This nice table is getting the error:
An unhandled exception of type 'System.StackOverflowException' occurred in System.Data.dll
Dim reader As SqlDataReader
Dim cn As New SqlConnection(connectionstringvariable)
[code]......
What I want to know is that in VB.net is it possible to get a stack overflow, and if so how is it caused. What I mean is, what sort of written code would cause a stack to overflow.

I'm writing this program in Visual Basic .NET to organize different fields of data, and I'm using profile slots through application settings to store the data for users. But, I ran into a stack overflow error in my SlotSelect.vb class. My best plausible guess for why this happens is that I'm using the wrong kind of variable container in the below sauce code, but my dilemma is that I don't know what specifically is going wrong.The code that the vshost is saying is the cause for the overflow was written from some code that I looked up on MSDN and other places for referring to objects in other classes, and I tried using other variants of it to see if it was any different. So far, nothing has worked, and it doesn't stop the error while compiling, much less in the code markup--it only catches it when it starts the application in debug after it finishes building
View 7 Repliescould 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 created quite a few web chats using VB.NET and ASP.NET and I'm just wondering how Stack Overflow handles messages being sent back to clients. Because web can only make requests and get responses back once, how does Stack Overflow handle messages? In my implementation I have a recursive loop that gets called every 1 second and makes an Ajax request to the server to get the latest messages, but I am thinking of using web services
View 2 RepliesThis is probably a stupid question but is there anyway to prevent a stack overflow error from occurring in your VB.Net app?
View 3 RepliesI 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

Now I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..

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)

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.
I get an 'overflow exception was unhandled' error in the following code.

I need to make some big multiplications for cryptographic reasons in vb.net and overflow the variable as C,C++ and C# does. I have disabled the check of overflow at the vb.net project but when i an doing those multiplications i get as a result 1.#INF
ex. in c:
z^y= 0xFFFFFFFF ^ 0x000003FC= 0xFFFFFC03
in vb.net:
z^y= 0xFFFFFFFF ^ 0x000003FC= 1.#INF

I can't prevent the table from expanding beyond the normal row height to stack text in a cell. It wraps text if strings are too long. I have tried everything and nothing is working. I have tried using overflow:hidden + height; i have tried text overflow ellipsis?
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 finished a project ive been working on for weeks or well i thought i had finished it.. in VS debug environment it runs fine doing its logics for hours without a problem but after publishing it as a standalone it starts throwing errors pretty soon. Took another look at whats going on in VS debug and the only thing that stands out is "A first chance exception of type 'System.OverflowException' occured.." that pops up every now and then so i think this is whats crashing my program outside vs. This poses 2 problems a) the code is around 2k lines/3 classes and heavily multithreaded and i have no clue where exactly this error gets generated, b) from my previous encounters with first chance exceptions they seem like more "possibility for error" instead of an actual error itself and very hard to track down
View 1 RepliesI've started using .Net's stack collection. The basic features I guess are the "pop" and "push", where you add or take off the top element of the stack (if you are referencing other elements in the stack then another collection type is probably better).[URL]..it appears that the Stack collection (like other collections) is basically an array with some window dressing (so you actually can see other elements). As far as I can tell, "popping" and "pushing" is changing the first element of the array. Shouldn't instead the final element be the "top" of the stack and be the one that is changed? Otherwise the program has to reindex all the other elements in the array every time a pop or push is made. This seems very inefficient. But this is what Microsoft's description appears to be saying what is happening.

View 3 RepliesI just started programming in VB.NET 2008 with the Express edition and have been having a blast so far. I thought a fun program to try and make would be an infix to postfix program.
I have five text boxes off to the side of my program that shows what is on the stack as you iterate through the equation. I'm wondering if it's possible to make these textboxes set to display what is at a certain index of a stack.
For example, if I pushed a "(" onto the stack, I would like the top box of my textboxes to update and show a "(". When something else is pushed onto the stack, say a "/", I would like the "(" to be displayed in the second box down, and the "/" to be displayed in the top box now.
I did alot of work then I suddenly get this error message
View 2 RepliesWe have this funky little ObjectDisposedException happening now and again. But only on production machines, of course ... can't recreate the issue on my dev unit. So I trotted on out to the Microsoft site to see what members of this exception I could use to figure out what's going on. Microsoft says that one of the members is StackTrace. I double and triple checked that I'm looking at .Net 1.1 information as I'm pretty sure that's what I'm using (how can I check that?). Here's the page I found - [URL]
So I go back to my program to write something useful to the event log so I can figure out what's going on. And when I look at the members of the ObjectDisposedException available to me I only see the following: GetBaseException, GetType, InnerException, Message, ObjectName, ToString.
what happened to my StackTrace member? I sure could use it if I could figure out how to get to it.
As a learning experience I decided to try and implement the Shunting Yard Algorithm(string calculator) using OOP. It was successful for as far as I took it, but it had one flaw. In order to get the stack to be accessible from the operators I had to declare it as shared, which meant that all versions of the calculator shared one stack. This very short piece of code illustrates what I came up with and the "flaw". [code] How can I maintain the functionality of anOP.add1 without declaring "something" as shared?
