I have a Qt application which heavily uses MySql Database. Do you know any open source Qt project which uses MySql? I wonder how did they manage database connections?
Comment to Harald Scheirich's Answer:
1-)QSqlDatabase::isOpen() doesn't work properly. http://bugreports.qt-project.org/browse/QTBUG-223
2-)Using QSqlDatabase::open() in order to check database connection when MySql connection is gone very time consuming in my case.
Use Google codesearch to search for QMYSQL.
Is there anything wrong with QDatabase ? We have a fairly large (non opensource) app that uses MySql together with the Qt provided drivers and the QSql infrastructure. It works fine with very little surprises.

I would like to implement a GUI with a terminal emulator (NOT a system shell, but I would like to have command history, etc). I have only found QConsole, which is not actively developed anymore. Does such a widget exist? If not, where should I begin in looking at how to create such a widget?
Check QTerminal .Maybe thats what you are looking for. Else you can emulate a console using QTextEdit.
Lxqt has created such a widget for QTerminal, called qtermwidget. It works well and can be found here: https://github.com/lxde/qtermwidget
I developed a console for SWI-Prolog, one of the leading Prolog implementations worldwide.
Most of the code is required by the complex multithreading model implemented, so would be useless in less specialized environments. But it's actively developed (compatibly with high stability requirements) even if it appears to stale to 2013. I carry on with implementations in my own loqt. No so stable, of course...

Do you know of a robust, free, ideally open source, web service that uses protobuf.
I maintain an Android library for networking and I write samples for every module. For instance, the JSON modules use Github apis to get some data from the network and illustrate the client library usage.
Do you know an equivalent for protobuf ?
Thanks in advance.
Your protobuf module could use this api to access from the android market place:

What library is the best to use for the purpose? Target platform is Linux.
Difficult to tell the best, but i used Qt (QNetworkAccessManager) and a Qt JSON Parser with success.
I picked up libcurl thus it is enforced with SSL certificate validation. Regarding to REST, I am able to send GET and POST requests also. However it is C but not C++ library. But it does not make a big difference for me because the syntax is pretty clear and there are lot of examples.

I have started working on C++ Windows application which needs to fetch Icloud and Yahoo Calendars by connecting to the CalDav servers.
Is there a C++ library that implements this protocol?
Is there a C++ library that implements this protocol?
There's always a number of good opensource libs that implement standardised protocols like CalDav.
They are best hunted on FOSS project hosts (with the help of Google).
Here is afew:-
http://libcaldav.sourceforge.net/
http://trac.mulberrymail.com/repos/wiki/icalendar
https://code.google.com/p/kcaldav/ <- unmaintained but may be usefull
http://www.zarafa.com/ <- you might want to extract the CalDav only code from this
https://code.google.com/p/openconnector/ <- same as above

im starting a new project and for the first time i want to be cross-platform. But the tricky is my project would involve listen server, cryptos etc., etc. So i was wondering what is the best solution for cross-platform development (OpenSSL, instead of MSCrypto etc.) that would be easy to write with VS2010 (yeah the RC). The language is still not specified (depends on witch we would be easier) but im leaning to Visual C++.
In Cross-Platform i mean windows/generic unix compilation.
Qt4 is a complete crossplatform framework, including a very strong socket library.
also Boost.Asio http://www.boost.org/doc/libs/1_42_0/libs/libraries.htm.
The Poco C++ library may be what you are looking for.
