Windows form application wont work on another PC

I created an windows form application that goes to a website and does a HTTPwebrequest POST and then displays the result in a webbrowser. I tested it on the computer that I wrote the program on and it works exactly like it should. However when I get the .exe file from the bin folder along with htmlagilitypack.dll and run a test on another computer, it does the POST data but web page that shows up in broswer is just the default login page. I have looked at it on fiddler and it seems like the cookies aren't getting set to the webbrowser. How can I fix this? I have also compiled the program in release mode and transferred the files in the release folder and its the same result.
On the program I used this to set the cookie for the browser.
[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
static extern bool InternetSetCookie(string lpszUrlName, string lpszCookieName, string lpszCookieData);
Does it have to do something with that dll file?
Edit: I have made sure both computer has 4.5 NET installed.

Sow here is the promleb after this i doing the new redirect to page but as you see cookies is empty and i get stack.Any ideas?
I just find out that in postResponseAfterLogin i have this function in side of code with my link that i need and timeOut(2000).This can help to resolve this problem?
<script type="text/javascript">
//<![CDATA[
getLoader_Side(); function loginRedirect() { setTimeout("UpdateLoaderImg()", 50); top.location.href ="https://services.test.com/Pages/Trans.aspx";} setTimeout("loginRedirect()", 2000); var _spFormDigestRefreshInterval = 1440000;Sys.Application.initialize();
//]]>

Use for the second request
postRequest.CookieContainer = request.CookieContainer;
This will use the cookies of the first request.
Otherwise, you must set the right URI when you add the cookies manually
http://msdn.microsoft.com/en-us/library/ckch3yd2(v=vs.110).aspx

You can try the cookie aware web client like the below one:
https://gist.github.com/paigecook/5221158

Try using Static Methods:
For save:
HttpContext.Current.Response.Cookies.Add["MyField"];
HttpContext.Current.Request.Cookies["MyField"];

how to display image directly from httpwebresponse stream in asp.net?

I want to display image recieved from webresponse to browser directly without saving to a file.i have used below code to save the image to file but i want to display in browser directly.the website provides the captcha image in webresponse which i want to display.please help me.
public void captcha(string id, string pass)
{
HttpWebRequest req;
HttpWebResponse response;
string strNewValue,ckuser,ckpass;
System.Drawing.Image returnval;
ckuser = id;
ckpass = pass;
this.req = (HttpWebRequest)WebRequest.Create("http://site2sms.com/security/captcha.asp");
ServicePointManager.Expect100Continue = false;
this.req.CookieContainer = new CookieContainer();
this.req.AllowAutoRedirect = false;
this.req.UserAgent = "Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0";
this.req.Accept = "*/*";
this.req.Method = "POST";
this.req.CookieContainer = cookieCntr;
this.req.ContentType = "application/x-www-form-urlencoded";
this.req.Referer = "http://site2sms.com/verification.asp?source=login";
this.strNewValue = "user=" + ckuser + "&password=" + ckpass + "&Submit=Sign+in";
this.req.ContentLength = this.strNewValue.Length;
StreamWriter writer = new StreamWriter(this.req.GetRequestStream(), Encoding.ASCII);
writer.Write(this.strNewValue);
writer.Close();
this.response = (HttpWebResponse)this.req.GetResponse();
returnval = Image.FromStream(response.GetResponseStream());
// returnval.Save( Server.MapPath("captcha.bmp"));
Response.AppendHeader("Content-Disposition:", "inline;filename=captcha.bmp");
Response.ContentType = "image/bmp";
Response.Write(returnval);
Response.End();
this.response.Close();
}

You can use HttpResponse.WriteFile method to send the stream to client directly.
Writes the specified file directly to an HTTP response output stream.
You can create the IHttpHandler to send the stream, thus avoid some page life circle, increase the performance. Here is the link

