How wrap lines while print?

Sep 29 2004 3:18 PM
Hi, first of all sorry for bad english.. In this article http://www.c-sharpcorner.com/winforms/texteditor.asp I found a very useful way to print without use cristalreport. Now, my only problem is: if i have a string very long, this routine print the text out of the paper... (go out of right margin) In wich way can i wrap the text ?? My routine use readline function, so i think to insert every x char a \r special char... This works but is not good, infact "x i" use less space of "x o".... This is a portion of my code: string strText = ""; .. .. // what i want print strText = "bla bla bla \r \r \r"; strText = strText + "this is a very long line, more of the right margin"; strText = strText + "bla bla bla" myReader = new StringReader(strText); PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog(); printPreviewDialog1.Document = this.ThePrintDocument ; printPreviewDialog1.FormBorderStyle = FormBorderStyle.Fixed3D ; printPreviewDialog1.ShowDialog(); } .. .. private void ThePrintDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs { float linesPerPage = 0; float yPosition = 0; int count = 0; float leftMargin = ev.MarginBounds.Left; float topMargin = ev.MarginBounds.Top; string line = null; Font printFont = this.txtcognome.Font; SolidBrush myBrush = new SolidBrush(Color.Black); linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics); // Leggo riga per riga tutto quello che voglio stampare while(count < linesPerPage && ((line=myReader.ReadLine()) != null)) { yPosition = topMargin + (count * printFont.GetHeight(ev.Graphics)); ev.Graphics.DrawString(line, printFont, myBrush, leftMargin, yPosition, new StringFormat()); count++; } if(line != null) ev.HasMorePages = true; else ev.HasMorePages = false; myBrush.Dispose(); } } and this is my not good routine used to split long lines of text: void splitta(string nota1) { int i = 0; int cr = 0; while(i < nota1.Length) { if (((cr > caratteri) & (nota1.Substring(i,1) == " ")) || (cr > caratteri)) { Console.Out.WriteLine ("Stacco all'elemento: "+nota1.Substring(i,1)+" in posizione: "+cr ); nota1 = nota1.Insert(i, "\r"); cr=0; } cr++; i++; } strText = strText + nota1; } the only way to use this routine well, is to use "Courier new" form..but this is not good solution.. (in courier new every char has the same width) Con u solve my problem (or pheraps exist a free report tool ?) ? (i dont have a crystal report license) Sorry for long message.. i hope u help me
