Communications :: Downloading Random Text File From Server
Apr 23, 2009
I'm working a program, which will download files from my server. But I need, program will download random files from text file on server, for example: I have [URL].
In links.txt are these links:
[URL] .....
If I run a program, it will download first link, after finish download it will download fifth link, second link etc. Downloading of one link works fine for me, but I need download more links...
Code:
theRequest = WebRequest.Create("[URL]")
So I need: theRequest = WebRequest.Create("RANDOM LINK")

VS 2008 SP1 I am using the web client to download a file. Which works ok.However, now I have to download many and the number of files to download will change everyday.I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download?The web client could download the same file twice?
Private Sub btnStartDownload_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim client As New WebClient()
AddHandler client.DownloadProgressChanged, AddressOf client_DownloadProgressChanged
AddHandler client.DownloadFileCompleted, AddressOf client_DownloadFileCompleted

I am creating a ASP.NET (VB.NET) application that must retrieve a known remote file and return it to the visitor through their browser. I am attempting to use the sample from Microsoft located here: bid=812406 and running into an error 'This stream does not support seek operations'. I'm not sure how to proceed.Here is the code with the error line marked.
Dim ftpWebReq As Net.FtpWebRequest = CType(Net.WebRequest.Create(path), Net.FtpWebRequest)
ftpWebReq.Method = Net.WebRequestMethods.Ftp.DownloadFile
ftpWebReq.KeepAlive = False

For some odd reason, when I download text files, the HTML of the web page is being appended to the text! All other file types work fine!Here's the code that's doing the download:
Public Sub DownloadBlob(ByVal Blob As Byte(), ByVal FileName As String, ByVal Response As HttpResponse)
Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", FileName.Replace(" ", "_")))
Response.ContentType = String.Format("application/{0}", Path.GetExtension(FileName).Substring(1))
Response.BinaryWrite(Blob)
End Sub

I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

I am writing a program to calculate Pi to several hundred billion decimal places and this will require lots of GB of memory. I wrote a test program in VB2008 that saved the first 16 digits of Pi (without the decimal point) to both a text file and a random access file, just to be sure it was outputting the numbers properly. For reference the first 16 digits of Pi are:

I have a text file that includes a list of first names, each on their own separate line.
What I am trying to do is to find a way to click on my button and have my app open the list and randomly grab a name and place it into a textbox.
I would include some code but I'm not even sure where to begin.
I'm thinking that I will need to code the button to use the openfiledialog..create an algorithm to use a random copy line and return it into the textbox.

My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

I got a little program that generates a random line of text from a .txt file and all is working well, at least for the most part.
On occasion I get an error message popup saying "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: Index."
Here's my code:

The last bit is where the random number is generated, which I am guessing where the problem itself is, but am unsure as to how to fix it...

The &H30D? i know its a hexadecimal value and may represent a message but i cant find anything about why someone would need to use one, and not just "As Integer = 703". I've found nothing in the VB.NET library or windows messages/functions docs.

For my next project i'll have to create a TCP or UDP server based application. I know how to program a server but i am interested on the limitations of such servers.
how many connections a server may be able to handle at the same time. I suspect that this limitation is based on the type of transfer and how much data or how often it is send to the server.
I also read somewhere that a windows program is limited to 25 threads (connections) per core so if i would have a quad core i can have a maximum of 99 connections granted that the server itself is also a thread. Is that correct?
If the above is correct i wonder how to handle let's say 200 users at the same time. There must be some form / way to handle bigger request loads.
