Below are 4 forms. Namely: Form1, EmployeeID, AboutBox and
EnterEmployeeName. I made a class to help in open, write and read from
files called Time. I managed to declare class Time in EmployeeID space, but
could not declare it in EnterEmployeeName. In other words, I can declare
class Time in one space only. I really want to use class Time in both forms
EmployeeID and EnterEmployeeName. Can anybody tell me why I always get
error below, every time I run the program? And how can I use the Time class
in both the above forms?

Allen, you are in the wrong group.

I am not a C++ expert, so I would suggest reposting in a C++ group. I can,
however, tell you WHAT is happening. With the way you are linking Time, you
are ending up with two links, which is causing the compiler to bomb. As I
have only hacked C++ in my career, I am not sure what to tell you to get
past this error, however.

Peace and Grace,

How about making your other classes sub-classes of Time. Then all
times public methods would be available to them.
