auto saving the text in text editor every five seconds

Question

I am new to C#. Basically I want to implement an auto save function using a timer. May I know how do I have to implement it, so that the text will get saved automatically every 5 seconds?

SaveFileDialog saveFile1 = new SaveFileDialog();

saveFile1.DefaultExt = "*.rtf";
saveFile1.Filter = "RTF Files|*.rtf";

if (saveFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK &&
           saveFile1.FileName.Length > 0)
{

   txtb.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);

I can save the file but how do I auto save it?

Write a method that saves the file without user interaction, i.e. without a `SaveFileDialog`, then call that method from your manual save routine, i.e. the `Click` event handler of the appropriate `Button`, and from your auto save routine, i.e. the `Tick` event handler of your `Timer`. There's no magic to it. — jmcilhinney, Mar 26 '18 at 03:32

Just use a timer with an interval of 5000ms

Timer tmr = New Timer;
tmr.Interval = 5000;

Now call your timer in the Form_Load event or whereever you want to call it the first time. After that, just use the Tick event of the timer (Note: The first time you call the SAVEFILEDIALOG, make sure that you store the location in some variable so that you can keep on reusing it to save the text file which will eliminate the need of using the SAVEFILEDIALOG again and again):

String pathOfFile;

private sub FirstTimeSaveIt_Click // the button that saves it first
if (saveFile1.ShowDialog() == System.Windows.Forms.DialogResult.OK &&
saveFile1.FileName.Length > 0)
{
  pathOfFile = saveFile1.FileName
  txtb.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);
  }
private void tmr_Tick()
{
tmr.Stop();
txtb.SaveFile(pathOfFile, RichTextBoxStreamType.PlainText);

tmr.start();
}

Just declare the event in ur form load – Software Dev Mar 26 '18 at 07:05
private void File_Save_MenuItem_Click(object sender, EventArgs e) { Timer tmr = new Timer(); tmr.Interval = 5000; tmr.Start(); //logic to save tmr.Stop(); tmr.Tick += File_Save_MenuItem_Click; } is the way i have done is correct – Ema_wat Mar 26 '18 at 07:10

System.Windows.Forms.Timer tmr = new System.Windows.Forms.Timer(); i used this instead of declaring namespace . – Ema_wat Mar 26 '18 at 07:55
