Questão 13
Questão
A VI has Automatic Error Handling enabled. It calls a SubVI that has Automatic Error
Handling disabled. The Error Out terminal of the SubVI is unwired in the calling VI. The SubVI
returns an error to the calling VI. Will an error dialog be posted because of Automatic Error
Handling?
Responda
-
Yes, since the Error Out terminal from the subVI is not wired in the calling VI.
-
No, since the Error Out terminal from the subVI is not wired in the calling VI.
-
Yes, since he SubVI has Automatic Error Handling disabled
-
No, since the SubVI has Automatic Error Handling disabled
