vbArray

8192

Note: These constants are specified by Visual Basic for Applications. 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. If an object has a default property, VarType(object) returns the type of the object's default property.

Example

Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.

This example uses the VarType function to determine the subtype of a variable.

Dim IntVar, StrVar, DateVar, MyCheck
' 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.
