This error is very common for people with C++ background (I've already seen
people asking questions about similar code several times):
----------------------------------------------
class Foo{
  public int data;
}

void main()
{
  Foo f; // obviously they try do this way as they got used to it in C++
         // should be a warning here!

  f.data = 1;// Access violation
}

----------------------------------------------
