Justin, Is your call to WaitForSinglObject reentrant? http://forums.lavag.org/index.php?act=attach&type=post&id=6179 PJM

LabVIEW support WMF and EMF too(I think). Just drag and drop them on your FP. You could also convert your svg to WMF. Note: these image types are scalable. PJM

Eugen, Please, look at the online documentation about Checking the Network for Available Packages. Also, you might want to enable VIPM to automatically do that for you (Check for Pacakge Update on Startup). Thank you PJM

QUOTE(Eugen Graf @ Jun 14 2007, 09:35 AM) Please upgrade to the latest (by doing a check network for package update in VIPM). Version 1.6 was not working with LV 8.x. PJM

Eugen, Can you check in VIPM if you have the latest package installed (1.7-2) ? http://forums.lavag.org/index.php?act=attach&type=post&id=6096 PJM

QUOTE(Eugen Graf @ Jun 13 2007, 12:40 AM) Eugen, 1) Bird's Eye View The Bird's Eye View utility is similar to NI navigation window. One of the differences is that it also work with older LV version (from 6.0 and up). Once you launch it you should see the window below. Click on the Upper Left gliph to display the full window which has the configuration settings. http://forums.lavag.org/index.php?act=attach&type=post&id=6080 Once there click on the question mark button to display the help about the different options. http://forums.lavag.org/index.php?act=attach&type=post&id=6081 2) dictionnary Drop a VI from the palette and look at the help window. click on the detailed help link. http://forums.lavag.org/index.php?act=attach&type=post&id=6082 A detailed help page will open in your web browser.

QUOTE(Ben @ Jun 12 2007, 08:32 AM) Doing alpha blending in a picture control work very well. This could require quite a bit of work if you want to write reusable VIs and keep it efficient. As a side not, the "Read PNG File.vi" return data with the aplha blending information (ignore the threshold parameter as I believe it is only use to calculate the mask) in the form of ARGB (if I remember right). This mean that you can create very decent effect&UI components that does support alpha blending by combining 24-bit PNG images with existing LabVIEW controls (all in a picture control). PJM

Go for it. PJM

QUOTE(rolfk @ Jun 7 2007, 11:26 PM) The "funny" thing, is that all LV native window (read here: not build in G such as Error List, Profiler...) that can be resized express the expected behavior (Fit as you drag)...' I also have tried to use the resize panel event, and while this work, this does not look as good as doing it natively. There is alway a small delay and your control size end up lagging behind and in my opinion this too does not look good. PJM

QUOTE(Ben @ Jun 6 2007, 06:41 AM) Ben, I was working on pretty much something identical to what you described 3-4 years ago (there is a reference about this in this thread). My goal was to be able to extend the behavior of clicked palette icons. For example you could execute code when clicking an icon. The palette per say was made with a 2D array of picture control. The array was transparent, the picture were transparent too. The main VI was a "vit". It was instantiated as needed for sub palette. The palette definition was an ini file. http://forums.lavag.org/index.php?act=attach&type=post&id=6046 I never got to finish this because of lack of time and also because I think my design was somewhat flawed. But the 2D array of picture control work like a charm. PJM

QUOTE(orko @ May 24 2007, 10:34 AM) The "Initializing Plugins" step take as long (~6s) as the "Converting toolkits" for me. PJM

Well there is an easy work around: - Enable you control - Update value - Disable control You might even benefit from using deferring the panel update (this might hide the fact that you are enabling your control briefly) PJM

Here are my Stats (my laptop is a about a year old or so ant it is a Dell Inspiron 9400 with a Core Duo T2400 1.83GHz and 2.0 Gb of RAM): A couple of remarks: 1) Sometime after working on LV 8.2.1 for a while and restarting it up, start time is back up in the 40 ish seconds. 2) What did improve launch time a lot for me is frequent background defragmentations. I use a deframgmenter that once a week do a deep defragmentation that put the most used application on the fastest access location of the HD (or something like that). This make a very signifiant difference. As you can see in my stat I dont use LV 7.1 much anymore and its start time is pretty slow now. 3) In my book, ~40s for the first launch of LabVIEW 8.2.1 is still too slow. LabVIEW is definitively the slowest application to start on my pc (and it has been for quite some time now)... A first launch time in the 10-15s would be nice

As far as I know, you can't. You have to delete the svn folder after you add the folder (from the project tree). Also, if your folder change on disk you have to repeat the process (delete folder from tree view, add it again, remove svn entry). This is quite painfull. PJM

QUOTE(proja @ May 21 2007, 05:46 AM) Then use the code screenshot that I made and make sure you pull the wire out of the 8-bit pixmap output from the "unflatten pixmap.vi". Then, the result of the indexing of the 8-bit pixmap (for x and y) is not the color but the index of the color in the lookup table. You just have to index the color table with this value. PJM

I am not sure as to how your screenshot relate to your initial question, but this might help you. http://forums.lavag.org/index.php?act=attach&type=post&id=5907 Note: The image has to be 24-bit depth for the attached code snipset to work. Using color table is a bit more complicated. PJM

QUOTE(BOBILLIER @ May 14 2007, 06:57 AM) Look at the attached example from J.P Drolet.

This is really neat :thumbup: PJM

I don't think it has anything to do with large data set. I was just creating a cluster (very simple) when LV 8.2.1 crashed with the same error. http://forums.lavag.org/index.php?act=attach&type=post&id=5736 Note: The cluster was not a type def yet.

Kevin, One common way to handle these refnums (Daq Task, VISA ...) is to coerce them to string in your data structure prior to attemp to write them to disk. The read sring automatically coerce back to the refnum when read back. See image below. http://forums.lavag.org/index.php?act=attach&type=post&id=5711 PJM

QUOTE(James_SGP @ Apr 24 2007, 05:51 PM) I sort of remember having a somewhat similar issue with newport stages (I dont know if this was the same model though). If I recall properly, when getting close to a limit switch at a speed moderatly fast, the stage would not a accept any more commands. My workaround was to find out what was the higher speed I could use that would not generate this issue. So you can try homing at a lower speed and see if this help. PJM
