Change Variant type name programatically

[Steffen_Zienert]

Hi,

I use Variants to communicate between Queue State Machines similar to the Queued Message Handler Template. These Variants have type names which I use to distinguish between different values. I don't know how I can change them programmatically. At the moment I use String constants with static labels. The problem arises if I get the String from a VI, then I can't change the name.

Here a more elaborate example which is more similar to what I am doing.

Type cast into the same type but label the constant you feed into the type terminal (also a quick and dirty trick for named probes which is how I found out about it):

Using Coerce to Type is safer, as you know it's not going to reinterpret the memory.

"Coerce to Type" is available in 2017 (and earlier). It's just not visible in the palette: https://forums.ni.com/t5/LabVIEW-Idea-Exchange/Officially-Support-quot-Coerce-to-Type-quot/idi-p/121...
