[RESOLVED] Date Differences

[GrimmReaper]

OK, firstly, I know about DateDiff and TimeSpan...

I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.

I save the date in the registry like this:

 Application.UserAppDataRegistry.SetValue("Date", [Date])

I then made a sub to calculate the differences:

 Private Sub Calculate()
        Try
            Dim DateGen As Date

            DateGen = CType([Date], Date)

            Select Case TimePeriod

                Case "Every Minute" 
                    If DateDiff(DateInterval.Minute, DateGen, Now) >= 1 Then
                        RandomAlpha()
                    End If
                Case "Every x Minute(s)" '
                    If DateDiff(DateInterval.Minute, Now, DateGen) >= Duration Then
                        RandomAlpha()
                    End If
                Case "Every Hour"
                    If DateDiff(DateInterval.Hour, DateGen, Now) >= 1 Then
                        RandomAlpha()
                    End If
                Case "Every x Hour(s)"
                    If DateDiff(DateInterval.Hour, DateGen, Now) >= Duration Then
                        RandomAlpha()
                    End If
                Case "Every Day"
                    If DateDiff(DateInterval.Day, DateGen, Now) >= 1 Then
                        RandomAlpha()
                    End If
                Case "Every x Day(s)"
                    If DateDiff(DateInterval.Day, DateGen, Now) >= Duration Then
                        RandomAlpha()
                    End If
                Case "Every Week"
                    If DateDiff(DateInterval.Day, DateGen, Now) >= 7 Then
                        RandomAlpha()
                    End If
                Case "Every x Week(s)"
                    If DateDiff(DateInterval.Day, DateGen, Now) >= (Duration * 7) Then
                        RandomAlpha()
                    End If
                Case "Every Month"
                    If DateDiff(DateInterval.Month, DateGen, Now) >= 1 Then
                        RandomAlpha()
                    End If
                Case "Every x Month(s)"
                    If DateDiff(DateInterval.Month, DateGen, Now) >= Duration Then
                        RandomAlpha()
                    End If
                Case "Every Year"
                    If DateDiff(DateInterval.Year, DateGen, Now) >= 1 Then
                        RandomAlpha()
                    End If
                Case "Every x Year(s)"
                    If DateDiff(DateInterval.Year, DateGen, Now) >= Duration Then
                        RandomAlpha()
                    End If
            End Select

        Catch eg As Exception
            MessageBox.Show(eg.Message())
            tmrCalcGen.Enabled = False

        End Try
    End Sub

As you can see, based on the difference between these dates ( today's date and the registry date ), a sub gets called and the program continues.

Unfortunately, the minutes and hours never calls the RandomAlpha sub, because, I think it gets the wrong answer.

How can I calculate the difference in minutes, hours etc.????
