All the tests get added to a 'regression test suite' which we run weekly to verify that nothing has broken.

Hi Mike

Are you able to elaborate on your test suite - did you get this to run automated?

I see NI is beta testing unit tests for VIs, looks really good.

Hi all,

are there any possibilities to bind LabVIEW RT Software to a specific RT system (a NI-RIO rack)? We'd like to prevent our customers from using our software unlicensed by simply copying it to new NI-RIO racks. I'm thinking about something similar to the Volume Serial Number that can be accessed on Windows systems via kernel32.dll.

BTW (slightly related): I can't find the file "generateComputerID.exe" (mentioned on http://forums.ni.com/ni/board/message?boar...hread.id=88461) on my system (8.2). Perhaps a version issue?

Thanks in advance,

pro

Hi P

See here for an example that may help

At this moment I'm not sure which kind of hardware I need for my purpose.

Here's a http://www.ni.com/serial/' target="_blank">start for NI serial hardware

Which ever hardware platform you choose, from your current spec you will need at least serial 17 ports.

I was thinking that it might have something to do with subpanels, but it did not seem to look the same, and seems somewhat complex to pass the data set on the page to the main UI, while allowing the main ui to handle events when the person is editing the settings. (I know that you can use the get controls, set controls methods, but thought there might be a cleaner option)

I suppose I could use a tab control as well, but it just didnt look as clean as I wanted.

I'm with Andrey on this one - I don't like use the tab control as a type def.

I use the plugin architecture for most GUIs I create, as it is a flexible, scalable design.

But I don't think it hard at all to pass data.

I dynamically register all universal controls (hosted by the Main UI - e.g. tree control) to an interface that the plugin vis can access

Each plugin should handle its own data and have its own UI (no need to pass data to the Main UI)

Each screen's data is an object(s).

Each other screen can access another screens data through an interface if needed

Is it possible to use a latching mechanical action front panel switch, and have the switch correctly reset, when it is used in more than one event case?

Any help would be appreciated.

Regards,

GraemeJ

If you are using the Mechanical Property "latch" the you can not use a local variable or the write to it's value property.

Using an event structure with the boolean placed in the loop is used to refresh the button when a value change occurs.

But some more info would help...

Yer, you will definitely need to look at the Database Toolkit, as it is needed.

I have used it to talk between LV and MS Access, and it works great.

Hi,

I am trying to create a steering wheel from a knob but I still not have any luck. I did make the value from 0 to 360 and the value is spreaded around the circle already. But I have problem with the moving part of the control. The only moving part is the needle but looks like I cannot replace it. Do you have any suggestion for this one? This part is really important with the GUI of my project.

I highly appreciate your helps.

A knob does not have a needle, (wrt to controls) a dial has a needle.

I would have thought a knob would work, i just tried it as a steering wheel and it kinda reminds me of a 2D virtual suicide spinner knob

Aside: I know a lot of LabVIEW programmers that shy away from VI Logger and Signal Express (and TestStand for that matter) because they think that they can develop their own utilities more quickly and with more appropriate features from scratch in LabVIEW. My answer - that *may* be true, but work to meet the requirements of the project that you're working on (use the right tool for the job )

Yes I was quite surprised when I found out that you can write VI plugins for SignalExpress.

So it does have a place in application development.

A) 10 V signal with 0-5 V ADC range: Signal is from 0 to 10V, ADC is from 0 to 5V, so a gain of 0.5 is appropriate.

B) 5 V signal with 0-10 V ADC range: Signal is 0 to 5V, ADC is from 0 to 10V, so a gain of 2 is appropriate.

C) 10 V signal, with 0-10 V ADC range: Signal is from 0 to 10V, ADC is from 0 to 10V, they match so no gain required.

D) 1 V signal with 0-10 V ADC range: Signal is from 0 to 1V, ADC is from 0 to 10V, so a gain of 10 is appropriate.

Ahh.. now i understand the reason behind the question!. I will withdraw my previous lame attempt

I have another one:

All of the following are components of an error cluster, EXCEPT:

A Status

B Code

C Source

D All of the above are Error Cluster components.

I have no idea which one NI wants to EXCEPT here???

To me they are the three components of an error cluster. Arent they?

Yes the answer is D, Status, Code & Source are all components of the Error Cluster.

Hi ,

I am using Labview for 2 month. I want to measure the temperature daily basis (reading in every hour) then i want to write it in a file (which can be use in Excel) after 24 hours the file will close and new file will open to record the data.

I am using a thermocouple. i can acquire data from that thermocouple but the rest work need your help. My intention is to take data in every hour and write it in the file.

please help me. thanks in advance

Kirit

Here is a thread that might help you get moving with some basic DAQmx and write to file in it.

Once you can do the above you are probably going to need look at design patterns so you can implement a GUI and the timer etc..

I did not know NI were still selling this cause I thought Signal Express was its successor.

(It is the last disk, all the way at the back in the Dev Suite )

Does anyone have a preference over one or the other?

OK - thread officially hijacked. I started drinking it at uni too (UTS) because no one else in my dorm would drink it, so it was safe in the common fridge Thankfully I've found similar brews here in the US: Shiner Bock when at NI-Week in Austin and Motorcity Brewing Works Nut Brown when at home in Detroit.

Haven't seen those around here but...

I can't stop raving about Weihenstephan.

The Tradition and the Dunkel are great dark beers.

The bar chick told me that you can get both Tooheys Old and Extra Dry on tap all over Melbourne now - it's good to see that Victorians are starting to come to their senses...

Oooo I used to drink Tooheys Old on tap at Uni and always got strange looks from everyone... they were too young to appreciate the quality of ye dark ale.

So I will drink to that :beer:

Hi!

I want to have an event case triggered by a button click (via Value Change) and a menu item selection. I selected Menu Selection (User) to handle the menu selection and used Get Menu Selection to check the menu item selected. The event case is indeed triggered by Value Change and Menu Selection (User) when I ran it but the item tag and item path are both empty. The Get Menu Selection is wired to Current VI's menubar.

Any ideas?

It is best to handle RTM selections like this when using event structure:

From a LV development standpoint I found working with WinXPE was identical to working on standard XP. I did not experience any performance issues either, but the application was not very resource intensive.

I've used WinXPE on a TPC with great success. I used an Advantech panel (TPC-1261) with a pre-configured distribution of WinXPE. We loaded up VISA run time and the LV run time and ran our application with no issues. We did start out using a panel with Windows CE and the TP module, but it was full of bugs and other issues.

Thanks Vinny.

I have done some sub-par GUIs on the TPC-2012 due to bugs, issues and general restrictions of using WindowsCE.

Since you have experience in both, is there a huge improvement over on screen graphics and general performance?

Is anyone using Windows Embedded XP on TPC development?

And can comment on the pros/cons including differences wrt Windows CE & using NI Touch Panel Module - especially graphics?

KB, KB, Dark Side Forum

I am interested to know the differences as the TP Module and Windows CE can be a pig to program compared to standard LabVIEW and Windows XP - don't take my word - go ahead try it

[Cross Post]

I want to mimic a standard windows tab look.

I use freetext as a header on a System Recessed frame which is on a System Tab to logically group controls.

However, depending on the height of the freetext, the background color of the freetext does not match the System Tab.

And no other system color seems to either?

Is there an easy work around for this?

To store the last value (n-1) from the previous iteration

You can also click on it and drag it down to get n-2, n-3 etc...

Go to the LabVIEW Help and do a search to find out more about it.
