• How to write data in mode intertwined with TDMS C DLL 2.0?

  Hello

  How to write data in mode intertwined with TDMS C DLL 2.0?

  I use DAQmx features in Visual Studio C++ without Measurment Studio.

  This function returns the data in interlaced mode.

  How can I configure the functions of DLL C TDMS to store this data in the tdms files?

  I see that it is not possible with the PDM version 2.0 with 1.0.

  Thank you

  -TDM C Dll is not able to do

  -TDM header writer may be usable for this but is not able to be used for tdms files.

• Save and write data from table to table - easy

  Hello

  I got this system delivered to me. I'm new to LabView and just save the data from the table "average voltage" (inside the while loop) to do some additional testing of our product.

  I will like to do similar to this.

  (1) save in excel file.

  (2) save only when a button button and save it then 5 ilteration.

  (3) save and manipulate the data, so it is displayed in 6 columns (each LED 1) instead of 1 long colum.

  I tried different things with structure business T/F, which resolved the buttom-request. But I am in doubt I should use, writing to the file of the measurement or write to us to the worksheet (by using labview 15.0)-delimited according to my offer the best possible?

  He also seems to be too much to handle when I try to write in txt file, because it pops up with and error that I do not know how to fix, but it says this:

  Error-200279

  Possible reasons:

  The application is not able to cope with the acquisition of equipment.

  Increase in the size of buffer, most frequently the reading of data or by specifying a fixed number of samples to read instead of reading all available samples would correct the problem.

  Property: RelativeTo

  Corresponding value: current playback Position

  Property: Offset

  Corresponding value: 0

  Task name: analog channel

  Thanks in advance

  I agree with Taki, but want to make some additional remarks:

  • LabVIEW is a data flow language.  Think of the "flow" of your data.  You talk about "save only when a key is pressed" and a finite set of data.  You are collecting before the press the button and everything just do not save?
  • Data are collected at some rate, and likely, you don't want to "Miss" data points.  This means that you shouldn't do anything in the loop of the Collection that takes a long time.  If your recovery rate is low and your treatment is fast, you can have everything in a single loop.  Otherwise, to use the technical stream (producer/consumer is a good) to process the data in a single loop in parallel with the collection in a loop independent (and asynchronously).
  • How do you write your data?  You want to write "on the fly", as it is, or can you wait, collect everything, any format and then write it "all at once"?
  • What do you mean by 'save the file in Excel?  Do you mean a 'native' Excel file, one with the extension .xls or .xlsx?  Do you mean a Comma-Separated Variable (.csv) file this reading peut of Excel (and, indeed, usually registers itself to read, change the icon of the .csv files to "look like" it is really an Excel file)?  If the first case, I recommend using the report generation tool.  But for the latter, you can also use write delimited spreadsheet, which can be easier to use.

• write data in table 2D

  Hello, I am writing my data flowing in table 2D. I have attached a sample vi. What is the problem is that:

  As the block diagram shows, there is a 2D array whose first column has given fixed. Here's the 1,0.977,0.955..etc. These are my constant values X. The problem is on the writing of values Y in the second column.

  First of all, I run the program, it runs and I stop, so we calculate an average value because of the "magnitude and level Measurements.vi. So I want to write this value average to 2. line in 2.column. Then I push the pause button twice and the program continues again and stops. So I want the program to write average data of this stage in line 3. 2 column and so on. I want also to the value of 1 line. 2. constant zero column. However, after each loop is executed, the average value is always crushed by 1. row of 2. column. The other rows of 2. column are always zero. So, I want to like this;

  1             0

  value of the first run of average 0,977

  the value of the second run average 0,955

  average value of the third execution of 0,917

  0.88.. .and so on.

  0.842                          .

  0.767                          .

  0.692                          .

  0.617                          .

  0.504                          .

  0.391                          .

  0.278                          .

  0.165                          .

  0                                .

  After obtaining table 2D it liked, I will trace the XY graph and then curve fitting. My original vi cannot be fully open so I have attached a sample vi. Could you please help me as soon as possible?

  
  

• Write entries of similar continuous strain of spreadsheet with headers

  I use a cDAQ-9178 chassis with a NI 9235 strain gauge model to collect the analog inputs of the strain of 3 gauges. I currently have a program (see Finite_Strain.vi) that collects the data and writes it into a spreadsheet. I would use continuous instead, sampling so that I can see my curve of deformation-time develop as I run my tests. I wrote a program that does this (see Continuous_Strain.vi) but I'm unable to write data to a spreadsheet. I am currently using the function "Export to spreadsheet File.vi waveforms" as opposed to the function "Write to File.vi worksheet" to write my data in a spreadsheet because it allows me to have data headers and a time column.

  My problem is to store all data in my loop. How to build a table of all these data outside the loop and write to keep the worksheet column headings?

