• Firefox spell check feature began to point out almost all of the words, regardless of if the words are correctly spelled.

  Firefox spell check feature began to point out almost all of the words, regardless of whether the words are spelled correctly.

  Tried to download and reinstall Firefox 3.6.8 but the same thing happens.

  Tried different web pages to see if it was a feature of a particular Web site, but it happened while I typed this entry in a field on a Mozilla Web site page.

  Such a shame, apart from the extensions topic spelling is one of my favorite features of Firefox!

  Can you tell what dictionaries were causing this issue?

  Only the selected dictionary has an effect.

  You can see which dictionary is selected if you right click in a text box and open the submenu language.
  
  Also make sure that [[X] "Check spelling" in the right click menu context has a tick.]
  
  Alternatively, you can try to move on the items 'Check spelling' and the new.

  There are a few rules of trade more that you need to consider.

  Do not forget that there are synonyms both PUBLIC and PRIVATE.

  Just because there is a synonym of a given name does NOT mean it's the only one who tries to create a given user. If a user tries to create a synonym private, you need see if the OWNER and the NAME, the two match.

  What is a user issuing a CREATE or REPLACE for their own private synonym? Is this OK or who need help also?

• query to bring 6 rolling pay check date at any point of time

  Hello
  
  We have a date dimension dim_date, who knows the date on the calendar. I need to write a query that will always bring 6 rolling pay check dates Ant any point of time. There are 14 days between each pay cheque date and it's fall Friday. Please take as reference below and help me to write the query according to my condition. Thanks in advance.
  
  
  Pay check date example:
  23/03/2012
  09/03/2012
  24/02/2012
  10/02/2012
  27/01/2012
  
  Thank you
  Jay.

  Hey, Jay,.

  If the dates are always exactly 14 days apart, it means there is always exactly 6 of them in a period of 84 days, so you can do something like

  WITH     got_target_date     AS
  (
       SELECT     TO_DATE ( '03/31/2012'     -- or whatever
                 , 'MM/DD/YYYY'
                 )     AS taget_date
       FROM     dual
  )
  SELECT     X.pay_check_date
  FROM     got_target_date     t
  JOIN     table_x          x  ON     x.pay_check_date  BETWEEN  target_date - 83
                                  AND        target_date
  ;
  

  If the dates are not always exactly 14 days apart, you can find the last 6 on or before the deadline in this way:

  WITH     got_r_num     AS
  (
       SELECT     pay_check_date
       ,     ROW_NUMBER () OVER (ORDER BY  pay_check_date  DESC)
                 AS r_num
       FROM     table_x
       WHERE     pay_check_date     <= TO_DATE ( '03/31/2012'     -- any target date
                              , 'MM/DD/YYYY'
                              )
  )
  SELECT       pay_check_date
  FROM       got_r_num
  WHERE       r_num      <= 6
  ;
  

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• try to check if a file already exists on the disk using fileExists

  All, Hy
  I'm trying to check if a file already exists on the disk in my action script.
  I found this link on fileExists:
  
  link
  
  So I tried somethink like this in my code, but to no avail...
  
  If (fl.fileExists ("queue: / / / C: / foo.txt"))
  {gotoAndPlay (2) ;}}
  on the other
  {gotoAndPlay (3) ;}}
  
  Is this not the right syntax?
  
  Thank you for your help.

  John,
  No I did not build the application of the swf with Mprojector. So I try with it.

  Looks like I'm not able to do that just use Flash Pro 8. I need to use a program like Mprojector to create an application and use its own functions.

  Thanks for your help.

• Sampling point frequent

  I have a 6008, accessible by DAQmx.

  I produce a custom feedback loop. As the analogue output has a sampling rate of 150 Hz, this is the maximum rate of the feedback loop.

  I'm trying to figure out how to make my analog readings.

  I have excluded finite samples (if I let up, I pass the same values and more; if I reset, it's far too slow)

  With continuous samples, if I take a unique data point, I'm not synchronized - I don't want to read the end of the buffer, I want the most recent.

  So I try sample N read, with-1 as the number of samples to be taken, that help said is the way to capture the whole buffer.

