Title: Com Object problems when using webserver app as a service
Post by: MikeR on May 11, 2013, 12:47:52 AM

Hi, clever people,

I have converted one of my webserver apps to a service using self service
When I run the application as a normal exe everything works fine.
When I run it as a service I seem to experience problems with calls to com objects.
I think its some authority issue with windows but don't know where to look.

The symtoms are:
My office inside excel spreadsheet export no longer works.
I can't see any messages in debugview using p_web._trace ..
I think p_web._trace also uses a com object.

Many thanks.

>> I think p_web._trace also uses a com object.

no it doesn't it uses a windows API call.

perhaps you need to change the settings of your service -
Services Manager (services.msc) - right click on the service and go to properties.
I'm thinking that Excel is not installed into the "user" that you have your service running as.

cheers

Thanks Bruce ill check that Monday when im back in the office,
any clue why I cant see the p_web._trace messages when I run debugview on the server ?
I can see it on the server when the app is run as an exe but not when its running as a service ?

I'd have to check, but I don't think debugview messages go from a service to a desktop. Not sure, I've never tried.

cheers
