Running a Front Pannel and SubVI on different monitors when using a DAQ

I have developed a test rig monitoring system. Since there are a large number of transducers and thermocouples I have had to divide the monitoring system into two parts. An air system Front pannel, which is interactive,alloying me to start stop pause the program, and a fuel system SubVI which is purly for displaying information. When the front pannel is opened I would like the SubVI to be displayed as well. I dont mind waiting for it to be called by data being sent to it, but since data will be constantly sent to it I dont want it continnuously called. Basically I want it there running in the back ground so that I can acess it whenever I need it but I dont want it getting in the way. Does this make sense?
Thanks

They will be running on different monitors from the same PC. To allow us to view both at the same time. The problem that I am having right now is that the window is being continuously called through the data, so it will appear and disapear. If i select the close if originally closed option, and I open the subVI originally, then it will stay open for awhile then start to open and close again. I think this a labVIEW softwear issue as it happends at a different time each time I run the program. The other issue is that I need the Front Pannel to be the active Window, but not necesiarily on top.
Hopefully this makes more sense, I can attach the program if you like, but it is pretty large and requires a number of subVI's and the keithley 2700 driver package

Do IMAQ Cast Image or IMAQ Linear averages give different results when using different computers that are running under Windows XP ?

Hello
I'm currently developping an image processing algorithm using Labview 7.1 and the associated IMAQ Vision tools. After several tests, I found a weird result. Indeed, I put the labview algorithm - including the IMAQ VI on the library to get sure that I use all the time the same VI - on my memory stick and used it on two different computers. I tested the same picture (still in my memory stick) and had two very different results.
After several hours trying to understand why, I found that there were a difference between the results given by both computers at the very begining of the algorithm. Indeed, I used a JPEG file.
To open it, I first create an Image with IMAQ Create (U8). Then, I open it.
Then in my first sub-VI, I use IMAQ Cast Image to be sure that the picture is a U8 grayscale picture.
Right after that, I use the IMAQ Linear Averages. The results of this VI are different on the two computers.
I tried several time on the same picture : one computer always give me the same result but the two computers give me a different result. So there is no random variable on the results.
So my question is : Do IMAQ Cast Image or IMAQ Linear averages give different results when using different computers that are running under Windows XP ?
My bet is on IMAQ Cast Image but I'm not quite sure and I do not undestand why. The labview and IMAQ are the same on both computers.
The difference between the two computer are above :
Computer 1 :
Pentium(R) 4 CPU 3.20GHz with a RAM of 1Go. The processor is an Intel(R).
The OS is windows XP Pro 2002
Computer 2 :
Pentium(R) 4 CPU 2.80GHz with a RAM of 512Mo. The processor is an Intel(R).
The OS is windows XP Pro 2002.
If anybody can help me on this problem, it would be really helpful.
Regards
Florence P.

Hi,
Indeed it's a strange behaviour, could you send me your VI and your JPEG file, (or another file that reproduces) so that I could check this inthere ?
I'll then try to find out what's happening.

I have this on both machines running 10.10.1 OS X and AE 2014. I see on line that others are having this issue. I think it needs a Patch ASAP.

Hello. Basically I can create a new comp that is set to 1920 x 1080, @ 30 frames per second for 1 minute TRT. I create a new solid layer, say red. I hit space bar or play on the screen, and it does not play in real time. ITs on my Imac as well. same OS and Same Version software.

