Convert 1D array element to integer

Does anyone know how I can extract the value (element) from a 1D array so that the output value is an integer ? I'm having signal incompatibility problems (again). I need to use the particular element from an array in various math blocks i.e. Add
Solved!

The following is the error message that I'm receiving:
These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required.
The type of the source is 1-D array of
double [64-bit real (~15 digit precision)].
The type of the sink is double [64-bit real (~15 digit precision)].
I'm puzzled why LabVIEW is telling me that the data types do not match when the Source & Sink are the same (double 64-bit real) ?

How do I convert an array of BYTES (where each BYTE represents a bit) into a single Hex number?

I am reading a signal from a USB-8451. This signal is stored as an array where each element represents a bit in the signal, but is stored in the array as a byte. How do I convert this array into a single Hex number. I attatched what I have so far, there are a few extra things to help me see what ia going on. One code uses Queue and the other uses arrays, let me know if you can help.

That makes absolutely no sense. What do you think is happening when you write the digital lines? You're setting a pin high. That voltage is being generated by the 8451x. I think you're not understanding what your mentor is saying. If it's an I2C device then you should be able to use the I2C function to simply talk to it. You still have not indicated what the device is, so there's little more I can say about that aspect of it.
As far as the conversion is concerned, you basically need loop through your array of "bits", taking 16 at time since you said you have 16-bit values. It's not clear from your code whether your eventual goal is to get a numeric value or a string. This does not appear to be a subVI, so a simply numeric indicator formatted to display in hex format should be quite adequate. The array you are generating is an array of rings, whose datatype is I32, but they will have values of 0 or 1. You can use the example just posted, or you can use the attached variation.

How can I convert an array with varying length into a cluster

Hi,
I need to convert an array of n elements into a cluster. Usually, it only involves the "Array to Cluster" function. But since the array length is not constant and the number of elements in the function is constant and can not be changed programaticaly, I need to find another way to do that.
Any ideas?
Thanks.

Hi,
I also tried to do this but without success. I think that's not possible.
For me it's a general problem using labview. I often wanted to generate standard controls dynamically which is not possible (or I haven't found the solution yet). So I think that's the reason why you can't create a cluster during runtime (the program would have to add controls dynamically to the cluster).
Do you have an upper limit for your array-size? Although it needs a lot more memory, it would be a possibility to create the cluster with the maximum number of elements.
If you don't have a maximum, you will have to look for another way, I'm afraid.

Change representation of array elements? (typecast?)

There must be a better way to convert an array of U16 (from an
unflattened picture object I loaded from a BMP file) to a floating
point array than what I've come up with: unwrapping the array,
converting each element, then building a new array! I also tried
array->cluster -> cluster convert U16 ToFloat -> array.
I can't find information on typecast - is this what I want? Where is
the "enum" definition that tells which constant to wire up to "type"?
It's not in the online help, it seems. And I couldn't find any array
conversion VI's that just change the base representation of each
element.
My ultimate goal is to load an image from disk, then display it in
various 3D ways (like a 3D graph, or contou
r, or wireframe, etc) and
apparently need the image data to be a float array to do this.
ANY advice appreciated in advance.
NO SPAM, PLEASE PLEASE!!!

d'oh! Aha! I just wrongheadedly didn't realize that the conversion vi's under
"numeric" could be used on arrays. I was hunting around in the "arrays"
palette. See, I knew there was a better way! Thanks! (Duh)
(and, doesn't the 3D graph need a float array input? Can one change that? the
help on the vi shows it as float array...?)

Problem converting U8 array to date-time string

Hi All,
How can I convert U8 array (time_t data type from C dll) to date time string?
A dll function that I am calling has a structure of string, integer and time_t as one of the parameters. Instead of passing cluster, I pass an array of U8 of the size that the structure should be. All the members of the strcuture and parsed correctly except the date/time.
Function Parameter:
typedef struct {
Int AlarmState ;
Int AlarmGrade ;
TCHAR AlarmMessage [100] ;
time_t AlarmTimeStamp ;
} WV_ALARM_INFO ;
Total size = 4 + 4 + 100 + 4 = 112
Using Call Library Function, I set the parameter type to Array of U8 and size 112.
After the array is populated when the function is called, I have done the following to interpret date and time.
1) Using Extract Zero Terminated String.VI I converted U8 array (of size 4) to string.
2) Type casted string to integer (I32).
3) Swap bytes
4) Swap Words
5) Format Date/Time String.
Please see the attached screenshot for visual display of the above.

