I am not able to find how i can highlight a particular line of code in program listings.
Syntax highlighting seems to work but I dont need particular language keywords to be highlighted.

e.g.
for the code below how can i highlight/bold face char j=malloc......line

public static void function(){

    int i=0;

    char j = malloc(sizeof(char));

    /.......some code....

    return;

}

Like this:

documentclass[12pt]{article}

usepackage{listings}

usepackage{xcolor}



newcommand{hilight}{makebox[0pt][l]{%

    color{yellow}rule[-4pt]{0.65linewidth}{14pt}}%

}





begin{document}



begin{lstlisting}[language=C,escapechar=%]

public static void function(){

    int i=0;

    %hilight%char j = malloc(sizeof(char));

    /.......some code....

    return;

}

end{lstlisting}



end{document}

You can see the result on writeLaTeX.

To achieve the same result in LyX, go to Document->Settings and navigate to the Preamble tab. Paste everything from usepackage{listings} to the end of the begin{document} block into the preamble and save it.

To insert the program listing into the document, go to Insert -> Program Listing in the menu. Paste the code into the listing environment. Then hold Ctrl and right-click on the environment and open the Settings dialog. Go to the Advanced tab in the dialog and paste escapechar={%} into the text area. Configure the other settings however you want them to look.

There is an example LyX file you can download [here]
