TCP/IP Client server persistent connections

-

So just last week I was moved to another project where I'm gonna be working on a client server program.
So we are going to be using TCP/IP for communication. And its exciting since its been over two years since I last dabbled in networking. Life is looking exciting.
Anyway so the problem was everywhere I looked, I could find only simple networking examples. So I dug in and put together some code to keep a connection alive for back and forth connection. What I did was basically keep the connection open for next request rather than closing it and reopening it.
This enabled me to have a continuous chat like communication between client and server.
Then I spent some time refactoring the code to make it streamlined.
But I still have to add error handling to it. I'll share it here when I have it ready. It was fun!!!

QCalendarWidget CSS Stylesheeting

-
Recently I had to implement a calendar for a TouchScreen application. I resorted to css to modify the calendar widget's appearance so that it would be more accessible. Following is the code that enabled me to get a proper calendar. calendar->setStyleSheet("QMenu { font-size:20px; width: 300px; left: 20px; }"     "QToolButton {icon-size: 48px, 48px; font: 20px; height: 70px; width: 100px; }"     "QAbstractItemView {selection-background-color: rgb(255, 174, 0);}"     "QToolButton::menu-indicator{ width: 50px;}"     "QToolButton::menu-indicator:pressed,"     "QToolButton::menu-indicator:open{ top:10px; left: 10px;}"     "QTableView { font: 30px; }"     "QSpinBox { width: 100px; font: 20px;}"     "QSpinBox::up-button { width:40px;}"     "QSpinBox::down-button { width:40px;}");

[Qt] Compiling ICU with MSVC (Microsoft Visual Studio)

-
Link to original article: http://qt-project.org/wiki/Compiling-ICU-with-MSVC Text highlighted and notes added Compiling ICU with MSVC (Microsoft Visual Studio)     Qt 5 / QtWebkit requires ICU.         Pre-built packages     The ICU Project site [ site.icu-project.org ] provides pre-built packages for MSVC 2010, which should work with compilers too. Anyhow, you have to compile your own version if you want to avoid the MSVC 2010 runtime dependency (because you’re using another MSVC version), or want to tailor the ICU configuration.     download.qt-project.org [ download.qt-project.org ] also hosts packages for MSVC 2012 .
