Day 6 – A debugger for Reporting Services
Wouldn't it be nice to be able to peek under the hood and see what APIs Report Manager or a custom application calls? This is exactly what the Reporting Services Tracer (RsTracer) sample was designed to handle. RsTracer intercepts the server calls and outputs them to a trace listener, such as the Microsoft DebugView for Windows. RsTracer helps you see the APIs that a Reporting Services client invokes and what arguments it passes to each interface. It also intercepts the server response. Armed with this information, you can easily reproduce the same feature in your custom management application.
