• Impossible to get Graph.DataSource to work in WPF, I (thread question?)

  My chart is work beautifly when I use:

  chartCollection.Append (measure. GHz, measurement.dB);

  But when I try to use this call to the same method, I get nothing on the graph:

  Double data = new double [256];
  
  ....
  
  Graph DataSource = data;

  I know not if there is a suspicion, but I declare chartCollection on the main thread, and then pass it on to a different thread to collect data and it draw in real time.

  I could have lived with chartCollection.Append but in this case, I got a lot of data instanteneusly and I want to assign to chart at a time.

  Moreover, it seems that you need about 350 ms differ between each card. Add to not cause exception... but in my case I need to delay in all cases (for data) is not a problem.

  Thank you!

  I'm not very clear on how you mix the table/matrix updates. Here is an example of chart queue adds via the dispatcher (using a class task and assistance as a quick way to simulate the substantive work). You can use any delegate with the dispatcher, so you can assign DataSource in a delegate instead of use the method append on a collection of table.

  public partial class MainWindow : Window {
        private readonly ChartCollection chart = new ChartCollection( );

  public MainWindow( ) {
            InitializeComponent( );

  this.graph.DataSource = chart;

  var worker = new Worker( this.Dispatcher, chart.Append );
            Task.Factory.StartNew( worker.DoWork );
        }

  private class Worker {
            private readonly Dispatcher dispatcher;
            private readonly Action append;

  public Worker( Dispatcher dispatcher, Action append ) {
                this.dispatcher = dispatcher;
                this.append = append;
            }

  public void DoWork( ) {
                for( int i = 0; i <= 360;="" ++i="" )="">
                    double value = Math.Sin( i * Math.PI / 180 );
                    this.dispatcher.BeginInvoke( this.append, i, value );
                    Thread.Sleep( 100 );
                }
            }
        }
    }

• simple thread question

  Hello world

  My question is quite simple.  I have two text boxes. I wrote "123" in the first text box and 'abc' in the second area. When I put the two boxes, the content in the second box automatically flowed to the first area, because there was space in the first box. Now the first box shows "123abc", and the second box is empty.

  How to stop Indesign automatically cela. Is this possible?  I know I can do it by screwing the two boxes first then the input data, but I have already entered all my data and it save me a lot of time if I can just have screw now.   Thank you very much!

  Simon

  Until you put frames, insert a frame break in all Type > submenus insert a special character

  Then content don't flow from 1 in frame 2 frame when you put on, because you insert a frame break stops at what happens.

• Thread question: change competitor Exception

  I have a table and two threads are using it, or at least using the reference variable. We ("Reader") just reads the values of him very frequently. The other ("Reassigner") much less frequently reassign reference variable in the array to a new version of the table.
  
  What happens if a collision occurs? I think that nothing bad. Am I wrong? I don't know how model a collision and know empirical, but I don't want to deploy and found out the hard way.
  
  Consider: Reader starts to read the table, lifting the single value, that he needs. At the same time, Reassigner points the reference variable in the array to another array object. Bad? I think that the drive can read just the anonymous orphan table now and soon-to-be with no problems. Or some kind of concurrent modification exception will be thrown. Or is there a bad collision if two threads try to obtain and to reset the address of the array at the same time?
  
  Thanks for any idea.

  Jim Ryan says:

  Thus, the reader sees is not the new value for who knows how long, if ever, is not catastrophic?

  Yes. If I can't avoid this possibility otherwise, I'll have to synchronize.

  Another option that may work for you is to declare this volatile reference variable. If your only problem here is that the reader must see each write, for example, that you don't have to worry about atomicity of the actions of several steps that go with writing or reading, then declare this variable of volatile reference will ensure that each reading and writing goes against the master copy. It should be no more overload as well as in the clock (since synchronization is forced against the master copy read/write), and I expect that there is a little less (since the synchronization must obtain and release the lock, while the birds only means that we use the master copy).

  However, if your drive is iterate through the table using the shared reference variable and the writer wrote in the reference in the middle of this variable, then the drive will suddenly be reading a different table and could end up with ArrayIndexOutOfBounderException, or at the very least, data for the last part of the table that has no relation to the old part. It is a form of atomicity, that I mentioned, and it can also happen with synchronization if you don't do it right.

