Have you tried passing the COMAddIn object from the jscript to the
UserControl (i.e. add another parameter to the Initialize method that
accepts the object)? Just a thought, you'll probably hit the same barrier
you're hitting now but maybe you'll get a useful exception. Also, at this
point
addins = olapp.COMAddIns
can you get a value for addins.Count? If not does it throw an exception? If
it does, can you iterate through the collection?

Thanks for the reply Dave.

I have tried the moral equivalent of the jscript in .NET, but it seems to
come down the following problems:

- When I get back the AddIns collection from within .NET, i.e. with this:

Dim o As Microsoft.Office.Core.COMAddIn
Dim addins As Microsoft.Office.Core.COMAddIns
addins = olapp.COMAddIns
o = addins.Item("TheRightProgId")

..then the COMAddIn.Item.Object is alway 'null'.

- I know that I can access the object because the jscript (the one that
actually launchs the .NET UserControl) works fine, i.e. can use the
COMAddIn
.Object just fine.

Also, to be clear, I need info/funcitonality from my AddIn, not just
general
Outlook info.

More Background, in case it's useful:

- This is a .NET 1.1 Shimmed Outlook Add-in written in C#
- Using Outlook 2003 (although I need it to work for more than just 2003,
which is why I didn't go the VSTO2005 route).
- If I write a stand-alone VB.NET app that get's a new _app, i.e. outside
the AddIn Outlook.ApplicationClass, then the COMAddIn.Object are always
'null' too, even though they 'run' and are shown '.Connected=true'

Any help, ideas etc most appreciated...

I haven't tried this but I assume that you already tried the equivalent
of
your in-page jscript and that didn't work. You can get to an add-in in
the
running Outlook session from IE hosted in a FHP, but a standalone browser
has different security barriers. Perhaps your UserControl, even though
it's
hosted in the FHP, is hitting those barriers. Do you need to reach the
add-in instance that Outlook loaded on startup, or just access Outlook
data?

Hello,

I have a .NET winforms UserControl hosted inside a HTML page which is
referenced as a Outlook Folder Home Page. (Kind of like the recent MSFT
CRM
Integration example)

The .NET UserControl is initialized by using the following bit of
jscript
in
the HTML:

var oApp = window.external.OutlookApplication;
SomeControl.Initialize(oApp);

So what I need some info around is this: How do I, from my .NET
UserControl,
gain access back into my .NET Outlook Add-in instance?

Paraphrased, I need to be able to call .NET functions from my
UserControl
(the one hosted in the HTML page) back into the Outlook-Addin.

In jscript, in the same HTML page, I can reference the Add-In using the
COMAddIns enumeration, i.e (roughly):

var addin = app.COMAddIns.Item("MyAddIn.Connect");
var h = addin.Object;
h.AdotNetFunctionInMyAddIn("hello")

But how would I do this from within my .NET UserControl in C#?

Any help, clues, ideas appreciated. Thanks!
David
