    // --------------------------------------------------------------------
    // This example is for the older and deprecated Walmart v2 API.
    // 
    // Use the v3 API instead: Walmart v3 Get All Feed Statuses

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Demonstrates how to send a request such as the following to get all feed statuses:
    // Also demonstrates how to parse the results.
