What is RCW
How can we use COM Components in .NET?
✍: Guest
.NET components communicate with COM using RCW (Runtime Callable Wrapper). Following
are the ways with which you can generate RCW :-
ã Adding reference in Visual Studio.net. See figure below (Adding reference using VS.NET
2005). Wrapper class is generated and placed in the gBINh directory.
ã Using Type library import tool. Tlbimp.exe yourname.dll.
ã Using interopservices.System.runtime.Interopservices namespace contains class
TypeLib Converter which provides methods to convert COM classes and interface in
to assembly metadata.
ã Make your custom wrappe rs.If your COM component does not have type library
then the only way to communicate is writing custom wrappers. That means
communicating directly with COM components.
