• Select the first 20 days of the month for a given date

  Hi gurus,
  
  Please let me know to select the first 20 dates for a date supplied by using a parameter.
  
  For ex -.
  
  Suppose I provided a date by using a parameter - January 13, 2012
  
  The query should return me - 01-Jan-2012, January 2, 2012... January 20, 2012
  
  or if I get home on 23 March 2012
  
  The query should return me - 01-Mar-2012, March 2, 2012... 20 March 2012
  
  Thanks in advance.

  Hello

  Here's one way:

  VARIABLE  target_date     VARCHAR2 (11)
  EXEC     :target_date := '13-Jan-2012';
  
  SELECT      TO_DATE ( SUBSTR (:target_date, 4)
              , 'Mon-YYYY'
             ) + LEVEL - 1     AS a_date
  FROM     dual
  CONNECT BY     LEVEL     <= 20
  ;
  

  Note that this does not take account the part of: target_date that represents the day of the month. When you use TO_DATE without giving a date of the month, it defaults to the 1st of the month.

• Analyze the failure because that returned data have XML as code

  I have a HTTPService that makes a call to a PHP file to collect some data from a database of vulnerabilities. It works 99.9% of the time. However, there are some cases when I get the following text:

  I have debugging in my PHP files and I know with certainty that data are being grouped into XML format suitable for a response back. And when compared to every other answer that works, it's exactly the same (XML sections / tags).

  Order deny, allow
  refuse to all the

  Could it be causing my problem? It is not part of my XML, but rather the data returned by the database about a particular vulnerability in Apache.
  
  Anyone have any ideas on how to deal with this?

• Date and time on the graph (read from Excel)

  Hi everone, I m new to this forum.
  I'm stuck with one of my projects.
  The program is, READ the excel file and it draw on the graph.
  Registered solar energy output is doing, basically I'm trying to see the chart of the outputs and readings at different times.
  I have problem to read time colum, I want to show in the time indicated on the excel on the chart.
  and like 4-5 minutes, to determine the curve because it has 9000 + points.  any suggestion to reduce points?
  I'm new to labview.

  Here's a very quick project on what you could do.

  Of course, you could also extract the headers and place them in the rings for a natural selection more. Only parties with controls belongs in a loop if users should be able to select the columns dynamically. You must also analyze the column time differently. Modify if needed.

• How to analyze the data of 10 bytes encoded in the HH306 of Omegatte data logger/thermometer?

  I am trying to write a simple code for a HH306 of OMEGAETTE thermometer/travailleursduweb.com data recorder.

  That is the problem. I communicate with the device via RS - 232, using Labview 8.5.1 and windows xp. I ask her for "all the coded data", which is actually the only option. He returns 10 bytes of encoded data, the manual describes the meaning of each byte and I understand that. The problem is that I can't analyze the information for use in labview, for example: I want to extract the temperature and simply display it.

  on request, I get: 10bytes (read as a string from the serial port read buffer): display HEX: 02 00 A8 48 FF EF B6 49 B6 03 is perfect, and what I expect.     Display codes: \02\00\A8\B6H\FF\EF\B6I\03 The Normal display is a series of special characters, I don't understand, especially since I don't think they are ascii characters that must match returned hexadecimal numbers!   For the life of me, I can't understand how to extract the information (what are the 48 6 hexadecimal display) of what is returned. All string manipulation functions seem to work only on what is given in Normal view. (The 4th and 5th byte of the data are the codes of the BCD for temperature: for example the temperature was 64.8 degrees farenheight when I took this reading).

  Can someone help me to analyze the data returned by this device?

  Ok... I think that I thought about it. I found this: http://digital.ni.com/public.nsf/websearch/77C8F61D36F5A23086256634005ACB38?OpenDocument.

  I guess the normal display garbled is corresponding to each hexadecimal ascii characters. I'm just not used to seeing characters beyond the decimal number 127 ascii or hex 7F.

  So, basically, to analyze the 10 bytes of data:

  (1) break the string read from the serial port in the 10 ascii characters (using String subset vi)

  (2) son of each output string in the left input of 10 separate Type vi Cast.

  (3) wire a constant U8 in each terminal 'type' VI Type Cast.

  cables of 4) the chain of each Cast of Type vi output to the input of a number hexadecimal string vi.

  (5) concatenate or use as you wish as hexadecimal numbers (now in string format) which cause.

  See you soon.

• How to analyze the data of the cDAQ and Signal Express, especially after analysis?

  In the first series of tests of my instrument, it took longer than expected for the race.  Thus, the data was saved in 6 days.  The file is too large for export to Excel.  At the beginning of the project, I was as ignorant as I could go ahead and add analysis and the scaling of measures.  By the scaling, I mean my data of switching current dew points or whatever it is that I record.

  How to evolve the data to read the output data as expected 4mA = point of dew of-20 C or 0 PSIG?  Can I pre program this to be recognized for each event?

