Open Serial Driver VI runs in user interface thread - why?

I know the serial port compatibility functions are "phased out" and you should use the newer VISA functions - but why on earth is the open serial driver VI set to run in the user interface thread? If you happen to use these compatibility VIs your serial communication will be blocked by e.g. a user that opens the calendar view of a date and time control...- and the only reason for that is that that particular VI is running in the user interface.
Change the thread of that VI - and the serial communication runs as it should, so why is it that that particular VI, unlike all the other VIs in that library, is configured that way?

The S/N dialog is part of the process model.
For the Sequential Model (SequentialModel.seq), the default S/N dialog in found in the 'PreUUT' sub-sequence and implemented as a DLL call.
The PreUUT sub-sequence of the SequentialModel is a callback, so you can override it in your own test sequence.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

How can I give the "user interface thread" higher priority?

We do alot of activex calls to front panels. We need to increase/decrease the priority of the user interface thread to resolve our thread problem. Anyone know how to do this?
Chuck

Hello,
As P.M. was saying, you can adjust the thread priorities
through the VI Properties dialogue.
Another place to modify the multithreading system in LabVIEW is a VI
located at: [LabVIEW Directory]\vi.lib\Utility\sysinfo.llb\threadconfig.vi. However I do not think this will remedy any
problems you are having.
From a Multithreading in LabVIEW tutorial (http://zone.ni.com/devzone/conceptd.nsf/webmain/d2e196c7416f373a862568690074c759)
Priorities in the User Interface and
Single-Threaded Applications
Within the User Interface execution
system, priority levels are handled in the same way for single-threaded and
multithreaded applications.
In single-threaded applications and
in the User Interface execution system of multithreaded applications, the
execution system queue has multiple entry points. The execution system places
higher priority VIs on the queue in front of lower priority VIs.
If a high-priority task is running and the queue contains only lower priority
tasks, the high-priority VI continues to run. For example, if the execution
queue contains two VIs of each priority level, the time-critical VIs share execution time exclusively until both finish.
Then, the high priority VIs share execution
time exclusively until both finish, and so on. However, if the higher priority
VIs call a function that waits, the execution system removes higher priority
VIs from the queue until the wait or I/O completes, assigning other tasks
(possibly with lower priority) to run. When the wait or I/O completes, the
execution system reinserts the pending task on the queue in front of lower
priority tasks. Refer to the Synchronous/Blocking Nodes section for a list of
asynchronous functions that wait.
Also, if a high priority VI calls a lower priority subVI,
that subVI is raised to the same priority level as the caller for the duration
of that call. Consequently, you do not need to modify the priority levels of
the subVIs that a VI calls to raise the priority level of the subVI.
Thus changing the priority of your VI will change the
priority of UI calls for that particular VI.
Again, I caution you because I suspect that if you are having problems
with your application not running correctly, I do not believe that manipulating
the thread priorities will resolve these issues.
Hope this helps,

User interface threads

Ok let's say you're writing a user interface and nothing involves
special-resources like a daqcard so there's no constraints on using things
at once. These are some kind of stupid questions and ideas but I'm really
not sure how to write a quality app with user interface at the moment.
My current design is bad, it is a mainVI which checks the menu and
frontpanel buttons, decides which operation or calculation (if any) is
selected, and sends that to a case structure to perform the operation.
This is sloooow but the most common way in examples that I've seen. The
major problem is that while processing the interface isn't checked and
therefore mouseclicks might be lost. Let's say the processing takes like
500ms on average, that is kind of slow between user-interface querys so it
would feel unresponsive in the mean time.
So here's my three ideas so far, I'd love some comments on what will be FAST
and what would be worthwhile to spend my time on:
1. Leave the app as-is, latch the booleans. However you can't latch
mouse-clicks on a picture indicator that I knew of. I emailed NI before
about this and they just suggested adjusting execution priorities. Anybody
else messed around with this? Probably the worst option, but would take zero
programming.
2. Divorce the user interface and the processing. Create two parallel
while-loops in the same VI, one checks the buttons/menu on the front panel
the other processes the request or calculation. Let's say on average UI
checking takes 1.2ms and processing takes about 500ms. Also in this case is
the watch icon still really my best option (since checking buttons/menu only
takes like 1.5ms on average) for not wasting time repeatedly checking when
there's no input and dividing up cputime accordingly? Seems like there'd be
some overhead in switching back and forth repeatedly.
3. Going all-out and changing to somewhat of an object structure. That way
the UI could create a new "execution" refnum, maintain some list of created
objects, process, return values, destroy any object, so everything could be
going on in parallel. That way one slow calculation won't bog down the rest
of the things the UI requests. The idea is far too abstract to me at this
point, but on a single CPU w98 system is it even worth my thinking about
such a structure? I get the feeling I'd see zero performance change between
the two, in fact maybe worse from any labview thread overhead!
Thanks for any comments. I have seen DAQ intensive apps discussed often, but
don't usually catch much on large user interface apps.

