I ic1396 Unregistered / Unconfirmed GUEST, unregistred user! 2002-06-03 #1 我在数据模块中放入了TADOConnection、TADOQuery、TDataSource控件，设计时好用，但 我想动态的改变数据库连接串、SQL语句，却总是提示错误。我该怎样做？

M mlzhou Unregistered / Unconfirmed GUEST, unregistred user! 2002-06-03 #4 adoconnection.connected := fase; adoconnection.connectionstring := '连接串'; adoconnection.connected := true;
adoconnection.connected := fase; adoconnection.connectionstring := '连接串'; adoconnection.connected := true;
