Lab 2-2: Creating a Dialog Box for User Input
If it is not already open, open the program
usrobj-program3.vee.
In the Data ⇒ Dialog Box submenu are six choices for dialog:
Text Input, Int32 Input, and Real64 Input, as well as
Message Box, List Box, and File Name Selection boxes. In
each case for text, integer, and real input, a dialog box helps
you configure the prompt or label, default value, value
constraints, and error message. Once you include one of
these dialog boxes, a pop- up input box will appear when the
program is run.
1 Select Data ⇒ Dialog Box ⇒ Int32 Input and place it to the left
of the Function
Generator. Change the Prompt/Label field to
Enter Frequency:. (Remember to click and drag over the
field to highlight it first.) Change the Default Value to 100.
You can also double- click an input field to highlight an
entry.
2 Change the Value Constraints to 1 on the low end and to 193
on the high end. Change the error message to reflect
these new values, as shown in
Figure 45. Finally, iconize
the Int32 Input object.
