LabVOOP Design Patterns, v1.0
Norm Kirchner replied to Aristos Queue's topic in Object-Oriented Programming
It seemed appropriate to this thread to mention that the LVx framework is, as pointed out by Tomi, an implementation of the command design pattern. Also, I bought a book that I would recommend regarding this topic "Head First Design Patterns" Very well put together and easy to read. -
Virtual Laboratory using LabVIEW
Norm Kirchner replied to gaby's topic in Remote Control, Monitoring and the Internet
Part of the functionality of the embedded web server, that you said you tried already, IS to allow MULTIPLE connections at once. You may need to purchase remote front panel licenses, but it is definitely possible for multiple people to connect to 1 front panel at the same time -
Map, implemented with classes, for 8.5
Norm Kirchner replied to Aristos Queue's topic in Object-Oriented Programming
Before AQ whips up his reply I wanted to interject a question on the note of variant attributes. If the data stored is of any reasonable size, is there any expectation of in-placeness when extracting, modifying and placing back the attribute? Thanks -
So as my mind was wandering around as it usually does, it occured to me that the creating objects is a bit more involved in G than in text based languages due to wires and icons. It's a great ability to modify these, but sometimes I just don't quite know where to start. And it occured to me that it would be great to have a common wire style guideline to help me determine what kind of object wires should look like what. Sure I could come up w/ my own, but wouldn't it be great if the whole community came up w/ a common consesus on what kind of object wires should look like whatever. example: LVOOP w/ references should use the chain link style wire, and all parents should use a black border, etc... Any ideas? Anyone already have their own they care to share?

When do you use Subroutine priority?
Norm Kirchner replied to Jim Kring's topic in Application Design & Architecture
the rule of thumb that I try to use is "if it is very simple, already always executes relatively quick, has no other interaction w/ other parts of program and could give me speed benefits by utilizing my entire processor." Then I seriously consider changing it to a subroutine. Personally I do not feel comfortable EVER saying skip any part of code that I put in, unless it's a case in a structure. -
In the snow like that all they need to do is pull the sounds from Empire Strikes Back droids communication on Hoth and you've got one eerie similarity.

I'm having issues w/ the board remembering that I've seen a post.... get's kind of annoying when that's the only page you visit. The only thing that has changed on my system is that now i'm using that handy glyph that Yen highlighted that I didn't realize how it worked before. ???

Although you are not using a network license manager, LV still looks occasionally for it's license on the local PC and it goes through NILM->LMGRD->FlexLM processes to do the checking. I used to see this all the time w/ out cause so you are not alone w/ this, but I am on a laptop and technically I do use 2 nic (wireless & docked wired). I have not seen it recently.

are you chastising us for chastizing them. Well HA! I'll report you.... .wait... I've just done it again.... Hope I don't get reported.

quick note, only make 1 post in the forums and not duplicates Also if an input to a VI is an array and you only want to change 1 value, you can always use the build array primitive in the array pallette and it will turn your 1 element into a 1 element array. There are many other points w/ regards to this about how to only change 1 bit, but that will focus around making a task or channel in MAX. Try the build array primitive and then try to work w/ making the DAQ task only change a line rather than a whole port.

QUOTE But it does... the control just needs to have the key focus
-
another easy way to do this is to ensure that the slide has key focus you can do this through setting the property of the control. You can do this at startup or repeatedly throughout the program, or only when the left key is pressed and then you don't need to worry about if they hold the key down because the control will handle this for you.

How to create a tree structure without using the control?
Norm Kirchner replied to Daklu's topic in LabVIEW General
QUOTE (Daklu @ Mar 24 2008, 03:17 PM) Will the data ever be displayed or was your thought to use the tree to only store the data in a hierarchical format? The reason I ask is what is the overhead you're speaking of, because to grab values/properties from the tree is very fast depending on what you're doing, and w/ the Variant based DB that I have integrated, if you're extracting and modifying information and adding information, the only overhead is the usual time associated w/ the variant operations. -

Norm Kirchner replied to Norm Kirchner's topic in LAVA Lounge
I'm glad that you mentioned Google Mike. Although you can setup reminders on Jott along w/ the message, if it is an appointment you're trying to remember, I would strongly recommend setting up a Google Calendar and linking Jott to it. Because of the SMS reminder ability and plain text quick add in GCal, Jott links almost seamlessly in setting up appointments and will parse out the needed parts in your plain text Jott. I could go on, but just check out the links section on jott then go to Google calendar link. -
What kind of data and what kind of communication? It might help the right people know to chime in and offer their names up and good contacts.

I have a VERY hard time remembering things that I say I'm going to do or things I tell others I'll do. Out of sight, out of mind is an understatement for me. I'm one of the biggest scatterbrains around www.Jott.com Here comes the cool part. FREE VOICE TRANSCRIBED NOTES W/ SMS AND E-MAIL REMINDERS through a 1-800 number So lets say you're walking down the hall at work and you think about doing something. You can spend the next 3 minutes trying to make sure you remember and forget the minute someone walks up to you and talks about something else or you simply hit the speed dial number to Jott on your phone (#9 works for me), it goes beep and you leave a voice message and later you go online and you can browse your Jotts. Or if you want you can set a reminder after you make the jott on the phone and you'll get an SMS and an e-mail when the reminder is set for. AND to top it all off, they have links through Jott to other services like Google Calendar and where your transcribed message ends up in a calendar or other service. THIS HAS CHANGED MY LIFE. I am FINALLY remembering things that I'm supposed to be doing. And if you don't believe me, simply look @ the image below. -

How to create a tree structure without using the control?
Norm Kirchner replied to Daklu's topic in LabVIEW General
I've actually recently made some updates to the tree control API (unsubmitted as of yet) that does something great! It now has an integrated variant based database which allows storage of data associated with each element of the tree. The only thing is that it's fully operational but I couldn't in good faith post it because I haven't tested it as well as the rest of the API. The only thing that really I'm concerned of is management of the data as elements are moved/removed/cleared and so on. If I get piinged hard enough I'll try to take some time to get something submitted.
