• Incorporate the binary string in the string spreadsheet file

  Hello LabVIEW wizards...

  So I use scripture to VI file spreadsheet to create a beautiful layout, tabs-delimited report of one of my programs for the acquisition of data file. In one of the cells in the resulting worksheet file that I want to put a binary string of all my control values so when you open the data file all the control parameters used for its manufacture are restored, but the string is hidden when the report is displayed in Excel.

  The problem is that the binary string flattened uses tabs and returns as part of its syntax the Spreadsheet File this VI to Write it's going in all directions. Worse yet, I can't unflatten chain when I open the file text because of "corrupt data or unexpected".

  If I concatenate the string flattened with quotes around it she is superb and is placed in a single cell in Excel, but when I open the file in LabVIEW that she is still several elements in the array. I've isolated the binary string using the file VI text reading and got a subset of the quoted string, but it still unflatten correctly.

  Essentially, I need to know how to get LabVIEW to pull a string literal full of special characters into a spreadsheet file and it unflatten. Any gurus what help you can provide is greatly appreciated.

  Thank you

  I suggest that you change the formatting of your chain shipped by replacing the tabs and returns with other characters that are not considered as commands by the spreadsheet functions. Without knowing how you represent your control binary values, I can't offer specific characters.

  If two non-printable characters exist which do not appear in the control data, it's easy: just find and replace tabs and returns with those characters.  If there is no character, then something more complex needs to be done for example to escape special characters.  Or create two subVIs - one to remove the tabs and returns before writing the string in the file and the other to restore after reading.

• Ascii to binary string string conversion

  Hello

  I am fairly new to LABVIEW but now I connect to a device using a serial RS232 cable.  In any case I use VISA read to get the output of the unit, and I wanted the device to return the output to ASCII format.  He is able to do, but now I'm stuck.  Now, I'm trying to convert this string of ASCII characters to a binary string.  In other words, if my release was a "Medley" of VISA Read, I have to be able to get a string that was '0111000101101110 '.  Any help is appreciated.  Thank you.

  This does not make much sense, because "0111000101101110" would be "SB" and not "QN". You want to throw a conversion 'lowercase' too?

  In any case, here's a solution that works with any length of string.

  

  This seems quite complicated. In general, it is easier to work directly in binary strings rather than binary to ASCII format.

• little binary string in array (of TCP read) to the table of Boolean LV (and back)

  I would like to ask what is the easiest way for the next conversion? We use aTCP Read function to read an incoming binary string to a S7 API using LabVIEW. We know that LabVIEW stores a Boolean value to 8 bits. The incoming binary string contains 14 bits (representing 14 indicators of status). What is the best way to convert these values of 14-bit LabVIEW Boolean table?

  In addition, we send a LAbVIEW Boolean table in the PLC data (to write a TCP) string containing status bits.

  Thank you very much!

  Martins wrote:

  This 30 bytes contains some data more, including 14 bit flags (size is 14 bits). Since the PLC cannot put 'together' (16-bit) words at his side before sending data TCP, 14 bits is padded with 2 bits holding no valueable info.

  Then the solution is simple.  Take your 2 bytes and unflatten in a U16.  Then use Boolean table number.

• By the way the table of Clusters with binary strings via adapter LabVIEW

  I need to go through LabVIEW adapter table clusters containing binary strings.
  These data will be subsequently stored in the MySQL database.

  I need to force the option "Binary string" for the ValBinary element, even if my output array is empty.

  Is this possible?

  Used versions: TestStand 4.2.1 + LabVIEW 8.6.1

  Attached file: valbinary2.vi containing the clusters of test output array.

  Howdy Jean-Louis,

  My apologies, I'm not quite your question. You're right that LabVIEW does not know that a string is a binary star strong; LabVIEW, chain stores in a format of Pascal, looks like all the strands in the same way. Because TestStand stores strings in the C type format, on the other hand, the null (0x00) characters can be confusing when interpreting strings in TestStand as you learned to understand. That is of course why TestStand offers the feature to interpret strings as binary strings.

