MustOverride methods must be declared in MustInherit classes. For example, the following code fragment declares an object variable to hold an object returned by the CreateObject function: You should use early-bound objects whenever possible, because they allow the compiler to make important optimizations that yield more efficient applications. If an inherited property or method has to behave differently in the derived class it can be overridden. Therefore, the method or property is not affected by overriding in a derived class. Query expressions are a single line of code; you can just append additional query clauses to the end of the query. 18 Unique Excel Spreadsheet Project Ideas.
