But that becomes an issue if the cluster was a typedef since the defualt value of typedef'd constants will not retain their default if the typedef is editied.

Or you've started using string constants on the diagram for documentation.

Just popped into my head....

Durring the very first LabVIEW Coding Challenge (bit banging?) I beleive it was Jim that posted after we saw the general trend that the speed of the VI approximately follows the size on disk (smaller VI smaller run time) that a VI with no comments will run faster than a VI with comments. I did a quick check at that time and was suprised it was true! I wonder if that is still true...

I guess I will just have to test it huh?

Yes, it's saying "this section of the code needs coments and/or rewriting"

[OT]

I taught myself to code in C prior to taking a college course in same.

After submitting my first project and anxiously awaitng feedback I was disappointed that the only comments the T/A had about my code was;

"Too many comments! It is hard to find the code." :headbang:

I have yet to see "self-documenting code" that revealed the "big picture".

It could be worse! The customer could have sumbitted the following code to find array size.

I reacted the same way when I saw someone wire an enum to a format into string. I thought it was great but everyone else said "You didn't know that?"

I think this is not our short-coming but rather due to the sparse upgrade notes. I religeously read every one of these cover to cover and still I miss stuff.

WE really need EXHAUSTIVE upgrade notes!

Ok, Maybe this would be better. I am attaching 2 vi's. From vi1 I would like to get and set the string values in vi2's ring.AaronUpdate, By using the front panel and controls reference I can do value signaling to the other vi. But it does not seem I have access to all properties just some default properties. For example I do not see the strings[] property for this control using this method.Aaron

Add ing dsaunders reply...

You have mentioned the invoke nodes but only alluded to the property nodes.

The propertyies you are after are only exposed for cirtain control types. To get at those properties you need to make sure the control reference you are using is of the approriate type. The "To more Specific" node will help with that.

See http://forums.ni.com/ni/board/message?board.id=170&message.id=267659' target="_blank">this Nugget where I offered some ideas on how to handle control refences.

Ben

QUOTE(Aaron @ Sep 11 2007, 03:54 PM)

Sure,

Lets say I have a ring control in one vi and I want to change the text in that ring or enum control from another. When I use the set or get control method, I would only get or set the index as that control is a number. I would like to update the text it displays which is a property of the control. Another example is if I have a boolean control in one vi I can get and set its value from another but that will not trigger an event case. I would have to use the property value signal. I need to know if there is a want to set the properties of a control instead of setting its value from another vi.

Aaron

The ring is easy, just use the "Strings" property to write a new array of strings.

The enum is another story. the strings associated with an enum are imbedded in the data type so they can not be changed at run time.

I am recovering from my first reply?

QUOTE(Aaron @ Sep 11 2007, 03:25 PM)

Hello All,

I am using LabView 8.2 and am using the method control val. get and set a lot. This works great for getting and setting values of controls and indicators in other vi's. I was wondering if anyone knew a similar way to get and set properties of a control or indicator. Specifically I am wanting to trigger and event case in another vi (value signaling) as well as setting the string values in a ring control.

Any help would be appreciated.

Thanks.

Hi Aaron,

Could you elaborate on what you have tried and exactly what you want. It just sounds like you have answered your own question.

QUOTE(NormKirchner @ Sep 7 2007, 05:46 PM)

One thing to add on, is that if you only show a subset of a very large list sometimes you don't want to update the entire data set as you scroll.

Here is an alternative option that I have seen in some software packages.

Instead of updating the table as you scroll, have a hovering tip strip or something of the like, that is linked to a column and displays what would be the topmost item if you stopped scrolling at that point.

Sometimes row number is enough, sometimes something else makes more sense.

Now your talking!

Lets see what I can figure out this week-end.

2. 8.5 is still XControl Bugfree (one month after release )
   
3. XControl will force you to think event driven
   
4. I like them

I was going to say the same thing. Use Array subset and only show a table on the screen as big as necessary.

As far as the XControl; that might be a nice idea. I'm gonna play with an idea and see what I get...

My customers' customers have auditors to keep happy.

I have been putting off the Xcontrol learning curve until I needed it.

It just may be time.

Ben

I have run into this situation more than once and its time to gather up ideas! When attempting to transfer large data -set to a table, we are seeing delay times of from 3 to 6 seconds depending on what machine we run our benchmarks. The data set can be 250K lines and can be as large as 30Meg on disk! We have issolated the performance issue to ONLY the time required to update the table. Using the technique to defer FP updates, hide table, update table, show table, undefer updates has improved performance. So.... I am toying with writing my own Xcontrol but before I do, I'm looking for other ideas and suggestions. So what do YOU think? Ben Cross posted on NI at

http://forums.ni.com/ni/board/message?boar...2&jump=true

I agree with the previous posts that we need an example to be helpful.

Lacking that, i'll speculate.

I have seen LV hang if a reference is closed and in a parallel thread the now closed ref is used.

So check your ref closing order and/or check the validity of the ref before using it.

Like I said, just speculation.