  For real analysis I am doing – I would first analyze the data I recorded and choose different points to send to Excel to graph and analyze.  Is this possible?

  Secondly, I would like to know how to scale and analyze my data in the project without having to do this later analysis in the future?

  I have a cDAQ-9172 with LabVIEW signal Express 3.0 that uses four modules - 9211 2 modules of thermocouple, my 4-20 1-9201 module +/-10V module and 1-9203.

  Thank you for any assistance.

  Hi Patricia,

  "' You can do this by adding a step Load/Save signals ' analog '.  I hope this helps!

• dispplaying data on the graph of waveform inside/outside while loop

  I create a vi using the random number generator, entering the number in the function(express>>arithmateic>>maths>>trig>>sine) fishing and connect the output of the function sine waveforms. Table of waveform show no problem. If I replace the with graphic waveform table, I get an error that the source type is differenct type of sink. I then put waveform chart outside loop everything hoping that tunnel would act as a table, but still I get the same error. I then put build table palette between all border and loop waveform graph which is placed outside the while loop. I get no error, but no data is displayed on the graph of a waveform. Theoretically, if I press stop I would see a distorted sine wave on the waveform graph, but this doesn't seem to be the case. I am wondering how to view data on the graph of a waveform in such cases!

  Thank you in advance for reading and help!

  See you soon

  First of all, you can take a part of the basis of LabVIEW tutorials.

  Since you need to work with a chart and it is the preferred method to display data point by point, I don't know why you try to use a chart. In any case, you cannot use all simply a table of generation because that would be just the result of the last iteration and your graph indicates it is a single point. If you activate autoindexing, then you get all the values, but not before the end of the loop. If you were to use a shift register and the build dashboard, you might place the graphic inside the loop, but then you would face performance issues that the table would grow uncontrollably.

• Analyze the flat file data in a nested structure.

  This has been driving me crazy all day long.

  I have a flat data file I want to analyze in a nested data structure.

  Small sample data:

  0 HEAD
  1 SOUR FTW
  2 VERS Family Tree Maker (16.0.350)
  2 NAME Family Tree Maker for Windows
  2 CORP MyFamily.com, Inc.
  3 ADDR 360 W 4800 N
  4 CONT Provo, UT 84604
  3 PHON (801) 705-7000
  0 TRLR
  

  If anyone recognizes this, yes it's a small piece of a GEDCOM file.  That's what I'm trying to analyze.  For someone who is not familiar with this data format.  The first number is the level of a data element.  Level 0 are elements of the root of a data segment.  Level 1 lines relate to the data of level 0 line previous closest.  Level 2 lines relate to the level 1 data line that precedes the closest. And so on.

  Here is an example of the desired output, the different elements to the related parent of nesting.

  <cfset foobar = {
   HEAD = {lvl=0,
   SOUR = {lvl=1,data="FTW",
   VERS = {lvl=2,data="Family Tree Maker (16.0.350)"},

   CONT = {lvl=4,data="Provo, UT 84604"}},
   PHON = {lvl=3,data="(801) 705-7000"}}}},
   TRLR = {lvl=0}

  I think I'm looking at a kind of recursive function to embed these data correctly, but I just can't figure out how to do.

  I have this basic function that will display each line of data in a separate structure key

  <cffunction name="parseFile">
       <cfargument name="file" required="yes">
       <cfargument name="line" required="no" type="string" default="">

            var subStruct = structNew();
            var cur_line = "";
            var next_line = "";
            var line_lvl = "";
            var line_key = "";
            var loop = true;
            
            if (len(trim(arguments.line)) EQ 0) {
                 cur_line = fileReadLine(arguments.file);
            }
            else
            {
                 cur_line = arguments.line;
            }
            
            do {
                 if (not FileISEOF(arguments.file)) {
                      next_line = fileReadLine(arguments.file);
                 }
                 else
                 {
                      next_line = "-1";
                      loop = false;
                 }
                 
                 line_lvl = listFirst(cur_line, ' ');

                 returnStruct[line_key]["level"] = line_lvl;
  
                 cur_line = next_line;

  <cfdump var="#gedcom_data#" label="Final Output">
  

  I tried many ways to recursively call this function in order to nest the elements.  None of them have produced await in the above example of hand coded output.  Which made me the closest is recursive call, the function parseFile() towards the end of the while loop if the following line is greater than the current level of line:

  if (listFirst(next_line,' ') GT line_lvl) {
       parseFile(arguments.file,next_line);
  }
  

  
  It works pretty well, as long as the next level of line is the same as or higher than its previous level of the line.  But once the next line level is lower, the recursive call will not return to the appropriate parent level.  The current function call ends just on a loop on the data file.  Everything that I tried to provide a correct output for recursive function calls when the next data line belongs to a line parent just a horribly distorted data.

  Yes, that's exactly it. I think that the node must always be added to the stack.

  I just had a period gave me. But that's what I thought.

