Hello all,

Happy new year !

 

I have a problem with fstream.

Here is my code:

 

fstream myfile ("users\\users.ini");

string line;

if (myfile.is_open()) {

while (! myfile.eof() && nick != line )

myfile >> line;

//HERE STARTS THE PROBLEM

//WRITE A NEW USER

if (line != nick) {

myfile << ios::app;

myfile << nick << "\n"

<< "user=" << nick2 << "\n"

<< "pass=" << pass << "\n"

<< "mail=" << mail1 << "\n";

//HERE STOPS THE PROBLEM

sendmail(nick2, pass, mail1);

sprintf(e, notice, snick, "Your account info has been sent to your e-mail address");

senddata(e);

} else {

sprintf(e, notice, snick, "Account name is taken, please try using another nickname");

senddata(e);

}

myfile.close();

}

 

It does only read, but doesn't write. If I use ifstream to open, then I close the file, then I reopen with ofstream and then close it, this way I can write in the file, but I would like avoiding opening and closing 2 times, so I am trying with fstream (which should be both open and close).

 

Thanks to anyone who can help.

When you open your file you need to specify that you are going to write to it. Try opening your file like this:

 fstream myfile("users\\users.ini", ios::out | ios::app);
 

Thanks but wasn't that. It is already implied in fstream. I had to do myfile.clear() to clear the data that was left from an empty line.
