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.
View 1 RepliesWhen 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?
View 24 RepliesI'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.
I have been testing with logging into my websites using httpwebrequest, i have done it great, but 1 of my sites requires a captcha to login:

View 5 RepliesIm using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...
Private Sub getMessage()
For infiniteCounter = 1 To 2
[CODE]...
And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.
this is probably easier than I think it is.I would like a client-to-client messenging system without using Winsock if possible. At the moment an IP based connection system would be okay.
View 8 Replieshow to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])

i have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.
[code]....
i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??
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

View 4 RepliesI 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

View 7 Repliesi 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 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.