  A way around this would be for the reader to do something like this:

  void someMethod() {
    int[] localReference = sharedReference;
  
    for (int x : localReference) {
      do stuff
    }
  }
  

  In this way, even if the writer becomes the shared reference while the player is an iteration, the iterator won't see it during its current iteration. His localReference will see either the old value or a new, and this value will persist during the entire iteration.

• Server WRT1900AC DNS (?) Questions

  It is a separate, but related to the thread - question WRT1900AC DHCP do not distribute the specified static DNS entries

  I have not seen this documented function of anywhere, but it seems that the WRT1900AC has an internal DNS server? The router is set to dhcp clients local (front & reverse) on my local network with DNS suffix that is issued by my ISP (via external DHCP). Accordingly, it is causing conflicts on my network name resolution.

  Example: My router receives its external address via DHCP from my ISP (WebPass). The optional parameter "domain name" is not editable (see screenshot)

  

  Now, when a dhcp client internal registers on the network with a name in conflict (for example, the www host name) it will cause a DNS conflict on the LAN:

  Nslookup www.web-pass.com

  Server: 172.16.1.1

  Address: 172.16.1.1 #53

  Name:www.web-pass.com

  Address: 172.16.1.110

  where it should resolve correctly to 184.106.186.186. In addition

  Don't get me wrong, I'd like a DNS local on my router - but for it to be functional and conflict prevention, the following must be done:

  1. Allow editing of the "Domain name" field to create a distinct and not conflicting namespace.
  2. Allow the ability to add static DNS for non-dhcp clients
  3. Leave the option to disable the local DNS server, for those who use & prefer their own internal DNS server
  4. Fix the bug (DHCP/DNS) mentioned at the beginning of the wire

  If anyone has thoughts, observations, any other solution to workaround it please feel free add on this thread.

  Linksys support reached out for me and I got a call with one of its engineers (Julie Louh - which was very useful) on this subject. It also has the problem of DHCP/Static DNS (mentioned at the beginning of the original post) of design to allow the IP address of the router to resolve the site of smart wifi Linksys (Cloud / anywhere configuration). She confirmed that the router uses IP addresses is entered in the static DNS config for DNS lookups.

  On the DNS server issues described in this post, it should present the following feature requests:

  1. Allow editing of the "Domain name" field to create a distinct and not conflicting namespace.
  2. Allow the ability to add static DNS for non-dhcp clients

  Of course, these feature enhancements will move up the chain of management for approval. But I think that if these 2 are implemented it will solve the main problems described here.

  On a separate note, I was very pleased with the customer service and the reaction of Belkin/Linksys. The personal reachout to a technical support technician really shows that they are determined to make this powerful router and feature rich as they promised it would be.

• My firefox has built about 1500 toolbars of unwanted bookmarks

  I tried many methods to get rid of what uninstalling Firefox for at least 1 month, but on the resettlement, the same problem is there. I would like to continue using Firefox, but in these circumstances cannot

  What can be done to remedy the situation

  1. User.js is an optional file that is located in your profile folder. Use the help > troubleshooting information-> Application Basics - profile folder - folder show to get your profile folder. Then right click on this file as the use of open with Notepad (or Wordpad). Note: some malware create / install a user.js without the user's knowledge and it's something that we give for displaying more 'system details' that comes with a new thread questions.
  2. Unless you manually delete the profile folder when you uninstall Firefox, it will be picked up again when you re-install Firefox. You will probably have 'problems' that you had when you decided to stop using Firefox and got rid of the program to uninstall files.
  3. For sure many bookmarks in Firefox toolbar folders, you have a massive corruption of 'something' - probably the places.sqlite file where are stored favorites. We recently saw the eruption of corruption BTB threads involving Sync can involve 'mobile', which is Firefox for Android - that is why I asked to Sync 'mobile '. Synchronization treats a little differently to 'office' Firefox 'mobile' - a smart phone screen is too narrow to have a favorites like "desktop" bar / can manage screens of portable computers. And he can think that the 'problem' is with Sync, at least partially. With your mobile devices using Safari we can scratch that as a contributing factor.

