flatten channel adds the length of the string

Hi all

I flatten a cluster chain help to flatten to string.vi. The cluster contains strings and arrays. The flattened string contains the length of the string that is appended to the string.

So if I have a cluster with only 1 string and a value = "LabVIEW". the flattened string would be "0007LabVIEW". Flatten channel vi has a Boolean entry "add string or array of size? even if I set the Boolean value false, it always adds the length of the string. Is this a bug?

I think that if you read the detailed help to flatten it to string function you will see this is not a bug.  That boolean applies only to top-level data, once put you something in a cluster or array, the Paris are open.

  • Add the string '& lang = en '.

    I would like to add the string '& lang = en' to the path variable.

    < cfset newpath = path & "& lang = en" > ".

    < cfoutput > #newpath # < / cfoutput >

    The output is

    index.cfm < = en

    but not the desired output

    index.cfm & lang = en

    Help, please.

    There is a good chance that the exit IS 'index.cfm & lang = en', but your browser is to choose of does not display it like that.

    View the page source to confirm this.

    Short strings like the one that begins with an ampersand symbol (and) are often considered a character encoding on browsers.

    Alternatively, you can force the browser to display the string in the way desired with functions htmlCodeFormat() or htmlEditFormat().  Which, oddly enough, must be able to encode special characters such as the ampersand.

    I.E.

    #htmlEditFormat (newPath) #.

  • size of the string channel

    Hi all

    I have worked with a channel with the String data type and fill in the values with a script. This channel is really big, there was more 4 000 000 values long a few times. It worked perfectly fine last week. When I tried to run my script today he woud throwing an error the 262145 index is outside the valid range for the property values.

    Digital channels works well and I has not changed anything in the script related to my channel.

  • IMAQ flatten image for the 64-bit version of string

    Hello

    I noticed customer odd based on vision "flatten image chain" on labview 64-bit edition. In my program I use flatten image to the string (with compression to JPEG and kind of flatten Image) to compress and send data to another application. I noticed on the compressed image color missmatch. I say red (255,0,0) 32-bit RGB image and I flattened for string and then save this string as a binary JPEG using Write to vi. When I open the file of the picture is blue (0,0,255). It doesen't matter how data is written (big endian, little endian or native) the result is always the same. 32-bit edition Labview, the code worked correctly.

    I reported a bug in the NC and I'm still waiting for a solution to this problem.

    LabVIEW: labview professional development system 2010 32/64 bits (with vision development module) completely v10.0f2 lie

    Systems: labview 64 bit on windows 7 64 bit-> flatten image to string-> false color

    LabVIEW 32-bit on windows 7 64 bit-> flatten image to String-> colors OK

    LabVIEW 32-bit on windows 7 32 bit-> flatten image to String-> colors OK

    A picture of the block diagram that I used to test the conversion is attached.

    See you soon

    Hi 3DVision.

    I think I see the problem... you code looks like he expects that out of "flattening the image of the chain" will actually be a JPG file as a string, because you have chosen to use the JPG compression options. However, this is not the way that VI is intended to be used. It is simply a way to convert an image type of Vision in a string representation which can be easier to haul around (for example via the network, the user file format, etc.). It is a parallel to normal 'flatten' that can be used on any type of data from LabVIEW. The format of this string is the owner and has provisions for storing information that is specific to the Vision images that cannot be represented in the file formats normal image (overlay information, benchmarking, custom, etc. data info). If you are save the string flattened in a file and expects to open as a normal JPG file, it is unlikely to work properly. The only way that it would be guaranteed to work is if you switch to the corresponding VI "unflatten chain. I don't know why it works in 32-bit mode, but it sounds like a lucky fluke.

    For your use case, you probably want to use the VI "IMAQ write the string. This does not give a result string that is identical to the specified file format.

  • How to get the length of the string a vm?

    find the number of channels and if greater than 8 consolidate them.

    }

    Someone has this practice? or something else?

    I'm in a cloud environment vSphere 5.5, installed latest powercli.

    Thank you

    Don't know why this does not work for others, but what I posted before work for me.  Here is a more complete version of how get the those of VAPP VM.  There are no doubt more direct ways, but that how I made it so far:

    1. get the VAPP

    $vApp = get-CIvApp-name 'Test-VAPP.

    2. get the VMS of vApp

    $VMs = $vApps.ExtensionData.Children.vm

    3. get the ones for the VM first in the list of $VMs:

    $VMs [0]. VCloudExtension.any.VirtualDisksMaxChainLength

    This last command returns 18 for me which is the "Length of the string" value in the properties of the Virtual Machine to the virtual machine in the vCD UI.

    I hope this helps.

  • First Max value to find and add the previous channel values

    Hello, I would like to be able to parse a string to find the first maxima (inflection point) and then add channel so that all the values are equal to the maximum

    the index where the maximum was found.

    To explain better, in the attachment, the original channel's Ych and the channel in the annex is Ych_appended.

    Any help would be appreciated.

    Thank you

    The feature you're looking for better using the SCRIPT of DIAdem.

    First of all, you can find the first maximum in a channel by using the ChnPeakFind function. The document below explains how to use this:

    http://digital.NI.com/public.nsf/allkb/DD069B95FB938C4286256FC8006A09CD?OpenDocument

    The channels that you specify in the function call will contain the value x and y of the first maxima. Then, you will just need to:

    1. Copy the original using ChnCopy channel.

    2. Find the index of the value to your channel original x axis at which the peak occurs.

    3. Browse the newly copied channels, replacing the inside with peak values until you reach the index of the value found in step 2.

    I hope this helps.

  • TDMS read fails on the channels of different lengths

    Experts in LV...

    It seems that there is an error in the PDM to read functions.   I have a TDMS file generated by a built executable, this file has a group of 9 channels.  Channel 5 is data taken at a higher rate (IE 20 MHz) compared to the date in the other 8 channes (1 Mhz).  1 Mhz channels have 110 000 points, of course, the 20 Mhz channel has 2 200 000 points.

    If I read this by using the playback feature TDMS passing an array of the names of Channel 9.  It runs and returns a table of 9 waveforms with Y0 dt values correct and the correct.  However Channel 4 (the 5th string, that long) a garbage in the data for all points since the stop the 110 000 in other channels.  This trash is as numbers-10 ^ 304 and zero.  The first 110 000 points are correct.

    The file itself is not damaged.  If I read the file in a loop 1 channel at the time, and to build the table of waveforms I get all 9 waveforms and the correct data of variable length.  A trivial example to read the actual data file is attached with the data file (I hope that boards that leave be attached).  Intrigue albums has corrupted data to read it all-in-one and the bottom has the accurate version of loop data.  The waveforms of tables on the left show that corruption occurs precisely at the location 110 000 table where the other tables

    Yes, the data file is too long for the forums.  You can get the program file and the simple example data

    TDMS error.zip

    No Council or if it is a real mistake.  I don't see anything in the documentation that I'm doing something wrong.  The fact that it returns a length of valid array and no error code is leads me to believe it's a bug of LV.

    Hi sth.

    Thank you for your results. The issue you reported is for playback of several channels of scaling in staircase once. (PDM read on several channels in staircase of unscaling works very well). The .tdms file, you provided, including the scaling of the data.

    I can give you two workaround solutions. The first is what you mentioned, read each channel of scale inside a loop. The second is that always read all channels once, but rank all length strings in descending order. (The first is the channel with a maximum length; the last is the channel of a minimum length).
