Visual Studio: Break on variable change?

Question

I have a member variable struct in a C++ class I'm debugging in Visual Studio 2008 Professional. I would like to break any time the struct changes. Is it possible to do this, or must I look for every possible point in the code it could change, and set breakpoints there?

Answer 1

If you can determine the address of the member, you can set a data breakpoint on it:
