DateTime Arethmetic Overflow Error
Nov 15, 2009
I am creating a list of dates between two dates and inserting that list into a DB like this:
Dim SDate, EDate, iDate As
Date
Dim DateString
[Code].....
When I use some StartDates and End Dates like 04/11/2009 and 06/11/2009 it works fine and I am able to get the info into my DB. However; when I use other dates like 04/11/2009 and 13/11/2009, I get the following error:
Arithmetic overflow error converting expression to data type datetime. The statement has been terminated.

I've never seen this error before; and apparently (According to DIC) the number would have be bigger than -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, to this this exception (I'm using an Integer, but I've tried Int64, and the same thing happens).
This is where the exception is being thrown:
Dim localPort As Integer = (tcpRow__1.localPort1 << 8) + (tcpRow__1.localPort2) + (tcpRow__1.localPort3 << 24) + (tcpRow__1.localPort4 << 16)
Full Code (Method)
[CODE]...
I highly doubt that that the integer that is being parsed back is greater than, either of those numbers listed above. I've tried using Int64, and even removing the << operator, but it's still throwing this exception.

We have a VB application, which will get input from the user, post it to HTTP url and get the result from it, assigns it to objects and displays it to user.
In this flow, users are getting Run-Time error 6(Overflow). But this is not happening all the time. Iam not able to reproduce also?Would there be any other reason for this, apart from normal reasons like assinging a higher value to lower datatypes.

I'm trying to make a grade calculator that can determine the minimum grade you need to acheive a desired grade. I'm new to visual basic, and I'm trying to figure out why I keep getting the run-time error '6' message. I tried declaring the variables as variants instead of doubles to fix the problem, but it didn't seem to work. When I click "debug" the red statement is highlighted.!

could you tell me, why I get the stack overflow error on this code?
Dim ev As Double = datum.Year * 365 * 24 * 60 * 60
Dim honap As Double = datum.Month * 30 * 24 * 60 * 60
Dim nap As Double = datum.Day * 24 * 60 * 60
Dim masodpercek As Double = ev + honap + nap
The double datatype should be enough.

I have a major problem. Things were going great until I came across this little bug(?) which has thrown a stick in my spokes. As I will demonstrate below, it seems that when defining certain numbers Visual Studio will throw an overflow error.
Dim T As ULong = 14774537964905701134 'Overflow error in the IDE
Dim M As ULong = ULong.MaxValue '(18446744073709551615) we are below the maximum value so it should work, right?
The one solution I have found is that we can use the following declaration instead.
Dim T As ULong = ULong.Parse("14774537964905701134")
However, to make matters even more complicated the value in question is unknown and must be compiled using CodeDOM so using the Parse method isn't an option. Unless there is some way I can determine if that value in particular will give me an overflow error.

I have a program that sends out mass emails. My problem is that at the end of the program....I keep getting a "Stack Overflow" error and I cannot figure out where this might be happening. This program is a VB.Net 2005 console application which is ran manually from the command line. The code below that I have posted is what sends the actual email. I don't think it has anything to do with this error but my question is this. Do I need the highlighted line of code? I'm thinking I don't since the mail object is already being disposed...but I'm not positive.
Dim oEmail As New System.Net.Mail.MailMessage()
oEmail.From = New MailAddress(strSender)
oEmail.To.Add(strRecipient)
oEmail.Subject = strSubject

If dgCell = "Delete" Then

Error is thrown at "cmdDelete.ExecuteNonQuery()". Sql query still deletes the record. I have run query against the database itself and I get no error. I am using an as400 db and vb.net 2008. I'm not sure if this is problem with the database or vb. I get this error when I run the delete above, also when I run an insert or an update.

I am new to VB. I was trying to insert a record into access database with data reader. I was getting OVERFLOW error at runtime. My understanding is that overflow error occurs when we assign values that to variables that exceeds the maximum size of the data type.
Following is my code
Private Sub InsertRecord(ByVal CustomerID As Integer)
Dim RowArray() As String = Split(Me.lblRow.Text)
Dim intPrice As Integer
Dim decTotalPrice As Decimal
Dim mySQL As String

We have data feed, a file with index values and dates (like the S&P 500, for instance). The dates are represented as YYYYMMDD. The Date.Parse() method doesn't understand this format, of course.I wrote a simple static method on a class to parse this, not a big deal, but it irritates the engineer in me that I can't figure out how to get the IFormatProvider functionality to work. All the examples deal with the FORMATTING step, not the PARSING step.So basically, I want to be able to say:
Dim d as DateTime = Date.Parse("20110522", New CustomFormatter())
and get the correct date value out of the Parse method.
Having implemented the IFormatProvider method on CustomFormatter, the GetFormat() method gets called with a System.Type of DateTimeFormatInfo, but I honestly have no idea what to do from there since all the example deal with formatting, not parsing. It doesn't matter if I return an object (self) or null I simply get "String was not recognized as a valid DateTime."

I'm having the following error message with a date value in production server. "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value" In the development server the problem never happened. Both production and development servers have the same OS (Windows Server 2003), updates and settings including the regional settings options. The regional options is set to Arabic (Saudi Arabia) and the date is customized to use (English) gorgerin calendar. The non-Unicode is set to Arabic (Saudi Arabia).
My solution contains an ASP.NET web application and a class library. In my class library project I'm trying to get a list of rows from the database (SQL 2005) and I'm using a date rang [Code] Is there a way that I can use to manipulate dates regardless of the regional options settings?

Error converting data type varchar to datetime.rtfI am trying to learn ASP.NET using ASP.NET 1.1 with SQL Server 2000 for the database.

The problem is that when I try to save a record, the date field returns the above error. I have ried to use the several solutions on the web without getting one to solve the problem.I am attaching the Stored Procedure as well as the ASP.NET code for some advice. I am also attached a word document containing the two procedures.

I don't understand where else it could be screwing up. I'd love to be able to keep it to a null value if it is one already, I'm just trying to get it to take anything right now and this is where I'm at.

Im having an issue with a Stored Procedure I have written,I can call it in management studio and it works fine, yet calling it from my codebehind gives this error The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. when i call da.Fill(dt)What is really puzzling me here is that I dont actually convert anything from varchar to datetime, the most I do with the date variables is format them into a different datetime format.
My VB.Net code
Private Function dbGetEvents(ByVal start As DateTime, ByVal days As Integer) As DataTable
Dim dt As New DataTable()[code].....
I cant see where this error could be coming from, having tested running it in SQL management studio without error I am pretty sure the error is in the VB.My first thought was that maybe the parameter I am passing in the @start / @end values arent being recognised as DateTime so I tried adding the parameters like:
Dim p As New SqlParameter
p.SqlDbType = SqlDbType.DateTime
p.ParameterName = "@start"[code]....
