• Problem with multiple downloads with the router. Allows you to change the TCP MSS value?

  Original title: TCP MSS

  Hi all.

  I currently have a problem with multiple downloads with my current router.  If I have two current downloads at the same time I have no access to all web sites.  It's almost as if the downloads take my meaning of bandwidth there is more nothing for ordinary surfing.

  As a test I put an older router on my system and have a significant improvement in performance.  I have 2 downloads in progress and also surf at the same time.

  To compare two routers, I noticed that the only real difference between the two is that the TCP MSS value is set to '0' on the router of the problem, and then assign him 1392 (MTU - 40) on the router to elderly who gives better performance.

  It is my understanding that this value governs the size of transmitted packets.

  My question is this:

  What is the MSS value which is causing the problem?

  Congratulations in advance.

  Be sure to interpret the values. The '0' means no not literally because the link would not work. It is likely, that it allows the local device set limits for the link. Don't forget that there is a Maximum value and as such can be any value up to such limit as defined by all devices in the path.

  You can try capping manually but it is unlikely that any local limit will come to effect unless you set very low.

• SQL Toolkit crashing with multiple threads

  Hello everyone and happy new year!

  I was hoping someone might be able to shed some light on this problem. I update an older application to use multiple threads. In fact, the thread that is causing a problem now is created by using an asynchronous timer.

  I use CVI 2010, and I think the SQL Toolbox is version 2.2.

  If I execute a SQL statement from the main thread, there is no problem.

  stat = DBInit (DB_INIT_MULTITHREADED);
  
  hdbc = DBConnect( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=sample.mdb;Mode=ReadWrite|Share Deny None" );
  hstmt = DBActivateSQL( hdbc, "SELECT * FROM SAMPLES" );
  
  DBDeactivateSQL(hstmt);
  DBDisconnect(hdbc);
  

  If I add code to perform the same duties in a reminder of the timer, it causes a stack overflow error.

  .. Start the main thread

  stat = DBInit (DB_INIT_MULTITHREADED);
  
  NewAsyncTimer (5.0, -1, 1, &gfn_quicktest, 0);
  

  .. end of main thread

  .. and then the reminder of the timer

  int CVICALLBACK gfn_quicktest (int reserved, int timerId, int event,  void *callbackData, int eventData1, int eventData2)
  {
    {
      int hdbc = DBConnect( "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=params\\sample.mdb;Mode=ReadWrite|Share Deny None" );
      int hstmt = DBActivateSQL( hdbc, "SELECT * FROM SAMPLES" );
  
     DBDeactivateSQL(hstmt);
      DBDisconnect(hdbc);
    }
  
    return 0;
  }
  

  The program crashes with a stack overflow error when the DBActivateSQL statement is called.

  I understand that the Access ODBC driver can not support multithreaded, but I only connect to this base starting from the same thread with these 2 statements only so it should be good?

  Any idea would be appreciated,
  Thank you
  Ed.

  I just tried this using the sample provided with CVI access database. It uses a DSN instead of mdb. It has worked out well. I see that no reason multithreading would be a problem here, if you open and close the connection in the same segment of code. I see that you use params in the asynchronous callback connection string. Where did this come from? Maybe try to use the database and see if it works.

• Problems with multiple worksheets XY plotting (program generates repeated data)

  Hello

  I want to make a small program that will reduce the amount of time to go forward with the measurement data. I get data into .dat format, where all the files consist of frequency measurement with an X and a Y column. The problem is that I made 4 experiments (X column is the same for each experience) with 15 measures file each and more than 500 points of measurement in each file. I would like to make a simple manipulation and this copy that information to a file with same X column and multi-column, later I could use these data with Excel or origin (do it manually, it's frustrating and time consuming).

  At the beginning my program reads the background information with X and Y (b), and after I open the worksheet to insert the X and data of Y (n). (make a simple manipulation, like dividing Y (n) /Y (b), program show a graph of the current data and another graph multiple data, which are stored and must be exported in .txt, .dat or directly to Excel (which is more preferable)). I'm OK with the opening of several files of data, but which are not okay with copy/paste file and handle all that data manually, but that's my motivation for this program.

  The attached example can do all this (except for the entry in the file). He draws multiple charts on a XY chart using cluster and travel records. It is even possible to extract data in Excel, all that graphic, but the real problems comes with data are always added because of the loop. This gives a lot of empty and repeated data later. I'm jonesing to get rid of this. I have also attached several files of measure: 1 background and 3 measures.

