I have not tried to do this with the DWF viewer, but have done it with
the MapGuide 6.5 viewer.
If you look at the DWFViewer html files for MapGuide, you should be able
to find the GUID of the desired class (the map viewer).
With this GUID, you can search the registry to find the name of the
In Visual Studio, you can pick the component, by adding a reference, and
selecting it on the "COM" tab.
If you found the right class, it will generate a wrapper assembly that
is also a .Net control.
You can then add the control as a normal control.
You should also be able to see the properties for the control.
There is also a tool to generate the assembly outside of Visual Studio,
but I can't remember its name.
