Enumerating registry subkeys (complete)

TheMSsForum.com: The Microsoft Software Forum

... sorry I post the prev msg by mistake ...

Hi All,
I am trying to enumerate the subkeys of a given registry
key, but unfortunately I still have no luck.

Here is the code:

#define DIM_MANAGEMENT_PATH 512
...

int i;
unsigned long dim;
HRESULT ret;
HKEY key;
wchar_t child[DIM_MANAGEMENT_PATH];
wchar_t fullName[DIM_MANAGEMENT_PATH];

RegOpenKeyEx(
HKEY_LOCAL_MACHINE,
//fullContext,
TEXT("Software"),
0,
KEY_ENUMERATE_SUB_KEYS,
&key
);

if (key == 0) {
// some error handling
goto finally;
}

for (i=0; i<*size; ++i) {
dim = DIM_MANAGEMENT_PATH;
ret = RegEnumKeyEx(key, i, child, &dim, NULL, NULL,
NULL, NULL);
if (ret != ERROR_SUCCESS) {
LOG.debug(TEXT("Not NULL"));
if (ret == ERROR_NO_MORE_ITEMS) {
break;
} else {
// some error handling
goto finally;
}
}

LOG.debug(child);
}

*size = i;


finally:

if (key != 0) {
RegCloseKey(key);
}

What I get is that RegEnumKey always returns 183 (something
like "it is not possible to create a file if it is already
open).

What am I doing wrong?

Thanks in advance.

I have found something. The code below is correct, so the
problem is somewere else.
