Visual Basic allows conversions of many data types to other data types. Data loss can occur when the value of one data type is converted to a data type with less precision or smaller capacity. A run-time error occurs if such a narrowing conversion fails. Option Strict ensures compile-time notification of these narrowing conversions so they can be avoided.
In addition to disallowing implicit narrowing conversions, Option Strict generates an error for late binding. An object is late bound when it is assigned to a variable that is declared to be of type Object.
Because Option Strict On provides strong typing, prevents unintended type conversions with data loss, disallows late binding, and improves performance, its use is strongly recommended.
What you can't do with Option Strict On, is accessing members of objects that are not declared as a specific object type. You must have a typed reference.
To store the vb.net for data into an xml file is called Serialization. To load data from xml file to vb.net form is called DeSerialization.
When compiling to the managed code , your source code is translated to microsoft intermediate language code( MSIL), which is cpu-indenpendent set of instructions that can be effectively converted to native code.
Late Binding: runtime binding
Early Binding: compile time binding as compilation is done before executing an application so it is called early binding.
