Going out on a limb, and assuming you mean "can I take a VC++ 6 project and
work with it in Visual Studio .NET?"...
In general, it should convert OK. However, the VC++ 7.1 (Visual Studio .NET
2003/.NET Framework v1.1) compiler is much tighter on language standards
compliance than was the VC++ 6 compiler, so you may run into situations
where source code will need to be changed before it will compile
successfully.
