in vb.net is it possible to display a pdf file on a form?
If you're looking to display a PDF without needing Acrobat Reader installed on a client machine, take a look at this:
PDF Viewer Control Without Acrobat Reader Installed
I haven't tried it yet but probably will.
yes, but you will end up using a COM+
A quick hack for this would be to use a WebBrowser control (assuming the client has Adobe Reader installed) and navigate it to the PDF file you want to display.
