1. Code to get progress bar in the slides:
\usepackage{tikz}
\usetikzlibrary{calc}
\definecolor{pbblue}{HTML}{0A75A8}% filling color for the progress bar
\definecolor{pbgray}{HTML}{575757}% background color for the progress bar
\makeatletter
\def\progressbar@progressbar{} % the progress bar
\newcount\progressbar@tmpcounta% auxiliary counter
\newcount\progressbar@tmpcountb% auxiliary counter
\newdimen\progressbar@pbht %progressbar height
\newdimen\progressbar@pbwd %progressbar width
\newdimen\progressbar@tmpdim % auxiliary dimension
\progressbar@pbwd=\linewidth
\progressbar@pbht=1.5ex
% the progress bar
\def\progressbar@progressbar{%
\progressbar@tmpcounta=\insertframenumber
\progressbar@tmpcountb=\inserttotalframenumber
\progressbar@tmpdim=\progressbar@pbwd
\multiply\progressbar@tmpdim by \progressbar@tmpcounta
\divide\progressbar@tmpdim by \progressbar@tmpcountb
\begin{tikzpicture}[rounded corners=2pt,very thin]
\shade[top color=pbgray!20,bottom color=pbgray!20,middle color=pbgray!50]
(0pt, 0pt) rectangle ++ (\progressbar@pbwd, \progressbar@pbht);
\shade[draw=pbblue,top color=pbblue!50,bottom color=pbblue!50,middle color=pbblue] %
(0pt, 0pt) rectangle ++ (\progressbar@tmpdim, \progressbar@pbht);
\draw[color=normal text.fg!50]
(0pt, 0pt) rectangle (\progressbar@pbwd, \progressbar@pbht)
node[pos=0.5,color=normal text.fg] {\textnormal{%
\pgfmathparse{\insertframenumber*100/\inserttotalframenumber}%
\pgfmathprintnumber[fixed,precision=2]{\pgfmathresult}\,\%%
}%
};
\end{tikzpicture}%
}
\addtobeamertemplate{headline}{}
{%
\begin{beamercolorbox}[wd=\paperwidth,ht=4ex,center,dp=1ex]{white}%
\progressbar@progressbar%
\end{beamercolorbox}%
}
\makeatother
2. Code to get the number of slides:
\setbeamertemplate{navigation symbols}
{\Large\color{red}\bf \insertframenumber/\inserttotalframenumber }
3. Code to get Table of Contents before each section:
\AtBeginSection[]
{
\begin{frame}{Table of Contents}
