hello metRo_

it will be great if you let the discussion board know what are the errors you are facing, going through code may take time and all will not like so just compile the application and let us know what are the errors. :-)

Qt Mobility is part of Nokia Qt SDK if that was a question.

Error if i debug to desktop:

If i debug to phone it's ok, the aplication load but doesn't do nothing.

And in Qt Creator how can i do to Qt Creator reconize it:

#include <qnetworkconfigmanager.h>
#include <qnetworksession.h>
QTM_USE_NAMESPACE

It compile but editor underline it and say: no such file or directory

Qt Mobility is not available on desktop (not really true for Linux desktops). You should include QNetworkConfigManager and QNetworkSession as it's more elegant way of doing it. Make sure that these file exist in directory, where Nokia Qt SDK is installed. What is your desktop platform?

[metRo_]

Windows vista, i can find the files in Nokia Qt SDK folder

How i tell qt where it "#include <QNetworkConfigurationManager>" is?

Have you added network module in to your .pro file

Add this line into your .pro file
QT += network

hope this may be useful for you.

i already added, thanks

QNetworkConfigurationManager is part of Qt Mobility Bearer API so
you should add
CONFIG += mobility
MOBILITY = bearer
However, it was already mentioned in the Wiki example.

Rather than a screen shot of "issues", click on "Compile output" and copy/paste the log from there (though don't paste the whole thing, just relevant sections).
