Issue with Qsettings

Hi,

I have a problem that I can't find the ini file and it seems that even the default settings are not set.
The declaration:

Code:

---

QSettings *p_projsettings;

---

After it I expect the File created

Code:

---

p_projsettings =  new QSettings("c:temp\MySoft\DCP_MON_INI.ini", QSettings::IniFormat);

---

Code:

---

defaultvalues();
       p_projsettings->sync();
       if(p_projsettings->status()==QSettings::NoError)
       {
           retval=false;
       }
       else
       {
           retval=true;
       }
       qDebug() << "Status ProjSettings:"       << retval;
       return (retval);

---

The status is alway false

Code:

---

void INI_FILE::defaultvalues()
{
    p_projsettings->value("BAUD","230400");
     p_projsettings->value("PORT","COM3");
     p_projsettings->value("PARITY","NONE");
     p_projsettings->value("DATABIT","8");
     p_projsettings->value("STOPBIT","1");
     p_projsettings->value("FLOWCONTROL","FLOW_OFF");
     p_projsettings->value("TIMEOUT","150");
    // qDebug("projsettings BAUD",projsettings->value("BAUD"));
    qDebug() << "projsettings BAUD:"       <<  p_projsettings->value("BAUD").toString();
     p_projsettings->sync();
}

---

Could anybody please tell me what is wrong?

Thanks!

The path to your ini file does not exist. You use \ in string constant. Better use / for path separator or, if you insist on using \ as path separator, you have to escape the \ in the string constant, i.e. replace each \ in your path by \\, i.e.

Code:

---

p_projsettings =  new QSettings("c:temp\\MySoft\\DCP_MON_INI.ini", QSettings::IniFormat);

that's good, isn't it? false is the value you assign to retval if there are no errors.

Do you set any default values?

What is the purpose of this method?
Reading a bunch of keys but not using the read values doesn't strike me as particularily useful.

Thank you for the quick responce!

So far I remember the value function, it delivers the value out of seetings or if not exist it uses the default... but yes you are right somehow I have to write the settings.
I'll look into it...

Thank you very much !

Even with the backslashes properly escaped or replaced with forward slashes (as Ars pointed out) this may still be interpreted as a path that is relative to the current directory on drive C:. Perhaps you should say:

Code:

---

p_projsettings =  new QSettings("c:\\temp\\MySoft\\DCP_MON_INI.ini", QSettings::IniFormat);
