AddressOf Operator

AddressOf procedurename

procedurename required: The name of a procedure that is referenced by the procedure delegate

The AddressOf operator returns a procedure delegate instance that references a specific procedure. It is used in the following situations:

If a parameter to a procedure (a VB procedure or a Win32 API function) requires a function pointer (the address of a function), then we can pass the expression:
```
AddressOf functionname
```
where functionname is the name of the function. This function is called a callback function.
AddressOf is also used to create delegate objects, as in:
```
delg = New ADelegate(AddressOf obj.AMethod)
```
AddressOf is used to bind event handlers to events through the AddHandler statement:
```
AddHandler Form1.Click, AddressOf Me.Form1Click
```
