Problem with automatic bibliography [closed]

I have the need to get the bibliography of a latex document in an automatic way. I'm trying since two weeks. Here is my code:

\usepackage{multirow}
\usepackage{epstopdf}
%\graphicspath{immagini}
\usepackage{booktabs}
%\providecommand{\abs}[1]{\big|#1\big|}
\usepackage{caption}
%\usepackage {table}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{amsmath}
\usepackage{pict2e}
\usepackage{amssymb}
\usepackage{amstext}
\usepackage{txfonts}
\usepackage{setspace}
\onehalfspacing
\usepackage{textcomp}
\newenvironment{sistema}
{\left\lbrace\begin{array}{@{}l@{}}}
{\end{array}\right.}
\usepackage{indentfirst}
\usepackage{geometry}
\geometry{a4paper,top=3cm,bottom=3cm,left=4.5cm,right=2.5cm,heightrounded,bindingoffset=5mm}
\usepackage{fancyhdr}

%\usepackage{thebibliography}

\usepackage{biblatex}
\usepackage[babel]{csquotes}
%\cleardoublepage
%\phantomsection
\printbibliography
\bibliography{biblio.bib}
%\printbibliography

\end{document}


The bibliography doesn't show in any way. My editor is Worktex. I compile with pdfLaTeX, BibTeX and again pdfLaTeX twice but without any result: the compilation ends well but in the resulting PDF there's no bibliography. I would appreciate any help. Obviously I created the biblio.bib file.

ehm...this is an English forum, not an Italian one. If you prefer the latter, please visit the guit forum. ehm...questo è un forum inglese, non italiano. Se ne preferisci uno italiano, visita il forum del guit –  Spike Jul 7 '12 at 10:31
@Spike: You could salvage this question if you translated it to English. Then we could reopen it. But only if you want. –  doncherry Jul 7 '12 at 11:21
i'm so sorry. i've just sent my main file in tex. i use the texwork editor and i'm in troubles with the automatic latex bibliography. i created my .bib file but i can't visualize the biblio in the pdf. someone could tell me exactly which commands or packages i'm supposed to use.. AND WHERE TO PUT EM IN THE MAIN FILE. thank u –  user16357 Jul 7 '12 at 14:58
@doncherry added the translation. I haven't deleted the italian part, your choice if this is needed. user16357 see my answer. It works (guarda la mia riposta. Il codice proposto funziona) –  Spike Jul 7 '12 at 15:18

You misplace the \printbibliography command. You have to put it in the position where you need to show the bibliography. The following example work:

\documentclass{book}

\usepackage{multirow}
\usepackage{epstopdf}
%\graphicspath{immagini}
\usepackage{booktabs}
%\providecommand{\abs}[1]{\big|#1\big|}
\usepackage{caption}
%\usepackage {table}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{amsmath}
\usepackage{pict2e}
\usepackage{amssymb}
\usepackage{amstext}
\usepackage{txfonts}
\usepackage{setspace}
\onehalfspacing
\usepackage{textcomp}
\newenvironment{sistema}
{\left\lbrace\begin{array}{@{}l@{}}}
{\end{array}\right.}
\usepackage{indentfirst}
\usepackage{geometry}
\geometry{a4paper,top=3cm,bottom=3cm,left=4.5cm,right=2.5cm,heightrounded,bindingoffset=5mm}
\usepackage{fancyhdr}

%\usepackage{thebibliography}
\usepackage[babel]{csquotes}
\usepackage{biblatex}
%\cleardoublepage
%\phantomsection

\bibliography{biblio.bib}
%\printbibliography

%
\begin{document}
%********************
%\include{frontespizio}
%**************************

\frontmatter

%***************************
%\include{dedica} %DEVI MODIFICARLA
%\include{Ringraziamenti}
%********************
\tableofcontents %SOMMARIO
%**************
\mainmatter
%**************
%\input{chapter1_introduzione}
%\input{chapter2}
%\input{chapter3}
%\input{chapter4}
%\input{chapter5}
%\input{chapter6}
%\input{chapter7}
%\input{chapter8}
%
%*****************

\nocite{*}
\printbibliography

\end{document}


I assumed you use the book document class because you use the \frontmatter (etc..) command. I also switched the position of the csquotes and the biblatex package, as explained in the documentations.

I'm not sure if we tolerate question without any sign of English. However: since we tend to improve the codes in questions in other ways than just solving the problem, I would suggest using cases or dcases instead of user-defined sistema. The environment dcases needs mathtools package. –  yo' Jul 7 '12 at 11:05
