Change database name in runtime (VS 2005)

I have a report in Visual Studio 2005. I implemented it with assistant
designer.
When this report don't find database shows a window:


--------------------------------------------------------------------------------
database connection

--------------------------------------------------------------------------------
- Server name : c:\mydatabase\name.mdb (this text box is disabled)
-
- Database: c:\mydatabase\name.mdb (this text box is disabled)
-
- Login: (this textbox not disabled)
- Password: (this textbox not disabled)

--------------------------------------------------------------------------------

How I can modify content of textboxes "Server name" and "Database" in
runtime

I'm looking for around and I don't find anything. Thank you!
