[SOLVED] Automatic insertion of a value in the program

Automatic insertion of a value in the program

I need to periodically record a value in the program using a dialog box. The program is written in Borland Delphi 7, Windows API. The recorded value is stored in RAM.

I have a Java program that generates these values.

How do I modify the Java program so that the dialog box is called automatically and the desired value is copied there (At least tell me roughly in which direction to move)?

P.S. i want to inject a value into a different program's dialog box.

Solution

Well, here is my two cents. Let's assume you're using AWT/Swing to build the UI. If you want to simulate user input into a dialog box from an external Java program, you can use the Java Robot class to imitate key presses and mouse actions.

Here's a basic example:


import java.awt.Robot;
import java.awt.event.KeyEvent;

public class AutoInput {

    public static void main(String[] args) throws Exception {
        Robot robot = new Robot();

        // Optional: wait for the dialog to appear
        Thread.sleep(2000);

        // Type the number "42"
        robot.keyPress(KeyEvent.VK_4);
        robot.keyRelease(KeyEvent.VK_4);

        robot.keyPress(KeyEvent.VK_2);
        robot.keyRelease(KeyEvent.VK_2);

        // Press ENTER to confirm
        robot.keyPress(KeyEvent.VK_ENTER);
        robot.keyRelease(KeyEvent.VK_ENTER);
    }
}

If you want to change your code and automatically show a dialog and auto-fill a value and auto-confirm it (simulate the "OK" button press), use something like:

import javax.swing.*;
import java.awt.event.*;

public class AutoSubmitDialog {
    public static void main(String[] args) {
        JTextField field = new JTextField("42");

        JDialog dialog = new JDialog();
        dialog.setTitle("Set Parameter");

        JButton okButton = new JButton("OK");
        okButton.addActionListener(e -> {
            String value = field.getText();
            System.out.println("Submitted: " + value);
            dialog.dispose();
        });

        JPanel panel = new JPanel();
        panel.add(new JLabel("Enter value:"));
        panel.add(field);
        panel.add(okButton);

        dialog.add(panel);
        dialog.pack();
        dialog.setLocationRelativeTo(null);
        dialog.setVisible(true);

        // Automatically click OK after 2 seconds
        Timer timer = new Timer(2000, e -> okButton.doClick());
        timer.setRepeats(false);
        timer.start();
    }
}

This opens a dialog with a pre-filled value ("42") and simulates clicking "OK" after 2 seconds using Timer.

Maybe I misunderstood your exact goal, but I hope this points you in the right direction as requested :)

There is a caveat though that Java - being platform agnostic - has to rely on the platform here. There may be restrictions in place that may limit the robot's functionality. Read more about this in the documentation.
