I am looking to do some work using Outlook.  This is a link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnout98/html/ms
dn_movs105.asp
that explains what I am going to do.

My question is how do I find documentation for Interop Modules

Given the following code, how can I find out what the parameters of Logon( ) are and
if the method throws exceptions, etc.  

    Dim oApp As Outlook.Application = New Outlook.Application

    ' Get NameSpace and Logon.
    Dim oNS As Outlook.NameSpace = oApp.GetNamespace("mapi")
    oNS.Logon(Missing.Value, Missing.Value, False, True) ' TODO:

    ' Get Appointments collection from the Calendar folder.
    Dim oCalendar As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar)
    Dim oItems As Outlook.Items = oCalendar.Items

I specifically am looking for the Outlook information at the present time but would like to find
ANY Interop documentation in the future.  Using F1 on the key word doesn't go anywhere and
trying VS search or google returns so many pages that it like looking for a needle in a hay stack.

Any help is appreciated.

Cheers,
Dave
