how can we create a database or questions { a place where some set of pre-defined data is kept } and also to retrieve information randomly and display n the front panel?? 

Anyone please help me out in creating a pre-defined database and retrieving that information randomly

You already started down the simple route: use a simple text file.  Each line in the text file should be a new question.  If you right-click on the Read From Text File, you will see an option to "Read Lines".  Enable that and set your number to read to -1 (read all lines).  You will now have an array of questions.

Now you just have to figure out the randomization.  There are plenty of examples on that, but see how far you can get and let us know where you are stuck.

Hi ivan,

the obtained result form the text file to labview is in different language i.e i mean the result is showing in different format not as it is given in the text file

Does LabVIEW translate the text from one language to another language? I don't believe this… 😄

Does you text contain any Unicode characters? LabVIEW isn't good at handling such char encodings and reads your text as plain ASCII by default!

(Maybe you should provide your VI and an example text file to help us solve your problem…)

help me out how to randomise

There is a random() function in the numerics palette…

different language means .. there is a different format showing in string (result) indicator

Hi Ivan,

unfortunately I can only open VIs for upto LV2014 right now, so you need to down-convert your VI and attach it again (file menu -> save for previous)…

And please also attach your text file!

here i selected some random question in the text file .. also with previous version vi

Try saving in a text format, instead of a Word format. For example, "t_and_d.txt" with the same data will be much easier to parse.

Greetings ! 

i would like to select a random line from the given text file without taking the empty spaces .i.e it is taking empty spaces also though i specified read lines in read from text file icon .

Is there any option to make like 'it should only take the lines upto which i specified but not going beyond which results in empty spaces in the display.

I have a VI that specifically goes through the array of strings and removes the empty strings.  This is what I recommend you do.
