"quese -aristos" <- looks like a great username!

or, something with "queso" in it; perhaps Aristos con Queso. (Almost) everybody loves cheese!

That way I could (hopefully) search on "queue" and not get all of AQs posts in the results.

Search for queue -aristos.

This also works, with the added benefit of opening the VI. My problem was in trying to find a method of the BD instead of the VI. I included the Code Capture of the Traverse For References VI to show how I get an array of all my free labels (thanks Darren).

Hmmmm. I wonder if we need to have the NI Unit Test framework work more tightly with NI Requirements Gateway...

We're in the middle of planning our 2010 capital budget and I suggested that we purchase Requirements Gateway licenses, but the idea was shot down without mercy. The IT department shot down another idea to use SVN, but at least they had a reason (we use Telelogic Synergy).

PS - Unit Test? What's a Unit Test? We don't need no stinkin' Unit Tests! (I misread Mr. Mussa's poll as "NO Unit Test Framework" and voted for that. I've since fixed my answer.) That feels like another purchase request that would be shot down. At least there's an alternative.

Hope this helps

It does, thanks.

How can I make a Block Diagram the active window? I'm writing a program that searches a VI for free labels (that indicate test coverage) and I need to get the BD to the front so the Object Highlite is visible. It's working, but I need to manually open the BD and move my interface out of the way.

I'd buy it, in two shakes of a lambs tail.

Hi there,

is it possible to set up a NumCtrl with a "wrap around" [...]?

You can use an Event Structure. If the value changes to 6 set it to 0, if it changes to -1, set it to 5.

This effort is worthy of upgrading to a Premium membership. if only I could figure out how...

im using ms access. thanks.

Do you have the Database Connectivity Toolkit? If not, there are several ADO toolkits available.

I'm asked to do a connection between a microcontroller PIC18f4520 and labview by using a rs232 cable and to get data from the microcontroller to show on labview.

I'm not hip to PIC, but I use Parallax microcontrollers and they have circuits external to the PIC to facilitate the serial communication. Do you need this, and are you confident about your hardware? Otherwise confidence/Jimmy has it right and you're probably closer than you think.

thanks..

can i replace this tool>>>moniter shared variable

please i want complete my work

This reminds me of my Senior year in High School when my Electronics lab partner told me to "hurry up and fix it, I want to get this done."

there is some wrongs.

The first thing I noticed was that the control you're using to stop the while loops is located OUTSIDE of them. That control will be read once before the loops start and the loops will never stop (without aborting execution). It doesn't look like you're very close to being done.

Here's an example that demonstrates using a Notifier to stop parallel loops. You can put your code in these and your VI will stop cleanly.

I was thinking of possible "unhelpful but working" solutions to homework problems.

That would be HILARIOUS!!! Solving HH questions with obfuscated (or Rube Goldberg) code!

I guess we'd have to give them at least one chance to demonstrate a willingness to do the work themselves before posting anything unkind...

Put the mouse down and slide away from the keyobard. We don't want anyone getting hurt! Have you ever tried to clean blood out of a keyboard?

Ben

The blood isn't the issue; bone fragments make it a bigger job than it would otherwise be (just rinsing in a mild H2O2 solution...)

Please, let me know what you think

I think I'd use a dedicated state to update the UI elements based on a cluster of settings passed in the shift register. Route the machine there after updating the cluster in your other states. I got this advice http://forums.jkisoft.com/index.php?showtopic=936' rel='nofollow' target="_blank">here.

No wires! :thumbdown:

I was nearly finished writing a very articulate, eloquent response to the responses to my earlier troll post when I fat-fingered my laptop's 'back' button. Anyway, I'm sorry for writing the way I did but I've been working on a project that was started in TestStand and LabVIEW and I'm not enjoying myself. I did another project in TestStand and felt that it was overkill. I know that my opinion has been influenced by my lack of understanding/expertise with the tool, so I have two more things to say. No more foolishness, I promise.

First, the learning curve to TestStand is very steep. I expect to spend a lot of time learning to use it effectively, but I expect it to make me more effective (once I get over the hump).

Second, I love how easy it is to log test results to a database. I was able to assist a colleague by first installing MySQL and logging there and then again, later, by connecting to the factory SQL Server database with very little effort

Hello all,

I've been asked to evaluate TestStand [...]

I've heard many of the benefits of using TestStand but I still don't like it (the only thing I appreciate about it is that it'll manage User privileges for you). I'm sure that I'll find an application for it that I can't accomplish easily in LabVIEW (like when I need to handle multiple UUTs and share resources among them - that'll happen soon (yeah, right)), but for now I can't get past the feeling that it's just another text-based mess.

I mean, who programs in text anymore? Really...

If you only want to convert to strings I believe you should be able to do so already since the used Python API should actually be able to return string format [...]

You were correct. Thanks.

A post on NI's forum asked:

QUOTE

I want to put a formula node on the front panel of a LabVIEW execution file, so that user can type their own code in the formula node and get their own output. I tried this but it seems only feasible before I build the source code to an execution file.

Is there anyone can help me? I appreciate your help.

I posted a solution using the OpenG Python tools (a few solutions, actually, as I kept playing) but I wonder how I can improve what I finally came up with. I use a Case structure in a For loop to get the data from the Python session, but I've had to put a case for each data type. Is there a way to get this dynamically?

Thanks,

Jim

For some reason after calling one of them, executing and exiting the vi, the main vi doesn't respond anymore to comands.

I'm wondering if your SubVI is really closing. I see your While Loop termination in the 'Achizitie' case so execution should continue in your Main VI, but apparently it isn't. Take Mike's advice and use Execution Highlighting to see what happens after you close the second VI. Perhaps you have another event configured that is stopping the loop. What/how many cases have a True wired to the loop condition terminal?

I was first struck with the Mouse Up event you're acting on; is there any reason you didn't use the Value Change event? That is typically used.

I know there are better ways to do it (like with OpenG tick count if my code has an error in and out)

I'd still be as dumb as a stump if I didn't follow the posts on LAVA. Just yesterday I drew a Flat Sequence structure around a Tick Count (ms) function to time something. Thanks hooovah.
