I'm just wondering about making a downloader like IDM, we all know how it works right?well, just wondering it how did they implement like"Chopping / Splitting " files to download - They do have each a starting point.then merges the files?

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 need to make a downloader.EXAMPLE:I have a file that i uploaded to a ftp, i want to make a file that when a person presses "DOWNLOAD" the file starts downloading to a directory he selected.

I was just wondering if I could create a simple downloader created using VB 2008. The user will enter the complete address of a file from the internet, click the Download button then the downloading process will start. There should also be a button labeled "Paste" which will paste a valid path (copied into the Clipboard) into a textbox .

View 3 RepliesI'm having a bit of a problem with my if statement on my browser downloader checked list box at the moment.
This is happening: If the selected item is "Google Chrome" Then a textbox's text should be "Google Chrome".
I want it to be: If the checked item is "Google Chrome" Then a textbox's text should be "Google Chrome".
My current code for this is:
If boxBrowser.SelectedItem = "Google Chrome" Then
devbox.Text = "Chrome"

How the logic is confusing. I was thinking of making a Variable that stores the time NOW and once the uploads 1 file, another variable will take the time and subtract it from the old time and times it by the number of files left. Or as you can see I have a little % calculation there and I could use that to calculate the amount of time left.Will that be consistent? Or are there other ways to achieve the result

Update: the form 1 would have a image button that opens a form thats form would act like a window. like the ones you use when you open up a folder on your desktop. but it would minmize into the form 1 as an image button caching its info so you can pop it back up.

I want it to ask for a file location first, and then next time pushing the button "start" it remembers the location ?

i want user when clicks a button to show a selection around a richtextbox and not inside it selecting the text... what i have right now is this: richtextbox1.focus() that will indeed focus the richtextbox but the problem is, it only selects its text content.
What i want is something similar to a Yellow or Blue Square showing around the richtextbox i want to "select", so the user will properly notice the richtextbox more easelly.
i tried messing with the vb express rectangle stuff but i cant get it to draw over all objects, its actually always displaying below all objects in the forum

View 5 RepliesI am making a array (unknown value) into a grid for a game of pairs (where you must get both of the cards). So far I have specified the array to a specific size of either 6, 6 10,10 or 16, 16. using a button. The selection is defined from the button as specified before
Dim NumberOfCards(Selection) As Integer
Dim NumberOfCards(Selection) As Integer
Now I have a panel box which I want to add the number of rows / columns as the array sizes which I cannot do. But also add a image specific to all of them.
I've been trying to make a grid to test some AI stuff I'm working on. I managed to do it using rectangles and graphics.rectangle (pens.black, rect) by using a vid on youtube, but it made the application virtually useless because of all the memory it was using. I don't need it to be an actual grid, but I do need it to have values as if it was a grid, so that I can issue commands (x,y coords). (I have been searching the forums for over an hour, but all examples are either useless or cant be converted correctly).
