VB.NET How can I get first Date after 7 or 30 days?

[Hilal2009]

I made a simple complain management system in VB.NET, but I want to display daily, weekly, monthly and annual reports at any time when it will be required. The only hardness I'm suffering here is to get let's say the specific date just after the past 24hrs, past 7 days or 30 days

So can any one help me guys?
Even to get a sample of piece of codes to do that?

Thanks

Did you have a look at the DateTime structure ?

[Hilal2009]

Yes My friend and here below is my sample codes but I don't know how to proceed from here

Private Sub getDifference()
        Dim firstDate As Date = CDate(DateTimePicker1.Text)
        Dim secondDate As Date = CDate(DateTimePicker2.Text)
        Dim mydif As Integer
        mydif = DateDiff(DateInterval.Hour, firstDate, secondDate)
        lbDisplay.Text = mydif
    End Sub

I should rewrite lines 2 and 3 of your code as : Dim firstDate As Date = DateTimePicker1.Value
A DateTime substraction operator will give you back a TimeSpan structure. Use this further in some if else if decision code.
