Autodesk DWF Viewer discussion group member, J_S_W, developed an ASP.NET application that displays DWF files stored in an Oracle database. It was working, but one day it began to simply bring up a blank Internet Explorer page when he clicked on the link for a DWF file. The strange thing was that the links continued to work using FireFox on his PC. The links even continued to work in Internet Explorer if he opened the DWF file directly (not the one in Oracle). The links also worked using Internet Explorer on other PCs.
J_S_W received the solution from one of the Microsoft developers on the ASP.net forum. It turned out that Microsoft's Visual Studio 2005 is the problem.
J_S_W had Visual Studio installed on his PC which is why he encountered the problem with Internet Explorer while other PCs running Internet Explorer did not. The solution was to Delete (or rename) the
"HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.aspx"
key from the registry. Apparently this key causes a conflict with a number of software packages, including the Autodesk DWF Viewer, and prevents them from automatically starting up in an ASP.net web application.
Hey J_S_W - thanks for sharing.
