You cannot create ActiveX controls using .NET. An ActiveX control is a
compiled COM application that downloads to the user's client browser and
attempts to execute there. There is no such equivelent in .NET.

There is no way to open Outlook directly from the HTML of a web page, nor
from the C# "code behind" which is executed on the server running IIS.
If, however, you are programming for your own intranet, or can guarantee
that the user is running IE and will execute code from your site with
enough privelege, you can write an embedded activeX control and call it
from javascript within your page. Because the ActiveX control will
download to the client and run there, you can do more or less anything you
could do in a normal user program.
Of course, if you write the ActiveX control in C#, you're dependent on the
correct version of .NET already being installed on the client machine,
too.
Oh yes there is. I've written them.

No, you haven't. You can write .NET components that expose themselves to
COM via InterOp. But, the .NET Framework does not emit native ActiveX
components (which are COM objects).

Oh, for heaven's sake... The difference (in this context) is ?
The difference is that you are telling the OP that you can do something that
you can't.
If you don't even know what technology you are using, how can you be of
help? Your advice is just going to confuse matters for someone who
obviously is new to .NET development.

Hi Everybody
Access 2000, Outlook 2000 Windows XP
I am running the code below to open Microsoft Outlook from a Command
Button. It works fine until I tried it on a machine that has Office
installed on something other than the "C" drive.
So can anyone advise me how to open Outlook by using a relative path
rather than the code I am using here.

I have an Outlook add-in solution which includes a setup project. If I

I use the setup generated in the setup project Release folder then even
though setup runs and finishes, the Outlook Add-in does not appear in
Outlook. What is the problem and how can I fix it?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