Hi Mimansa,
Is it only the year that is incorrect? Also, where did you find that ABC\0 VI that you use 3 times? Did you make it or is it in a labview library somewhere?

How to modify array elements from a separate class?

I am trying to modify array elements in a class which populates these fields by reading in a text file. I have got mutator methods to modify the array elements and they work fine in the same class.
public class Outlet {
     private Outlet[] outlet;
     private String outletName;
     private int phoneNumber;
     private int category;
     private int operatingDays;
static final int DEFAULT = 99;
     public void setPhoneNumber(int newPhoneNumber) {
          phoneNumber = newPhoneNumber;
     public void setCategory(int newCategory) {
          category = newCategory;
     public void setOperatingDays(int newOperatingDays) {
          operatingDays = newOperatingDays;
public static void readFile(Outlet[] outlet) throws FileNotFoundException {
          Scanner inFile = new Scanner(new FileReader("outlets.txt"));
          int rowNo = 0;
          int i = 0;
          String outletValue;
          while (inFile.hasNext() && rowNo < MAXOUTLETS) {
               outlet[rowNo] = new Outlet();
               outletValue = inFile.nextLine();
               outlet[rowNo].setOutletName(outletValue.toUpperCase());
               outlet[rowNo].setPhoneNumber(DEFAULT);
               outlet[rowNo].setCategory(DEFAULT);
               outlet[rowNo].setOperatingDays(DEFAULT);
          inFile.close();
     public static void displayUnassignedOutlets(Outlet[] outlet) {
          int i = 0;
          System.out.println("Showing all unassigned Outlets");
          System.out.println(STARS);
          for (i = 0; i < MAXOUTLETS; i++ ) {
               if (outlet.getCategory() == DEFAULT) {
               System.out.println("\nOutlet Number: " + (i + 1) + "\t" +
                         outlet[i].getOutletName());
Now in the other class that I want to modify the array elements I use the following code but I get an error that "The expression type must be an array but a Class ' Outlet' is resolved".
So how can I modify the array elements? What do I have to instantiate to get the following code to work?

1D Boolean Array to 1D Integer Array conversion for FPGA FIFO

Hello, I am using a PXI7813R card. I would like to pass some data between the target (FPGA) vi and the host vi using the FIFO. I have a FIFO setup to 1023 "32 bit integer" samples. I have a boolean array of 32000 samples which would be the same as 1000 32 bit integers, that I acquired using the PXI7813R card. I would like to convert the 1D boolean array to a 1D "32 bit intger" array. This seems like a more a difficult problem than I first thought as the labview functions are reduced when targetting a FPGA device. I have attached a jpg of how I would like to do it. I am getting a "Arrays must be fixed size in current target" error for the output from the array subset function. I know this is because one of the inputs is not exactly a constant, i.e. the index input for array subset, but regardless of the index, I will only ever be taking 32 bits from the boolean array at any time to convert to a 32 bit integer to then place in the FIFO. Any suggestions of how I may get around this problem would be gratefully recieved. Regards, Michael.

Hi Daniel,
Thanks for your reply.
I had a look at the thread that you suggested and I'm not sure if that would solve the problem I was having, the option box was checked as default. I think my issue has to do with the limitations of the different LV functions when targeting a FPGA device.
I have decided to take another route anyway, it seems that trying to compile a large array (even a 1D boolean array) for a FPGA target both takes a long time and also a lot of FPGA resources.
Thanks again for your reply,
Regards,
Michael.

Convert an array of strings into a single string

Hi
I am having trouble trying to figure out how to convert an array of strings into a single string.
I am taking serial data via serial read in a loop to improve data transfer. This means I am taking the data in chunks and these chunks are being dumped into an array. However I want to combine all elements in the array into a single string (should be easy but I can't seem to make it work).
In addition to this I would also like to then split the string by the comma separator so if any advice could be given on this it would be much appreciated.
Many Thanks
Ashley.

Well, you don't even need to create the intermediary string array, right? This does exactly the same as CCs attachment:
Back to your serial code:
Why don't you built the array at the loop boundary? Same result.
You could even built the string directly as shown here.

Concatenate array elements

Hello ,
I had a string (HEX format 8A6E) which i converted to a boolean array (0,1) . Now I need to further parse this array of (0's and 1's) like taking MSB and bits 12-15 .....but its all in an array.
So to do that currently I can only think of passing it into array subset (results in smaller arrays as needed [0,1,0,1] and then concatening elements [0101] . This concatenated value will then be converted into decimal .
Any help of concatenation of array elemants(numeric) ...or suggestions how to parse such problems better.?

