Hi!

This might be just a simple thing that I haven't discsovered, but, how do I save a file in a format that I could open it let's say in notepad and it would be a readable. Same to reading it then.

Like, how do I save a string "hello world" into a file "hello.txt", open it in notepad so it's readable, let's say i'll change it to "hello to you too", load the file in DBpro project and print it to the screen. Is there a way?

I'd like to have a "setup.ini" type file where to declare some variables etc.

hmmmh.. that didn't compile

Here is some code to help you with it.



I would suggest saving the source file first and then reload the source so that you will know where it will write the files. You can indicate in your code where you want the file to be written, but the example simply writes a file in the current directory.

Run the code. Find the 'hello.txt' file and open it. Make the edits to it and save it and then re-run this program.

I hope this helps.

You were probably not using Write String before. The other variable Save and Write options write encrypted data.

If you need any other info on loading/saving files:

(Tutorial 4).

When you write data to a file it's written as binary (except for strings which are written as text). When you open a file in Notepad, you are seeing the ASCII representation of these values. For example, the ASCII value of 'A' is 65 (see here for a list of characters and their values), meaning if you write a byte of value 65 to a file, when you open that file in Notepad you'll see 'A'. If you want to view the values as text, you must write to the file using strings.
