There is no ODBC provider for the Compact Framework. Nor does Windows CE
have the capabilities to open MDB files. Instead you can either use a tool
to convert the database to a device -side format e.g. Sql Server CE, or
write a server component on a desktop PC hosting the MDB file and then call
this from your .NETCF application e.g. over Sockets or Web Services.
