I'm trying to script a save of a pdf doc inside IE. It seems difficult. Iwebbrowser2 does not have any apparent access to the acrobat control inside of it that I can get to. I have experimented with trying to directly send windows messages to the adobe plugin, to no avail (probably can make it work, but its going to take some digging).
ExecWB looked promising, but if you are viewing a pdf file the save/save as is grayed, consequently failes using iwebbrowser2. Print will work, but I need to print to a file, and that has proven surprisingly hard (most print to file stuff, does conversion, so it slightly blurs the pdf images).
