OPC materials - end user adding a new devices

I need to create an application that connects to a compatible device OPC and read labels (variable) in my program.  I can do this by creating a shared variable.  What I have to do is to add other devices.  It seems obvious that all devices have the same tag name.  When the program runs, my client would like the opportunity to select one or more devices to read/write data to.  What the program is really intended for the registration of data using the Citadel, set up alarms, graphical representation, report generation, etc. and will make good use of the DSC module.  The way I imagined the work programme is the user to press a button to add mutual FUNDS to the program, a dialog box appears with all available OPC devices, the user selects one and hits OK.  At this point, the program comes to life, recording and graphic representation of data, generate alarms etc.

What I see what will happen, is that when a device is selected, a table group is populated. Each item is a separate device, and every table is a separate variable.  Ex:

Hello

To bind the variables programmatically you must add the server I/O first on your process, the functions srvl_load_db_es.vi and srvl_atualizar_es.vi. The function "subCreate and set IO Server.vi ' creates a new i/o server and is not documented by NOR.

To create added make variables programmatically on your srvl_atualizar_vm.vi service processes. This function makes calls to the functions of the DSC and configure all the options step by step.

To find an address mutual FUND you can use the function "Datasocket select URL.vi" or you can use a tool in the 'LogosBrowser.zip' attachment below.

  • Adding new devices to a marketed product

    Hello

    I have a product that is out on BB App World, but I want to add new devices to what my current application supports the but I didn't not sort the equipment initially when I introduced the app.

    I have to create a new version of my application and then submit for approval even if I'm not changing any code?  Or is there a different way to the list of new supported devices?

    Thank you.

    You can simply edit the existing version and add new devices, there is no need to present the new version.

    To manage the products in the supplier portal, click the view release (eye - like button ) - Edit button (pencil type) - add Version tab - do scroll through and edit Device Support (add new devices)

  • Class not found exception after adding a new image in the folder resources.

    The app works perfectly well on the Simulator and the device. After adding a new set of images, he began to show in every race, on the Simulator and the device, a class not found exception.

    When you try to delete some images to find the cause, I get different classes not found when executing. Compilation and packaging the application generate warning or error. They even get signed. Some of the classes are not exception I get:

    Java.lang.StringBuilder

    NET. RIM. Device.API.UI.UIApplication

    I'm guessing this has something to do with the size of the total image, since the size of each range image from 100 KB to 300 KB, and we talk about only 25 or 30 images in total. Adding image outside of the 'res' folder does not generate the error, but the image is not added to the final files.

    In addition, this application is not large, but when compiling and packaging of the app, it generates and signs 125 cod files. Is this normal?

    I use Eclipse 3.6 (Helios) and BB SDK 5.0.0.25 won win 7

  • Adding a new scanner Epson to Photoshop CS5.1 on computer of LION

    We have just recently (today actually) has installed a new scanner flat of Epon on an iMac MAC OS 10.7.2.  He already had Adobe Photoshop CS5.1 top.  It seems that no matter what we do, when we click on go to the import file, the scanner is not there.  I'm not an experienced user of Photoshop (or someone with experience of Mac), I'm going by what the end user tells me should be there and how its supposed to work.  It must be able to scan from the new scanner in Photoshop.  Is there documentation somewhere that tells us how to get Photoshop to 'see' the scanner.

    The computer is an iMac brand new (one month) that came with LION.  We had to replace to replace the old becsause scanner, he was not supported in LION (is supposed to be the one we just bought).

    There are scanners out there that Photoshop CS5.1 version 12.1 for Macintosh will simply recognize without any intervention by someone I.T..  Photoshop will allow scanning from the application with any scanner?  (the user thinks we should get just another scanner)

    It is important to understand that the analysis in Photoshop is not directly between Photoshop and the scanner (hardware). The whole process depends on what software to scan mediates between Photoshop and the scanner. Just Photoshop is there and waiting for the software to hand it an image. The scanner just is there and waiting for software to request a scan. So it should not be necessary to change the scanner itself. Instead, try changing the scanning software.

    When the software bundled with the scanner is not what someone wants, sometimes they turn to the software of scans from third parties. I use VueScan, which has historically run as one request separate, but has recently added the ability to be launched from Photoshop as a plug-in and return the image directly into Photoshop, just as she wants. As long as your scanner is on the supported list, this is a possible solution. But it will cost you a little money.

    VueScan is a good example of software critical how scanning. Many people use VueScan to work around the limitations of the packaged software. Sometimes they want more features that the own scanner software came with. Sometimes they need because the software provided no longer works in the latest Mac or Windows OS, so he lets people continue to operate for many years more, instead of having to buy a new old scanners.

  • y at - it end users in a place can give suggestions on the improvement of firefox?

    I was wondering if there is a place in the forum that accepts suggestions from end users who would greatly improve the use of firefox?

    My suggestion is related to the customization of the browser layout.

    It would be nice if we could put "breaks" in the bars going across the top and bottom,  so that when we add one of the shortcut icons, they don't all bunch up on the left side of the browser.
    

    For example put privacy related icons on the left, all the navigation icons in the Middle, and all the icons on the right side cat. In this way they are not all grouped on the left is a small area.

    So it is easier to see related to the security of information while not being not distracted by chat associated icons for example who are concentrated on the right next to him.

    This is a very good example of what I mean of the VLC interface customization.
    http://www.VLC-Player-download.com/VLC/interface-customization.html

    Note the "<>-" having said space put here between the control icons.

