Desktop can not see the objects in the MSWOR, VIPLET,..

In a Word Document, they aren't objects in memory.... they are contents of a document.... text in a text file.  A word document is just a glorified text file with a bunch of formatting information.

If the VIPLET is the same sort of thing, where you are accessing some sort of document, then it's the same deal. The brief google search I did on Viplet is that it is, generally, a terminal emulator Java app.  If that's the case, then it's the same sort of deal where TestComplete cannot see the individual objects and contents of an RDP window...  The window is the object being investigated by TestComplete... the contents of the window are hosted in a different operating system and not exposed to TestComplete.

Thank you very much for your search on VIPLET, as well as for your very detailed answer to my problem. thanks again.
