How can I;
1. Check the existence of an exe app in a particular path such as
c:\myfolder\myapp.exe, and
2. Execute the app?

How do I do that?

I need to bind in (thumbnail-sized) pictures into an Access Database
in such a way that there is one picture for each record (abt. 3000

Until now, I have embedded OLE-objects and have inserted each picture
