IWMSAdminAnonUser::SetUserNamePassword

The SetUserNamePassword method specifies a user name and password for use during the authorization process.

Syntax

  HRESULT SetUserNamePassword(
  LPWSTR  newUserName,
  LPWSTR  newPassword
);

Parameters

newUserName

[in] LPWSTR containing the user name. This cannot be longer than 63 characters.

newPassword

[in] LPWSTR containing the password.

Return Values

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code Number Description
E_FAIL 0x80004005 The original password and user name do not exist.
E_INVALIDARG 0x80070057 The newUserName parameter is NULL, the newPassword parameter is NULL, or the length of the user name exceeds 63 characters.
E_OUTOFMEMORY 0x8007000E The server cannot allocate memory for a new user name.

Remarks

Before this function returns, memory used by the server to store the user credentials is zeroed out so that the user name and password are not saved unencrypted on the computer that is running Windows Media Services.
