Calculating monthly bill date

Hello all,

I'm doing a simple db that stores customers using an internet service, billed monthly. How do I automatically calculate the monthly billing date. This will be the same date every month based on the date service began. The start date is stored in the database, but I am not sure how to auto calculate so that I can notify the user daily. Each customer will generally have a different payment date....

Thanks in advance!

example

Code:

---

string startD="2/15/2008";
            DateTime d1 = DateTime.Parse(startD);
            DateTime d2 = d1.AddMonths(1);
            MessageBox.Show(d2.ToShortDateString());

---

Ok thanks. But how would this work 2 months after the due date?

I converted what you gave me to vb.net...

Code:

---

       
Dim startdate As Date = BillDateDateTimePicker.Text
        Dim d1 As Date = DateTime.Parse(startdate)
        Dim d2 As Date = d1.AddMonths(1)

        MsgBox(d2.ToShortDateString())

---

I would actually have a couple more fields.... NextDueDate and LastPaymentDate.

When you process the next due always update the next due with the new value.

Your code should look like this :

Code:

---

       
Dim startdate As DateTime = DateTime.Parse(BillDateDateTimePicker.Text)
        Dim d2 As Date = startdate.AddMonths(1)

        MsgBox(d2.ToShortDateString())

---

So you pass '2' as parameter in AddMonths function.
