How to use ‘Activate’ control?
Refer this post,
Activate Activity - Enables you to activate a specified UI element.
You can use it on application which you want to get interact for further your operations or actions to make it active.
though you can even work without of it by using perfect selectors as well but dedicated Activity is simpler to use.
Important Note- You don’t need to use this until and unless you want it
because with most of the available activities inside uipath studio comes with a property calledActivate.
Once you will check it that activity will make sure to active your control before to perform any operation with that control.
Get Active window will return the Current active application window ` though we can use the Returned window pointer to Activate activity but Only Get Active window won’t activate your particular window.
