How can I determine if an object variable is Nothing.
Dim appMapPoint as Object
Set appMapPoint = CreateObject("MapPoint.Application")Set appMapPoint =
CreateObject("MapPoint.Application")
Later.... Set appMapPoint = Nothing
Here is why:
I am automating MapPoint via Access/VBA. I always set the map application
object to Nothing when I close it; however, I now need to block certain user
functions (like opening another map) if the instance of MapPoint is still
open. I thought perhaps I could check the state of the Object variable.
Like a dummy, I tried this: If appMpoint = Nothing Then
....of course, to no avail.
