Know how many lines or space are left until the end of the page in MS-Word

I need to know, when I insert text into a word document, how many lines or space I have left until I reach the bottom of the page.
My problem is that I am writing records (a bold title and lines of text) from a database. Sometimes, a title remains on the current page and the text on the next one. And I want to prevent this from happening, by inserting a page break. To perform this page break, I must know how much space or lines I have left before the end of the page.
Is there any way to know how many lines or how much space is left until the end of the page?
Best regards.
Don't try something very complicated (and unnecessary) like 'counting how much space or lines are left before the end of the page'. The definition that you need is in the 'paragraph' palette - in the 'line and page breaks' window, there is an option called 'keep with next'. This option will bump the chosen line (the title) to the next page if there is not enough room on the same page for the text which belongs to the title.
In a macro, it looks like Selection.ParagraphFormat.KeepWithNext = True

Best way to align center a paragraph with RestructuredText?

What is the best way to have a paragraph align in the center of the page using restructuredText for pdf (rst2pdf)?
You can use the following:
.. class:: center
This paragraph will be centered.
If you want to use center tag (as described above) on rst2html.py (Docutils 0.12), you should create a css file, namely mystyle.css by adding the following line to it:
.center {text-align: center;}
For converting your rst file, namely, myrst.rst to html file, use the following command
rst2html myrst.rst myrst.html --stylesheet=mystyle.css,html4css1.css
By using this method, the following code works well.
.. class:: center
This paragraph will be centered.

TCPDF for setting margins

I am generating PDF file using TCPDF, when I try to use inbuilt functions for setting margin, i.e. $pdf->SetMargins(), it doesn't work. My main purpose for it to remove extra space for ul and li tags, because it is disturbing my pdf format and text content mixing into each other.
Any help would be appreciated.
Set margins is for the document itself and it will not affect the ul or lis on the document. You got to set the styling for those yourself. One tip is to do the styling all inline (just pretend that you building up a page for 1990).

Ruby/Rails - Properly Display/Format Text From The Text Area Form Control

I have a interesting problem. I have a :text field in my model with displays a large chunk of data, usually about three paragraphs.
When I enter the text in on the new view it might look like....
aaaaaaaaaaaaaaaaaaaaaaaaa.
bbbbbbbbbbbbbbbbbbbbbbbbbbbb.
ccccccccccccccccccccc.
Imagining that each a,b, or c is an individual paragraph.
With a space between the a, b, and c lines....(e.g. the line break that occurs when you press enter)
But when I display the very same data on the view, the line breaks are not recognized. The view seems to concatenate all the text into one big blurb and it displays like.....
aaaaaaaaaaaaaaaaaaaaaaaaa.bbbbbbbbbbbbbbbbbbbbbbbbbbbb.ccccccccccccccccccccc.
But the line breaks are being recorded because going to edit shows the data in the format with the line breaks.
I thought about adding < p >'s into the text area and parsing the html on the view but that really isn't a good option since I dont want to require my users to insert html tags.
Is there something I'm missing to get the text area to display in the same fashion as it was entered?
Try simpleformat:
<%= simple_format(my_text_from_database) %>
