Hi All

I have decided to implement a little autosave function into my application that is used for datacapturing, but for some reason I am having some trouble.

Example...

Let's say I have three fields that text data can be stored in: txtfield1, txtfield2, and txtfield3.
I also have a seperate btn(bntSave) that when clicked, writes the entered data to the specifics I want it to.

Also add a text box(txtSaveName) used to specify the filename if desired.

Now, the event for the button would look something like this:

(Toggle Plain Text)

private void btnSave1_Click(object sender, EventArgs e)
        {
            StreamWriter write1 = new StreamWriter 
            ( "C:\\" + txtSaveName.Text );

            write1.WriteLine(txtfield1.Text);
            write1.WriteLine(txtfield2.Text);
            write1.WriteLine(txtfield3.Text);

            write1.Close();
         }

Now let's say I want the program to autosave using a timer, can I do the following?

(Toggle Plain Text)

private void timer_Tick(object sender, EventArgs e)
     {
            DateTime autosave = DateTime.Today;
            if (txtSaveName.Visible == true)
            {
                StreamWriter write1 = new StreamWriter
                ("C:\\" + "Auto Saved" + txtSaveName.Text);

            write1.WriteLine(txtfield1.Text);
            write1.WriteLine(txtfield2.Text);
            write1.WriteLine(txtfield3.Text);

            write1.Close();
            }
      }

Or is there an easier way of calling the event for "btnSave"?
My reason for asking is that I have about 90 or so fields that I am working with, so I would like to keep my code clean.

I have tried something similar and it only saved when I minimized the application's window or when I exited, where I wanted it to save more often, but not sure how to activate the autosave function with the timer?

Should I rather let it autosave for, when example, a field is being left, by implementing it's leave event?

All help will be much appreciated.

Thanks
