Chapter 6

Using Buzzsaw with Autodesk MapGuide Viewer

Appendix: Buzzsaw Code Integration

The following code sample illustrates how to integrate Autodesk MapGuide
and Buzzsaw so that you can avoid the need to authenticate the Buzzsaw
interface, retain the current map state, and prevent the non-secure site
warning message from appearing. See the preceding section for more infor-
mation about managing these three elements of the interface.

Note The URL parameters to the OBJECT tag have to be specified before the
sample will work. Also, the CODEBASE parameter to the OBJECT tag should be
either specified or removed. The cookieNameXXX variables can be changed to
give unique cookie names for multiple MapGuide applications stored in Buzzsaw.
