using System.Drawing.Printing;

namespace Drucken
{
    public partial class Drucken : Form
    {
        public Drucken()
        {
            InitializeComponent();
        }
        private string[] lines;
        private int linesPrinted;
        string filename = "";

        private void button1_Click(object sender, EventArgs e)
        {

            
        }
        private void Form1_Load(object sender, System.EventArgs e)
        {                        
        }


        private void OnBeginPrint(object sender,
                          System.Drawing.Printing.PrintEventArgs e)
        {
            char[] param = { '\n' };

            if (printDialog1.PrinterSettings.PrintRange == PrintRange.Selection)
            {
                lines = richTextBox1.SelectedText.Split(param);
            }
            else
            {
                lines = richTextBox1.Text.Split(param);
            }

            int i = 0;
            char[] trimParam = { '\r' };
            foreach (string s in lines)
            {
                lines[i++] = s.TrimEnd(trimParam);
            }
        }
        // OnPrintPage

        private void OnPrintPage(object sender,
                                   System.Drawing.Printing.PrintPageEventArgs e)
        {
            int x = e.MarginBounds.Left;
            int y = e.MarginBounds.Top;
            Brush brush = new SolidBrush(richTextBox1.ForeColor);
           

            while (linesPrinted < lines.Length)
            {
                
                e.Graphics.DrawString(lines[linesPrinted++],
                     richTextBox1.Font, brush, x, y);
       
                y += 15;
                if (y >= e.MarginBounds.Bottom)
                {
                    e.HasMorePages = false;
                    return;
                }
                else
                {
                    e.HasMorePages = true;
                }
            }
        }

        private void richTextBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void button1_Click_1(object sender, EventArgs e)
        {
              PrintDialog pdlg = new PrintDialog();
            pdlg.Document = printDocument1;

            if (pdlg.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    printDocument1.Print();
                }
                catch (Exception ex)
                {
                    MessageBox.Show("Druken Fehlgeschlagen " + ex.Message);

                }
            }
        }        
        

        private void button2_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFile1 = new OpenFileDialog();

            openFile1.Filter = "To Write 2010(*.twt)|*.twt| Textdokument (*.txt)|*.txt| Word Dokument (*.doc)|*.doc";
            if (openFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK && openFile1.FileName.Length > 0)
            {
                richTextBox1.LoadFile(openFile1.FileName, RichTextBoxStreamType.UnicodePlainText);
                richTextBox1.LoadFile(openFile1.FileName, RichTextBoxStreamType.RichText);
                this.filename = openFile1.FileName;
            }
        }

        private void button3_Click(object sender, EventArgs e)
        {
            Close();
        }
    }
}
