Error: failed due to the following error: 80040154 when i call Req() class

Question

I use OTAClient.dll from HP for conencting with Quality Center. My connection is correct:

TDConnection tdCon = new TDConnection();
tdCon.InitConnectionEx("http://....");
tdCon.Login("username", "userpass");
tdCon.Connect("****", "********");

But in this area i get error:

Req newReq = new Req();

I set platform target in x86 but didn't help me

Answer 1

Instead of COM object use the rest library. You could send xml documents with parameters for creating and updating requirements(Req) in QC. You can find documentation in QC. You will use "post" method by HttpWebRequest for creating and updating, "get" method for getting session parameters. In the rest library look to creating entity description. For maintaining connections you must save QCSessionId. Look to authentication description. Good luck!
