How do I set data range to a strict typdef through the control reference

[Vignesh1987]

Hi everyone,

I am trying to set data range to a strict typdef through the control reference, when I do so I get an "property node error".

Is there any way to set range to the strict typdef.

Thanks,

Vignesh

Try setting the original (type-def) control, and not its instances.. to open the reference of original type-def control, use 'Open VI Reference'.

Edited:

These properties are not available with STRICT TYPE DEF.

a. Data Entry Limits:Increment Property

b. Data Entry Limits:Maximum Property

c. Data Entry Limits:Minimum Property

Hi Vignesh,

no, it's part of the typedef.

Use a normal "non-strict" typedef instead when you need different input ranges for several controls made with the typedef...

Just to add a little bit to Gerd's comment.  You cannot change the properties of an instance of a strict type-def.  When you put the strict on the type def, it locks down the properties.

Hi,

I'd like to follow up on this one.

I understand the difference between a strict and regular typedef, but I was wondering why isn't there any intermediate options. For example, when using an image display control the X and Y ranges are part of the strict typedef, so you can't change them, but if you set the type to regular _EVERYTHING_ (except the data type, of course) can now be changed so you need to hand-tune every control instance for the right size and everything. Interestingly, even for a strict typedef the X and Y ranges change with different image sizes. I don't understand what's the logic behind this?

Consider an analogy: your cars has two-position knob - a) go straight, no steering at all; b) four independent steering wheels for each wheel...surely there are better ways <:

Isn't there a way around this limitation?

Hi Lukas,

look up the LabVIEW Idea Board, there are ideas related to your question...

One of the more useful LV facts I learned early on was that stricts are typedefs with all properties locked. Being able to change properties of a strict means it's no longer "strict". Just my $0.02
