C# - "Arithmetic Operation Resulted In An Overflow." ContentLength Is Always -2?
Mar 31, 2011
I have an update panel that works lovely in my test solution but when I put it into the main project it does not work correctly.I've made it very simple, but still no joy, it consists of:the file upload controla link buttonthe link button has an onclick method that takes the file and creates a byte array. For some reason the contentLength is -2 every time. It does not matter what type of file I am using. Every time!
This is very frustrating considering it works fine in my test solution.Is there anything I am missing or should be looking at? EDIT:I am using VS2008CODE:
I do not understand how this problem happens, and I need help. The code below is very simple. It collects data entered into controls; instantiates a class; then sends the data to a class method for processing. No resulting value is returned to this code.You can see that there are no areithmetic operations performed on the data, but I sometimes get the error "arithmetic operation resulted in an overflow" right here on the last line cRating.SetRating(etc...).
[Code]....
The class method uses the player id values (single) for the two players (iHPlayerID and iAPlayerID) to find their rating values. Calculations are made and the database is updated.Observation 1:I don't want to discuss the class method too much because, and this is the odd part,the code behind breaks before reaching the class. I have inserted a breakpoint at the start of the class method and ran the code. The error occurrs and the class codenever appears.
Observation 2:I mentioned that the class uses the players' ID values to look-up their rating from the database and round that value (single) to an integer. The code works just fine if the integer values of the players and not the same. The code fails and gives the error every time if the integer values are the same. How can this happen if the class code never executes?
I have a class that runs calculations on numbers and populates the results to my SQL database. My code behind page instantiates the class object, and in a loop it makes use of the method five times (once per loop). Essentially, my code behind collects the information from controls and passes the information to the class method for processing. The method works just fine most of the time.
On one of the iterations I get a error before the code even gets to the class. The error is, "Arithmetic operation resulted in an overflow." What strikes me as odd is that while stepping through the code, the loop crashes with that error before getting to the class that runs the calculations. Additionally, no arethmetic operations are performed on the form's code-behind page (which calls the method). I even put a break-point on the class constructor but the code crashed before reaching that constructor.
The information being sent is the results of matches from a sporting event. As a troubleshooting measure I changed the order of the matches by deleting them an re-entering them into the database in a different order. Again only this one particular match crashed. Here is the code that crashes:
using sql server 2005. I am working with an existing database field and there is a field where the string in this format: YYYYMMDD, for example 05/16/2002 is displayed as:
<example> 20020516 </example>
anyways I am trying to convert that string to a date like so:
[Code]....
however when I try to do this I am getting the following error <ERROR>
Arithmetic overflow error converting expression to data type datetime. </ERROR>
does anyone know a good solution for this? I just want to convert the string to datetime so I can use the value in my WHERE clause.
While executing select statement for a table then iam getting arithmetic overflow error.I found that retrieviing the data for a particular column showed that error ,sum() for that column is showing error.Is there any way i can rectify this problem.
I am trying to insert a value in database from a dropdownlistddlvaue = 10.00 - 11.00in db asstarttime=10:00:00endtime=11:00:00using split function
string dropdownvalue = ddlduration.SelectedItem.Text.ToString(); string et = dropdownvalue.Split('-')[1].ToString(); endtime = et.Split(' ')[1].ToString(); starttime = dropdownvalue.Split(' ')[0].ToString(); I am joining date value + time value in the query uisng('" + datevalue + "' + ' ' + '" + starttime + "')
'2014-05-15' + '16.00' --> to get 2014-05-15 16:00:00
it is getting inserted successfullybut while selecting and viewing it from the database I am getting error as,
"Arithmetic overflow error converting expression to data type datetime"
If i mannually enter the date in db it is workingmanuall value=2014-09-30 14:00query value =2014-09-30 14:00
both are same but error is only occuring for query inserted value
in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.
