[Solved] Problem with QSetting

stevenceuppens

Hello,

is your file.ini empty?
the method
obSettings.value( key, defaultValue ).toString();

if the key doesn't exists it returns your provided default, in this case an empty string.. (maybe a type in your group or key name?)

Did you misspell "server" ?

Hi,

Except the possible typo with Serever, did you save it first once ?

this is my ini file content :

[General]
Server=192.168.1.1

stevenceuppens

did you check the typo in

QString address = obSettings.value(" Serever ","").toString();

? Offline

Yes I have a mistake in mytype server ... serever no server.

but does not work again :(

This is my code see again please :

@
QSettings obSettings("database.ini", QSettings::IniFormat);
obSettings.beginGroup("General");
QString server = obSettings.value("Server", "").toString();
obSettings.endGroup();

qDebug() << "Server = " << server;

Where is database.ini located ?

No specific path !

I can write into this ini file with below code :

QSettings settings("database.ini", QSettings::IniFormat);
settings.setValue("Server", "192.168.1.1");

but for read.... I don't know why doesn't work.

Just a wild idea:

try with foo in place of General for the group name

Can you show me with example ? :)

Before that, just saw something:

@
QSettings settings(“database.ini”, QSettings::IniFormat); settings.setValue(“Server”, “192.168.1.1”);
@

You don't begin the group, is that a missing line ?

but this is not for Read from ini file ! I don't have problem with setValue :)
My main problem is reading from file :(

You just show me how can I read from ini file , maybe I have a little mistake.
Of course my ini file content is :

[General]
Server=192.168.1.1

Why I can't read 192.168.1.1 from server!?

SGaist

The thing is: your writing to the init file and your reading must match.
Using :

@
QSettings settings(“database.ini”, QSettings::IniFormat); settings.setValue(“Server”, “192.168.1.1”);
@

to write, then you must use

@
QSettings settings(“database.ini”, QSettings::IniFormat);
QString server = settings.value(“Server”, “”).toString();
@

to read it back

[edit: corrected my code]

? Offline

No ! error... in QString server = settings.value(“Server”, “”);

I changed it to below format with QVariant

@
QSettings settings("database.ini", QSettings::IniFormat);
QVariant server = settings.value("Server", "");

qDebug() << "Server = " << server.toString();
@

Result is :

Server = "192.168.1.1"

Good work :)
Thank you very much. ;)