Since installing LTR 5.4, which I've now upgraded to 5.6, I've encountered repeated slowness and malfunctions in operations, especially when using the Compare View function and the Tab key to open and close the right and left side panels. Such problems never arose during two years of using LTR-4 and nothing else has changed on my computer. I have a pretty simple system with only a few plug-ins, which are usually not in operation. I have 12GB of RAM in my Windows 7 PC. I could illustrate these problems with screen shots if you would tell me how to submit screen shots. Otherwise I will try to describe the problems in words.
The problem is clearly cumulative, growing worse as usage time passes. Compare View feature gradually slows down and eventually seems to choke as my work session proceeds. If I Exit LTR and re-enter and start all over, things will work normally for maybe 30 minutes, but then the Compare View feature begins to become very slow to respond. In a recent example with my screen full of thumbnails in Library mode I highlighted two images to compare. LTR started to open the Compare View screen by first having the top row of thumbnails disappear to be replaced by the "SELECT" and "CANDIDATE" words in their spaces (but no images), but Compare View never succeeded in gaining control of the screen. After some seconds the top row of thumbnails reasserted its position and the Compare View windows disappeared. But LTR kept trying to bring them back. Again the top row of thumbnails would go away, Select and candidate would reappear, try again, and give up. This went on for at least 2-3 minutes before I tried to choose File and Exit, but even that did not initially want to respond. It doesn't like to accept other commands when it's trying to open Compare View. Finally it allowed me to exit.
To experiment I created a new catalog of 1100 images. After 30-40 minutes, the Compare View function began to operate very slowly. With left and right side panels visible and two thumbnails highlighted, hitting Compare View can take half a minute before the two mid-size images open in their respective SELECT and CANDIDATE windows. When the side panels are open and two images are in the Select/Candidate spaces, hitting the Tab button to close the side panels produces a very delayed response--25-30 seconds to close them, a few more seconds to enlarge the two images to full size. To reverse the process (i.e., to recall the two side panels), hitting Tab would make the two sides of the screen go black for up to a minute, with no words visible. Eventually the info fields in the panels would open up.
I also created a new user account and imported a folder of 160 images. After half an hour Compare View began mis-placing data. (I have a screen shot to show this.) CANDIDATE appears on the left side of SELECT, whereas it should be on the right. The accompanying camera exposure data appears almost entirely to the left of the mid-screen dividing line. Although the Candidate and Select headings were transposed, the image exposure data was not, but the data for the image on the right was almost entirely to the left of the line dividing the screen in two.
Gurus in The Lightroom Forum have examined Task Manager data showing Processes running and Performance indicators and they see nothing wrong. I could also send screen shots of this data.
At this point, the only way I can process my images is to work 30-40 minutes and then shut down everything, exit, and re-start LTR. This is not normal. I hope you can find the cause, and then the solution. If you would like to see my screen shots, tell me how to submit them.

The problem is with the new operating system and sending photo via email when used in my iPad.
From photo I selected 3 photos to send via email. I choose the upload key and choose to send by email. Typing text on the email is very slow. This is solved by saving the email as a draft and opening the email again from mail.
Can you amend he system to allow emails to be sent from photo as previously.

Have you tried restarting or resetting your iPad?
Restart: Press On/Off button until the Slide to Power Off slider appears, select Slide to Power Off and, after the iPad shuts down, then press the On/Off button until the Apple logo appears.
Reset: Press the Home and On/Off buttons at the same time and hold them until the Apple logo appears (about 10 seconds). Ignore the "Slide to power off"

Hi Buterem,
I'm sorry to hear you are having issues with your MacBook Pro since your recent Yosemite update. I also apologize, I'm a bit unclear on the exact nature of the issue you are describing. If you are having intermittent but persistent responsiveness issues with your mouse or trackpad, you may want to try using Activity Monitor to see if these incidents correspond to occupied system resources, especially system memory or CPU. You may find the following article helpful:

If the entire system hangs or locks up (for example, if the system clock freezes and stops counting up), you may also be experiencing some variety of Kernel Panic. If that is the case, you may also find this article useful:

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

Set front panel size to fit different monitor ( 2 monitors-pattern to 1 monitor-pattern)

Hello, Everybody,
I have here some questions about front panel size.
At first I have create my LabVIEW programs with 2 monitors and run them with 2 monitors, because of this reason I have created a huge front panel with many objects.
But sometimes I will run the program only with 1 monitor, the problem is, the front panel is too big, I can not see the front panel with all objects completely on one monitor! I know, I can scroll aroud it, but I don´t like this way. I would like to set the front panel size automatically to fit the window ( to differenz window sizes or resolutions), how can I do that?
I have tried with "Maintain proportions of window for different monitor resolutions" and "Scale all objects on front panel as the window sizes" to finish that, but they did`t work, I can not see the front panel at once on one monitor;-(
Can you help me?
regards,
Johnny

As noted in the KB article What Is the Difference Between the Options
"Scale All Objects on Panel" and "Maintain Window Proport..., the "Scale All Objects on Panel causes all the objects inside the panel to scale when the panel itself is resized". If the panel isn't resized, the objects arent's scaled. You may also want to read the KB article How Do I Scale All of the Objects of My Front Panel with the Window Size?.

