Answer 1

Depending on what you are trying to achieve you may also 'control' Excel via (OLE) Automation from another application such as Access or Word or from your own application written in another environment such as Visual Basic (6). It is also possible to achieve this via .Net using a language of your choice (although some are easier to implement than others).

Are you wanting to control Excel from an external application or simply trigger a VBA macro in an existing workbook from the outside?

Again, depending on your intention, the workbook could have an Auto Open macro which could be conditional run based on an external value (say an ini file or database value).
