PDF Viewer for Vb.net

Question

User-1767698477 posted

I came across this. I could not get it to work when I opened the solution. Has anyone worked with this before? This is a viewer that works even if Adobe is not installed. It coverts pdf to some other file types. I need a solution like this to view documents on my site.

Hi jzero. Is it possible to modify the code so that one cannot download or print the document?

Download or Print is a browser function, so is almost impossible to prevent these functions, but you can just render PDF inside a DIV element without any extra resource
Take look on both links bellow

Alternatively, you can try Spire.PDFViewer for ASP.NET. It offers a PdfViewer control to display PDFs in a web browser. You can customize a toolbar for users to set browsing preferences.

That Spire looks good built only costs over $1000...That's crazy..

Isn't there something free or less expensive than that?
