Convert project item type string to type GUID

[raphschru]

Hi all,

Is there a generic way of getting the type GUID associated to a project item type string ?

Also, I don't necessarily have an instance of the project item in my project, so I cannot use directly the ProjectItem property "Type GUID".

Example:

"Elemental IO"          gives  "{A117026A-AD51-4C63-8341-085C842E9D22}"

"Library"                    gives  "{ABC740D6-F254-4BBC-5675-8858F35B820E}"

"FPGA Base Clock"  gives  "{EF04866F-AE99-4C3F-B28B-879B709E5BBE}"

…

Second question to go further:

Are the type GUIDs always the same for a given type string ? Or is it dependent from projects or LV versions ?

For example, will items of type string "Elemental IO" ALWAYS have a type GUID of "{A117026A-AD51-4C63-8341-085C842E9D22}" ?

If the answer is yes, I could definitely have an hardcoded conversion table and the problem would be solved 😅.

Thanks.

Not that I know of.

You can use ProjectItem - LabVIEW Wiki, and indeed make a lookup VI...

The GUIDs seem to be stable across version. These GUID serve a purpose, and it would be inconvenient for everybody including NI to change them. There's no guarantee though. If this is a good reason for NI to change them, they will change.

Even if those GUIDs change in a future version, you can make a hardcoded conversion table. That would solve the problem. If they change, you can use a conditional disabled structure to make the table version sensitive.
