Communicating Between Framesets &/or Windows

[andromeda]

Hello,<BR><BR>I'm building an application with the IE tree control within a frameset. I need to be able to communicate (call methods to update tree nodes & select the appropriate tree nodes) from the main window. Does anyone have suggestions on how to do this &/or examples. Also, would it work the same for calling functions between windows? I need to be able to take advantage of the fact that the tree is a server control, so if possible, account for this when responding.<BR><BR>Thanks a bunch!<BR>Willamette
