我windowClosing在关闭特定的JFrame之前用来确认.

在关闭之前我得到一个确认对话框,但问题是即使我单击否按钮它也会关闭.有什么帮助吗？

addWindowListener(new WindowAdapter() {

  @Override
  public void windowClosing(WindowEvent we)
  { 
    String ObjButtons[] = {"Yes","No"};
    int PromptResult = JOptionPane.showOptionDialog(null, 
        "Are you sure you want to exit?", "Online Examination System", 
        JOptionPane.DEFAULT_OPTION, JOptionPane.WARNING_MESSAGE, null, 
        ObjButtons,ObjButtons[1]);
    if(PromptResult==0)
    {
      System.exit(0);          
    }
  }
});

我正在尝试使用记录集从数据库中获取数据,并使用经典ASP中的以下代码.我正在使用Windows 7 32位操作系统:

<%
dim con,rs
set con=Server.Createobject("ADODB.Connection")
con.Provider="Microsoft.Jet.OLEDB.4.0"
con.Open "c:\inetpub\wwwroot\New folder\123.mdb"
rs.Open "select * from student",con
for each x in rs.fields
response.write(x.name)
response.write("=")
response.write(x.value)
next
rs.Close
con.Close
%>

错误是:

Microsoft VBScript runtime error '800a01a8'

Object required: ''
