Exposing .Net classes as COM classes.

[Banjo]

Is that possible and if so how is it done?

.NET can be exposed to COM. the easiest way is to right click on the project choose Add New Item then select the COMClass template. This will create you Class ID. Interface ID and Event ID for COM registration.

ok, but what about existing compiled assemblies (in particular the .Net framework assemblies)? Is it possible to generate COM reg info from a compiled assembly and if not do you know if the framework assemblies have the necessary options turned on?

 

[TheExtreme]

All is possible but not always the Good.

you could write your own Assembly to access the desired functions in the framework and make it COM accesible , then call your assembly from a COM application. remember that the framework would still need to be running on the client. What are you trying to accomplish.

Ok, so I just need to wrapper class. I am aware of the need for the framework.

We were just looking to make use of some of the .Net functionality without needing to re-write a major product from VB6 to VB.Net.
