What do you mean?

You can insert a single column if multiple columns have been defined. the others just get populated with blanks (unless you have defined a field as NOT NULL)

[...]

Can you elaborate?

Never mind; I was doing it wrong. Thanks for the snippet.

I don't see that polymorphic Insert VI in the palettes. What am I doing wrong?

I've another release almost ready so if you want any additional features [...]

Partial INSERTs would be nice.

Anyone actually using this? (apart from me )

I'm using it and I'm loving it .

Any chance you could post that vi in LabView 8.0 format? The LV 8.2 icons don't look like the 8.0 ones...

Untitled 7.vi

[edit]

Jim didn't post a VI, but a VI Snippet. The 8.2 (and 2009 & 2010) icon should look the same as 8.0.

I know how to read a file and extract individual initialization parameters from it. So initializing each button from a numeric, and outputting the selected value is all I need.

You won't be able to change the control labels at run-time, so you'll have to make the captions visible and act on them.

I imagine the count by your avatar is "posts ever" and in your profile it is "posts now" - the difference comes from posts having been deleted.

I don't know about that. My profile says I have 505 (before this post) and my avatar says 509. Both are above the 500 posts implied in "The 500 club". I wonder what I have to do to get into the club.

You're complaining?

No, just curious about a behavior that isn't as obvious as it seems.

What do you think I should say?

I don't know. Is there an anomaly in my account?

Who did you tick off this time?

Who did I tick off last time?

How many posts do I need to have my status change from "Very Active" to "The 500 Club"? (I ask because I have > 500 posts.)

Nice!

Any chance that it could work for a URL (Text Decoration)? That's what Firefox gives when dragging a PNG into LabVIEW.

I just found this Quick-Drop plugin that SimonH wrote to do this. It includes some VIs with locked Block Diagrams , but it's useful.

How about this?

[...] one advantage MSAccess had over other solutions was that it had a pretty easy ui that allowed users to query data. Do the other solutions offered have good data viewers available?

We use Access with tables linked to a MS SQL Server DB.

This exercise gave me the opportunity to find this TestStand patch that fixed TestStand crashing whenever I tried to use my new VI. I probably ignored a message about it during installation.

Here are two ADO DB toolkits that might give you a place to start.

Thank you. This is what I came up with.

I have a "sandbox" sequence that I use to test my products and develop new tests; it contains all of the sequences that I use for production as well as utility sequences and whatever is in development. I currently use it by skipping every step except the ones I'm working on, but I'd like to generate a list of steps at the beginning of the execution that will allow me to select which steps to run. I figure on making a boolean array and using Preconditions to decide whether or not to run a step. I've written something similar, but it depends on a static list of steps. I want something to dynamically adapt to the ever-changing sandbox sequence.

How can I get a list of steps from a VI called at the beginning of the sequence? I've looked at the OI examples and nothing jumps out at me.

Thanks

It's been a long time since I worked with this, and I didn't have the correct hardware then so I don't have experience with it, but I remember something about some NI hardware being able do do something like this. How's that for concrete help?

The feature of the hardware is called Digital Change Detection, and it eliminates the need to poll your input lines and this KB sounds like what I vaguely remember.

It might be worth considering the schema TestStand uses. It may be a dangerous guess, but I'm guessing that they've put a fair amount of though into normalizing test data. It looks sound to me.

II wouldn't charge more.

[...]

I'd just escalate the time-scale to account for the "learning curve" and "recoding".

That sounds like you would charge more. Not as a penalty for foul-smelling code, but because you're being realistic in that you'd have to include the learning curve or the time to rewrite it.

My take on the question was that Ben was asking was whether it would be ethical to charge above your standard rate to extend a particularly odoriferous project (after accounting for the things you mentioned) simply because the work involved is so distasteful?

Is it ethical to charge a premium to work on bad code?

Yes, unless it's your [company's] code!

I don't think the reason for charging a premium, or even that a premium is involved, is important. It might, however, come up in the discussion after the customer receives your quote.

As far as the problem in your original VI, you're using Shift Registers with the Match Regular Expression node incorrectly. You can't use the Offset After Match if you're only going to search what was found before and after the previous match. Savvy?

For the record, /<(.*?)>/ is considered a fairly "bad" regular expression. You should work with something more like /<[^>]+>/. A cookie to whoever can explain why that's better

Yours will not miss nested tags line break characters. If the tag spans multiple lines the "bad" regular expression will fail.

Thanks for advice !

But regexp have problem...

What's the problem? What should the output be?

How about this?

I can't do it for you, but there are threads on NI's forum dedicated to this: Upconverts and Downconverts. Folks there wait all day for this kind of opportunity.

Hi all,

is there a way to create a custom property node in LabVIEW, and append some custom properties to it? These could be simple values or another property node of the same type. Sort of like the XML DOM property nodes.

Thanks in advance, Mike

You can access a LVOOP class data with property nodes (in LV2010).
