Figure 225 The Properties Dialog Box
Displaying a Dialog Box for Operator Input
VEE includes built- in pop- up dialog boxes with automatic
error checking, prompts, and error messages. They are
located under Data ⇒ Dialog Box.
For example, a program could require the operator to enter
a real number when the program runs. You can include a
Real64 Input object in the program that automatically displays
a Real64 Input box for the operator when the program runs.
The Real64 Input box also automatically displays an error
message if the operator does not enter the correct
information at the prompt. Figure 226 shows the object to
include in the program, and the Real64 Input box that appears
when the program runs.
Figure 226 A Text Input Box
Figure 227 shows the configurable error message that
appears if the program runs and the operator presses OK
without entering correct information into the Real64 Input
box.
