My new PostState method wasnt declared static.
Typical, I look for hours and find the solution minutes after posting
to this NG.
Funny how posting a message clarifies the mind after the fact. :) Note that
the compiler gave you a poor error message, misidentifying the non-static
member function as a static one:
AfxBeginThread(pDoc->m_StateMachine.PostState,new
SPostStateParams(m_pDoc,static_cast<StateMachineState>(nItem)),THREAD_PRIORITY_NORMAL,0,0,NULL);
Which returns the compile error:
error C2665: 'AfxBeginThread' : none of the 2 overloads can convert
parameter 1 from type 'unsigned int (void *)
Note also that the syntax you used is illegal for forming a pointer to
member:
pDoc->m_StateMachine.PostState
You have to use &ClassName::FunctionName, and VC 2005 will emit an error
for this. If you use the syntax you tried for a static member, VC 2005 will
emit warning C4551, "function call missing argument list". In both cases,
you should use the &ClassName::FunctionName syntax, which is necessary for
the member case and makes things clearer for the static member case.
