Memory Access Breakpoint for Large Ranges using VirtualProtect

March 23, 2011

Visual Studio has had hardware-assisted memory access breakpoints for quite some time now—they are called data breakpoints and, unfortunately, can be used only for unmanaged code. WinDbg has a similar feature with the ba command, which is more flexible because it can be configured to fire when a memory location is read, not just written.
