i need that answer should not be zero but due to totalyear a integer variable inside if statement gives zero i want it to add a value 1 if num of months is greater than 5 kindly help me.

Hi I am getting the following error when computing GMT Time using nanoseconds as a long.

Is there another data type that would work better with big values?

It wouldn't let me add the code as the post is mostly code. The nanoseconds values are coming from a waveform file and this function is used to process it into GMT time.
The function is called on a loop for each line of the file and returns this error mid-way through the loop.
The value is '1.5518651852110167E+270' when it hits the error
I'm sorry but there's no way to put a 10^270 number inside ANY variable.
The biggest variable for numbers is Long that holds:
signed 64-bit (8-byte) integers ranging in value from
-9,223,372,036,854,775,808 through 9,223,372,036,854,775,807
(9.2...E+18).
From Long DataType
I sueggest you to avoiding counting time in nanoseconds instead use seconds, minutes, or even days if your TimeSpan is too big.
Counting time in nanoseconds is pointless.
Remarks
If you couldn't avoid using nanoseconds because your file is in nanoseconds your only option is to convert you nanoseconds value in a DateTime format on every line and hope that the value will be shorter than 9.2E+18
Otherwise you could use a BigInteger and use it to calculate a DateTime for every line of your file.
Just for the curiosity: You would need a 896 bytes unsigned DataType to store a 1.5*10^270 inside it.
Working on populating a row in excel with dates between a start date and current date. The population is weekly and below is the function I have made. It works fine up until the point where it doesn't stop but continues to go infinitely until there is an overflow error hence my assumption is that CurrentDate is not working properly.
The 2 dates used are StartDate = 04/1/2016 and CurrentDate = 12/07/2017.
Any help or suggestions would be greatly appreciated.
Public Function PopulateStartOfWeekDates()
Dim wsCRC As Worksheet
Set wsCRC = Worksheets("CRC")
Dim StartDate As Date
Dim CurrentDate As Date
StartDate = FirstMondayOfYear()
CurrentDate = Date
Dim WeekOffset As Integer
Dim i As Integer
i = 12
WeekOffset = 0
Debug.Print StartDate
Debug.Print CurrentDate
Do While StartDate < CurrentDate
wsCRC.Cells(5, i) = StartDate + WeekOffset
wsCRC.Cells(5, i).EntireColumn.AutoFit
i = i + 1
WeekOffset = WeekOffset + 7
Loop
End Function
If you decide you need to maintain the value of StartDate (e.g. to use later in the code), you could replace your loop with:
i = 0
Do While StartDate + i * 7 < CurrentDate
wsCRC.Cells(5, i + 12) = StartDate + i * 7
wsCRC.Cells(5, i + 12).EntireColumn.AutoFit
i = i + 1
Loop
After looking at this myself I realized I wasn't increasing the startdate hence the loop was infinite. Thanks to #Nathan_Sav for pointing this out in the comments too.
I am having issues trying to make a calculator that accurately calculates deposits plus the amount of interest that is added monthly. I dont know how to incorporate a loop that can add monthly deposits to total deposits, then adds the total deposits plus total interest times the interest rate / 100 / 12 to the total deposits. Here is what I have so far. Sorry am super new to VB !
Dim intMonthlyDeposit As Interger
Dim intMonthsTotal As Integer
Dim intAnnualRate As Interget
Dim decTotalDeposits As Decimal
Dim decTotalInterest As Decimal
Dim decTotalTotal As Decimal
Try
intMonthlyDeposit = CInt(txtMonthlyDeposits.Text)
intMonthsTotal = CInt(txtMonths.Text)
decAnnualRate = CDec(txtAnnualRate.Text)
decTotalDeposits = 0
decTotalInterest = 0
decTotalTotal = 0
decTotalDeposits = decMonthlyDeposit * intMonthsTotal
decTotalInterest = decTotalDeposits * (decAnnualRate / 100)
decTotalTotal = decTotalDeposits + decTotalInterest
lblTotDeposit.Text = decTotalDeposits.ToString("C")
lblTot.Text = decTotalTotal.ToString("C")
lblTotInterest.Text = decTotalInterest.ToString("C")
Catch ex As Exception
MsgBox("Enter a Valid Number")
End Try
End Sub
This is how I implemented the loop for calculating total interest and total deposits correctly.
For index As Integer = 1 To intMonthsTotal Step 1
decTotalDeposits += decMonthlyDeposit
decTotalInterest += (decTotalDeposits + decTotalInterest) * ((decAnnualRate / 100) / 12)
If i have a string containing a date formatted like this:
1402-3
which means Year: 2014, Week: 02 and Day number 3 (monday is 1), how can i convert this to a normal date? (in this case the date above is today; 2014-01-08 - wednesday 8 jan 2014)
Edit: I came up with a function like this, can anyone tell if this is gonna fail or maybe have a better and better coded function/solution?
Private Function StrangeFormattedDateToRegularDate(ByVal StrangeDate As String) As Date
Dim Y As String = "20" & StrangeDate.Substring(0, 2) 'I'll be dead before this fails, haters gonna hate
Dim W As String = StrangeDate.Substring(2, 2)
Dim D As String = StrangeDate.Substring(5, 1)
'Get first day of this year
Dim RefDate As Date = New Date(CInt(Y), 1, 1)
'Get the first day of this week (can be the year before)
Dim daysOffSet As Integer = DayOfWeek.Monday - RefDate.DayOfWeek
RefDate = RefDate.AddDays(daysOffSet)
'Add as many days as the weeks is
RefDate = RefDate.AddDays(7 * CInt(W))
'now the date is the last day of this week (plus one day), remove the days that are ahead, and remove that extra day
Dim daysToRemove = ((7 - CInt(D)) * -1) - 1
RefDate = RefDate.AddDays(daysToRemove)
Return RefDate
End Function
This should be what you're looking for :) This looked challenging so I tried it. Tell me if it works for you or not :)
Function GetDate(InputDate As String) As DateTime
Dim FirstDayofYear As Date = CType("1/1/20" & Mid(InputDate, 1, 2), Date)
Dim LastDayofYear As Date = CType("12/31/20" & Mid(InputDate, 1, 2), Date)
Dim target As Date
For x = 0 To DateDiff(DateInterval.Day, FirstDayofYear, LastDayofYear)
Dim dfi = DateTimeFormatInfo.CurrentInfo
Dim calendar = dfi.Calendar
Dim weekOfyear = calendar.GetWeekOfYear(FirstDayofYear.AddDays(x), dfi.CalendarWeekRule, DayOfWeek.Sunday)
If CInt(Mid(InputDate, 3, 2)) = weekOfyear And CInt(Mid(InputDate, InStr(InputDate, "-") + 1)) = FirstDayofYear.AddDays(x).DayOfWeek Then
target = FirstDayofYear.AddDays(x)
GoTo skip
End If
Next x
skip:
Return target
End Function
This works up to Year 2099. We're probably all dead by then.