Hi Joey
First check are you are not recalculating the values on ever iteration of the user interface loop but are you only recalculating
on any change in the user interface values.
Otherwise I would use idea No. 2 but with these changes.
1. Only check the whole user interface every 200-300ms, 1.5ms loop time will unnecessarily load the CPU.
2. Each user interaction could be given a string representation and then placed in a queue to wait for the calculation loop to
have time to process it.(So the user instructions are not lost)
3. Have separate loops for faster and slower calculations (or more) with each having their own queue.
4. The extension to the idea's of having separate loops, is to have each loop in a separate independently running VI (see
VIserver). Still use the queue's to pass the data. This method would allow the calculations and the user interface to run on
separate threads and also lets you alter the execution priority for each VI to fine tune the execution times.
Following these instructions you would produce a basic client-server architecture for your user interface, as long as the UI
doesn't require too many slow calculation results before continuing then this should work well.
If this is still not fast enough then, if you have used suggestion No.4, the calculations can be moved off the users computer to a
faster server (using VIserver) also assuming they are networked.
Hope this gives you some ideas.

Run / quit user interface and memory clean up

Hi,
may be I simply miss a coffee, but here is my problem: I have a main function and a quit callback in a standard configuration, i.e. as follows:
int main ( int argc, char *argv [] )
    RunUserInterface ();
    DiscardMenuBar ( popup_menubar_handle );
    DiscardMenuBar ( menubar_handle );
    DiscardPanel ( panel_handle );
    return ( 0 );
int CVICALLBACK Quit ( int panel, int control, int event, void *callbackData, int eventData1, int eventData2 )
    if ( event == EVENT_COMMIT )
        FreeDynamicMemory...
        FileCloseFiles ...
        QuitUserInterface ( 0 );
    return ( 0 );
On the panel, there is a graph with plots etc. If I quit the program via the quit callback (i.e. a Quit button), everything is fine, no memory leak.
If I try a modified version as shown below, plots are not freed after the program has finished, resulting in a memory leak as shown by the resource monitor:
int main ( int argc, char *argv [] )
    RunUserInterface ();
    return ( 0 );
int CVICALLBACK Quit ( int panel, int control, int event, void *callbackData, int eventData1, int eventData2 )
    if ( event == EVENT_COMMIT )
        FreeDynamicMemory...
        FileCloseFiles ...
        DiscardMenuBar ( popup_menubar_handle );
        DiscardMenuBar ( menubar_handle );
        DiscardPanel ( panel_handle );
        QuitUserInterface ( 0 );
    return ( 0 );
I have also tried reversing the order in the quit callback, with the same result:
int CVICALLBACK Quit ( int panel, int control, int event, void *callbackData, int eventData1, int eventData2 )
    if ( event == EVENT_COMMIT )
        FreeDynamicMemory...
        FileCloseFiles ...
        QuitUserInterface ( 0 );
        DiscardMenuBar ( popup_menubar_handle );
        DiscardMenuBar ( menubar_handle );
        DiscardPanel ( panel_handle );
    return ( 0 );
So only the first variant works properly and I could be happy.
However, I do not understand why version 2/3 do not work.
Second, the first variant does not work if I also have installed a main callback, see the other thread here That's why I tried variants 2 and 3 but failed...
Thanks for the coffee

Off the top of my head, I can't think of any reason why the 2/3
alternatives wouldn't work. This might be a bug in the resource tracking
detection.
I tried to reproduce the problem with a simple program, but I wasn't
able to. I'm attaching my files. Can you try them out and see if you can
reproduce the problem with them? If not, can you try attaching some
project that reproduces it, so that I can look into it?
Thanks,
Luis

How to avoid long user interface response time in long measurements ?

