[HowTo]Use Pane method "SetScaling" in runtime engine

[Olivier-JOURDAN]

Hi all,

In LabVIEW help it is write that "Set Scaling Mode is available in Run-Time Engine (in read and write)...

I try to use this method and :

- 1 - With teh first code (see ScalingFirstMethod.png)
* It's working well in LabVIEW execution
* It's NOT working in RunTime Engine execution (you obtain error 1044 --> VI is locked)

- 2 - With teh second code (see ScalingSecondMethod.png)
* You don't have error in LabVIEW execution
* You don't have error in RunTime Engine execution
--> But in the 2 cases the mode set is NOT apply !!!!!


If anyone as a solution... This method is essential for my UI, so...

Thanks in advance,

OJO

PS : Config : LabVIEW 8.2.1 + Windows XP

Hi Ojo,

The error 1044 are documented on the web :

Error 1044: The VI is locked
When running as a standalone application, a Property Node in the VI might return error 1044, which causes the called VI not to be opened and the application to run incorrectly. However, the application runs correctly in the development environment. You might experience this warning with various different properties, such as Front Panel Window:Auto Center. To avoid the error, you must set these properties in the VI before building an application. Setting properties like this is considered editing the VI, and editing VIs is not allowed when the VI is built into an application.

You can try to add "open reference" function, that can be resolve this problem.

Can you post the two LabVIEW exampel you have made, it's more easy to find a workaround with your application.

Hi, thanks for the answer.
Like I wrote in my first post (cf attachment nammed ScalingSecondmethod.png) I already tryed to add open ref... Unfortunatly scaling mode is not applyed...

I add the two examples, if you find a workaround...

Hi Ojo,

There is no workaround for your problem because, this property can't be write in a EXE, this property can be only read in a EXE and write in edit mode. You can try to delete the first property (there write the data) into the loop, and you can see no error.

I have found another forum with similar problem :

you have the same conclusion than me... and it confirm that the LabVIEW help is incorrect 😞
