Open Outlook on user machine

[andyoye]

How can I launch Outlook on users machines when they click a button on a web
form (InfoPath)?

Thanks

[Scott M.]

You can't.

Only client-side code can ask the client to do something. Now, you can
certainly have client code that "asks" the browser to open its default mail
client, and that *might* be Outlook, but again, it might not be.

And, for security reasons, JavaScript (the client code we're talking about)
has no abilities when it comes to the OS.

I do not know why do you want to open outlook, however from
application programming side, the normal requirement is to mail
something to someone... In which case System.Web.Mail will help.

Add, from Office (Setup/Add/Repair) ".Net Programmability Support" (not as
load on request, but unconditionally ).

Add the reference to Office Interop to your project and the line

using Outlook=Microso ft.Office.Inter op.Outlook;

(note that this alias may help to remove ambiguity about Application and
Outlook.Applica tion)

and, to clean up, the code is missing a lot. Try adding:

objOutlk.Quit() ;
objOutlk= null;
GC.Collect();
GC.WaitForPendi ngFinalizers();
GC.Collect();
GC.WaitForPendi ngFinalizers();

I do want to open outlook, thats the MAIN objective here.

I ran below code:

Outlook.Applica tion outlookApp = new Outlook.Applica tion();

Outlook.MailIte m message =

(Outlook.MailIt em)outlookApp.C reateItem(Outlo ok.OlItemType.o lMailItem);

message.Subject = "Hello World";

message.Recipie nts.Add(A@aol.c om);

message.Body = "Hello. This is a test.";

I get below error when i try to run it.

You're missing the point. The code you show below will only work if it is
*running* on a machine with Outlook installed. Since you said "web form",
then this could will be running on a web server and there are two issues
with that:

1. Most web servers don't have Outlook installed on them, nor would you want
to as it poses a security risk.
2. Even if the server had Outlook (or the Outlook Primary InterOp Assembly -
PIA), this code runs on the server and won't do anything for the client.

Yes it is a web form, but can the code launch Outlook on a user machine?

Michael,

There are a couple of things wrong with this:

1. The OP asked about opening Outlook on the client but from Web Form code,
which can't be done.
2. Your clean up code is not correct.
a. When calling a COM object via COM InterOp, you must call the
Marshall class's ReleaseComObjec t method, which tells the CLR to release it
connection to the underlying COM object. Since COM objects are freed from
memory when their reference count goes to zero, this step is critical
otherwise the object will persist in memory even though the .NET program
that called it no longer has any reference to it.
b. You really should not ever need to call GC anything except for under
very special circumstances. The GC runs in a separate thread from your .NET
application and the moment you call GC from your application, you force it
to operate in the same thread as your main application. This can actually
result in your application's performance degrading. The bottom line is that
the GC works quite well all on its own and you really shouldn't interfere
with its normal operations because you will most likely not improve matters.

The correct way to "clean up" a COM object from .NET is this:

objOutlook.Quit ();
System.Marshall .ReleaseComObjc t(objOutlook);
objOutlook = null;

Ok for point one, but about point 2, Andrew Whitechapel mentions that
ReleaseComObjec t is scoped to the AppDomain and using it, you risk causing
damage to other applications in the same AppDomain since the RCW is no
longer usable by any of the managed clients in the AppDomain. Furthermore,
you should loop until it returns 0, since sometimes, it may not return 0.
That is why he proposes the sequence I reproduced and conclude that "the
best practice guideline is to not use ReleaseComObjec t" (page 45, "Best
Practices")
