Synergy CSP Substream Initialization

The sample code for starting the substream can be found below. Note:

• From the project named TEST, Flow1 of the project named TEST2 is started as a substream.
• The TextBox object in the form that will come in front of the user in the starting subflow is assigned a value from the main flow.
• With an assignment object in the starting subflow, the position object after the subflow starts is selected from the variable to which user the process will go. The value to be assigned to this variable is also sent to the substream in the following codes.

Used to access the document of the substream
            var form = process. Documents["Document1"]. FormInstance;
            form. Controls["TextBox1"]. Value = "substream";
            form. Save();
            Causes the subflow to be initiated with the send event
            process. StartingEvent = process. Events[4];
            The processId of the main flow from which we started the subflow is sent
            MainProcessId is the name of the public variable we defined in the substream
            process. Variables["MainProcessId"] = _workflowData.General.ProcessId;
            In the subflow, the userId of the user we want to approve is sent
            VarUserId is the name of the public variable we defined in the substream
            process. Variables["VarUserId"] = "2";//stream will fall on the ndale user

return process. SaveAndContinue();
        }