Can't I use my wireless mouse and trackpad in different ways when scrolling?

Since I'm a Chinese user, I prefer describing my question in my mother language...I will translate it...
在系统偏好设置里，倒是可以分别设置鼠标和触控板，但是当我打开触控板的“自然滚动”，同时取消鼠标的“滚动或导航时，使内容按手指方向移动”，之后，鼠标恢复原来的滚动方式，郁闷的使触控板的滚动方式也跟着变化了⋯⋯
但这时打开触控板的设置，“自然滚动”依然是选中的啊⋯⋯
如果这时关闭“自然滚动”，再重新开启，鼠标设置界面的“滚动或导航时，使内容按手指方向移动”虽然是为选中的，但使用时滚动方向又变成反向了⋯⋯
各位有遇到么⋯⋯我觉得是个BUG吧，期待修复⋯⋯

Well, there is two setting items in system preference for "mouse" and "trackpad", and there do have the checkbox for "Move content in the direction of finger movement when scrolling or navigating" and for "Scroll direction: natural". I checked the "Natural Scroll"---- if I may call it this way ---- option and unchecked the same option in mouse setting wishing to use my mouse and trackpad in different ways...
However, it turned out to be a confusing phenomenon like I can only use my mouse and trackpad in the way "Natural Scroll" or the way it used to be. If I double click the checkbox of "Move content in the direction of finger movement when scrolling or navigating" to refresh my settings, both my mouse and trackpad will turn into the way it used to be in scrolling while if I double click on the "Natural Scroll" checkbox, both of them will turn into the new way.
At the same time, eventhrough the setting of my mouse has been changed by the changing of trackpad setting, the checkbox in "mouse" is still unchecked and that's where makes it seems like a BUG....
So, is there anybody who meets the same problem? The reason I want to use this two device in different ways is I just don't like to use mouse in the new way, it's unconfortable for me.
And, I use a new MacBook Air 11' and a wireless mouse called Rapoo 6900
Here comes the link of my wireless mouse.
http://en.rapoo.com/ProOverview.aspx?PID=3550

jhawk,
I can see the appeal of your desired setup, but is the limitation the inability to "Pair" the mouse/keyboard to more than one computer at a time? (Practically, that makes sense, you don't want to be blindly moving both cursors around at the same time, since you can only see one screen at a time)
You CAN operate bluetooth devices on Windows without pairing-you just need to locate the device each time before using:
http://www.oreillynet.com/pub/a/wireless/2003/09/18/winxpunwired.html
So maybe you can pair the Mac version, and just search out the device each time you switch over? (but then you would have to "unpair" it off the Mac too) Maybe you need to write two scripts for each platform: pair/unpair devices.
Sounds like it would be easier to buy two wireless keyboards and mice :P
What you really want is a utility like this:

(its only Mac to Mac though, unfortunately)
Good luck!

Lots of different errors when using Maps on Linux, help?

I'm trying to use Maps in one of my programs, but for some reason I get all sorts of different errors when compiling.
I've tried both my own (very) simple tests of it and also I've copied and pasted the code straight out of the official tutorials.
//Edit: Ok, I've tried it on several different IDEs, and Netbeans (on both Linux and Windows) and JCreator(on Windows) both work now for whatever reason. The only one I still have problems with is below.
Here some of the errors I get, and nothing is making sense.
On a Linux machine, using a simple IDE (Geany):
MapTest.java:6: not a statement
Map<String, Integer> m = new TreeMap<String, Integer>();
^
MapTest.java:6: ';' expected
Map<String, Integer> m = new TreeMap<String, Integer>();
I don't know why it isn't working.

