如何动态修改TSQLCONNECTION的连接参数？(100分)

我想动态的改变TSQLCONNCTION的连接PARAMS，用LOADFROM 试了几次没有用，不知道怎么动态的修改？

with ConMySQLMainForm do<br>&nbsp; begin<br>&nbsp; &nbsp; ConnectionName := 'xxxxxx';<br>&nbsp; &nbsp; DriverName := 'MySQL';<br>&nbsp; &nbsp; GetDriverFunc := 'getSQLDriverMYSQL';<br>&nbsp; &nbsp; LibraryName := 'dbexpmysql.dll';<br>&nbsp; &nbsp; VendorLib := 'libmysql.dll';<br>&nbsp; &nbsp; LoginPrompt := False;<br>&nbsp; &nbsp; KeepConnection := False;<br>&nbsp; end;<br>&nbsp; ConMySQLMainForm.BeforeConnect := MySQLBeforeConnect;<br>----------------------------------------------------------<br><br>procedure TMain.MySQLBeforeConnect(Sender: TObject);<br>begin<br>&nbsp; with ConMySQLMainForm do<br>&nbsp; begin<br>&nbsp; &nbsp; params.Values['HostName'] := MySQLHostName;<br>&nbsp; &nbsp; params.Values['Database'] := MySQLDataBase;<br>&nbsp; &nbsp; params.Values['User_Name'] := MySQLUser;<br>&nbsp; &nbsp; params.Values['Password'] := MySQLPassword;<br>&nbsp; &nbsp; params.Values['BlobSize'] := '-1';<br>&nbsp; &nbsp; params.Values['ErrorResourceFile'] := '';<br>&nbsp; &nbsp; params.Values['LocaleCode'] := '0000';<br>&nbsp; end;<br>end;

建议建立ini文件，用它来保存参数，或者直接写到注册表中，修改时直接修改注册表或者ini，这样下次用时直接调用。
