Working with Empty and Null
Empty and Null are values that can exist only for Variant variables. They're different from one another and different from zero or a zero-length string. At times, you need to know whether the value stored in a variable is zero, a zero-length string, Empty, or Null. You can make this differentiation only with Variant variables.Working with Empty
Variant variables are initialized to the value of Empty. Often, you need to know whether a value has been stored in a Variant variable. If a Variant has never been assigned a value, its value is Empty. As mentioned, the Empty value is not the same as zero, Null, or a zerolength string.Your ability to test for Empty in a runtime environment is important. You can do this by using the IsEmpty function, which determines whether a variable has the Empty value.
A Variant variable loses its Empty value when any value has been stored in it, including zero, Null, or a zero-length string. It can become Empty again only by storing the keyword Empty in the variable.
Working with Null
Null is a special value that indicates unknown or missing data. Null is not the same as Empty; in addition, one Null value is not equal to another one. Variant variables can contain the special value called Null.Often, you need to know whether specific fields or controls have never been initialized. Uninitialized fields and controls have a default value of Null. By testing for Null, you can make sure fields and controls contain values.
If you want to make sure that all fields and controls in your application have data, you need to test for Nulls.
