How To Customize Registry File In Netbeans
Preview
Hello friends, in this post I will discuss about Registry in Windows Operating System. The Registry is a hierarchically arranged database that supports information about the configuration of a system from hardware, software to user preferences. So later we will read, add and remove registry in Registry Editor
In the picture above I have a sub folder with the name of Tutorial in HKEY_CURRENT_USER folder, in that folder we will process the registry using form in Netbeans.
First open Netbeans and create a new project and add "some" components in the form including one jTextField and three jButtons.
If done, import some librabry we need
import javax.swing.JOptionPane;
import ca.beq.util.win32.registry.RegistryException;
import ca.beq.util.win32.registry.RegistryKey;
import ca.beq.util.win32.registry.RegistryValue;
import ca.beq.util.win32.registry.RootKey;
import ca.beq.util.win32.registry.ValueType;
Then, double-click jButton1 and enter the code to add a registry in accordance with the contents of jTextField1

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt){
try{
RegistryKey r = new RegistryKey(RootKey.HKCU,"Tutorial");
RegistryValue v = new RegistryValue(jTextField1.getText(), ValueType.REG_SZ, "Your Value");
JOptionPane.showMessageDialog(null, "Registry Added");
r.setValue(v);
}catch(Exception e){
JOptionPane.showMessageDialog(null, e);
}
}
Next, double-click jButton2 and enter the code to read the registry, whether existing or not in accordance with the contents of jTextField1.
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt){
try{
RegistryKey r = new RegistryKey(RootKey.HKCU,"Tutorial");
if(r.hasValue(jTextField1.getText()){
JOptionPane.showMessageDialog(null, "Registry Already");
}
else{
JOptionPane.showMessageDialog(null, "Registry Not Found");
}
}catch(Exception e){
JOptionPane.showMessageDialog(null, e);
}
}
And finally double-click jButton3 and enter the code to delete the registry in accordance with the contents of jTextField1
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt){
try{
RegistryKey r = new RegistryKey(RootKey.HKCU,"Tutorial");
RegistryValue v = new RegistryValue(jTextField1.getText(), ValueType.REG_SZ, "Your Value");
JOptionPane.showMessageDialog(null, "Registry Deleted");
r.deleteValue(jTextField1.getText());
}catch(Exception e){
JOptionPane.showMessageDialog(null, e);
}
}
When done and there is no error, the program is ready to run.
