' Examples of using the CBitly class to use the Bit.ly web service to convert a long Internet URL string to a short one and vice versa with VBA and VB6. ' To use Bit.ly API calls, you need to create an Bit.ly account (free) and get the OAuth authentication access token or user name and API key. ' See the declarations section of the CBitly class for additional details. ' ' To use this example, create a new module and paste this code into it.
