When the OnSelectionChange event is fired I would like to be able to determine if the NewSelection is a PuchPin Object. Is there a way to figure this out. What I would ultimitely like to do is to display the Street Address in a status bar. I appreciate any help.

Dont do delphi but...

In VB:
If TypeOf pNewSelection Is Pushpin Then
.......................
end if

OR

If TypeName(pNewSelection) = "Pushpin" then
.....................
end if

First off.. a quick note.. anything that returns a IDispatch interface usually means it can be one of many things. You can allways refer to the help at msdn.microsoft.com for a list of the things it can be.

Now for the solution

(assuming the SelectionChange event)

Code:

var
  oPushpin: Pushpin;
begin
  if assigned(pNewSelection) then
  begin
    pNewSelection.QueryInterface(IID_Pushpin, oPushpin);
    if assigned(oPushpin) then
      Showmessage('It's a pushpin!')
    else
      Showmessage('It's NOT a pushpin.');
  end;
end;

Thanks a lot! That is exactly what I was looking for.
