See Using the samples for help on compiling, setting up the debugger, and running the sample (either an exe or dll).
Open the Visual Studio 2005 solution file and build the project. This will add the custom object into the Developer Samples component category as Address Inspector.
On the ArcMap Customize dialog box (choose from the Tools menu, then Customize), click the Commands tab and click the Developer Samples commands category.
From the Developer Samples commands category, drag and drop the Address Inspector tool onto a toolbar.
Add an address locator and its reference data to the ArcMap document.
If there are multiple address locators in the map document, set the ArcMap document's current address locator by selecting the address locator on the Find dialog box. The Address Inspector tool will be enabled when there is an active address locator.
Click the Address Inspector tool and click the map to display the address at that point. Pause the mouse pointer on the point and a ToolTip box with the address will display.
