.NET Forum / Languages / Managed C++ / February 2008memory breakpoints/buffer overflows in the VC++ 2005 debugger
I have an app written in native C++ using Visual C++ 2005 (pro edition). How can I set a memory breakpoint in the debugger for this app? Or alternatively, is there another source level debugger I can use that will let me set such breakpoints? Note that moving to Visual Studio 2008 is not an option. Does VS 2008 have this feature? Way back in my VAX/VMS days, the debugger had a feature called a "watch point", which would break into the debugger when data at a specified memory address was modified. The debugger did this by write protecting the page containing the watch point, then handling the resultant access violations, completing those that don't involve the watch point and breaking into the debugger on those that do.

Start your project in the debugger. Set some breakpoint where the variable is accessible. Then in the menu: Debug|New Breakpoint|New Data Breakpoint... The specify either the address or the variable name. Depending on the processor, normally 4 data breakpoints are natively supported. PS: Memory(Data)-Breakpoints are a avilable since several years in VS...  SignatureGreetings Jochen My blog about Win32 and .NET http://blog.kalmbachnet.de/
