[Tex/LaTex] How to change a font document wide

fontssans-serif

How do I change a font for a latex document?

I am using the \documentclass{article}, which sets the document in a serif font.
I also declared \usepackage{helvet}, since that's the font I would like to use as a sans-serif.
But how do I get latex to actually set the document in a sans-serif font?

Also, I am using the package lslisting to format code-listings.
How can I set my document such that all code is set in a separate font, e.g. courier or any other typewriter font?

You want to change the default family to be the sans serif family.

\renewcommand\familydefault{\sfdefault}

does exactly that.

Concerning your other question,

\lstset{basicstyle=\ttfamily}

make all code to be typeset in the active typewriter family, which is by default Computer Modern Typewriter. You can change that to Courier with \usepackage{courier}, just as you select Helvetica for the sans family with \usepackage{helvet}.

\renewcommand{\familydefault}{\sfdefault} will switch to using sans-serif for everything except mathematics. The sans-serif will be computer modern sans unless you also put \usepackage{helvet} in the preamble in order to make the default sans be Helvetica (or \usepackage{avant} for Avant-Garde, etc.

If I understand your question correctly, you are trying to get a document typeset using a sans-serif font rather than the "ordinary" serif font. In addition, you want the font that's used in math to be upright rather than "slanted". The only math font I'm familiar with that's upright rather than slanted is the so-called "Euler" font; it goes reasonably well with Computer Modern fonts, both serif and sans-serif. If the Euler font suits your needs, you should add the following commands to the preamble of your document:

\renewcommand{\encodingdefault}{T1}
\usepackage[T1]{fontenc}
\renewcommand{\familydefault}{\sfdefault}
\usepackage{eulervm}
