I have been wondering if anyone has tried developing LabVIEW applications using a dual monitor setup

When I work on one screen only, I usually smash my window on the side of the screen while I'm trying to drag it to the other screen.

If your are afraid of increasing your productivity, you can open LAVA on the 2nd screen then increase your ability with the same productivity.

Norm,

Congratulations and welcome to the Dark Side. Kool-Aid is complimentary.

I hear we'll be quasi colleagues. I lead the Industrial and Embedded Control group corresponding to your RF group.

Hello

I am working on a DSC project and am having trouble to find a way to programatically change the citadel logging path of a shared variables libraray.

The application has to run as an Exe. So using the Project properties won't be a solution I guess.

I hope someone can help me on this.

Thanks

Dermot

After taking a quick glance at some of my code it looks like...

1) Stop logging

2) Use "Create Database.vi" to specify where the data should be stored.

3) Re-start logging.

I have been wondering if anyone has tried developing LabVIEW applications using a dual monitor setup, 1 monitor dedicated to the front panel and the second monitor dedicated to the block diagram. I have not tried this myself but have wondered whether is would increase(or possibly decrease) productivity while coding and debugging.

I use a dual monitor set-up and I love it for development. Ww have only dipped our foot in the water using dual monitors in an app. THis get very complicated since the user can use different screens resolutions on each, and the orientation of the monitors can also manipulated. That can amount to a bunch of conditions that have to be handled.

Related aside...

With the hire of Norm, NI has picked-up their FIRST Certified LabVIEW Architect (with a bonus of their first CTSA).

Or does he have to leave is credentials at the door along side of his avatar?

It will be in the RF group and I am getting more excited about it by the day.

More will be revealed in weeks to come, but actually as I will be away from home and family in Austin most of the week to start, so my evenings will be free to contribute to the community.... or so I tell myself now!

So not a Direct LabVIEW job (however I have the feeling not at NI is very far away from LabVIEW).

About those evenings, I sometime have that illusion.

In responce to a question about the SubVI Fixer I found http://forums.lavag.org/-t12460.html&view=findpost&p=54671' target="_blank">here I created a Jing video. I hope this clears up some of the confusion.

More videos to come.

Verry nice Video/Tool! :worship:

The message means that Labview couldnt load the Frontpanel of the VI. Probally because the build proces has removed them (as it does for almost all VIs).

Go to your project build settings (> LV8.0) change the front panel options.

In your build specification goto "Source File Settings" -> Select the correct VI -> Deselect "User default save settings" -> deselect "remove font panel"

Dear All,

My name is Dennis aka "bulletman". I'm a chemical engineer and at this moment

A chemical engineer called 'bulletman' oh-oh (and you're from the Netherlands, should I worry?)

I would try to get some VIs for these instruments, so you have directly all the commands you need.

Thanks for the insight. I though it was C but even if it's Visual Basic it doesn't help me much, I am not an expert in programming. I can understand LabView but not C or Visual Basic. So any help would be great.

I recommend working through the code line by line. There's a alot of overhead in there, so the actual code is not that much. Use Google and online pages for specific information on VB functions.

e.g. DIM is simply a declaration/allocation of a variable that will be used later in the code.

Begin and End mark a specifc section of code.

VB does use objects with their own properties and methods. For example dlg is declared as a UserDialog object.

Dim dlg As UserDialog

Therefore you will see calls to the properties and method of that object. (' marks a comment line)

' set defaults for dialogdlg.probe_name="probe"'dlg.distance = "60."dlg.phase_min = "0."dlg.phase_max = "-699.5"dlg.fmax="25.00"dlg.probe_name_pec = "probe"dlg.modfile ="3_hexa_structure_PEC"dlg.fmin = "0"

You can also pass an object to another function.

'MsgBox datafileDialog dlg

As you get going, post specific questions here.

There is a framework allready shipped with LabVIEW that does exactly what you describe:

LabVIEW x.x\Resources\Dialog\PreferencesDialog.

It is used by the LabVIEW options dialog and allows you to create custom dialog pages.

It seems like the tool tries to balance things out. If I delete the code below the structures then they become small when cleaned up again. It seems to expand the case structures to the width of the code below them.

It likes vertical alignment a little to much, the VIs are aligned with the for loop and the enum and unbundle are aligned with the bundle function.

QUOTE (Donald @ Nov 21 2008, 12:50 PM)

Ditto that.

Another point, don't quote full messages (esp. with images).

It is abandoned by NI in LabVIEW 7.1 I think, and I assume you found it through the OpenG Error Library.

QUOTE (jives @ Nov 20 2008, 09:04 PM)

Hello!

Is there any way to automatically disable or enable specific LV code when building an application? Maybe with a conditional disable structure, or something like that.

This would come in very handy, for example when using a relative path which changes when running code as an application or in the LV development environment. Or one could hide debug output which is useful in the LV environment, but not in a standalone application.

Any help is greatly appreciated!

For this specific thing I would advice like normandinf has done.

However it would be very usefull if we could set a specific 'Conditional disable' value for a specific build.

It can currently be achieved through scripting (Sorry I can't find the code right now).

Well I did find them.

It figures. Every time I reinvent the wheel, either NI publishes the same thing a little later, or I discover it in OpenG or something.

Usually a lot more robust & versatile than my version.

Ditto that!

I developed an architecture that would allow arbitrary data paths between VI to allow customers to compose a system from building blocks that I provided. I spent weeks getting it all to work correctly, in BridgeVIEW 2.1 (LV 5.1). Before the ink was dry on the paper NI released LV 6.0 that feature control references and completely invalidated all of my work. :headbang: Funny, but actually threw away the disks with backups of that code and enjoyed doing it. :thumbup:

Sometimes you are better off being the second person with the idea.*

While loading in Yorktown (USS Detroit AOE-4 Amunition Oiler circa 1978) the guys dropped one of those bombs between the ship and the dock. We thought is was a big deal but it had happened so often the dock workers didn't think twice.

Orko,

The classic graph is still not what what I'm looking for. I've found an example VI. See the attachment.

This example has no border at all around the graph. The classic graph uses a flat panel border instead of a raised panel. But it still has a border.

thanks!

Reinforcing the previous...

You can customize the graph can be customized using the control editor.

You can paint the backround transparent to get rid of the frame.

You could also replace most of the parts with an image of your own choosing. Try out the control editor and let us know where you get stuck.

Getting paid to watch LV boot is generally not a problem unless....

You are standing in the center of a semi-circle of people watching you and you have to come up with a speach to distract them while its happening.

A twist to a Slashdot story.

But then again I do get paid while getting coffee and discussing the latest computer technology...

Lawyers.... Welcome to a tech company. (My 'booting time' 10 minutes, for booting, logging in, outlook, firefox, LabVIEW (twice sometimes)).

The bottom line is, during booting of your workplace you should get a cup of coffee (or two).

You can use the AVI tools from the Vision Module pallete

You can find them in: "Vision and Motion\Vision UtilitysFiles\AVI"

You can find more on settings up a stream in this post
