CRegKey вроде в МФЦ называлось ...

 

[BadMan]

А можно что ни-будь по проще?(А то я же начинающий)

 

[LIN]

есть способ лучше и проще (но только если вы используете MFC)...
во-первых в функции
SetRegistryKey(_T("MyName");
ASSERT( m_pszRegistryKey != NULL );

if( m_pszProfileName != NULL )
free( (void*)m_pszProfileName );
m_pszProfileName = _tcsdup( _T("MyProgrammName") );
ASSERT( m_pszProfileName != NULL );

 

[LIN]

сорри...недописал...
Если вы работаете с MFC, то есть способ проще…
Во-первых в функции InitInstance(), класса производного от CWinApp необходимо добавить следующее:

SetRegistryKey(_T("MyCompanyName");
ASSERT( m_pszRegistryKey != NULL );

if( m_pszProfileName != NULL )
free( (void*)m_pszProfileName );
m_pszProfileName = _tcsdup( _T("MyProgrammName") );
ASSERT( m_pszProfileName != NULL );

Вся информация записывается в:
HKEY_LOCAL_MACHINE\SOFTWARE\MyCompanyName\MyProgrammName.

Пример для вызова будет такой:
AfxGetApp()->WriteProfileInt(“SerialPortSettings”,”PortNumber”,1);
Или для чтения:
INT mPortNumber = AfxGetApp()->GetProfileInt(“SerialPortSettings”,”PortNumber”,mDefaultValue);
Если такого ключа в реестре нет то, функция вернет mDefaultValue.

А затем, где вам это необходимо воспользоваться следующими функциями:
BOOL WriteProfileBinary(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
LPBYTE pData,
UINT nBytes
);
Parameters
lpszSection
Points to a null-terminated string that specifies the section containing the entry. If the section does not exist, it is created. The name of the section is case independent; the string may be any combination of uppercase and lowercase letters.
lpszEntry
Points to a null-terminated string that contains the entry into which the value is to be written. If the entry does not exist in the specified section, it is created.
pData
Points to the data to be written.
nBytes
Contains the number of bytes to be written.
Return Value
Nonzero if successful; otherwise 0.
BOOL WriteProfileInt(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
int nValue
);
Parameters
lpszSection
Points to a null-terminated string that specifies the section containing the entry. If the section does not exist, it is created. The name of the section is case independent; the string may be any combination of uppercase and lowercase letters.
lpszEntry
Points to a null-terminated string that contains the entry into which the value is to be written. If the entry does not exist in the specified section, it is created.
nValue
Contains the value to be written.
Return Value
Nonzero if successful; otherwise 0.
BOOL WriteProfileString(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
LPCTSTR lpszValue
);
Parameters
lpszSection
Points to a null-terminated string that specifies the section containing the entry. If the section does not exist, it is created. The name of the section is case independent; the string may be any combination of uppercase and lowercase letters.
lpszEntry
Points to a null-terminated string that contains the entry into which the value is to be written. If the entry does not exist in the specified section, it is created.
lpszValue
Points to the string to be written. If this parameter is NULL, the entry specified by the lpszEntry parameter is deleted.
Return Value
Nonzero if successful; otherwise 0.
Соответственно для чтения существуют следующие функции:
CString GetProfileString(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
LPCTSTR lpszDefault = NULL
);
UINT GetProfileInt(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
int nDefault
);
BOOL GetProfileBinary(
LPCTSTR lpszSection,
LPCTSTR lpszEntry,
LPBYTE* ppData,
UINT* pBytes
);
