QUOTE (El_Frito @ May 30 2008, 12:46 PM) Post example to get better advice. If you are using Filter Events then an earlier executing filter event could discard the event and therefore the other events will not be fired. Event are handled in the same order in which they are decalred. Just want cmoes to mind. Ben

QUOTE (Justin Goeres @ May 30 2008, 10:01 AM) If you know the words or phrases in the post then searching may be fine. Tags let you define key words that do not appear in the post. Once the tag DB is built-up the tag clouds will show the most common tag in bigger font. Tags that appear in the same post are related, so... If you tag strategically, you could over time create a tree of related tags to drill down to a topic that you want. Others that do not know all of the key words could browse to a good post by drilling down. http://forums.ni.com/ni/tagging/view_tag?tag.text=LabVIEW_Performance&tag.message_scope=all' target="_blank">THis link in the "dark-side" shows if you start with LabVIEW then you can click on LabVIEW_Performance to see links that speak about performance.

I love Tags ! Cool ! :thumbup:

QUOTE (Yen @ May 30 2008, 01:37 PM) Hmmm... this has to be investigated, indeed. Other point is that I can't find how to open a ref to a VI in a specific project/context. If someone can clarify the difference between a context and a project, that would help me to understand. QUOTE (Yen @ May 30 2008, 01:37 PM) As a minor point, if a VI is in memory, you can use its name to open a reference to it instead of its path. Makes you less dependent on its exact location. If I only give the VI name I get error 1004 : LabVIEW: The VI is not in memory. To load a VI into memory with the Open VI Reference function, a path must be wired for the VI Path input.

QUOTE (Yen @ May 30 2008, 12:34 PM) I have.. . Using the the "get ctrl value" method works (*only* if the FGV's front panel is opened) but it make me think that the VIserver settings (port, VI access list, etc.) are correct, so the reference to the FGV is fine. The "call by ref" method give no error at all, but I think that I am getting a reference to "another instance" of the FGV because if I add a "write" case using the "call by ref" method, project B write to the FGV and reads what it wrote, the same for project A. How to do to have only one instance of the FGV and each project refering to it? See attach code corrections to do before running : - in B project, in the VI B_reader_loop.vi change the "shared FGV's parent dir path") - on both project adapt the port number to your setting (mine is 3385) http://lavag.org/old_files/post-7452-1212145549.zip'>Download File:post-7452-1212145549.zip EDIT : Ok Neb,Yen, I am just seing your posts now, I will try that. In the end opening a reference to the project (which is a labview "context" if I understand well) sounds the correct way to do. Referring to LabVIEW turns out to open another instance of the pointed VI in the separate LabVIEW "context" that is the second project. It's cool to learn, thank you guys ! Yen, I set 3385, because my labview 8.5 is set with 3385 * : I am not sure that "context" is the appropriate technical word for what I mean... I am not a proper software engineer (I use to be thermal engineer )

QUOTE (Antoine @ May 30 2008, 06:08 AM) I have not done this LV 8.+ but I thought about it when the proj was introduced. I believe Opening a ref to the proj that has the VI and then find a ref to the FGV running in that proj. Watch for name mangling if in a library. And yes use call by reference. Ben

QUOTE (Yen @ May 30 2008, 11:27 AM) Hi Yen, Thanks for the link . I implemented the "call by reference" like in the example you pointed, but it just doesn't work and returns no error.. is the there any particular settings to set on the shared FGV to make it work ? Side remark : When the 2 apps are on the same PC it seems to me more difficult than doing it with between a host PC and a RT target. I say this because I did it 2 years ago quite easily with LV 7.1 and I was expecting it to be straightforward.. Is there a significant change on this between LV 7.1 and LV 8 or is it just that I missed a detail of some kind ?

Hi all, As mentioned in this thread, since LV 8.2 it is not possible to share a queue between 2 LV instance. I have to LabVIEW projects (A.lvproj and B.lvproj) running on the same machine and I'de like to make them communicate by "sharing" a FGV. Basically : - the shared FGV VI is in project A - at start, the FGV is set to be accessible using VIserver - on certain event a value is put into the shared FGV - project B opens an application reference using IP and port number (the same set by project A) - project B opens a VI reference on the shared FGV to read a control value I must be missing the point because it only works if the FGV's front panel is opened... see my code below Can anybody help me on this ?

QUOTE (PaulG. @ May 29 2008, 01:24 PM) I've used WebExMeetMeNow to code in LV with no issues. Wild guess: Could this be an auto-tool selectin issue? Done guessing. Ben

QUOTE (jpdrolet @ May 29 2008, 02:36 AM) Nice example.... and only with scripting, we can watch what you have done

QUOTE (Yen @ May 28 2008, 02:15 PM) Well I have to admit you taught me something I never noticed! So it looks like an older version of LV is the best guess yet. Ben

Nah it can't be an older version since there is a project drop-down. Don't worry Yair, you are trapped in LV 7.1 land so we'll let that one slide. My only guess is that those are over-lapping wires not the same wire looping over itself. Ben

QUOTE (Michael_Aivaliotis @ May 28 2008, 04:09 AM) Hmmm.... How did you get what looks like loops in the wires? Ben QUOTE (TobyD @ May 28 2008, 11:44 AM) Did you enjoy etch-a-sketch as a kid? Etch-a-sketch frustrated me as a kid because I could not render a circle. I really think that Trigonometry is a pre-req for etch-a-sketch use. Then all the kid has to master is producing a sine wave with one hand and a cosine with the other. Ben

QUOTE (Michael_Aivaliotis @ Dec 2 2006, 05:24 AM) CRELF is first again! If you check out the most recent NI Instrumentation Newsletter (Q2 2008) you will find that CRELF has written up a nice article on Fuzzy Wires. Does this make him the first LAVA member to get an artilce published in the Newsletter? I believe he is the first LabVIEW Champion to do so. Congratulations Chris! Nice article. Ben Where does he find the time?

QUOTE (JDave @ May 27 2008, 12:43 PM) I believe it was Goedel (sp?) that showed that a system could not be proved from within itself. Being an element within the system "universe" we should not be suprised to find that we can not prove this system. I think it was in a book "Five Scientist and Their Gods" that I read that one of them thought the universe was a giant quantum computer that was executing God's program. Just my 2 cents, Ben

Say I wanted to deploy Tomi's example as an exe that would allow other shapes to be added latter (example:customer wants an octogon added)... from what I understand I would have to re-compile the library that houses the class. Are there any other things I'd have to adjust to allow for the addtion of other shapes (aside from the menu that allows which shape to drop)? Ben "sneaking up on OO one concept at a time"
