Building dll with front panel

Hi all,
do you know, can i build with LV Builder dll that will run with Front Panel open when i call it from some another VI?
I tried build it, but not succesfully.
The prolem was that if i select in VI properties "Show FP when loaded", dll runs with FP open, but property "Show FP when called" doesn't give same results. Dll runs, but in background.

Nadav,
Did you see this recent post about LabVIEW calling LabVIEW DLLs?

    You may tell us more information about your mainboard, please give us the detailed name of your mainboard. :D  Then there will be more users could give some suggestions.
    Sorry, there aren't that many K9N boards out there, but mine is the K9N Platinum MS7250 Version 1.0.  It's the AM2 non-SLI nVidia nForce 570 Chipset model.
    Thanks for any help.

  • Building DLLs with Returntype as string

    Is it possible to pass strings to a function and get a return type as a string.
    Actually iam facing a issue ,
    I have built a VI with Input and output as strings,the VI is working correctly
    when the dll for that VI,
    Function prototype is always void and output is always passed as a reference parameter to the function.

    Hi,
    Building DLLs in LabVIEW is described in this tutorial.  
    Mathscript can call shared libraries such as DLLs, however make sure
    that they are compliant with the supported data types as stated here in
    this help page.  All supported functions for calling/loading shared libraries is described here. 
    Note that these functions are not supported with the base package.  The
    details of the sytax of each function is described in their specific
    help page.
    Hope this helps!

  • Any 5.1 Soundcard with Front Panel working under Win 7 64?

    Since i'm finally fed up with my X-Fi Platinum not working in Win7 64 i would like to buy something else.
    Sadly Creative seems to be the only firm producing soundcards that can have a simultanious stereo output via the front panel while having he 5.1 setup connected at the back.
    So as much as i would like to stick it to Creative. But do they have anything with a frontpanel like the Titanium but working under Win7 64?

    Hi,
    What driver version are you using now? The one that's on the install CD that's included with the soundcard or the latest driver that's available via Creative Labs download service? Provide more info, otherwise no-one can help you. Anyway, the X-fi Platinum (including the Platinum drive bay) should work in Windows 7 x86 and x64.
    Try downloading and installing Daniel_K unofficial driver packs for the X-fi and see which one works the best for you.
    Daniel_K unofficial driver pack SB X-Fi Series Support Pack 2.5 (10/25/2011)
    Daniel_K unofficial driver pack SB X-Fi Series AuzenUAA Pack 1.8 (10/25/2011)
    Daniel_K unofficial driver pack SB X-Fi Series AuzenWDM Pack 1.8 (10/25/201​1)
    Uninstall the old X-fi drivers first and then use "Driver Sweeper" in Windows Safe mode to wipe X-fi drivers that are still left in the Windows OS. Make sure you create a restore point in Windows 7 first, so you can roll-back if something goes wrong.
    Good luck!

  • Trouble with front panel adapto

    Hi, I have a Sound Blaster Audigy (SB0090) and my front panel were connected to the motherboard because of the on-board sound card. I disconnected it from the mobo and reconnected it right in the sound card (it's the male connector from this picture: http://www.frontx.com/cpx57p2.gif). Ok, now that it's plugged in, my sound works perfect except that when I connect my headphones in the front panel, the sound keeps going to the speakers and not the headphones.
    I'd like some help with this issue. Thanks.

    KingAlex,
    There has been a lot of discussion about connecting SoundBlaster cards to the front case. A search of the forums for e.g., "front panel headphones" will bring up a long list of messages. This thread will get you started. I don't recommend any of the hacks because if done improperly, they might damage your card. The simplest and safest method is to plug into the rear LineOut/Headphone jack and route this inside the case to the front panel through an unused open card slot. Use a stereo Y-splitter if you also want to connect speakers.

  • HP Pavillion HPE-510f, Windows 7, 64 bit with front panel A/V RCA inputs

    When i connect devices thru the AV inputs on the front panel, I cannot find an application that recognizes the device. For example, JVC Camcorder so i can playback or just playing music thru these inputs.  Is there  a driver that needs installling?

