Controlling robot IO with Robot Web Services

gbdalar

Hi

I am trying to get my head around using Robot Web Services. I have created a c# client application which can read a robot signal, this all seems to be fine, but I am now trying to understand how to set the signal from the application. There does not seem to be any examples on how this is done in c# in the documentation, I have done it using a html page but can not seem to work out how it is done in c#. Any one who could send me an c# example of how this is done would be great and very much appreciated.

Hi

This method works fine for me

HttpWebResponse ChangeIoSignalValue(string url, string prevvalue)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url + "?action=set"));
    request.Credentials = _credentials;
    request.Proxy = null;
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    request.CookieContainer = _cookies;

    string body = null;
    if (prevvalue == "1")
    {
        body = "lvalue=0";
    }
    else
    {
        body = "lvalue=1";
    }

    // write to the http stream object
    Stream s = request.GetRequestStream();
    s.Write(Encoding.UTF8.GetBytes(body), 0, body.Length);
    s.Close();

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    return response;
}

using (HttpWebResponse response = ChangeIoSignalValue(signalUrl, oldIOValue))
{

}
