Enumerates the values for the specified open registry key
#include <WinAPIReg.au3>
_WinAPI_RegEnumValue ( $hKey, $iIndex )
| $hKey | Handle to an open registry key. The key must have been opened with the $KEY_QUERY_VALUE access right. This handle is returned by the _WinAPI_RegCreateKey() or _WinAPI_RegOpenKey() function. It can also be one of the following predefined keys: $HKEY_CLASSES_ROOT $HKEY_CURRENT_CONFIG $HKEY_CURRENT_USER $HKEY_LOCAL_MACHINE $HKEY_PERFORMANCE_DATA $HKEY_USERS |
| $iIndex | The index of the value to be retrieved. This parameter should be zero for the first call to the _WinAPI_RegEnumValue() function and then be incremented for subsequent calls. |
| Success: | The string that contains the name of the value, @extended flag will contain the code indicating the type of data ($REG_*) stored in the specified value. |
| Failure: | Sets the @error flag to non-zero, @extended flag may contain the system error code. |
To enumerate values, an application should initially call the _WinAPI_RegEnumValue() function with the $iIndex parameter set to zero.
The application should then increment $iIndex and call the _WinAPI_RegEnumValue() function until there are no more values (until the @extended flag sets to ERROR_NO_MORE_ITEMS (259)).
The application can also set $iIndex to the index of the last value on the first call to the function and decrement the index until the value with index 0 is enumerated.
To retrieve the index of the last value, use the _WinAPI_RegQueryInfoKey() function.
While using _WinAPI_RegEnumValue(), an application should not call any registry functions that might change the key being queried.
