I THINK some countries have a requirement that the domain must be hosted in country. Example YOURDOMAIN.co.th (Thailand domain) must resolve to a server located within the borders of Thailand. Otherwise, they can't enforce laws (porn, political, etc). Don't know about the Virgin Islands. How about a domain name like "openg.vi" ?

Anyone ever consider registering a Virgin Islands domain name? ( LabVIEW.VI )?!

Unbundling is used for the Cluster data type. If you are trying to select a specific row or column of your 2D array, then you want to use the "Index Array" function in the Array pallet.

The displayed value includes a character suffix that indicates magnitude; I believe 'p' indicates Positional. http://en.wikipedia.org/wiki/Positional_notation

I agree. It doesn't have to be a blast from a shotgun with both barrels, though. I recently demonstrated the fact that you can expand the Index Array function to someone. He had 12 discreet Index Array functions connected to the same array, with one index input to each. They were indexing elements 0-11. I showed him a "trick" and he nearly fell out of his chair. This is someone who has been programming in LabVIEW for 6 years. He's also fond of globals and locals and sequences that nested 5 and six deep ; he blows up when he can't create a sequence local in my code to move data around. I feel like I've got a good handle on all the features/functions of LaBVIEW (5 years+ I just completed the Intermediate I & II classes) and now need to think at a higher level. Many LabVIEW users are just that; users. If you need to create sequence, then a sequence is what you must use! Sort of like an apprentice tradesman; if the only tool you have is a hammer, then everything looks like a nail!

:thumbdown: Well, timed loops are limited to 1 msec resolution when running under windows. You can select 1 MHz clock only with RT; this won't work because I need the DLL. Still thinking....

I will have three A/D channels generating single WORD data running at 1200 Hz each. These will not be synchronized. The channels are enabled and disabled manually, this is a monitoring function I may need to switch hardware and DLL at some pint (this is a VME Single Board Computer), but the alternate DLL offers the same functionality (pointer to a ISH routine). I really don't want to write a wrapper DLL. I might be able to poll using timed loops, I'm evaluating this now...

I have a DLL that monitors hardware. When an defined interrupt occurs, the DLL calls an interrupt handler by way of a pointer to the handler. I need to handle this from LabVIEW. Below is the API documentation for the function. The vmeConnectLM() hooks an interrupt handler when a location monitor is signaled (interrupt occurred). ULONG vmeConnectLM( BYTE LMNumber, // LM number 0-3. ULONG PtrToHandler. // Handler address for the LM INT. ); Parameters LMNumber - The LM number range of 0-3. PtrToHandler - Pointer to a handler to be called when the INT occurs. Return Values Zero, if successful; otherwise an Error Code. Remarks A vmeAcquireInt() API call must be performed before any interrupt can be enabled or disabled. The handler suppose is to be declared as typedef void (*FUNC)(ULONG). If this command is successful, the Location Monitor interrupt specified by LMNumber will automatically be enabled. The parameter passed into the handler will be the LMNumber. How/what can I associate to this DLL function?

If you're just trying to understand LabVIEW, you might check out http://www.iit.edu/~labview/Dummies.html This will help guide you through things like the front panel, block diagram, etc. Good luck!

Well, after reading the comp.lang.labview threads a bit closer, then action engine is really just a "functional global". I've ONLY been using LabVIEW since 5.1, and never been exposed to the LV2 or functional global concept. I understood the concept, but the term "action engine" bothered me. The answer (for me) is here: http://forums.lavausergroup.org/index.php?showtopic=273

I'm involved in a new project where I will be using templates. These templates make use of sub-vis referred to as Action Engines. I've searched various LabVIEW materials, Google and (most importantly) the LAVA Forums. I can't find any references to an Action Engine implementation. It appears that these action engines are passed references to front panel vis and contain uninitialized shift registers. the Actions are enumerated, and current states are returned as outputs. I understand how they work, but where does this term Action Engine com from? I did see a couple of posts on comp.lang.labview regarding action engines.
