Oh. I know it is possible to make it read more than the first line because I have seen it before.
Thanks, and have a nice day,

I'm pretty sure chaos theory states that that is wholly impossible ;) Perhaps you should add support for multiline files?

Have a nice day,

I just downloaded the program to look at it, and I see a couple things that you should consider.

I haven't tried the program, but I think you should have the character "0" (zero) in the "Alphabet" array (struct?).

Please indent your code.

Here is an indented version with the 0:

I read multiple lines with the ReadLnString command, I just do it multiple times (as many times as there are lines). To write multiple lines, I use the WriteLnString command (again, as many times as I want lines). I am not exactly sure how that would be added to your program, but that is what I do to read and write multiple lines.

For what little I have done, I did something like the following.

Code: Select all

if(OpenFileRead("File.txt", size, handle) == NO_ERR)
{
  until (Sdone == true)  // read the text file till the end
  {
    if(ReadLnString(handle,message) != NO_ERR) Sdone = true;
    //You need to grab the message and write it to another string(or whatever you need to do) all right here.
    //Base it on an increasing variable, like the following lines.
    TotalMessage[i]=message;
    i++
  }
}
I hope you can get something out of that.

Here's something you may find interesting. Often, when I'm doing something like this, I'll create a single image to represent the whole screen, and pass it parameters for values that will change.

Here's what I mean. I created a "main menu" graphic (attached). Pass it three parameters which represent the three menu items you want to show.

Hopefully, this code shows enough for you to understand what I mean...

Code: Select all

  
int Params[] = {0,0,0};

... later in program

    Params[0] = value1;
    Params[1] = value2;
    Params[2] = value3;
    GraphicOutEx(0,0, "TextMain.ric", Params, 0);
Values...
  • 1 Open (read)
    2 Write
    3 Delete
    4 Rename
    5 Options
    0 = no item
This eliminates the need for six of your graphics.

Does that make sense?

This is my version. The problem with Matt's code is that TotalMessage[] can suffer a STACKOVERFLOW [Beethoven's Symphony No. 5 :twisted: ].
Also, you forgot to add a `;` after the `i++`.
