Hello World VB |

|
Hello World VB sample is a simple Windows console application that prints one page with the "novaPDF says Hello World from VB" text to the novaPDF Printer. It demonstrates the basic use of the INovaPDFOptions interface. The printing job is made with calls to the global Printer object defined by VB. It generates a "HelloWorld.pdf" file and opens it in the default PDF viewer.
Notice If you print an existing document using "ShellExecute()" function or you want to handle printing events, you should check the VB Converter sample instead.
