When you reach a captcha while creating accounts on some sites, is there code that would make the program pause and a message box pop up that would ask for input for the captcha code?

Some sites have captcha images when you sign up for them. I want to take that captcha image and put it in an imagebox so that a person can put those characters in a textbox and then the form will submit the captcha text to the site.Example: My application has a webbrow ser which navigates to here from there i want the captcha image to be put in my other form which will have an picturebox.Code so far:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have an app that will sign me up for about 20 websites at once and each one requires a captcha to prove your human (which is cool I don't mind typing them in). I have a form 2 that is going to pop up with all the captchas viewed in picture boxes with textboxes for me to enter my text and submit buttons to enter the captcha to the website.The only issue that I am having is getting the captcha to view in the picture box. It refreshes everytime I get it to showup.I had it working previously but my hard drive crashed and I lost the code and the app.From what I was able to put together previously I was able to grab the element by type and if the src had [URL] then to put the source into the picture box.I tried to rework it all day yesterday and I just keep getting the code refreshing.
Here the code.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("https://secure.diigo.com/sign-up?referInfo=http%3A%2F%2Fwww.diigo.com") 'Website that has the ReCaptcha
End Sub

I'm playing a simple textbased game. And then I thought why not try to create a bot. But there's one problem. A CAPTCHA...But this captcha is very simple. It's 3 random numbers wich always uses the same font, size etc.For the simplicity we can say that it uses 9 different images and randomly puts together 3 of em.I then remembered a client for a java game that matched images with text on the screen to read the text.How can I make a program that does something like this:
if imageA.bmp exists on screen then
captcha &= a
End If

I'm making an image uploader for a site but sometimes a captcha from [URL] appears? Is there any code I can use so when the captcha appears, a box with the captcha image appears so I can manually solve it? I've seen some programs that do it so i know it can be done...

i have an aspx web form with vb code behind. the form is a simple input form with a table with textboxes and a submit button. i am looking to be able to insert a captcha image into the table with an entry textbox and check the value entered against the image on the submit button.
i have found various 'helpful' bits of code on the net to explain how to generate the image. but none of them explain exactly how/when the image would get generated, how you can insert the image onto the webform where you want it to be, or how you can check the text input against that image.

I'm working on adding a de-captcha into one of my programs but I can't seem to be able to grab the captcha from the web browser.I don't think I can just parse the URL and use webrequest to download it as it'll be a different string once it's reloaded.

I made an email account today and out of curiosity I was wondering if this is possible. Is it? Has it ever been done before? How is it even possible? I mean, all that spam email I get, it must be generated emails doing that because even though I "mark as spam" it, I still get the same email but from another address.

I'm trying to figure out how to prompt a user to enter a captcha. Some programs out there have a little popup with the captcha image and a textbox, the user then enters the characters from the image and the captcha is solved by the user of the application. When I try to request the image directly, it gives me a different image than the one currently in the webbrowser control. Any ideas how I can create the pop up of this captcha image for the user to enter?
Note : . I'm looking for a way to prompt the user to enter a captcha from website.

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

I want to capture Form1 window, not what is on top (what I actually see).
Dim screenshot As System.Drawing.Bitmap
Dim graph As Graphics
[code]....
It captures what is on top, for example: I have firefox on top, so in myPic.bmp will by firefox, not Form1 window. So, how can I do that when some programs are on top, it captured Form1 window?
