I used to debug VB 6 binaries using VS 2005 few years back. Now I am trying to do the same in VS 2015 but I am not able to. Could anyone please tell me step by step how can I debug VB 6 binaries in VS 2015?
In your VB6 project's Project->Properties->Compile, check "Compile to Native Code," "No Optimization" and "Create Symbolic Debug Info."
In Visual Studio 2015's Debug->Options, check "Use Native Compatibility Mode":
At runtime, in VS2015, attach to the process containing your VB6 executable. At this point, you should be able to set breakpoints and step through the code.
