Opening and outputting a text file

[Transmit]

Hi everyone,

I want to open a .txt file and just show it.Not for reading or anything but just showing it when people enter a certain number.
Can anyone tell me how to do this?

and is there a command to close all windows of the application?

This will help you open a file, read stuff in, and then you can print it out to the screen:

You could use a case (switch) statement in a while loop for the user input and when to display, if you need help on that, check out thescripts.com' s tutorial:

http://www.thescripts.com/serversidescripting/c++/tutorials/c++andloops/index.html

That should get you started!

Thanks, but I actually meant opening the .txt file like when you would double click on it.
Sorry if I didn't explain well!

and do you know how to close the whole program? I tried abort() but that didn't gave me what I wanted!

thx already!!

I would guess you are using Windows, and I'm not entirely sure how to open it like that - as it involves a system command to open Word/TextPad/Notepad to open the file up... You can always just open it yourself and print it on the screen (unless you want someone to be able to edit it...). But that shouldn't be too hard to google and find out - I would guess it uses 'windows.h' to run whatever the executable is, and possibly send the file as a parameter? I'm not a windows guy, so I'm not too sure... (sorry!)

You can end the program through return 1 or return 0;

I know how to open it - just pass the system() function a string that has the path to the file you want to open, i.e.

system("C:\\My Documents\\My Folder\\MyFile.txt"); // Double slashes needed because \\ is escape character for \

The system() function takes a string and performs operations just like your regular MSDOS-style command prompt would with the same string. For instance, if I wanted to display the files listed in the folder with my program, I could use the command

system("DIR");

because dir is the command I use in MSDOS to do the same thing.

Closing the file, though...I don't know.

Thanks, Ganon11 - I knew there was a way to do it, but wasn't entirely sure how. And I'm pretty sure whatever user who this file is displayed to is going to have to be in charge of closing it.

I put this:
system("C:\\Sch ool\\Gestructur eerd programmeren\\P rogrammeerproje ct\\Handleiding C.txt");

and it gave me this error:
linking error: undefined symbol _system in module simon.C

any thoughts?

sorry for double post but the 5 minutes expired:

I put the code I just put above ^^ in a switch case statement

so it would look like this:

switch(keuze){
case 1:
system("pathto. txtfile");
break;
case 2:
...
}

I guess that's totally wrong :D Can you specify how to do it a bit more? Thanks man you're being a great help!!!

appreciate it!

Can you post the entire program?

do you have this at the top of your file;

#include "stdlib.h"

[Transmit]

well the program is kinda big and yes I typed:

#include <stdlib.h>

on top!

How big is "kinda big"? We need more to be able to figure this out. If I wrote what I thought was in your code before/after/in the switch statement, I'm pretty sure it would be a completely different program. The entire error message would help too.
