Up until now, I've just been using LyX for all my LaTeX needs. Now I have a
.tex file and I need to compile it (turn to pdf). How do I do this on Windows XP? Obviously I have LaTeX installed (MikTeX).
one way of doing this is using the command line by entering
pdflatex yourfilename.tex (assuming MikTex is in your path - just give it a try).
A third way could be to import it into LyX and then compile with LyX as usual.
