How to run reg file in Java Netbeans Code

Question

Please help me to solve : how to run .reg file in java netbeans ? And how to set source file automatically if I open the program in different computer ?

I have an reg file like this :

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\USBSTOR]
"Start"=dword:00000004

And this is my Java Code :

/**
 * Creates new form Form_DisableEnable
 */
public Form_DisableEnable() {
    initComponents();

    Dimension x = Toolkit.getDefaultToolkit().getScreenSize();
    Dimension y = getSize();
    setLocation(
    (x.width - y.width)/2,
    (x.height - y.height)/2);
}

/**

 * regenerated by the Form Editor.

Try this to import registry file:

Desktop.getDesktop().open(new File("c:/file.reg"));

If the file is in a jar, then you would probably need to write it to a temporary file and open that file instead.

EDIT:

Try something similar to the following snippet to load registry file, copy it to a temp file and then open temp file using default registry editor:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    loadRegFile("/resource/disable.reg");
}

public void loadRegFile(String filePath){
    try {
        //create temp file
        File temp = File.createTempFile("temp", ".reg");
        temp.deleteOnExit();

        BufferedWriter out = new BufferedWriter(new FileWriter(temp));

        //load an appropriate registry file
        InputStream in = getClass().getResourceAsStream(filePath);
        //copy to temp file
        IOUtils.copy(in,out); 
        out.close();

        //open using regedit
        Desktop.getDesktop().open(temp);
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}
