Well, if you're using a web browser control in one of your forms to do this, I guess you could override your form's WndProc method and look for WM_SCROLL messages and just eat 'em. By that I mean not passing them on to the form's base WndProc method. Another option might be to use a 3rd party library to render the PDF file, like PDFNet. This would also eliminate the dependancy on the web browser control and give you greater flexibility over what the user can see.
