You can then do renaming by copying the contents of a key to a new key, and deleting the old one. Here's one I just knocked up. Total pain in the ass isn't it! Hopefully when we get a standard config system on Linux it will be a bit better designed.... /* Copy the values and subkeys of the registry key source to dest recursively. * Returns NO_ERROR if the copy completed OK, otherwise it propagates the error. */ LONG copytree(HKEY source, HKEY dest) { int i = 0; LONG res; /* first of all, copy the values */ while (1) { char valname[MAX_VALUE_NAME]; DWORD valname_size = sizeof(valname); DWORD size; DWORD typecode; char *value; /* determine size of the buffer we'll need */ res = RegEnumValue(source, i, valname, &valname_size, NULL, &typecode, NULL, &size); if (res == ERROR_NO_MORE_ITEMS) break; if (res != NO_ERROR) return res; value = HeapAlloc(GetProcessHeap(), 0, size); if (!value) return ERROR_OUTOFMEMORY; valname_size = sizeof(valname); /* RegEnumValue blasts this even though it doesn't need to */ res = RegEnumValue(source, i, valname, &valname_size, NULL, &typecode, value, &size); if (res != NO_ERROR) return res; res = RegSetValueEx(dest, valname, 0, typecode, value, size); if (res != NO_ERROR) return res; HeapFree(GetProcessHeap(), 0, value); i++; } /* for each subkey, create an equivalent under dest then recurse into ourselves to complete the copy */ i = 0; while (1) { HKEY subkey_src, subkey_dest; char name[MAX_KEY_LENGTH]; DWORD size = sizeof(name); FILETIME time; res = RegEnumKeyEx(source, i, name, &size, NULL, NULL, NULL, &time); if (res == ERROR_NO_MORE_ITEMS) break; if (res != NO_ERROR) return res; /* create the destination subkey */ res = RegCreateKey(dest, name, &subkey_dest); if (res != NO_ERROR) return res; /* open the source subkey */ res = RegOpenKey(source, name, &subkey_src); if (res != NO_ERROR) return res; /* perform the recursive copy */ res = copytree(subkey_src, subkey_dest); if (res != NO_ERROR) return res; i++; } return NO_ERROR; } Hope that helps! thanks -mike
