Hi,

My goal is to create a whole raft of New requests based on the data held in our old workflow system. So I will want to loo through my old requests and for each one raise a new WFGen request and populate some of the data.

If I use a link in a web browser I can successfully create a blank new request. What I really need is to pass it a context as well so fields will be populated and do this from c# code within a for each loop.

My issue appears to be finding the right credentials to use. If I use my windows logon and password I get an authentication message. That surprised me because when I use the url without any credentials it must surely be using windows authentication.

The code I have used is pretty much a copy of the code in the Documentation with a couple of minor changes to allow it to be run from a windows form rather than a web procedure.

Here is a snippet of what I am trying

```
       ContextParameters myCPs = new ContextParameters();
        ContextParameter myParam = new ContextParameter();
        myParam.Name = "SELLECT_EMPLOYEE_TXTEMPLOYEENAME";
        myParam.Value = "Simon Breeze";
        myParam.Direction = ContextParameter.Directions.In;
        myCPs.Add(myParam);
        myCPs.Update();
        string myContext = myCPs.GetXml();

        string apURL = Url + "&L=" + Language + "&ProcessName=" + ProcessName
            + "&RequesterName=simon.breeze&Test=" + Test;
        System.Net.NetworkCredential mycred = new System.Net.NetworkCredential
                (UserName, Password, UserDomain);
        System.Net.CredentialCache myCache = new System.Net.CredentialCache();
        myCache.Add(new Uri(Url),"Basic",mycred);

        //Prepare request
        System.Net.HttpWebRequest httpWebReq = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(apURL);
        httpWebReq.Method = "Post";

        //Set Authentication
        httpWebReq.Credentials = myCache;

        //Set Context info
        string postData = "CONTEXT=" + WebUtility.UrlEncode(myContext);
        System.Text.ASCIIEncoding encoding = new ASCIIEncoding();
        Byte[] Buffer = encoding.GetBytes(postData);

        //Set the contenttype of the data being posted
        httpWebReq.ContentType = "application/x-www-form-urlencoded";
        httpWebReq.ContentLength = postData.Length;

        //Send the context
        System.IO.Stream myStream = httpWebReq.GetRequestStream();
        myStream.Write(Buffer, 0, Buffer.Length);
        myStream.Close();
        HttpWebResponse httpWebResp = null ;

        try
        {
             httpWebResp = (System.Net.HttpWebResponse)httpWebReq.GetResponse();
        }
        catch(WebException ex)
        {
            MessageBox.Show(ex.ToString());
        }

```

Thanks

Simon

Hi @simon.breeze,

Please refer to this article if you would like to launch a new request via URL with context parameters:

>
> This procedure lets you launch a new process from another application using SDK-style parameters. Notes The process to be launched must be a public access level sub-process. This solution is not available with WorkflowGen Standard and StandardOne licenses in version 5. URL Use the URL http://[myserver]/wfgen/show.aspx?QUERY=PROCESS\_START\_REMOTE, replacing [myserver] with the name of your server. Required parameters PROCESS Type: String Description: Name of process to launch TEST…
