Using Watch Expressions and Contexts

A Watch expression is essentially what its name implies; it is an expression whose value you want to watch change while your program runs. The expression may be simple or complex.

A simple expression might consist of a single variable. A complex expression might perform calculations on multiple variables, or even call functions. The only requirement is that a Watch expression must be a legal VB expression. In other words, if you can’t use an expression in a line of code without generating a compiler error, you can’t use it as a Watch expression either.
