Notifier

[alre]

Hello, i am now building an application with Labview. I need to read the result data from Sub vi and I used the notifier function. But i can't read data from main Vi. Someone got an idea?

Use "wait on notifier" not "get notifier status". Make sure the names are exactly the same.

Also, please post your code. If you are very new to notifiers, there may be a better way to do what you are doing.

There is also the question of whether or not the Notifier is the right tool to use.  I rarely use Notifiers due to their lossy nature (of you write to the Notifier twice before the read gets around to it, you will not get the first notification).  So I typically use Queues or User Events.

Hi Mike,

have you written the follow-up post that you tease about at the end? I make heavy use of queues in most of my data acquisition applications, and I'm wondering where you're going with it!

[mikeporter]

Yes, keep reading the subsequent posts.

Alrighty, I have not explored the Teststand project too much because I still have not gotten my tortoise svn to play nicely with your repository 😞

It's not teststand, it's LabVIEW. What is the issue? Did you register?

Sorry, I meant the Testbed Application, and I just typed the first test-word that came to mind! I did register for the website (I was never prompted for a password when accessing the repository). My attempt is explained in this comment:
