After that, it just goes on putting it into the text file as one big string. I know that works because every part of the string gets put in up until the new line.

myString = myString + "\n"
-
}
-
Hmm, let me think now... -
string myString;
-
string text;
-
if (text == "\n")
-
{
-
myString = myString
-
std::cout << "\n"
-
}
-
That should work.

That should work. Nope, that dosn't work.
Please remember that the newline has to be in a string and that string will be put into a text file.

Where are you getting "text" from (I realise the declaration is immediately before the if here just to highlight how it was declared), but I wondered whether you can post where you give text a value

You see, I'm makeing a decrypter and the encrypter actualy gives every new line a numarical value, so thats whats happening.

Sorry, what I meant is what is the command you are using to fill the variable "text".
In the example you declare it and immediately test it (without assigning it a value). I understand this is for demonstration purposes, but how are you reading a value into "text" in your program.....
Assuming you read it line by line using getline, then you don't even need to test for "\n", simply add a "\n" after every call to getline().

string fileOpen;
-
cin >> fileOpen; //The Path Of The File To Be Opened
-
ifstream fileopen;
-
fileopen.open(fileOpen.c_str());
-
if (fileopen.is_open())
-
{
-
while (! fileopen.eof() )
-
{
-
getline (fileopen,line);
-
text = text + line;
-
}
-
fileopen.close();
-
}
-
else
-
{
-
cout << "The File Was Unable To Open For An Unknown Reason. Please Check The Name" << endl;
-
cout << "You Gave The File And Try Again." << endl;
-
cout << " Program Terminated" << endl;
-
system("PAUSE");
-
return 0;
-
}
That is what I'm using to fill in " text".
But I will try to do that, you know, just add a " \n"

LEt us know if it works (or not) that time it literally put " \n" into the text file..humerous but not functional.

You could incrementally add to the file, that is temp = firstlineline;
then use putline to write temp, set temp to "" and start again

Also, do you ever get the feeling that someone is calling you a geek when you are writing on this site? And third of all, when will my ranking go from newbie to something else?

Thanks alot for your help everyone, but the issue has been resolved. All I had to do was change a little of my code before hand.
Well, thanks. That was the last bug for my program.
But, if any one can tell me how to open the "open" and "close" GUI file dialogs, that would be great for version 1.1!
Just P.M. or email them to me (from my profile, just click on my name for all you newbies out there)
