Hi,
I've already tried the way u describe. Initializing the string in the constructor is ok... but how about assigning the pointer to a function there?
e.g for string,
Table[0].string = "hello";
how bout assigning pointers to functions?

There is a kind of equal sign = as far as I know, but there are several subtulties when dealing with function pointers. When you equal on pointer to another you must make sure that the right pointer points exactly to where you wants it to point, and that at his point there is actually something to which it points. So, when you are getting pointers of your functions you must make sure that there are such functions somewhere in the memory. Try making them all global.
And by the way I have no idea of what you are doing so do not expect me to be of great help. And another thing there is a button upthere like "Reply to this message" so if you reply I will receive your message by e-mail and there is no need by addressing me globally at the discussion board.
