    adding a header file in VC 6.0

    Hello everyone

    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.

    This adds a header file.
    Code:
    #include "myfile.h"
    Make sure that the implementation and interface to the class is is in the right file (header and source).

    It would be easier to help you if you posted some code.

    You can open the file, then right-click on the page and select "add file to project", and the header will be added and the relevant code compiled.
    Couldn't think of anything interesting, cool or funny - sorry.

    The #include "dice.h" was never the problem. It was always added to the code. But thanks for your time anyway!

    I have added it to the project, and yet I keep getting the following errors:

    Cpp1.obj : error LNK2001: unresolved external symbol "public: int __thiscall Dice::NumRolls(void)const " (?NumRolls@Dice@@QBEHXZ)
    Cpp1.obj : error LNK2001: unresolved external symbol "public: int __thiscall Dice::Roll(void)" (?Roll@Dice@@QAEHXZ)
    Cpp1.obj : error LNK2001: unresolved external symbol "public: int __thiscall Dice::NumSides(void)const " (?NumSides@Dice@@QBEHXZ)
    Cpp1.obj : error LNK2001: unresolved external symbol "public: __thiscall Dice:ice(int)" (??0Dice@@QAE@H@Z)


    I know it is just a linking problem as it's the same code as in the book I am working from. I've been trying to figure this out for 2 days now and I really don't know what to do anymore.

    hi you saying that you still getting the LNK2001 error and you

    saying that you put in the file for example ".h" you will get still

    that error if you don't add the header file at your project but for

    the best result is that every time you compile your project you

    have to make sure that at the class view you have the file in

    there so if you don't have the file in there just go at the top

    project and add a file that you wont this will help you a lot it

    helped me to ok just fallow this things
