C# Integration using editissue to update Project parameters list

The following code fixed my issue thank you Nolin Borrero Jr.. per his email

*********************************

I(Nolin Borrero Jr) believe the error is telling you it cancelled because you
didn't give it enough info. For some reason you need to specify host and port
twice. Once for the IIntegrationPoint and once in the Command. Here's a sample
from my code:
Command cmd = new Command("im", "viewissue");
cmd.AddOption("hostname", hostServer);
cmd.AddOption("port", hostPort.ToString());
cmd.AddOption("user", userName);
cmd.AddOption("password", userPassword);
cmd.AddOption("substituteParams");
cmd.AddSelection(IssueID.ToString());

APIFactory.MKSInitialize();

IIntegrationPoint ip = APIFactory.CreateIntegrationPoint(hostServer, hostPort,
false, 4, 13);

Let me know if this helps or not.

Also, as an fyi, take a look at the Integrations Builders Guid and look for the
section "Accessing Item Fields" for info on how to parse the
response. I have a lot of bad code written that I'm going to have to go back
and fix because I didn't read this section.

WORKING CODE SNIPET

APIFactory.MKSInitialize();

ip = APIFactory.CreateIntegrationPoint("mks.corp.knorr-bremse.com", 7001, false, 4, 13);

session = ip.CreateSession(<user name>,<password>);

Command issuesView;

issuesView = new Command(Command.IM, "editissue");

issuesView.AddOption("field", "parameter values=a_16_Auto_FV_Minus_20_psi=64");
issuesView.AddOption("hostname", hostName);
issuesView.AddOption("port", port.ToString());
issuesView.AddOption("user", userName);
issuesView.AddOption("password", password);

issuesView.AddSelection("478424");

r = session.RunCommand(issuesView);
