?_??
Public??Function?GetCompletionList(?ByVal?prefixText?As??String?,?ByVal?count?As??Integer?)?As??String?()??
?Dim?myConnection?As??OleDbConnection??
?Dim?myCommand?As??OleDbCommand??
?Dim?dbname?As??String???
dbname?=?Server.MapPath(?"location.accdb"?)??
myConnection?=?New?OleDbConnection(?"Provider=Microsoft.ACE.OLEDB.12.0;DATA?Source="??&?dbname)??
????myConnection.Open()??
?Dim?list?As??New?List(Of?String?)??
myCommand?=?New?OleDbCommand(?"SELECT?DISTINCT(columnName)?FROM?tableName?WHERE?columnName?LIKE?'"?+?prefixText?&?"%"?+?"'"?,?myConnection)??
?Dim?reader?As??OleDbDataReader?=?myCommand.ExecuteReader()??
?Do??While??reader.Read??

以上即可存崖。
AJAX日期控件的使用也很方便冻记，如：
[xhtml]??view plain??copy
<?asp:TextBox??ID?=?"txtDate"??runat?=?"server"??Columns?=?"24"?>????
