Hi all!

I'm facing once again a new problem with my VSTO development :( I need to
access the Application.Session object from a window, and I'm unable to,
because my Globals.<nameofmyaddin> is refusing to return anything other than
null :( In the main addIn class, this very same line of code would work, but
here it does not. The line is:

Outlook.MAPIFolder root =
Utility.Folder.GetRootFolder(Globals.GRAAddIn.Application.Session);

This very same line did work in MyAddin.cs class, but does not work from
a Windows Form class.. any tip? I am really in an urge :(

Thanks to all!
Pablo

I don't know if this is the best way but this code can be used for excel
using MSExcel = Microsoft.Office.Interop.Excel;

private MSExcel.Worksheet Sheet;

private MSExcel.Application App;

private void Prepare()

{

App = (MSExcel.Application)Marshal.GetActiveObject("Excel.Application");

Sheet = (MSExcel.Worksheet)App.ActiveWorkbook.ActiveSheet;

}

Thanks for the replay Torben.. I'll look at this approach, at this Marshal
thing :)

Cheers!

You could set up a public object or method in the form and pass the Session
object (NameSpace) to it when you create the form.

Yep, I am able to do that as a walkaround, but I'd love to understand what
is happening, why am I abnle to access from other places and not from a
form. I have little COM knowledge, but I thought it could be because of
accessing the COM object from a form. Makes sense?

Thanks a lot!

I'm not sure, I don't know enough of the plumbing under the hood in VSTO or
the Interop to really be sure. In VB.NET you can set up global Application
and NameSpace objects and reference them from anywhere in your code,
including form code but of course C# has different scope rules and nothing
like true globals as VB.NET does.
