I modified some code to suit one of my other programs, but have come across a difficulty: For some reason, the output file is not outputting.

I've a situation where I am trying to extract a large number of URLs from a site, but the site which provides the URLs has an obstacle. Rather than the link directly to the site, they provide a link to an internal page, which automatically redirects me to the URL I need.
i.e.
<a href="www.StartingSite.com/outgoing/1234" ...> Example.com</a>
which passes me to an internal page, then automatically routes me to Example.com
I've suspected if I can do this, it would be through cookies.
Perhaps a little more work, I could create a page which calls each page, then I could acquire the URLs from my history, but my browser would crash for the # of URLs I'm extracting.
any means I could gather the end URL of this link?
I'm currently trying to extract an image from a pdf file using iTextSharp.
The pdf is made from a scanner: it has a single page that contains one big image.
When looking at the file I find the following:
<< /Type /XObject /Subtype /Image /Name /Obj3 /Width 2480 /Height 3507 /ColorSpace /DeviceGray /BlackIs1 true /BitsPerComponent 1 /Length 5 0 R /Filter /CCITTFaxDecode /DecodeParms << /K -1 /Columns 2480 >> >> stream
[Code].....
But, that doesn't work as I get one big black tiff file with different shades of gray on top.
Does anyone know a way how I can decode those CCITTFaxDecode images?

I need to generate dynamic URLs from a database in code behind and then use them in a list view but i cannot find anywhere on the internet or in my book that covers something like this.

I have a list of 100,000 urls in list(Of string) which can contain urls in the form. [URL] i have tried using a combination of regex and the Uri class, but that didn't help, so i dumped the code. How do i filter these duplicates and keep just one of these url
View 8 RepliesLast month (i think) i needed help with regex which i used to find MP3 urls in the source code of a site.Now the code doesn't function properly
[Code]...
I need to find .MP3 format URLS in a HTML source code.So how could i do that?Lets say i have:
Dim wcClient As New System.Net.WebClient
Dim data As System.IO.Stream = wcClient.OpenRead(inbox.ToString)
Dim reader As System.IO.StreamReader = New System.IO.StreamReader(data)
reader = reader.ReadToEnd()
reader.Close()
so how could i find all the .MP3 urls which are in the source code?
I've found some examples using RegEx but im not really sure how to use the RegEx pattern to find MP3 urls in the source code.
I need to create a number of barcodes as images on a page from a set of UPCs from a database.Additionally, I also want to be able to produce barcodes which can print as labels to a Dymo LabelMaker.Googling turned up several options, but it seems that for the LabelMaker it'd be wise to produce the barcodes as PDF? So, I started looking into iTextSharp which seems good (and free!)Looking fora simple way to render a Barcode Image to a page, I found this, which looks to do exactly what I want, but I can only get it to work locally. When uploaded to the server it just shows an empty image.I have checked and double checked the web.config file contains everything required and am pretty sure that Adobe Reader is installed on the server (as was suggested by another post in the link). There's a post in the link which says
I just wanted to put a small update for those running IIS7, if everything works fine when running locally in VS debug mode, but you get a red x when accessing it remotly, you may need to add the handler in the section as well as/or the i.e.Which sounds like it's answering the problem but doesn't..url...Part 2 of my question is, am I heading down the right line to print the individual bar codes to a LabelMaker by using iTextSharp?
I'd like to know if there are other ways to write a submission program (submitting urls or pad xml to directories, submission sites, blogs) other than using the webBrowser. I've evaluated some shareware programs that submit urls or data very quickly, like 100s in a matter of mins. I couldn't write a program using a webBrowser because it might take 15 secs just to load the url. How are they writing the code??

I have a company Website in Visual Studio / VB / ASP.NET 4.0. I noticed a competitor of ours also has .aspx extensions in their website. They have strings at the end of their website URL. For instance, when you click a language, it has this after the dot com:
/main.aspx?langtype=2057&locale=en-be
And of course it goes to that language/culture and the "be" is, I assume, the uiculture/subculture.But how do you get these strings in your own URL?
I'm trying to write out animals from a database. All the samples I see for creating View pages have hard-coded "nodes" in the URLs. I can get my first view to work but my second one doesn't write out the correct URL to go to the third one. So, for example, I want my URLs to be:
/animals/
/animals/canines/
/animals/canines/schnauzer
I have the default route setup:
> routes.MapRoute( _
> "Default", _
> "{controller}/{action}/{id}", _

... I'm guessing I'm missing something in a route path but what is it? It can't be that I have to know the path I'm at on every page in order to write out the URL - can it?