  Any help on this problem is greatly appreciated. Thank you

  You can do it.

• How to write data in an Excel spreadsheet protected (with unlocked cells)?

  Hello!

  I have LabVIEW 8.2 and I often use the report Generation Toolkit for Microsoft Office' to save data in Excel spreadsheets. So far, I only used the leaves unprotected.

  But right now, I have an Excel worksheet protected by some cells unlocked. If I open the file using Excel I can fill these unlocked cells without any problem. However, I am not being able to fill these cells unlocked using LabVIEW and the Toolbox. I have a few questions:

  (1) is it possible to use LabVIEW to write data in a protected Excel worksheet, even though she has unlocked the cells?

  (2) if it is possible, how can I do that?

  OBS: I noticed that if I unprotect the sheet, I can write data to the file. But I don't want to be protected and the protection of the sheet, since users will not have the password.

  I hope that I was clear. I really appreciate any help you can provide.

  Thanks for the replies.

  Use ActiveX I could write the cells individually. By doing this, I could write in the unprotected cells without any problem. hour

  Probably, the Toolbox has been activated somehow the overall protection of the spreadsheet and Excel was not allowing writing.

  I had never used before ActiveX, so I had to learn it from scratch. I was looking for some tutorials on the internet but I have not found much information easy. What struck me the most help is an example that comes with LabVIEW named "Excel - write Table.vi. After some tests, I was able to open my data protected from the worksheet and fill in the unlocked cells.

  Thank you guys!

• Unable to get the elements placed at the top and bottom of the cell of the table with vertical-align

  Hello

  I have a three-day educational courses in the list table. In each cell, I have the title of the presentation at the top with the name of the speaker below. Because some titles are longer than others, the line grows (rightly) as longer securities are covered in Word. So far so good. Now, I want all the titles to always start at the same distance from the surface of the cell (I use padding 2px) and names of speaker all be equidistant from the lower border, (i.e. 2px).

  I tried to place the title elements with < span style = "vertical-align: top" > </span > presentation title

  and the name of the speaker as < span style = "vertical-align: bottom" > name </span > Speaker

  and I tried the same method with < div > and < p > tags. Items don't move. Can someone tell me how to make the names of the speakers will be all aligned at the bottom of each cell?

  Here is an example of the code table I've tried:

  (Thanks!)

  < table style = "text-align: center;" do-family: Arial; background-color: #f7d49c; "border ="2"bordercolor =" #467E9F "cellpadding ="2 ".

  "cellspacing ="0"width ="900">"

  < tbody >

  < b >

  < td width = "300" > < span style = "" vertical-align: top; "> This is a short title </span > < br / >"

  < span style = "vertical-align: bottom" > name </span > < table > Speaker

  < td width = "300" > < div > is the title of another presentation, which is really long because some of the presentations have titles like that < / div > < br / >

  < div style = "vertical-align: bottom" > Speaker name < / div > < table >

  < td width = "300" > < span style = "vertical-align: top" > This is yet another presentation with a semi-long title </span > < br / >

  < span style = "vertical-align: bottom" > < table > </span > Speaker's name

  < /tr >

  < b >

  < td > < table >

  < td > < table >

  < td > < table >

  < /tr >

  < b >

  < td > < table >

  < td > < table >

  < td > < table >

  < /tr >

  < b >

  < td > < table >

  < td > < table >

  < td > < table >

  < /tr >

  < / tbody >

  < /table >

  By default, the content of the table cell is average aligned.  You need not do anything.

  If you want your cell vertically aligned up or down, you can specify it in your CSS.  These effects all the text inside the cell.   It's all or nothing.

  Some text that is aligned at the top

  Some bottom-aligned text

• How to transfer data from the data in table 2D only once file?

  Attached file will write same data in table 4 times 2D file. Output must be in a table 2D.

  Someone will provide a solution or a reason to explain why the data are been ouputted 3 more times? Thank you

  I already told you a better and more effective method. The function of reading worksheet is on the exact same range as your text file and does everything for you. If you insist for some reason strange kernel to reinvent the wheel and write your own code, take the correct path. The use of 4 separate spreadsheet String to Array is the cause of your problem and I already said too much. Don't you think that get you 4 times the data is in correlation with the fact you are using 4 times the functions necessary at all? It is simply not true. Look at the diagram-writing block on a spreadsheet file.

• error when pass array 1 d by data in table pointer via Labview-built c++ dll

  I'm trying to generate a Labview VI to a DLL and let it be invoked by vc ++, by which a 1 d array is passed. However, I can't generate the DLL when you use the data pointer to the table, which gives the error like below:

  [ERROR]
  Code :-2147221480
  Strengthening of the DLL.
  Error when compiling the DLL as a function name or a parameter is illegal. Check function and parameter names are legal C identifiers and are not inconsistent with the LabVIEW headers.
  Additional information: 9 project link errors
  Type Library generate error. MIDL.exe failed during the compilation of the odl file used to create the type library.
  Note: The error indicates that the odl file has unknown types. This error is possible when
  works with non-standard types is exported using the method qualifier exporting files in
  release the configuration that have not been recompiled during the build process.

