GetQWORDValue method of the StdRegProv class

The GetQWORDValue method gets the data value for a named value whose data type is REG_QWORD.

This topic uses Managed Object Format (MOF) syntax. For more information about using this method, see Calling a Method.

Syntax


uint32 GetQWORDValue(
  [in]  uint32 hDefKey = HKEY_LOCAL_MACHINE,
  [in]  string sSubKeyName,
  [in]  string sValueName,
  [out] uint64 uValue
);

Parameters

hDefKey [in]

A registry tree, also known as a hive, that contains the sSubKeyName path. The default value is HKEY_LOCAL_MACHINE.

The following trees are defined in WinReg.h.

HKEY_CLASSES_ROOT (2147483648)

HKEY_CURRENT_USER (2147483649)

HKEY_LOCAL_MACHINE (2147483650)

HKEY_USERS (2147483651)

HKEY_CURRENT_CONFIG (2147483653)

sSubKeyName [in]

A path that contains the named values.

sValueName [in]

A named value whose data value you are retrieving. Specify an empty string to get the default named value.

uValue [out]

A QWORD data value for the named value.

Return value

In C++, the method returns a uint32 value that is 0 (zero) if successful. If the function fails, the return value is a nonzero error code that is defined in WinError.h. In C++, use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description of the error. You can also look up return values under the WMI Error Constants.

In scripting or Visual Basic, the method returns an integer value that is 0 (zero) if successful. If the function fails, the return value is a nonzero error code that you can look up in WbemErrorEnum.

Examples

The Registry Dumper VBScript sample uses a number of methods, including GetQWORDValue, to to dump registry keys based on specific inputs.

The Multithreaded Remote Registry Gathering with Powershell sample gathers specific subkey values or an entire registry key’s subkey values with powershell and multithreading.
