I think we've got a pretty significant language barrier here, because I don't think it's clear to any of us what the real meat of your question is.

I am sorry,My mistake!I meant binary.

What i want to do is to make a loop that gives me one value each time during the loop.

Then I can take each value,compare with another value and make my graph.

It is correct that if you put code outside the loop, you will only get the values from the loop after all iterations of the loop have completed. If you want to use the values in each loop iteration as soon as they're produced, you must put the code inside the loop.

There are at least two things you may not be aware of, which may help you:

• There is a pair of functions called Boolean Array to Number and Number to Boolean Array that will convert an integer to & from an array of boolean values.
  
• You can display any integer in boolean or hex by right-clicking on it and selecting Display Format....
  

I'm sorry we're not able to be more helpful. It's just really, really unclear what you're after.

I'm just glad I'm not in any of those pictures.

I am so fascinated by all of this. Thank God for teh Intarnets.

Yes, God, I mean you.

I only wish this app was written in LabVIEW, so I could try to envision what kind of block diagram a person who thinks this is a good user interface would come up with.

And yes, there's more where that came from.

Is anyone else gonna take that one, or should I?

I'll take it. 3779 posts and you still haven't gotten it.

This seems like an appropriate place to mention the http://www.boingboing.net/2004/07/27/elizabot-passes-sexc.html' rel='nofollow' target="_blank">horny 18-year-old girl chat bot that made a rather convincing run at Turing a few years ago. (link is safe for work, 2nd-order links may not be).

The idea of this being automated also occurred to me. It's interesting that it struck both Stephen & I the same way.

EDIT: This is delightfully meta.

Maybe I'm being a stickler, but I would have expected the creator of the universe to have better control over the language and the keyboard...

I suspect that it's our flawed human language which is ill-equipped to completely capture the mysteries of God's communication and properly express the nuance of Truth^*. God Himself speaks, and you would question His Almighty Grammar?!

^*Also, amplify the synergies (for you, crelf).

Does anybody have a recommendation for a good presentation remote for controlling PowerPoint/Keynote/etc. presentations? I need one that's Mac-compatible, so Bluetooth, maybe?

And I need it by Tuesday, so I'm looking for something I can get at an ugly, impersonal, overpriced big box store .

Anybody got a favorite?

Are you doing this with hardware, or is it just a programming exercise? The solution will be very different depending on whether you're operating any "real" hardware or whether you're just doing a demonstration that displays things to a front panel window.

Also, have you looked through the intro materials in the LabVIEW Help? They're probably the best introduction to the basic tools available to you.

I am not using the labview for a long time,that's why i have a question.I have already searched at google and at some of my books but i haven't found the solution in my problem.I am trying to create a graph showing the fluctuation of voltage depends on 3 switches.

What have you come up with so far? If you show us what you've got, we can definitely help you figure out what's wrong with it.

What kind of warning do you get when you change a typedef by adding, removing or renaming controls within it?

None, but I can't accidentally modify a typedef by just mistargeting an item in the right-click menu.

Yes, I've always been quite proud of my user number. Thanks for noticing . Note, also, that if you add up the digits you get "2+9" and "9+2" which equals "1111". The prime factorization of 1111 is {11, 101}. All of these numbers are palindromes, too!

If you like palindromes, I have a song for you:

Popping up a dialog and requiring user interaction doesn't seem like too much of an improvement over Michael's Find/Replace trick (and I believe his trick is undoable).

Having it in the context menu would save several clicks over the Find-Replace mambo. That's a huge improvement.

Also, I would prefer having a confirmation dialog of some sort because Relink All Instances is an operation that can potentially change several hundred VIs whose windows I don't have open. I understand why Michael abhors dialogs, but in general an operation that's going to affect hundreds of files I'm not even looking at should both warn me before it does something and give me the chance to back out.

I, for one, welcome our new Supreme Being.

Oh God and Creator, I beseech thee, give us your opinions on String Theory!

Also, have you read this book? How accurate is it?

I'd go for a new context menu item, right below Relink to subVI, called Relink All Instances. It would need to have a confirmation popup of some sort, maybe like Rolf mentioned: "There are 500 instances of this VI in memory. Do you really want to relink all of them? This operation cannot be undone." When selected it could just automagically do a replace, like Michael discovered.

Congrats, Jim! :beer:

Frankly, the honor is so overdue that when I checked Chris's link my first thought was, "Which name is new? Wasn't Jim already a TALM?!" :ninja:

EDIT: crelf fixed his post to make it look like I can't read. Thanks!

Can anyone explain this?

A Picture Control that has been painted transparent has a different Erase First behavior in the context menu.

Regular picture control, dropped right off the palettes:

Note that the Erase First item is enabled, and checked by default.

But, if we use the paintbrush to paint the interior of the Picture Control transparent and then bring up the context menu again:

Note that now Erase First is checked and disabled so it cannot be unchecked.

But there's more. If you try to set the Erase First behavior programmatically, LabVIEW doesn't generate an error and seems to accept the setting, but the change isn't reflected in the context menu:

Attached VI: Download File:post-2992-1228161220.vi

It also appears that, regardless of the behavior shown, a Picture Control that's been painted transparent ignores all programmatic Erase First settings and behaves as though it's set to Always Erase. This, in turn, means that if you set a Picture Control's background to transparent, it will always tend to flicker as you draw more stuff to it, unless you take special precautions (like deferring panel updates).

Why does a transparent-background Picture Control behave differently from a Picture Control with an opaque background?

QUOTE (vultac @ Nov 29 2008, 06:43 PM)

Hi guys, ive been wondering if there is anywhere in labview that i could program something so that the 1st 2bits would stay constant after i apply an addition to the previous set of bits after a for loop everyttime?

for eg.

(starting bit) (first 2 bits doesnt change) (first 2 bit doesnt change)

00000010 -> 00000110 -> 00001110 ???

The tools you need are in the Programming >> Boolean and Programming >> Numeric >> Data Manipulation palettes. The boolean logic functions (AND/OR/XOR/etc.) will all operate bitwise if you pass in U32/I32/etc. data, and there are also shift and rotate functions.

Nothing to say, but congrats! :beer:

QUOTE (jdunham @ Nov 26 2008, 09:15 AM)

why would it need to be recursive? the OS doesn't recurse down those paths. Just test all the paths in the environment variable and you're done.

It's not recursive? Hmmph. I always assumed it was. That does simplify it.

QUOTE

Ya, that's an interesting thing. Turns out the program I'm looking at doing this with shows its "About" dialog if you call it with either no arguments or invalid arguments. So that's delightfully unhelpful . For 99% of the other command-line utilties in the world, that would work.

Vote!

QUOTE (normandinf @ Nov 26 2008, 05:58 AM)

I thought the Windows equivalent "which" function was doing a recursive search too.

It probably is .

I just don't want to implement it myself if there's a better way. However, posting/Googling/yelling/crying haven't yet produced a solution .

QUOTE (normandinf @ Nov 25 2008, 05:05 PM)

There's a function in kernel32.dll to get the list of environment variables. (http://msdn.microsoft.com/en-us/library/ms683188.aspx' rel='nofollow' target="_blank">GetEnvironmentVariableA)

But that only gets me the contents of the PATH environment variable.

I'm talking about something like the following example of which in the OS X Terminal:

[18:58:35]$ which curl/opt/local/bin/curl

It returns the path to the curl binary. If curl isn't in the user's path (for instance, if it's not installed in the system), it returns nothing.

Obviously I could take the results of the VI you posted and list the directories recursively until I've either exhausted everything or found what I'm looking for, but I'm hoping there's a less brute-force solution than that.
