sorry sir. My code may confuse you. but i am just trying to get the textbox value of Add.h form and use it in queue.cpp class, but it shows me error like identifier Add is undefined. i just want to know how can i get the object of Add.h class and can use its methods and function in queue.cpp class.
i also try forward declaration but still it is showing that "incomplete type is not allowed.
i have try many way but still can't get any solution.
