Context between taskflows not connected event

I have a use case where I need pass information (string values) between two tasks without link-flow and regions that I use as a producer and consumer are also not part of the same page. I looked into the details of context event, but if I am not mistaken the context event cannot meet this goal. I just want to know if I'm there?

Also is there a way in the ADF for this information.

Thank you!

I was able to use the query scope simply to transmit information between the Taskflows which were not linked by a control flow. As I said the new Page/Taskflow was generated in a new tab by program and request scope was sufficient to transmit the information of the progress of a task to another.

    2. This error occurs on a specific user account?
    3. You did a significant hardware or software change before this problem?
    4. What security software do you use?

    This conflict may have been caused by some programs launched during the startup process of Windows 7 with the services.

    I played the system restore. Solved the problem, but why did it happen?

  • Some controls in the container not connected automatically

    Does anyone know why teststand is unable to connect automatically some components of a container?

    Take a look at the image as an attachment: in the configuration of the station, some areas, such as ProberPort to connect automatically, but others, like WetTestHardwareDAQID_1, do not connect.  If you look at the settings, you will see that the two containers (container TestStand and the cluster of VI output) are similar.  So, why the? .

    S G

    You get the message as a mapping between elements of cluster and the subproperties of the parameter is not found.  To check this, go to the definition of the type of the variable StationConfiguration.  In the type definition, right-click and select properties from the context menu.  Select the Cluster tab by the way.  In the drop-down list box, select the WetTestHardwareDAQID_1 and see what is the value of the control 'Cluster Label element.  If it is empty, then there are no specified mapping.  Do the same for WetTestHardwareDAQID_2.  To add a mapping, simply enter the element of cluster label that you want to map the property.

    A possible reason for the 'Cluster Label élément' control is empty, it is that someone has made a change to type on these subproperties.  Note that the type column has a button to change the type of the subproperties.  If you click on the button and select a new type, the cluster by the way the information is lost.  It's something we know and will be fixed in a future version of TestStand.

  • Could not connect to the service user profile Service.

    I have a little disconcerting problem.  Every day or two, I can not connect to Windows correctly.  When I start, select my account (which is also the unique administrator account) and enter my password, it spends an abnormally long time in the 'Starting Windows' screen, then I get the following message pop up in the notification area:

    "Unable to connect to a windows service.
    Windows could not connect to the service user profile Service.
    This problem prevents limited users to logon to the system.
    As an administrator, you can review... »

    Shortly after this message, I get a windows error message saying:

    "Location is not available.
    C:\Windows\system32\config\systemprofile\Desktop is not accessible.
    Access is denied. »

    This seems just a desktop computer black with only the Recycle bin icon on it, and the old Windows Start button in the taskbar.

    While trying to understand what is happening, I looked into the application of 'Problem reports and solution' in the control panel and found that every time this happens, I also have a corresponding event of "Stopped working" "Routing and remote access.

    I then restart using F8 at startup and choose the one that says something to the effect of "using the last good configuration known."

    I'm not sure what that means at all, but I hope that one of you people can help.

    Thank you!

    Hello any Leafs fan,

    Thanks for posting on the Microsoft answers Forum.

    Looks like you're running only because of using a system restore to get back when your system is running. Now, you want to know what caused it.

    Usually, when the above error occurs, it is due to a corrupt user profile.
    The best way to fix this is to remove the user profile.

    • Go to the Start button
    • Right click on computer
    • Go to the properties
    • Go to Advanced System Properties on the left pane
    • Select the Advanced tab
    • Go to the user profile Section and click on the settings button
    • Find the profile for the that you want to remove and click Remove.  (It's the best way to remove the local profile in Windows Vista).
    • Connection again and you will get a new profile.
    • To get your Favorites return, go to the old profile in C:\users and copy the data manually.

    The only way to identify what caused the error with the user profile is to try to reproduce it.

    If you have not installed the update of Windows, then you can go to Windows updates and see what are the updates must be installed and manually download them and install them one at a time. Between the installation of the system, make sure you have a restore point that you can go back to if necessary. Once an update is installed, then close and open a session back (or reboot if required by the software update) and see if you get the error user profile. If the error occurs, then go to Services and see if the user profile service is running and set to automatic.

    If you are not able to do anything when the problem occurs, then try to start in safe mode using the F8 key and see if the problem occurs in safe mode.

    You can also look in the event viewer to see if there is no dealing with event profile user or Windows Update errors.
    To get to the event viewer, you can type in eventvwr.msc in the box start the search. This will bring up the event viewer and you can view the summary logs and see what kind of errors you encounter.

    Please post with your results and if you need further assistance.

  • This cable or accessory is not certified popup while not connected iOS 9.3.4

    I've updated to 9.3.4 iOS on my iPhone 6 more this morning. Now, this afternoon, I get a popup every few minutes saying "this cable or accessory is not certified and may not work reliably with this iPhone." I'm not connected to a cable or accessory. Support Apple advises to do a hard reset, which I did. After a few minutes I received once again the context menu. Not plugged into anything.

