Arithmetic Operation Resulted In An Overflow?
Apr 6, 2011Ok 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

Arithmetic Operation Resulted In Overflow
Feb 8, 2010Why 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

View 6 RepliesDateAdd Function - Arithmetic Operation Resulted In Overflow
Jun 15, 2010I 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..

VS 2010 Downloader Program - Arithmetic Operation Resulted In An Overflow?
Feb 24, 2011I'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.

The problem is that, when I call the "SetStatusBarText" sub from another thread, InvokeRequired is True (as it should be), but then my threads stall on the Me.Invoke statement - pausing execution shows them all just sitting there, not actually invoking anything.
Arithmetic Overflow Error ?
Apr 19, 2012I'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.

Multithreading - Cross Thread Invoke From Class?
Jan 24, 2012I am making use of a serial port in a class. I am raising an event from that class to my form calling the class. Event contains data received... I wish to simply populate a textbox from the raised event.Now I am not specifically creating a seperate thread, but I get the normal crossthreading error when trying to update my textbox on the UI, so my assumption is that the serial port and its internal methods probably creates its own threads...Regardless, I am a bit confused as to how to properly implement an invoke, from my main form, pointing to the thread in the instantiated class...

Multithreading - Limit Time An Operation Can Take
Dec 18, 2011How can I limit the length of time an operation is allowed to take?
I have an external library that processes image files. I'm running it against thousands of images, and every now and then the library gets stuck on certain images. If I need to skip an image here or there, no problem, but I can't have the process get locked up, so I want to impose a maximum amount of time that the process is allowed to take for each image before I force it to give up and move on to the next image.
Cross-threading Operation Not Valid Even Though Invoke Is Used?
Sep 28, 2010I've been reading around trying to find out why I'd be getting this exception to no avail.
I'm using Visual Basic 2010.
Briefly, I have a "Settings Panel" form which takes a while to create (it contains a lot of labels and textboxes), so I create it in another thread.
After it's loaded, it can be viewed by clicking a button which changes the form's visibility to True. I use the following subroutine to handle invokes for my controls:
Public Sub InvokeControl(Of T As Control)(ByVal Control As T, ByVal Action As Action(Of T))
If Control.InvokeRequired Then
[Code]....
The SettingsTable.Create() method generates a bunch of Labels and TextBoxes based on the contents of the application settings and adds them to the SettingsTable.
When I click on the ViewSettingsPanel checkbox, I get a cross-thread violation error.

View 9 RepliesIllegal CrossThread Invalid Operation Exception On Form.Invoke()
Sep 12, 2009Got a proccess thread thats in charge of loading a listbox full of the first line of text for richtextbox items on form load. Though I use Me.Invoke(New MethodInvoker...) to add items on the main thread so its thread safe it coughs when the first line of rtf data are thrown at it, acting as if I hadnt called adding the items on the main thread.
Up at the class level:
Dim Worker As System.Threading.Thread
In the load procedure for the form:
Worker = New System.Threading.Thread(AddressOf WorkerDo)
Worker.Start()
[Code]....
I"ve also tried to remedy this using a delegate to invoke the listbox before attempting to update it, but the invoke method itself is throwing the exception. I am not using the default instance of the form (a new instance of this form is created). Anyone know how I can get around this? I can't load the listbox full of items directly in the form's load procedure because work takes place in the thread beforehand so there are strings to add to the listbox. I've got MS Visual Studio 2008 Pro and Vista SP2 (latest updates applied).
