Testing Modal Windows

Hi,

I am trying to perform some actions on a modal form (click on Cancel button) which opens when i clicked on the green '+' button. I have read about it in http://support.smartbear.com/viewarticle/72921/ . In this topic, it has asked me to use Runner.CallObjectMethodAsync(w, "MyShowModalDialog", "Param1", "Param2") method. But i do not know what is MyShowModalDialog and where i can get it from. Can someone tell me where i can see this name of the form which is modal?

Thank you.
