Hello, I am attempting this example http://www.codeproject.com/managedcpp/ijw_unmanaged.asp[^] I am newbie so let me clear myself what i understood and where I got stuck. This solution contains three project 1) C # Class Library 2) C++ Managed Library 3) C++ Unmanged Console Application Am I correct? If so Q. after Building 1) and 2) I get two .dlls. In this example's case they are ManagedClasses.dll and ManagedWrapper.dll. HOWEVER to build 3) I need four items, the above two .dll files, IManagedWrapper.h file AND ManagedWrapper.lib file. CAN SOMEONE PLEASE TELL ME HOW TO MAKE .lib file out of 2) ? Q. another question i have is about how to make this projects? I mean When I create a C # library project in .NET 2005 it won't let me include System.Windows.Forms. The included Project sample with the link above somehow gets around it. Can someone explain me how? Also How is 2) (C++ Managed Library ) created? in .Net? when I tried making one.. I ended up with six default files. :( Do i just delete them? Thx a lot Sameep
