Prompt User for Input Details

Note  The behavior of this VI changes depending upon the target. If the current target does not or might not have a host computer connected, the configuration dialog box displays warnings next to options that are invalid without a host. If you configure this VI to prompt for input and run the VI on a target with no user interface, such as the Real-Time Module with no host computer connected, this VI returns an error.

This Express VI operates similarly to the following VIs and functions:

One Button Dialog
Two Button Dialog