Hi
I tried to find more information regarding techniques how to avoid long user interface response times in case of extremely long measurement times with an external instrument communicating over GPIB, so I post this hoping to get some hint or a link to a guideline. I guess this is quite normal problem.
Problem is that when I want to measure long time in order to get an average result from the instrument, I have to wait until the result is returned from the instrument. Obviously that makes the user interface response very slow in traditional technique.
My restriction is the old GPIB 488 instrument driver that I would not want to modify, but I have source code to it.
What would be the best way to improve the response time for user interface ? I have looked into the few things:
* multithreading
* callback in main program for GPIB events
* modifying instrument driver e.g. to support VISA and creating a VISA callback
regards,
Petri

Several ways to do this:
If you're getting several measurements, you could have the instrument generate an asynchronous interrupt (an "SRQ" in GPIB terms), then collect the data in response to the SRQ callback. While you're waiting for the SRQ's, you can have your main thread running the interface so responsive GUI. You don't have to spinlock on the GPIB read waiting for instrument data.
Or, as you mentioned, you could spawn a thread to manage the measurements, and use a timer in the main thread to periodically allow you to check the status of the measurement thread. Again, the main thread mostly just runs the user interface.
Either way, the idea is to keep the main thread freed up most of the time to run the GUI, and have it periodically check for completion of your measurement sequence. While you're waiting in the main thread, you may want to make sure the user can't inadvertently re-trigger another measurement sequence until the active one is complete.
If you do find yourself doing a dead wait, you'd want to break this up into a series of shorter waits, and in between each wait, do a ProcessSystemEvents from the main thread to keep the GUI active.

LabWindows/CVI Remote User Interface

I have an application that I would like to modify to enable running the User Interface Panel from a remote
computer. I have found articles on doing this with LabView. Can this be accomplished using LabWindows/CVI 7.0/7.1 ?

Hello Hornsbyr,
It is possible to have run remote front panels in LabWindows/CVI. First you would need the CVI Enterprise Connectivity Toolkit as an add on to 7.0 or 7.1. A web server is included in the Enterprise Connectivity Toolkit. By setting up and connecting to the web server, you will be able to monitor and control the operation of your front panel through a web browser. The INET_RegisterPanelAutoUpdate function is used to export a LabWindows/CVI user interface panel onto the Web. Once a client requests the image of the panel, the server periodically sends an updated image of the panel.
The image of the user interface is sent as a JPEG image, but as stated in the LabWindows/CVI Function Help, the JPEG will not include your UIR's menu bar, title bar or borders.
I have attached a document that further describes how to control your front panel remotely.
Also, here is a link to the product pricing sheet: http://sine.ni.com/apps/we/nioc.vp?cid=11128〈=US

Illustrator CC 17.1.0 crashes when editing preferences, user interface. Running on MacBook Pro i7 OSX 10.9.5

Illustrator CC 17.1.0 running on MacBook Pro i7 OSX 10.9.5 - crashes when editing preferences, user interface. Also crashes when quitting application. Anybody any ideas?

While 2 GB is the absolute minimum to install Mavericks, if you want to do anything with the Mac you need more then that. Upgrade your RAM.
Until you upgrade the RAM seriously consider shutting down the Mac nightly. You should also seriously review the items in the User Login Items to see if there are any there that you really don't need to have startup with your login to reduce the amount of RAM you are using.

How can I make a flash user interface with buttons to open up and navigate other flash files?

Hello I would like to make a user interface that will serve as a tool to load and unload other flash materials like a slideshow. I would like to make a kind of slideshow with Flash that opens up other flash files which could be around 10-15 slides (frames) long each. I would want to ask if there is any way to make a link between navigation and other slides easily. And if there are ways, what action codes should I use for this. Thank you very much.

All you need to do is load a swf into the main swf and target it with whatever controls you intend. If you are using AS3 then you could use the Loader class to load the swf and then target the Loader.content with your control buttons.

