Assigns an object reference to a variable or property, or associates a procedure reference with an event.

Setobjectvar = {objectexpression | Newclassname | Nothing}
' or
Setobject.eventname = GetRef(procname)

Parameters

objectvar

Required. Name of the variable or property; follows standard variable naming conventions.

objectexpression

Optional. Expression consisting of the name of an object, another declared variable of the same object type, or a function or method that returns an object of the same object type.

New

Keyword used to create a new instance of a class. If objectvar contained a reference to an object, that reference is released when the new one is assigned. The New keyword can only be used to create an instance of a class.

classname

Optional. Name of the class being created. A class and its members are defined using the Class statement.

Nothing

Optional. Discontinues association of objectvar with any specific object or class. Assigning objectvar to Nothing releases all the system and memory resources associated with the previously referenced object when no other variable refers to it.

object

Required. Name of the object with which event is associated.

event

Required. Name of the event to which the function is to be bound.

procname

Required. String containing the name of the Sub or Function being associated with the event.

Remarks

To be valid, objectvar must be an object type consistent with the object being assigned to it.

The Dim, Private, Public, or ReDim statements only declare a variable that refers to an object. No actual object is referred to until you use the Set statement to assign a specific object.

Generally, when you use Set to assign an object reference to a variable, no copy of the object is created for that variable. Instead, a reference to the object is created. More than one object variable can refer to the same object. Because these variables are references to (rather than copies of) the object, any change in the object is reflected in all variables that refer to it.

	Copy Code
Function ShowFreeSpace(drvPath) Dim fso, d, s Set fso = CreateObject("Scripting.FileSystemObject") Set d = fso.GetDrive(fso.GetDriveName(drvPath)) s = "Drive " & UCase(drvPath) & " - " s = s & d.VolumeName & "<BR>" s = s & "Free Space: " & FormatNumber(d.FreeSpace/1024, 0) s = s & " Kbytes" ShowFreeSpace = s End Function

Using the New keyword allows you to concurrently create an instance of a class and assign it to an object reference variable. The variable to which the instance of the class is being assigned must already have been declared with the Dim (or equivalent) statement.

Refer to the documentation for the GetRef function for information on using Set to associate a procedure with an event.