Here's how to convert the 4 MSB to a numeric. (for other bits, you might need to add a mask (logical AND with xF, for example)

Testing array elements

Hello,
This might be a very stupid question, but I did do quite a bit of searching and haven't found the answer. I'm trying to test the value of an array element and not sure how to do this. Here's the code:
public static void Fibbonacci(int end){
     Integer[] f = new Integer[end];
     f[0] = 0;
     f[1] = 1; //2
     int i = 2;
     while(f[i] <= end){
     f[i] = f[i-1] + f[i-2];
     print(f);
     i++;
     print(Array.getInt(f, i));
My understanding is that, as in C, the array elements are pointers (or reference) to the actual values. Is there a way to dereference? How would I assign an element of an array to a single variable to of the same type as the array elements?
Thank you very much for your time!

Hmmmm... it seems I'm missing something. In my previous code,
while(f[i] <= end){doesn't seem to evaluate. also, when I do
j = f;
print(j);
I get 0 even if the element indexed has a non-zero value.

Removing array elements

Hello,
I am working with an array of...let's say...cars which are assigned id #'s starting at one and adding one each time a new car is assigned.
Now I want to remove a car from this array but I dont want to leave that array space empty...I need to shift all other array elements one place to the left, assigning new id#'s and spaces to each.
Ideas?
Thanks.

public static void removeCar()
          int current = 0;
          String au = JOptionPane.showInputDialog("Please enter the model of the car to be removed:");
          String ti = JOptionPane.showInputDialog("Please enter the color of the car to be removed:");
          String year = JOptionPane.showInputDialog("Please enter the year of the car be removed: ");
          int ye = Integer.parseInt(year);
          if (numOfCars == 0)
               JOptionPane.showMessageDialog(null, "The lot is empty!");
          else
               if (! remove(current))
                    carlot[current] = carlot[current - 1];
                    JOptionPane.showMessageDialog(null, "Car successfully removed from the lot.");
               else
                    JOptionPane.showMessageDialog(null, "Car was not found in the lot.");
     }Hmmm...still not doing the trick

Convert javascript array to java array

Is there any way possible to convert javascript array to java array?

if you will try to experiment a javascript array
putting it to a hidden element, it will be converted
to a string (comma delimited). You can get the value
of that element as a string and use StringTokenizer
class to put the values into a java arrayThanks, got it.

How to convert String array into int.

void getSoldSms(Vector vecSoldSms)
     String str[]=new String[vecSoldSms.size()];
     String words[]=new String[str.length]; // String array
          for(int i=0;i< vecSoldSms.size();i++)
               str=(String)vecSoldSms.get(i);
          }               //End for
          for(int i=0;i<str.length;i++)
          words = str[i].split("\\|\\|");
          System.out.println();
          for(int j=0;j<1;j++)
          int count[str.length]=Integer.parseInt(words[i]);
          System.out.print(count[j]*advance_count);
          } // end inner for loop
          }          //End for
     }          //End function getSoldSms
how do i convert words which is a string array into int type. i kno string can be converted into int using interger.parseint. but wat abt string arrays??? plz help me out with the above code.

i did tht its still giving the same errorFor Heaven's sake, what about taking a second to try to understand the code you're copying first? If you really can't fix the error yourself, you have a more serious problem than just convertingStrings to ints.
And if you want { "1", "2", "3" } to be 123:
StringBuffer b = new StringBuffer();
for (int i = 0; i < array.length; i++) {
b.append(array);
int result = Integer.parseIn(b.toString());

Found character data inside an array element while deserializing

Hi Experts,
When I am trying to execute the webservice I am getting the following error
Found character data inside an array element while deserializing

I know XI doesnt support array types thats why I have created my own structure as follows
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="retrieveInventory" type="InvArray" />
<xsd:complexType name="InvArray">
<xsd:sequence>
<xsd:element name="pOutletList" type="xsd:string" maxOccurs="unbounded" form="qualified" />
<xsd:element name="pSkuQuantityList" type="xsd:string" maxOccurs="unbounded" form="qualified" />
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
This webservice takes input like
storenumber1;storenumner2....
item1,qty;item2,qty.
I am passing values like this to my webservice. But still I am getting the same probl

The problem doesn't seem to be related to the XI system. Have you done any configuration at receiver Webservice to convert the string data passed through XI into string array data? I think there is a mismatch in what XI sends and receiver expects.
