Putting /dde on the command line (and remembering it in registry) is a standard way to launch an application when, say, double-clicking on an .OPJ file in Windows Explorer. After the application is launched in this manner, it then receives a Windows DDE message with the string [open("%1")], where %1 is replaced with the file name.
Origin can also be launched like so:
"C:\Program Files\Microcal\Origin 6.0\Origin.exe" myprojectname.opj
using the command line. This looks similar to "C:\Program Files\Microcal\Origin 6.0\Origin.exe" %1, where %1 is replaced with actual filename.
I am not aware of how exactly "document management repository via a web interface in Internet Explorer 6.0" attempts to launch Origin (%1 as a literal string would certainly be invalid), but if it does use one of the two methods described above, then things should be fine. Otherwise it is doing something that Origin does not support.
Origin does restore the /dde command line setting in registry on every startup. |
