Identifying text file names and importing on single Excel sheet

Hey!
Does anybody can help me with Excel VBA macro code in order to import data from text files into single Excel spread sheet? I want to create User Form where user can select start and end date of interest and macro code will import
bunch of text files depending on user demands...
My text files are named: 20130619004948DataLog.txt (meaning: yyyy mm dd hh mm ss). Text file contains recordings for each 15 seconds... It would be great to omit time tail (meaning that user can only specify date). Text files for one day of interest (I have
text files covering whole year):
20130619004948DataLog.txt
20130619014948DataLog.txt
20130619024948DataLog.txt

- Make a new Excel file
- Open the VBA editor
- Add a Userform
- Place 2 text boxes and 1 command button on that form
- Paste all code below into the code module of the form
- Download this file:
https://dl.dropboxusercontent.com/u/35239054/FileSearch.cls
- In the VBA editor press CTRL-M and import that file
- Save the Excel file in the directory that contain your text files
- Run the form
You can format the columns of the sheet as you like, e.g. column E:H should be a number with 5 decimal places. The top row can contain some headings. My code did not affect the formatting or the headings.

Find word in text file and count specific words

now I'll try to explain what I need to do. I have file.txt file, It looks like:
John //first line - name
One
Three
Four
Peter //first line - name
Two
Three
Elisa //first line - name
One
Three
Albert //first line - name
One
Three
Four
Nicole //first line - name
Two
FourSo I have program's code:
public class Testing {
        public static void main(String args[]) throws Exception {
            Scanner input = new Scanner(System.in);
            System.out.println("Select word from list:");
            System.out.println();
            try {
                FileReader fr = new FileReader("src/lt/kvk/i3_2/test/List.txt"); // this is list of words, everything all right here
                BufferedReader br = new BufferedReader(fr);

                    System.out.println(s);
                fr.close();
                String stilius = input.nextLine();   // eneter word which I want to count in File.txt
                BufferedReader bf = new BufferedReader(new FileReader("src/lt/kvk/i3_2/test/File.txt")); // from this file I need to count word which I entered before
                int counter = 0;

                System.out.println("Looking for information");
                while (( line = bf.readLine()) != null){
                    int indexfound = line.indexOf(stilius);
                    if (indexfound > -1) {
                         counter++;
                if (counter > 0) {
                    System.out.println("Word are repeated "+ counter + "times");}
                    else {

                bf.close();
            catch (IOException e) {
                System.out.println("Error:" + e.toString());
        }This program counting specific word (entered by keyboard) in file.txt.
I need to make this program: for ex.: if I enter word: One It must show:
Word One repeated 3 times by John, Elisa, AlbertAll what I need to elect by who this word repeated. But I don't know really how to make It, maybe LinkedList or I dont know, someone could help me?
Thank you very much.

or I dont know, someone could help me?You need to introduce a variable to store the actual name which must be resetted if an empty line is found and then gets assigned the verry next word in the file.

Finding strings in a text file?

Hi! i'm learning to read text files. what i want to do with this program is to find word 1-3, 2-4, 3-5... and write them in a system.out.println. i found a program that opens files and count words, lines and characters and tried to adjust it do find three-word strings.
i can compilate (hope that word exists) but when i run it, it says: Exception in thread "main" java.lang.NoSuchMethodError: main
anyone who knows what this could depend on?

Thanx in advance!

this may be a stupid question but i'll give it a
shot. ...do i replace my private static void with
public static void or do a add the public?Whether you replace one of your methods or create a new one is up to you, but you have to have a method with this exact signature:
public static void main(String[] foo) {
}(The variable name can be different of course)

Hi...There..
I h'va wrirtten Search application which search words from Simple text files.

pl. suggest me effective method to search word from file so i can make it rapid search.
Actually i 've to provide search on "TEXT VALUE CHANGED EVENT" so even if my process takes more then one seconds it is not physible for me.

Find Change through external text file

Hello folks
I am bit pretty in InDesign scripting so could you please look into this.
How can i change any particular text field in Indesign CS3 document from text file.
I do have find change script but for each InDesign document specific text file is assigned.
So each time i have to modify find change GREP property that is also repetetive of work. Is there any way to get find change information should be extract from external text file.
Many Tanks in advance

In the FindChangeByList script, you could customize the function myFindFile(myFilePath) {...} as to search the FindChangeList text file in the document location rather than the script location. That's an example. The question is: given a document, where will you have the corresponding FindChangeList?

How to find largest number from text file

I am using the "Read from text file" block to read the data from my .txt file into labview. It is now in string format. I have many numbers in the file.
For example:
0.45
0.35
0.12
1.354
1.56
2.89
5.89
0.56
That is what a text file might look like. I want to find which of these numbers is largest, and do calculations with that number. I am having trouble with strings/number formats/arrays, etc. Thanks
Solved!
Go to Solution.

The spreadsheet functions and VIs typically work on strings representing numbers separated by delimiters. This is a typical way to save a "spreadsheet" (of numbers) to a text file, for example .csv files. These are quite versatile and powerful functions. Spend a bit of time becoming familiar with them because you may find yourself using them a lot.

