Value Was Either Too Large Or Too Small For An Int16 Error
Jun 9, 2010
I am working on fixing a bug in VB that is giving this error. I am new to VB, so there is some syntax that I am not fully understanding. The code that is throwing the error says:
.Row(itemIndex).Item("parentIndex") = CLng(oID) + 1000000
I understand that adding 1000000 is too much for an int16. I can't change that value (not right now anyway). What I don't understand, and can't seem to find, is what .Row is referring too.

When I try and run the program I get an error stating
"Value was either too large or too small for a Decimal."
On the line that says
principal = payment - InterestPaid
I've included the rest of the code as well. Perhaps this is a downside of staring at the screen for so long.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim payment As Double
Dim result As String

I have writen a program in Visual Studio 2005 professional. Part of the program functions is to store customers details. Part of this details include a phone number. I can add a customer and include his/her telephone no. which is 12 digits long. But when retreiving this customer I get the following error.Value was either too large or too small for an Int32. Couldn't store <+23320805060> in Phone Column.Expected type is Int32.The program runs fine If the phone numer is less than or = 9 digits. The datatype i am using is for the phone column is varchar(50). I have tried to change the data type to bigint, int and nvarchar(50) but the problem seems to persist. I am using the SQL database but i seem to be hitting a brick wall on this matter.

I have a large wikipedia dump that I want to cut into different files (1 file for each article). I wrote a VB App to do it for me, but it was quite slow and crapped out after a few hours of cutting. Im currently splitting the file into smaller 50mb chunks using another app but thats taking a long time (20-30 minutes for each chunk). I should be able to cut each of these up individually if I do this.
Does anyone have any suggestions of a way to cut this file up quicker?

So, I have a little issue.. I can't currently explain it using the software I'm developing because it's "internal"... So I'm going to describe it as an email serverAnd the email server has a fair number of email accounts, and I want to save the accounts emailFor development, I've been saving it all in a list of a structure (this sounds worse than it is, the data actually is no more than 120 bytes per "email")

I have spent way too much time trying to sort this little issue out. I have narrowed down the issue to the exact procedure that throws the error. Yes, I have used Google..
Try
Dim tempSource as String = Nothing
Console.WriteLine("Loading document...")

I am loading a text file, that contains about 1100 lines, and each line is going to be processed with HTML Agility Pack. From what I can tell, when it runs "doc.loadhtml(richtextbox1)", it throws the error. I also have tried to load the file into a string, and load the string with "doc.loadhtml(thestring)". It doesn't make a difference, still errors.
Here are is a sample of how each line looks:
<Site Index="" Name="" Group="" PR="" />
<Site Index="" Name="" Group="" PR="" />
[code]....
I am using HTML Agility Pack, however the above is what is on every line, about 1100 lines! For testing, I have a smaller text file made of about 50 lines before I load up the 1100 line file ;) There aren't any HTML, HEAD, or BODY tags! They aren't needed for my parsing. I am using HTML Agility Pack because it is easy to parse elements with. I can grab each value easily from each line.
I am not sure if maybe the error is because it technically isn't HTML? Meaning since the loaded code doesn't have an HTML or BODY tag, that it errors? I wanted to get this question posted, and while I am waiting on some answers, I am going to parse the document another way. Just curious as to what the deal is and why HTML Agility Pack isn't working. More of a proof of concept then anything, for my own learning and knowledge.
Here is the error I get (btw the on the doc.load() line, is where it throws the exception):
Object reference not set to an instance of an object
Last Note: The routine is on a background thread. I have used multi-threading before, and have delegates created for deeper in the code.

(using vb.net) On our intranet site we have an app that loads customer or vendor information and then allows the users to edit info and add/update/delete contacts. I'm not sure what really changed to this program lately, but I keep getting this error:
Method not found: 'Int16 DBLayer.DBTools.ExecuteNonQuery(System.String, DB)'.
This occurs when i try editing any customer info and the vendor contacts, but the program works when I try editing the vendor info/addy. Here's the program code. There's a seperate program on our webserver that contains the classes used. Here's the main code that calls the classes:
TO ADD CONTACT
M2MInterface.M2M.Customers.AddContact(Session("CustVendID"), txtFName.Text.ToUpper.Trim, txtLName.Text.ToUpper.Trim, Tools.RemovePhoneNumberFormat(Phone), Tools.RemovePhoneNumberFormat(Fax), txtEMail.Text, txtNotes.Text, False)
TO UPDATE CONTACT

