You are possibly talking about an "auto-filling" textbox. The datasource can
be a text file, registry, names of the shell objects(Windows XP can do it for
you provided you follow some COM Interface rules..for details in MSDN) or
even a database(very intensive queries).
Three options are there
1. For shell objects(file/folder names) Windows XP can help you. It even
have a feature of implementing your own data source(if I remember correctly)
2. Implement your own Winform control with pluggable data sources(That would
be great !)
3. Go for third party control like XTras.NET
