Printing student records: I want to show every record on a different page

around this issue You need to change the logic of your reads.
Place the reader outside of the PrintPage event and in it read and DrawString etc until the page is full or reader is empty. Then return from the event. It will be called again automatically if HasMorePages is true..
SqlDataReader dr = null;
PrintDocument pdoc = null;
int pageNr = 0;

private void printButton_Click(object sender, EventArgs e)
{
    // connect and open reader
    // ..
    // set up the print document..
    pdoc = new PrintDocument();
    pdoc.DocumentName = "Printer Test";
    pdoc.PrintPage += PrintDocument_PrintPage;
    // ..
    pageNr = 0;
    pdoc.Print();
    // close connection & reader..
}

private void PrintDocument_PrintPage(object sender, PrintPageEventArgs e)
{
    bool pageDone = false;
    pageNr++;
    if (pageNr > maxPage) return;  // optional

    while(dr.Read())
    {
        e.HasMorePages = true;  // we have more data
        // print stuff
        // ..
        // if each Read fills one page..:
        pageDone = true; // ..or else use condition like y > yMax
        if (pageDone) return;  // return to print next page
    }
}

This might help you Just add @review = Review.new to the show action on your venues controller. Then put the form right in your venue#show view file.
venues_controller.rb
def show
  @venue = Venue.find(params[:id])
  @review = Review.new
end

How can I list all records which belong to another record at the show page?

I wish this helpful for you First, can you show us your areas_controller.rb file please?
Inside your view you can do this by doing:
<% @area.venues.each do |venue| %>
  <%= venue.name %>
  # etc.
<% end %>
def show
  @area = Area.find(params[:id])
end
class Area < ActiveRecord::Base
  has_many :venues
end
class Venue < ActiveRecord::Base
  belongs_to :area
end

may help you . ok, so @plate.translations is the set of current translations that are already on the plate.
If you want a fields-for section for a new one... you have to actually build a new one.
<%= f.fields_for :translations, [@plate.translations.build] do |fff| %>
  <div>
    <%= fff.text_field :meaning %>
  </div><br><br>
<% end %>

How can I get my program back on track when printing out all student records?

wish of those help When you initialize the BinaryTreeArray(), you set the field variable "size" to 100 and use this to initialize the data Listing[] array. When you print out the data, the loop uses the same "size" variable so you get all 100 entries, including the null entries. A simple solution would be to filter the data for null when you show all.
public class BinaryTreeArray
{ 

  ...

  public void showAll()
  { 
      for(int i=0; i<size; i++)
      {
          if (data[i] != null)
              System.out.print(data[i] + " "); 
      }
  } 

  ...

}

load more records script show the same last record from a previous set of records if a new record is added

This might help you I'm very confused and I don't know how to solve this problem i'm not sure if I have to adjust the jQuery or the SQL to properly show this without duplicates. I just don't know, so I have this script that loads a set of records every time you press the load more button. , Your SQL query is correct but wrong for this situation.
SELECT*FROM records WHERE NOT status='remove' ORDER BY ID DESC LIMIT $start, $limit";