After downloading osx 10.9.2 when i open my logic pro 9 and begin to audition loops that came with lp9 i get a message that says "audio device has been removed and then a second message the " select driver not found(-10202). my interface is a apogee duet

after downloading osx 10.9.2 when i open my logic pro 9 and begin to audition loops that came with lp9 i get a message that says "audio device has been removed and then a second message the " select driver not found(-10202). my interface is a apogee duet. Can anyone provide a solution to this problem. Thanks

YES!!! YES!!! YES!!!
I got it!!! Yes!!!
Guys, I've solved my problem about that error -10202 (Selected driver not found).
I have installed in my Mac Pro (OS X 10.5.8) a document with an extension ".rsrc" to correct the position of the accents in my keyboard, like acute accent, tilde and circumflex.
That file is called "U.S. - International.rsrc" and it's stored in the following path:
"Macintosh HD/Library/Keyboard Layouts"
So, when it's properly installed, I can choose 2 country flags on the right side of the menu bar (U.S. - International and Brazilian).
That's the clue!
When I pick up "U.S. - International", my keyboard works fine with the accents, >>>BUT<<< Logic Pro 9 doesn't recognize my audio driver; and when I pick up "Brazilian", my keyboard doesn't work with the accents exactly as it shows me on each key, BUT Logic Pro 9 DOES recognize my audio driver.
So, when I want to write anything out, I will pick up the "US - International" and when I want to work on the Logic Pro 9, I will pick up "Brazilian".
I hope I can help all of you.
Regards,
Renato Veiga.

Using LabView to serial interface my microscope how I make a user interface to make the stage move by pressing buttons?

I have used LabView very little and am trying to write a program to control a microscope. I want to be able to give it commands such as to get the stage to move left, right, forward, back, and return to zero. I'm having trouble implementing the code into my block diagram. I've been reading LabView 8.6 tutorials for a couple of weeks and I'm still learning. What I know that is that I need a event structure inside a while-loop for the user interface but I've been stuck.
Thanks for any help! If you need me to try and provide more information please say so.

Button.vi ‏21 KB

Alright so my serial port code should be inside a while loop unfortunately it doesn't work whenever I enter a command to move the stage. It sits there maybe I'm missing something.
So let me give you an overview to what happens in my code, so the configure serial port is very crucial. The VISA Write writes the bytes to the port. The first VISA Write takes the string to write command. I connected the second VISA write to make it easier whenever I enter a command, the \r will iniate the command as a whole. Example L\r will move the stage to Left once, ending up at VISA Read then closing. All of this found in separate case structures.
Now the user interface to control the the movement of the microscope is one of my issues, making several attempts to make it work yielded no results. My best work not the best but a attempt is attached, also one of the things with this I'm having trouble with is getting the button to talk to the stage. On previous buttons I worked on I could press the button and light up an LED on the front panel, I thought the same principle would relate to the movement of the stage, no such luck.
I hope I cleared up some misconceptions on my part, I appreciate your patience.

How to make sure the addon is running when user open the SAP B1 client?

Hi,
Is it possible that that we can set somewhere in SAP B1 setting and without running addon user can not login into SAP B1 client? I tried even set the addon to Mandatory in addon administration, but user still can choose running without addon. Any suggestion ?
Thanks!
Lan
Edited by: ZHANGLAN on Aug 19, 2010 10:49 PM

Hi All,
Maybe I didn't describe my situation clear enough. I have lot of lient PC with different environment, i am always be reported that the AddOn doesn't work. In most case they are caused by some unexpected reason like anti-virus softeware or windows update. If the addon crashes then user lost everything in addon and they will starti complaints... My idea is to make the addon as mandatory requirement before user can start to use SAP B1. But for now, the setting in addon administration is more like an option, end user still can be allowed to run SAP B1 without addon.

Mobility Radeon HD 5000 Series + open source driver = screen flickers

Hello, this is my first post here. I just finished setting up my first arch installation on my laptop and I'm using Xorg + gnome 3 as user interface.
My laptop has two VGA cards, an integrated intel VGA card and a Mobility Radeon HD 5000 Series, so I used vgaswitcheroo to switch to the Mobility Radeon and turned off the intel VGA card.
Now, here's the problem: I want 3d acceleration to play games and such, but the opensource radeon driver is being weird.
Basically, if I use my Mobility Radeon and the opensource driver the lower-center part of the screen flickers when i move windows vertically. It flickers to black in a polygon-like area and the window shadows get all messed up. If i try to start a game that uses 3d acceleration (such as nexuiz) it runs extremely slow (way too slow for this VGA card) and flickers like crazy in the same area and sometimes on the entire screen.
I already tried using the proprietary driver (catalyst) but it doesn't seem to support switchable VGA cards, since it gives me memory segmentation error.
However, if I switch back to the Intel VGA card and use the opensource intel driver, it runs just fine with no flickering and nexuiz runs better (but of course not fast enough since the intel VGA card is crappy)
As you can see here, 3D acceleration seems to be enabled and Xorg doesn't seem to give any major error or warning:
