PHPLd Submitter using HTTPWebrequest

SEOboss · Jan 15, 2012

I am automating form of following web sites using HTTPWebRequest in vb.net

Code:
http://www.ignite400.org/submit.php,
http://www.tradingyp.com/submit.php
These sites are having dynamic captcha & these captcha get changed for every http web request.

what I want is submit request happens, the captcha image should pop in a small window and I wanted to enter the captcha and click ok, then it should submit to the site.

showing captcha image on box is not ptoblme but the problme is captcha gets changed on request & page gets refreshed

any way to keep same captcha with out refersing using httpwebrequest

The first site is very easy. It simply generates a hidden hash which can be used only once.

parsehashvalue = "><input id="IMAGEHASH" name="IMAGEHASH" type="hidden" value="672143d5fc04dc6408cb984451491fae"

downloadfile("http://www.ignite400.org/captcha.php?imagehash= + parsehashvalue"

I'm not sure what your issue is with the second site because to receive the captcha you simply have to request http://www.tradingyp.com/captcha.php

As I have already stated, the hash value is only valid for _ONE_ request. You can't open it in your browser if you have already requested it in your application.

1st send Webrequest to the page & grab the source then run Regex

Code:

<img src="[^"]+

Replace the <img src=
you will get Captcha Value which will be valid for One time and use it in Submitting the Data..

Form1.vb:

Code:

CaptchaForm.PictureBox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(CaptchaImageURL)))
                CaptchaForm.ShowDialog()
                CaptchaAnswer = CaptchaForm.TextBox1.Text

CaptchaForm.vb:

Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Me.Close()
    End Sub
