Hello,

Why I compile this, he said E:\projet compress\exDlg.cpp(218) : error C2664: 'RegSetValueExA' : cannot convert parameter 5 from 'char [3]' to 'const unsigned char *' (new behavior; please see help)


DWORD dwType;
HKEY hKey;
LONG retCode;
DWORD dwBytes = 128;
unsigned char szBuffer[256];

retCode = RegOpenKeyEx(HKEY_LOCAL_MACHINE,
                                          "SOFTWARE\\FILE",
                                          0,
                                          KEY_SET_VALUE,
                                          &hKey3);
            RegQueryValueEx(hKey, "subkey1", 0, &dwType,
                              szBuffer3, &dwBytes);
            RegSetValueEx(hKey, "subkey2", 0, REG_SZ, "ab", 14 );
            RegCloseKey(hKey);

Thanks in advance for the response

I can't see where you declair hKey3 but I guess you do it like this

HKEY  hKey3[ 3 ];

now hKey3 is of the type HKEY[ 3 ] ( *char[3]  )

so if you do &hKey3 you have the type char[ 3 ] but you need a pointer.
You could do it like this

&hKey[ 0 ];
