Webbrowser1.Navigate("http://mysite.com/test.pdf")
XP WEBBROWSER-CONTROL: brings up PDF embedded in webbrowser control, as desired.
XP IE7: Behaves the same if you manually navigate to URL, as desired.
VISTA WEBBROWSER-CONTROL: brings up PDF by separately launching Acrobat, won't embed in webbrowser control. Not desired.
Vista IE7: embeds PDF properly if you navigate to same URL, as desired.
I am using Acrobat 9, where there is a preference setting under Internet to bring up PDF embedded in browser -- works fine directly in IE7, but not in webbrowser control.
I want the PDF to come up in the webbrowser control in Vista same as it does on XP and Vista IE7.
I have looked at every property/method/event in webbrowser control and can't find any settings that would matter. I have tried to find some Vista setting that would be relevant, can't find one.