    Maybe it's all what you need is a square that is empty without an icon that can be placed on several occasions to give the user control is how much space between the control icons.

    I think that doing it this way would be to minimize the necessary coding is what I guess you need the new block of part blank icon "repetitive".
    Letter O is the white block the other letter first lefter control icon.
    Example: S-A-G-O-O-O-O-O-O-D-T-O-O-O-O-O-C-V-R
    see how the letters of control are now spaced with empty "O" between the two?
    Now, when I'm looking at the security related control icons on the left I have not D, T, C, V, R distract me from S, A, G.

    enough said
    frugal

    In the old days, there were separators and flexible spaces (used to separate the icons aligned to the right and left, not sure about centering), but Firefox 29 and above do not have those.

    Users who need those back could now try the customizer of UI multi-purpose Classic theme restaurant owner (https://addons.mozilla.org/firefox/ad.../classicthemerestorer/). It might be overkill, however.

  • When you try to add a new device, on access to tools, Options, Sync tab, no manage an account or add a device link button. I can get codes displayed to appear on another device but cannot access a screen that I can enter the codes.

    When you go to the tab sync, I see nothing like the picture in the help pages that show a button manage an account and Add link device. I think I need to access the device link add to reach a screen that I can enter codes to set up the easy way sync. I have already overcome the problem of connection and enter my key synchronization but it's more effort and it seems to me that adding new devices does not work as described. I'm on a Win7 PC and a laptop Windows XP using Firefox 5 and using Firefox Home on an iPod Touch. I have not found a way to get into the 3 codes of four characters shown on my Win7PC on one of the other devices.

    Hello!

    If you have an account, but it seems that you are not logged in. Please, follow these steps:

    -Go to your tab sync in the Options window.
    -Press «Set up Firefox Sync»
    -Press half 'connect' down.
    -Select "I don't have the camera with me.
    -Now enter your contact information, including your sync key. And you're ready to go.
    -If you have lost your sync key, select the option below "I have lost my other device" and follow the instructions.

    I hope that this information resolves your issue.

  • RN104 - added 4 new 4 TB drives. 2.5 days of resynchronization. Start copying files, or wait until it's done?

    I think I've drunk mostly in the title...

    I just added four new 4TB discs (WD40EFRX) to a vacuum RN104 running the latest operating system. (6.4.0)

    At the start, he started a resynchronization estimated at about 70 hours.

    Is a resynchronization required on an empty set of disks? (If not, can I cancel?)

    If I have to re-sync, can I go ahead and start writing some stuff on the drive is Resyncing? (I'm willing to take whatever the performance hit, there could be.)

    Thank you!

    The synchronization is made at the level of the block of readers, even thoug hthey are empty, they still need to be resynced.

    If it's critical to copy the data across, you can start adding data while resynchronization is in progress. Although you will take a significant performance hit, synchronization and the writing speed. AND, you won't have the advantage of reduncancy until the end of the resynchronization.

    Unless it's critical data, my suggestion would be to wait until the Resync is finished, and THEN copy the data across.

  • Critical failure DirectX - DXDiag shows no problem, used for end-user TIME, nothing works.

    Without apparent reason, Direct X has suddenly stopped working. I can't play Solitaire or the Sims 2. I followed the previous advice on this issue, and with the help of dxdiag shows no problem, reinstall he didn't help not, using the runtime for the end-user to install thing older DX 9 stuff told me that everything is up to date, I am at a total loss.

    I am running Win 7 Home Premium and everything I have running is Firefox, GIMP, and Skype. I searched for nothing 'media center' as I've heard it's a question and nothing like running. I don't know what to do.

    There are two DirectX install 'things'.

    It looks like you were using the Installer Web of DirectX, which is an update of DirectX.

    The update only installs the DirectX 'missing' files and does not overwrite the existing DirectX files.

    which is what is needed if a DirectX file or files is damaged.

    -It may be that your error is the result of corrupted files. It happens from time to time. Sometimes because

    a game or other software borks DX format when it insists on the installation of DX again for you.

    The DirectX Redist (June 2010) below to replace all DirectX files.

    When you run the installer it will ask you where you want to save the downloaded installation program then

    "unpacks" the installation of DirectX in the selected folder.

    After unpacking, open that folder and locate the DXSETUP.exe. This will reinstall DirectX, and

    should at least eliminate corrupt files DX as the source of the error.

    (You can delete the installation folder after installation).

    I want to move my old 8900 MyCast Weather on my new 9550 but App World will not produce a new license code and continues to fed the former.  I followed the procedure below has been proposed by Garmin several times and installed, reinstalled, deleted, battery pulls and everything I can think of and nothing works.    Sure would appreciate any suggestions.

    The user goes to a new BlackBerry:

    If the user tries to download App World for the new device and newspapers by virtue
    their PayPal account, you can reinstall each element individually.
    Once installed, the status changes to "installed".  If the user had
    free trial / elements on the previous device, they have to redownload them
    Once again.

    If the status of an item appears as "Not available for this device", the
    point is not compatible with this model of BlackBerry.  If it turns
    available for this device later, the status changes to "uninstalled".
    and it can then be put back.

    The license key will be different for the new device because the PIN on
    the device is different.  The new key is located in the App World of
    choose My-Cast Weather since My World tab.

    Got a new Garmin code that has worked.   Really appreciate the good service from them.   Hopefully RIM will correct the problem with AppWorld soon.   Thanks again for the help.
