Concatenate the series of characters


I need a function to concatenate a set of characters.

The function CONCATENATE string does not work because I only have a single entry, as I said it is a series of characters...

I want something like!-R-1-0-V-5-0-$-\n to become something like! R10V50$ \n

I tried to make a loop with registers at offset but it is another problem, I don't know how many characters it will be, I want it stop when it detects an \n char

Have I not to worry about the time?

Thank you

  • The analysis of the non-numeric characters in a string


    I am communicating a robot to LabVIEW (2013) via TCP/IP and sockets. The robot is the server, and LV is the customer.

    I start with the target data in this format (in a string):

    "[0 ~ 100 ~ 0] ~ [0.96593 ~-0.25882 ~ 0 ~ 0] ~ [1 ~ 0 ~ 0 ~ 0] ~ [150 ~ 50]."

    [X, Y, Z], [Q1, Q2, Q3, Q4], [C1, C4, C6, Cx], [TCPVel, OrientVel] except replacement ',' (comma) with a ' ~ ' (tilde) because I load the target data in a spreadsheet which is a comma-delimited file.

    In LV, I take this string, the analysis of the chain and split individual items. I then pulled the singular elements as unique, 32-bit of real numbers. I take each one and convert them individually to a string, concatenate them and send them to the robot. The robot decompresses these raw bytes individually and converts them to a target of robot (position in space).

    I train (BT) check if the user has sent a bad character (non-digital) in the target data. Example of this is:

    [- 50 ~-150 ~ 0] ~ [0.96593 ~-0 ] [B2has5D882 ~ 0 ~ 0] ~ [1 ~-1 ~ 0 ~ 0] ~ [150 ~ 50]

    Now in BT, when I'm scanning the chain, these bad character becomes the entire element to zero and everything else then to zero as well. See attachment for example screen similar.

    My question is, my VI, I can analyze all non-numeric characters (that are inside the parentheses and characters that are NOT a ' ~ ' (tilde))? In this way, I can always get this item numbers and do not have this element or other items turn to zero?

    Thanks in advance for any help!

  • Does anyone know if you are limited in the number of characters in the text field?

    I have the scrolling text of the distant rear side right up to the edge on the left front. I only get to halfway through the message of full text and letters are mixed at the any end. is there a limit on the number of characters I can use? Is there a setting a limitation I can increase?

    It seems to be. I figured it at approximately 16000 characters more or less (or even lower). (Estimated from the original character TextEdit limit as it seems to be this type of core service text text handling in movement and FCPX.)  I drew this conclusion during the development of a method to create a movement subtitles. It finally turned out that I had to cut the scripts into pieces 'chapter of size' to keep the character countdown. I never got to finish this tutorial and it has been quite some time now (and I can't not find my notes on the subject). It could be that the number of characters estimated is actually lower.

    There is no way to reset the limit.

  • Update the series/model number in the BIOS (ThinkPad 2nd Gen Helix)

    Hello! I have a ThinkPad 2nd Gen Helix (model 20CG000QUS), I replaced the motherboard in (because I'm with a Lenovo authorized service depot), but I'm unable to update the series/model number in the BIOS. I tried the utilties USB and bootable diskette and nor will not work (I can't boot from either one sense). This is despite me turning off the Secure Boot option in the BIOS. When I enter my credentials for the key to maintenance/diskette, I find the download ok in, but on the page for the supported systems for this key maintenance/diskette, the Helix model I have is NOT LISTED. I tried to update using other utilities and I get the words of INVA LID, and I can only replace the "LID". So, basically, I'm stuck.

    Any suggestions? Thanks in advance.

  • I have iPad 2version 8.4.  Should I switch to 8.4.1 before moving on to the series of the 9.0 version?

    I have not updated my iPad to the latest upgrades of version 6. I currently have version 8.4. Should I update the 8.4.1 version before moving on to the series of the 9.0 version?  Going to miss any important settings or changes if I go straight to 9.0? If everyone advises me to install all the missing versions, please can you me where I can find them?  I already know where to install version 9.0 and 9.2.

    1. No, and you can't.

    2 No.

    3. If you somehow find and force - install any intermediate version iOS, iPad will not turn on.


  • How to analyze the data of the series?

    Hi, really new to LV and I just can't get my head around how to solve this problem.

    I've got about a continuous stream of serial @57600 data transmission speed

    It is composed of 9 signed 16 - bit ints sent big-endian and then stopped with 2 bytes to 0xAA.

    The data are only heard so when LV opens port it can start at any point in the workflow.

    I can open the port, to read, to convert the entire bytes, BUT that I can't run is to know how to "synchronize" my loop to a limit of 0xAAAA

    My simple idea was to throw the stream somehow until 2 consequutive 0xAA bytes and then enter the main loop

    My complex idea was a FIFO with a sort of string or byte array Analyzer in the rematch of the head of the queue model the 0xAA, 0xAA if there is no 18 bytes between the model & the head then throw else remove the 18 & process

    This seems too complicated, especially since the situation is expected to occur only once (I got my loop running for hours without dropping one byte, so I'm happy with it).

    It is, I can't implement either I think I just need a little in the right direction please...

    You don't need a producer consumer architecture. That is right. But it is not so complicated and if you are new to LabVIEW you should familiarize yourself with her rather sooner than later.

