OLE and NT Service

Hi
I have written an console application that requires the use of MAPI and OLE. After testing my program, I feel that instead of a console application, I should have changed it to a NT service instead. So I got the code CNTService.cpp, .h and relevant files and start to change my original program. Now I am stuck as OLE does not work as desired. I know that there is nothing wrong with my code, as a console application, its working. My question is, is there any speical considerations when using OLE and even MAPI in a NT Service. If yes, what are the things to note.

You aren't alone with this problem. I'm trying to use ODBC from within an NT Service and have run into the same problem. My program works fine as a console but fails as a service. I suspect it has something to do with the initialization of the OLE libraries from within a service. AfxWinInit() might play a role here but I don't know. Just have to keep sifting through the **** Microsoft calls documentation.


Freedom is knowing you can burn all your software without losing a minute's sleep.

In case anyone comes across this post while searching (as I did), this might be useful. You may find that you have to explicitly initialise COM security when running as a service, but not when running as an application. The following code may help:

Code:

---

CoInitializeSecurity(NULL, -1, NULL, NULL, RPC_C_AUTHN_LEVEL_DEFAULT,
                    RPC_C_IMP_LEVEL_IDENTIFY, NULL, 0, NULL);
