 2014 at 14:56
  • @GonzaloMedina I never understood that. For instance {…}{...}1 will output the same as {…}{...}3.

    @Manuel that is because fullflexible was used in my exmaple; try this \lstset{ basicstyle=\small\ttfamily, literate=*{(}{{\textcolor{red}{aa}}}{1} {)}{{\textcolor{red}{mmm}}}{1}, } and you'll see the difference. Commented Jul 17, 2014 at 15:15
  • @GonzaloMedina Ah, true. I use fullflexible too, so it has no meaning there.