Read a non english word from text file

While Reading thai charater from text file which was sent by QAD(a different application),
We are reading 60 char using substr() function.
If the data is English word it reads correctly with 60 char.
But if it is in thai characters it returns more than 60 char.
In oracle all NLS Char set has been already set.
Can anyone help in this issue
thanks in advance

Maybe you should use SUBSTRC, SUBSTR2 or SUBSTR4 depending on the character set of your database. See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96540/functions119a.htm#87068

Reading first word from text file

Hello all,
I created a program which I can type in a line and store it into a file. What I need my next program to do is read and display just the first word from each line on the text file.
Here is what I have:
import java.io.*;
public class ReadFromFile
public static void main (String args[])
     FileInputStream firstWord;
          try
              // Open an input stream
              firstWord = new FileInputStream ("FileofWords.txt");
              // Read a line of text
              System.out.println( new DataInputStream(firstWord).readLine() );
              // Close our input stream
              firstWord.close();
               System.err.println ("Unable to read from file");
               System.exit(-1);
}

what i would like is my program to get the first word of every line and put it in my array.
This is what i have attempted.

First of all, when posting code, put it between two tags.
Second of all, the pipe is a special character in regex, so you need to escape it as
.split("\ \|");
Erh. So 2 backslashes before the pipe character. Stupid forum won't post it.

When I import a text file(comma separated )into a numbers spread sheet all the data goes into one column. Why does the text not go into separate columns based on the commas.

When I import a text file(comma separated) into a numbers spreadsheet all the data goes into one column instead of individual columns based on the comma separators. Excel allows you to do this during the import.. Is there a way to accomplish this in numbers without opening it in Excel and the importing into Numbers.

Your user info says iPad. This is the OS X Numbers forum. Assuming you are using OS X… Be sure the file is named with a .csv suffix.
(I don't have an iPad, so I don't know the iOS answer.)

Find line number in text file

Hi all,
I need to find the line numbers on a file where a particular string matches.
for example:
A lazy cat
A strong cat and it is black
Black is not good
So I will match for the word black and it will give the numbers say line 2 and 3 it found the match.
I am using the code:
try{
    // Open the file that is the first
    // command line parameter
      FileInputStream fstream = new FileInputStream("c:\\test.log");
    // Get the object of DataInputStream
      DataInputStream in = new DataInputStream(fstream);
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      String strLine;
     String[] arr= null;
    //Read File Line By Line
   String regex = "black";
   while ((strLine = br.readLine()) != null)   {
    // Split the sentence into strings based on space
       arr = strLine.split("\\s");
   if (arr[0].equalsIgnoreCase("black"))
      System.out.print("match found");
    Pattern p = Pattern.compile(regex);
    Matcher m = p.matcher(strLine);Thanks in advance.

Browser can't find a text file opened via the save as dialogue box

Hi there,
I have a servlet which outputs a file using the servlet output stream, with the following lines set:
response.setContentType("application/msword");
response.setHeader("Content-Disposition", "attachement; filename="+ fileName);
servletOutStream.write(myBytes);
servletOutStream.flush();
It works fine for .doc files and it seems the mechanism is that it is saved to the Temporary Internet Folder and delivered from there when the user clicks on the 'open' or 'save' option in the browser popup dialogue box. However... when I try this with text files, (setting the content type to "text/plain") I get the open/save dialogue box up correctly but if I try to open the file it says it cannot find the file, and gives the path under the Temporary Interenet Folder. If I look in there the text file isn't present - though the .doc files are.
So... it looks as if the problem is that for some reason it doesn't save the text files correctly to the Temporary Internet Folder.
I can't deliver the text files inline as a solution as the filename is lost and it thinks it's an html file (which the client doesn't want).
Any ideas?
Alison

At least also set the content length. Your browser may be configured be the default application to open textfiles. If the contentlength is not set, then most applications would refuse to open the file without choosing for 'Save' first and manually open it.

Read words from a text file into an undefined array

Dear all,
Does anyone know how to read words in text file, seperated by all types of spaces ("_", "\n", "\t","\r","\f") and put them into a string array to be used later?
So far I can read the words using the Tokenizer but can't assign to array:
public class reader
StringTokenizer tokenizer = new StringTokenizer(input);
String[ ] array= null; //unknown size of array
int i=0;
               while(tokenizer.hasMoreTokens())
                         array[i] = tokenizer.nextToken();
                         i++;
Any suggestions welcome!
thanks in advance!

Hi
sorry wrote in a hurry ;) din c the problem clearly
there are two approaches
1) best approach for your problem is Vector or ArrayList, these would make life easy for you.
Always collections are better approach over arrays when the size is dynamic. However in your case the size cant be said to be DYNAMIC. coz the number of words will not grow / shrink during the runtime.. i know that number of words are not fixed but dynamic is something which will grow/shrink during runtime. but still collection is better approach.
2)dirty approach
use double dimensional array
String arr[][] = null;
then use one tokenizer for StringTokenizer(str,"\n");
using countTokens on this will give you number of lines.
use this to initialize array
arr = new String[lineCount][];
then iterate from 1 to lineCount and use 1 more tokenizer to get number of words for that line. use this number to initialize the column size for arr[i] like
arr[i] = new String[wordCount];
then store the token using nested for loops in this array
go for the 1st one ;) 2nd one is hedious n time consuming but both will work ;)
cheers
