Send Invitations
         


        

Answer 1

Well a button with no id or name like that will submit whatever form it is contained within - if you know the HTML, then does the form have an id? If so you can find the form by it's id and call it's submit method.

In fact you would probably be better to find out all the fields of that form and then just POST to it yourself:

var inputs = new NameValueCollection();
inputs.Add("field1", "value1");
inputs.Add("field2", "value2");
inputs.Add("field3", "value3");

System.Net.WebClient Client = new WebClient();
Client.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
byte[] POSTResultData = Client.UploadValues(postUrl, inputs);
