Foil 26 Tango supports Microsoft NetMeeting

From Tango 1.4 Done with Pictures CEWES(ERDC) Tango Traing -- Sept 16-17 1999. by Geoffrey C. Fox


1 Microsoft currently supplies NetMeeting for Windows 95/98/NT
2 This supports a different model for sharing
  • When you share Word for example, there is only one copy of application running on the master
  • In Tango classic shared event model, the application (e.g. spring applet) runs separately on each machine
3 At its simplest, NetMeeting shares the "display" (frame buffer produced by application)
  • This explains curious hatched area on following page. This corresponds to part of Word window that is obscured on the master but not on the slave.
4 NetMeeting captures mouse and keyboard actions in the shared window and treats these as shared events
  • This allows shared editing with a difficult master-slave model
5 This is an example of Tango interfacing to a C++ client application -- Microsoft's NetMeeting
