One of the big changes for ASP programmers moving from VBScript to Visual Basic .NET is the introduction of stronger typing of variables. Although it was possible to require declaration of variables in VBScript, it wasn t possible to declare specific types. Statements such as the following were possible: Dim X X="Hello There" X=7 Response.Write(X) In this example, the variable X is set to a string, and in the next line, it s set to an integer. The result of the Response.Write method is a string containing the number 7. This is possible because all variables in VBScript are the Variant type. To help catch potential data conversion errors, Visual Basic .NET has a new statement named Option Strict that is stricter than Option Explicit. Using Option Strict will cause Visual Basic .NET to generate an error if a data type conversion results in data loss, if a variable is undeclared, or if a variable is late bound.. This isn t news to most non Visual Basic programmers, but for Visual Basic .NET programmers trying to create professional, reliable applications, it s a huge step forward.
