Writes binary data to a value in the registry.

BOOL WriteSectionBinary(
   LPCTSTR lpszSubSection,
   LPCTSTR lpszEntry,
   LPBYTE pData,
   UINT nBytes 

[in] lpszSubSection

A string that contains the name of a registry key

[in] lpszEntry

A string that contains the value to set.

[in] pData

The data to write to the registry.

[in] nBytes

The size of pData in bytes.

TRUE if this method is successful; otherwise FALSE.

The lpszSubSection parameter is not the absolute path for a registry entry. It is a relative path that is appended to the end of the default registry key for your application. To get or set the default registry key, use the methods CWinAppEx::GetRegistryBase and CWinAppEx::SetRegistryBase respectively.

If the key specified by lpszEntry does not exist, this method will create it.