    Never received that message before today. The only thing I know that has changed is the software update 9.3.4 (G 13, 35).

    Similar experiences please mark as I have this issue too. I saw another post here, a user with an iPhone 5 with this exactly the same problem.

    Kind regards

    Charles Cavanaugh

    Hi ccphd,

    I understand that you get an error that the accessory is not certified, despite not having anything that is connected to your iPhone. I know it's important to have your device works reliably, so I am pleased to provide you with tips to help with this.

    Learn the steps of troubleshooting we have for this message here:

    If your iPhone, iPad or iPod touch won't charge - Apple Support

    If an alert says that your accessory is not taken care of or certified

    These alerts can appear for several reasons: your iOS device could have a port of loading dirty or damaged, your loading accessory is defective, damaged or not certified by Apple or your USB charger is not designed to load devices.

    1. Remove all debris from the charge on the bottom of your appliance socket.
    2. Restart your iOS device.
    3. Try another USB cable or charger.
    4. Make sure you have the latest version of iOS.
    5. Contact Apple to set up the servicesupport.

    Thank you for using communities of Apple Support, cheers!

  • I do not use sync and am not connected? Why my favorites are synchronization?

    My desktop computer has a series of bookmarks that I use at work. My home PC has another, different set of bookmarks that I use at home. I do not use sync and am not connected to sync on each PC. Why my favorites are the synchronization between two PCs? For example, I noticed several bookmarks near the top of my bookmark menu over a line of separation that I do not have to work. I deleted them. I come home and find those missing same bookmarks from my PC at home. I do not want to synchronize anything between the two computers, why what is happening?

    Maybe an add-on is the sync these for you.

  • Ink advantage 2545: changed the name of the wireless router and now ink advantage 2545 does not connect and I'm out of ideas

    I have a Toshiba laptop 64 bit running Windows 10 Home, 8 GB, 1 t hard drive.

    Router is a Samsung phone using Android because it was the only router that I could find which would take the wireless signal.

    I live very pastoral, no neighbours for miles, so I never saw the need for a password on my router.

    Now, some people are installs in less than 400 feet from me, and I think they're piggybacking on my Wifi because my access speed has slowed considerably since they moved in.

    So I decided to change the password of the router, unfortunately, I can not put in any password I want.  It gives me the opportunity to have a predefined password.  So I changed the name of the router I could do without problem.

    My computer very quickly without any problem, however, my printer which worked great for a year with the old router name does not connect on the new name of the router.

    Here is what I tried:

    I had hoped he would ask me for a new name / password, but it did not.

    Then I plugged a cable between the printer and the laptop in the hopes that it would produce a different kind of results.  It has not changed anything.  There is no screen menu on what that be like this on the printer.

    I pressed the wireless button that has the flashing blue light and nothing happened.

    I pressed the button, don't know what it is, but it has a white light, and nothing happened.

    I went on the HP site and followed the instructions but he just said do not connect the cable until told to do so.  So I disconnected everything, lights out and turned back on and still no connection and no invite to plug whatever it is.

    Y at - it everywhere where I have being a novice could get instructions on how to get this working?

    I appreciate any help you can give me.  Thank you.

    Connection failure

    'MacBook Pro' is not supported

    and the only option to close this dialog box click the device forget .

    I therefore looked on my personal Mac which had previously been paired with the phone to find that he was is no longer listed in the devices Bluetooth, but when I looked in the settings for MacID running on my Mac it says "Looking for iPhone 6 s.  I tried to re-pair 6s iPhone to my personal machine and had the same results.  When I called in my TI guru we tried with his iPhone 6 (also installed 9.3.1) and had the same results.  As it's been a few months since I used MacID on my computer that I don't know when the link has been broken - after an update iOS or OS X update.  Bluetooth linking to my Apple Watch still works perfectly.  I was unable to try this out with any other Mac, I was looking for one with an older version of Mac OS X.

    Everyone is aware of this problem or have an idea for a fix?

    TIA

    An iPhone will not pair Bluetooth with a computer (Mac or Windows) for one use other than personal hotspot and it will only do that if the carrier is supported. However, there are a number of things will be using Bluetooth between the computer and the iPhone where the devices are NOT matched. More information in Bluetooth: why can not connect my iPhone or iPad with another iOS device or my computer?

    The following link for MacID support site has instructions on how to do the installation. It requires Bluetooth to be turned on in the computer and the iPhone, but the rest of the configuration/connection is done inside the MacID app on each device, not normal Bluetooth pairing as follows: http://macid.co/help/?c=Setup & sc = Pairing % 20A % 20device

    Please disable encryption settings in the Wlan router and try to connect to the Wlan that is unprotected.
    But note; This must be done only for testing purposes!

    You should also check if the MAC address filtering is disabled in the settings of the router.
