I have successfully built a two column report in MS-Access (2013, if that matters). What I can't seem to find out, is how to get a separator line between the columns.
I have tried to draw a vertical line in the details area, but this is not working when some fields in the detail area can grow. The line does not grow, and there doesn't seem to be a "grow" option for lines.
What am I missing? If MS-Access does not offer this, is there a way to do this programmatically?
I think your easiest solution is to create an image - about the size of your page - with a vertical line in the middle, then use that image as a page background for your report.
From my experience, the best quality/wheight you can get is when your image is in the EMF (enhanced Meta file) format, a Microsoft vector format.
This is not supported by many tools. I use Inkscape (free) when I need that. And from my limited experience, (free) Inkscape gives better results than (expensive) Illustrator for that use case.
Alternatively, you can create such background image as a Word document, save to PDF, then find an online PDF to EMF converter.
