I am building the xFrmMgr class from "1001 Things You Wanted to Know About VFP" chapter 10.4 into a project but I am not sure how to use the parameters part of this class. I have an lparameters statement in the init of my form but when xFrmMgr calls the form the form crashes with "Data Type Mismatch" error. Should I not be using lparameter statement in my form? How does the form grab the parameters that are held by xFrmMgr?