I'm currently learning entity framework (from the Julia Lerman book "Programming Entity Framework") and got really confused at the grouping part.
var contacts = from c in context.Contacts group c by c.Title into myGroup select myGroup;
This is supposed to return a Grouping<K,T> type, but the book didn't give an example on how exactly do I access this "contacts" query and I can't figure it out. When I did foreach(var contact in contacts), my "contact' variable has no knowledge of any of the properties of the Contact type (contact.FirstName etc).
I am developing a website in asp.net mvc using Entity Framework. I have created some POCO (Plan old class objects) to represent the database entities.These POCO classes defines some entities with datetime type.
Now I have a view which contains a telerik datepicker. This view inherits the model which contains a nullable datetime object say searchDate.
When I fire a query to compain these searchDate with dates stored in database its throwing following error
"SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."
following is the linq query i am using
[Code]....
The date format stored in database is "2011-01-31 00:00:00.000"
and the format comes from UI is "03-03-2011 00:00:00".
I am using SQL Server 2008 R2 and .net 4.0 framework.
I have set a fix height of DIV and set its overflow-y:scroll but the problem is that if i have got data less than its height event though its showing scroll bar (disabled). how can i hide it... i mean give me solution so that the scroll bar will only show when data in that DIV is crossing height of DIV..
My code :
<div style="overflow-y:scroll; height:290px"> a data grid is here </div>
we are getting a stack overflow in production ~ 2-4 times / dayWe cannot reproduce this is in dev environment, nad given this is a web app with probably ~100 concurrent users at any one time, I'm struggling to work out how best to track this down.Is there anyway to get any more info from event viewer - happy to install some form of listener tool - even if i can just get teh thread identity (set to the current user) that'll help - although the dll + class / function woudl be great!
On this site if you do too many clicks or post comments too fast or something like that you get redirected to the "are you a human" screen. Does anybody know how to do something similar?
I have made a solution with ResizableControlExtender in the Ajax control toolkit. It is a solution with a treeview on the left side of the screen and a content panel on the right side. Depending on what level in the treeview the user clicks at different content is shown in the right panel. What I want to do is to make it possible for the user to resize the width of the treeview. I have put the treeview in a panel and sets the target for the ResizableControlExtender to this panel. I have set the overflow style to auto. This works fine in all browsers except IE6. Unfortunately IE6 is an important browser for this solution. In IE6 the text of the treenodes is not cut when it is wider than the treeview width so it flows over the borders.The overflow works if I set a fixed width in the styleTreeView class but that makes it impossible to resize. I've tried to change the overflow setting in a lot of ways but nothing is working.
I have used a MaintainScrollPositionOnPostBack = true function in 2.0 but is giving a stack overflow at line 0 error. What is the fix to this. I understand that it is a bug in IE.
I have a MS SQL Srver 2005 Database, that has a table with a DatTime column. The DateTime column is of smalldatetime type. The date and time is auto generated by the DB using getdate() function. This is because its a LOG recording table, so logs are just inserted and date-time is generated by the db.
When creating a log and saving into the DB through Entity Framework, using LINQ query, it causes an error while saving saying:
"SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."
upon investigating using breakpoints i have noticed, when Entity Framework tries to save the Log object, the date set by Entity Framework is set to:
01/01/0001 00:00:00
I guess this is why error is coming up. Is there any way to resolve this?
I'm new to ASP.net 3.5 and I'm trying to create a FormView based on Linq to SQL. My underlying table has several date fields that are optional and typically are not set. When I try to insert or update records, I get the following message.
SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM
I got the same message when using the SQLDataSource with this data, but I was able to create functions that tested the value of the datefield against the datetime.minvalue and if it was the minvalue, replace it with null.I can't figure out where to put the functions and how to reference the value of the date field. below is what I have
-- CURRENT FUNCTION FOR LINQ TO SQL
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of SqlDateTime) If IsDate(pasDate) Then Try [code].....
How can I submit null dates when using Linq to SQL automatic updates and inserts?