  P.S. I tried to save time thanks to this program, but now, I spent more time than if I did it manually

  Your program absolutely no sense. What is the purpose of the structure of sequence? It just sits there, operating both in parallel to the while loop. Probably that you read from the local variables before other parts of the program had a chance to write valid data for them.

  In the while loop, you have a case of timeout that adds the same data over and over again, every 50ms. Why?

  Your mechanical actions "switch release" are misguided. Use actions to latch and remove structures deal as part of the event.

  Try to rethink the problem once the mode, and then solve the problem with 20% of your current code. See how far you get.

• Major problems with multiple items of page on the web viewer since the last update

  In the last days, we had problems with all our multiple page items that are newly updated or added on the web viewer.

  Scrolling of pages just to repeat content again and again and true articles page see first pages content overlaid on all subsequent pages. It seems that something important broke in the way that the dps push articles to the webviewer, as is happening through fact sheets and articles. This means that we cannot publish anything until it's resolved.

  Someone knows something similar? Any suggestions?

• Problems with multiple framerates and Blackmagic Decklink 4 K Extreme reading

  Recently, I exchanged by AJA Kona card for extreme Blackmagic Decklink 4 K in order to get external followed in DaVinci Resolve.

  I work in a 1080 p 23.976 project that includes a 29.97 SD and HD images. Loading these images of 29.97 FPS in my layer source footage, I meet regularly with frozen reading (the triangle of game in my toolbar becomes a symbol of the square and stays that way). From there on, I am unable to playback images in any scenario and requires a complete closure of the system to return to normal! The problem is apparently BOUNCING, with successful reading happening sometimes.

  Images of 29.97 was DVCPRO, I tried to transcode to Prores to solve problems. No dice. I think it's a problem related to the inability of the Decklink to manage several rate display on the fly, but wanted to present here, too. I also experienced delays intermittent sync on my monitor.

  DeckLink driver 10.0

  First CC 7.2.1

  Mac OSX 10.9.2 (mavericks before the same problem)

  Hi Andy,.

  You should not have problems with Blackmagic manage several formats on the fly. However, I believe that the problems of reading frozen that your description is related to the Desktop Driver video 10. I suggest rolling back to 9.3.3 for now. Blackmagic now turns on this issue.

• problem with multiple digital signatures by deactivating the fast web view

  Hello, I use acrobat pro 9.1 and have questions regarding a problem with several signatures on a pdf document.

  Why I ask the question below? My job is to prepare PDFs for submission to the FDA. The FDA requires, among other things, the documents submitted electronically have quick view active web.

  I am currently exploring ways to use digital signatures to sign pdf reports and always make sure they are spec FDA compliant. My question concerns a document which would have several signature fields. What I do, it is to create at least two signature fields in the doc and then save and optimize everything for fast web viewing. When I connect the first box and save, the file retains the fast web view state. Yet, when I apply and signatures past one, the file is then left for quick web display with no obvious way to turn it back on. I'm confused as to why it gets disabled after the second, and not just after even the first condition has been signed. And, of course, I would like to know if it is possible to maintain the fast web view and how to do it. I will gladly accept "tinker under the hood' suggestions file if they exist as well.

  Please let me know if something is not clear or you would like more information.

  Thanks for your time and your help.

  Hi Vlad,

  Real Michael has got the right answer. A "Linearized" file (which is a file that has been optimized for fast Web view) aims to get the first page to display as soon as possible so that you can start playing without waiting for the rest of the file to download. Incidentally, the first designated page should not necessarily be page 0 (use of PDF has zero according to the pages counting system), but it usually is. The PDF specification, "the main objective of linearized PDF is optimized PDF documents viewing read-only. It is expected that the linearized PDF generated once and read many times. Incremental update is still permitted, but the PDF is is more linear and subsequently is treated as ordinary PDF. »

  When you open a PDF file the first time that the backup process is a full 'save', it is the whole document is rewritten, so there is no more than two percent markers EOF (end-of-file) inside. The first expressions of folklore means what page to see the first and the second EOF designates the end of the rest of the file (so the browser knows when to stop downloading). However, when you add a second signature (or even longer) the file is saved as a "record growth" and new data is appended to the original file. It is that you can do a restore to the previous signed version and allows Acrobat/Reader verify the integrity of each signature regardless of any other signatures. It's the incremental save, breaking the linear optimization of the file.

