It's not only about "the lines". I'll need to draw lines, text, use
colors, drag-'n-drop and much more. The problem is that I'm not even
completely aware about WHAT I'll need, but I'm sure that what I know
now, isn't half of it. Therefore I need more than a simple "draw a line"

No, I downloaded it from
http://gladewin32.sourceforge.net/modules/news/, which is the link from
the cairo site (which is, on a side note, a great place to get lost ...)

My idea is to write a simple module which gives a VB programmer access
to all the functions. Shouldn't be that hard, just a lot of work.
Only thing I haven't figured out is how to create the "cairo_t" object
in VB ... Oh, and ofcourse try to understand the LGPL license, which is
even harder for me...
Jonathan: thanks for the link, I'll check that out, too.
