dll

Hi

I have a C++ console Exe which does some progamming. Now i wanted to write a C# GUI which does some of the programming that the C++ exe does. I was thinking of few approaches,

Write the C# GUI with all programming in C++ done from scratch.(I do not want to do this for the amount of rework it entails)
Build a C++ dll which does the programming and have it imported in GUI app.(Now here i have a concern. How do i capture the output of the routines in c++ dll and display it in GUI? Should i return the output as string for every routine that the app calls.? Since i dont know managed c++ iam going to build an unmanaged C++ dll. )

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
