Read, write, append and delete text file over network.

[000dreamsound000]

Hi
I need help with to access a text file over my local network.
I need to be able to create,read, write and delete the txt file on a specific machine(s) from any computer over the network. The folder where the txt file should be created is enabled for sharing and allows other users on the network to change files (XP Pro on all machines). My code is as follows:

// Writing Local IP to File
  fstream myfile;
  myfile.open ("\\computer_name\\folder_name\\test2.txt");
  myfile << localIP;
  myfile.close();
//////////////////////////////////////////////////////////////////
//Reading from File for Local IP
string line;
  fstream myfile ("\\computer_name\\folder_name\\test2.txt");
  if (myfile.is_open())
  {
    while (! myfile.eof() )
    {
      getline (myfile,line);
      cout << line << endl;
    }
    myfile.close();
  }
 

I don't seem to be able to create, read, write, etc the file using

fstream myfile;
  myfile.open ("\\computer_name\\folder_name\\test2.txt");
 

It seems like the path is wrong although if I paste the path into 'RUN' I obtain the correct folder/file.
Can you please help with this. Also I need help on deleting the file after reading.
Thank you
S

Shouldn't you make the path like this:

  myfile.open ("\\\\computer_name\\folder_name\\test2.txt");
 

kind regards,

Thanks for the quick reply. I had tried ("\\\\computer_ name.....") before and it didn't work. I tried it again but no luck. I can't figure out what I'm doing wrong.
Thanks for any suggestions

Seems like it wasn't liking fstream to write to the txt file in the first place.Changed to ifstream and all fine
Thanks

Did you open your fstream as an output file:

myfile.open ("\\\\computer_name\\folder_name\\test2.txt", ios_base::out);
 

???

No, I didn't use 'ios::' at all. I am just a beginner at C++ and I couldn't tell you what was going wrong. But everything seems fine now.
Thanks for your help.

Thanks for your help.

Also fstream specifies ios::out and ios::in as default. And ofstream-ios::out.
ifstream-ios::in.
