Question

registry programming in C#

Answer 1

[DllImport("advapi32.dll", EntryPoint="RegCreateKeyExW")]
public static extern uint RegCreateKeyEx
(uint hKey, string lpSubKey, int Reserved,
string lpClass, uint dwOptions, uint samDesired,
ref int lpSecurityAttributes,
ref uint phkResult, ref int lpdwDisposition);

the call
uint result = Auth.RegCreateKeyEx(Auth.HKEY_CURRENT_USER, opkey, 0, null, Auth.REG_OPTION_VOLATILE, Auth.KEY_ALL_ACCESS, ref securityattr, ref _hkey, ref disposition);
//
// MessageId: ERROR_INVALID_PARAMETER
//
// MessageText:
//
// The parameter is incorrect.
//
#define ERROR_INVALID_PARAMETER 87L // dderror

Note:

the program runs from the Admoinistrator's account.
