  He is there not a function?

  Non; in fact, the majority of programming languages are hardcoded to the American conventions. But the charge to replace it if necessary is tiny.

  You might have a similar problem, if someone enters a number of thousands separators: '12.500,0' If you replace the comma with a period, "parseFloat ("12.500.00")" Fortunately will read the number, all the way to the next ' invalid' character, which corresponds to the second period. And then he'll "12.5"...

• How to convert string to number

  Hi everoyne, I need to make a program simple calculation of the GPA in 5 classes. Where A, B, C, D, F are the entries for each other...

  Here's what I've done so far.

  

  But it seems that it is not recognized when I assigns numeric values to each letter. So I would appreciate any help. I tested for the release of "GP" and input A (4) = CT. The answer for GP should be 4 x 3 = 12. But I get a number beyond that.

  I'm relatively new to Labview so sorry if this is a stupid question.

  I would like to make a table of the clusters.  Each element of the array corresponds to a single course.  Inside of the bunch, I would have a string for the name of the course, an enum for the grade and a digital for the number of credit hours.  Use an enum for the grade, so you can make sure that the user space only in the values that you no longer the enum is actually a number.  No actual conversion.  Then you just use a loop FOR (autoindexing) including some shift registers to keep your totals, then divide the totals of the year by the credit hours.

  

• OpenScript/Bank of data/how to convert string to int

  Hello
  
  As far as I know, the values read from the database is a type of Sting. Now, I want to convert a character number stored in the database of type int.
  For example, in "Test.csv" I stored the '9' in the column 'Number' character, then I use the following code to read the character and convert an int in one:
  getDatabank("Test").getNextDatabankRecord ();
  String Testnumber = "{{db." Test.Numberr}} '; Info (Testnumber);
  int number = Integer.parseInt (Testnumber);
  
  However, it seems this does not work, because he says "basic unexpected failure caused by: NumberFormatException occurred." For the input string: «{{db.» Test.Numberr}}.
  I think that this error can be caused by the conversion of character '9' int 9.
  Can someone tell me how to convert a character to be read from database in an int?
  
  Thank you very much!
  
  Kind regards
  Angyoung

  Hello

  You can use the same approach. Use eval()

  getDatabank("Test").getNextDatabankRecord();
  String Testnumber =eval("{{db.Test.Numberr}}") ;
  info(Testnumber);
  int number = Integer.parseInt(Testnumber);
  

  Kind regards

• Whole singed to hexadecimal string to number converter

  HI guys...

  I want to convert the number to hex string to number converter but when I connect integer, otherwise it does not change the value (as if you write 'EC78' you should get "-5000", but I get the value in the range of 60 thousand ")...

  Any ideas?

  Thanks in advance...

  MADO...

  Hi Eric,.

  clearly, the OP asked for signed integers!

  Use this approach:

  ,

  It will mean by '-' 5000 for your example EC78h...

• How to convert a large number to the spell without truncate to 32-bit.

  I'm trying to convert a hexadecimal number (string). The number is truncated to 32 bits, which is not what I want. For example, the number 28037546508295 (double) must be 0 x 198000000007. LabVIEW truncates and the resulting string is 0x7FFFFFFF, using number of Hex String.vi. I'm stuck. Thank you.

  'Number of hexadecimal string' accepts only data of I32. So, you should see a red dot of coercion when you connect your floating point number.

  You must use "Format of value" (also in the String > number of rope/coercion-pallet) and use '%x' as a format string.

  hope this helps,

• How to convert string input streams

  Can someone tell me how to convert string input streams...

  There are multiple ways. I will list down few of them.

  With the help of the old solution and standard java.
  

  publicstaticString fromStream(InputStream in)throwsIOException {    BufferedReader reader =newBufferedReader(newInputStreamReader(in));    StringBuilder out =newStringBuilder();    String line;    while((line = reader.readLine()) !=null) {        out.append(line);    }    returnout.toString(); } returnsb.toString();

  If you use Google-Collections/guava-

  InputStream stream = ... String content = CharStreams.toString(newInputStreamReader(stream, Charsets.UTF_8)); Closeables.closeQuietly(stream);

  If you use the common Apache library... then it is worthwhile.

  StringWriter writer =newStringWriter(); IOUtils.copy(inputStream, writer, encoding); String theString = writer.toString();

  Quick way but only work during deserialization.

  String result = (String)newObjectInputStream( inputStream ).readObject();

  Note: ObjectInputStream is on deserialization and the flow of data must respect the Protocol of serialization to work, which may not always true in all cases.

  Ultimately, the most effective solution and only in two lines using java class Scanner.

  Tricky is to remember the \A regex that matches the beginning of the entry. It actually indicates Scanner to mark all of the flow, from start to beginning next (illogical).

  publicstaticString convertToString(InputStream in) {    java.util.Scanner s =newjava.util.Scanner(in).useDelimiter("\\A");             returns.hasNext() ? s.next() :""; }

• String conversion number

  Hi all

  I need to convert the string like "-73.28" to the number - 73.28. With decimal string to number Vi I get only - 73,00 output with "-73.28" Dim input As string. What I've done wrong? How to get the required results? Also, note that it must be. the number of output!

