For retrieving the iOS device UUID we need to call uniqueIdentifier that helps us in retrieving the UUID of the device.

[[UIDevice currentDevice] uniqueIdentifier]

Guys whoever want to create apple id freely for learning and downlading the latest SDK and for other iPhone learning activity you need to go to http://developer.apple.com/devcenter/ios/program/start/register/[^]

Bar button Get click event

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"My profile" style:UIBarButtonItemStyleBordered target:self action:@selector(leftBarButtonEventCatcher)];
[self.navigationItem setLeftBarButtonItem:backButton];

Bar button setting the Image

UIImage *backImage = [UIImage imageNamed:@"button_back_Iphone.png"];

//create the button and assign the image
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setImage:backImage forState:UIControlStateNormal];
[backButton addTarget:self action:@selector(leftBarButtonEventCatcher) forControlEvents:UIControlEventTouchUpInside];
//set the frame of the button to the size of the image (see note below)

backButton.frame = CGRectMake(0, 0, backImage.size.width, backImage.size.height);

//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem= customBarItem;

It is very easy to get distance between two GPS Location but It is very difficult to get angle between two GPS positions.

Here is the Mathematics for retrieving angle between two GPS location.

double PoiModel::findAngleFromNorth(double lat1, double long1, double lat2, double long2)
{
//Convert input values to radians
double Lat1_Rad = DegToRad(lat1);
double Lon1_Rad = DegToRad(long1);
double Lat2_Rad = DegToRad(lat2);
double Lon2_Rad = DegToRad(long2);
double xvalue, yvalue;

xvalue = sin(Lon2_Rad - Lon1_Rad) * cos(Lat2_Rad);
yvalue = cos(Lat1_Rad) * sin(Lat2_Rad) - sin(Lat1_Rad) * cos(Lat2_Rad) * cos(Lon2_Rad - Lon1_Rad);

// Bearing_Radian = ATAN2(COS(Lat1_Rad) * SIN(Lat2_Rad) - SIN(Lat1_Rad) * COS(Lat2_Rad) * COS(Lon2_Rad - Lon1_Rad); SIN(Lon2_Rad - Lon1_Rad) * COS(Lat2_Rad))
double Bearing_Radian = atan2(xvalue, yvalue);

//Bearing_Radian = fmod(Bearing_Radian + (2 * M_PI), 2 * M_PI);
Bearing_Radian =(Bearing_Radian + (2 * M_PI)) % (2 * M_PI);

return Bearing_Radian;
}

double PoiModel::DegToRad(double degrees)
{
return degrees * ( M_PI / 180);
}

Java certification sites ::

http://www.javaprepare.com/notes/intro.html
http://www.jchq.net/faq/jcertfaq.htm

C++ sites ::

www.tenouk.com
www.parashift.com

For VC++ ::

you need to change linker option from /SUBSYSTEM:CONSOLE to /SUBSYSTEM:WINDOWS. This prevents showing Console window. After changing this option, possibly you need to change /ENTRY option to tell to the linker that your program has main and not WinMain entry point.
Playing with these options, it is possible to hide console window in console application, or add console window to Windows application.

For C# ::

Just use the WindowStyle property and set it to Hidden
for example ::
Process process = new Process();
process.StartInfo.FileName = "test.exe";
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.Start();

Url can be helpful for multimedia application in VC++.

----------------------------- ShellExecute -------------------------

For executing any application from Executable in VC

ShellExecute(NULL,NULL, "iexplore.exe","http://www.test.com", NULL, SW_SHOWNORMAL);

------------------------------- Registry -----------------------------

For opening registry RegOpenKey or RegOpenKeyEx functions. If the keys need to be created, the RegCreateKey and RegCreateKeyEx functions do the job. Ex is for 32 bit versions

The RegSetValue and RegSetValueEx functions allow the settings of a value to be modified, while RegQueryValue and RegQueryValueEx retrieve the current setting of a value.

Example ::

RegCreateKeyEx(lPredefinedKey, sNewKeyName, 0&, _ vbNullString, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, _ 0&, hNewKey, lRetVal)

RegOpenKeyEx(HKEY_CURRENT_USER, sKeyName, 0, _ KEY_QUERY_VALUE, hKey)

HKEY hRegKey = NULL;
DWORD regDword;
// creates or opens(if key already exists) the registry key

RegOpenKeyEx(HKEY_LOCAL_MACHINE, MY_LOGGER_REG_PATH, 0, KEY_QUERY_VALUE, &hRegKey) ;

if (hRegKey == NULL)
RegCreateKeyEx(HKEY_LOCAL_MACHINE, MY_LOGGER_REG_PATH, 0, NULL, REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 0, &hRegKey, &regDword);
