Stopping Visual C++ debugger

In my Visual C++ application, I need to stop in the debugger when a specific memory location is read. Is there any way to do that?

In the Visual C++ debugger, you can only stop on memory location writes if the data changes. However, the magical new version of WinDBG available at www.microsoft.com/ddk/debugging offers a BA (Break on Access) command that will stop on memory reads. Be prepared to spend some time with WinDBG as it's much harder to use that the Visual Studio debugger.
