Hi All
Using IIS 6.0 - Windows 2003 Server
ASP.Net 2.0 Framework
C#
Using Impersonation with Network Administrator username/Password
I am attempting to print an Adobe PDF document from a web page
using the code listed at the bottom of this message.
When I press the button to print I get the following output
Both the Adobe Exe and the PDF documents have been copied to the
Namespace on the IIS server.
Tried using @"C:\Program Files\Adobe\Acrobat 7.0\Reader\AcroRd32.exe";
but that does not work either
First am I logged in as the Administrator on the IIS server and
therfore should have the same permissions as the network
adimistrator !!!
Secondly, if not how can I tell who I am logged on as ?
From what I have read I think that the code should work but I cannotwork out why it will not do thge job
Any assistance offered will be greatfully accepted
Best regards
Iain
