_WinAPI_RegisterClassEx($sClassName, $sCallbackFunction, $hIcon=0, $hCursor=0, $iBkColor=$COLOR_BTNFACE, $iStyle=$CS_DEFAULTSTYLE)

$sClassName -				Classname
$sCallbackFunction - 		WindowProc callback function
$hIcon - 					Handle to a icon which will be be used as the window icon (Default = application icon)
$hCursor - 					Handle to cursor which will be used as the window cursor (Default = arraow cursor)
								Use _WinAPI_LoadCursor() [also included with this UDF] to load a system cursor:
									
									$CURSOR_ARROW
									$CURSOR_IBEAM
									$CURSOR_WAIT
									$CURSOR_CROSS
									$CURSOR_UPARROW
									$CURSOR_SIZENWSE
									$CURSOR_SIZENESW
									$CURSOR_SIZEWE
									$CURSOR_SIZENS
									$CURSOR_SIZEALL
									$CURSOR_NO
									$CURSOR_APPSTARTING
									$CURSOR_HELP
									
									Example: _WinAPI_LoadCursor(0, $CURSOR_IBEAM)
									Do not use the $IDC_ constants declared in Constants.au3 

$iBkColor - 				RGB color code of window background color
$iStyle - 					Class style. A combination of these values: (Default = $CS_DEFAULTSTYLE)
								
								$CS_VREDRAW
								$CS_HREDRAW
								$CS_DBLCLKS
								$CS_OWNDC
								$CS_CLASSDC
								$CS_PARENTDC
								$CS_NOCLOSE
								$CS_SAVEBITS
								$CS_BYTEALIGNCLIENT
								$CS_BYTEALIGNWINDOW
								$CS_GLOBALCLASS
								$CS_DROPSHADOW

Function: Creating a class which can be used with CreateWindowEx, and others
