Using Enums containing spaces in expressions in TestStand 2016

[NickNZ]

Hi, just upgraded to TestStand 2016f1 today. 

So I created a typdef Enum in LabVIEW.  The enum had mutlple words with spaces for a value.

I then called the VI from the teststand adpator and clicked the Create/Update Custom Date Type from Enum button.

All good so far.  But now I want to use the enum in the expression. 

Locals.myEnumVal==Enums.myEnumName.firstword secondword 

I get an unexpected token syntax error on secondword. 

If I look at http://www.ni.com/white-paper/52330/en/#toc3 I note it has quotes in the value column, where my enum has a value of

[firstword secondword] (0)

where (0) is the enum constant. 

How is this supposed to work? I can't find an example. Help doesn't cover spaces. I.e no examples for a color "light blue". E.g.

locals.myFavoriteColor==Enums.Color.Light Blue

- how do we get this to work?... I assume its something obvious I have overlooked.

Try the Enum() expession function - it's mentinoed in the help topic you linked.

Spoiler

Enum(String type, [String|Number] value) — Returns an instance of an enumeration with the specified type and value. If value is a string, the enumerator and number are set as if by calling SetValString(). Passing an out of range value results in an error. If value is a number, the value is set as if by calling SetValNumber(), SetValInteger64(), SetValUnsignedInteger64() as appropriate for the representation of the enumeration type. Passing an out of range value to a strict enumeration results in a runtime error.

Hope this helps!

Hi Trent

thanks for your reply. I found that and still couldn't figure out what it wanted or how to make it work.

Locals.myFavoriteColor==Enum(Enum.Color,Enums.Color.light blue) still gives an unexpected token. 

Locals.myFavoriteColor==Enum(Enum.Color,"Enums.Color.light blue") - could not find type ".

To me the whole point of the enum is to be able to type Enums. {Prompt for defined enum names...} . {prompt for value string}

So for the color example how to get it to work?

The Enum() method is expecting a string for the first input as well, try:

Locals.myFavoriteColor=Enum("Color","light blue")

or

Locals.myFavoriteColor=Enum("Color",3)

I understand what you mean about the auto complete issue, and there is actually already a CAR (612847) in place improve the auto complete usability for enums.

Hope this helps!

Thanks a lot  for your help Trent, at least I can progress now....

I tried Locals.myFavoriteColor == Enum(Enums.Color,"Dark Blue") Error is expected type String Found type (Enum) Color.

Locals.myFavoriteColor == Enum("Enums.Color","Dark Blue")  also fails as cannot find type Enums.Color.....

Lets say its not that intutive and misses the point of autocomplete alltogether. Autocomplete is currently miss-leading users down the wrong path as well.  I look forward to the CAR being completed.

Hello Nick,

I know you probably found an answer by now, but I wanted to give an answer in case someone else runs across this.  We have a similar situation.

I believe the code needed is 

Locals.myFavoriteColor = Enum("Color","Dark Blue")

I apologize.  I see you did get the answer earlier.

Hello,

I am using TS2017 and the same problem occurs. 

Is there new workaround avaliable?

There is moe scenarios with this breaks, for example when typing 

Enums.MyEnum.%s%d