What do IDEs have to do with this? It's a compiler error.
Do you import java.util.Map and java.util.TreeMap?
Are you using JDK 5 or higher? Generics didn't appear in Java until JDK 5.

I am unable to scroll up and down with my mouse when using email.

When I load email, most of the time I am unable to scroll with my Magic1 button mouse. I can scroll just fine in any other application. I am using an iMac OSX 10.9. If I load any other program, I can scroll just fine.

First, try logging in as another user and see if the problem persists. The Guest user would be sufficient.
If it doesn't happen in another account, we can dig into yours to try to figure out what is causing it.
Second (if it fails in other account), boot into Safe Mode and see if it still occurs. Safe Mode disables third-party startup items which may be causing the problem. http://support.apple.com/kb/ht1455
If it doesn't happen in Safe Mode, then we can look at what is running in the background and guess at what might be causing that behavior.
Note that sometimes problems like this can be resolved by logging out and back in or by a restart.

Regular Expression: Different results when using FIND or regex classes

Hi,
has anybody an idea why the FIND REGEX statement and the regex class delivers different results when searching for
^\*
in
I try to find every place with an asterisk as first sign of the line.
The FIND statement
DATA gv_string        TYPE        string.
DATA gv_pattern       TYPE        string.
DATA gt_match_result TYPE        match_result_tab.
gv_string = '****'.
gv_pattern = '^\*'.
FIND ALL OCCURRENCES OF REGEX gv_pattern
                           IN gv_string
                      RESULTS gt_match_result.
returns one hit as expected. But the class cl_abap_regex and cl_abap_matcher returns four hits in this example:
DATA gv_string        TYPE        string.
DATA gv_pattern       TYPE        string.
DATA gt_match_result2 TYPE        match_result_tab.
DATA gx_regex         TYPE REF TO cl_abap_regex.
DATA gx_matcher       TYPE REF TO cl_abap_matcher.
gv_string = '****'.
gv_pattern = '^\*'.
TRY.
    CREATE OBJECT gx_regex
      EXPORTING
        pattern = gv_pattern.
CATCH cx_sy_regex .
    BREAK-POINT.
    EXIT.
ENDTRY.
TRY.
    CREATE OBJECT gx_matcher
      EXPORTING
        regex = gx_regex
        text = gv_string.
CATCH cx_sy_matcher .
    BREAK-POINT.
    EXIT.
ENDTRY.
gt_match_result2 = gx_matcher->find_all( ).
BREAK-POINT.
Looks like the class doesn't consider the start of line symbol (^). Is there an error in my implementation?
Any help is appreciated.
Matthias

Hi Jim,
thank you for your reply. But to negate a value set of single characters you have to use
[^ ]
I used just the character
^
This is defined as anchor character for the start of a line (See the documentation link you posted -> chapter 'Special characters for search strings') .
As I understand it, should the FIND REGEX statement does the same as the CL_ABAP_REGEX and CL_ABAP_MATCHER classes. Therefore, I do not understand, why both implementations deliver another result.
And I didn't find an answer for that. Does anyone else?
Matthias

Increased fan noise, CPU temp and random fan rpm bursts when using Leopard

I have a 2.2 Ghz Macbook Pro that I purchased in August 2007. I was running OS X Tiger on my mac till about a week ago when I decided to upgrade to OS X Leopard. Ever since the install, I've been facing numerous problems and issues with the general functionality of the computer. Specifically, the biggest issue relates to increased fan noise and random bursts of increased fan rpm (as monitored using iStat). I did not have any of these issues when using OS X Tiger. Further upgrading to 10.5.1 wasn't helpful either as it did not resolve the issue.

Welcome to Apple Discussions!
It may be worth running the Apple Hardware Test, just in case you have a sensor going out or something like that. Sometimes and upgrade will cause an underlying problem to make itself known.
Did you do an Upgrade as opposed to an Archive and Install or an Erase and Install? If so, there could be some software problem associated with the issues you are having. I tried an Archive and Install, and had so many issues that I went ahead and did an Erase and Install. I've had no problems since.
Good luck!