I want to write a program to do Markov chain, but my states are quite large. First of all I calculate all the transition probabilities and revenues for all states(1381860 total states), and store in a multidimensional array. Public RevArr(0 To 9, 0 To 750, 0 To 282) As Long
After that the iteration of markov chain should use these as inputs to calculate the steady-state probabilities. But when I try to run the main code I got this error.Exception of type 'System.OutOfMemoryException' was thrown.
The following is the declaration of second array I add just another dimension for storing all the iterations, but I get this error. Dim stateprob(IT + 1, 0 To 9, 0 To 750, 0 To 282) As single

I have a vb.net Windows application that calls a vb.net Web Service function. Both the vb.net application and Web Service have been in use for over 5 years and have worked well. The Windows App builds a text file consisting of a number of inserts into an Oracle table, followed by a call to an Oracle package. The Web Service call uploads the text file to the Web Server, loops through the statements in the text files and executes them. It then does a Select statement to put the resultant data in a string which is passed back to the calling program. We have both people on our local area network as well as external users where the call to the Web Server is over the internet.
The data string returned is the pricing for each of the lines inserted in the text file, separated by asterisks. Normal use of this call has anywhere from 1 to a few dozen lines, and the program works fine for this for both internal and external users.
Our problem right now is one external person is attempting to price a job with 491 individual line items. At first it would not price, whether the job was priced from a computer at the customers site or one of our internal people on the LAN. The problem turned out to be the timeout value was not long enough (it was set at 2 minutes, this job takes 5 minutes) so changing both the Timeout value in the Web Service call as well the httpRuntime executionTimeout value in the web.config file on the web server addressed the problem, but only for our internal users on the LAN. Our external customer wants to be able to price jobs of this size going forward, and I am at a loss as to why it errors on internet connected machines but not locally connected machines. Our customer is in New York, We are in Wisconsin, and I am able to recreate the error condition from my home computer.
The other thing is, if I create a VPN connection to our server from my computer at home, this job will price (again, it takes about 5 minutes) but if I disconnect the VPN connection, it gets an error after approximately 3 minutes, http 404: Not Found.The customer can otherwise price all of his other jobs with no problems, it's only this one, very large job that gets the error.

I have developed software which can upload and download a large amount of data.
I am using language = .net 2005 ,OS = XP (32bit) , processor = duo core (3.00 GHz), RAM = 2GB. I have read a file up to 50 mb and then split it 2mb each. So no of pieces of the total 50 mb file will be 25. This split 2mb file will upload 25 times. But in this case I always get the exception "The operation has timed out" . I don't know why this is happened. Is it the fault of Internet connection speed or else ? Except this upload when I download the 2mb each, up to 50mb then I got 'System.OutOfMemoryException' .
Actually I have download 2mb file at a time and concat it in a stringbuilder object. This will do up to 25 times. But suddenly when it concat the string it get the exception 'System.OutOfMemoryException'.
I don't know why this happened. If I used up to 14mb file. It properly uploads and downloads but if I used the large file like 50mb then it get error. I have given you a sample code, so that you can understand the problem.
Private s_ReceiveMessage As New StringBuilder()
Dim data as string = ""
data = "2mb DATA"

I'm having trouble getting started with this application I need to do. Here are the details:
Its an application to calculate student grades for a group project. Create a text file to store names of 5 students, line by line. In a separate file enter peer evaluations from 0 to 1.0. Enter these numbers for evaluations:
1.0, 0.8, 0.9, 1.0, 0.6
0.2, 0.9, 0.5, 0.6, 0.7
0.5, 1.0, 1.0, 1.5, 0.9
0.9, 0.9, 0.9, 1.0, 1.0
1.0, 0.9, 1.0, 0.8, 0.9
This means that student 1 gave 1.0 evaluation for himself , 0.8 for student 2, 0.9 for student 3 etc.Student 2 gave 0.2 for student 1, 0.9 for him- herself, 0.5 for student 3 etc. Read these into a 2-dimensional array. If any of the values is greater than 1.0, set them to 1.0. The program should calculate the average evaluation for a student. While doing so, the program should ignore evaluations that student gave to him-herself. Populate a list box with student names when the form loads. The user should enter a project grade (same for everyone) in a textbox. Then the user can select a student from a list and click �Calculate� button. The program should display the project grade for that student by multiplying average evaluation by the grade for the whole group (project grade).
