How do I get the line number of the sales order and how do I save info?

Question

I am trying to create a form that is able to be called from a right click on the sales order matrix and will display some of the user defined fields associated with the line.
I've managed to create a form and add a menu option to the right click but I'm now stuck because of the following:
1. How to I know which line the user selected? I need the REAL Line Number from the RDR1 table because I need to use it on the data filter of the form.
2. I hard coded a line to just to see if I can load a form and it appears to load and bind the data to the controls, but how do I save changes made? There are several text fields, combo boxes, and a picture control.

Hi Coleman,
1. The pVal returned form a menu event does no provide the LineId, but a pVal from a Item Event does. I suggest you use a DoubleClick or Control + Click on the Line to trigger an event that you can catch and use to launch your form.
2. Please note that if the Sales Order line is closed you'll not be able to update the values. If it's not, then you need to instantiate a Sales Order document, get the correct document with the GetByKey method and update whatever fields you need.
                Dim oSalesOrder As SAPbobsCOM.Documents = oCompany.GetBusinessObject(BoObjectTypes.oOrders)
                If oSalesOrder.GetByKey(docentry) = True Then
                    oSalesOrder.Lines.SetCurrentLine(pVal.Row - 1)
                    oSalesOrder.Lines.UserFields.Fields.Item("U_MyUDF").Value = ""
                    oSalesOrder.Update()
                End If
