Adding a char to an array

Hi
I've got the following code to add a char to an array but I keep getting a runtime error and can't see what i'm doing wrong
int x = 0;
String RowR[] = {"", "", ""};
for (int i=0; i<co_ordinates.length(); i++)
RowR[x] = RowR[x] + co_ordinates.charAt(i);
if (x>2)
x= 0;
else
x = x + 1;
}Thanks

Adding data to a tree array

How to add data from the database to a treenode declared as an array?
for example,adding database data to top[0]...like empno values

Basically I'm doing DES from scratchWoah! Stop right there.
Why do you do that? You know that implementing an encryption system is very hard and very easy to get wrong. Even if it is a well known one.
Do you plan to use this in a production environment or do you simply want to try it to have done it once?
If you plan to use it, then please do yourself a favor and stop it. If you simply want to have it implemented once, then don't let me stop you.
Also: If you really want to go ahead, then you really should learn how to do bit manipulation using the "real" data structures (i.e. BitSet or even int/long depending on performance requirements and amount of data handled).
You can even write your own wrappers with a usefull toString() implementation to keep that "easy-to-check visually" feature.

How to search a char in 2d array any direction

the method will take a string argument and convert them into char and try to find them in a 2d array.
It is more like a word puzzle(wordSearcher).Here's what i've done so far...
public void find(String word)
for(int a = 0; a < word.length(); a++) {
char oneChar = word.charAt(a);
String oneStringchar = String.valueOf(oneChar);
// Searching through in South Direction
for(int i = 0; i < g.length; i++) {
for(int j = 0 ; j < g.length ; j++) {
if (oneChar == g[j]) {
canvas.draw(oneStringchar, (i * WORD_SIZE) + POS_X, (j * WORD_SIZE) + POS_Y);
}

   // Searching through in South Direction
   for(int i = 0; i < g.length; i++) {
      for(int j = 0 ; j < g.length ; j++) {
if (oneChar == g[i][j]) {
canvas.draw(oneStringchar, (i * WORD_SIZE) + POS_X, (j * WORD_SIZE) + POS_Y);

Adding time stamp to table/array

Hi,
In my posted VI I am displaying some collected temperature data on a table. What I am having trouble with is getting the time data to work properly on the table. When I set the include time data to true, it reads out the time as 1904 etc. I'm not sure if it's possible for me to include a time stamp in my array because when I try to convert a time stamp to a double precision float, the output is still a cluster, and thus cannot be added to the array. I've also tried to convert the array to a string and concatenate the time stamp on, but the signals input for the table does not accept strings, and because I would eventually like to export this table to a spreadsheet in a file, I don't really want to link the strings to the indicator directly. I've tried to work with the instrument as well, but when I read time data from it it gives it back in the form of multiple numbers, such as 2008, 8, 28, 13, 30, 31.12 and I can't consolidate it to one number. Needless to say, I'm a little stumped and am open to suggestions on how to fix this problem, whether its a quick fix or a change in the way I'm trying to record the data.
Thanks in advance,
Mike

Automated Thermal Testing Table.vi ‏75 KB

Here are the sub VI's that I'm using. The inner while loop is designed so that the loop will halt immediately when stopped, and not have to finish its current iteration, as the iteration period is intended to be rather long. I may modify the program to have a programmable start/stop time later, but this is at least my temporary solution. The purpose of the decimate array function is to seperate out the channel label from the actual data so they can be placed as headers in the Excel function. The intent was likely not clear with the lack of the SubVI's. Overall, the display table on the front panel is no longer necessary, it was just for me to see how the table was working in the early stages of development.
The one issue I had with your suggestion is the fact that I the build waveform function only accepts a 1-D array for the waveform input, and with multiple and variable number of channels being used I'm not sure how I could easily manipulate the data I gather into multiple 1-d arrays.
As always the help is appreciated,
Mike

Adding next element into an array

I can manage to add the first element as I want in a for loop, however, the next element simple overwrites the index array element. I would like it to add the next element to the next space in the array.
This is how I have declared it.
private String stuff[];
This is it initialised, with 10 as an example.
Stuff = new String[10];
This is inside a method with a string tokenizer ("st").
while(st.hasMoreTokens())
boolean comparsion = enter.equals(st.nextToken());
if(comparison == true)
stuff(i) = st.nextToken(); <<the brackets next to stuff () are meant to be [] but forum formats to italic
I am trying to add values that match what is entered in a parameter (enter is the parameter variable) against the tokens in a file. It seems to add the first match in the array and then if run again it replaces this a new match and is not added as the second element. Any help much appreciated.
Thanks.

Use the code tags as follows next time:
your codeThank you.
Your problem is you do not increment i;
stuff = new String[10];
int i = 0; // declare and initialize i
while (st.hasMoreTokens())
boolean comparsion = enter.equals(st.nextToken());
if (comparison) // no need to == true
stuff[i] = st.nextToken();
i++: // increment i
}

Adding time char to infocube

Hi,
What precautions i need to take to replace a time char with another time chat into a infocube and infocube is in production.
Thanks in advance
krish
Edited by: kris202729 on Dec 19, 2011 3:45 PM

It's depend upon which Time Char. you are adding.
1) I assume that 0CALDAY already in the flow and you are including 0CALMONTH which is mapped to 0CALDAY then there is no impact on production data.
2) If 0CALMONTH already in the flow and you are including 0CALDAY then new data of 0CALDAY will come on date when you are included 0CALDAY production data.

