In this post I will show you how make events to menu

1. Goto Toolbox and drag and drop a TabControl

2. We need a plain tabb. Because right click on middle of the tabb and select Delete

4. Click on tabb and go to Propeties -> Dock -> Fill

5. Double click on the New submenu and enter this codes

               TabPage tp = new TabPage("New");
               RichTextBox rtb = new RichTextBox();

               tp.Controls.Add(rtb);
               tabControl1.TabPages.Add(tp);
       

6. You have to make a new function for text box. here we are using RichTextbox
7. This is code for it

        private RichTextBox GetRichBox()
        {
            RichTextBox rtb = null;
            TabPage tp = tabControl1.SelectedTab;
            if(tp!=null)
            {
                rtb = tp.Controls[0] as RichTextBox;
            }
            return rtb;
        }
    


Now let's code the others

8. Double click on the submenu item and enter following codes

Open

OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "Text File(*.txt)|*.txt";
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                System.IO.StreamReader sr = new System.IO.StreamReader(ofd.FileName);
                GetRichBox().Text = sr.ReadToEnd();
                sr.Close();
            }

Save

SaveFileDialog sfd = new SaveFileDialog();
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                System.IO.StreamWriter sw = new System.IO.StreamWriter(sfd.FileName);
                sw.Write(GetRichBox().Text);
                sw.Close();
            }
        

Exit

Application.Exit();
        

Undo

GetRichBox().Undo();

Redo

GetRichBox().Redo();

Cut

GetRichBox().Cut();

Copy

GetRichBox().Copy();

Paste

GetRichBox().Paste();

Select All

GetRichBox().selectAll();

9. We can add a filter when open and save a text file.
10. To do this add following code to Open and Save submenus

Open

ofd.Filter="Text File(*.txt)|*.txt";
            

Save

sfd.Filter="Text Files(*.txt)|*.txt";
            

You can see when the programm is openning there was no new tabb. To make that we can make a new function by using code we use for New menu. So make a new function and call it when programm is open . Follow the following image guids

import java.sql.*;
import javax.swing.*;

• Now add following codes in to your method

Connection conn=null;
    public static Connection Connect(){
        
        try{
           String host="jdbc:derby://localhost:3306/blog";
