Whenever I type something in LaTeX and want to view it in PDF, it doesn't yield the required view, even if the file is saved. Instead it gives me an error stating that the file can't be found. Can anyone help me out with this problem? I've downloaded Texmaker for Windows.
Downloading of TeXMaker is not enough, because TeXMaker is only an editor (like Notepad, but smarter :) ). You must install MiKTex or TeXLive. These are TeX distributions, which means they provide the program (
pdflatex) to create a PDF from your LaTeX code (="source code").
This process is usually called "typesetting" and not "conversion to PDF".
When you have installed a TeX distribution, and created a TeX source (code) in your editor, you have to typeset it. (The editor can even be Notepad, but then you have to type stuff in the command line.) When you use TeXMaker, you can hit F1 to typeset, which (if I'm not mistaken) will create the PDF and open the PDF viewer. "Saving" the source does not create the PDF.
