I have always used the API for Vb.net from Decaptcher.com and have always sent the Captcha by sending an actual url to them as you see in the code below. Or maybe it uploaded the image anyway to them (I use the Webbrowser Control) I'll use for example this:

Code:

Dim dr As DecaptcherResult = DecaptAPI.GetCaptchaSolved(Me.WebBrowser1.Document.GetElementById("captcha_image").GetAttribute("src"))

But with the current project that I am working on right now I am having to take a screen shot of the captcha image, then save it to my harddrive.

I know that through your API Decaptcher allows us to upload the image from our harddrive but I just can't figure out how to use the code to do this. I have tried this but it doesn't work:

Code:

Dim dr As DecaptcherResult = DecaptAPI.GetCaptchaSolved("c:\1\Untitled.jpg")

Can anyone please tell me the proper code to send the image and get the response.

Thank you so much

BELOW THIS IS THE CLASS AS WELL WITH THIS.
THANK YOU SO SO MUCH TO WHO EVER WILL HELP ME WITH THIS, IT MEANS SO MUCH TO ME.

You do realize you posted your username and password in the code, right?

Its just a made up one.

i am also having a problem,,

the decapture.dll seems to be written in vb 2003 and im using the vb 2008,,

did you get it to compile in visual studio 2008? and if so ,, i cant seem to reference the decapture.dll in mine,, do you have a copy of one? and or are you using the dll at all?

Edited 6 Years Ago by Nick Evan: snipped mail
