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.

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

Application.StartupPath & "PatchData.dat": PatchData.dat isn't created yet, but my program makes PatchData.dat, and PatchData.dat is ~8KB when my program gives me this error.
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".
View 6 RepliesI 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..

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.

View 2 RepliesI'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:

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 have some software written in VB.NET that performs a lot of calculations, mostly extracting jpegs to bitmaps and computing calculations on the pixels like convolutions and matrix multiplication. Different computers are giving me different results despite having identical inputs. What might be the reason? I can't provide the algorithm because it's proprietary but I can provide all the relevant operations: [code]Is it possible that OrderBy is using a non-stable QuickSort and that QuickSort is using a random pivot?

View 1 RepliesI am writing my own script for a simple calculator that determines if a number is prime, and its prime factors.[code]The loopcount = compare - 2 means I want the loop to be 2 less than the square root of the answer so that when do a descending calculation (loopcount = loopcount - 1) it doesn't see if 1 or 0 is a factor of the answer. for the calculations after that, I want, every time n1 = n2 (a whole number factor of the answer), I want to report those results to a text file (n2 and n3) in this format "(n2, n3)" then go to the next line. and continue to execute the loop until the loopcount is zero. Currently, when I run the code, the application closes when I click the prime button (button that runs this code) and I don't know why. This is my first semester in school, and have never coded before, so I am a definite laymen with code, but I really really want to learn it (hence why for fun im just creating algorithms for different things).

I'm trying to create an event handler for a graphic elipse, so I can do the math in a separate "control box". There will be multiple graphic elipses feeding the TextBoxE1 box. ( As for all the note textboxes.) This is a graphic creation of a guitar neck that will tie to a 2 table database. Click on a note & it will be identified, a series of notes will call on the related scales from the database. The problem is that I need to create an event handler for each graphic elipse so the code won't fire unless the elipse is clicked on. If only one elipse in that keynote value is clicked, it will put a "1" in TextBoxE3. TextBoxE1 & TextBoxE2 will be hidden.
TextBoxE1 value = "0" until at least one "E" is clicked. ( Elipse that is valued as "E".)
TextBoxE2 value = "1"
TextBoxE3 value = TextBoxE1 + TextBoxE2
