How can I detect if LabVIEW is the active (frontmost) Windows application?

I need a way to figure out in LabVIEW 6.1 if LabVIEW is the "active" application in Windows. More specifically, I need to know if a user has switched to some other application besides LabVIEW. This needs to work on an EXE as well as VIs.

I also ran into this issue. The previous post can be solved easily by the new event structures, but I need to check if a panel is the frontmost in windows as well.
The FP.Is frontmost property returns if a panel is the frontmost Vi within Labview but not if Labview is the frontmost window in windows.
I ran into this as I am making some stuff to use the scollwheel.
As an example I have added two Vi's. Just load & run these, as long as Labview is active this works. But I would like to have something that switches the lights off when I select another Windows application.
I (think I) cannot use the USER32.dll API as I reconstruct a reference to the 'owner vi' using a control reference.
Anyone has some experience with this??

How can I shut off all of the pop-up windows for all the Firefox updates?

How can I shut off all of the pop-up windows for all the Firefox and Thunderbird updates?
Apparently now Mozilla creates new versions of their browser and email apps every two weeks instead of just creating updates... I'm tired of all of the pop-up requests for these constant installation requests and all the problems that the new version installations create... I just want to use the software and be left alone.
I can't find a way to make Firefox and Thunderbird stop with the pop-up requests for new installations... is there a way to do this or has Mozilla just got it rigged so one can't just use the software without re-installing a new version every two weeks and running in to new plugin issues and missing features every time?
Help!
Thanks,

If you restored the hard drive to its original factory-new contents using the Toshiba recovery media, then the problem is almost certainly due to malfunctioning hardware.

How can I make firefox switch to the first open window as soon as I click on it on the taskbar.

I'm running Windows 7 and when I click on Firefox on my taskbar and I have more then one window open, Firefox forces me to choose which window I want to go to. I would like it to always assume I want to go to the first window. How can I change this?

Go to Tabs in Options and uncheck ''Show tab previews in the Windows taskbar.''

How can you detect irregular edges using the IMAQ add on?

Im currently trying to use the IMAQ add-on for LabView to detect the edges of an irregular image. I have attached the image I am trying to detect the edges of. I have tried using everything in the "locate edges" sub-pannel (i.e.. imaq find edge, imaq find circular edge etc.) but none of them have yielded any favorable results. I think the "IMAQ edge tool 3 IV" might be what im trying to find however I don't understand how to get any usable data out of it.
Thank you, all comments and help are greatly appreciated.

Hi Dander,
I am not sure exactly what types of edges you are trying to acquire, but I used one of the examples from our Example Finder and was able to detect edges on your image. I will say that with the image that you are using, the edges are not very well defined, so you may not get a 100% accurate measurement. The example that I was using uses the IMAQ Edge Tool 3 VI and the example can be found by going in LabVIEW to Help>>Find Examples... From there, you will go to Toolkits and Modules>>Vision>>Functions>>Edge Detection Example.vi. After that, you will remove the build path function and input a path to the image. I hope this helps!

In applications, drag the install OSX 10.10.1 to trash. The download will not install unless you tell it to. You can download it without it installing, so trash it if you have decided you don't want it or simply don't tell it to install.

How can I detect the windows version from Forms 6i?
I was used get_application_property(operating_system); But it only return MSWINDOWS, MSWINDOWS32, WIN32COMMON.
Any function or way can return the exact windows version(98/ME/NT/XP)?

How can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

how can i do with labview program,when i have 20 different values,and 1 want to add it with constant value.and how to get the results?

Why do the 20 values have to be different? The same code should work even if some are equal.
What do you mean by "get the result"? The result is available at the output terminal and all you need is a wire to get it where you need it. That could be an indicator, another operation, or even a hardware device.
What is the data type of the 20 values? An array? A cluster? A bunch of scalars? A waveform? Dynamic data?

How can I detect in Business HTML that the app was called from portal?

How can I detect in Business HTML that the app was called from portal?
I need to distinguish whether the application was called from portal (URL iView) or by using an URL outside of portal.
So what I'm looking for is a variable or function that can be used like this:
`if (~within_portal==1)`
do this if called from portal
`else;`
do that if not called from portal
`end;`
For example, can I check in the program that there is a SSO2 cookie from the portal?
I'm using Integrated ITS in Basis 700.

Here is the trick:
if (sapwp_active=="1")
in portal
else
without portal
end;

How can I detect if I'm running a compiled versione of my application?

In my application I have included some special functions I don't want my customer to use. Since I will distribute the application as an .exe file, instead of cutting away those functions before releasing the .exe, I want to hide them when the application is runnig as an executable, and leave them active when running in the LV environment.
How can I detect if I'm running an executable or the LV environment? Do I have to scan the application name until I find an .exe different from labview.exe or there is another way to obtain the flag (something similar to CVI function InStandaloneExecutable() for example)?

How can I import data in to the digital word generator in Multisim?

How can I import data in to the digital word generator in Multisim?
I just received this comment from a friend, a RADAR engineer, who has just down loaded Multisim. He has been using HP/Agilent software. He has a work around using a piecewise linear voltage waveform with data imported from Excel but this is not really a good solution. It would also be helpful to import data from Mathcad or equivalent.
"I thought I was about to be impressed with MultiSim but it ended only in disappointment. There is a word generator in the simulation instrument panel which can drive the DAC with a waveform and it can have thousands of lines of values. I opened Excel, wrote the formula to generate the time and voltage points for a chirp, converted to DAC values in Hex and then went back to the word generator in MultiSim to load the values only to find that you have to enter each value manually. It doesn’t even allow you to paste in a list of values from a text file. I’m not going to type 5000 values by hand. If you get the chance to give feedback to National Instruments please ask them if the paste option can be added to the word generator. MultiSim is useful in many regards, but in this case, it left me with the impression that it is considerably limited in capability compared to what I’m used to."

Hi,
You can load your data automatically in the Multisim word generator. Follow these steps:
- Save your data file (in excel .xslx ir .csv format) on your computer
- Change the extension of the file to ".dp"
- Double-click the word generator in Multisim and click on Set...
- In the Settings dialog box, click on Load and then Accept
- This will prompt you to select the .dp file you have on your computer, select it and you're good to go
However, in Multisim you have the option of creating your own custom simulation analysis and instrument.
I will try creating the instrument and send it back to you but it might take some time.
Multisim and LabVIEW are very powerful in test automation, with the custom instruments you create for Multisim you don't need to export your data file into excel from LabVIEW (or MathCAD or other tools) and then reload it into Multisim. The test procedure is automated instead.
Please check this reference design about automated simulation
http://zone.ni.com/devzone/cda/tut/p/id/7825
Here is how you can create your own custom measurement tool in Multisim and LabVIEW, but as I mentioned, I will create the word generator and come back to you anyways
