Answer 1

well its quite easy to figure out. Find hte VTAble pointer (In visual studio its the first 4/8 bytes). Then step into a normal call of Test (into the assembler) and you'll see it jump to the Vtable and then to your test function. To override test just replace the pointer where you jumped from in the VTable.
