Is there a way to determine if a camera IMAQdx session is still valid or not?

If it is valid, IMAQdx Open Camera.vi will return an error.

If it is not valid, IMAQdx Close Camera.vi will return an error.  And IMAQdx close Camera.vi is very slow during the in camera session is invalid.

I mean IMAQdx Camera.vi open have not yet been called, or IMAQdx Camera.vi Close has been called.

Although there is no node property for this purpose, other properties, such as the name of provider of camera, are acceptable workaround solutions.

  • Is there a way to determine if an application is 32-bit or 64-bit?

    Is there a way to determine if an application is 32-bit or 64-bit? To be more precise, I want to be able to determine if a 32-bit application is emulated under WOW64. I am using the function call library and selecting IsWOW64Process in Kernel32.dll file, but I can't seem to make it work. I think I can be implemented to false. I use a builder nodes and invoke for the process and after you call GetProcesses in the invoke node, I send you in a loop to inspect each process separately. Inside the loop is where I am using the function call library. What I read IsWOW64Process has a handle as a starter and a pointer to a Boolean value as output. I may be incorrect in what I saw several varieties of this appeal on the internet. I tried to set this up, but I can't seem to make it work. I'm looking for help on how to correctly use the library call or if someone knows a better way to do it, I'm open to suggestions. Thanks for any help.

    Thanks for the tips of Josh. The link that you sent me was, in fact, where I got the idea of what I'm trying to do. I figured out how to determine if an application is emulated this morning after further research and trial and error. I finally understand mine, but I appreciate all those who have tried to help.

  • Is there a way to determine the representation of a digital control through the property?

    All,

    It is perhaps a silly question.  Is there a way to determine the representation of a digital control of its reference?  For example, U8 vs DBL. I want to fill in the data of a file to a vi and then run it.  I can't seam to find the property that I need.

    Thank you

    Hi rich,

    You should find this property where all others are found

  • Manual large editions with sensitive html setting. Is there a way to determine how the entries appear in the table of contents?

    I publish major textbooks with sensitive html setting. Is there a way to determine how the entries appear in the table of contents? If I publish a small section of the manual then 2nd level entries appear as eruptions under the chapter name, but if I publish the manual in its entirety then level 2 headings are not at all. I would like them to appear as the eruptions in the table of contents, but I need to publish the manual as a whole in order to keep the cross references. Any help will be greatly appreciated!

    I think that this would make clearer - and it would skip and tables of contents of books under.

    Yes, your MacBook accepts two RAM sticks of 4 GB, 8 GB total, you'd better update the firmware Version MB51.007D.B03.

  • Is there a way to determine exactly where a breakpoint?

    Hello all: I can't get my head around this problem I have, so I hope that someone here is facing something like this and has a tip for me.

    I have a PXI-7354 I use for the control of gear to a rotating floor that has an encoder of lpr 8000 and a 10:1 reduction, so I 80 000 lpr effectively.

    I use the 7354 to generate a pulse of breakpoint each 100 encoder account, so I should get 800 pulses per revolution.  (I use breakpoint impulses to trigger a second device and aPXIe-5122 acquisition card data to synchronize the production and acquisition of a data record.)

    However, and here is the problem:

    When I turn at 1 lap, I see 799 impulses

    When I turn at 2 laps, I see impulses of 1598

    When I turn to 3 rounds, I see impulses of 2397

    etc.

    I'm losing 1 pulse per turn. I did not understand this yet, because I use the periodic breakpoints with a whole number of breakpoints as a period.

    The problem is that I have to "count" the number of pulses of breakpoint I receive in order to calculate the angular position, where the breakpoint occurs.  By example, if I start at 0 degrees, and I have 0.45 degree spacing between breakpoints, after 10 pulses, I should be at 4.05 degrees.  After 100 impulses, I should be at 44.55 degrees.

    As Miss an indictment by rev, however my derived angular position is incorrect.

    I need a way to determine the actual each breakpoint location.  The most obvious way to do this is to use the functionality of capture of HS of the Board of Directors, and I was able to share (yet) the pulse of breakpoint at the entrance to Capture HS on motion capture HS to map, but is possible to do internally on the 7354?

    Thank you to look at it, any help is appreciated.

    Wes

    The problem is solved, but the solution wasn't crazy direct, so I'll write my lessons leared here:

    Short version:

    I was looking for a way to make a Capture of HS at the same time that the generation of BP.  It is redundant since the ERA really only occur anywhere where tell you them to occur.

    Between the development of the servo-drive and parameters of BP in MAX, we were generating less need BP pulse at the end of the movement.  Once the disk has been defined so that the excess is less than the readjusted BP 'window', the BSP has started to behave perfectly.

    The disc has been adjusted so that it is just this side of "excessive".  I then called the amount of overtaking I see normally, and in the settings 'Compare and beneficiaries' MAX for my 7350, I put breakpoints Position 'Window' to a value that was comfortably longer than this overrun.

