API call - get a measurement/value

[Lars Uffmann]

Hey everyone!

I just started having a closer look at LabView (not impressed with the
sloggish performance of my system since I installed the development
environment, but that's different topic).

Anyways - since my googling skills seem to be failing me this time:

I want to use an API call to fetch a measurement value from another
software (that provides the API). Then I want to display that in a graph.

So - can someone point me to the right control for the LabView block
diagram?

Edit: I just found the "Call Library Function" is that what I need?

Best Regards,

Lars

Yes it was. Is this newsgroup dead?

No?

No?

Ok - I need to rephrase: Is this newsgroup dead, when dead means
"extremely low traffic" as in less than 1 post per week avg.? :)

Thanks a lot for pointing me there - I wasn't aware of the auto-mirroring :)

I managed to get my DLL-call done with the Call Library function, so I
didn't check the newsgroup for replies either, for a while.

So thanks again!

Best Regards,

He may be posting to the actual LabVIEW newsgroup. At some point it
was synchronized with this board. Then that broke. It may have been
restored but maybe only one way from nntp to this board but not
backwards.

Exactly that is the case. I wasn't aware of this mirroring function
until Laura kindly pointed it out. I guess this functionality should be
restored to work both ways.

Why would anyone use a newsgroup?
Isn't it a lot easier to connect directly through NI.com?

I know I'm starting a debate that I probably better shouldn't, but to
enlighten you: No, it is not easier. Newsgroups work from my newsclient,
which I use all the time anyways.

Many technical groups - one software to access them all, and one
account. Websites = many accounts, many links to remember/bookmark.

If you're serious about the whole thing, newsgroups are the way to go.

Have no idea why anyone would use an ordinary newsgroup client.

I think that is part of the problem of Web 2.0 :)

Most don't allow you to attach files.

That is merely a matter of configuration - binary or non binary. And
attaching files to newsgroup or forum posts is ususally a bad idea
anyways - just link to the source on the web. The one downside to this
is of course that you need to find a host for self-uploaded files, so I
can see why you find a forum convenient.

And @all: Yes, the mirroring-software did create this "account" here to
mirror my posts. I am not a registered user of this forum, nor do I wish
to sign up unless I really need to, at some point :)

Don't use whatever newsgroup you are using. Just log into NI.com and
go to Discussion Forums. This is homebase. There are hundreds to
thousands of messages a week.

Read & understood. I'll use the forums if I have urgent need for an
answer. Or just post to the newsgroup and read responses on the forum,
now that I have the link.

Best Regards & thanks for all answers (which weren't available to me
until now). Btw - I called NI support and they didn't mention anything
about the mirror between forums and newsgroup, so maybe this is
something only semi-official.
