2017年11月27日 C#MDI窗体创建记事本打印记事本查找、自动换行

MDI窗体第一个父窗体

把属性里的IsMdiContainer设置为true就可以了

父窗体连接子窗体

//创建一个新的类,用来连接别的窗体,并且别的窗体为唯一窗体

List<Form> F = new List<Form>();private void opendao(Form f){Form F1 = null;bool isopen = false;foreach(Form gf in F){gf.Hide();if(gf.Name == f.Name){isopen = true;F1 = gf;}}if (isopen){f.Close();F1.Show();}else{f.MdiParent = this;f.WindowState = FormWindowState.Maximized;f.Parent = panel1;f.FormBorderStyle = FormBorderStyle.None;f.Show();F.Add(f);}}

第一个按钮的连接或者别的也可以

       
//连接到第二个窗口private void button1_Click(object sender, EventArgs e){Form2 f2 = new Form2();f2.Name = "1";opendao(f2);}

第二个按钮连接或者别的也可以

//连接到第二个窗口   private void button2_Click(object sender, EventArgs e){Form3 f3 = new Form3();f3.Name = "2";opendao(f3);}

注:可以多个窗体连接只显示在父窗体里

 

记事本页面设置

 private void toolStripMenuItem1_Click(object sender, EventArgs e){pageSetupDialog1.Document = printDocument1;DialogResult dr = pageSetupDialog1.ShowDialog();if (dr == DialogResult.OK){}}

记事本打印

//注:第一个代码为绘画,将字符串绘画,重要!private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e){string s = textBox1.Text;Font f = new System.Drawing.Font("微软雅黑", 25.5f);Brush b = new SolidBrush(Color.Red);e.Graphics.DrawString(s, f, b, 20, 20);}//打印private void 打印PToolStripMenuItem_Click(object sender, EventArgs e){printDialog1.Document = printDocument1;DialogResult dr = printDialog1.ShowDialog();if (dr == DialogResult.OK){printDocument1.Print();}}

记事本打印预览

        private void 打印预览VToolStripMenuItem_Click(object sender, EventArgs e){printPreviewDialog1.Document = printDocument1;printPreviewDialog1.ShowDialog();}

记事本自动换行

  private void 自动换行ToolStripMenuItem_Click(object sender, EventArgs e){if (textBox1.WordWrap){//不自动换行textBox1.WordWrap = false;textBox1.ScrollBars = ScrollBars.Both;自动换行ToolStripMenuItem.Checked = false;}else{//自动换行textBox1.WordWrap = true;textBox1.ScrollBars = ScrollBars.Vertical;自动换行ToolStripMenuItem.Checked = true;}}

记事本新窗体查找

   
//此为第二个窗口的设置
         Form1 F1;public Form2(Form1 f1){InitializeComponent();F1 = f1;}int a = 0;private void button1_Click(object sender, EventArgs e){string s = textBox1.Text;a = F1.textBox1.Text.IndexOf(s, a + 1);if (a != -1){F1.textBox1.Select(a, s.Length);F1.textBox1.Focus();}else{MessageBox.Show("无匹配项！");}}

//此为第一个窗口使用private void 查找ToolStripMenuItem_Click(object sender, EventArgs e){Form2 f2 = new Form2(this);f2.Owner = this;f2.Show();}
