multiple needles on gauge/meter

[faustina]

Is there a way I can programmatically determine if a gauge/meter has more than one needle?  All I have is the ClassID and possibly the CtrlRef.

hi faustina,

  The gauge's property NumSliders will give the count of needles...

Thanks and regards,

I'm running LabVIEW 2009 SP1.  I don't see this property anywhere in LabVIEW Help.

Can be done like this.

Like this...

Thanks and regards,

The blue in the top bar of the property node indicates that is a property only available if you have scripting installed.

Scripting is not a feature in LabVIEW I'm familiar with.  I have the the professional developmental version.  What toolkit/module do I need to install?

[Dennis_Knutson]

Why are you ignoring the example from aeastet? Did yu even try it?

[Darin.K]

Allow me to take the liberty of using my own snippet tool so that aestets' nice solution is not mangled by the LV snippet tool.

Look like something worth trying now?  Not that you shouldn't install scripting, for that see the LabVIEW API page.

Edit: I see you only have the CtrlRef, then you really should be using aestet's solution....

See this first:  http://forums.ni.com/t5/LabVIEW/What-is-Labview-scripting/m-p/824083

Bottom line: If you don't have a good reason to work with LV scripting... don't.  And it looks like you have a simple solution so why not just use that?