Adding an element in an array of cluster of 2 elements

Hi all,
I have a 1D array containing a cluster of 2 numeric elements (= 2 rows of 100 values).
From this array, collecting new data in for loop, I want to create another array containing a cluster with 9 elements: in each for I want to add an element (= like one row).
After this, I want to compare data from one element with a fixed value, and when the value is find in the element, I want to extract the values of the 8 other elements at this point.
Thanks
Dze

Sorry I didn't understand you well. To use only arrays, you'll need 3D arrays, as you can see in the example attached. I've made two variants, one with your method (don't know if there's an easyer one) and one with the method I think is easyer, after that, you can search in the 3D array easyer that in the array of clusters of arrays (uff...). If I misanderstood you again, please let me know.
Hope this helps

Adding individual cells from 3D array's pages to make one 2D array

Hi everyone,
Am a beginner, and have begun to like Labview. Especially because of great help available online (here) and other videos.
Have managed to use all basic functionalities, but when I tried to add cell(i,j) across all k's (pages) of my 3D array, I am out of wits.
Tried Mathscript, but it doesn't handle 3D arrays. Eventually, Formula Node (C) came to rescue. Logic to do this is a no-brainer, but I don't know how to do it in Labview. Have tried things ranging from For loop, Insert into Array, Replace Array, Shift Register etc.
If someone can answer this, I would be happy to get embarassed.
Thanks

Here's another possibility.

Adding a pre-existing RAID5 array

I'm running a solaris file server. I'm booting solaris off of a single disk and then have a RAID5 array across three disks for my data. I removed the disk that solaris was on, put in an empty hard drive and installed solaris again.
My Question: How can I add my RAID5 array from my previous solaris install while keeping my data?

Ok, so I ran metastat -p on the old install and got
d0 -r c3d0s2 c1d0s2 c4d0s2 -k -i 32b
Meaning that the name is d0, the disks it's on are
c3d0s2 c1d0s2 c4d0s2 with an interlace size of 32b
Assuing my disks are named the same thing on the new
solaris install (they should be) I just feed that
line there to metainit? As long as you have SVM configured on the machine, yes.
Edit Final: Tried metainit, got the following
metainit: pbfs01: there are no existing databasesThen you haven't set it up yet. You need to create metadevice replicas somewhere. They can be on the boot disk somewhere or on the array. It doesn't matter.
The location of the old ones on the other machine would be shown by 'metadb'.
If they were on the array, you can use the same location. When you do that, it will overwrite the old replicas.
Once done, the 'metainit' command will work.

Adding Simulate signal value to array

This is my first VI. I'm passing an array of 5 values which gets concatenated together into a string. I thought it would be neat for the 5th value of the array to always be changing so I'm using the Simulate Signal VI. I have the output from that VI working right but I'm not sure how to replace the 5th element.
Thanks for your help
Solved!

Hi Scott,
I think you're fairly close to getting what you want! After you insert the signal into the array, you should wire the output of the Insert Into Array function into the Array to Spreadsheet String function. Right now it looks like you are just concatenating the array generated by your autoindexed for loop and ignoring the array you inserted the sine wave into.
I hope this helps! Good luck!

OutOfBoundsException with char array

in the catch part how can i delete the last char in the array so it doesnt keep giving me the exception? Thanks for any help.
try
     passWord[counter] = e.getKeyChar();
     counter++;
     System.out.print("*");
catch(ArrayIndexOutOfBoundsException b)
     System.out.println("Your passwords is too long, use back space to go back");
         //need statement to remove last char in the array
}

i'll try it, thanks. But out of curiosity how would
you delete using backspace?If you had to do it, it'd be quite a bit of work:
1) is the input empty? if so ignore
2) remove last char from input field and erase its view
3) position the cursor at the correct position
but lucky for you, you don't have to do that yourself, the JPasswordField
does it all for you ;-)
kind regards,

Char array conversion from String: toCharArray()

Greetings,
Can anyone tell me why this code:
import com.wuw.debug.Trace;
public
class charTest
   public static void
   main( String[] args )
       String strIn = new String( "strIn" );
       Trace.DTRACE( "strIn: "+strIn );
       Trace.DTRACE( "strOut: "+strIn.toCharArray() );
}produces this output:
[DTRACE]: strIn: strIn
[DTRACE]: strOut: [C@1fef6f
and not:
[DTRACE]: strIn: strIn
[DTRACE]: strOut: strIn

Because:
String.toCharArray returns an array of chars.
An array is basically an object in java.
Objects are converted to strings with the method toString - if it's not implemented in your class the string that method returns will be of the form classname@hashcode.
In the case of a char array, the name of the class is "[C". The hashcode of you object seems to be "1fef6f" (in hex).
You'll just have to remember that an array of chars is [i]not a string in java.