  That is to say...

  While (not FileISEOF (gedcom_file)) {}

  line = fileReadLine (gedcom_file);

  extract data from the node

  node = {};

  node.LVL = listFirst (line, "");

  line = listRest (line, "");

  key = listFirst (line, "");

  If (listLen (line, "") gt 1) {}

  node. Data = listRest (line, "");

  }

  Download the most recent ancestor of the battery

  lastNode = stack [1];

  If it is a brother/ancestor, look for its parent

  While (arrayLen (stack) & node.lvl lte lastNode.lvl) {}

  arrayDeleteAt (battery, 1);

  lastNode = stack [1];

  }

  Add to the stack

  arrayPrepend (stack, node);

  Add this node from its parent

  lastNode [key] = node;

  }

• The graph refresh is very slow with large data sets

  When the graphics of large sets of data in tiara, the construction of the graph is slow (3 pts M takes 30 sec). Fair enough-, the problem is, however, some little change do you later to the curve, it will refresh all over again, and during this time you can't do anything else with DIAdem.

  Any way to relieve it?

  Problem seems to be solved - restart of DIAdem restored time to update to an acceptable level, or at least it seems that restarting is the only change.

  I tried later with the two parameters of charge mentioned by AndreasK and both just as powerful.

  I tried remote desktop access and it works all too well - also go remote DIAdem (to see if it's a graphics driver issue)

  I feel kind of silly not being able to identify what was wrong and I thank you for your help.

• How the graph data are resampled pixels?

  A test, I created two identical graphs with land areas 500 pixels wide and a noisy sinusoidal signal of 1000 samples.  A chart displays the waveform right, while the other got the results of the use of the function Arrray to decimate to halve the number of samples.  They are not the same.

  Up to a waveform graph does exactly when it displays a data value larger than its width in pixels?

  

  As you have noticed, the graph is a little more intelligent that you expected.  When the number of points exceeds the number of pixels, a form any resampling must take place.  A simple decimation as you tried would eventually pass some interesting points.  Instead, the outliers receive priority when selecting which points to display.  Strong in this way, peaks and dips appear even on a large scale.  Reproduce this behavior yourself can be tricky.  And once you reduce the data set, the points are gone and zoom is not as effective.

  Usually, I try to let the chart to do as much as possible.  A simple and effective way to reduce the size of the data you have to ship on the network is to use the SGL precision instead of double precision.

• data is plotted on the graph of absolute time delay

  Hi all

  I'm plot data on a graph of absolute time and I find 2 hours difference between the data displayed by the debugger (left) and data on the graph (X - SCALE AUTO).

  The time saved in ptTime, was acquired by using the function 'time' and the PC has Amsterdam, Berlin, Rome as time zone.

  Here, under a screen shot that implemented the code, the debugger and the result.

  The debugger is also showing the version in good time!

  Can anyone suggest me how to process data in order to have the same result on the debugger window and on the graph?

  A big thank you and best regards

  Question: in the CVI debugger show you, the time_t variable appears as a double, while its definition in 'time.h' is ' typedef unsigned int time_t; "so I am a little confused.

  Response: I did something nonsense in this screenshot: I took a variable of type double (it happened to be a UIDateTime, actually) and configured the debugger to format as if it were a time_t variable. The formatted values that the debugger shows me, therefore, are not valid, of course. But I just wanted to show the time_t format, because it corresponds to what you have in your screenshot, and I was already suspicious that you use time_t variable to pass to the curve.

  Furthermore, if you are not familiar with the way in which you can change the formatting in the debugger, this is how you do it:

  

  Usually, the debugger can automatically pick the best format to use, based on the data type of the variable (for example, with variables of time_t). But in this case, what the debugger calls a variable "Date Time" is all just a double. The debugger cannot assume that you want to display all your double variables as a 'Date Time', and so you need to replace yourself.

  Question: I was not able to find UIDateTime using the ICB type, this is the value returned by GetCurrentDateTime(double *)?

  Response: There is really no such thing as a type of data "UIDateTime". I've been a bit remiss with my terminology. Unfortunately, when you're dealing with dates and hours, there are several possible representations of these quantities in the world of C, and it is important that you use the correct the intended variant you use for. In this case, the chart controls expect that you pass the time format used by the library of user interface, that is, one that is returned by the GetCurrentDateTime or MakeDateTime functions. The underlying C for this representation of the time data type is simply twice, and so it is not a good name to refer to it. That is why I used UIDateTime, but I should have been clearer than that.

  Question: Y at - it a function to convert time_t values UIDateTime values

  Response: Yes. You can use the functions of the programmer's Toolbox following two, in exactly this order:

  CVIAbsoluteTimeFromCVIANSITime (time_t ansiTime, CVIAbsoluteTime * absTime);

  CVIAbsoluteTimeToCVIUILTime (CVIAbsoluteTime absTime, double * uilTime);
