Web Forms :: Class Method Error "Arithmetic Operation Resulted In An Overflow"
Sep 28, 2010
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:
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 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:
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
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.
Dim roommates = From p In dbroom.Residents _ Where p.room = queryStudent.First.r.id _ Where p.building = queryStudent.First.b.id _ Where p.year = year _ Where p.semester = term _ Select p.person_name
It currently returns no results. I was getting an error when attempting to bind this resultset (since it was empty) to a repeater in ASP.NET, so I attempted to escape it:
If roommates.Count() = 0 Then Dim nomates As String = "No current roommates." rptrRoommates.DataSource = nomates rptrRoommates.DataBind() Else rptrRoommates.DataSource = roommates rptrRoommates.DataBind() End If
But I still get the same error:
The method 'First' can only be used as a final query operation. Consider using the method 'FirstOrDefault' in this instance instead.
This is very frustraiting because I have read a thousand posts on this and nothing works. I have a gridview which is programatically bound to a dataset which is created from dataset.readxml(xdocument.createreader). The table gets created without issue.
I have allow sorting set to true. when i click the sorting linkbutton I get the event handler error. So i create an empty event handler and that doesn't give me an error but also accomplishes nothing. So I searched and searched and found that i need to call the gridview.sort method to programmatically sort in the event handler. So when i do this
i get stackoverflow error. it creates an infinate loop. none of the 20 or so posts out there seem to answer how to handle this. They say that this method is the way to call sorting.
below is my event handler
[Code]....
the behaviour is that the event handler fires and executes to the sorting line which in turn refires the event handler.
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 write script to add meta information to mp4 video, when my script try to add mp4 meta information to mp4 file. I/O Error arises and operation terminated possibly cause of "no permission to open file". which permission is required to solve this issue. I am using ASP.NET. windows 7.
I created a method in my class which will determine if an input is a numeric value or not.
Code:
[URL]
And even I input a numeric value in my entry, still I get the error message "Invalid entry". Can anyone from this community have an idea on how am I going to solve this issue.
I have an ObjectDataSource that I want to perform updates using a business entity i.e. Type="Object"). Since the values for the entity are within a user control, I have stored a reference to the control in Session and in the updating event, set the new instance to the value of the entity from the user contol property (which also pulls values from the form viaother properties of the control):
Protected Sub MasterDataSource_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ObjectDataSourceMethodEventArgs) Handles MasterDataSource.Updating Dim entity As New Login() Dim accountControl As AccountInfo = TryCast(Session("AccountCtrl"), AccountInfo) entity = accountControl.Entity e.InputParameters.Add("entity", entity) End Sub
My question is, how can I get the update method to pass this entity to the update method in my BLL class? It seems the Update method requires an ID or reference to the original object to use in determining whether any changes have taken place, but I don't really want to do this. In other words, I just want to use the Update event on my ObjectDataSource to pass my entity to the method ("Update") I set as a property and then let this business method handle the update of the data. Shown below, is the BLL update method I want to call:
Public Overloads Function Update(ByVal entity As Login) If entity Is Nothing Then Throw New ArgumentNullException("entity") End If MyBase.Update("UpdateLogin", entity.Username, entity.Password, entity.FirstName, entity.LastName, entity.Role, entity.Region, _ entity.Email, entity.Title, entity.TierID, entity.Street, entity.City, entity.State, entity.Zip, entity.Mobile, entity.Phone, entity.Fax) End Function
When I try to call this as it stands now, I get an error: ObjectDataSource 'MasterDataSource' could not find a non-generic method 'Update' that has parameters: ID, entity. Previously, I'd set up a long list of parameters of basic data types (string, int, boolean), but this is rather cumbersome and I was hoping to use an entity for this (FYI, I also got the same type of error when I tried this approach, but with the ID as the last parameter in the list). Perhaps what I'm doing here is atypical to how the ODS is normally used?? Has anyone done something like this successfully?
I get an error for the below code in <script>. Until this line the images is loading fine: img.src = "images/4.jpg"But if I declare that line, I have an error message box that appears on the webpage: "Stack overflow at line: 0"I have never had this error before and wonder what is causing this as I need to declare alot of images in this way. As seen I am downloading one image at a time from the server ant putting it to its controls wich works fine until this line of code.
