i toke a photo with my nokia c5-03. now, i pressed the red button when the phone was elaborating the photo... i do not find that photo!!!! it was very very important for me! how can i recover it???...

thank you very much! =)

my program is:
you lauch a comand

sudo shutdown -c now now, how do you insert the root - password ?

for windows

how to program the installation utility of Qt' applications?

thank you!

QString::section(): i am not able to use it.
could you write any examples, please?

if i have: "hello. i am a boy and i am 15 years old", i want "i am 15 years old".

so, here the problem is:
how to use QString::section()? examples in the documentation are unuseful for me...

yes, it is! if i sum "pathInput.readLine();", the machine returns NULL ("")...

void FileTrenner::trennen()
{
if(pathInput->open(QFile::Text | QFile::ReadOnly))
{
QTextStream in (pathInput);
qDebug() << "pathInput vale: " << pathInput->fileName() <<...

'scuse me. i have just edited my thread.. =)

excuse me, return to QString::section(): i am not able to use it.
could you write any examples, please?

if i have: "hello. i am a boy and i am 15 years old", i want "i am 15 years old".

i understood my mistake:



//create a file in qt
QFile file(filepath/file.txt);
file.open(QIODevice::Text | QIODevice::WriteOnly);

thank you.
so, what API do i have to use?

QFile file(path.txt);

QDir mdir;
mdir.mkpath(path.filename());

why does this code create a folder and not a file?

all right! thank you for "lesson"! =)

how should i write the program correctly?

...what does "gdb" means?

i did not understand: what must i do?

0k. thank you!

there is still an error (crash when "open" is clicked):
FILETRENNER.CPP

#include "filetrenner.h"
#include <stdio.h>
FileTrenner::FileTrenner(QWidget *parent) :

what event is emitted when "open button" is clicked?

SIGNAL(?????)
