Hi, I'm developing a application thats need read and log a large tag database at

Hi, I'm developing a application thats need read and log a large tag database at period of 1 second. My system have actually 1200 tags and when I try to increase the number of tags my system slowdown and not update at requested period anymore. I'm using NI OPC Servers to read data of 4 different PLC's. In the SVE I've created an IO Server to bind variables and all variables are located in a single process. All variables are logging alarms and data. The Log Deadband and Update Deadband are set to 0. My machine is a DELL Precision T5400 with Dual Intel Xeon Quad Core with 4GB of RAM and Windows XP Sp3 installed. Bruno Costa Automation Enginner

    Are you trying to update only that one app or more that one app (via Update all)? You have to log into the account that purchased an app to update an app. If you have apps purchased by more than one account you have to update tem one at a time until the remaining apps were purchased from one account.

    First, did you use Setup or Migration Assistant? That can happen when coming from a PowerMac or sometimes even from another (Intel) Mac.
    Second, wait for the next version of Final Cut due very soon to ship (may have to wait for the ".1" of course to clean up any early issues.

    There are a few apps that are better.  I think you can run multiple instances of Handbrake for one.

  • Is there an application that will open and view MS publisher?

    Is there an application that will open and View MS Publisher files?

    Afraid not. You can run Windows on your Mac then run Publisher in Windows. You can find out then if Publisher can export in a "standardized" format other applications might import.
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
    Install the Apple Boot Camp software.  Purchase Windows XP w/Service Pak2, Vista, or Windows 7.  Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows.  Boot Camp enables you to boot the computer into OS X or Windows.
    Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7.  Parallels is software virtualization that enables running Windows concurrently with OS X.
    VM Fusionand Windows XP, Vista Business, Vista Ultimate, or Windows 7.  VM Fusion is software virtualization that enables running Windows concurrently with OS X.
    CrossOver which enables running many Windows applications without having to install Windows.  The Windows applications can run concurrently with OS X.
    VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris.  It is not as fully developed for the Mac as Parallels and VM Fusion.
    Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. Boot Camp is only available with Leopard or Snow Leopard. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

  • Develop a program that can read pdf document in the UClinux OS?

    hello,
    I'm a programmer in a company which is doing embed development ,i want to develop a program that can read pdf document in the UClinux OS?
    Can some one give me some ideas?
    can some body give me some information?
    My email is [email protected]
    thank you!!!

    I would strongly recommend using one of the libraries that are available (Google). If you don't want to pay the (modest) costs of a commercial license, there are several open source projects with licenses that allow you to use them in commercial products.

  • Creating exe for application that contains ARINC and MIL Codes

    Hi all,
    I am not able to create exe for my application that contains ARINC and MIL. To be precise, the ARINC and MIL part is not working in the exe created. 
    Please tell me how to create an EXE with ARINC and MIL codes.

    Did you install the according device drivers on the target machine? And no I don't mean the instrument drivers that you use in LabVIEW but the OS device drivers from NI (resp. AIT), that will access the hardware boards and provide an interface to the LabVIEW application. I would expect them to be part of the AIT SDK kit that comes with the boards.

  • Video Playback Problem with Developer Walkthrough of the Continuous Measurement and Logging Sample Project

    Hi!
    I have serious problems playing the video Developer Walkthrough of the Continuous Measurement and Logging Sample Project.
    As the video pauses every few seconds for buffering. I am not able to watch it. Just wanted to check if you can playback the video:
    http://zone.ni.com/wv/app/doc/p/id/wv-3401
    This happens on any browser (chrome, ie, firefox). I am using Win XP and the latest Adobe Flash Player. About 2 weeks ago NI Germany confirmed the problem and promised to contact NI USA as they are responsible for these videos. So far nothing happened. In the meantime I received an e-mail that the problem could not be confirmed although they had confirmed it before...
    Thank you for any feedback.
    Regards,

  • Developer walkthrough fails on Continuous MEasurment and Logging

    I am having problems watching these two videos:

    Developer Walkthrough of the Continuous Measurement and Logging Sample Project
    Queued Message Handler Template Documentation

    It gets stuck at the start saying Slide 1/1: Buffering.
    I have downloaded the latest Adobe flash.  A guy from NI support rang in response to my question to them and said that it worked on Chrome for him.  I tried that and they don't work for me.
    Can anyone help?

