¿How to fill an array with random letters?

Hello, I was wondering If filling a bidimensional array
(8x10 for example) with random letters could be done in C#, I've tried tons of stuff, but I can't manage to do it. Thanks in advance.

Yes.

With exactly which part of this assignment are you having trouble?
Can you create a 2-dim array of characters?
Can you generate a random letter?
Show the code you have written so far.
Don't expect others to write a complete solution for you.
Don't expect others to guess as to which part you're having difficulty with.
Show the code you have working, and the code which you have tried which isn't working,
Explain what is happening with it which shouldn't.

How to fill an array with random numbers

Can anybody tell me how I can fill an array with thousand random numbers between 0 and 10000?

import java.util.Random;
class random
     static int[] bull(int size) {
          int[] numbers = new int[size];
          Random select = new Random();
          for(int i=0;i<numbers.length;i++) {
harris:
for(;;) {
int trelos=select.nextInt(10000);
numbers=trelos;
                    for(int j=0;j<i;j++) {
if(trelos==numbers[j])
continue harris;
numbers[i]=trelos;
break;
return numbers;
/*This method fills an array with numbers and there is no possibility two numbers to be the
     same*/
/*The following method is a simpler method,but it is possible two numbers to be the same*/
static int[] bull2(int size) {
     int[] numbers = new int[size];
Random select = new Random();
for(int i=0;i<numbers.length;i++)
          numbers[i]=select.nextInt(9);
          return numbers;
     public static void main(String[] args) {
int[] nikos = random.bull(10);
int[] nikos2 = random.bull2(10);
for(int i=0;i<nikos.length;i++)
System.out.println(nikos[i]);
for(int i=0;i<nikos2.length;i++)
System.out.println(nikos2[i]);

How to populate an array with random text files.

I am making a Jeopardy program. I have my program set up so that it retrieves 5 random text files. I just want to know how I populate one array with all the lines from the text files my program is retrieving.

You can read a textfile line by line and add each line to an ArrayList. An ArrayList is very much like an array only that it's "open ended". You can start adding lines without first knowing how many you're going to get. If you still want an ordinary "static" array when you're finished reading lines you can easily get one from the ArrayList and then drop the ArrayList.

How to fill array with random number?

I need to fill a 3-dimensional array that has user-controlled dimension sizes with random numbers (1-10). I'm unsure of how to do this. I feel like I have to use the initialize array and maybe the build array functions somehow but I'm not entirely sure. Any help would be appreciated. Thanks.

Something like this
Kudos are always welcome if you got solution to some extent.

How to build a array with high sampling rates 1K

Hi All:
Now I am trying to develop a project with CRio.
But I am not sure how to build a array with high sampling rates signal, like >1K. (Sigle-point data)
Before, I would like to use "Build Arrary" and "Shift Register" to build a arrary, but I found it is not working for high sampling rates.
Is there anyother good way to build a data arrary for high sampling rates??
Thanks

Can't give a sample of the FPGA right now but here is a sample bit of RT code I recently used. I am acquiring data at 51,200 samples every second. I put the data in a FIFO on the FPGA side, then I read from that FIFO on the RT side and insert the data into a pre-initialized array using "Replace Array subset" NOT "Insert into array". I keep a count of the data I have read/inserted, and once I am at 51,200 samples, I know I have 1 full second of data. At this point, I add it to a queue which sends it to another loop to be processed. Also, I don't use the new index terminal in my subVI because I know I am always adding 6400 elements so I can just multiply my counter by 6400, but if you use the method described further down below , you will want to use the "new index" to return a value because you may not always read the same number of elements using that method.
The reason I use a timeout of 0 and a wait until next ms multiple is because if you use a timeout wired to the FIFO read node, it spins a loop in the background that polls for data, which rails your processor. Depending on what type of acquisition you are doing, you can also use the method of reading 0 elements, then using the "elements remaining" variable, to wire up another node as is shown below. This was not an option for me because of my programs architecture and needing chunks of 1 second data. Had I used this method it would have overcomplicated things if I read more elements then I had available in my 51,200 buffer.
Let me knwo if you have more qeustions

How to fill combo box with list of all SQL server

Ok, I know how to find all SQL servers that I need, I have code for that task, and I have Array of all servers.
My problem is ...
I made setup project and do a huge work, and in the end this task appear!
I used ORCA tool to change TextBox (A) template in visual studio (2008 by the way), and I transform first TextBox to ComboBox.
Now, the little part that I'am missing is how to fill this combo box with a result of my function for listin SQL servers?
Can I somehow send combobox object to myMethod:
private void FillCombo(ComboBox cmb)
// do the job
or
instanceOfThisCombo.Items.Add(listOfSQLServers);
please help me to solve this... thanksc#

