Report with columns. How to get lines that precisely overlap

rbuser

I am displaying a grid on a report using a report with columns and a
Tppshape rectangle in the detail band that is the full size of the band.
This grid must fix the paper size chosen by the user, so I set the height
and width in the beforeprint event of the report.

The problem is that frequently what should be coincident grid lines (right
of one cell and left of next cell) do not precisely coincide and I get
double lines. This would seem to be a rounding problem in the dimensions of
the report.

What is the best way to avoid this and produce "clean" lines? And given it
has to fit the user chosen page I can not just experiment an find a fixed
layout that works.

Is this in the previewer or on the printer? The previewer will not match
your printed output.

Article: Why Your Preview Won't Match Your Output
-----------------------------------------------------

We have two choices when we create a preview - compose for the screen, or
compose for the printer. Most programs such as MS Word compose to the screen
when they create a preview. This makes for attractive previews but they tend
to
be inaccurate. And it means that they then compose again for the printer
when you print the document. Most of the time things will print effectively
similar to the preview, but we have seen many times when the printed output
was different - a word wrapped to the next line, or some such problem. If
you use a program meant for accurate page layout, such as PageMaker, you
will notice that the Page Setup dialog asks you for which printer you wish
to compose. When PageMaker displays a page, it may not look exactly how
you think it should, but you do get a preview where the element placement
is guaranteed to match the printed output's element placement.
We have chosen to follow this second model.

Note that when we say element placement, we are referring to X and Y
placement and not height and width. While the X and Y placement of
our previews will be accurate, the height and width of text elements
may vary based on zoom percentage. This is a normal artifact of
composing for the printer and not for the screen.

Your preview can not match your printed output. It will
differ in one of two ways:

1- It can look good on the screen, but items on the page may not
display in the same location they will when printed.
or
2- It can be less attractive, but items will display on the preview
exactly where they will when printed.

We give you the second because it is more accurate and more reliable.
Not to mention more in keeping with professional page layout products.
