Hello I have solved my shared variable buffering problem and posted the solution (in fact my error) on ni forum : http://forums.ni.com/ni/board/message?boar...mp=true#M291094 One solved problem, one :-) Boris

Hello to you, leopards... I posted a technical topic on ni.com (http://forums.ni.com/ni/board/message?board.id=170&message.id=291094) which explain a shared variable buffering problem. In this post I didn't discuss the OS depending issue to not worry windows-only users (not rare in ni forums !...). I get the chance to do it here in our small place of peace. What network protocols work on mac ? - PSP (shared variable) : Yes. I read that it's ok for read/write with datasocket VIs but that you can't deploy the Shared Variable Engine (SVE) on a mac (no deploy of the shared variable library). When needed, I thought I could deploy the library on a distant PC (the programmatic deploy method allow that. I didn't tested yet). You can't use the sharedvariable node but datasocket VIs allow to do the same. You also have access to a "wait" ability when reading data (get data only when an update is available). - DTSP : I think it doesn't, but I'm not sure. Perhaps the same limitations as PSP (read/write only ?) - TCP : yes but it doesn't have any buffering ability (I kno I could emulate something but it's long and hard work) Do you have information or experience using something for multiplatform network and buffered communication between executables ? Thanks Boris

QUOTE(PJM_labview @ Apr 24 2007, 03:17 PM) I tried remote debugging, but labview crashes ("fatal error occured during operation, closing connection") during connection to the remote application (after many warnings such as : 'The class expected to be at "Macbeth:Users:boris:Desktop:builds:projet:My Application:Application.app:User.lvclass" was loaded from "Macbeth:Users:boris:Desktop:builds:projet:My Application:Application.app:AppContents_ppc.llb:User.lvclass".') QUOTE(Aristos) The known issues for 8.2.1 recommends that if your build does not work, you should try changing to Do not disconnect type definitions or remove unreferenced members on the Additional Exclusions page of the Application Properties dialog box. I used this option without success. QUOTE(Aristos) If you are willing to share your app, please contact NI tech support and file a bug report so we can debug your app better Could you send me a message to let me know the "procedure" ? Thanks for help :worship: Boris

Helloooo, I use LVOOP, 8.2.1 with app builder on a G4 mac. I build executables which contain objects and dynamic VIs created using LVOOP. I used the "do not disconnect type efinitions" option. The executable crash at load time. Is there any way to know where the crash comes from ? Building of executables is quite long so I would like to find a nice strategy to find out the cause of the crash... Thanks for your help ! Boris

Hi Tomi, As far as I tried 8.2.1, many LVOOP bugs are fixed. You should be convinced. QUOTE(Tomi Maila @ Mar 1 2007, 05:14 PM)

I encounter the same problems than jimi since I added LVOOP in my project (about 300 VIs) : crashes after run arrow hit, save all, open a project... I used GOOP for a while, and chose to switch to LVOOP so as to "enjoy" NI support, full integration in the project manager window, speed, and easier learning fo engineers/students we recruited. I didn't know it would be such a crashing nightmare... I should probably choose to recode everything we did with LVOOP in GOOP. I'd prefer to see if these workarounds could save me until bug fixes is released. Consequently : - We want NI to know that WE NEED THIS BUG FIX SOON. A 8.21 WEB release would be good for us (even if some people would complain about mass compiling) and cost nothing to NI. I'm embarassed to say to my engineers : "yes, we use LV. I chose it. We paid xxxxx$ for it and it's not working at all.". I won't bear it for long. - How can I do this "ctrl+shift+run arrow" stuff with my macs ? when I do "Apple+alt+run arrow" nothing executes but my vi seems to be modified since it gets an "unsaved" * mark. I thought there would be a "mass compile" pop-up ? Boris As angry as Jimi !

Hi, I'm quite familiar with xcontrols, but I'm facing a new problem : After a "transfer" between macs (development and deployment machines), two of my xcontrol became impossible to unlock : the "Unlock library for editing" doesn't appear anymore, and when I ask "Why is library locked", I get the following answer : "You do not have the correct license to be able to edit this library". I've got an FDS 8.2 license, app builder 8.2 (on both machines), and didn't change any license thing since LV 8.2 release... I tried to reinstall LV... I tried "Save for previous" and then "Save" again... One of my mac is an intel-chip one. It could be the problem, but I'd like to be sure of that, and get my libraries unlocked... and I don't see any way to do it. Has anyone ever seen that ? Thanks Boris

I got 33 ! Some questions are tricky. Some are useless (if you don't find the "change to indicator" with a right-click on the BD, you do it on the FP...). And some are for windows-users only... I never used DAQmx !... Anyway, it's quite exciting to pass tests. I hadn't since I left school a while ago!... Do you think I deserve a christmas present from my mom with a 33/40 grade ?!... bo

Hello Spacetoon, I'm afraid that everybody here think : "what you are trying to do is basic programming"... for which you probably don't need help. You just need to buy a book or search through examples to find a way to program this. The "little light" next to the Run button in the block diagram could be useful too. It will show you the way Labview run. I can't send you code since I use 8.2 but it will probably be more "learningful" if you do it by yourself. Use Events structures to do that nicely (you can find good examples in the help) ! Happy wireworking ! Bo

I tried on a G5 10.4.7, LV 8.0.1, and on a Powerbook G4 10.4.7, LV8.0.1, to read files from PC hard drives formatted in FAT 32 and NTFS (both don't work). I had problem with file transfers in my network in the past (strange things such as file not readable anymore after transfer) and I probably should search this way... Thanks for the test anyway :beer: ! Boris

Hello P'tit Bras (je dois

Hi Ton, Thanks for your post. I get alternatively an error 10 or an error 7 depending on the open vi I use (config file, file,...) I tried with a simple vi and I get an error. I also tried to use a read-only option, and there shouldn't be any right access on this drive. When I ask them in the Finder, I have read/write permissions. What is strange is that I'm able to use the list folder vi with no error. If I use the output to build a path and then open it I get an error. You're right, it should be an access rights problem... but I can't figure out how to solve it... Boris

Hello guys, I have many computers acquiring datas, and I need to read and write these datas from a single ethernet hard drive (LaCie 500 GB, FAT32). On a Mac G5 with LV8, once the ethernet drive is mounted in the finder, I try to read a simple config (or text or binary...) file in labview, but I get an open/create/replace file code 10 error. I've got the same behavior with a file located on a PC hard drive (mounted in the Finder too), but I don't have any problem with a file on a Mac hard drive. It works when I try the same from a PC with LV8. For me, all this tells it's related to smb/cifs stuffs... I tried manual path entries like : "file://Volumes/GRESSENSGRP;U676-BACKUP/Datas/file.txt", etc... but nothing works. I didn't find the same problem in the forums... Any idea ? thanks Boris

Ok Dave, you're faster than me... I didn't know the "link to" stuff in app methods or property nodes... and was doing all that with three property nodes... Thanks for the tip again ! boris
