Solution 1

Change this:

C#

BackUpTimer.Interval = Convert.ToInt32(2000);

To this:

C#

BackUpTimer.Interval = Convert.ToInt32(2000 * 60);

not working

phil.o 13-Feb-20 3:03am

What does 'not working' mean? Interval is expressed as a number of millisecconds, so when you specify 2000ms it means 2s. And nothing is done on tick of the timer, or you didn't show it.
Please, help us to help you and provide much more sensible informations than a generic 'not working'.

OriginalGriff 13-Feb-20 3:32am

"It doesn't work" is probably the most useless problem report we get - and we get it a lot. It tells us nothing about what is happening, or when it happens.
So tell us what it is doing that you didn't expect, or not doing that you did.
Tell us what you did to get it to happen.
Tell us any error messages.

phil.o 13-Feb-20 3:05am

Convert.ToInt32(2000 * 60)

Hum... :)

OriginalGriff 13-Feb-20 3:14am

Yeah ... I think the OP is a little out of his depth ...

Member 12386982 13-Feb-20 4:08am

sir...the control is not entering into backup class.. for editing the xml file... i want automatic editing.. plz help

phil.o 13-Feb-20 4:13am

Please see solution 2. Your event handler, or at least what you showed from it, does not do anything at the moment. Did you forget to use your Backup class in it?

OriginalGriff 13-Feb-20 4:16am

That still doesn't tell us anything!

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
So tell us how you know what is happening, what you have tried to do to find out why, what happened when you did. And stop trying to type as little as possible - it doesn;t help you and it doesn't help us. Unless you give us actual information to work with, all we can do is keep going "And? What happened?" and that wastes your time and ours.

Help us to help you!

sir, i want to run my application automatically after a particular time intervals like 2 minutes. and edit an xml file with current time. so i used a thread and a timer. i have created a form and a class ( backup.cs ).

//Code of Form
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Threading;
using Microsoft.Win32;

namespace AutoBackup
{
public partial class Form1 : Form
{
Backup objBackup = new Backup();
NotifyIcon notifyIcon = new NotifyIcon();
RegistryKey reg = Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunOnce", true);
public Form1()
{
reg.SetValue("DBTool", Application.ExecutablePath.ToString());
InitializeComponent();
Thread splashthread = new Thread(new ThreadStart(objBackup.backup));
splashthread.IsBackground = true;

try
{
//objBackup.IPAddress();
System.Timers.Timer BackUpTimer = new System.Timers.Timer();
BackUpTimer.Interval = Convert.ToInt32(2000 * 60 );
BackUpTimer.Elapsed += new System.Timers.ElapsedEventHandler(MyTimer_Elapsed);
BackUpTimer.Start();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
private void MyTimer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
objBackup.backup();
}

}
}

//Code of Backup Class
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;
using System.Xml;

namespace AutoBackup
{
public class Backup
{
string path = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
public void backup()
{
using (XmlWriter writer = XmlWriter.Create(path+"\\BackupDetails.xml"))
{
writer.WriteStartElement("Backups");
writer.WriteElementString("Time", DateTime.Now.ToString());
writer.WriteEndElement();
writer.Flush();
}
}
}
}

my problem is the control is not even entering into backup class while first time running. which i mentioned
Thread splashthread = new Thread(new ThreadStart(objBackup.backup));

OriginalGriff 13-Feb-20 4:43am

Of course it isn't - you haven't told it to!
You don't have a class constructor method, so creating a new Backup instance doesn't automatically execute any of your code, and your Thread is never started.

What does the debugger show is happening when your Elapsed handler is executed?

Member 12386982 13-Feb-20 4:58am

i changed the code of form like below.. so the control enter into the class..

public Form1()
{
reg.SetValue("DBTool", Application.ExecutablePath.ToString());
InitializeComponent();
Thread splashthread = new Thread(new ThreadStart(objBackup.backup));
splashthread.IsBackground = true;
splashthread.Start();

try
{
//objBackup.IPAddress();
System.Timers.Timer BackUpTimer = new System.Timers.Timer();
BackUpTimer.Interval = Convert.ToInt32(2000 * 60 );
BackUpTimer.Elapsed += new System.Timers.ElapsedEventHandler(MyTimer_Elapsed);
BackUpTimer.Start();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Member 12386982 13-Feb-20 5:01am

now i want to run the application automatically.. plz help..

OriginalGriff 13-Feb-20 5:08am

You're showing us the same stuff each time, you aren't telling us anything useful, or even new.

Take a step back, forget code. I am sat in front of my PC. I have installed your finished app and I know nothing about it. I have rebooted my PC, and I have a completely blank screen, except for the icon for your app on my desktop. What should I do now, and what should I expect to happen?

Member 12386982 13-Feb-20 5:25am

once you have installed my application, it will run automatically when you on your PC. and will automatically run after a particular interval of time and update an xml file (updating the current time).

https://drive.google.com/file/d/1XCyYkLf7pwb-mIb3WIAoT0t9cU6tYwGL/view?usp=sharing

the link contain my application

OriginalGriff 13-Feb-20 6:29am

You can't do that in your code!
To do that, you have to tell the operating system to either run your app at startup, or to run it at defined periods. You would add that functionality as part of your setup app, and it would probably require elevation to do it.
Your app can't start a timer and exit, expecting the timer to do something every two minutes despite your app no longer being running!

Member 12386982 13-Feb-20 22:36pm

how should i do that.

OriginalGriff 14-Feb-20 2:14am

What have you tried?

Member 12386982 14-Feb-20 3:24am

i dont know how to do.. i googled alot..

Member 12386982 15-Feb-20 2:16am

Plz help...

Solution 2

It might also be a good idea to actually call the backup routine in the

MyTimer_Elapsed

event handler.

e.g.

C#

Backup myBackup = new Backup();
myBackup.backup();

Your current event handler does nothing at the moment!