    Hi Hodgewaco,
    As indicated in the title, the front A/V RCA and s-video are input ports.  To use those ports with your videocam you are going to need a capture program.  ROXIO has commercial programs that should work with those input ports but check with ROXIO Sales.  Usually ROXIO has a 30 trial period so if you are not satisfied the your can get a refund.  Be sure to inform ROXIO about the exact model of camera that you are using, the output connection type and the format of the video stream.

  • Problem with front panel USB connector

    Motherboard: MS-6750
    I have a problem with my front panel USB connector JUSB2 not working.
    I have checked the connection to be sure that it is oriented correctly.
    I also made sure that it was enabled in the BIOS.
    Still no luck.  There is not any voltage on this either.
    I see a jumper or pin labeled JGS1 just below the JDLED1...do not know what this is and cannot find it in the manual.
    Any ideas on what this is and how I might trouble shoot the USB connector?

    Which 6570 MB do you have, if its the K7N2 Delta 2 Platinum and came with the Dled bracket try plugging that into that port on the mainboard  and see if those usb ports work as it could be the usb hub itself not working on the front. Hope this helps  Dok

  • Audigy SE: Possibility to connect with front panel audio in/

    I have a case which has an audio in and out jack on the frontcase. Is it possible to connect these with an connector on the Audigy SE?

    Quote from: msiAMD6400 on 25-December-07, 21:57:43
    My "disable front panel detection" is unchecked.
    It is not clear to me if you were able to check (enable) the box. The setting you need is "disable front panel detection" checked; that means the motherboard delivers the output to front panel, irrespective of there is a headphone connected or not.
    If you are unable to check that box, i am not sure where is the problem. If you can, i expect you see a pop up window asking you what you have connected to the front panel, by default it should be an audio output option like headphone. Make sure, as I mentioned already, that you can see inside the audio software window the status of all the audio input/output sockets in different colours. The 2 icons representing the frontpanel should be highlighted and you should be able to designate what output/input you want from each of them. If this doesn't happen there is no point in connecting the audio out cable to the header (unless you have the appropriate MSI frontpanel cable which provides jack detection)
    If you have successfully disabled the detection, you just need 3 wires to get output (things work when they are simple). Forget about the looping; you don't need them if jack detection is disabled.
    I suggest you connect the 3 wires to the pins as shown in the manual.
    Note the pin configuration diagram for the "JAUD1" header. I think the common/ground wire from your headphone socket should be  to pin 2, Right out to pin 5 and left out to pin 9.
    Let us know of your results.

  • Can't remove Front Panels in Application Builder

    I have had a few issues using Application Builder (v7.1) in regards to it removing or not removing front panels for my subvi's when I was trying to compile. Here are the conclusions I came to if anyone else runs into the problems I had.
    Problem 1) Some of the front panels were being removed for dynamically loaded VI's, which were not set as dynamic VI's in the Application Builder, but which were static-linked VI's in the program (so they were loaded in memory as linked subvi's but called dynamically). When the Application Builder decided to remove the front panel for those VI's, there was an error when loading them dynamically.
    Problem 2) Some of the front panels were NOT being removed for subvi's that I didn't want to have their front panel built into the compiled program. Loading front panels that are not needed uses extra memory, but there was no way to change the option to not load the front panel for certain particular subvi's in Application Builder--the option was grayed out.
    For problem 1, I decided not to worry about linking the files dynamically in the Application Builder, but to just make sure the Application Builder would include their front panels. For problem 2, I had to figure out what was making Application Builder force the front panels to be included when I deemed it unnecessary, so that I could fix them not to be included. Basically then, going through my VI's that were forcibly included, I came up with a list of stuff I began checking for each time I would run into one where I didn't want to include the front panel. I have attached my list to this post.
    My solution for problem 1 was then to use a customized appearance for my static-linked / dynamically loaded VI's, and disable the menu bar (forces the front panel to be included by Application Builder without changing appearance, since I never actually see the FP). My solution for problem 2 was often to remove property nodes referencing text on the front panel controls. Sometimes I was able to perform a numeric->text or enum->text conversion instead of referencing the text of the control itself, and sometimes I realized I didn't want anything to change and that it was ok to include the front panel so I could (for example) get a list of strings for my enum control.
    I have attached the reference list I came up with of things to check for to make sure your VI properties are set correctly if you are trying to get Application Builder NOT to include the front panel of your subvi. The list might not be complete, but it's helped me to narrow down things very quickly and find the problems I was having.

