    Default how to get return values from a button to main program.

    hello,

    I have a main program which has a button Authenticate. On click of authenticate open a form for auth which has USERNAME FIELS AND PASSWORD.
    If entered fields are true then enable editing of jtable in main program..

    Basically something like this :
    //main program
    Authenticate.addActionListener(new ActionListener()
    {
    public void actionPerformed(ActionEvent ae)
    {
    UpdateAuth ua=new UpdateAuth();// opens form which has username and pass for authentication
    ua.setVisible(true);

    //need code here for enabling table
    if(s=="mactus")
    {
    enable table editing
    }
    //table.repaint();
    }

    });


    // form open for auth..(class UpdateAuth )

    private String SigninMouseClicked(java.awt.event.MouseEvent evt) {
    String aname=Aname.getText();
    String apass=Apassword.getText();
    if(aname.equals("") && apass.equals(""))
    {
    JOptionPane.showMessageDialog(null,"Enter login name or password","Error",JOptionPane.ERROR_MESSAGE);
    }
    if(!(aname.equals("") && apass.equals("")))
    {
    if(aname.equals("harshil") && apass.equals("harshil123"))
    {
    String s="mactus"; /// if username and password is success enable table editing in main program
    return s;

    }
    else if (!aname.equals("mactus") && !apass.equals("mactus123"))
    {
    Aname.setText("");
    Apassword.setText("");
    }
    }
    return null;
    }

    Default Re: how to get return values from a button to main program.

    Can you explain what the problem with the code is?

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
