Inside my DLL- get list of printers

I'm using Visual Studio 2015. I have a Visual Basic DLL.
Inside the DLL, I'm trying to get a list of printers.
I get an "Unspecified error " on


strComputer = "."

objWMIService = GetObject("winmgmts:\\ & strComputer & "\root\cimv2")


the "GetObject" is where I get the error.

Overview- I have a web page. I want the user to push a button. It calls
my DLL that is on the server and it submits a document to the print job.
The printing is done on the server, NOT the client printer.



Suggestions ?

TIA

Is this for ASP.NET or for a Windows Form Application?

This is for ASP.NET

My first guess would be permissions, I am not sure if the default account IIS uses to run applications has permissions to WMI.

IIRC IIS defaults to "Network Service" as the user. You could either grant permissions to this account or it might be more preferable to create a new user account to run your application under and make sure this account has access to WMI.

Thread moved to the ASP.Net forum.

You all do realize that with this being asp.net, anything you do printer wise will run on the IIS Webserver so you'll need to have a printers(s) connected to it (not the end user who's browsing the website) which is extremely rare in the first place and besides that, what would you even want to have printed directly from your web server(s) anyways?
