• Misunderstanding NIDAQmx Timebase revisited

  I use a USB-6251 box with analog sampling controlled by an encoder.  In some cases, the user wants to divide the encoder to achieve a lower sampling rate.  I used code similar to that described in the previous posts on the "misunderstanding NIDAQmx Timebase'.  This solution worked for relatively low sampling frequencies but fails when the sampling frequency is greater than about 120000.

  In this code, if the divisor is 1, the code works to achieve a sampling rate that I can reach, about 500000.  If the divisor is two, and the sampling frequency is less than 120000 when the code is run, it works until the encoeder speed is increased so that the sampling rate is higher than 120000 where sampling simply stops.

  If the speed of the encoder is more than 120000 when code is started, the real divider seems to be increased until the sampling frequency is less than 120000.  No error is returned for each of the function calls.

  I tried several variations of this code and many variations of the value of daq_card.max_scan_rate (s) with no difference in performance.  normally, the value of daq_card.max_scan_rate is 1250000 for box USB-6251.  I tried several different values in the two localities where the value appears in the DAQmxCfgSampClkTiming() function.

  The data is read from the box USB-6251 to a PC 12 times per second.  I tried setting the buffer size just above the minimum for the sampling rate and read times and also well beyond this size without a change in performance.

  My code (edited to remove the error checking):

  sprintf (chanString, "/");
  strcat (chanString, devName);
  strcat (chanString, "/ PFI0");

  If (daqencdiv == 1) / / no division (Division 1)
  {
  connect the sample clock directly to PFI0
  status = DAQmxCfgSampClkTiming (acqTask1, chanString, daq_card.max_scan_rate, DAQmx_Val_Rising, DAQmx_Val_ContSamps, daq_card.max_scan_rate);
                  
  }
  else / / if the encoder must be divided
  {
  Discussion Forum suggestion 18/03/08
  Choose "embedded clock.
  status is DAQmxCfgSampClkTiming (acqTask1, NULL, daq_card.max_scan_rate, DAQmx_Val_Rising, DAQmx_Val_ContSamps, daq_card.max_scan_rate);.

  Select PFI0 as the source of 'the embedded clock.
  status = DAQmxSetSampClkTimebaseSrc (acqTask1, chanString);
  On-board clock divisor value daqencdiv
  Note that this will not work for daqencdiv = 1.
  status = DAQmxSetSampClkTimebaseDiv (acqTask1, daqencdiv);

  }
  Start the task of acquiring
  status = DAQmxStartTask (acqTask1);

  Finally solved this with a lot of help from Sara Lewandroski, (Applications Engineer NOR)!

  The problem occurs because the DAQmxCfgSampClkTiming() function is not always set the clock to convert properly, probably because he does not know the maximum frequency of the external sample clock.

  The solution is to explicitly set the clock converted at a rate that allows to convert the desired number of channels before the next sample happens clock.

  The function to set the clock to convert is:

  DAQmxSetAIConvTimebaseDiv (acqTask1, 20);

  where 20 is 20 MHz clock divider.  With this divider set to 20, the convert clock frequency is 1.0 MHz which is the maximum for the USB-6251 case multichannel.  With two channels, this allows the sample clock to rise to 500 kHz, until the data is lost.

  This function is not a function panel and not every upward in the list of functions within the CVI DAQmx.  The only documentation that I could find is the reference C DAQmx help.  Even there it does not appear in the content, but can be found using the search function.

• Data query Essbase with MDX of misunderstanding

  Can anyone help with a basic misunderstanding of the mine during the selection of the data of Sample.basic with MDX.
  
  The Essbase Adminstrators guide says:
  
  "The intersection of a member in a dimension and a member of each of the other.
  Dimensions represents a data value. »
  
  The following example from the same guide still managed to return what appears to be an empty value of sense without any context.
  
  Select
  {Jan}
  on columns
  of sample.basic
  
  Jan
  8024
  
  Surely any number and significance only makes sense when they are associated with a member from each of the other dimensions?
  
  And
  
  Why Essbase chose this value for Jan rather than any other that I see in the source Calcdat.txt file?
  
  Thank you

• Adobe to misunderstand editing tools

  I can't know the difference of what is proposed between Cloud of Document PDF and Adobe Acrobat. I need an easy tool for my business @ special www.JessiRitaHoffman.com--en, a tool for editing of the manuscripts of the customer. (I'm a book publisher). I want to see how Adobe compares with the tools available in Word but I'm not clear what application has the function of change that I would need. I am told that Adobe editing tools are more difficult to use than the "track changes" feature of Word. Someone at - it experience with this?

• Have misunderstanding with addEventListener

  Hello!

  I have an asset that is a normal MovieClip and I want to add an event listener.

  Event handler, however, will be a method of a generic class that is not extended to any of the AS3 classes.

  So I have a code like this:

  class Foo {}

  public void Foo(asset:MovieClip) {}

  asset.addEventListener (MouseEvent.CLICK, this.handle_click, false, 0, true); the use of weak references

  }

  private void handle_click(e:MouseEvent) {}

  trace ("Click!");

  }

  }

  It compiles well but the listener does not at all. Once I change the Foo class be extended form or Sprite, the listener magically begin to operate.

