I have a Button control which is not detected by Ranorex, If I'm doing an image comparison of the control in its greyed out and normal state will Ranorex be able to detect it ?
Ranorex is able to handle such a problem. You can use the preprocessing functions of image based recording. Please take a look on our screen cast for image based recording. http://www.ranorex.com/support/screencasts.html In this tutorial is explained how to use image based recording.
