Another opportunity for a new test niche. [connecting the dots] Since Gates announced SPOT a coup0le of years ago, and the core is based on a subset of .NET, and LabVIEW comes with .NET access, and NI is going smaller and smaller, I wonder how long before the announcement comes from NI of a new Toolkit or addition to the FPGA tools that will target the SPOT framework? [/connecting the dots]

I just tried and was able to get the cached pages, but not download any of the samples/code, etc. Makes me wonder what happens to the copyright on all the code that was sent through LTR over the years. Is it lost to the LV community? It occurs to me that it would have been nice, since LTR decided to go out of business/print, that all the code should have been donated to the open community after contacting and receiving okay from the authors.

I suppose the next thing would be to make a quick prototype and then try to communicate between 2 PCs or just substitute the .NET VI wrappers in a simple serial app.

Infrared, heat, which can be motion or image detection. You might add fingerprint recognition. There are sensors for that now.

Sadly, this is still true. Now that NI allows us all to install 3 machines with one LabVIEW 8 license it would be great if theywould allow any mix of platforms as long as you meet the 3+home limit Yes, you can easily recompile. We did it for an astronomy project that used both Windows and Linux. The main problems we ran into were a few font size issues and a couple of cases where we had DLL calls in Windows and SharedLib calls in Linux. It was a minor hassle, but I wouldn't call it real painful. The flexibility we got with Linux-RT was worth it, for that application. YMMV.

Go to NI.com and in DevZone search for Parse Lookup Tableor try here: Parse Lookup Table Cheers :beer:

Giving everyone a linux station will cost, at most, about $200.00 per developer. Either you install Linux in a dual-boot configuration, or you simply buy a removable HD kit plus one spare caddy each. About $25.00 http://www.newegg.com/ProductSort/SubCateg...?SubCategory=43 Look at the Kingwin KF-20-IPF HD rack and the KF-20-IT extra caddy. Actually $15.00, but add shipping. Then you buy an extra HD for each, about $175.00 (I like bigger HDs, you can go smaller). Set you boot drives to be in the caddy. Yes, you can dual boot linux and Windows, but I find the caddy solution is a good/better option for many apps. YMMV. Don't get me wrong, LVRT is a great product, but Linux is an option.

Wink is a great little tool/utility and the price is right!

Yes, for LabVIEW 8. I expect to be doing occasional work for clients who are sticking with 7.x or earlier for some time in the future. Nice to have backwards functionality, even if you have to substitute a work around for newer built ins.

LabVIEW Development Guidelines, Chapter 6 Style LabVIEW Coding Guidelines And if you want a book: A Software Engineering Approach to LabVIEW roughly $70.00 USD with shipping. There are others, but this is available and covers the bases. Why reinvent the wheel here?

Hmmm, yes I agree, if the objective is just to list and select folders... I misunderstood. If you search at MSDN you can find the basic OS DLL calls for various dialog boxes. There are various options as to how the dialogs behave, shouldn't take you long to find the combination to do what you want.

Not a lot of activity on this thread for a while, but I note that the 12/07/05 digest of Info-LabVIEW has a thread going for scrolling trees and other controls. Just in time for me too, as I have a new need for this functionality.

From all of us to one of you: TYFPT !! *Thank you for posting this

CamStudio is a simple and free tool for capturing areas of your desktop to AVI files. It doesn't have a lot of bells and whistles, but the price is right and if your needs are simple: CamStudio at About.com There are also a bunch of utilities of this type on Tucows. Screen capture to video on Tucows :beer:

If you search DevZone at www.ni.com you should find some example VIs already written that will do this.

Depends on how full featured the OS you run the executable in is. NI now sells a toolkit(s) for embedded app development. A few $$$. I've seen several apps written for the PC104 formfactor over the years. When you ask how to proceed, it also depends on what I/O and other functionality you are using. Linux makes it really easy, not to mention cheap, to write shared libraries to access hardware compared to Windows, but Windows has a ton of tools and drivers from their respective hardware companies.

First: TYFPT !!! (Thank You For Posting This) Pronounced like a cartoon character sticking their tongue out, say, Opus from Bloom County... Okay, think about it, it really wasn't that bad, and if you take your Read.vi and cut out the loop, feed in the VI name, you now have a simple subVI that takes in a VI name and returns a menu ref, providing you have added in that little snippet of code to the called VI. Not perfectly elegant, but as hacks go, this is really pretty painless now. Now you have it, and so do we. :worship: It couldn't have been that painful to write.

Under the Menu: Tools > Options In the Options Dialog go to the Miscellanious tab. Check: Use Native Dialogs That should do it for you.

Jim,I did say that it was a real hack. Obviously not suitable for general purpose programming, especially where you might be needing to modify the state machine a lot. It would even be acceptable to me if the tipstrip showed all the values a given CASE frame handled, but it doesn't do that either, nor does the description. Even the popup menu when you are going to select the case uses the elipsis. The only good thing here is that they are all consistent and if we can convince NI to change the behavior, or make it optional, it appears that they might only have to change one small part to have it carry over to all the different displays. At the very least we need the tipstrips. Mike

Someone has done part of your request: Nicola Chiari created a ShutdownLibrary that also does Reboots. It is in LabVIEW 6.1, but can be recompiled into newer versions. Enjoy :thumbup:

Probably the easiest way to get this into LabVIEW use (under Windows at least) is to incorporate your code into ActiveX or .NET then use events from those. LabVIEW now has the ability to hook onto callbacks from them. Search NI DevZone for articles on examples of how to do this.

This is called, "Wizards of Winter" thats the song, and if you google on that phrase you'll find that it is now posted in dozens of places. Very popular. Could this be done in LabVIEW? Using IMAQ vision I don't see why not, if you want to take the time to write a video editing tool in LabVIEW, but you can buy one for $50.00 or use Windows MovieMaker for free on XP.

Norm, I agree, this is needed, has been needed for a while. I first thought about this while trying to make wrappers for an astronomy file format read/write library. The astronomy crowd already had a very good library with about 200 functions in it, DLL or shared lib. We ended up uisng CVI to make the driver tree file, then used that to get LabVIEW to make us the wrappers, but even then it was obvious we all needed a driver-wrapper utility. The problem has been development time. If you have just a list of the functions: void myfunc1(int arg1, string arg2........); int myfunc2(arglist....); then the problem isn't so bad. But most of the time there is a lot more stuff in the header files and making a parser that filters out all the crap and ignores it turned into a pain and I had to stop. We need someone who knows perl or something similar to write up a Parser frontend, then we do the rest in LabVIEW. I'll see if I can't find the code I'd hacked together and dust it off. I'm very busy trying to finish a couple of proposals and find new consuting/integration work right now, so that has to take precedence. Give me a little while.

Well, thats what I get for having 2 monitors and editing video and LV diagrams at the same time. My video editing software is version 7.3 (although, like LV it now has V8 out), so no, there was no LV 7.3.

Thank you.
