Hello World (C++) - SDK sample

Hello World sample is a simple Windows console application that prints one page with the "Hello World" text to the novaPDF Printer. It demonstrates the basic use of the INovaPDFOptions interface. The printing job is made with Windows API calls OpenPrinter, StartDoc,… It generates a "Hello World.pdf" file in the working folder.

Note: To be able to use the samples you must install novaPDF SDK as samples work only with it. Download it here: novaPDF SDK.
Notice If you do not use Windows API calls to print to novaPDF Printer, but you perform a print job by calling other controls "Print()" method, or if you print an existing document using "ShellExecute()" function, you should check the MFC Converter sample instead.
