How to read in text string pairs from an external txt file?

I have an external txt file containing 26000 pairs of strings in the format
string1a   string1b
string2a   string2b
string26000a string26000b
all strings are always 4 characters in length. For example,
a123   jkdh
b456   uusp
How can use TestStand 2013 to input this data into local string array varaibles? I also have legacy testers running TestStand 3.5, so I need a TestStand 3.5 solution as well. Thanks in advance for any ideas. Hopefully this can be done in TestStand without the use of LabView or LabWindows/CVI.

Daniel E., thanks for the reply.
     It is very frustrating to have to implement workarounds in order to access text in an external file when using TestStand. TestStand already reads in text ini files, so it would probably take a TestStand software developer all of 1/2 day to write the code and 1/2 day to debug it. Here I will restate the obvious. Engineers have to deal with data, sometimes data generated from other applications. Sharing data in a text file is one of the most basic functions (and one of the easiest to implement). When I think of all the effort needed to support ActiveX, but NI did not see it fit to give TestStand users simple text file read/write functionality, it does not make sense to me. Maybe it was too simple or mundane a task so it did not get developed? Whatever the reason, I think users of TestStand deserve this basic functionality.
     Even if TestStand cannot read the data directly into array variables, it should provide some mechanism to read the text from the file, either line by line or all file text into a string, so the data could then be parsed into the array variables I need.
     I will pursue a CVI or LabView solution. Please also know that I am not directing these comments at you, I do appreciate your reply.

Calling a variable from a external txt file that is equal button name

It is then up to you to split that string up (search for split string on this forum for methods) into it's individual components.
If the text file contains a standard structure on each line, i.e. it is a fixed delimited structure, then you could use external tables to read the data instead.

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

How do I get text to flow from one page to the next in Pages 5?

How do I get text to flow from one page to the next in Pages 5 with the Maverick system?

What may be overlooked in Pages v5 is the notion of combining Text Boxes via the Menu > View > Show Arrange Tools. When you select two Text Boxes, an extra panel unfolds at the bottom of the Arrange Tools window. Uncheck one Text Box and this panel abruptly disappears.
One can achieve text flow effects between Text Boxes differently based on how one positions the Text Box overlap, and choice of effect above. Though not the accustomed flow found in Pages ’09 v4.3, flow does occur. Consider the possibilities of combining a Shape and a Text box to cut an irregular Text box.
If I create two Text Boxes and position them side by side with outline touching and choose Unite, this creates one larger Text Box and text flows across and down. On the otherhand, if I overlap the upper left corner of a lower Text Box over one above and to the left, then choose Union, pasted text fills the first Text Box and then flows across and down into the other box. Here is a Union example:
Intersect will leave a small Text Box where the two overlap, so not much value there. Subtract will cut a chunk out of one Text Box that is the size of the overlapping piece of the second Text Box:
And Intersect will leave an island in the center where the two Text Box overlap, with flow jumping over this bridge.
Clearly, this is not what we were accustomed to in the past, but with imagination, style, and layout tuning, it does offer alternative Text Box creativity and layout. Of course, there is the option of simply returning to the previous Pages version for true Text Box linking that most will want to use.

How to Read the "text file and csv file" through powershell Scripts

Hi All
i need to add a multiple users in a particular Group through powershell Script how to read the text and CSV files in powershell
am completly new to Powershell scripts any one pls respond ASAP.with step by step process pls
Regards:
Rajeshreddy.k

Hi Rajeshreddy.k,
To add multiple users to one group, I wouldn't use a .csv file since the only value you need from a list is the users to be added.
To start create a list of users that should be added to the group, import this list in a variable called $users, the group distinguishedName in a variable called $Group and simply call the ActiveDirectory cmdlet Add-GroupMember.
$Users = Get-Content -Path 'C:\ListOfUsernames.txt'
$Group = 'CN=MyGroup,OU=MyOrg,DC=domain,DC=lcl'
Add-ADGroupMember -Identity $Group -Members $Users

How to prevent a text in script from displaying if its value is zero

How to prevent a text in script from displaying if its value is zero

Hello Nagaraju,
                       What you were doing is partially right.
The correct format to write in the script is as follows :
/: if &PRICE& ne 0.
&PRICE&
/: endif.
This should work. Let me know how it goes.

How to read a text/html file in java regardless of its encoding?

Hi All,
How to read a text/html file in java regardless of its encoding?
1. Is there any way to identify that a file (read using FileInputStream/or any other means with java.io package) has been saved with which type of encoding i.e. whether the file is using ANSI encoding or Unicode encoding or other?
2. Is there any standard way to read an encoded file (i.e. files having UTF-16 format for Asian locales character support) and un-encoded file (i.e. files having ordinary ANSI format) correctly without knowing the user input?
The problem is that while creating an instance of 'InputStreamReader' (ISR) we can pass the encoding type used (otherwise it takes the system's default encoding type), and the ISR expects the file to be in the same encoding format otherwise it reads it as some junk. But we don't know which file the user is going to pass whether it is Unicode (for Asian locales file should be in Unicode) with or ANSI coded (for non-Asian / English locales user generally uses ANSI encoding).
Regards,
Sam

1. There is no reliable way of guessing the encoding of a file without that information. Thats why XML for example has very strict rules wrt. it's encoding (short form: use UTF-8 or UTF-16, if you use anything else, you'll have to specify it)
2. you might be able to make an educated guess if the possible range of encodings is limited, but it will probably never be 100% certain
3. The HTML file might have a header entry "<meta http-equiv..." that tells you about it's encoding. You could try to read the start of the file and see if you find that, then if you found it re-read the entire file.

How to read a text file through pl/sql

pl/sql runs inside the database. so your file also should be on the database server file system for you to be able to read.
check out UTL_FILE package. This is the database package to read/write files on the database server.

How can I transfer text and format from a Word Doc to a new Pages Doc?

How can I transfer text and format from a Word Doc to a new Pages Doc?

Select, and Copy in the Word doc and Paste in the Pages doc. It may not be perfect. Importing (Opening) the Word doc is probably better than using Copy/Paste for large amounts of content.
