CWinApp::m_pszRegistryKey

Used to determine where, in the registry or INI file, application profile settings are stored.

LPCTSTR m_pszRegistryKey;

Normally, this data member is treated as read-only.

  • The value is stored to a registry key. The name for the application profile setting is appended to the following registry key: HKEY_CURRENT_USER/Software/LocalAppWizard-Generated/.

If you assign a value to m_pszRegistryKey, it must be dynamically allocated on the heap. The CWinApp destructor calls free( ) with this pointer. You many want to use the _tcsdup( ) run-time library function to do the allocating. Also, free the memory associated with the current pointer before assigning a new value. For example:

//First free the string allocated by MFC at CWinApp startup. 
//The string is allocated before InitInstance is called.
free((void*)m_pszRegistryKey);
//Change the name of the registry key. 
//The CWinApp destructor will free the memory.
m_pszRegistryKey = _tcsdup(
   _T("HKEY_CURRENT_USER\\Software\\mycompany\\myapp\\thissection\\thisvalue"));
