OK - Great - and thanks! Now - how do I do latebinding of the Object
Model in C# using createObject. So what do I need to type to get the
example:
----------------------------
Broker.Application ab = new Broker.Application();
string currentPath = ab.DatabasePath;
----------------------------
to work - and what "using" statements etc. will provide the type
interface/suggestions/methods "lookup" when typing code? I've been
at it for almost a week now with no luck, probably mostly due to the
fact that I'm a newbee at using "foreign" COM objects in C# - so it
might be something very simple I'm not getting...
Thanks