• Problems with multiple locations

  I am having trouble wiring a table 2D plotting a graph of waveform information. According to everything I read in the documentation, this shouldn't be a problem, but it is. One thing I read said to activate the option 'Convert table' draw with a 2D array, but this option is grayed out in the menu. The strange thing is that there are other waveform graphs in the project who accept 2D data tables but I am unable to find a difference in the options between them. I have attached a few photos to see what I mean.

  Thanks for your help!

  I discovered the problem - the graph was not initially wired to a 2D array. I guess it maintains its initial entry 'type' for the duration of the program.

  Thanks for your time though.

• WTVConverter problem with multiple audio streams...

  The WTVConverter MSFT includes Windows 7 does not correctly handle multiple audio streams. The WTVConverter in the conversion of the format ".wtv' to '.dvrms' instead of keep the main audio stream retains the other stream audio visually impaired. Usually, he keeps the other stream audio visually impaired. NCIS and NCIS Los Angeles, CBS programs have this problem because they include signals SAP (accessibility for blind and partially sighted options)

  How can I tell WTVConverter to include only the main audio instead of the stream audio visually impaired

  Thank you

  Hello, Chandra

  If you think that there should be an option to select a stream when converting, you can leave your comments on the following link:http://mymfe.microsoft.com/Windows%207/Feedback.aspx?formID=195

  In addition, you can try searching for a free replacement program convert WTV files.

• Problem with Multiple Choice Quiz

  I tried several times to insert a multiple choice quiz success in my slides. The problem is that when I try to take the quiz (for a preview), I have to click several times and wait several boxes pop up coming (correct, click anywhere; incorrect, etc.). All these boxes pop up show before he let me go to the next slide. Anyone know what I need to change?

  Are you found using the preview feature in presenter or switch to slide show view (F5) in PPT? Looks like you're watching just PPT presentation, who must play through all the animations on the slide.

  You see the same questions if you publish the presentation on site and view the published version?

• Problem with multiple display devices

  Hello

  I've recently upgraded to Adobe CC and I am trying to configure Edge inspect on my iPad and iPhone.

  I added two devices defined in the instructions, but when I try and get an overview of these two devices, I get the following message:

  Use of multiple devices is a feature of the version complete edge inspect. Upgrade now to connect several devices simultaneously.

  Does this mean I have to buy another upgrade to allow multiple devices to be viewed?

  Any help appreciated.

  see you soon,

  Blue-insurance

  Inspect edge has two pricing options, a free version, which only allows one device to connect to both, and a full version that allows an unlimited number of devices to be connected simultaneously. If you are already subscribed to the full version of edge inspect try to connect log out of the application of edge inspect and then again to solve the problem.

• Problem with multiple series - CFCHART

  Using CF9, trying to create a simple table with two rows.  Problem is that when there is no value, CFCHART draws a line, but with values of '0 '.

  The first series is a set of values monthly (12) one for each month in 2011. The second series is also the monthly values, but for 2012, CDA (January to may 2012).  For all values between 90 and 100, so I have it set to "Scale" in order to see if the year is better or worse.

  I'm trying to draw series 1 (2011) on a single line and 2 of the series on a second line.  This allows to compare the results of the year on the other.  Have two QofQ, one that contains the twelve 2011 values and one that contains the five 2012 monthly values.  The x axis values are numbers (1-12 for 2011 and 1-5 for 2012).  However, I have re - format the results by using 'CreateDate', so CFCHART can identify a date and format / view only "months" on the graph (e.g., JAN, Feb, Mar... (DEC).   This works, because the bottom of the graph shows JAN to DEC.

  The chart shows 2011 correctly with 12 points and a line.  But for 2012, it shows points 5 (January-May) with their values and then shows Jun - Dec 2012 with values of ZERO.  So, on the plot of may 2012, you have this great line that goes from 90% in May to 0% in June, then 0% for the rest of 2012.  I want only to draw the line in may 2012.

  If you delete the series 2011 of the CFCHART, it appears correctly and displays only 5 months in 2012 (January-May).   And if you delete the 2012 series, it appears correctly, with all 12 months in 2011.

  
  I just need it to appear exactly like that, when two CFCHARTSERIES are used.   Even if you < CFOUTPUT > the application of 2012, you get 5 points, Jan - may.  So don't know why she wants the graphic elements 12 in 2012 with all zeros for June - dec 2012.

  Appreciate any help/tips on how to get year lines, with 12 data points for 2011 and 2012 5.

  You must disable interpolation. However, there is also a bug in some versions.
