I recently added this bit of code in my application. As part of my unit testing I was sending a value of "10" to the Pin Number terminal. When the test failed I probed the integer output and was surprised to find the function interpreting the string as binary instead of decimal! It was returning 2, not 10. Took me about 10 minutes to figure out what the real problem is.

Howdy! I am trialing a new model of review for OpenG VIs. I want to enlist the help of the entire LAVA community. If the VI under review is one that you use in your projects, interests you, or you just have a moment free whilst hanging out on LAVA (I mean, where else would you rather be, right?), then please check it out and leave your feedback. The aim is - to steal a line from Christina - to get more eyes on the VIs I am hoping this will lessen the load on individual reviewers whilst increasing the quality of the changes (or proposed changes). This model is based on the assumption that there are a lot of Community folk who would like to contribute to OpenG but don't have the time to commit on a regular basis. The reviews posted may be in the form of specs or actual VIs etc... Feel free to leave your feedback in the form of comments, documents, code (changes, tests) or whatever makes sense! You can get started by checking out the newly proposed Trim Whitespace VI code. The LabVIEW community appreciates your time. Kind regards Jonathon Green OpenG Developer PS - Of course, if you are interested in contributing more to OpenG, please PM me!

The basic difference of course is that a Notifier is a broadcast mechanism. If you have ten threads waiting on (listening to) the queue, and enqueue an item, then only one will stop waiting. I think it will be the one that started waiting first but I don't know whether that is guaranteed. If you have ten or ten thousand threads waiting on a notifier, they will all stop waiting and take the update. With a single element queue, you can't put any more into the queue until the first item is taken out, but with a notifier, you can put as many in as you want, and if the receiving thread or threads don't finish looping in time, they can miss notifications. There is no way for the sender to know if any or all of the recipients have received a particular notification.
