IX500DistinguishedName::Encode method (certenroll.h)

  • Article

The Encode method initializes the object from a string that contains a distinguished name. This method is web enabled.

Syntax

HRESULT Encode(
  [in] BSTR          strName,
  [in] X500NameFlags NameFlags
);

Parameters

[in] strName

A BSTR variable that contains the string to encode.

[in] NameFlags

An X500NameFlags enumeration value that specifies the format of the encoded value.

Note  The following flags are set automatically:
  • The default value specified in Certenroll.h is XCN_CERT_NAME_STR_NONE.
  • If you do not specify XCN_CERT_NAME_STR_FORWARD_FLAG, then XCN_CERT_NAME_STR_REVERSE_FLAG is automatically applied.
  • If you do not specify XCN_CERT_NAME_STR_DISABLE_UTF8_DIR_STR_FLAG, then XCN_CERT_NAME_STR_FORCE_UTF8_DIR_STR_FLAG is automatically applied.
  • XCN_CERT_NAME_STR_ENABLE_PUNYCODE_FLAG is automatically set regardless of any other flag you specify.
 

Return value

If the function succeeds, the function returns S_OK.

If the function fails, it returns an HRESULT value that indicates the error. Possible values include, but are not limited to, those in the following table. For a list of common error codes, see Common HRESULT Values.

Return code/value Description
E_OUTOFMEMORY
