title: Programatically fill PDF form fields in Browser Control
body: <p>Basic scenario is that I need to programatically fill out a PDFs text fields that resides on a webserver. The fields will be mapped and filled out with data contained in a CSV. The PDF must be opened in the browser (browser control or ie/ff/chrome/etc) and edited in place. Cannot be downloaded, filled out, and uploaded (it must be filled out and submitted using the submit button in it; I've tried editing the buttons submission path to no avail).</p>
  
  <p>Thus far I've put a web browser control on a form and made it navigate to the website, login, and load the PDF file. How do I interact with the PDF file thats open in the web browser control? Looking through various PDF libraries, they seem to mainly interact with a closed pdf located on the harddrive, make the modifications, and re-save it.</p>
  
  <p>EDIT: Im very open to alternative solutions. I dont know if its possible, but if so - PDF based javascript on my machine that I run on the form? I can do this easily if I download it, but dont seem to be able to find a way to use PDFJS while its open in the webbrowser.</p>
