generic vi reference

[Gary1wang]

Hi Guys.

I am new in Labview. I have a subvi that i do not know how it works. Can you guys give a hand. When i hover the mouse on te vi, it says generic vi. It is shown in the first picture below. What does it do, and where can i find it in the function palette.

Its a reference to a VI.  But with it being a constant, it probably isn't going to help much.  That is unless the constant is pointing to the VI it is contained in.

Can you post the VI itself.  I'm guessing that an actual VI will be registered in that spot in another case.

IN the VI you showed I believe it is simply a "placeholder" and is there to allow you to specify an event. THe event as shown will never fire. Somewhere else in that code there is an event that uses a valid VI ref to "turn on the Event".

Search for

"Ton nugget dynamic" and look at Ton's Nugget on dynamic event registration. He uses the same construct in hsi example to "turn on" or "turn off" events.
