QUOTE (Yair @ Jan 7 2009, 02:37 PM) Good, don't! One of my associates (did you meet Tim at NI Week?) flew to another city to do some consulting to help optimize an app that the customer simply could not get to run as fast as needed. He tossed that dynamic data, tested the modification, and switched to an earlier flight home. "He went, He saw, He re-wired" Ben

QUOTE (george seifert @ Jan 7 2009, 01:00 PM) That is the cluster returned by the "flatten Pixmap.vi". You can use the other function of the "graphic Format" palette to rad the original image from file. Ben

QUOTE (ASTDan @ Jan 7 2009, 09:26 AM) That would put LAVA in a position of thretening NI's revenue stream, "Bad, bad, bad" (Rolf Kalbermatter, when realizing that rings used a 16 bit internal representation) Even if it wasn't competition like LAVA-Certified require CLA first, 1) Who would do the evals? 2) How would they be compensated?

QUOTE (Yair @ Jan 6 2009, 12:36 PM) For the sake of passing the test, remeber Yair's reply. [Rant = True] That Q always drives me nuts! If the answer was chart, I would not freak so much. But is says "Waveform Chart" and under the right conditions it will plot at arbitrary intervals. At the local NITS they were running these question on the screen while we gathered. When running across the "coercion dot" question I mentioned it was wrong after giving the answer the test wanted. Since the facilitator was curious he had me stand-up and explain myself. For the novice LV user this type of stuff doesn't matter much. But for myself, I am embarassed in NI's behalf. OK I fell better now. [Rant = False] Ben

First fix: Place any dynamically called VI inside a Strict VI reference, this will force the builder to include the dynamic VIs inside the executable. One question, were you able to build the executable inside 8.2? Ton

QUOTE (Jeffrey Habets @ Jan 3 2009, 04:28 PM) Jeffrey, I had not tried this before, but decided to give it a whirl as I see LV classes being a great interface tool for the FPGA. I put together a simple class to talk to my FPGA, but did not run into the problem you described. I have attached my project files for reference. Can you give these a try and let me know what happens? http://lavag.org/old_files/post-3370-1231200448.zip'>Download File:post-3370-1231200448.zip

QUOTE (Variant @ Jan 2 2009, 09:52 PM) Save Instrument, will link all items in memory to the new path, you only have to resave them (just as the menu option). Ton

QUOTE (sam @ Dec 31 2008, 09:36 PM) There are reasons auto-populating wasn't in the first releases of 8.x :ninja: . The only reason I can see someone is using auto-populating is when you create VIs outside of the LabVIEW project. Why? Maybe you should write your own Auto-Pop routine? Ton

I never had this issue (thanks to the good cross-linking dialog in LabVIEW 8.2+). So I never tried _svn, but use_svn_directories wiki entrance made me thinking. If I search for _svn it looks like I started the rumours Ton

I would try to get a clean repository, the easiest is to commit everything to the repository, remove the .svn folder. Then set SVN to use _svn folders instead of .svn folders. ( I know this is possible with TortoiseSVN). Now if you open up a VI with false links, LabVIEW will start searching (but will ignore the _svn folders) and you can relink. Ton

Hi George, You may want to take a look at the series of messages I posted in this thread on the dark-side. That example is a kind of "worse case" example where I slammed most of everything in there. Re: The data you present to the 3d graph. Every method will interpret the data differently. What helps me out is to just use a small manually entered data set (4-9 points) and pok at it until you see how they are used. 3d Graph Developer note: If you want to change some property of the graph, its plots, etc. first find it using the 3d Graph property dialog. The required property/methods nodes will have to be of the same form as the dialog. Anytime there is more than one property, the "Item" property (1 based not 0 based) will let you select which one you are after. Ben

QUOTE (Justin Goeres @ Dec 31 2008, 09:21 AM) Framing errors are (provied the baud rate, parity and num start/stop bit is correct) an indication that the signal on the wire is bad. This can be wire-run too long, external noise, bad grounds etc. If available I suggest putting an O'scope on the recieve line and inspect the data carefully. Ben

Scroll the table, then delete the strings of the 'old' cells. Delete all data after 10.000 messages or so. Emptying the strings will limit your memory use. Ton

QUOTE (lenny wintfeld @ Dec 29 2008, 11:48 AM) There will be a reference to the project in the 'Recently Used' list, but otherwise no references exist to the project. Here's another way to get rid of the projecrt. >>

QUOTE (Rammer @ Dec 29 2008, 02:46 PM) Ideas off top of my head... 1) Use an active cell of -2,-2 to write the default color and only explicitly write the cells that are different 2) set Defer.FP.Updat = F prior to setting the properties and then un-defer the Front Panel update when you are done. 3) Addition to #2 above. Set the table to not visable after the defer, but before the changes.... Ben

Hi Hanade, the time and effort you put into questions looks kind a low. You don't describe your question clear. You use no interpunction. If you hand over an exam to your teacher you will get a 1 (at the most). We are not going to do you homework, practical exams. Post the code you have already (as requested by Anders). Ton

Hi Malani, your question is a bit unclear, but I would have a look at the 'Save Instrument' method. Ton

QUOTE (chan0192 @ Dec 23 2008, 07:48 PM) Hi Chan, What is the current state of your code? Do you have something allready. I advise you to look at the shipped examples, try to study them. Ton

Hi Rolf, could you explain what will be the difference between this one (2.4b) and the one that will be published via OpenG.org (2.4?) I assume you actually want to do some testing on VXworks, I think I have one at the office (might be Pharlaps). And you want to fix the Mac bug? Ton

Hi Ben, thanks for your info. Tickling can be started by an asynchronous VI started in the Init instance. If you look at my 'LabVIEW toolbar' example here, I use a similar approach like you, only I used user events for 'click' actions. Ton

QUOTE (Ton @ Dec 22 2008, 01:41 PM) Re:Tickling Yes you read me correctly. Yes a timed loop can be used to do the tickling but then the XControl is dependent on something outside the XControl to work properly. Re: I used a Picture Control for the only FP object. Mouse down/up/move Event triggered similar methods for the object associated with that portion of the screen. The Plug-in interpreted the methods and responded accordingly including sending image update to the Picture so the user could see the knob turn etc. Again this highlight the strength of LVOOP for an app like this. The Instance of the Class Picture knows nothing about the Plug-ins it hosted. It only knows "If the user wiggles over here" that area belongs to this widget so I'll pass it along" and if it gets a screen upate it should update the image in that area. CRELF wrote "That sounds really cool Ben - any chance of seeing a demo?" My app is just a re-architected version of the demo Tomi posted (See here for drawing demo and here for Plug-in ). Special thanks to Tomi by the way! I just built his demo into an exe in order to convince my boss LVOOP was the way to go. Ben
