VBA code to start typing in field?

I have a somewhat complicated problem since I am working with a macro provided by someone else. It requires logging on, 3 times. Once the macro runs, a COM object appears. Not in VBA so I can't use the property manager to easily populate fields. However, the cursor begins in the appropriate field where the password must be entered.

Is there vba code to enter text in a field the location of the cursor for an external object? Sorry if my vocabulary isn't on par for this. Unfortunately I can not find further information on the properties of the object.

Probably use SendKeys can help you solve the problem.
But it is uncertain method.
