How to convert an array of Integers into String

So how can an array of integers be converted into a string?
As I do not have a javac with me now, I hope you guys could help.
Can it be done this way:
int [] value = new int[] {2,3,4,5,6,7}
String strValue = "";
for (i=0; i<value.length-1; i++)
strValue += value;

Instead of working with Strings, I would suggest you use a StringBuffer. It will improve memory utilization.
Like this:
int [] values = new int[] {2,3,4,5,6,7};
StringBuffer sbTmp = new StringBuffer();
final int size = values.length;
for (i = 0; i < size; i++) {
String intStr = Integer.toString(values);
sbTmp.append(intStr);
String strValues = sbTmp.toString();

How to convert an array collection instance to a complex object for interaction with webservice

Hi there,
I have a stubborn problem that I am trying to work out the best way to solve the problem. I am interacting with a WebService via HTTPService calling a method called find(String name) and this returns me a List of ComplexObjects that contain general string and int params and also lists of other Complex Objects. Now using the code:
ArrayCollection newOriginalResultsArray = new ArrayCollection(event.result as Array)
flex converts my complex objects results to an arraycollection so that I can use it in datagrids etc. Now up until this part is all good. My problem is when getting a single instance from the results list, updating it by moving data around in a new datagrid for example - I want to interact with the webservice again to do an create/update. This is where I am having problems - because these webservice methods require the complex object as a parameter - I am struggling to understand how I can convert the array collection instance back to my complex object without iterating over it and casting it back (maybe this is the only way - but I am hoping not).
I am hoping that there is a simple solution that I am missing and that there is some smart cookie out there that could provide me with an answer - or at least somewhere to start looking. I guess if I have no other alternative - maybe I need to get the people who built the service to change it to accept an array - and let them do the conversion.
Any help would be greatly appreciated.

Hi Bert,
According to my knowledge you can use describeType(Object) method which will return an XML... That XML will contain Properties and values just iterate through the XML and create a new Object..   Probably u can use this method...
public function getObject(reqObj:Object,obj:Object,instanceName:String,name:String=null,index:int=-1):Obj ect
            if(!reqObj)
                reqObj = new Object();
            var classInfo:XML = describeType(obj);
            var className:String = instanceName;
            if(name!=null)
                className=name+"."+className;
            if(index!=-1)
                className=className+"["+index+"]";
            for each (var v:XML in classInfo..accessor)
                var attributeName:String=v.@name;
                var value:* = obj[attributeName]
                var type:String = v.@type;
                if(!value)
                    reqObj[className+"."+attributeName] = value;
                else if(type == "mx.collections::ArrayCollection")
                    for(var i:int=0;i<value.length;i++)
                        var temp:Object=value.getItemAt(i);
                        getReqObject(reqObj,temp,attributeName,className,i);
                else if(type == "String" || type == "Number" || type == "int" || type == "Boolean")
                    reqObj[ className+"."+attributeName] = value;
                else if (type == "Object")
                    for (var p:String in value)
                        reqObj[ className+"."+attributeName+"."+p] = value[p];
                else
                    getReqObject(reqObj,value,attributeName,className);
            return reqObj;

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.
Ideas on why the year is incorrect?

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?
Thanks,

How to convert char array to string

sirs,
i have written a method in java which will return a randomly generated string of a fixed length. i am creating one one character and inserting it into char array.
at last i am converting it to string
like this
String newpass= pass.toString();// pass is a char array
but problem is that the string is having different value what i hav generated.
if i am doing like this..
String newpass= new String(pass);// pass is a char array
here newpass is having correct value but having some error
error in the sense when i print
System.out.println(newpass+"some text");
"some text" is not printing
can you suggest the better way

/*this is my method */
private String generateString(int len){
          char pass[] = new char[10];
          int cnt=0;
          int temp=0;
          Random randomGenerator = new Random();
               for (int idx = 0; idx < 1000; ++idx)
                    temp = randomGenerator.nextInt(1000)%128;
               if((temp>=65 && temp<=90)||(temp>=97 && temp<=122)||(temp>=48 && temp<=57))
                         pass[cnt]=(char)temp;
                         cnt++;
                    if(cnt>=len) break;
               String newpass= pass.toString();
               String newpass1= new String(pass);
               System.out.println("passed pass"+newpass+"as"+newpass1+"sa");
          return newpass;
here newpass and newpass1 are having separate values
why ??

How to convert digital array data into analog signal

i want help to convert digital data array into analog signal

shubham62 wrote:
We are implimenting real time audio trans-receiver. We have converted input audio data(analog form) into digital data. At the receiver side we received digital data which is in the form of digital data array.But we are unable to recover back our original input data. So please help us to sort out the problem.
Still no useful information. How was the data converted to digital in the first place? What conversion parameters did you use? As was said, you just need to do the math backwards to get it back into the analog.

How to convert an array of bits into an array of bytes?

If I have an array of 1s and 0s, how can I pack them
into an array of bytes (8 bits)?
Thanks.

NI recommends to get rid of 4.x mode (Quote from the help file: "National Instruments recommends reworking any application that uses the Convert 4.x Data mode as a long term solution."). For this reason, I have attached an alternative example to give you some ideas.
(The previous example (using 4.x type cast) is actually slightly flawed, because for some reason it only produces even sized output arrays (why???) so you would need to trim the resulting array as a function of the input array size.)

How to convert an array having ramp pattern to ..................

i used an ramp generator to obtain numbers. the output is an array
having ramp pattern. how do i convert it to a set of numbers?
thank you,
siva.

Hi Siva,
Take a look at the example that can be found at
Help >>> Search Examples >>> Browse >>>Hardware Input and Output >>> DAQ >>> Analog Output >>> Continuous Generation.VI.
You are not going to be able to get better than 1KHz out of your digital output line becuase Windows was never designed to be able to let you cycle that fast. It was designed to to 30Hz, just fast enough to make it look like it is smooth.
The example I cited should let you "crank-up" your output speed. You will probably have to modify it to get a square wave but, that is just data.

How to convert a VISA Resource Name to String?

I would like to convert a VISA Resource Name (invalid reference) to string so I can open a session to a GPIB instrument.

You can typcast the VISA Resource Name, but I usually just treat it like a string. You can connect it directly to string indicators or to any VI that takes a string input. You can even search, concatenate and split it like a string. You can also feed strings into the VISA Resource Name inputs of the VISA functions.

How to convert digital signal to hexadecimal string?

Hi!
My problem seemed to be very easy but I cannot find a simple solution. Namely, I have to make a simple project that acquires bits from a single digital line (not that it is important but I use one channel of a PXI 6552) and stores a certain number of bits (let’s say 1000 bits) from the channel in a txt file in hexadecimal format. I can convert it to a binary array of unsigned integers and make a loop that reads every 4 bits and calculate hexadecimal value but is it possible that there is no simpler way?!
Thank you!
Solved!
Go to Solution.

Thank you for your prompt reply! I understand that hexadecimal is just a format of presenting data but I have a problem to write digital data in that format to a txt file.
To make it easier for understanding and for testing purposes as well, I have made a test program that reads hexadecimal values from a txt file (the structure of this file is the structure I need to get at the end), transforms it in a digital stream as I get from the pxi 6552 (I had to change a bit the VI DTbl Binary U8 to Digital Stream.vi), and write it back to a txt file. This test program still needs some fixing to make input and output file exactly the same, but for the start output file is a txt file with hexadecimal values of my digital stream. I was wondering if there is a simpler solution for the while loop in this example.
I hope this example made it clearer a bit.
