CaptchaRecognition - parameters

[zennmike]

Hi,
I think, I have problems with sending additional parameters to DeathByCaptcha (I want to recognize ReCaptcha2). The picture which I send is ok, this already i have checked. But I still got strange answer like some letters like "kk", "lkk", "picture". Answer "?" means that picture which I send is incorrect, but when I check on their site, it seams ok. So I assume that I send wrong parameters. (when I contact with deathbycaptcha, they sad that I use bad API, but API which You atached to Zennoposter work correct with diffrent type of captcha - of course without additional parameters).

Example below
In Project Maker

In Code Creator

ZennoPoster.CaptchaRecognition("DeathByCaptcha.dll", JpegBase64String,
"type=3&banner_text=Select all images with rivers.&grid=3x3" );
My question is:
1. Is this form of sending additional parameters are correct (what about white spaces)? If not, can You post example? What I do wrong?
2. Adding more parameters is the same for diffrent type of of captcha recognized modules, like AntiCaptcha, etc.?
3. Can I send text of question to MonkeyEnter.dll, and it will be visible on popup window with picture?

1-2 parameters should not have white spaces.
This seems correct: type=3&banner_text=Select all images with rivers.&grid=3x3
3) no

 

[zennmike]

type=3&banner_text=Select all images with rivers.&grid=3x3
So if there shouldn't be white spaces, that I should correct upper text for like this:
In Code Creator
1. type=3&banner_text=Select&#32all&#32images&#32with&#32rivers.&grid=3x3
or
2. type=3&banner_text='Select all images with rivers.'&grid=3x3
?

 

[rostonix]

i think
type=3&banner_text=Select all images with rivers.&grid=3x3

I think I found some idea.
On site http://www.deathbycaptcha.com/user/api/newrecaptcha write that to solve recaptcha, or recaptcha2 we need to use form like this.

if we use original API (I try but it's not want to work with zennoposter)
Captcha captcha = client.Decode(captchaFileName, timeout,
new Hashtable (){
{ "type", 3 },
{"banner_text", "Select all images with meat"},
{"banner", bannerFileName},
{"grid", "4x2"}});

So I try to do:

answer = ZennoPoster.CaptchaRecognition(captchaModule, JpegBase64String,

new Hashtable (){
{ "type", 3 },
{"banner_text", "Select all images with meat"},
{"banner", bannerFileName},
{"grid", "4x2"}});

but there is error "cannot convert hashtable to string" which is obvious.

Question is:
1. How to write/convert type Hashtable to string, that deathbycaptcha will see it as good parameter?

 

[rostonix]

// search for element with captcha
HtmlElement he = instance.ActiveTab.FindElementByTag("form", 0);

// send it to service
string res = ZennoPoster.CaptchaRecognition("DeathByCaptcha.dll", he.DrawToBitmap(true), "type=3&banner_text=Select all images with rivers.&grid=3x3");
return res;

The picture is not a problem, but parameters. I checked it on DBC.
Unfortunately I can see only what picture DBC get, and answer from them.
Example below

When I'm sending like this:
ZennoPoster.CaptchaRecognition("DeathByCaptcha.dll", JpegBase64String, "type=3&banner_text=Select all images with front of shop.&grid=2x4");

JpegBase64String is variable with picture in Jpeg converted to Base64String.
grid is alway corect recognized

answer from DBC:"stop"

They realy often answers are: "kk", "lkk", "picture" or similar.
sometimes i get answer "?" - which means that picture is incorect, but when I go and check, the picture looks ok. So I asume that the parameters are wrong.
I rarely get good answer which should look like that "2,3,4,5".
When I contact with service, they said, that it's problem by software side.

So I read more and found that for Recaptcha2, they use difrent form of sending parameters, by using Hashtable (it's in original DBC api in C#).
I try to implement it in Zennoposter:
answer = ZennoPoster.CaptchaRecognition(captchaModule, JpegBase64String,
new Hashtable (){
{ "type", 3 },
{"banner_text", "Select all images with meat"},
{"banner", bannerFileName},
{"grid", "4x2"}});

but there is error "cannot convert hashtable to string" which is obvious because in ZennoPoster.CaptchaRecognition, parameter is string type.

Question is:
1. How to write/convert type Hashtable to string, that deathbycaptcha will see it as good parameter? Or how it should by writen in string? because I asume they use post or get method, so they can only send a string, not variable like Hashtable.

2. Or maybe someone have working example?

I found whats wrong, but it's by Yours side.
Like someone from DBC said, that's problem by Yours side. You have old DeathByCaptcha.dll library.
Look for the size of file.

When I'm changing Yours original file for this from DBC. My C# code work good.

But then Yours original element

from Project Maker not working, if there is chosen "DeathByCaptcha.dll".

When I'm trying to fix it, by:
- remain original file deathbycaptcha.dll in catalog progs
- and then adding GAC reference with new DeathByCaptcha.dll library from DBC.
This also not working, because I think the "namespace" in both file are the same, and when I'm calling

DeathByCaptcha.Client client = (DeathByCaptcha.Client)(new DeathByCaptcha.SocketClient("xxxxxxxxx", "xxxxxxxxxx"));

It's call original (old from Project Maker) library, not new from DBC, which I try to include.

Question:
1. How to fix it?
2. How to read user name, and password of service for example DBC, without reading file DeathByCaptcha.dll.config?

 

[rostonix]
