WebClient Problem

[Max Gattringer]

Hi,

I've got a little problem with the WebClient, I always get a failure while
debugging this code:

private void menuItem2_Click (object sender, System.EventArg s e)

{

NameValueCollec tion values = new NameValueCollec tion();

values.Add("ppt pdisconnect","t rue");

string got =
UploadValuesToS ecureWebsite("h ttp://192.168.0.1/","admin","**** ***","post",v
alues);

}

public string UploadValuesToS ecureWebsite(st ring URL, string Username,
string Password, string Method, NameValueCollec tion values)

{

WebClient myWebClient = new WebClient();

NetworkCredenti al trust = new NetworkCredenti al(Username,Pas sword);

myWebClient.Cre dentials = trust;

byte[] Response = myWebClient.Upl oadValues(URL, Method, values);

string result = Encoding.ASCII. GetString(Respo nse);

return result;

}

Regards, Max - I hope my English was understandable, or even good ;-)
PS: Here, the details about the failure:

at System.Net.Conn ectStream.Begin Read(Byte[] buffer, Int32 offset, Int32
size, AsyncCallback callback, Object state)
at System.Net.Conn ectStream.Read( Byte[] buffer, Int32 offset, Int32 size)
at System.Net.WebC lient.ResponseA sBytes(WebRespo nse response)
at System.Net.WebC lient.UploadVal ues(String address, String method,
NameValueCollec tion data)

I've worked A LOT with the web client, in fact, have a whole web site
scraping/auto form login/message board setup now.

It appears that the error you are getting is probably caused by the site
disconnecting you as the error is occuring in the 'response' section of the
connect methods.

I don’t know exactly, however, I am going to take a wild guess here.. Are
you sure that the "pptpdisconnect " variable is supposed to be True and not
"on" or blank? And is the server killing the connection because it is seeing
bad data coming across. Seeing that this is a "post" operation, most posted
webpages, using checkboxes, indicate the true, or checked state, with "on"
and not "true".

Try that and see. Also, it would help to know the exact exception that you
were getting... I know I probably have the book of every one you can
possibly get after writing this thing. Break the program when the exception
occurs, print the e.message, as well as the e.innerexceptio n.message if the
innerexception is set.

Hi, just found my failure: All my methods completely okay, but i always
used http://192.168.0.1, but actually i had to use
192.168.0.1/status.cqi! Shame on me, but at least it works now..
Furthermore there is difference between using
?pptpdisconnect =true/disconnect or whatsover - any value...

Regards, Max
