VS 2010 Downloader Program - Arithmetic Operation Resulted In An Overflow?
Feb 24, 2011
I'm making a downloader program in Visual Basic 2010, and it calculates the current download speed, the approximate time left and all that good stuff.But when I download certain files, the program decides to f*** up.The program stays still for a bit, and nothing happens when i click download button, but then all out the sudden the download starts like normal but an error message pops up and it says:
"Arithmetic operation resulted in an overflow"As I previously said, this error message only pops up on certain files.Then I started to do some "error-investigating" xD, and i found out that this line caused the error msg:
dlspeed = e.BytesReceived / SW.ElapsedMilliseconds
remainingtime = ((e.TotalBytesToReceive - e.BytesReceived) / dlspeed) / 1000
lbl_dlspeed.Text = Math.Round(dlspeed) & " kB/s"
That code is written in the web_downloadprogresschanged class.And SW is a stopwatch.I mean, it still downloads fully and such, but it looks ugly when an error message pops up even though it works.

Ok so in my code i need a ****ing long as equation to draw a certain paint for getting the distance of a particle using the terminal velocity equation. which looks like this...
var.vt = ((2 * var.m * var.g) / ((var.fluiddensityp) * var.apaos * var.dragcoef)) ^ (1 / 2)
then pop that in here to get terminal velocity at a given time...
= var.xvalgraph1 * ((var.g * var.fluiddensityp * var.dragcoef * apaos) / (2 * var.m)) ^ (1 / 2)
terminalvelocityovertime = vt * Tanh(tanhx)
then as I'm drawing a graph i calculate the previous coordinate and join then with a line.so i need a value called previous which is where ever there is a var.xvalgraph1 it minuses what ever time increments have been set so alll var.xvalgraph1 turn to (var.xvalgraph1 - var.timeperpixel)
ok thats all fine this is where the equations get too much and i don't work

Why a variable defined as a long will not accept this number (2,148,532,224) with out throwing an exception of "Arithmetic operation resulted in an overflow." Looking at documentation it should be able to handle a value up to 9,223,372,036,854,775,807.
My code does some simple calculations and then tries to store the value in the variable.
Dim mdblTotalFileSize as Long = GetImageSizeBlocks * GetBlockSize
The value for GetImageSizeBlocks is 1049088 and the value of GetBlockSize is 2048 which equals 2148532224

In this call to method SetVolume, Volume = 2055786000 and size = 93552000. Volume is an Integer property, and size is also Integer, as you can see.The class is a partial class of a dbml entity class, however this Volume property is NOT a column in the database, it exist only in the partial class, as a "business object property".

I am using the following code to add some value to a date:
Dim strdate As Date
Dim numinterval As Double
numinterval = 149548.720386359
strdate = DateAdd(DateInterval.day, numinterval, #1/1/1601#)
MsgBox(strdate)
The value numinterval is the number of days passed since 1/1/1601 (this is how date is counted for things like 'last logon time', 'last bad password' in Active directory). I do some calculation and get that numinterval value in days.. But since I want it to return the time more accurately, I tried first multiplying numinterval by 1400 for number of minutes.. And I changed the interval as dateinterval.minute... That worked fine!
But, when I tried again by multiplying it further by 60, to get the time accurately in seconds and changed the interval to dateinterval.second it throws the following exception:
Arithmetic operation resulted in an overflow
I changed the type of numinterval into long, but the same problem..

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 attempt to prepare printing document by using WinAPI instead of (System.Drawing.Printing.PrintDocument) because Graphic.DrawString does not render Khmer Unicode properly. Only TextRendering.DrawText renders it properly. I believe Graphic is GDI+ wrapper and TextRendering.DrawText is using GDI. Furthermore, PrintDocument does not work with TextRendering.DrawText.

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.

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 written my own program to assist other engineers with their work at my company. Some people have been able to install the program with no problems, others can't seem to get it installed and I'm having trouble figuring out why. They install .Net Framework 4 as this is the Target framework that was setup in the file, although I don't think I fully utilize all the features yet and not sure when I will. I will post the portion of the log that contains the error. If anyone decode some of this so I can track down the problem. I'm not sure if downgrading the necessary version of .Net would work or not, but didn't want to be changing that unless there was a good reason too.

I must convert string data from a CNC that is arithmetic expression to a number that I can use in a VB application that I wrote. The following is what I get out of the cnc. [18722*65536+19377]/67108864. I need to evaluate this expression in my VB ap. The format of the string is not always the same as what I have illustrated.

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

I have an application that deals with some rather large number values. I wanted the values to allow a roll over so I compiled the program with Remove Integer Overflow Checks turned on. The 32 bit numbers roll over just fine but the 64 bit unsigned integers still throw an over flow exception. Is this a bug in the compiler?

I have written a program that searches a bunch of urls and pulls out information that I need. The program works to an extent. Everything codewise works, but it seems like I did a sloppy job of pulling the code together. After about 10 minutes of running, the program just becomes unresponsive and I have to close it through task manager. I've seen it range from 100k to 350k in memory useage. It also uses about 80%+ cpu usage at all times. I hope someone might be able to see something that I forgot or did wrong as the program is meant to run almost full time, executing parts of code on certain days/times.
