How do you convert a doc file into a pdf file using C sharp code?

Answer 1

Originally, a full version of Adobe's Acrobat application was required to create PDF (Portal Document Format) files from any application, including Microsoft Word. Subsequently, a number of companies sold inexpensive PDF conversion software to compete with the more expensive Adobe product. These applications, like Acrobat, used a printer driver to "print" Postscript-based PDF files. The Mac OS central window server caches window graphics in PDF, allowing any Macintosh application to print to a PDF file from within the OS.

Today, all current versions of Microsoft Word will save directly into PDF format. There's no need to use Visual Basic, assuming you have Microsoft Word.

You can create PDF files programmatically in VB6. You'll need the mjwPDF class and the appropriate PDF fonts. A tutorial on the subject has been attached to this page as a related link: Tutorial - Create PDF files with VB6

Inaddition, you also can use enolsoft PDF Creator to do that. It's fast and simple yet.

There are a number of third party assemblies available online that will do the job. You can also take adavantage of the add-in in Word 2007 that saves the DOC file as PDF. All you need to do is to use the word objects to access this functionality through C#.
