QProcess problem: compile well but output error

[jx324]

Hi everyone,

I have a problem as written in title. Here are the codes:

Window::Window()
{

QGroupBox *echoGroup = new QGroupBox(tr("Anscare"));

QLabel *echoLabel = new QLabel(tr("File:"));
QPushButton *browse = new QPushButton(tr("browse.."));
QPushButton *convert = new QPushButton(tr("convert"));
echoLineEdit = new QLineEdit;
echoLineEdit->setFocus();

connect(convert, SIGNAL(clicked()),this, SLOT(runAnscare()));
connect(browse, SIGNAL(clicked()),this, SLOT(getPath()));

QGridLayout *layout = new QGridLayout;
layout->addWidget(echoGroup, 0, 0);

setLayout(layout);

setWindowTitle(tr("WinCares"));
}

void Window::runAnscare()
{
convert->setEnabled( false );

if( process )
delete process;
process = new QProcess( this );

connect( process, SIGNAL(readyReadStandardOutput()), this, SLOT(handleReadStandardOutput()));

process->start( "anscares.exe ");
}

void Window::handleReadStandardOutput()
{
QString string=echoLineEdit->text();
QFileInfo fi(string);
QString name=fi.fileName();
int i=name.size();
name.remove(i-4,4);
process->write(name.toAscii()+"\n");

}

Compile well and when "browse" button is pressed, echoLineEdit can show the path of file. But push the "convert" button, an error occurs: "something wrong with it" :mad:

Can anyone give me some hints?

Thanks.

process->start( "anscares.exe ");
Where is that file located?

Could you post the exact error message?

The executable file was located in the debug folder. The error shows simply :"an error occurs", that's why I cannot solve it.

Anyway, thanks for your reply.

Are you running the app via an IDE? If so, most likely the current working directory is not in debug nor release subfolder but one level up. See

QDir::current()
