C# + Outlook addin + Context menu functionalities

Hi

I need to implement all the functionalites provided in the context
menu in outlook inbox, in an outlook addin. I am listing all the mail
items in a listview in a form created in c#. Can implement
functionalties like reply, delete, forward by using the following code

//Sample for forward
//oOlMailItem - Collection of Mailitems
oOlMailItem =(Microsoft.Office.Interop.Outlook.MailItem)
oOlMailItems[intI];
object OMissing = System.Reflection.Missing.Value ;
oOlMailItem.Forward().Display(OMissing);

But how to implement these functionalties??
Followup, Find All, Junk EMail, Create rule, Options

Thanks
