Hard Reset: Nokia XpressMusic 5800

Here is how to hard reset (back to factory default settings) the Nokia XpressMusic 5800.

I suggest backing up your phone’s contents using Nokia PC Suite before proceeding, because a hard reset will erase everything on your phone. If you have a memory card, I also suggest backing up its contents and then formatting it, because some apps you downloaded through the Ovi Store may be installed on the memory card. After the hard reset, when you reinsert the memory card, those apps may reinstall automatically.

To hard reset your phone using the on-screen keypad, enter the following code:

*#7370#

When prompted for the security code, enter:

12345

Your phone will restart and, after it finishes booting, it should be as good as new.

CLastError

Small class for resolving and presenting in user readable form the codes from ::GetLastError() Win32 API function. The class has 2 static methods:

void CLastError::Get( const DWORD& dwErrorCode, CString& strErrMessage )
{
	LPTSTR lpErrorText = NULL;
 
	::FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER, 
		0, dwErrorCode, 0, lpErrorText, MAX_PATH, 0 );
 
	strErrMessage = lpErrorText;
	::LocalFree( lpErrorText );
}

The ‘Get’ method supplied an error code will resolve the code to user readable error message and store it in the supplied ‘strErrMessage’ string!

void CLastError::Show( const DWORD& dwErrorCode, const CString& strAppName )
{
	CString strErrMessage;
	Get( dwErrorCode, strErrMessage );
 
	CString strDisplayError;
	strDisplayError.Format( 
		_T("%s encountered an error and needs to close!\n\nError was: %s"),
		strAppName, strErrMessage );
 
	AfxMessageBox( strDisplayError, MB_ICONERROR | MB_OK );
}

The ‘Show’ method supplied an error code will resolve the code to user readable error message and the message will be displayed to the user trough AfxMessageBox() function.

Class declaration:

class CLastError
{
public:
 
	CLastError( );
	virtual ~CLastError( );
 
public:
 
	static void Get( const DWORD& dwErrorCode, CString& strErrMessage );
	static void Show( const DWORD& dwErrorCode, const CString& strAppName );
};

Class implementation:

CLastError::CLastError( )
{
}
 
CLastError::~CLastError( )
{
}
 
void CLastError::Get( const DWORD& dwErrorCode, CString& strErrMessage )
{
	LPTSTR lpErrorText = NULL;
 
	::FormatMessage( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER, 
		0, dwErrorCode, 0, lpErrorText, MAX_PATH, 0 );
 
	strErrMessage = lpErrorText;
	::LocalFree( lpErrorText );
}
 
void CLastError::Show( const DWORD& dwErrorCode, const CString& strAppName )
{
	CString strErrMessage;
	Get( dwErrorCode, strErrMessage );
 
	CString strDisplayError;
	strDisplayError.Format( 
		_T("%s encountered an error and needs to close!\n\nError was: %s"),
		strAppName, strErrMessage );
 
	AfxMessageBox( strDisplayError, MB_ICONERROR | MB_OK );
}

Unknown Undo/Redo Error

This happened to me couple a days ago using Visual Studio .NET 2003 developing an old ASP.net application in Windows  XP Mode. Using product released 9 years ago on a newer OS has it’s charms.

Unknown undo / redo error.

How to fix it: Re install the IDE ( on 2 out of 3 machines this seems to resolve the problem )  or better, upgrade your project to more recent version of Visual Studio and enjoy all the benefits. As for the company I work for we finally did the upgrade ( Visual Studio 2010 )
