ASP.NET PDF generator - SDK sample

Hello World (ASP.NET PDF generator) sample is a simple ASP application that generates one PDF file containing the text "novaPDF says Hello World from ASP.NET". The PDF is created using the novaPDF printer driver and is saved in the “upload” folder. It demonstrates the basic use of the INovaPDFOptions interface. The printing job is done using the package System.Drawing.Printing

Note: To be able to use the samples you must install novaPDF SDK as samples work only with it. Download it here: novaPDF SDK.

What this sample does:

  • determines the active profile, makes a copy of it and names it "Test ASP.NET"
  • sets the new profile (Test ASP.NET) as active as well as some mandatory settings
  • generates a test PDF file and saves it in the “upload” folder
  • restores the original settings of the novaPDF printer driver.

To test this sample on IIS, you should set the Application Pool to run under the “Local System” Account. Here’s how you can do this:

  • In IIS Manager, expand Local computer, the Application Pools folder, right-click the application pool you would like to configure (the one selected for this application/ virtual directory) and click Properties.
  • Go to the Identity tab.
  • Click on Predefined and in the list box beside it click Local System.
  • Click OK.