  As Sylvie refers to his post, to illustrate his point I created within TestSTand an array of the same type of data customized to store past out of your valbinary.vi of test data. Test patterns, I also edited the outputsome constant values to the cluster VI. (See the following screenshot). Note that the last string (named ValBinary) in the cluster contains a hexadecimal string with a null character that is inserted as the 3rd on-screen character (before the actual end of the string).

  

  Here is a screenshot of the created sequence file that calls the VI and then displays the number of items in the table from the VI to the user.  Note that the Locals.MyTestData table is empty before the execution of the sequence.

  

  Finally, as the execution of the sequence, I opened the Variables pane to view the contents of the Locals.MyTestData table. Here, I have confirmed that the "binary" string of LV was successfully passed in and stored by TestStand.

  

  Finally, the popup message in the second step of the sequence shows indeed a message indicating there were two elements in Locals.MyTestData.

  This sequence has been able to run successfully even without manually specifying a size of Locals.MyTestData beforehand. TestStand dynamically allocated the necessary elements to store the results of test valbinary.vi.

• Get the binary content of a file

  Hello

  can someone help me get the binary content to the format string of any file passed as an input.

  IM new to the Blackberry Java development so please help me with this.

  Any help would be appreciated.

  Thank you & best regards

  I found the solution.

  I used two different functions to get the binary and hexadecimal representation respectively

  These two functions are:

  
  // function that returns binary data of file
  
  public String getBits(byte b)
      {
          String result = "";
          for(int i = 0; i < 8; i++)
              result += (b & (1 << i)) == 0 ? "0" : "1";
          return result;
      }
  

  // function that returns hex data of a file and writes it to another file
  
      public static String byteArrayToHexString(byte[] b) {
  
          int len = b.length;
          char[] s = new char[len * 2];
  
          for (int i = 0, j = 0; i < len; i++) {
            int c = ((int) b[i]) & 0xff;
  
            s[j++] = (char) HEXBYTES[c >> 4 & 0xf];
            s[j++] = (char) HEXBYTES[c & 0xf];
          }
  
          DataOutputStream os = null;
          FileConnection fcon = null;
          try {
  fcon = (FileConnection)Connector.open("file:///store/home/user/hexfeatures.txt",Connector.READ_WRITE);
  
              fcon.create();
              os = fcon.openDataOutputStream();
              os.writeChars(new String(s));
  
              os.close();
              fcon.close();
  
          } catch (IOException e) {
              // TODO Auto-generated catch block
              e.printStackTrace();
          }
  
          return new String(s);
        }

• Extract strings in the tdms files and write the strings in the file txt or lvm

  Hi all

  I'm struggling to extract strings from a file of tdms to write them in a txt file.

  The strings were written in tdms is a time stamp data recorded to a compact RIO.

  I put the chain in a different group from the PDM, but when I use the function read tdms with the group name, as I said, an error message is always take place.

  Thanks for all the help.

  PS: I have attached an example of tdms file I got over here.

  Kind regards

  I tried your attached file and it seems that everything goes file. I have attached the screenshot of my VI here, what do you want?

  

• How to parse a binary string

  Hi people,

  I read a binary string to a Sonic anemometer of campbell. It is transmitted via RS 232 9600 baud. The problem is the following:

  I read the entry stamp from time to time (all 300 ms). The outpit of the sonic is much faster (every 30ms). There is only a certain amount of stored bytes I've read. To get a correct value, I find 2-byte endpoint AA HEX and HEX 55. A complete sentence consists of 12 bytes 10 bytes each endpoint U8 values and 2 bytes. How to search for them?

  My idea was to see how many bytes, I read, convert each in a binary table and then show them as boolean table all together (see annex VI). It works but I can not find the expression just binary AA Hex and 55. And it is as interesting as the first column (bit 0) and last (bit 7) always remain 'false. ' I'm doing something wrong?

