Are you using Windows XP? Press Ctrl+Atl+DownArrow, and then Ctrl+Atl+UpArrow. The screen changes its orientation upside down. isn’t it? But how to turn the screen, upside down programmatically?

Get the current DEVMODE by calling -EnumDisplaySettings(). Then change orientation by setting DEVMODE.dmDisplayOrientation and calling ChangeDisplaySettings(). Have a look at the code snippet. Code taken from MSDN.
// Get current Device Mode.
DEVMODE DeviceMode = { 0 };
EnumDisplaySettings( NULL,
ENUM_CURRENT_SETTINGS,
&DeviceMode );
// Change display mode upside down.
DeviceMode.dmDisplayOrientation = DMDO_180;
ChangeDisplaySettings( &DeviceMode, 0 );
// Sleep for 10 seconds.
Sleep( 10000 );
// Change display mode back.
DeviceMode.dmDisplayOrientation = DMDO_DEFAULT;
ChangeDisplaySettings( &DeviceMode, 0 );
Be careful to restore the display orientation back. Or else

Do you remember the old days, where memory was a premium? At that time, unions were used to save memory by merging multiple variables. Gone are the days where we had memory constraints. Now we have GB’s of RAM itself. So are unions just overhead to language now? Or is it still useful?
