Pointers to Member Functions

[Doug Broadwell]

Thanks Marcel, that fixed that error. Now I'm getting the error:

'pValidator' undeclared (first use this function)

?????
Help again.

[high_flyer]

on which line in the code this error comes?

[Doug Broadwell]

The error is on this line:

Validated_State = (*State_Tbl[Object].pValidate_State)(Requested_State);

The error is on this line:

Validated_State = (*State_Tbl[Object].pValidate_State)(Requested_State);

Doug

But that is the same code you had before when you started the thread...

[marcel]

Validated_State = (State_Tbl[Object].*pValidate_State)(Requested_State);

Who is pValidate_State?
You should call (State_Tbl[Object].*pValidator)(Requested_State);, because pValidator points to State::Validate_State.

What is the point of pointers to functions if you will call the functions directly?

[Doug Broadwell]

Oops, you're right, the actual line that is generating the error is the edited one:

Validated_State = (State_Tbl[Object].*pValidator)(Requested_State);

My mistake in copying/simplifying the code and having 'pValidate_State' instead of the correct 'pValidator' here. It still gets the 'pValidator undeclared' error.

Just realized one problem, I haven't instantiated any State objects yet to point to!

My newbe status reveals itself yet again.