Hi Valerij,
The ComboBox control in an MSI dialog uses the ComboBox table to populate the items in it. To get what you want, you need to update the ComboBox table in the MSI package with your application and run the MSI package. The following KB article describes how to dynamically populate a ListBox control in Windows Installer:
http://support.microsoft.com/kb/291329
This method introduced in the above KB article also applies to populating a ComboBox control in Windows Installer.
I don't think it's possible to run the application as a Custom Action from within the MSI package because the application will modify the content of the MSI package which is currently running. So you need to launch the MSI package from within your application after updating the ComboBox table. In short, when installing, just run your application which updates the ComboBox table and install the MSI package.
Hope this helps.
If you have any question, please feel free to let me know.
Sincerely,
Linda Liu

How to fill internal table with no data in debugging mode

Hi all,
I modified one existing program.Now I want to test it.I am not given test data.So in the middle of my debugging, I found that one internal table with no data.My problem is how to fill that internal table with few records in that debugging mode just as we change contents in debugging mode.If I want to proceed further means that internal table must have some records.
Please I dont know how to create test data so I am trying to create values temporarily in debugging mode only.
Thanks,
Balaji

Hi,
In the debugging do the following..
Click the Table button..
Double click on the internal table name..
Then in the bottom of the screen you will get the buttons like CHANGE, INSERT, APPEND, DELETE..
Use the APPEND button to insert records to the internal table..
Thanks,

In sm30, when save, how to fill the table with the system data in the table

Hi all, in SM30, we have user name and time fields, when we create record, after we click the SAVE button, it will automatically fill the fields with the system data, how can we realize it?

Hi ,
Do like this.
1. Go to SE11 -> give your table name and press on change button .
2.Go to Menu->Utilities-> Table Maintainance Generator , then it will take you another screen .
3.Assign Functin group if already have one , other wise create function group and assign
4.Go to Menu->Environment->Modification->Events , again it will take you to another screen
5.Click on new entries
->Now press F4 in T column . Select<u> "01" - Before saving the data in the database</u> and in form routinue give any name of the routinue like "SAVE_USER_DATA" and press enter then u can see an editor symbol in next column click on that it will take you ABAP editor there type this code .

check and activate the code .
With this your job will be complete . Now while entering data just leave columns blank , they will insert corresponding username and time

How to build a array with collected data

Hi,
I have collected data from serial port with VISA. Now I want to build a array with 100 date points. Should I connect VISA Read with Build Array directly? How to do it?
PS: All of them are in a While Structure.
Thank you!

An inefficient way to create the array is to use the build array and a shift register as shown below. It's more effecient in terms of memory management to create the array and then use the replace array subset as shown in the other image. Of course, if you don't need the array inside the loop, just wire the value out of the while loop and on the exit tunnel, right click and select 'Enable Indexing'.

How to create a array with variables dimensions?

I try to create a array like that:
Object[][] data;
data = new Object[] [];
But that's doesn't work!
Apparently I must specify the dimension of my array
So I have done like that :
Object[][] data;
data = new Object[3] [3];
And that work!
But the problem is when I need to add extra elements to my array.
If I write :
data[4][1] = "123";
I have the error message :
java.lang.ArrayIndexOutOfBoundsException
So, how can I defined a array with variables dimensions OR how can I add a dimension to a array?

if you have:
Object[][] data;
data = new Object[3] [3];you end yo getting ArrayIndexOutOfBoundException if you try to point to some other Indexes. You can increase the size by doing new:
Object[][] data;
data = new Object[4] [3];and then copy the old Arrays to this one... this is heavy.
Other thing to consider then is using some other datastructure, such as Vector, which grows along you add elements to it.

How to traverse an array with a for-loop in this certain way...

so I need to traverse an array starting from the first element, then from the last element, then the second element, then the second last element, then third element and so on... in a for loop
how would that look in code?
Any help would be appreciated, thanks!

Wow, that's a really clever and elegant way to do it promethuzz. I actually came up with something already before I read your post so yeah don't worry about me copying or anything. Mine is not as elegant/efficient and I definitely like yours a lot more but I will just share it anyway...it looks pretty similar to the second algorithm The_Matrix has provided. I figured this out from thinking how quicksort compares its pivot with the two indexes...
    int front=0;
    int back = a.length - 1;
    int counter =0;
    boolean switchflag = true;
    while(front<=back)
      System.out.println(a[counter]);
      if(switchflag)
        counter = back;
        front++;
        switchflag = false;
      else
        counter = front;
        back--;
        switchflag = true;
    } Anyways, thanks a lot for you guys help, promethuzz, The_Matrix, and newark.
