Download Form - Arithmetic Operation Resulted In Overflow
Aug 16, 2010
I am having a problem with a download form I am trying to make. This downloader works fine for small files but once it gets to, 20,969KB it errors, "Arithmetic operation resulted in an overflow". I downloaded this code about a year ago and used it in all my applications for my auto updater I have coded for my applications....
Downlaoder code...

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

If byte1 <> byte2 Then
OffSetFS.WriteByte(offset)
OutPutFS.WriteByte(byte2)

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..

If dgCell = "Delete" Then
'make sure user wants to delete the selected record.
If MsgBox("Are you sure you want to delete this image?", MsgBoxStyle.OkCancel,
[Code]....
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'm not sure if this is problem with the database or vb. I get this error when I run the delete above, also when I run an insert or an update.

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.

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.

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'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.

I am running several long synchronous operations in my VB.NET application that can take several minutes each to complete. During these operations the form will turn white and the title bar will show "Not Responding" and some users may close the application thinking it has stopped working when in fact it is still running.I am pretty sure I need to multithread to do this, but my initial efforts have been unsuccessful. What is the easiest way to refresh my form every couple of seconds or so while these long operations are running?
