[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 also have a Java program in JavaFX that generates these values for insertion, and its code is open for modification.

How can I modify a Java program so that the dialog box of the Delphi program is called automatically, and the desired value is also automatically copied there?

Well, or somehow find out where the necessary values are stored in memory and change them, bypassing the interface?

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.
