Couldn’t open PDF. Something’s keeping this PDF from opening. With VB.NET PrintForm

Question

I am trying to print Form using PrintForm in VB.Net

This Form has few labels and a chart control. I have used this very simple code

 Dim pf As New PrintForm
    pf.Form = Me
    pf.PrintAction = PrintAction.PrintToFile
    pf.PrintFileName = "../../generated_pdf.pdf"
    pf.Print()

It generated "generated_pdf.pdf" file. When I am trying to open this file it gives me an error Couldn’t open PDF Something’s keeping this PDF from opening.

Any ideas on how to resolve this error and successfully generate a working pdf that can be opened and viewed with it's right contents?

The form that should be converted to pdf looks like this

Answer 1

PrintForm does not know how to handle PDF files, which is why its not working.

It only knows how to do .eps, .ps & .ai.

If you want PDF, you'll need something that knows how to turn one of the above formats into a PDF.

Ghostscript & Ghostscript.Net do this nicely and are free & open source. There are others, but I've actually used these and know they work.
