Why this Error

I am using VS 2003 and I have all my functions implemented however I still keeo getting the following error;

Method not found: Boolean ControleFone.Banco.Bd_Estoque.UpdateSaidaEstoque(Int32, Int32, System.DateTime, System.String, System.String, System.String).

I have this method implemented in my program so why do I keep getting this error!!!!

If you get the error message during compilation, it could be one of two things:

1. You have not properly referenced the Namespace if it's different from your project.
2. You are using the wrong parameter type compared to the method you have defined (meaning, the signatures are different).
