How to suppress page number?

I've made myself custom title-page, put it in separate .tex file and when I input it, it is numbered with 1. The very next page is numbered with 1 also, and page-number increases on the following pages. Main file looks like this

\documentclass[11pt,a4paper,draft]{article}
\usepackage{./mystyle}

\begin{document}
\thispagestyle{empty}
\input{./titlepage.tex}
\input{./text.tex}
...
\end{document}

How do I suppress page-number on that title-page? (Why \thispagestyle{empty} doesn't work?) edit: Here's the title-page:

\begin{titlepage}
\begin{center}

% Upper part of the page
\textsc{\large Uni}\\[0.1cm]
\textsc{\Large Faculty}\\[2.8cm]
\textsc{\Large Sensors}\\[0.1cm]
{\Large Paper}\\[0.25cm]

% Title
\HRule \\[0.3cm]
{ \Large \bfseries Occupancy}\\[0.3cm]
{ \huge \bfseries Tribos}\\[0.05cm]
\HRule \\[0.05cm]

% Author and supervisor
\begin{center} \large
\emph{Student:}\\
An \textsc{Ant}
\end{center}
\vspace{1.8cm}
\begin{spacing}{0}
\tableofcontents
\end{spacing}
\vfill
% Bottom of the page
{\large \today}

\end{center}
\end{titlepage}

Did you try \pagestyle{empty}? –  Yiannis Lazarides Dec 18 '10 at 18:56
@Yiannis Lazarides As a matter of fact, it actually did turn of page-numbering, but I was unable to return it afterwards. –  user1996 Dec 18 '10 at 19:16
@everyone_with_same_problem: this fixed the problem - 1. add \pagenumbering{gobble} before title input 2. add \pagenumbering{arabic} after title input 3. add \pagestyle{empty} inside titlepage.tex. This could probably be generalized. –  user1996 Dec 18 '10 at 19:32

You could use \pagenumbering{gobble} to switch off page numbering.

To switch it on afterwards, use \pagenumbering{arabic} for arabic numbers or alph, Alph, roman, or Roman for lowercase resp. uppercase alphabetic resp. Roman numbering.

I'm using \pagenumbering{gobble}, but I'm having some problems with "already used pagenumber", I'm getting the warning message destination with the same identifier (name{page.}) has been already used, duplicate ignored<to be read again>... and it seems to be complaining on the second page in the document. How can I fix that? I'm also using the hyperref package. –  StrawberryFieldsForever Apr 26 '13 at 13:50
