adding a header file in VC 6.0
Could anyone tell me how I can add a user defined header file in Visual C++ 6.0? The file I am trying to add contains a class and for the life of me I have tried everything, looked through this board, looked at the books I have, and I just can't seem to find the answer.
I have tried to just run the file with the header file in the same directory, but it keeps giving me the LNK2001 unresolved external symbol error.
Any suggestions would be very much appreciated.
