how do I cause "Submit" to save a form to file location of my choi

[vegan gerry, chief software architect]

public void FormEvents_Submit(object sender, SubmitEventArgs e)
{
// If the submit operation is successful, set
// e.CancelableArgs.Cancel = false;
// Write your code here.
throw new Exception("Submit failed");
}

Above is the default submit event. I've added the "throw new Exception" for
now.

I would like to trap the .xml file that presumably would get written if it
were error free and save it with a file name of my choice to a location of my
choice. I do not want to use the default name "Form1.xml".

Also, I have a readonly text field called "lessonStatus" with a default
value of "not completed".

Before I save the .xml file, I would like to change the status to "completed".

The second thing that I would like to do is to save the .xml file with a
file status of read only. The idea is that the end user can reopen the file
and view it but can not make any further changes.

Please advise.

Thank you.