    Thus, the lesson learned: make sure that the servo system is set (not only at the output stage), and the configuration of BP is appropriate to your system.

    Moreover, the credit goes to Daniel to NI AE who helped me through this problem.  THANKS DANIEL!

  • Is there a way to determine the equivalent ANSI C code of a Labview project?

    I'm a complete newbie to Labview.  I have this quite complex Labview project that was used to create a DLL that matlab may call to order my card PCI-6534 without having to know NIDAQmx calls.

    I am trying to find how to make these calls directly from Matlab NIDAQmx, but I do not get the same results when I call this DLL mentioned above, so I thought I would try to give a sense Labview projects live I begins to make sense of the general economy of the screw, but I would like to be able to run the project , step through it and perhaps see NIDAQmx orders (or something equivalent, so I can determine how to call NIDAQmx commands in Matlab).

    Is this possible to do?

    Thank you

    Jason

    Yes. The toolbar allows you to turn on highlighting so that you can run the VI and see the content of the son. You can put sensors on the wires. You can single-step through the code. This is explained in the help of LabVIEW under Fundamantals-> running and debugging screw-> Concepts-> Debugging Techniques.

    In what the question implied in the title of your message, don't you can directly convert LabVIEW C code in the development environment. Yes, there are tools to convert LabVIEW in C, but which is intended for microprocessors.

  • Is there a way to determine the pixel size of type displayed in the browser?

    I'm always struggling with is type of line break, as I see it in Dreamweaver.

    "Actual size" in Safari, the type is bigger that I see it in Dreamweaver. I determined that 12px is the proper size, while work in Dreamweaver, but when I find the text online, it is much larger and line breaks do not fall where the author wants well to them.

    Here is the page in question:

    http://www.kgngroup.NET/logos_and_packaging.html

    I guess I'm wondering first, if there is a "sizeometer" that allows to identify real type pixel size as it appears, I can't say how much more it is actually what I am trying to build.

    TIA,

    Ken

    You can download a very popular plugin for Firefox called "Firebug". With this tool, you can inspect the items and view CSS properties on each. On the right side of Firebug, there is a tab for the values calculated , which will show you exactly what you are looking for, the extent of px of the text in question.

    That said, trying to nail line breaks in an HTML document is like nailing jelly to a wall. Users can (and do) change their font size in their browsers. You should address web design so that it accommodates various screen sizes, sizes of police and browsers. What you offer to your customer is literally impossible how you are trying to do.

  • Is there a way to determine the current amount of data collected using CounterReader and AsyncCallback?

    I collect a quadrupole encoder using CounterReader and AsyncCallback.  At any time, I would like to know how much value is currently stored/collected before receiving the AsyncCallback and calling EndReadMultiSampleDouble.

    Hi MYR.

    If I understand what you're asking, you should try the DaqStream.AvailableSamplesPerChannel property:

    If you perform a task of counter entry in the buffer, then this property can be used to query the number of samples available in the input buffer that have not yet been read in the application memory.

  • Is there a way to allow users to disconnect their sessions on a remote server to the RDP from their local machine?

    QWINSTA and other command line utilities are a bit too complicated for the end users, we of course do not disconnect the session hurt accidentally. In general, we only questions with sessions stuck to a few users who would be perfect if utilities command-line integrated for rdp sessions would allow to change username, but since they require a dynamic session id # I don't know how this could be scripted. Is there a tool available for Windows 7 clients on a Server 2008 RDP allowing them to disconnect from their own session if they are blocked? We have enrolled in different time zones who have to connect remotely in order to do their job and sometimes it is too early here for someone to be there to help.

    I found a http://www.ctrl-alt-del.com.au/ , but it says it is only for Server 2003 and I tried and got an error flashed too quickly to be read.

  • AFTER the last update, is there a way to always have the newtab = about: Home? (NO tiles and NOT a blank page!)

    Just refreshed and now have the format 'tab' implementation... but I don't like!

    I get the concept of any 'tiles', but can I please go back to opening a NewTab directly to about: Home? I'm a shortcut junkie, and have to open a new tab, and then select the tile is going to be a pain.

    And before ask you, YES, I already made the topic: config changes manually and YES, I have check that it still shows the value of newtab = about: House.

    Help!

    41 of Firefox, the pref browser.newtab.url doesn't work anymore.

    This is for security reasons: too many modules and malware use this feature to set their own new tab URL.

    Now, you have to use this add-on: new tab override

  • Is there a way to the Windows RT camera to youtube live stream?

    Windows rt sucks a bit in the fact that you can download apps from the app store. Y at - it's going to be a update or difficulty? I want to stream video from my laptop on youtube but I can't download any encoders. If I can't I'll probably return the notebook or sell it on eBay.

    Thank you

    The RT feature uses a cell phone processor, that's why the battery lasts so long.  Your cell phone can not run Media Encoders :)

    Looks like you bought the wrong thing.
