Create type def and then use it

[abandoningcausality]

I'd like to create a typedefed control and then drop it in a new VI. Here's what I have but I get this error:

 

Error 1061 occurred at New VI Object

Possible reason(s):

LabVIEW:  Unable to create new object.

If you want to use the New VI Object VI to insert a custom control you need to feed it a valid path and set the Class input to GObject or a class it inherits from. I would be interested to know if there is a way around this but I think you will also need to save the .ctl (at least temporarily) so you have a valid path to reference.

 

To explain the error you were getting, you were telling LabVIEW to put whatever was at the path "Control 1" into your new VI.  That isn't a valid path so LabVIEW just gave an error saying that it couldn't create that object.

Thank you. I was hoping I could do it without saving the type def as is possible manually. I guess I can't.

I'm pretty sure you could do it without saving.  You'd have to get a reference to the VI in memory, and insert that instead of using it by path, but this design is easier to implement and understand, but by name is probably possible.
