The LV compiler already does some loop unrolling. That's something you'd never actually see on the diagram, just as you don't see it in C compilers, etc. If we ever had distributed parallelism, where each frame of the loop passed to different computers, that's something that would be displayed to users.

I have seen this where removing a shift register (it was not usefull anymore) sped up (is that proper english)?

the for-loop with a lot (10 x times faster or so). Should have :camera: it. I got the the idea that all cases (or several) were executed at the same moment!!!! But I am a little afraid in trying to reproduce this, because it sounds too good to be true... :laugh:

I need an installer that will remove an existing .exe installation (one .exe and one .ini file) and then install an exe with a different name in a differently named C:\Program Files\AppX directory, and copy the original ini file to the new dir. (I'm supposed to do it in LV 7.1 but 8.2 would be ok.)

Or you could do some start-up check (maybe INI-controlled) that will trigger you app to remove the old program and copy the new one to the right location. Shutdown your app and restart your app...

Maybe best is to use a different named ini file? app-settings.ini or something

If the SubVI is not reentrant, the LabView opens normally.

I think that it was LV 8.2 which introduced seperate FPs for reentrant VIs, which means that the only way is probably to upgrade.

To workaround in 8,

Maybe you can use a .vit (VI template) and open a new VI based on the VIT and use this as the reentrant VI

Just to add more fuel to the fire...

Firefox 2 Released

Download it here.

I am using FF2 for a week or so, the problem is that it is NOT backwards compatible , some of my favourite add-ons were disabled.... One mayor problem is that occasionally I look at orther fora (as in plural of forums) say forums.ni.com, if I download a vi in FF2 it will not give me the option to open it right away (maybe that is a very good security tactic because not everything from over there is save to open)! But on LAVA I can just open everything right away into LV :laugh:

Ton

My favourite add-ons are:

wizz-rss

IE-tab (a new IE-window will open as a IE tab in FF in my case) for my local intranet

Hi Peteski,

what about this:

I love these OpenG thingies more every day!!!

Hey Guys,

I am still wondering what causes can stop a program which front panel state is set to hidden. Because every night around twelve it stops, but keeps running if the front panel is open. Guess I have to ask my system manager what is happening at night.

Eaolson,

What are your stop conditions (could you set a log when a FP close? happens)

Ton

It's a pleasure to see a LAVA member comming forth and contributing tutorial\example type material. Hmm, perhaps we should open up a Scripting category in the Code Repository... :thumbup: . This code Should go there under an "examples" subcategory.

I thought this would be better for the Knowledge Base?

Ton

It seems that the rabbit hole stops here for now.... Anyone found otherwise?

Hi David,

look here

Ton

Is there much of a difference between hiding the application by setting the FP.State property to Hidden and closing the front panel by setting the FP.Open property to False?

If I recall correctly will closing the FP terminate the executable if it is the main VI.

Jesus guys, so tell me, what in the GUI gives you the slightest hint that holding down the mouse would give you this menu. A clever UI trick but not very usefull if only a handfull of people find it.

As I said, maybe I'm not that fast No I thougt to go up to the root palette really fast by holding down the mouse and then

Has anyone out there experience with Visual Source Safe 2005 and LabVIEW? I called Microsoft, but there is no trial software availiable, and I am not willing to spend 600 bucks for a "try". Or even better, has anyone a tip, where I can get a Visual Source Safe 2005 trial?

I use VSS 2005 with LV, but have some issues with them:

• when you loose you netwerk connection the SCC is not available resulting in a lock down of LV
  
• The level of control inside LV is limited (check in/check out)
  
• Sometimes the working folder deep down is wrong and you have broken links inside VI's (that might be a problem that is personal related)
  

I don't know where to get a trial version..

Ton

:thumbup: I never knew about that one - thanks ton!

It took you 1000 posts to learn this? Maybe you are just too quick with the mouse?

Mike,

A devsuite with RT and PDA?

No, to less for the time spend...

But, if you did something like this, what would NI pay to you (if you had it correctly licensed)?

Ton

Sort of an issue of "giving a fish" vs. "teaching how to fish"...

Gary,

if you have opened the right palette, click on the 'up' arrow and hold the mouse down. This will show a drop down menu with the path of the palette:

Ton

heh heh heh Sorry Dan - I don't mean to laugh, but it's an issue that I'm sure all of us have been through at least once. I feel for ya mate - keep your chin up!

I think we all sometimes mess around with INI files we shouldn't

Ton

But what happens, are the first or the last elements removed?

As long as from version 4 (maybe earlier) there is room in the array type descriptor for a fixed size array.

Currently this is set to -1, I wonder what happens when you set this to another negative number

Ton

OK, I get the point

Louis could you describe what kind of failures you mention?

But a more serious issue (which I think is very very serious) is that a convert to U* from a I* doesn't convert the value but typecasts it:

This goes for U8,U16,U32,U64

It shows no coercion dots, this issue will be quite hard to deal with...

Ton

yes, but shouldn't that feature allready exist in the BASE Package, due it's importance? What do others think about that?

I agree, it could be next to the "Show buffer allocations.." tool.

I don't agree, this issue (coercion dots) are more something for the advanced users, I agree that you should try to minimize them, but I don't take great effort to remove them.

Ton

I have some issues with using drag and drop on XControls. I even tracked it down to the point where I found out that events for XControls don't exist, so not only drag enter doesn't occur, even mouse enter isn't triggered... :headbang:

I have read this topic but there drag and drop is applied on parts of the xcontrol.

I have the feeling that I should register and unregister for the events in the Init and Uninit abilities but am not sure.

Can someone prove me wrong on this subject?

Ton

your're right. I first thought you could find coercion dots, if you enable "Show warnings in error list dialog by default", but the are not mentioned. Maybe that would be an other feature to request? "Find Coercion dots"?

VI analyzer?

Here is some code is scratched, it uses for VI Analyzer, and allows you to browse to the coercion dots!

Beware, you need VI Analyzer to run this!

Hi i2dx,

It appears that a shared variable only holds the flattened data and not the type-def control...

See here

i don't know what is wrong here , when i want to change the values exp. frequency ...it doesn't change the sound .

Hi Kameran,

use 'execution high lighting' and see what is wrong, then do a search on Data-Flow programming.

Ton

Has anyone a clue for me?

-> the workaround would simple be to use 2 tasks ... thus there is no "real" problem ...

Hi i2dx,

I think the silence has warned you already but it is not possible. When starting a task you already have to set its main properties and directions. So go with two tasks.

Everyone is *somehow* a little bit lazy - except me, I am lazy like a bone - and I can in a way understand, that someone, who was not part of the challenge does not feel like looking through all submissions and reviewing it. Maybe, next time, we should pass on the public vote, and vote in the CCC instead?

Yep we're lazy, but I found the criteria somewhat difficult to test. You had to carefully read all related posts to find out what the code was supposed to return and the different implementations all had there side effects in the output. So I found it quite hard to 'judge' the entries. And the judging scheme was maybe a little overkill.

But I felt like I had to give something back (I know feedback is great) for these efforts!

What do you mean by public vote? I assume CCC is the message on the homepage.
