i want to type the path manually in folder browser dialog, like file browser dialog.

Why you wanna do that, use the FBD object to get the path and store it in a string.
You are doing things backward.

add a textbox and use the keypress event to detect the enter key(13). Set the RootFolder property before you show it. Barring that you could make a custom control or use ideas from these custom folder browser dialogs
