SetQWORDValue method of the StdRegProv class

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.
