Note
These constants are specified by Visual Basic. As a result, the names can be used anywhere in your code in place of the actual values.
Remarks
The VarType function never returns the value for vbArray by itself. It is always added to some other value to indicate an array of a particular type. The constant vbVariant is only returned in conjunction with vbArray to indicate that the argument to the VarType function is an array of type Variant. For example, the value returned for an array of integers is calculated as vbInteger + vbArray, or 8194.

Example
This example uses VarType to determine the subtype of a variable.
' Initialize variables. IntVar = 459: StrVar = "Hello World": DateVar = #2/12/69# MyCheck = VarType(IntVar) ' Returns 2. MyCheck = VarType(DateVar) ' Returns 7. MyCheck = VarType(StrVar) ' Returns 8.