  I get an error-200279, who says I'm trying to read data that no longer exist because it crashed. But that seems like it should be a nonsense - I just say, give me what you got. Why bother crush if you are never just refuse to put her out in any more data and call a mistake, because you started to crush? It is frustrating especially since I really don't care for the newest item (or recent average for all purposes)

  There are a lot of topics around this error (-200279).

  Have a look here and try to understand exactly why you get this error. You too can share your code so that you can have a careful review and understand what causes the error, specifically in your code.

• Is there a way to check if a certain page exists

  I am writing an APEX application that dynamically generates pages based on some existing calculations. Most of the time it works well for me, but in some circumstances, I want to manually create a page and redirect it.

  Is there a way to APEX to check if a page with an ID or ALIAS exists?

• Hanging tool select disabled but time always snaps between sampling Points

  Hello

  In the Waveform Editor, when I Zoom in directly on the waveform, the points become visible. I have 3 Q: -.

  1. What are these points
  2. They can be changed
  3. How can I select (with the Selection tool) anywhere on the waveform?
     1. I deselected waspish and yet I am with zoom basically I can only place the time tool (TST) between the points visible, i.e. hearing snaps TST so I can not place exactly there where I want

  Thank you!

  The points show the individual samples in your digital recording.

  Jump to your last question, you cannot place the time between samples picker because samples are smaller individual representations of the original audio.  the lines between the samples are an artificial creation, making a waveform of samples.   There is an excellent video showing how digital audio works - I recommend highly a cup of coffee and a viewing: D/A and A/D | Digital Show and Tell (Monty Montgomery @ xiph.org) - YouTube

  Spacing of samples is determined by the sample selected speed which, in turn, is controlled by the clock system (Word clock).

  As for the editing... not really.  Older versions of hearing used to allow you to enter a sample and move it upwards or downwards, but the results could be unpredictable - under Nyquist theory there is only one waveform (i.e. one correct) which corresponds to the sequence of individual samples.   Changing a single sample (or even two or three) can force the system that analyzes samples and draws the analog waveform by doing a few calculations confusing, incorrect.   If you watch the video above and "read between the lines" you can see why that would be.

• [req] How to check if given oracle table exist or no + c#

  Hello
  All.

  code
  
  cmd.CommandText = "SELECT tNom tab where tNom ="OPC_GROUP "";
  
  cmd.CommandType = CommandType.Text;
  int length is cmd. ExecuteNonQuery());
  If (cmd. ExecuteNonQuery()) > 0)
  {

  }
  on the other
  MessageBox.Show ("Table does not exist");
  
  
  
  But this return code "TABLE DOESN'T EXIST" even if the table is already created
  
  What I m hurt?
  
  Help, please...
  
  Thnx in advance

  Try this...

  cmd.CommandText = "SELECT count (*) tab where tNom ="OPC_GROUP "";

• Single sampling Point Acq

  Hello, a little info on my system and I to start. I'm under LabVIEW 8.6 and using the NI USB-6259 box as my DAQ hardware. I'm new in the world of only having been LabVIEW use this configuration for 3 weeks (but a nice step to the top of the Win95 system I was using).

  I'm trying to order and circuit operating at 8 kHz. I want to read in a voltage of the circuit, detect a break in its derivative and then send the output voltage back into the circuit based on its signs at these crossings. To safely control circuit, I need to taste well above 8 kHz.

  The issue I'm having is speed limits due to a loop based around a DAQ Assistant of "1 sample (on request). I read a lot of messages saying to use timed HW sampling but I do not think that my DAQ hardware supports it. I used clocks to get a rough idea that my loop runs roughly 25 Hz.

  I don't know if the problem is in inefficient coding or limitations of my hardware and software. Attached, you will see my current VI.

  You're right, you use the acquisition of timmed softwared, you want to run in continuous mode, The 6259 should be able to acquire up to 1.25 MECH. / s.  Try to put it in place with the daq assistant since you're new to labview, or look at examples of analog acquisition.  essentially, you want to read in a loop using buffered continious CQI, then send the results to your vi loop or slave to the processor.   I would like samples at 5 - 10 times the 8 kHz to get a good representation of the signal you.  faster that the x 10 will give you nothing but too much data to deal with.  8 kHz is not too much data and you might be able to treat it in the same line as your read daq.
