I program in visual basic.net and want to convert an HTML file to a PDF file. I can do that with a 3rd party program, but I want my vb.net application to do it. Does anyone know where I can get a component or whatever to do that. I do not want to pay for it. Thanks.  

Hi Phil.
Its quite a tricky thing to do, which is why people charge money for software to do it.

There are sites that will do the conversion for you, on a once off basis like:
http://www.htm2pdf.co.uk/

What you can do is make a web service that accepts your html, sends it to this site and returns the pdf file. I wrote a translator tool a while back, that posted your text into babelfish and returned the translation, by reading the page html. you can do it the same way.

Otherwise, there are quite a few paid tools that will do the trick.
Try these guys: Tall Components

I think they have a free trial, or at least a beta that might work

See if that helps
