<span style="font-family:Verdana; font-size:9pt Hi,
<span style="font-family:Verdana; font-size:9pt I am trying to write a "Simple" windows form application with C# that will take an input (A date) from an XML file, then compare the date from the XML file with the current system date and then give an
output in the form of a lable with the number of days in between the input date and the current date.

The issues I am hitting are to do with resetting the date within the XML file to today’s date (So the counter starts over) and getting the form to refresh every night so that it shows the true number of days since the date in the XML file (i.e so the form
counts up 1 at midnight every night).
Just a note: I’m a complete novice when it comes to C#, I first saw it about a week ago when I was asked to write this -_-.
Thanks in advance!

Here’s what I have so far:
