Setting the amount of lines on a page

[steven8579]

when i print the items in my listboxes it just keeps going and when it gets to the end of the page, it justs cuts off the rest. how do i get it to go to the next page. This is the code i have

private void docPrint_PrintPage(object sender, PrintPageEventArgs e)
         {
             float linesPerPage = 0;
             float yPos = 0;
             float xPos = 0;
             int count = 0;
             float leftMargin = e.MarginBounds.Left;
             float topMargin = e.MarginBounds.Top;
             string line = null;
             string line2 = null;
             m_objFont = new Font("Arial", 12);


             // Calculate the number of lines per page.
             linesPerPage = e.MarginBounds.Height /
             m_objFont.GetHeight(e.Graphics);

             // Print each line of the file.
             foreach (Control objControl in this.Controls)
             {
                 if (objControl.GetType().Name != "Button" && objControl.GetType().Name != "MenuStrip" && objControl.Name != "lblItemName" && objControl.Name != "lblItemValue" )
                 {
                     line = objControl.Text;

                     switch (objControl.Name)
                     {
                         case "lblSum":
                             e.Graphics.DrawRectangle(Pens.Black, lblSum.Location.X + leftMargin, lblSum.Location.Y + topMargin - 4, lblSum.Width, lblSum.Height);
                             m_objFont = objControl.Font;
                             break;

                         default:
                             m_objFont = objControl.Font;
                             m_objFont = new Font("Arial", 12);
                             break;

                     }
                     xPos = leftMargin + objControl.Location.X;
                     yPos = topMargin + objControl.Location.Y;
                    
                     e.Graphics.DrawString(line, m_objFont, Brushes.Black, xPos, yPos);
                 }
             }

             

             while (count < linesPerPage && nextItem < lstResult.Items.Count && nextItem < lstResult.Items.Count)

                 line = lstResult.Items[nextItem].ToString();
                 line2 = lstResult2.Items[nextItem].ToString();

                 e.Graphics.DrawString(line, m_objFont, Brushes.Black,

Have a look at MSDN tutorial - http://msdn.microsoft.com/en-us/library/system.drawing.printing.printdocument(v=VS.90).aspx

[steven8579]

I looked at the tutorial but i still dont know why it doesnt go to the next page. my code is in the first post

[steven8579]

any help would be appreciated

[ddanbe]

Perhaps this thread?

You could have found it yourself ;)

[steven8579]

i looked at that thread that you posted but its still unclear to me whats wrong with my code.

[ddanbe]

Then you shold give a clear explanation of what exactly is still unclair to you.

[steven8579]

in the if/else statement

//If more lines exist, print another page.                    
 if (nextItem < lstResult.Items.Count - 1 && nextItem < lstResult2.Items.Count - 1) 
    e.HasMorePages = true;       
 else                    
 {                        
   e.HasMorePages = false;                    
     nextItem = 0;     
 }

when i use this i dont get the next page. when i used what it said in the other thread, i get an infinate number of pages. i dont know what to put to make it so that it doesnt go on for an infinate number of pages.

[steven8579]

lstResult and lstResult2 are listboxes btw

[steven8579]

i tried changing the code to what was on the other thread but it just results in an infinate number of pages

[steven8579]

does anyone know whats wrong with this code? i dont want it to run on endlessly without going to the next page.

[kvprajapati]

1. Do not reset nextItem variable.

2. Want set top margin then set height of document.

float topMargin = e.MarginBounds.Top + 200;

linesPerPage = (e.MarginBounds.Height - 200) / m_objFont.GetHeight(e.Graphics);

 while (count < linesPerPage && linesprinted < totallines)
          {
         yPos = topMargin  + (count * m_objFont.GetHeight(e.Graphics));
         ....
          }

Have a look at sample app.

                e.HasMorePages = true;
            else
                e.HasMorePages = false;

        }
