I was wondering if it is possible to use the code saved in the .txt file using the application.savetotext and save the code in a table, then use the application.loadfromtext to to build the object from a string rather that a .txt file
Does that make any sense? Basically I'm wanting to store all the object codes in a table on separate rows and allow users to select the relevant row and build the object without having to import the .txt file
Yes and no. You would have to write the field content to a (temp) file, then use LoadFromText to read in the object.
But it doesn't make much sense, and I think you are on a wrong track. You could just as well have the objects ready-made in application.

I am trying to create a unique id and attach it to a LabVIEW file so that later I can read back that id and know I am looking at exactly the same file. I must be able to generate the id and read it back programmatically. The information must be hidden from the user accessing the file and persist across operating systems and storage mediums.
I was thinking of just adding it into the file 'comment' section, but it appears the Windows no longer supports file comments.
Any ideas?
I would suggest using the Set Tag method on the VI (with persistence) and saving multiple copies of the VI using the Save Instrument method, where each copy would then have its own unique value of the tag. Note that the method is defined as a scripting method, so you would probably need to enable scripting in the LV options to access it.
I don't think there's any API for enumerating tags, so there would be no way to find the value unless you know what the tag is called. Obviously, it's encoded somewhere in the VI file itself, and presumably it would be possible to extract a list of tags if you know the structure of the file, but that's not knowledge I would expect most students to have.
I'm not sure if you can call the set tag method from Python using an external connection to VI server, but certainly the LV code for this should be pretty simple - basically a for loop with ID generation, a couple of method calls and saving a CSV file so you can keep track of which ID belongs to which student. If you use existing IDs, you don't even need to generate and save the IDs.
So, there is this website where I have to log in and insert values in the add content->person roles and I have to take values from an excel file. I tried entering the values in the database directly but got nowhere. The database is too randomly generated.
I want to know- how to go by this problem? I think python would be the best way but I am more comfortable with java. The images bellow will help understand the situation better-

Try using feeds module:
https://www.drupal.org/project/feeds
Install it on you site first of course. Or look for some similar import module. Maybe this one:
https://www.drupal.org/project/datasources
If nothing succeeds then try making import script on your own. You have to parse document (would be much easier to open it from excel and export as CSV if possible http://php.net/manual/en/function.fgetcsv.php) and have some loop to write content into Drupal system. Use Drupal's functions for that, do not directly write to database. It's not hard as it looks like:

Having a bit of trouble with a script I am trying to create. Basically I would like it to send out a reminder email to send hours I worked that day, then I send a reply, the script will read the email for date start time and end time and then input this data into a CSV/Excel/LibreOffic calc file. A new line for each date. I have manage to sort out the email sending and reading part, then inputting the data into a variable for the next subroutine to read (the excel bit). But I am not sure on how to go about this part. I have seen many suggestions of using Text::CSV and other modules but i'm not certain on how to use them? also how would I go about making it append to the end of the document instead of just overwriting it?
Thanks in advance guys
CSV is very easy to read and parse, and Text::CSV is very easy to use too. What specific problems are you having with Text::CSV, and what have you tried?
If you want true Excel format, it looks like you'd need to read the existing contents with something like Spreadsheet::XLSX, write it back out using something like Excel::Writer::XLSX, and append your data to it as you're back out the original data.
CSV is simpler, though, if you can live with it. You could open the file in append mode, and just write to it. To do so, build up your data into columns, and "combine" them ($csv->combine (#columns)), then create a string out of that ($csv->string()) that you can write to your original file.
I'm creating an excel-sheets that reads the tags from the MP3-files situated in a folder. Yet the time apparently is or calculated from data inside the MetaProperties of a file or is inside those data. When I use the Property MetaProperties VBA always provokes an error, even in using a copy of the example in adapting the appropiate data. Thanx in advance for your solution.
Does this help?

You didn't say what metadata you want, but this method offers a lot of information.
MP3's do not use MetaProperties at all. They actually use the last 256 bytes of the file to store album, track, etc information (the ID3 tag).
See here http://id3.org/id3v2.4.0-structure for more information.
Could some one give an idea about how to convert an excel file into a CLOB in oracle through JDBC. I would like to know how to covert excel file into a String using API available as part of JDK and the conversion from string to clob should be straight forward. Thanks in advance. If a similar question was already raised, kindly provide me the link.
You will need a library out side of the standard java api to read a binary excel document.
You could use the JExcelApi to read in the Excel document then create a CSV String as you read in the document.
If you don't want to use an outside library then I would change the field type to blob and use the setBlob method of java.sql.PreparedStatment passing it a FileInputStream.
When you need to parse the data (read the contents) you can use a library like Apache POI
If you want to use the only standard API, then save the excel as CSV file and process the file as a comma seperated value list. That can easily be done with readline to read each line and split that line to values using the split method on a String.
If you do not need to parse data you should stream the data directly from file to a CLOB and not first transform the excel to a String
An example can be found here: http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/LOBSample/LOBSample.java.html
What is the representation of a spreadsheet in text format? The values indented by tabs? The formulas? What if you have more than one page in the xls file?
If what you really whant to do is to store the file in the database use a BLOB and store it as bytes.
