DeletePrinterConnection

Hi

I'm a bit stuck with VS 2010 C++ when it comes to deleting a printer.

This works:

String^ printer = "something";

AddPrinterConnection(printer);

However, if I follow this with, say:

DeletePrinterConnection(printer);

I get "error C3861: 'DeletePrinterConnection': identifier not found".

I'm unclear as to why I can't delete a printer this way. I've looked on:

and I'd have thought all was fine with this method. Can anyone help me please?
