Application.ActiveExplorer().Selection fails in C# applica..

Hi Ken,

Thanks for your reply. I tried to do as you suggest right now - however, the
app.Explorers property also throws the same exception, so I can't count them
or access the array in the way you suggest.

It seems like Outlook hates my application, I just can't understand why I
can subscribe to events, yet not be able to read basic information like this
from the Application object.

(Btw, if I subscribe to events, they work - in my example subscribing to
NewMailEx and recieving a new mail, I actually do get the event with the ID)

Any other ideas? I'm scratching my head...!

Thanks again!

Rune

Definitely something I've never seen or heard of. Congratulations

If you use your application object and put a dot after it does intellisense
show the objects that are exposed under Application such as Explorers and
Inspectors, etc. ?

You are referencing the correct version of Office as installed on your dev
machine and it's the earliest version of Office you want to support? Are the
PIA's for that version of Office installed?

Ken,

Thanks, I feel honored!

I am guessing this should "just work" then, since both Outlook 2007 and my
app is running as the same user? No need to do any fancy login or anything
like that, just create a new Application object?

Intellisense kicks in on my Application object, so it is definately
recognizing the object type.

All my users will be on Outlook 2007 and Vista (Same as me), so that should
hopefully save me some hassle (once I get it to work).

I should note that I am currently referencing Microsoft.Office.Core /
Microsoft.Office.Interop.Outlook through the Microsoft Office 12.0 Object
Library - found in the COM tab of the Add Reference dialog box, and the dll
files referenced are in the GAC. I have also tried to do this with the
Microsoft.Office.Interop.Outlook (v12.0.0.0) found in the .NET tab and
installed as \Microsoft Visual Studio 9.0\Visual Studio Tools for
Office\PIA\Office12\Microsoft.Office.Interop.Outlook.dll - with exactly the
same result.

I will try to make a new project that does only this from scratch - a C#
console app, to keep it simple - and report back if that makes a difference.
However, if you have any further suggestions, I would really appreciate it;
If the weekend comes without me figuring this out, I suspect my boss will
find a pretty blunt object to beat me with.

Thanks very much for helping out so far!

Rune

Hi again,

Just a quick followup with the test project I created. I referenced the COM
Interop library (which automatically included both Microsoft.Office.Core and
Microsoft.Office.Interop.Outlook for me), and my console app consists of this
single class (probably messed up formatting wise):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Microsoft.Office.Interop.Outlook;

namespace OutlookTest
{
class Program
{
static void Main(string[] args)
{
var app = new Application();
Console.WriteLine("{0} selected",
app.ActiveExplorer().Selection.Count);
}
}
}

The app object is created, and it throws the exception on the WriteLine. If
I check the app object with the debugger, I see that almost every property
causes the same exception as I get in my real application.

I really don't have a clue what to do to get it to behave, so any tips would
be highly appreciated!

Thanks!

Rune

Try fully qualifying the reference and making the objects class level, plus
since it's an external app set up NameSpace. See if this works:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Outlook = Microsoft.Office.Interop.Outlook;

namespace OutlookTest
{
private Outlook.Application _app = null;
private Outlook.NameSpace _ns = null;

class Program
{
static void Main(string[] args)
{
_app = new Outlook.Application;
_ns = _app.GetNameSpace("MAPI");
_ns.Logon("", "", false, false);

Console.WriteLine("{0} selected",
app.ActiveExplorer().Selection.Count.ToString());
}
}
}

Ken,

Thanks for following up!

I tried to do as you suggested, and reduce this to the simplest possible C#
console application. Here is the complete source code for my mega advanced
application:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Outlook = Microsoft.Office.Interop.Outlook;

namespace OutlookTest
{
class Program
{
private static Outlook.Application app = null;
private static Outlook.NameSpace ns = null;

static void Main(string[] args)
{
app = new Outlook.Application();
ns = app.GetNamespace("MAPI");
ns.Logon("", "", false, false);

Console.WriteLine("{0} selected",
app.ActiveExplorer().Selection.Count);
}
}
}

However, on the Console.WriteLine line I still get the
System.AccessViolationException. It also says something about reading/writing
to/from corrupted memory - not sure about the exact English wording as I get
the error message already translated to my native norwegian.

So, this is strange, right? Shouldn't this just work?

Thanks again!
