Should someone programming using VB Forms use MVC pattern

I am refactoring some code and am working with another programmer. I suggested refactoring the code to follow the MVC pattern to remove all the plumbing from the forms code and put them into seperate classes such as a controller and model class for database. He disagreed with me saying that VB is not meant for MVC and that we should put the code into DLL's. I agree with DLL's but put the MVC into the DLL's is my opinion. Have I got the wrong idea ?