  One device with what looks like the favorite file system corruption.

  Install and run the extension of Maintenance of places.

  Many times it is able to clear up a problem like that, but I don't remember not 1500 bookmarks, toolbars in being never talked before. Typical with the BTB is multiplied is less than 10 best of what I've seen posted here.

• Firefox all 31 changes PDF icons for Firefox HTML icons that I can't change it back, this is corrected? Using Windows XP...

  Once installed Firefox 31 he sees all PDFs in Firefox HTML files and all PDF icons change to Firefox HTML icons. This change may not be reversed without uninstalling Firefox.
  Only the icon is changed, not the. PDF extension.

  This can happen if there is no default application that handles PDF files.

• My category of bookmarks in the toolbar has a logo of Trojan on four of the dropdown menu items.

  I have a desktop Mac G5 with OX 10.5.8. My Safari browser has been hacked with malware of TH, and so I removed it because it is too old to update to the Mavericks.

  I am now using Firefox. I now see that the Trojan horse is rooted in my bookmarks bar, on the drop-down menu Options. I was trouble reset Firefox and I can't the Malwarebytes that I downloaded to open and run. I deleted the history, cookies, cache them on my computer. I also deleted the Java, MSN and email old, mail and setting the hard drive.

  I don't know what the Trojan horse is / was, but there were a few reports of pseudo ransomware. This requires money and creates the impression that Firefox is locked. If you're lucky and you have this kind of problem, it is easy to get out of.

• How can I stop my URL bar (upper center) to use the same search parameters such as my bar (top right) research

  I want my URL/address bar (the space upstairs in the Center) to use the google search when I type in, and I want the bar (the one top-right) research on Wikipedia, when I type in. She had previously worked like that, but suddenly firefox is no longer is allowing me to use different engines in the two areas.

  I've tried setting the keyword.url to 'http://www.google.com/search?ie=UTF-8 & oe = UTF - 8 & q =', but this setting is for some reason ignored and fails everything I put on the search bar. If I put the search bar for wikipedia the URL bar uses that, if I put to amazon the URL bar use instead.

  As I said, he worked the way I loved yesterday and today it is no longer. I have not modified parameters between yesterday and today that this would lead to.

• If I reformat my iMac he will wipe away my iDevices when connecting to a new iTunes?

  Hello

  I want to reformat my iMac to a new configuration, because it didn't happen in 6 years. I wonder, once I reformatted the iMac how do reconnect you all iDevices without wiping those who, as I believe that if he has not connected before it gives you messages on the iDevice has not been linked previously you want to set up as new.

  This is the case, how can I get around this?

  It will not wipe your iOS devices. I saw this message: "not been linked previously you want to configure as a new.

  When you install a new iOS device and if she asks you after the failure of OS X, say Yes. I know that the message is not clear, but it will not wipe your device. Please take a look at this thread: question of itunes "implemented in the new ipad"in particular the post halfway down by ozZySPL that explains the problem. I did it myself without any problems.

• Only stopping a Mid-sync effect iPod music files?

  I just got a new iPod classic (160 GB). I have plugged in and was trying to synchronize the songs, when I tried to restore it for other reasons. He drew from the Mid-sync (rather than stop synchronization and clicking on eject), reconnected inside and I restored as I wanted to. I got things set up once again (this time I wanted to), and I restarted my music library synchronization. My question is this. In view of what I was doing, this will affect anything about the song, or files from my iTunes library on my iPod? Also, I reconnected my iPod all the time, and I did not detect any other 'chunks' of data/storage used by anything other than my music, apart from one very small slice called "other" as I have always seen with iPods, I plug (required information/data, I guess?)

  I think not, but I wanted to check a second time with people who know better.

  Thank you

  PS - It's actually a version repost/update of a thread/question I just posted a bit ago. I wasn't sure if people could always answer because I accidentally marked my question as a response. In truth, I wanted to know if at least a few other people had no answer to my question. Please understand I am actually new to using this forum... ^^;

  Once again, thanks a lot.

  Restore erases the iPod, so any corruption of data that you may have caused by disconnect (without ejecting first) would be gone.
