How to write a managed wrapper class for a unmanagedDialog class in VC++?

I have a dialog application that is created using VC++ 6.0 and a Windows form application using .NET 2003. I'd like to access the Dialog from the form. I have tried every thing I know to write a wrapper class for the dialog class but failed. Would someone here help me out on this?
Thanks

Well, you don't say what you tried and how it failed.
Would someone here help me out on this?
Assuming that your resides in a DLL and exposes a flat interface, you have
at least three ways to go:

1) Use Platform/Invole aka P/Invoke aka P/Invoke to call from the managed
code to unmanaged code

2) Use "It just works" aka IJW aka C++ interop in place of Platform/Invoke

http://msdn.microsoft.com/library/de...onServices.asp

3) Wrap up the native code into a COM object and use the framework's support
for COm
