Please help link the files? I shall get my magic compiler wand out and use it to link these files without the compiler you use....

Tell us what compiler you are using and we may be able to help.

i use my <microsoft Visual c++ 6.0> to do this
and i need to open in the <Microsoft Visual Studio.NET 2003> ... how to link this ??

Why do you need to open it in Studio.NET? Can you not compile and run it in Visual C++?

Is this homework by any chance?

ya it can run in visual C++..
but i dono how to open in Studio.net....
can teach me ???

But why do you need to open it in Studio.NET if it works fine with Visual C++? I'm not a .NET user so I can't help you there, but there's plenty of people on this board that may be able to help.

then did u know that, how create the main menu to link this all together ??

You might have to create a project, or something like that, and then add the .cpp files to the project. You might be able to find a tutorial about this or something on the internet or perhaps at Microsoft's website.

Create Project. Win32 Console Application. Application Settings > Empty Project.

In Project, Add Existing Item, select all your files. Save All. Build.

If it works, open the .dsp file in VC++ .Net. It will convert it to a .vcproj. Save All. Build. It should work.