  So it would have been more useful if you would have posted the example that has been read data.  Because I didn't have everything I've done a few.  The attached VI will look for places where the hexadecimal byte AA then 55.  It then divides the sections of data using this information.  I wrote it two ways because I was typing this I thought of a better way that uses string functions to break the data into a data table.

• How to convert the binary value to a binary string in labview?

  Hi all

  I need to convert the binary value to a binary string. We have decimal or hexadecimal or octal number to decimal string, hexadecimal and octal string

  Hi pgm, use the function 'Format to a string. See the attached example. "%b" is the binary number in number in string format specifier.

• Display the exact string of the file as a hexadecimal display data

  I'll send control messages via a serial port, which are built in a series of bytes.  Currently, I have all these messages in an excel file which is 8 columns of 224 lines.  The messages are the exact hex display, I need for my program works.  To check my installation, I tested a few messages by manually typing in messages using a string constant and the value display hexadecimal and everything works well.  How can I get the strings in my file to be recognized as they use hexadecimal display.

  Thanks for your suggestions.

  So if I understand, you read an ASCII representation to hexadecimal format of the command strings.

  You must convert ASCII bytes, then the chain, in this way:

  

  The entrance on the left string must be read from your file, of course.

  Notice that the representation of the integer constant must be U8.

  You don't need the Trim function spaces if you are sure that the string does not contain additional characters beyond the last hexagonal number.

• How to save the string in a file with some special characters

  Hello

  I m using MD5 - llb to create a password.

  So, I want to save this MD5-string to a file and read it later abd compared again.

  Works perfectly with a proplem:

  Some Word create a '\r' in the string of MD5 and when I save this string in a file and read it at the time its read as a '\n' for the comparison does not work.

  My question is: How can I record a string exactly as if it were somewhere and read back (also the invisible characters)

  For example, the word: heinz

  is in MD5: \r\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95 (string as display codes indicator)

  When I save the string in a file, then I rerad back: \n\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95

  I used the "write text file" and "read text file".

  What should I use to record and play back the same thing?

• Research within a tree of files for a string in a file

  Okay, I give up...

  I'm trying to search for a particular string like "xyz" in a bunch of files in various places in a tree *.txt - all folders and files in that I want to search are rooted in a particular folder.

  It used to be that Windows Explorer has a "Find files and folders" feature that had a "Search subfolders" box was just very well worked and intuitive.

  However, with the new improved search facility, I can't it to search for a string in a file tree. And assistance does not help.

  I even went in search, typed in "*.txt" for the name, and the search string, I get "name of xyz: * .txt" and the string is not found, even though I know that it is located in at least one of the files in the file tree under 'place' which is like C:\apk

  Could point me to it someone please to a description of how to do this, or maybe a pointer quick as to what I'm doing wrong?
  Thank you!

  Hello Paul,

  The syntax for Windows Search is now quite different.  On the one hand, the jokers work differently and are rarely needed for common searches.  Try instead to use the ext property:

  XYZ ext:txt

  However, remember that Windows Search is now based on word, not on the character.  When you search the contents of the file, if the string "xyz" is in the middle of a Word, it can not be found unless it is preceded by a space, an uppercase letter or a punctuation character.  Thus, you may need to perform a search on part of the word preceding the string "xyz".

  There is good information on the new syntax of search here:
  http://www.Microsoft.com/Windows/products/winfamily/desktopsearch/TechnicalResources/advquery.mspx

  Regarding the search for subfolders by default on Vista, the option is set in the search window "Folder Options" tab dialog.

  Some other tips:

  Remember that the parent folder is set to be indexed in the Indexing Options dialog boxes.

  Be aware that the type of search you do is preferable to Windows Explorer or the main search box, not in the start menu.  The latter has its options, which are often more restrictive than other methods.

• inDesign SDK CS5.5 - deprecated conversion of string constant in "tank."

  Hello world