    OK, one update from my side:
    On my machine (Win7, 64bit) it is working when running Firefox 29.
    Using IE9, the link to the video seems to lead back to its page, no popup, nothing.
    Point is, that my IE (since IE8) is obviously not 100% compatibel with Adobe Flash player. For instance, i have issues to play videos from YouTube on the machine using IE (error messages like Flash not installed or simply a blank screen instead of the video) but not for all videos there. With Firefox, i can view all videos from YouTube except the ones which are prohibited from YouTube due to national restrictions ("This video is forbidden in your country" or something like that).
    So all in all, it seems to me that the issues you all observe are issues between the browsers and Flash, invalid settings for popup-blockers and specific "error handling" of specific browsers (which create the "loop-link-behavior").

  • Any software/program that can read audit log files

    Hi,
    Currently i am searching for a program/tools that can read audit log files and format it into a readable format. Anyone know is there any in the market or any open source program?
    Thank You.

    Not sure what you mean by "audit log".
    Anyway. Pete Finnigan's tools page has only one thing that might be what you're looking for - LMON, which runs on BSD, Solaris, Linux. As he's the go-to guy for Oracle security the chances of there being a good free log analyzer tool that he hasn't heard of is slight.

  • Federated authentication application that also reads Forms cookie

    At our company we are planning to move our IIS applications from forms based authentication to federated authentication. We want to move one application first (big bang is difficult). All applications currently share a forms cookie (in the same domain,
    same IIS server). I am looking for a way to move one application to federated authentication while still supporting users that are logged in with forms authentication.
    I am thinking about the following scenario's:
    IIS application 'A' has federated authentication configured (ADFS)
    IIS application 'B' has forms authentication.
    User request page in iis app 'A'   -> authentication mechanism checks if a forms cookie from app 'B' exists. (form cookie exists because user has already logged in via username/password webform in app 'B')
    If yes, the info in this cookie is used to build a valid claim (custom code), federated cookie is set with  this claim.  User session can start 
    If no, claim is obtained via ADFS server, federated cookie is set with claim. User can start session.
    In this way, users that are authenticated via Forms authenticated are supported in an application that is configured for ADFS claims. That gives us the possibility to gradually move all users from our custom security system (based on .net forms) to AD.
    How can this be done?
    Bert-Jan

    The legacy forms logon (non-federated) with the cookie is independent of the federated logon process. You can always stand-up a separate IIS website (federated) to point to your application in a side-by-side capacity, thereby meeting the requirement for
    federated logon (assuming the application supports that) and legacy forms, but crossing trust boundaries between the legacy and federated logon for SSO purposes is not possible OOTB. If you want AD FS to issue claims from the "classic" forms logon
    alternate, then that forms logon provider would need to also be a trusted claims provider and possess its own Security Token Service. In general I try, and emphasis on the word try ;-), to shy away from customizing AD FS logon screens, primarily because it
    can come back and bite you. While AD FS 2.0 provided some latitude for these sorts of practices, AD FS 3.0 (and beyond) does not ...

  • Application that sets up and starts internet sharing

    I'm new to OS X programming and was hoping to get some ideas in solving a problem i'm having.
    Need to create an application that will set up internet sharing with specific configurations (Firewire and airport only) and then start it.
    I have been playing around with applescript to automate the gui controls of System Preferences and it works pretty good. However its very annoying that the gui needs to be displayed to do this.
    MS provides an API called INetSharingConfiguration that enables network connection bridging in visual studio. http://msdn.microsoft.com/en-us/library/aa365935(VS.85).aspx I would be surprised if apple did not provide something of the same, however I have not been able to find it.
    Does anyone have knowledge of a framework or API that could be used in xcode to get the same thing done? Suggestions would also be helpful.
    Also, If I have to stay with applescripting the gui controls, is there a way to hide the gui when this is activated?

    still looking for a good solution but I did come across a plist file that seems to hold these settings. /Preferences/SystemConfiguration/com.apple.nat.plist
    Has anyone successfully modified this file and started internet sharing by using it?
