UI that is no longer available error occured by calling .dll method from powershell.

骏高 1

I have a powershell script calling about some method of .dll.
When I call the method of the dll, powershell displayed the error below.
"The target element corresponds to UI that is no longer available.(for example, the parent window has closed)."

Question1:
Does this error only mean some control be found before cannot be invoked, for the reason of window be closed?
Any other reason may cause this exception?

Question2:
Besides that, the powershell script still executed although error occured.
Is there something wrong with powershell executing?
Or is there some setting options about powershell executing options?

Question3:
Error such as throwed from .dll can be catched by powershell script or not?
If so, how can I catch the error in powershell script?

Without knowing some basic information like; what dll are you calling; what parameters are you passing to it; what do you expect the dll to do; have you consulted the dll's vendor's documentation for programming examples; etc, etc,; it's going to be impossible to tell you what (if anything) is wrong.

Try using a try/catch block and see if that intercepts the error.
