I want to validate strings displayed in a TK application, how can I write rb program to communicate to it and extract the messages from GUI? Any module is good for that? ---

Do you mean about validation on TkEntry widgets? If so, please read ‘tk/sample/demos-en/entry3.rb’. ---

Hi, We have a separate tk based application running(can be initialed by Ruby script), my task is to write a Ruby program to take the control of it and validate the display, function, and browse from gui to gui. It is much like how Watir do to web browser. Do you have any idea how can I implement it? Thanks! ---

Then, please read ‘ext/tk/sample/remote-ip\_sample.rb’ and ‘ext/tk/sample/remote-ip\_sample2.rb’. If you use Windows, you may need Tcl/Tk’s “dde” command. Please read Tcl/Tk’s manual of “dde”. On Ruby/Tk, call “require ‘tk/winpkg’”. TkWinDDE module supports it. To control your Tk based application, you will have to modify your application to register it as a DDE server.
