Download - Calculating Speed And Time Left (Progress Bar)
Feb 5, 2011I created a software which download files from the web. I also added a progress bar which shows the download progress. Every thing works fine.
Now:
- How can I add a label that will calculate the time left for the file to be downloaded and another label that will tell the speed of the download?
- Would it also be possible to add a label which calculates the size of the file that is begin downloaded?
Here is what I declared:
Imports System.Net
Public Class Form1
Dim WithEvents Download As New WebClient
Dim WithEvents Download1 As New WebClient
Friend WithEvents Label1 As System.Windows.Forms.Label
Here is what I have under the download button:
Download.DownloadFileAsync(New Uri("URL" & ComboBox1.Text & ".rar"), Textbox1.Text & "" & ComboBox1.Text & ".rar")
And here is what I have under Download_DownloadProgressChanged:
ProgressBar1.Value = e.ProgressPercentage
Label1.Text = e.ProgressPercentage & "%"
If ProgressBar1.Value = 100 Then
MsgBox("Download Completed!", vbInformation, "Info")
Label1.Text = "0%"

View 5 RepliesVS 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.

Sep 19, 2011I need to create a simple program that will calculate de price of the meal+the taxes aswell as the tip.
The prov taxe= 8,5%
the fed taxe = 8%
and the tip is 15%
I need to use const for this one.heres what i came up with:
Private Sub partie4_click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles partie4.Click
Dim repas As String
Dim sous_total As String

The user has to type the price of the meal and then it should calculate the price but for some reason instead of *8,5% it will do x*8.5.

Oct 19, 2011I am trying to calculate the difference between 2 times.
So far I have 4 labels.
Label1 = Current date and time.
Label2 = Contains the exact time that the application was last closed.
Label3 = Contains the exact time that the application was opened.
Label4 = I want this label to say how much time in seconds had elapsed between the application last being closed and the application being opened again, in other words the difference in seconds between label 2 and label 3.
Below is what I have done so far, but despite repeated efforts I can't seem to find a way of getting the time difference to show in label 4?

VS 2010 - Speed: WebClient Versus Socket
Apr 25, 2012I make a lot of programs that require an internet connection to download things from the web.At the very beginning, I used WebClient, as I didn't know Socket & how it worked.But now, I use Socket all the time, altough it's more lines of code. It seems to work faster then WebClient.I am interested if this is really true & why WebClient is slower (so is HttpWebRequest) then just a Socket.I've setup 2 threads which starts on the click of a button (WebClient thread starts first), the Socket beats the WebClient by just some milliseconds, but still.Each way has it's advantages & disadvantages, e.g.: if you use Socket, you need to write the header yourself & parse the response header.My question is, which one do you prefer & why ?Do you know why WebClient & HttpWebRequest are slower then Socket, as I assume, WebClient & HttpWebRequest both use tcp to download the things.

It involves a lot of cleanup and parsing but on average it takes around 6 seconds per post.
