控件数组(添加一个label1,然后再复制5个,共6个,用来显示数字),代码如下:
Private
Sub
Command1_Click()
If
Command1.Caption
=
"抽奖"
Then
Command1.Caption
=
"停止"
Timer1.Enabled
=
True
Else
Timer1.Enabled
=
False
Command1.Caption
=
"抽奖"
End
If
End
Sub
Private
Sub
Form_Load()
Command1.Caption
=
"抽奖"
Timer1.Interval
=
50
Timer1.Enabled
=
False
End
Sub
Private
Sub
Timer1_Timer()

Label1(i).BackColor

首先,页面1中用表单提交数据你要查询的数据代码参考:<form action="对应的servlet类" metohd="post" name="form1">
接着,建立一个selvet类,继承HttpServlet,在selvet类的doPost()方法里写入查询数据库的代码,主要利用request来获取页面1中的参数,通过reponse来给页面2传输数据库查询的结果
代码参考:
Connection con=null
Statement stmt=null
ResultSet rs=null
String name=request.getParameter("name")
Class.forName("oracle.jdbc.driver.OracleDriver")
con = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:test1", "test","stst")
stmt = conn.createStatement()
rs = stmt.executeQuery("select ename,empno,deptno from emp where empno like \'"+name+"')
reponse.setContentType("text/htmlcharset=GB2312")
PrintWriter out=response.getWritertr()
out.println("<html><body>")
out.print("<table border>")
out.print("<tr><td colspan=8 align=center>用户数据</td></tr>")
out.print("<tr>")
while(rs.next)
{
our.print("<tr>")
our.print("<td>"+rs.getString("ename")+</td>)
our.print("<td>"+rs.getString("emono")+</td>)
our.print("<td>"+rs.getString("depno")+</td>)
our.print("</tr>")
}
out.print("</tr>")
out.print("</table>")
out.print("</body></html>")
out.close()
rs.close()
stmt.close()
con.close()
源文件是下载不了的,只能下载swf文件。最简直的方法是:
浏览器的“工具---internet选项----浏览历史记录设置----查看文件”,去文件夹里面找
