Extract A Large Number Of URLs From A Site?
Dec 18, 2010
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 have to extract all there is between this caracters:
<a href="/url?q=(text to extract whatever it is)&
I tried this pattern, but it's not working for me:
/(?<=url?q=).*?(?=&)/
I'm programming in Vb.net, this is the code, but I think that the problem is that the pattern is wrong:

I have a system which needs to be secure which streams relatively large documents from a webservice to a proxy (Web site) whch then grabs the stream and pushes this to the client. This works but there are some issues where it seems the response is not being pushed until the entire stream is complete? whether this is the case Im not sure have run charles and until it completes it is "Waiting for response".
The documents are currently PDF but it needs to handle many other types for the future. The octet stream etc is mostly testing related, how to get the Dialog to show - saying save as? for the large files the little ones don't matter to much but the big ones leave a big waiting period with no response.
Dim IncomingResponse As HttpWebResponse = DirectCast(Request.GetResponse(), HttpWebResponse)
Dim IncomingStream = IncomingResponse.GetResponseStream()
Dim BufferSize As Integer = 65536
Dim Buffer(BufferSize) As Byte

Is there a simple way (a public library/class perhaps) to get the number of backlinks for a site from Yahoo API? (yahoo boss. yahoo site explorer) Preferably in vb .net?
If not, is there a library that allows easy access to the Yahoo API, like Zend Framework provides for PHP equivalent?

I am using VB Express 2008 and want to return the titlebar text of a window This is what I have:
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long
Private Const WM_GETTEXT = &HD
Private Const WM_GETTEXTLENGTH = &HE
[code]....
This should simply return the window name I.e. "Calculator"But debugging it i get an "OverflowException" on:
strtmp = Space(length - 1)
If I look in the length variable it has "8975925931411505153" in it Why is it so big, and why is it not just "10" for the number of characters in calculator?

I am using zipforge.net to archive files in a small backup program I am creating. Everything works fine however if I try to archive a large number of files the process of zipping them gets slower the further along in the job it gets.
Example: I have a directory that contains a little over 100,000 files in it. Each file is only about 200k of text. When I use the zipforge zip class it starts zip'ing very quickly but as it gets about 40% of the way through the directory it starts to slow down... at about 60% its working at a snails pace.
Memory usage for my solution also goes up proportionate to the archive file size as it grows. Currently it takes around 26hours to backup this directory which only contains 4 gigs worth of information.
If I use a program like winzip I can zip the folder in less than an hour. I am thinking there has to be a way to write to the end of the zip file without having to open it every time or without keeping it open. My backup software scans the specified folder and writes each file path and name into a text file. Then it reads the text file line by line and passes the path + file info to the zipforge addfile().

I know this is probably a stupid question. I am converting a huge string to a integer, it is not working.....saying the number is too large to handle. It is only a 10k character string.I figured this would be fine because 2^16 power is 18446744073709551616.

I'm working on a project that involves localizing a large number of Windows Forms. We're dealing with layout using the TableLayoutPanel control, which works nicely. One area we're striking problems with is when we set the Form.Localizable property to True, we then end up having to manage one .resx file per form per language.
That would be fine if the .resx files only contained the Localized text, but it also contains a vast amount of layout data for the form. Is there a way to separate the localizable text elements from the control layout information, that continues to work in the visual studio IDE? I've noticed that I can modify my the form's designer file to look at another resource file, but when I use the form designer, these changes are deleted:
'Label1
Me.Label1.AutoSize = True
Me.Label1.Dock = System.Windows.Forms.DockStyle.Top
Me.Label1.Location = New System.Drawing.Point(3, 0)
Me.Label1.Name = "Label1"
Me.Label1.Size = New System.Drawing.Size(61, 13)
Me.Label1.TabIndex = 1
Me.Label1.Text = My.Resources.ResourceManager.GetString("Form1_Label1_Text")

I wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.

I have a question about how to get a button to check for a textbox contents, and then compare that with data in my fairly simple database (It's meant as a login procedure).
Here's my database:
It has 2 values, 1 for the manager and 1 for the Admin
Here's my Login screen:
Now...
Everything works just fine, all the code is correct so all the buttons work. For the program i'm making, there's 3 types of users, 1 user who can only change how much money a customer owes the company, 1 user that can add new customers and other little things and one Admin who can change pin numbers and manage backups and stuff like that. For the last 2, i need pin-number/password protection obviously.
The user should enter the pin and then press ok, after which the ok button checks if the pin number the user entered, corresponds to either identifier 1 or 2 (5566 or 6655 for now) and if correct, show the user the next form.

We have a customer, who prints a large number of a batch job to a reporting service. When printing large batches of jobs, occasionally he would get a WebException from reporting services saying "The underlying connection was closed".What is the work around for this? Somebody added this portion in the code [code]It doesn't seem to fix the issue though. The customer still notices the Web Exception when she prints a large job to reporting service.