    The analysis of the state machine workflow must be in its own loop to do his own thing. As the packets are detected and controlled, they must be communicated to the loop that will do something with it. In this way, no matter what you do with the data now, if it's just the display, save to a file, or whether it is, you can change it later without touching the code of treatment of the series. The code in the loop of the series is just sitting there doing its thing and don't know or care what happens to packages.

    Attached is the code saved to 8.5

  • to limit the input in the xcontrol string characters


    I followed an example online at deveope an xcontrol for the input string, but limit the input only characters for capital letters from A to Z. I have the main code as follows

    In the key to the bottom of the event, I throw all input character with the ASCII beyond [65, 90]. Sounds works but if I continue to press a prohibited (e.g. %), it will show that the key in the control. So, how can I ban the entry by a long press on a button? Thank you.

    Maybe including an event ' key repeat? It will handle the case when a character is added when the user holds the key. I think that you will just need to copy the code in the event "button down?

  • Help using 'save in the series of files (several files).


    My name is Daniel R.

    I am a student doing research internship and was put on a project using LabView (with no experience using Labview).

    I'm using LabView student 2013 version 13.0 edition.

    Now the VI I created is to get data from a PMT using a Rigol DS1204B connected to Labview.

    The problem that arises has been save to a series of files (saving automatically). I intend to take at least 1000 tracks and naming manually, each is not very effective. I have my VI attached, if someone kindly took a peek. I suspect that the problem is her 'write as leader' in the block diagram. I put the option "Save in the series of files", however, when I double click on the "Write to the measure" box, I see that 'Save in a one file' is selected, and after a second, it automatically converts the option 'save in the series.

    I did not have enough experience about why he wants me to name each file, so I'm tender hand for help.

    Advice or improvements on my VI is also appreciated.

    Thank you

    Daniel R.

    Who says we can't dynamically build a file name each iteration of the loop?  I like to use the Format string to add the loop against a string which will be then turned into a path.

  • What do DAQmxSetAIUsbXferReqSize(), DAQmxSetAOUsbXferReqSize() and DAQmxSetDOUsbXferReqSize() on the boards of the series M UBS?

    I have a multithreaded C ++ Builder program that acquires data analog with a wire and output of analog and digital data with a second thread.  The inputs and outputs occurs in blocks of data every 0.1 seconds.

    On the advice of M - and X-Series PCI and PCIe this output is smooth, but on a Board of USB-6259, admission is VERY NERVOUS waiting on every 0.3 seconds or more. This makes the use of USB M-Series cards with my program basically unacceptable.

    In an attempt to reduce nervousness and smooth the input/output of data, I tried to use the DAQmx features

    DAQmxSetAOUsbXferReqSize(), and


    for my USB-6259.  However, the pieces of data and therefore smooth data inputs/outputs, these functions in different values to SUPPOSIDLY decrease of entry and exit to 0.1 second is no. DIFFERENCE OBSERVABLE versus normal code without them.

    My question is: these functions only designed to do something on the new X - Series USB series cards, but not the boards of the series M USB?  And is there a detailed documentation on these functions beyond C DAQmx help?

    Thank you.

    Bill Anderson

    Hi Bill

    I started looking into questions about the USB-6259 and functions of the required size. Since your post I understand you have two tasks at the same time, one is a task of entry and the other is data ouputting. If you could send me more details of your request, so I can look into this again, would be great. You can specify how tasks are put in place, so if you use synchronization, buffering etc so I can look into the issue for you.

    With regard to the questions you have asked.

    (1) these functions are not limited to the X series, so they should work as you would expect, and I was not able to find other problems with these features on our system.

    (2) unfortunately aid DAQmx is the extent of documentation on these functions, even when there is nothing on our system to go further in the functions.

    When you run your program if other programs and applications are open, it can cause treatment slow down, so that bare in mind also. If you run the task, how would this affect the use of the CPU?

    I found a few documents concerning your application which can help you to grow and to develop your code.

  • concatenate the data in 2 tables in a third table as well as in CONCATENATE strings

    Hello. as the title says, I wish to only concatenate the data in 2 tables in a similar third table that concatenate strings don't. All tables should be 1 d. For example, suppose that there is 1 table with the following: 1. 2; 3; 4 and table 2 with:; b; c; d. I would like a table 3 either 1 a, 2 b, 3 c, 4 d. Now this could be done easily with above mentioned concatenate strings, then table construction. but table 1 and 2 have something like 150 items. Rather painful. Any ideas?

    Hold arrays of two strings in a loop for example, concatentate the strings inside the loop and run the result réécrirait array3.

  • How to use the modules of the series and two different bitrates in FPGA mode on cRIO 9075


    I have a project with modules namely NI 9227 (module 1) and NI 9234 (2 Modules)

    1 - my quesition is the addition of a second rate in the FPGA?

    2 - Why is it TDMS connect 6 channels and 4 channels?

    Thank you

    Attached to the project with two screws

    Hello Ihab,

    Sorry for the late response here; just saw this message! If you want to keep synchronized modules then definitely stick with the master configuration and slave for your two modules. Note also that you can taste a little faster with the NI 9234 as your master module (since its time base main internal is 13,1072 MHz instead of the time base of the 9227 12.8 MHz).

    Also, see the tips and information in our troubleshooting guide for the synchronization of the series C with LabVIEW FPGA modules:

    I hope this helps!
