Why not just use SHFileOperation()?

Because I suspect on Windows Mobile it is not supported -- I need to write program for both Windows desktop and Window CE.

I was not concerned with privileges. I was simply suggesting replacing dozens of lines of code with a single one.

By using SHFileOperation() instead.

Thanks DavidCrow,

This function is convenient to use, but I am not sure whether we can use it on Windows CE.

getline()

Hello,
I am using the command getline() to get the line of a text file.. But i think i have a problem with this command.
Here is how i used it in my programme:
getline(list,s1);
list is

fstream list;<br />
list.open("listfile.txt",ios::in);

and s1 is string s1;
The included libraries of my programme are :

#include <cstdlib><br />
#include <iostream><br />
using namespace std;<br />
#include<fstream><br />
#include<stdio.h>  <br />
#include <time.h><br />
#include <sstream><br />
#include<string>

I was wondering if getline() had a limit of character by line, and if it is so, how can i know its limit and change it.
Thank you

I am not sure at 100% but I think the getline () works buffering, so it is supposed to get the text until it founds an "\n" to change line.

About your includes... write the lines with a space between "<" and ">" I mean... you have to write i.e. #include < math.h > because if not, the web trys to use it as < pre > and so on...

Is it so hard to go back and preview your post to make sure it reads exactly as you expect?

Sarcasm and apologies are not necessary. I was merely letting you know a way of increasing your chances of receiving help.

I have been posting message since a week. I didn´t take time to look at every button... That´s all.

DavidCrow wrote:

I thought that too, but a simple " Sigh | :sigh:

hum..." seemed not to be enough because you felt posting a new message...

However you didn´t "merely letting [me] know a way of increasing [my] chance of receiving help. "
I "paid" for each person who did that. You didn´t need to say "is it so hard to..." just give me the information. That´s all. There is no need of being haughty with me.

The word "hum" is meaningless when no context is provided.

Why would you expect to receive help when over half of your code snippet cannot be read? Format your code properly, and double-check your grammar, before committing your posts. You'll receive much more help as a result.

I know that i did not post the message properly, i should have done a preview before sending it, there is no need to argue about this, i agree with you.
However this is a useless conversation, I will do a preview before posting a message that´s all...

Usually, Windows applications relies on the Common Dialog Library's Print Dialog Box to let user browse for the available printers.
