    encryptionKey As String
) As String

Parameters

• cookieData
  [C++]

  [in] A BSTR that contains the cookie.

  [Visual Basic]

  [in] A String that contains the cookie.

• encryptionKey

Return Value

[C++] This method returns an HRESULT indicating whether it completed successfully. See the Error Values section for more details.

[Visual Basic] If this method completes successfully, it returns a String that contains the user ID.

Error Values

[C++] This method returns S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

[Visual Basic] This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

The following table shows the custom COM error that this method can return.

[C++] Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.

[Visual Basic] Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.

Remarks

[C++] The pbstrUserID parameter contains valid data only if the method completes successfully.

The cookie data is always URL decoded.

This method is available when the MSCSAuthManager object is instantiated outside of the context of an ASP script.

This method is similar to the GetUserIDFromCookie method, but allows you to specify the encryption key. This enables the decryption of persistent cookies when the ticket encryption keys have changed. Retaining the user ID when replacing outdated cookies prevents the Business Analytics System from treating the returning user as a new user.

Example

' vUserID is a Variant.
' oAuthManager is a AuthManager object.

vUserID = oAuthManager.GetUserIDFromCookieAndKey(sCookieData, sKey)
