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.
Trying to help,
Ben

How to convert 1D array of string to string

How to convert 1D array of string to string.

Maximus00, as Pavel indicated, there is a lesser known feature of "Concatenate Strings" that does exactly what your code is doing if the input is an array of strings. In one step! See attached image.

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;

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 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 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 String array into int.

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());

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.

Converting an array to a list using javascript

There are several methods that return arrays, which we all know express cannot handle. The IDM faq metions you can use a script tag to manipulate array data, but gives no example. I like this method because some methods I encounter preface the object name with the object type, and the data needs to be cleaned before use. I always like little snippits that can be reused, so I'm sharing this one.
Here is how to convert an array to a list, assuming the array is captured in "stupidarray":
    <split>
      <script>
        var myarray = env.get('stupidarray');
        // Code to manipulate the array
        outputarray = myarray.join(",")
        // Other code to manipulate the string before output
        // i.e. Stripping out the object type tags!
        // outputarray.replace(/User:/g,"");
      </script>
      <s>,</s>
    </split>

there is a waveset util class provided for this, please check API

Hi,
How to convert bytes[] into multipage File object?? ]There's no such thing as a "multipage File object." You ought to re-read this thread closely, and read the [API docs for File|http://java.sun.com/javase/6/docs/api/java/io/File.html] to clear up your confusion about what a File object is.
I used the java.io.SequenceInputStream to concatenate two input streams (basically .pdf files) into a single input stream. I need to create a single multipage pdf file using this input stream. Then you need a pdf API, like iText or fop. You can't just concatenate pdf files, word docs, excel sheets, etc., like you can text files. Google for java pdf api.

How can I convert an array off byte ( byte[] ) into an Object using MIDP 2.0 / CLDC 1.1 ?

How can I do this ?
Waiting answers
Rodrigo Kerkhoff

There are no ObjectOutputStream and ObjectInputStream classes in CLDC. You must know what you are writing to and reading from the DataStream. You should write the primitives like int, String to the DataOutputstream at one end and read those in exactly the same sequence at the outher end using readInt(), readUTF() methods.
