the event structure cannot combine with other events and run only once
Why it will always get stuck when I combined the 'new user add' event to the event of 'Login '?
It works for me when I separate the two, but the 'Add a new user' button can work but only once for the structure above, program will be blocked on the second time that I press the button "add a new user".
It has already been said, you must use that a single structure of the event and not 2. Also, avoid using local variables (better store data in a shift register and not in an indicator) how you do it, it can cause bad racing conditions.
Actually here you just don't another data storage since you have a file. Don't store data file to the root of the C drive, you do not have write permission. Use the default data folder or the folder of the application.
I have attached a simple example. I guess that's a work at home? Please make my account help: try to understand why your VI does not work and try to find a solution by yourself. Modify my sample and play with him. This is how you learn LabVIEW. If something is not clear, post here, and we can explain/help.
Edit: has the 'connection' event, I don't check against whether the file exists or not. Difficulty of this part, gives too little practice.

Using an IP191 monitor, have random horizontal stripes on the screen - have no problems with other browsers. also no problem with FF on the other PCs on the family.
These "streaks" seem to be the domain of the high frequency analysis; they can be eliminated by scrolling upwards or downwards.
Hello, maybe it's a problem with hardware acceleration - try updating your graphic driver, or in case this does not solve the problem, or there is no new version available at the time, disable hardware acceleration in the firefox menu

While the loop within a box Structure runs only once a target FPGA
I have a card OR cRIO-9012 RIO for the HIL system. I have a target FPGA file when I use a While loop within a while loop I use the box Structure to check a real condition inside I have the function of activation of the ports and selecting the analog and digital ports. But for my code the code runs only once on repeted times that we have in the LabVIEW environment.
I also need help to optimize the code. I've seen people using While loop timed in the FPGA target I don't use in both cases.
I've attached my FPGA with the Version of LV2012 file.
Waiting for your comments.
Thank you and best regards,
Ganesha Moorthy
You have while loops inside the structure to deal with a constant of false cable to the stop condition. These loops will obviously never stop so browse your outside while loop (containing the case structure) can never.
This has nothing to do with the FPGA target, the same thing will happen in the development environment.

Can I set up a folder with many files and give only a limited number of people access? Just as in the old system.
Hi oliviner,
If you are referring to the workspaces, then yes it is possible but the service will be removed in January 2015
If you are referring to files.acrobat.com, so if you can create folders and put the files into it, but you cannot assign access to specific people as you could in workspaces.
Kind regards

Why Lightroom CC will not download Nikon D610 photos, the same problem, I got with lightroom 3 and said to upgrade?
Make sure you sort the display you are looking at instead of file name recording time. It is in the context menu with a small sign of a to z just below images. Make sure also that you have no active filters.

How do I re name and renumber a folder of photos and include four numbers starting with 1 0001 and not only the numbering. I need this for an another computer program can keep the images in numeric order
Now I have number say marriage... 1 Smith_Jones ect up to 659, but a program that I use to create the albumes blurs all my photos because they say the digital system must have 4 digits so number 1 is 0001 so stay in order. I have d see how to assign 3 zeros on numbers-# 344 front would therefore 0344 LR wants to keep 344.

My new Publisher El 12 runs only once after restarting the PC - how to fix?
My new publisher of 12 items, runs only once after restarting the PC and seems to work well. I did a "clean install" repeatedly (cleared Temp files, shut down all applications, including Norton Antivirus and then installed DVD after a clean reboot). I can launch organizer of 12 elements several times, but the photo that editor runs only once. After that, I have to restart the PC, and then I can run the Editor again, but once again, only once. I also first 12 items for video files - no problem, he launched several times. I see that Alfredo has a similar problem: How can I fix?... is it a bug of El 12?... Thanks for your help... k-paul
Thank you very much Peru Bob... your statement works... of course, this stitching is 12 items of closing/out not really closes it (which is why I could not re - start it), so there's always a problem... I can live with that, but why would the program stops not when I close?... k-paul

When I use the library function node call in real time, is loaded only once for all or load the DLL every time when it is called?
I have a critical application in real time, in which I use a piece of DLL function developed in C++. It is ok? Make sure any senior developer?
Thank you in advance.
The user interface thread is the thread that is used to update the user interface. It's slow. And it's supposed to be that way because humans are slow.
The call library function node can be configured as this thread to use in the configuration for it dialog box. Please visit the LabVIEW documentation on how to do this.
