The SetQWORDValue method sets 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 SetQWORDValue(
[in] uint32 hDefKey = HKEY_LOCAL_MACHINE,
[in] string sSubKeyName,
[in] string sValueName,
[in] uint64 uValue =
);
Parameters
-
hDefKey [in]
-
An optional parameter that specifies the tree 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 [in]
A QWORD data value for the named value. The default value is "3".
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.
