Hello All,

The following error occuring while creating a process instance,

here is my code:

private

string strK2Server = ConfigurationManager.AppSettings["PlanServer"].ToString();

private string strProcessName = System.Configuration.ConfigurationManager.AppSettings["ProjectName"] + Practise;

 

Here "Practise" is my K2 process name 

protected

void Button1_Click(object sender, EventArgs e)

{

Connection oK2Connection = new Connection();

oK2Connection.Open(strK2Server,

"[;];Authenication=Windows;Domain=scsdomhyd01.in;User=kishorek;Password=kishore001");

ProcessInstance oProcInst = oK2Connection.CreateProcessInstance(strProcessName);

oProcInst.Folio = "Manager Approval";

oProcInst.DataFields["Full Name"].Value = TextBox1.Text;

oProcInst.DataFields["Email"].Value = TextBox2.Text;

oProcInst.DataFields["Destination"].Value = DropDownList1.SelectedItem.Value;

oK2Connection.StartProcessInstance(oProcInst);

}

please give me the solution for this.

 

Thankyou
