Congratulations on being accepted, we are delighted that you are going

I think you are on the right track :-) However you are jumping forward a 
number of steps :-)) ( and I like small manageable steps that my puny 
brain can process )

Also I think we need to distinguish between defining an object as a 
certain type and additionally defining an 'instance' of that type

so... something like

a) Dim filepicker as new com.sun.star.ui.dialogs.FilePicker ' to declare 
a variable pointing to a new instance
b) Dim filepicker as com.sun.star.ui.dialogs.FilePicker ' for just 
declaring a variable

but... "com.sun.star.ui.dialogs.FilePicker" is a service and not a type 
( and currently there is no afaik way to get the primary interface 
associated with a service from a service name )
But I like your idea and when the bones of the support is in place I 
think we can think about some shortcuts and possibly getting some 
information in the registry that would allow what you suggest to be possible

Personally though I think we need to start with b) it is sort of the 
'base' usage, so..  something like

Dim filepicker as com.sun.star.ui.dialogs.XFilePicker3

and yes the above is quite a mouthful ( but.. for a further step we 
could introduce some namespace magic ) and get

Dim filepicker as ui.dialogs.XFilePicker3

or even

Dim filepicker as XFilePicker3

(and eventually with some help from a tweaked registry )

Dim filepicker as FilePicker '( which basic would understand and Dim 
filepicker as com.sun.star.ui.dialogs.XFilePicker3 )

But... lets talk about this maybe tomorrow, we should meet up in anycase 
to just even say hello. I will try to write some very rough ideas of 
where to start with this, we can then discuss that in some more detail

Once again, congratulations and welcome

Noel


ps. good choice of example
