Hello. I'm Ivo from Brazil!
Sorry my english!
I have some questions...
I have a text file with 288 lines (one quote per line) (quotes.txt)
I need one script for RANDOMIZE and displays this quotes.
It´s possible to embbed this file (txt) to a project?
It´s possible to READ, RANDOMIZE the quotes and SHOW the result (from a text file?) when press a button? ex: "next message"
-------------------------------------------------------------

Thanks!

Hello Ivo.
Welcome to DW/Opus forum.

'Yes' it is possible.
The 'how to do it' depends on what you mean by randomize. Do you care if there would be a repeat display of a quote?

It seems you have some programming and scripting skills, true? Are you familiar with or comfortable with Arrays?

So let me think on this and find some posts here that cover the pieces for a solution:
* read file line be line (quote lines)
* generating a random number (which line to go to)
* storing an Array of 'visited lines' (if 'no repeat' is required feature) This also allows User to exit and return, with the Pub 'remembering' what was previously displayed.
* including a resource file, e.g. quotes1.txt, with the published Pub (best if you read User Guide and helpfiles on "Additional Resources" and also the "publishing" process/options)

I'll get back in next day or so.

[EDIT:] If anyone else has some pointers, examples, help in the meantime... please do post.

ps. thanks for including Profile info. Good to add some PC/system info for future.

First, the 'Read lines from file' part. There are a couple methods.
1) are you familiar with the basic, simple OpusScript method for read line after line. The basic concept is this: OpenFile()... then ReadLine(), ReadLine(), ReadLine()...
-- this is mostly useful for reading-in the file content serially, whether you display one line at a time or you populate a larger text box with several lines.

2) I'm going to suggest a somewhat different approach. Actually, it is the same method as above but instead of placing the text in a textbox on the page, populate a ListBox object.

'Why?'
Because you will have the ListBox either positioned 'off-page', or otherwise make it 'Hidden'. You will later use the INDEX feature of the ListBox as a way to access any line you choose. Or that the random value specifies (this is what will make this solution 'simple').

So first... populate a ListBox. You can keep is 'Visible' for now (hide it later).
Here's an example:
viewtopic.php?t=2477&highlight=listbox+text
(the discussion is about other things, but the basic example should pave the way for you)

and: viewtopic.php?t=2015&highlight=listbox+text
(no example here, but shows the script)

viewtopic.php?t=3801&highlight=readline+file

This one is a bit more involved (and the added complexity may get in the way). But maybe just viewing it will give you some confidence how the 'selection' part works.
Sample IMP: viewtopic.php?t=3632&highlight=listbox+text

- - - - -
So once you have the ListBox populated with your textlines, all you need to do is generate a random number between 0 and 287... then use that value as the index number for the ListBox selection command.

Search the forum for: generate random number (or similar search).
Otherwise the scripting for 'random' is fairly straight forward.
The ListBox selection (by button click & index value) is illustrated in that 'tickbox' example, and probably in others. That one selected line is displayed in a separate, standard textbox object.

You askedbut then you say 'no' to "...include a resource file"
'Yes of course' you can include your text file with 288 quotes. And the way to do it is specify that file as an additional resource (a couple of ways to do that).

Let us know if you need more help.


BTW... there are a number of relevant threads and useful examples --- from developers working on 'quiz' or 'quizzes' (presenting questions to students, etc... randomnizing multiple choice tests, etc.). That's another area that may provide some methods and pieces.
