Change the VI History programmatically

[JoergLee]

Does somebody know how I can change the history of a VI programmatically?

I like to add a text to every VI History in my Project, with a VI call.

Also I like to change old histories sometimes.

Ciao Joerg

Hi Joerg,

reading the revision history can be done like shown in the screenshot:

 

As far as i have seen the revision history cannot be altered programmatically.

hope this helps,

Norbert

Thanks,

but how das NI add new messages into the History (changed subVI, LabVIEW update)?

There must be a opportunity.

Its only a user restriction from NI.

Joerg,

a short excerp from the LV help:

Because the history is strictly a development tool, LabVIEW automatically removes the history when you remove the block diagram of a VI.

I assume that  it was a design decision to prevent programmatic access to the history by the user.

If you don't concur with that, you could either file a product suggestion using the product suggestion center or you can use custom implemented ways to solve your task. 

hope this helps,

Norbert
