Bug in vertical slide control? (LV 7)

[AeroSC]

Try this: Create a vertical slide control with text labels (say 5 values). Uncheck 'sequential values'. Change the values to some higher numbers (say 100-104). Create a numeric indicator and wire it to the slide.

Now the fun part: The indicator will read '0' until you move the slide the first time. After that, it will read the value assigned for that text label.

This problem cost me 2 days trying to determine why a code that had worked for 2 years wouldn't run on a new machine. The slider controls in it were passing the wrong values to the DLL calls. Is it a bug or just the way it has to work?

This is how it is supposed to work. The value isn't changed when you change your scale on the slider. In this case the slider cannot show you a good indication that the value is off of the scale. If the digital display is shown, you can see that the value of the control will be "<0>" indicating that the value is 0 and it is not a "legal" value on the scale.

In addition;

If you want the value trunckated, you also have to set the data range.

I observed that behavior with the <0> on the digital display. However, I can't think of a reason why I wouldn't want the value to update if I change the scale.

This way, you have a choice, if was done automatically, you whouldn't have
that choise.
