This usually happens if your code is throwing an exception in a constructor or the DisabledInit routine (exceptions elsewhere would show "No Robot Code" after running the offending code)

Or more likely:

You are calling a function that is not defined. If you include a function declaration (like you normally put in a header file) but fail to define it (typically what is in a cpp file), you will not get a compile error or warning, simply "No Robot Code" (the compiler assumes that this function exists in an external DLL, when it gets to the robot, if that dll isn't there, it will not execute)