    This is expected behaviour. The application has no way of knowing that these VIs will at some time be called dynamically. That would require analysing and understanding the entire program and in cases where you calculate the dynamic VI to be called at runtime it still wouldn't be feasable to do so.

    There are several reasons why a front panel is needed. One of them is when the VI is called dynamically, even if the FP is never displayed and AppBuilder will account for that for VIs which have been added as dynamic VI to the project.
    The other is when a VI uses some Property Nodes or Attribute Nodes as they are called now.
    So to solve your problem 1) you could also just drop some property node in the diagram of such VIs and be done with it.

  • Building DLLs from VIs with array as output

    Is there any special way to build DLLs from VIs having arrays as outputs. Suppose I have a VI "Random" with input "nrand" and output an array "the_random2". When I build DLL from the VI, I have something like this in my header file
    void __stdcall Random(long nrand, double the_random2[]);
    Now it returns void. So I have to pass the array as pointer and retrieve it. If I use Mathscript to load the DLL and call this function, how do I pass the pointer to the array "the_random2"? Simply speaking, any useful method to build DLLs with array outputs and the right way to call them from Mathscript would be appreciated.

  • Using Front Panel Composite Video 2 RCA Jack on the HP m8000 Media Center PC

    I have a HP M8000 Computer with front panel RCA jacks, composite video 2 and Left and Right Audio RCA jacks.  I have been unable to determine how to select  these jacks for inputting video recordings to the computer.  Any ideas on how to use these jacks to input video from my VCR?

    The front composite video jacks did not have software support for the release of this PC.  The analog video software was not compatible with Windoze-Vista so there was no software given with this PC model that supported analog video input.

    Hello everybody,
    I'm building a

    series analysis), so I'm trying to build DLLs with the .VIs I need. I
    followed all the steps necesary and visited all the related topics at

  • Connect a front panel hea

    I have audio jacks on the front of my computer case with a cable that says HD Audio and AC '97.

    I have the Xi-Fi Xtreme Gamer Fatality Pro.
    Wow... so I've done some searching and it appears this card does not come with front panel connectors, but the cheaper Xtreme Gamer card does. Is this true?
    I don't want to have to mod any cables... just plug and play.

    Yes it does,

    The one labelled "Creative proprietary connector" is the same as the one shown on this Audigy 2 ZS,

  • Front Panel Dilemma

    I am using Run VI invoke node to run a VI that is reentrant and for passing a single paramter to the same I am using set control node. Now the calling VI will be an exe when packaged and needs to run as an NT service wherein I am not allowed to use any UIs. The set control would not work otherwise is what I presume -I mean without a front panel being loaded for the called VI. Please assist in finding a work around or correcting me if I am wrong in my assumption.

    You have to leave the panel in the application as otherwise you won't
    even be able to open and run the VI.

    Yes leave the frontpanel in the build, open inside the VI as soon as
    possible a VI refnum and you can even set Frontpanel.Open of that refnum
    to False to make sure it is
    really invisible. Keep the VI refnum open
    inside a shift register until you are ready to shutdown, but don't close
    the VI refnum until after you have properly disposed any other possible
    resources. Once the internal VI refnum is gone while no front panel is
    visible, (it must be present in the built nevertheless for VI server to
    be able to start it up as independant task), your VI will abort
    immediately even if the diagram still contains code to execute to close
    files, VISA resources, etc.

    One more reasone to NOT remove the front panel. If you remove the
    frontpanel you can't use methods
    such as Set Control Value to manipulate
    the control value as it is really not present at all.
