Problem: Windows Service creating Outllook object

W Akthar

Hi

I am trying to create a windows service which queries SQL
Server on timed intervals and depending on the results
send appointments to Outlook.

The problem lies when I try to create an outlook
application object.


StreamWriter sWriter6 = new StreamWriter
(@"C:\CMSOutlook.log", true);
sWriter6.WriteLine(" ** Doing Outlook Stuff **");
sWriter6.Close();

// Add it OUTLOOK
Microsoft.Office.Interop.Outlook.Application oApp = new
Microsoft.Office.Interop.Outlook.Application();

StreamWriter sWriter10 = new StreamWriter
(@"C:\CMSOutlook.log", true);
sWriter10.WriteLine(" ** Getting Namespace **");
sWriter10.Close();

Microsoft.Office.Interop.Outlook.NameSpace oNS =
oApp.GetNamespace("mapi");

StreamWriter sWriter11 = new StreamWriter
(@"C:\CMSOutlook.log", true);
sWriter11.WriteLine(" ** Setting Profile **");
sWriter11.Close();


I have a try catch block around this but it never goes
into the catch block.

The log file has the following

** DO DATABASE **
** Connecting **
** Connected OK **
** Closing Connection **
** Closed OK **
** Count = 5 **
** Doing Outlook Stuff **

** DO DATABASE **
** Connecting **
** Connected OK **
** Closing Connection **
** Closed OK **
** Count = 5 **
** Doing Outlook Stuff **

** DO DATABASE **
** Connecting **
** Connected OK **
** Closing Connection **
** Closed OK **
** Count = 5 **
** Doing Outlook Stuff **


Does anyone have any ideaq why this is happening ?????
PLEASE HELP !!!!!!!!

W Akthar,

What do you have in your try/catch block? It's hard to tell without
seeing that, but it would seem that you are not writing to the log in it.

Hope this helps.

The problem is that "Outlook" (or any other Office application) is not
built to be automated from "Windows Services".
Don't know which identity is used to run your service, but try with
"LocalSystem" and set "Interact with Desktop" and watch the nice dialog box
wich remains invisible when you run under another identity.

Willy.