  The Prototype of VI define is as below

  

  But, if I use the pointer to manage through the table, the generation is successful, error-free. I write something to call the DLL built labview, which basically reads 1000 double the data of an instrument.

  #include "TestDQMaxDLL.h"
  #include 
  
  using namespace std;
  
  int main(int argc, char** argv) {
      cout << "Start testing DQMax DLL" << endl;
  
      int leng{ 1000 };
      DoubleArray rawDPData = AllocateDoubleArray(leng);
      test_dqmax_dll(&rawDPData);
      cout << "Successfully invoked the DLL!" << endl;
      cout << "DoubleArray.len: " << (*rawDPData)->dimSize << endl;
      for (int i = 0; i < leng; i++)
      {
          cout << (*(rawDPData + i))->elt[0] << "\t";
          if (0 == i % 10)
          cout << endl;
      }
  
      system("pause");
  
      DeAllocateDoubleArray(&rawDPData);
  }
  

  But the printed results are not correct.

  My questions are:

  1. why cannot generate DLLS with the data of table pointer. In this case, the argument of the function is as simple as a double array.

  2. for table handle pointer, when the resutls are incorrect and how to get the good ones.

  Any comments would be appreciated.

  BTW: I use Labview 2012 with Visual c ++ 2013 on Windows7 64 bit.

  I never needed to pass a table of LabVIEW handle external code. Search this forum for posts of RolfK, it is most likely to have posted such an example. I recommend that you keep things simple and remodelling your table a table 1 d 2D before moving on to external code and manage as a 1 d table (it's just a little extra math).

  Sorry I don't have a solution on why you can't build with a 1 d as a pointer of table table. If you post your project I'm happy to try to build (I'm on LabVIEW 2012, however), but as you said, it will rely on another machine, it seems more likely to be a problem with something on the specific computer where there is a problem.

• Save the data on the button and then save the data on a spreadsheet on another key.

  Hello

  I am a new user of Labview. I'm developing a Labview 7.1 program that will record data on the keys. Another button, he must stop recording, and then open a file dialog box to save the data stored on a worksheet. I read in this forum that I have run several loops in parallel but unfortunately I can't see the examples because I use an older version of Labview. I tried to do to pass the data in a table, once recording is started, and then I carry the data to write a function that spreadsheet inside an another case statement. However, once I put the writing on the spreadsheet for the case statement he cannot write. I tried to put out the statement box but it save only a single set of data. Sorry if I am not clear with my explanation. It will be greatly appreciated if someone can give me some advice on this.

  Thanks in advance for your information.

  See you soon,.

  You want to build a table of data.
  If the Boolean value is true, you will add a data point in the table.

  If it's wrong, you do not add anything, and the loop will be re-iterate.

  In the example below, the same code appears twice.

  Half top shows the case of 'Real' and the bottom half shows the case of 'false '.

  

• Spreadsheet with 3 columns

  I have a table 1 d with 'X' of data and a 2D with "Y1" and "Y2" data table, and I want to export to a spreadsheet, in each axis in a column.

  Is the best way to add each table to the spreadhseet, one by one? If this is the case, how should I do that?

  It may have already been posted, but I couldn't find anything in the title of this topic, sorry and thank you.

  Add your table 1 d to the appropriate column of your table 2D using 'insert into the table.  This will give you a table 2D containing all your data in columns.

  Write the table 2D resulting in your worksheet in a single shot.

• Qosmio X 500 does not write data to any CD

  I have a Qosmio X 500 with windows 7 (64-bit) home about this, my CD-Rom used to work fine, now it reads and serious DVD and blue-ray, but it will not read or burn CDs.

  I have no more or less than the registry filter.
  How can I solve this problem?

  Hello

  Have you tried different CDs from different manufacturers?
  Try the CD R TDK.
  I use this kind of CD and never had any problems, but had problems to write data to the other CD.

  In addition, you can try to clean the laser lens you can use a piece of hydrophilic cotton and a very small little alcohol which should be good enough.

  By the way: fire what app do you use? In my opinion Nero is great software, one of the best software in this segment.

  I'm off today and I have no available LabVIEW.  I'll look in @ Thursday.  I bet others will fight for a solution.

  Well, well, well!  Once the ball 8 missed by a mile!  Nobody went to the city and got jiggy on the problem!  It really was a fun little vi to write.  I'll start with a tease: Code captures (Backsaved to 9.0 because this not depend on features that have not been around for a very long time) to follow in a spoiler.  For those playing the game for fun and games, duplicating the code without looking at the backdoor.

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
