Hard reset Nokia Express Music 5800

Leave a reply

Here is how to hard reset ( back to factory default settings ) Nokia Express Music 5800.

I suggest you back up your phone content using Nokia suite before proceeding because hard reset will erase everything from your phone. If you have a memory card I suggest you backup the contents and then format it because some of the apps you downloaded trough Ovi Store are actually installed on your memory card and the next time you attach the memory card after hard reset those apps will be installed again.

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

*#7370#

Then for security code enter:

12345

Your phone will restart and after some time booting will 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

Leave a reply

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 )
