After hopping around a bit, we end up wanting to download a PDF file. But instead of downloading, the file is displayed within the webBrowser control, which the user can not see. How can I download the PDF instead of having it load in the browser control? Add a SaveFileDialog control to your form, then add

But if I go to, for instance, Google and set Google Instant on, and then search anything and navigate manually through the next button several times, the memory used by my application will start increasing.
