@Rastek - I am actually looking for the name of the add-in that would work for such applications. The add-ins that I have currently, is not doing the job.
@Rajkumar - I have tried with the Java add-in, but there is no success. As you said, maybe these are custom built MFC controls. I have requested for this information from the developers. However, now I know that it would not be possible to automate them. Thanks.
