Typeof Function

---

This standard VB function returns a value indicating whether an object is of a given class.

Syntax

If Typeof objectVariable Is className Then...

Placeholder	Meaning
objectVariable	The object to be tested
className	The class to which the object is to be compared

Returns

The Typeof function returns -1 if the object is of the specified type, 0 if it is not.

Usage

Typeof can be used only in an If statement and cannot be combined with other Boolean operators. That is, Typeof can be used only exactly as shown in the syntax line.

To test whether an object does not belong to a class, use the following code structure:

If Typeof objectVariable Is className Then
   
[Perform some action.]
Else
   [Perform some action.]
End If