  Thank you!

  Hi Nina,

  Firstly: have the decimal separator ',' in a digital indicator is just for aesthetic purposes, you can always calculate using the value...

  (1) you can change the settings of the operating system (Win: settings regional aka regional Einstellungen). I do this for all my computers as it seems "natural" for me when working with scientists/measurement data

  (2) you can move LV to ignore the decimal separator system settings - you will find in the dialog box options...

  But when using properly formatted output functions you do not need to change any setting...

• String to number conversion problem

  I have a VI that pulls in data from a device using VISA, and I got it on another computer to work a few weeks back. I had to transfer the VI to a laptop computer to run a few tests, and now I can't make it work. I am unable to put my VI because the laptop on it's is unable to access the network companies, I will do my best to explain it all, I apologize for the inconvenience! My problem is not however with VISA, it's with an exit VISA number conversion chain.

  I have attached a painting drawing of VI to better explain it.

  I use the block series Visa football match in baud rate and all that many good things to the unit and port settings set of device management. Then, a while loop is entered. The loop will run until you press the stop"" button. The next block of visa is the writing block, he asks for a reading of the device. The next block of visa is the first block of reading, he returns playback in the form of "NA-XXX. X' where x are numbers. The next block of visa is the second reading block, this block just echoes back the command sent to the device. Playback of the first visa read block, "NA-XXX. X' is going exponential/fractional chain to digital converter.

  When you perform a run/debug to highlight run, the release of visa reports the correct value, is the value of the device reading - however the string to number converter generates a 0,000, no matter what channel number is. I am at a loss as to what may be wrong because it's the EXACT set up I had to work very well a few weeks ago!

  I'm using Labview 10 on the laptop, the old computer was labview 7. I'm guessing that this is perhaps the rub... I Redid the VI from scratch, although I have not opened the old VI in labview 10.

  Any help would be appreciated. Again, sorry I am unable to attach the VI.

  Would it not have been easier to just post a screenshot? You might also have used the Tool of Capture of Code. (Which reminds me that I need to install it to my previous versions of LabVIEW, as evidenced by the screenshot I took. )

  As to the question: you probably either:

  • employee analysis of chain initially and when you rewrote the VI you used the regular string conversion functions.
  • Wired an offset value in the string to the number function.

  

• Sub - VI with the entry as a string og number

  At this small Subvi. I wonder if I could make it more flexible and be able to take the string and number as a value ('value dbl' market) entry.  Is there some sort of variable of variant type that could be used?

  It is possible with the key to write OpenG (varying) _ogtk.vi. But the problem is that when you want to read this back, you need to know what type it is. If you write to a different section of the config file each with a specific type, the TI will work. With this solution, you must use the key to reading OpenG (varying) _ogtk.vi to read and convert the value to LV

  Another way is to use Get Type Information.vi of the Variant Data Type palette. The trick here is to convert double or string before saving it in the config file (wire structure dealing with the output type of the vi and do conversions in the case of type dbl and string). Here, too, you must use a different section, one for dbl for string. Here, you use the standard Read button live file configutaion palette.

• How to detect the number of channels on an oscilloscope?

  I have various models sitting around the laboratory, some two-channel, a few four-channel oscilloscope.  I would like for my program to be able to detect the number of channels is available.

  I can just tell my program how much string is available based on the model number, but is there a VISA command to request scope directly what channels he has?  I would also be able to ask what, if any, ability to function math there.

  "all drivers of the oscilloscope must return the instrumentID after initialization, and that should be enough to know the number of channels.

  What Albert was referring to is that all compatible drivers IVI in their base class interface have an attribute/property that indicates how many channels has the scope.

  If you don't want to use the driver of the IVI for the scope then maybe download some of the drivers and check the source code to see how they calculate this dynamic repeated capablity.

• How can I find number of objects in a layer?

  I have a document with hundreds of layers. I want to delete the specific purpose of layers. I iterate through all the layers, but I couldn't iterate over objects within a single layer to find that specific object.

  I there a way I can go through all objects in the layer?

  or

  How can I find number of objects in a layer?

  I'm going through the API documents but could not find.

  Here is the code I wrote,

  var artLayer = undefined;
          if(app.documents.length == 0)
          {
              app.documents.add();
          }
          var myDocument = app.activeDocument;
          var layerCount = myDocument.layers.length;
          
          
          for (var index = layerCount - 1; index >= 0; index-- ) 
          {
              var targetLayer = myDocument.layers[index];
              var layerName = new String( targetLayer.name );
              if(layerName == "Colorways")
              {
                  artLayer = myDocument.layers[index];
                 
                  //Can I iterate through objects in a layer??
  //                for(var newIndex = 0; newIndex < artLayer.items.length;newIndex++)
  //              {
  //                    Need something like this
  //                }
  
  
                  break;
              }
          }
  

  instead of points, you should use "pageItems.

  for (newIndex var = 0; newIndex)< artlayer.items.length;newindex++)="" there="" is="" no="" "items"="">

  for (newIndex var = 0; newIndex)<>

  or as in your second post, instead of the activeDocument, target your layer

  index

  index