C# WebRequest Login Session

Okay I tried asking this question yesterday but i'm not sure if I gave enough info, i got an answer but it hasn't worked for me. Basically what i'm doing is the user opens this windows forms application and logs in. Afterwhich they enter some text into a textbox and click run. At this point the run function is making a webrequest to a server that requires a login (the login that is initially done after they open the program. For some reason its still not seeing that the user is logged in when performing the second request even though the cookies are added too a cookie container. I'm not sure what i'm doing wrong but I will post my code so you can further help me.
This is the function that is performed for the login when the user enters the application.
private void button1_Click(object sender, EventArgs e)
{
string paramaters = "authmethod=on&chkRememberMe=on&login-form-type=pwd&password=" + pw.Text + "&userid=" + uid.Text + "&username=" + uid.Text;
string strResponse;
HttpWebRequest requestLogin = (HttpWebRequest)WebRequest.Create("https://www.url.com/login.form");
requestLogin.Method = "POST";
requestLogin.CookieContainer = cookieJar;
requestLogin.ContentType = "application/x-www-form-urlencoded";
requestLogin.ContentLength = paramaters.Length;
StreamWriter stOut = new StreamWriter(requestLogin.GetRequestStream(), System.Text.Encoding.ASCII);
stOut.Write(paramaters);
stOut.Close();
HttpWebResponse responseLogin = (HttpWebResponse)requestLogin.GetResponse();
StreamReader stIn = new StreamReader(responseLogin.GetResponseStream());
strResponse = stIn.ReadToEnd();
stIn.Close();
//Add cookies to CookieJar (Cookie Container)
foreach (Cookie cookie in responseLogin.Cookies)
{
cookieJar.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), cookie.Path, cookie.Domain));
richTextBox2.Text += cookie.Name.ToString() + Environment.NewLine + cookie.Value.ToString() + Environment.NewLine + cookie.Path.ToString() + Environment.NewLine + cookie.Domain.ToString();
}
if (strResponse.Contains("Log On Successful") || strResponse.Contains("already has a webseal session"))
{
foreach (Control cont in this.Controls)
{
cont.Visible = true;
}
loginPanel.SendToBack();
loginPanel.Visible = false;
}
else
{
MessageBox.Show("Login failed.");
}
}
This is the function that is ran when the user clicks the "run" button to initiate the tests on a consumer account.
private string runTestRequest(Uri url, string parameters)
{
string testResults = string.Empty;
HttpWebRequest runTest = (HttpWebRequest)WebRequest.Create(url);
runTest.CookieContainer = cookieJar;
runTest.Method = "POST";
runTest.ContentType = "application/x-www-form-urlencoded";
StreamWriter stOut = new StreamWriter(runTest.GetRequestStream(), System.Text.Encoding.ASCII);
stOut.Write(parameters);
stOut.Close();
StreamReader stIn = new StreamReader(runTest.GetResponse().GetResponseStream());
testResults = stIn.ReadToEnd();
stIn.Close();
return testResults;
}
And of course this is my cookie container object
public CookieContainer cookieJar = new CookieContainer();
P.S.: The domains of the webrequests are different. First being abc.com 2nd being 123.com The only problem is that the first domain (which is the login) is a global login for internal web applications like 123.com, so how would i use the login session from the 1st domain with the 2nd domain?
Can you please assist in helping me figure out what I am doing wrong.

I found out that what was happening was it was redircting to a subdomain on the same domain as the 2nd (123.com) to use the login. Evidently they had this global login system built on the multiple domains to pass the cookies. The code above DOES work and i do have it working now. Thanks!!

Automate downloads from password protected website [duplicate]

This question already has answers here:
Login to the page with HttpWebRequest
(2 answers)
Closed 6 years ago.
I need some help with a work project I have been assigned. At the moment we manually go to the site, logon and then download 2 excel files from a supplier's website every month. The files are then loaded into SQL.
We want to automate this process. Now the loading of the files into SQL I can do, but I am not sure how I can automate logging onto the website entering my user details and collecting the files. I mostly deal with SQL and have very little .NET experience, so any code samples would be most appreciated.
Just to confirm. The logon form is on a aspx page. just a basic form with a table containing the username & password fields, the forgotten password link and the logon button

You can either use webclient or httpwebrequest.
Login to the page with HttpWebRequest
How do you login to a webpage and retrieve its content in C#?
Httpwebrequest example:
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://sso.bhmobile.ba/sso/login");
req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)";
req.Method = "POST";
req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
req.Headers.Add("Accept-Language: en-us,en;q=0.5");
req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
req.KeepAlive = true;
req.Headers.Add("Keep-Alive: 300");
req.Referer ="http://sso.bhmobile.ba/sso/login";
req.ContentType = "application/x-www-form-urlencoded";
String Username = "username";
String PassWord = "Password";
StreamWriter sw = new StreamWriter(req.GetRequestStream());
sw.Write("application=portal&url=http%3A%2F%2Fwww.bhmobile.ba%2Fportal%2Fredirect%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Ftype%3Dssologin%26url%3D%2Fportal%2Fshow%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Fidc%3D1023278&realm=sso&userid=" + Username + "&password=" + password + "&x=16&y=11");
sw.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
string tmp = reader.ReadToEnd();
foreach (Cookie cook in response.Cookies)
{
tmp += "\n" + cook.Name + ": " + cook.Value;
}
Response.Write(tmp);
Response.End();
Webclient example:
WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential("username", "password");
string url = "http://foo.com";
try
{
using (Stream stream = wc.OpenRead(new Uri(url)))
{
using (StreamReader reader = new StreamReader(stream))
{
return reader.ReadToEnd();
}
}
}
catch (WebException e)
{
//Error handeling
}