  Also, when I do not use the weak reference, it also starts to work.

  I don't understand why. The problem could be that active object gets garbage-collected so the event listener is destroyed, but this isn't the case, the asset continues to exist on the screen.

  OK I got it. The asset was not garbage collected, but the instance of class Foo has been, higher, while it was hard to notice several levels.

  To prevent garbage collection only keeping not references external for all instances, you can just make a reference within an instance itself, similar to this:

  (not saying it's better or anything useful at all, just a casual employee to find who might have some implementatons)

  class Foo() {}

  class GC protected before you call unlock()

  private var: locking function.

  public void Foo() {}

  This.Lock = this.unlock;

  }

  private function unlock() {}

  This.Lock = null;

  }

  }

• Misunderstanding of recursive subquery

  Hello
  
  To summarize our boredom, I have set up a test folder. Our data source are:
  

   
  GRP  ITEM
  ------------------
  A       F
  E       F
  C       G
  E       G

  We want to join on column ELEMENT to generate recursively
  
  An E (get by A-> F-> E F)
  C E (get by C-> G-> G E)
  A C (get by A-> C-> E E)
  
  
  So, we write the following query:
  

  with
    datas
  as (
  select 'A' as grp, 'F' as item from dual union all
  select 'E' as grp, 'F' as item from dual union all
  select 'C' as grp, 'G' as item from dual union all

  )
  select * from RR
  order by lvl

  but the C line is not generated :-(
  
  
  Can someone explain why recursion do not pass on the 1 iteration?

• Misunderstand CSS Layout and padding

  Hello

  I'm having serious problems of understanding the CSS layout techniques and the impact of padding and hoped I could get help.

  Here are some pages that show examples of what I do "get". The first offer padding causing the layout to look right. The second has no filling but don't have as I expect. In addition, the amount of text affects the div "down" as well. I'm an old hand at HTML and could make this layout in my sleep by using tables. CSS is different and frustrating.

• Airport Express does not extend WiFi range

  OK, I posted a long time will cost about an airport older Gen Express not extending my wifi range when implemented to extend (wireless) and connected to a network of Apple (Airport Extreme). No solution, so I gave up.

  Still frustrated by the lack of a strong wifi signal to my back door / Garden (it is a small house!), I bought a new Express and set it up again to extend my current network, placed it on my window sill back room (where I get a pretty good wifi signal on my iPhone and iPad), but about 6 feet of him, the other side of the glass in my garden I get a flicker of 1-2 bars the signal strength that is de-energized intermittently.

  I get no significant (or even vaguely reasonable) increase in force wifi when I approach from the Express, but increase next to the extreme.

  Or should I put either the express until properly (I'm sure I'm) or I am fundamentally misunderstand the term "extend a wireless network. Alternatively, I bought 3 years 2 defective Express apart.

  Can anyone help?

  See you soon.

  You have a handy Mac laptop? If so, we can run tests to understand the current quality of the signal at each location where you want to have a Wi - Fi access. If all goes well, we can find better place to place your Express extension for your goals of networking.

  Your statement makes no sense to me or I am misunderstanding you. Of course, the photos are stored in the camera when taking pictures with the camera. Where you wait to store photos?

  IF you mean that you see the pictures in the thumbnail view while using the camera application, they are not duplicated in any. You just see them in the camera application, but they are stored in the photos app.

  Who need this lyrical sh * t? All my friends is also frustrated by this function, because if you need a specific date for the quote or shipping screen, you will need to do a lot of unnecessary travel.

  I mean - if you want to find something and need to translate "what the date was Saturday?", you need to go to calendar and look here, what date was Saturday.

• Clipboard in Fx Android does not work why?

  (Hope this isn't a duplicate: when I started posting, the system asked me to confirm my e-mail address and said that my message would be displayed, but the system said now I haven't sent anything.) A little later: my mistake, a misunderstanding of the language of the system forum. I had posted, which seems to not be the same as sent. My original post was, in fact, posted, but I looked in the wrong place.)

  With Android Kitkat 4.x, I could set up an account with Keepass, get my user name or password saved to the Clipboard, then go to Fx, set up a logon account page, press and hold in the area id or password, and the popup 'Paste' seems to me; clicking on the icon would transfer the data from the Clipboard to the corresponding logon box.

  With Android 5.0 Lollipop, it does not work: instead of the paste popup, I get an arrow in the login box telling me where to type in the data. I know the Clipboard Android works: using Keepass, I can record the date in the Clipboard and then, for example, go to Gmail, hold on, 'Paste', click on that and see the Clipboard data transferred to Gmail. The Fx problem exists since I received my phone Moto X last March thanks to every Android Fx update, the most recent of which this release.

  When I long press on the field, I get a bar upstairs that has an icon of the dough. I have attached a screenshot (reduced size) of what I see. (It was one thing to chance, that I copied, because I don't have Keepass.)

  You don't get something like this?

  Oops, perhaps it is 5.1 and not 5.0
